Answer:
18
Step-by-step explanation:
For this problem, we will simply plug in the values of a and b into the respective variables in the expression 3ab to "evaluate" the expression.
a = 2; b = 3
3ab
Note, that when variables like a and b are smashed with a constant, the use of multiplication is in play.
3ab = 3 * a * b
With this in mind, let's plug in the values of a and b into the expression.
3ab
= 3 (2) (3)
= 3 (6)
= 18
Hence, 3ab evaluated when a=2 and b=3 is 18.

The area of the trapezoid will be 4 sq. unit.
What precisely is a trepezium?
Trapezoids are made up of two parallel and two oblique sides. A Trapezium is another name for it. A trapezoid is a closed four-sided shape or figure with a space-filling perimeter. It is a 2D figurine rather than a 3D figure. A trapezoid's bases are the sides that are parallel to one another. Legs are non-parallel sides, often known as lateral sides. The space between its parallel sides determines its height.
A trapezium's area is equal to 1/2*(a+b)*h.
where h is the height or distance between two parallel lines
The lines a and b are parallel.
Now,
From given coordinated
the length of two parallel lines will be 5-2=3 and 3-2= 1
and height between them is 3-1=2
then area of trapezium will be =1/2*(3+1)*2
=8/2
=4 sq. unit
Hence,
The area of the trapezoid will be 4 sq. unit.

Let f be the function given by f(x) 9x. If four subintervals of equal length are used, what is the value of the right Riemann sum approximation for (x) dx?
The value of the right Riemann sum approximation for integral ∫₀² f(x) dx is (c) 60.
The right Riemann sum approximation is obtained by dividing the interval [0, 2] into four subintervals of equal length and evaluating the function at the right endpoints of each subinterval. In this case, each subinterval has a length of (2-0)/4 = 0.5. The right endpoints of the subintervals are 0.5, 1.0, 1.5, and 2.0.
To calculate the right Riemann sum, we evaluate the function at these right endpoints and sum up the values multiplied by the subinterval length.
f(0.5) = \(9^{0.5\) = 3
f(1) = 9¹ = 9
f(1.5) = \(9^{1.5\) = 27
f(2) = 9² = 27
The right Riemann sum is then
= (0.5 * f(0.5)) + (0.5 * f(1.0)) + (0.5 * f(1.5)) + (0.5 * f(2.0))
= 0.5 * (3 + 9 + 27 + 81)
= 60.

A positive integer is 7 less than another. If 5 times the reciprocal of the smaller integer is subtracted from 3 times the reciprocal of the larger integer, then the result is Find all pairs of integers that satisfy this condition Select the correct answer below: O 12,19 O 12,5 19,26 no solutions
Let's represent the smaller integer by x. Larger integer is 7 more than the smaller integer, so it can be represented as (x+7). The reciprocal of an integer is the inverse of the integer, meaning that 1 divided by the integer is taken. The reciprocal of x is 1/x and the reciprocal of (x+7) is 1/(x+7). The smaller integer is 6 and the larger integer is (6+7) = 13.
Now we can use the information given in the problem to form an equation. 3 times the reciprocal of the larger integer subtracted by 5 times the reciprocal of the smaller integer is equal to 4/35.(3/x+7)−(5/x)=4/35
Multiplying both sides by 35x(x+7) to eliminate fractions:105x − 15(x+7) = 4x(x+7)
Now we have an equation in standard form:4x² + 23x − 105 = 0We can solve this quadratic equation by factoring, quadratic formula or by completing the square.
After solving the quadratic equation we can find two integer solutions:
x = -8, x = 6.25Since we are given that x is a positive integer, only the solution x = 6 satisfies the conditions.
Therefore, the smaller integer is 6 and the larger integer is (6+7) = 13.
The only pair of integers that satisfy the given condition is (6,13).Answer: One pair of integers that satisfies the given condition is (6,13).

Please answer the first question attached (question 8) and it would be very much appreciated if you could help me solve the other questions as well please. I will give you a very hugh rating and good comment!
8) Determine the distance between the point (3,7) and the line 2x - 5y + 8 = 0
9) For the line given by vector equation r = (1, - 1, 2) + t (1,3,-1), tER
For question 8, we can use the formula for the distance between a point and a line. The formula is:
distance = |ax + by + c| / √(a^2 + b^2)
where (x,y) is the point and ax + by + c = 0 is the equation of the line.
First, let's find the equation of the line 2x - 5y + 8 = 0 in slope-intercept form:
2x - 5y + 8 = 0
-5y = -2x - 8
y = (2/5)x + 8/5
So, the slope of the line is 2/5 and a point on the line is (0,8/5). Now we can plug in the values into the distance formula:
distance = |2(3) - 5(7) + 8| / √(2^2 + (-5)^2)
distance = 2 / √29
Therefore, the distance between the point (3,7) and the line 2x - 5y + 8 = 0 is 2 / √29.
For question 9, the vector equation of the line can be written as:
x = 1 + t
y = -1 + 3t
z = 2 - t
We can see that the direction vector of the line is <1,3,-1> and a point on the line is (1,-1,2).
That's all I can do for now. Let me know if you need further assistance with the other questions.
To find the distance between the point (3, 7) and the line 2x - 5y + 8 = 0, you can use the point-to-line distance formula:
Distance = |Ax + By + C| / sqrt(A^2 + B^2)
where (A, B, C) are the coefficients of the line equation Ax + By + C = 0, and (x, y) are the coordinates of the given point.
For the line 2x - 5y + 8 = 0, we have A = 2, B = -5, and C = 8. The given point is (3, 7), so x = 3 and y = 7.
Now plug these values into the formula:
Distance = |(2)(3) + (-5)(7) + 8| / sqrt((2)^2 + (-5)^2)
Distance = |6 - 35 + 8| / sqrt(4 + 25)
Distance = |-21| / sqrt(29)
Distance = 21 / sqrt(29)
So, the distance between the point (3,7) and the line 2x - 5y + 8 = 0 is 21 / sqrt(29) units.

find an equation of the curve that passes through the point (0, 1) and whose slope at (x, y) is 5xy. (note: start your answer with y
The equation of the curve that passes through the point (0, 1) and has a slope of 5xy at any point (x, y) is y = (5/2) * x^2y + 1. This equation represents a curve where the y-coordinate is a function of the x-coordinate, satisfying the conditions.
To determine an equation of the curve that satisfies the conditions, we can integrate the slope function with respect to x to obtain the equation of the curve. Let's proceed with the calculations:
We have:
Point: (0, 1)
Slope: 5xy
We can start by integrating the slope function to find the equation of the curve:
∫(dy/dx) dx = ∫(5xy) dx
Integrating both sides:
∫dy = ∫(5xy) dx
Integrating with respect to y on the left side gives us:
y = ∫(5xy) dx
To solve this integral, we treat y as a constant and integrate with respect to x:
y = 5∫(xy) dx
Using the power rule of integration, where the integral of x^n dx is (1/(n+1)) * x^(n+1), we integrate x with respect to x and get:
y = 5 * (1/2) * x^2y + C
Applying the initial condition (0, 1), we substitute x = 0 and y = 1 into the equation to find the value of the constant C:
1 = 5 * (1/2) * (0)^2 * 1 + C
1 = C
Therefore, the equation of the curve that passes through the point (0, 1) and has a slope of 5xy at any point (x, y) is:
y = 5 * (1/2) * x^2y + 1
Simplifying further, we have:
y = (5/2) * x^2y + 1

Find all values of x that make the triangles congruent. Explain your reasoning.
Answer:
The values of x that make the triangles congruent.
x = 6 and x = 3
Step-by-step explanation:
Given
AC = 5x-2DC = 3x+10AB = 5xDB = 4x+3Given that the triangles are congruent.
According to the SAS (Side-Side-Side)
AC = DC
AB = DB
so
AC = DC
substituting AC = 5x-2 and DC = 3x+10
5x-2 = 3x+10
5x-3x = 10+2
2x = 12
divide both sides by 2
2x/2 = 12/2
x = 6
and
AB = DB
substituting AB = 5x and DB = 4x+3
5x = 4x+3
5x-4x = 3
x = 3
Therefore, the values of x that make the triangles congruent.

John has a bag of marbles. He gives away 3/4 of the marbles to his friend. Later, he receives another bag containing 2/4 of the original number of marbles. How many marbles does John have now?
Answer:
Total is 3
Step-by-step explanation:
AI-generated answer
Let's start by finding out how many marbles John had initially. We can do this by using the information given in the problem.
Let the original number of marbles be x.
John gave away 3/4 of his marbles, which means he has 1/4 of the original number of marbles left. We can express this as:
1/4 x = the number of marbles John has left
If we solve for x, we get:
4/1 * 1/4 x = 4/1 * the number of marbles John has left
x = 4 * the number of marbles John has left
Now we know that John had 4 times the number of marbles he has left.
Next, John receives another bag of marbles containing 2/4 (which is the same as 1/2) of the original number of marbles.
We can express this as:
1/2 x = the number of marbles in the new bag
To find the total number of marbles John has now, we can add the number of marbles he has left to the number of marbles in the new bag:
Total number of marbles = the number of marbles John has left + the number of marbles in the new bag
Total number of marbles = 1/4 x + 1/2 x
Total number of marbles = (1/4 + 1/2) x
Total number of marbles = (3/4) x
We know that x = 4 times the number of marbles John has left, so we can substitute this into the equation:
Total number of marbles = (3/4) * 4 * the number of marbles John has left
Total number of marbles = 3 * the number of marbles John has left
Therefore, the total number of marbles John has now is 3 times the number of marbles he has left.

when converting a rectangular equation into polar form or converting polar equations into rectangular form, what are the conversion equations you can use? quixlet
Rectangular coordinates use the x and y axes, while polar coordinates use the radius and angle. By converting between these coordinate systems, we can gain new insights into the same equation and solve problems using different methods.
When converting rectangular equations to polar form, we can use the following conversion equations:
1. r^2 = x^2 + y^2 (this is the equation for the radius in terms of x and y)
2. tanθ = y/x (this is the equation for the angle θ in terms of x and y)
Using these equations, we can convert any rectangular equation (in terms of x and y) to its equivalent polar form (in terms of r and θ).
On the other hand, when converting polar equations to rectangular form, we can use the following conversion equations:
1. x = r*cos(θ) (this is the equation for x in terms of r and θ)
2. y = r*sin(θ) (this is the equation for y in terms of r and θ)
Using these equations, we can convert any polar equation (in terms of r and θ) to its equivalent rectangular form (in terms of x and y).
It's important to note that when converting equations between rectangular and polar forms, we're essentially changing the coordinate system used to describe the equation.

j) employees that consist of 4 people who take public transit, 3 people who drive to work, and 3 people who do neither is 6,270,840
a) This is a combination problem, where the order of selection does not matter. The formula for the number of combinations of n objects taken r at a time is \(nCr = n! / (r! * (n-r)!)\), where n is the total number of objects and r is the number of objects being selected. In this case, there are 32 employees and we want to select 10 of them, so the number of different groups of 10 employees that can be selected is:
\(32C10 = 32! / (10! * (32-10)!) = 14,307,292\)
b) We can add the number of groups that consist only of employees who take public transit to the number of groups that consist only of employees who drive to work. To find the number of groups that consist only of employees who take public transit, we can choose 10 employees from the 12 who take public transit. Similarly, to find the number of groups that consist only of employees who drive to work, we can choose 10 employees from the 11 who drive to work. Therefore, the number of possible groups of 10 employees that consist only of employees who either take public transit or drive to work is:
\(12C10 + 11C10 = 66 + 11 = 77\)
c) We can choose 10 employees from the 12 who take public transit, so the number of possible groups of 10 employees that consist entirely of employees who take public transit is:
\(12C10 = 66\)
d) We can choose 10 employees from the 11 who drive to work, so the number of possible groups of 10 employees that consist entirely of employees who drive to work is:
\(11C10 = 11\)
e) We can choose 10 employees from the 20 who either drive to work or do neither, so the number of possible groups of 10 employees that do not include anyone who takes public transit is:
\((20C10) = 184,756\)
f) We can choose 10 employees from the 21 who either take public transit or do neither, so the number of possible groups of 10 employees that do not include anyone who drives to work is:
\((21C10) = 352,716\)
g) We can subtract the number of possible groups of 10 employees that do not include anyone who takes public transit from the total number of possible groups of 10 employees. Therefore, the number of possible groups of 10 employees that consist of at least one person who takes public transit is:
\(32C10 - 20C10 = 14,122,536\)
h) We can subtract the number of possible groups of 10 employees that do not include anyone who drives to work from the total number of possible groups of 10 employees. Therefore, the number of possible groups of 10 employees that consist of at least one person who drives to work is:
\(32C10 - 21C10 = 14,054,576\)
i) We can choose 5 employees from the 12 who take public transit and 5 employees from the 11 who drive to work. Therefore, the number of possible groups of 10 employees that consist of 5 people who take public transit and 5 people who drive to work is:
\(12C5 * 11C5 = 792 * 462 = 365,904\)
j) We can choose 4 employees from the 12 who take public transit, 3 employees from the 11 who drive to work, and 3 employees from the 9 who do neither. Therefore, the number of possible groups of 10 employees that consist of 4 people who take public transit, 3 people who drive to work, and 3 people who do neither is:

B. 2 and OD. 15 are not possible lengths for the third side of the triangle.
To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Given that two sides have lengths 6 and 9, we can analyze the possibilities:
6 + 9 > x
x > 15 - The sum of the two known sides is greater than any possible third side.
6 + x > 9
x > 3 - The length of the unknown side must be greater than the difference between the two known sides.

5.8x10^-1 - 7.4x10^0 in scientific notation.
5.8 × 10⁻¹ = 0.58
