Answer:
y = -0.3x + 103
Step-by-step explanation:
✔️Find the slope (b):
Slope = ∆y/∆x
Using, (25, 95.5) and (35, 92.5),
Slope (m) = (92.5 - 95.5)/(35 - 25) = -3/10 = -0.3
✔️Find the y-intercept (b):
Substitute (x, y) = (25, 95.5) and m = -0.3 into y = mx + b
95.5 = -0.3(25) + b
95.5 = -7.5 + b
95.5 + 7.5 = b
103 = b
b = 103
✔️To write the equation, substitute m = -0.3 and b = 103 into y = mx + b
Thus:
y = -0.3x + 103

4tan(x)-7=0 for 0<=x<360
Answer:
x = 65.26 degrees or x = 245.26 degrees.
Step-by-step explanation:
To solve the equation 4tan(x)-7=0 for 0<=x<360, we can first isolate the tangent term by adding 7 to both sides:
4tan(x) = 7
Then, we can divide both sides by 4 to get:
tan(x) = 7/4
Now, we need to find the values of x that satisfy this equation. We can use the inverse tangent function (also known as arctan or tan^-1) to do this. Taking the inverse tangent of both sides, we get:
x = tan^-1(7/4)
Using a calculator or a table of trigonometric values, we can find the value of arctan(7/4) to be approximately 65.26 degrees (remember to use the appropriate units, either degrees or radians).
However, we need to be careful here, because the tangent function has a period of 180 degrees (or pi radians), which means that it repeats every 180 degrees. Therefore, there are actually two solutions to this equation in the given domain of 0<=x<360: one in the first quadrant (0 to 90 degrees) and one in the third quadrant (180 to 270 degrees).
To find the solution in the first quadrant, we can simply use the value we just calculated:
x = 65.26 degrees (rounded to two decimal places)
To find the solution in the third quadrant, we can add 180 degrees to the first quadrant solution:
x = 65.26 + 180 = 245.26 degrees (rounded to two decimal places)
So the solutions to the equation 4tan(x)-7=0 for 0<=x<360 are:
x = 65.26 degrees or x = 245.26 degrees.
What percent of values is between the first and third quartiles?
The data set is 50, 75, 100, 125, 150, 175, 200, 225, 250
Answer:
\(55.555...\ (\%)\)
Step-by-step explanation:
What percent of values is between the first and third quartiles
\(\text{Quartile 1} =\frac{75+100}{2} =87.5\)
\(\text{Quartile 2} =\frac{200+225}{2} =212.5\)
50 < 75 < 87.5 < 100 < 125 < 150 < 175 < 200 < 212.5 < 225 < 250
Then we have 5 values between the first and third quartiles which are :
100, 125, 150, 175, 200
Therefore,
The percent of values between the first and third quartiles is :

Find the area of the surface generated when the given curve is revolved about the given axis. 5x^1/3
Answer:
\(\mathbf{ \dfrac{\pi}{675}\Big[ 34\sqrt{34} -125\Big] }\)
Step-by-step explanation:
The curve x = f(y)
The area of the surface around the y-axis from y = a → y = b is:
\(=\int^b_a 2 \pi x \sqrt{1 + (\dfrac{dx}{dy})^2} \ dy\)
From the given curve:
\(y = (5x)^{^{\dfrac{1}{3}}\) ; assuming the region bounded by the curve is 0 ≤ y ≤ 1
So;
\(y = (5x)^{^{\dfrac{1}{3}}\)
5x = y³
\(x = \dfrac{1}{5}y^3\)
The differential of the above equation Is:
\(\dfrac{dx}{dy}= \dfrac{1}{5} \times (3y^2)\)
\(\dfrac{dx}{dy}= \dfrac{3}{5}y^2\)
Now, we have the area of the surface produced around the curve \(x = \dfrac{1}{5}y^3\) through the y axis from the region y = 0 to y = 1
∴
\(= \int ^1_0 2 \pi \dfrac{1}{5}y^3 \sqrt{1 + (\dfrac{3}{5}y^2)^2} \ dy\)
\(= \dfrac{ 2 \pi}{5} \int ^1_0 y^3 \sqrt{1 + \dfrac{9}{25}y^4} \ dy\)
\(= \dfrac{ 2 \pi}{5} \int ^1_0 y^3 \sqrt{ \dfrac{25+9y^4}{25}} \ dy\)
\(= \dfrac{ 2 \pi}{5} \int ^1_0 y^3 \dfrac{\sqrt{25+9y^4}}{5}} \ dy\)
\(= \dfrac{ 2 \pi}{25} \int ^1_0 y^3 \sqrt{25+9y^4}} \ dy\)
Let make \(u = \sqrt{25+9y^4}\)
It implies that:
\(u^3 = (25+9y^4)\sqrt{25+9y^4}\)
\(u = \sqrt{25+9y^4} \\\\ du = \dfrac{1}{2\sqrt{25 +9y^4}}(36y^3) \ dy\)
\(du = \dfrac{18y^3}{\sqrt{25 +9y^4}}\ dy\)
\(y^3dy = \dfrac{1}{18}\sqrt{25+9y^4} \ du\)
when y = 0 ;
\(u = \sqrt{25+ 9(0)^4}\)
\(u = \sqrt{25}\)
u = 5
when y = 1;
\(u = \sqrt{25+ 9(1)^4}\)
\(u = \sqrt{25+9}\)
\(u = \sqrt{34}\)
∴
The equation \(\dfrac{ 2 \pi}{25} \int ^1_0 y^3 \sqrt{25+9y^4}} \ dy\) can be written as:
\(= \dfrac{2 \pi}{25} \int ^{\sqrt{34}}_{5} (u ) \dfrac{1}{18} \ udu\)
\(= \dfrac{2 \pi}{25\times 18} \int ^{\sqrt{34}}_{5} (u ) \ udu\)
\(= \dfrac{\pi}{225} \int ^{\sqrt{34}}_{5} (u^2 ) \ udu\)
\(= \dfrac{\pi}{225}\Big[ \dfrac{u^3}{3} \Big] ^{\sqrt{34}}_{3}\\\)
\(\mathbf{= \dfrac{\pi}{675}\Big[ 34\sqrt{34} -125\Big] }\)

Suppose it costs $2,500 to buy a defibrillator. Find the expected value of owning a defibrillator if there is a 4% probability that Johnson Club will lose a lawsuit regarding its operation, with each lawsuit resulting in Johnson Club being liable in the amount of $1,000,000.
Answer:
$37,500
Step-by-step explanation:
Expected value is the sum of the outcomes times their probability.
E(X) = (-2500) (1) + (1,000,000) (0.04)
E(X) = 37,500
Another way of calculating it:
E(X) = (-2500+0) (0.96) + (-2500+1,000,000) (0.04)
E(X) = 37,500
Is the line through points (-3,2) and (4, -1) parallel to the line that contains the points (1,3) and (-2, -4)?
Are the two lines parallel?
How do you know?
Considering the expression of a line, they do not have the same value of m. So, the two lines are not parallel.
Linear equation o lineA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Knowing two points (x1, y1) and (x2, y2) of a line, the slope m of said line can be calculated using the following expression:
m= (y2 - y1)÷ (x2 - x1)
Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained.
Parallel lineParallel lines are two lines that are always at the same distance from each other and that prolonged towards infinity never touch.
Two lines are parallel if they have the same slope and different y-intercepts. That is, they have the same value of m and different value of b.
Lines in this caseIn this case, you can calculated the slope of the two lines as:
Being (x1,y1)= (-3,2) and (x2,y2)= (4, -1), the slope m can be calculated as:
m= (-1 -2)÷ (4 - (-3))
Solving:
m= (-3)÷ 7
m= -3/7
Being (x1,y1)= (1,3) and (x2,y2)= (-2,-4), the slope m can be calculated as:
m= (-4 -3)÷ (-2 -1)
Solving:
m= (-7)÷ (-3)
m= 7/3
You can observe that they do not have the same value of m. Finally, the two lines are not parallel.

The volume of a cone is 13.4m cubed and the radius is 3.2m what is the height
Answer:
The height is 1.25m.
Step-by-step explanation:
Volume = 1/3 πr²h
Given:
V = 13.4 m³
r = 3.2 m
Asked: height (h)
Substitute the formula with the given values then solve
13.4m³ = 1/3π(3.2m)²h
13.4(3) = 10.24πh
40.2 = 10.24πh
h = 40.2/10.24π
h = 1.25m
The height of the cone is 1.25 meters.
We know that the volume of the cone is given by
V = (1 / 3) * π * r ^2 * h................equation 1
where,
V is the volume of the cone.
r is the radius of the cone's base
h is the height
The volume and radius of the cone are given,
V = 13.4 m
r = 3.2m
substituting these values in equation 1 we get,
13.4 = (1 / 3) * 3.14 * 3.2 ^ 2 * h
on simplifying further
13.4 = 10.717 * h
h = 1.25m
The height of the cone is 1.25 meters.

Using log evaluate 3^x=10
Answer:
x ≈ 2.09590327429
Step-by-step explanation:
You want the solution to 3^x = 10 using logarithms.
LogsTaking logarithms of both sides of the given equation, we have ...
x·log(3) = log(10)
Dividing by the coefficient of x gives ...
x = log(10)/log(3)
x ≈ 2.09590327429
__
Additional comment
If the logarithm to the base 10 is used, then this becomes ...
x = 1/log₁₀(3)
The meaning of "log( )" varies with the context. In high-school algebra, it usually means "log₁₀( )". In other contexts, it may mean "ln( )", the natural logarithm.
For the purpose here, it doesn't matter what base the logarithms have, as long as log(10) and log(3) are to the same base.

The approximate value of x that satisfies the equation 3^x = 10 is approximately 1.46497.
To evaluate the equation 3^x = 10 using logarithms, we can take the logarithm of both sides of the equation. The most commonly used logarithm is the base 10 logarithm, also known as the common logarithm (log).
Taking the log of both sides, we get:
log(3^x) = log(10)
Now, we can apply the logarithmic property that states log(a^b) = b * log(a). Applying this property to the left side of the equation:
x * log(3) = log(10)
Next, we can divide both sides of the equation by log(3) to isolate the variable x:
x = log(10) / log(3)
Using a calculator, we can evaluate the right side of the equation:
x ≈ 1.46497
Therefore, the approximate value of x that satisfies the equation 3^x = 10 is approximately 1.46497.
