Answer:
It's the third choice.
Step-by-step explanation:
IF y varies inversely as x then y = k/x where k is a constant,
and k = xy
For the 3rd choice

An average male lion in captivity requires
8 pounds of food per day. The equation y = 8x
can be used to represent this situation. What is
the constant of proportionality? What does the
constant of proportionality represent in the
context of the problem? (Example 1)
4.
Answer: 8 is actually the constant of proportionality, since it is the number that stays the same regardless of the change in x and y.
Step-by-step explanation:
Let's say you want to know how many pounds of meat a male lion would eat in a month in order to purchase for the zoo the correct amount of food needed. Let's assume the month was 30 days. we know that 8 is the amount of food per day (that number will not change because it is a constant.
so 30 x 8 = 240 which is what y is for the 30 days.
if you needed two weeks, 14 days. 14 x 8 = 112 pounds for the 14 days.
So you see 8 stays the same for each scenario, so it is the constant that is used for all values of x to find y.

Find area of trapezium with height 8cm and the sum of its parallel sides as 15cm
Answer:
The Area of the trapezium is \(60cm^2\)
Step-by-step explanation:
Given,
Height (h)= 8cm
Sum of the parallel sides (a+b)= 15cm
Area of trapezium = \(1/2*h*(a+b)\)
=\(1/2*8*15\)
=\(4*15\)
Area of trapezium=60cm^2
Answer: Area = 60 cm²
Step-by-step explanation:
To find the area of a trapezium we use the formula
Area of trapezium = 1/2 (sum of parallel sides) × height
∴ Area = 1/2 ×15 cm × 8 cm
= 60 cm²

Consider the polynomial
(4mn^2n - 2mn + 6) + (6mn^2 - 1) - (mn^2 - 2 + 9mn)
Combine all like terms and enter the coefficients for each term into the blanks below
The required coefficients are:4, -1, -11, and 7.
Coefficients refer to the numerical values that are assigned to variables in mathematical equations, models, or formulas. They indicate the relative importance or contribution of each variable in the equation. Coefficients are used to determine the relationship between variables and are often estimated through statistical analysis or optimization techniques.
In algebraic equations, coefficients are the numbers multiplied by variables. For example, in the equation 2x + 3y = 5, the coefficients are 2 and 3.
In statistical models, such as linear regression, coefficients represent the slopes or weights assigned to the predictor variables. These coefficients indicate how much the response variable is expected to change for a unit change in the corresponding predictor variable, assuming all other variables are held constant.
We need to consider the polynomial:
(4mn^2n - 2mn + 6) + (6mn^2 - 1) - (mn^2 - 2 + 9mn)
To combine the like terms and find the coefficients of each term, we can write the polynomial in the following form:
4mn^2n - 2mn + 6 + 6mn^2 - 1 - mn^2 + 2 - 9mn
Taking the coefficients of the terms with "mn^2"4mn^2n - mn^2
Taking the coefficients of the terms with "mn"-2mn - 9mn = -11mn

2²+6²=c²
4+36=c²
40=c²
c²=40
Square root both sides
c=\(\sqrt{40}\)

Use the given conditions to write an equation for the line in the indicated form.
Passing through (2, 2) and perpendicular to the line whose equation is y = 4x + 7;
point-slope form
A)y=-4x-10
B)y-2=-1/4(x-2)
C)y-2=1/4(x+2)
D)y-2=1/4(x-2)
Answer:
B) y - 2 = (-1/4)(x - 2)
Step-by-step explanation:
Start with the equation of the given line: y = 4x + 7.
Determine the slope of the given line, which is 4.
Since the perpendicular line has a negative reciprocal slope, the perpendicular line's slope is -1/4.
Use the point-slope form of a linear equation: y - y₁ = m(x - x₁), where (x₁, y₁) is the given point and m is the slope.
Substitute the values x₁ = 2 and y₁ = 2 into the point-slope equation: y - 2 = (-1/4)(x - 2).
Simplify by distributing -1/4 to (x - 2): y - 2 = (-1/4)x + 1/2.
Add 2 to both sides to isolate y: y = (-1/4)x + 1/2 + 2.
Simplify further: y = (-1/4)x + 5/2.
The equation in point-slope form for the line passing through (2, 2) and perpendicular to y = 4x + 7 is y - 2 = (-1/4)(x - 2), which matches option B.

What is the slope of the line that is represented by the values in the table above?
Answer:
\( slope (m) = 6 \)
Step-by-step explanation:
To get the slope of the line of the given table of values, all we need is just 2 coordinate pairs from the table. We can pick any two.
Let's use, (-1, 0), and (0, 6).
Apply the formula, \( \frac{y_2 - y_1}{x_2 - x_1} \), where,
\( (-1, 0) = (x_1, y_1) \)
\( (0, 6) = (x_2, y_2) \)
Thus:
\( m = \frac{6 - 0}{0 - (-1)} \)
\( m = \frac{6}{1} \)
\( slope (m) = 6 \)

How does an object become electrically charged?
A) Though the transfer of charges from one object to another
B) Through the movement of heat from one object to another
C) Through the transfer of sound from one object to another
D) Through the movement of water from one object to another
A is the correct option:) Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same. This is the law of conservation of charge. Conduction occurs when there is direct contact between materials that differ in their ability to give up or accept electrons.

Which sequence of transformations was applied to the parent tangent function to create the function m(x) = 2tan(3x+4)
The function m(x) = 2tan(3x+4) is obtained by applying a sequence of transformations to the parent tangent function.
To determine the sequence of transformations, let's break down the given function:
1. Inside the tangent function, we have the expression (3x+4). This represents a horizontal compression and translation.
2. The coefficient 3 in front of x causes the function to compress horizontally by a factor of 1/3. This means that the period of the function is shortened to one-third of the parent tangent function's period.
3. The constant term 4 inside the parentheses shifts the function horizontally to the left by 4 units. So, the graph of the function is shifted to the left by 4 units.
4. Outside the tangent function, we have the coefficient 2. This represents a vertical stretch.
5. The coefficient 2 multiplies the output of the tangent function by 2, resulting in a vertical stretch. This means that the graph of the function is stretched vertically by a factor of 2.
In summary, the sequence of transformations applied to the parent tangent function to create the function m(x) = 2tan(3x+4) is a horizontal compression by a factor of 1/3, a horizontal shift to the left by 4 units, and a vertical stretch by a factor of 2.
Example:
Let's consider a point on the parent tangent function, such as (0,0), which lies on the x-axis.
After applying the transformations, the corresponding point on the function m(x) = 2tan(3x+4) would be:
(0,0) -> (0,0) (since there is no vertical shift in this case)
This example helps illustrate the effect of the transformations on the graph of the function.

Answer:
55m is the magnitude of the average distance of the car during this time interval.
The correct option is D.
How is distance measured in physics?
The metre is the Si derived unit for distance (m). Long distances can be measured in kilometres, whereas little distances can be gauged in millimetres (cm) (km). For instance, you might measure the length in centimetres between the bottom and top of a piece of paper and the kilometres from your home and school.
What is Distance?
The total movement of an object, independent of direction, is its distance. No matter where an object starts or ends, distance can be defined as the amount of space it has covered.
Briefing:
The equation for the Total distance is mathematically given as
d=initial distance -final distance
d=90-35
d=55m
Step-by-step explanation:
27.5° will be the value of m∠C. Thus option A is correct.
What is an angle sum property?A closed shape with both inner and exterior angles, a triangular is created by three lines. Because when measurements of the additional two angles are known, one can utilize the angle sum property to determine the measure of an undetermined interior angle. To calculate the third angle's measurement, add the first two angles together and reduce their combination from 180 degrees.
The information that is provided is with respect to the triangle ΔABC
In which the value of the two triangles is given as m∠A = 28.7° and m∠B = 123.8°
To determine the third angle m∠C angle sum property will be used.
180 = m∠A + m∠B + m∠C
180 = 28.7° + 123.8° + m∠C
180 = 152.5 + m∠C
m∠C = 180 - 152.5
m∠C = 27.5°
The reaming angle will be 27.5°. Therefore, option A is the correct option.
