For the following graph, it is found that:
It represents a function, as it value of x is mapped to only one value of y.The inverse is a function, as the graph is one-to-one, that is, each value of y is mapped to only one value of x.When does a graph represents a function?A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y.
For the graph in this problem, the statement is true, hence the graph is a function.
Is the inverse a function?The inverse of a graph will be a function if the original function is one-to-one, that is, each value of y is mapped to only one value of x, meaning that the graph has no horizontally aligned points.
This is also true for this function, hence the inverse is a function.

A family is renting an apartment. For 2007, the rent is 1634 per month. The monthly rent for 2007 is 7.5% higher than the monthly rent in 2006. Determine the monthly rent in 2006
Answer:
$1634*.925=$1511.45
Step-by-step explanation:
100%-7.5%=92.5% / 100 = .925 then multiply by the value of 2007 which is $1634... 1634*.925=1511.45

Two angles are supplementary. One has a measure that is five times as large as the other. Find the two angle measures.
Answer:
30° and 150°
Step-by-step explanation:
supplementary means that the sum of the measures = 180
let's say 1 angle is labled ∠A and the other ∠B
m∠A + m∠B = 180°
however, m∠A = 5 * m∠B
so, by substituting that:
5*m∠B + m∠B = 180°
6*m∠B = 180°
m∠B = 30°
m∠A = 150°

Answer:
Since figure is not given, assume drawing a rectangle and label it from left top to right top as A and B. Similarly label it as C and D from bottom left to right. Draw a semicircle starting from C to D inside the rectangle.
You are asked to find area of shaded region which I assume is semicircular part.
Area of a circle is determined by Pi × r ^2
r is the radius of circle which is half of diameter. The diameter of circle is same as width of rectangle. So radius = 7/2 = 3.5 mm And area of shaded region is
1/2(Pi×r^2) = 1/2(3.14×3.5^2) = 19.2325 sq mm

1) Area of each circle = 0.5625π
There are 2 identical circles in the cylinder.
So the total area of all the circles is; 1.125π square inches
2) One side of the rectangle is; 1.5π
The other side of the rectangle is; 4 inches
The area of the rectangle is approximately; 6π square inches
3) The total area of the can is; 7.125π square inches
What is the total area of the composite shape?
We can see that the can is broken down into two circles with one atop and one beneath the rectangle. Thus;
1) Area of Circle on top and at bottom = πr² = π * 0.75²
Area of each circle = 0.5625π
There are 2 identical circles in the cylinder.
So the total area of all the circles is 2(0.5625π) = 1.125π square inches
2) One side of the rectangle is; 2πr = 2 * π * 0.75 = 1.5π
The other side of the rectangle is; 4 inches
The area of the rectangle is approximately; 4 * 1.5π = 6π square inches
3) The total area of the can = 6π square inches + 1.125π square inches = 7.125π square inches

In an examination given to a class of 20 students, the following test scores were obtained.
45 45 50 50 55 60 70 75 75 80
80 85 85 85 85 90 95 95 95 100
a) Find the mean (or average) score, the mode, and the median score.
b) Which of these three measures of central tendency do you think is the least representative of the set of scores?
Answer:
Mean = 75
Median = 80
Mode = 85
The mode
Step-by-step explanation:
Given the data :
45 45 50 50 55 60 70 75 75 80 80 85 85 85 85 90 95 95 95 100
Rearranged data :
45, 45, 50, 50, 55, 60, 70, 75, 75, 80, 80, 85, 85, 85, 85, 90, 95, 95, 95, 100
The mean score :
ΣX / n ; n = sample size = 20
ΣX = 1500
Mean = 1500 / 20 = 75
Mode = most frequently occurring = 85 ( frequency of 4)
Median = 0.5(n + 1)th term
Median = 0.5(20 + 1)th term
Median = 0.5(21) th term
Median = 10.5th term = (10 + 11)th term / 2
Median = (80 + 80) / 2 = 160 / 2 = 80

A nurse assesses a 66 - year - old client who is attempting to quit smoking . The client states , " I started smoking at age 16 , and smoked one pack each day until 10 years ago . Then I decreased to a half of a pack per day . " How many pack - years should the nurse document for this client ?
The nurse should document for this client as 45 pack years.
Pack year is determined by dividing the quantity of packs smoked daily by the number of years the smoker has smoked.
total years of smoking = current age of the client - the year he started smoking
= 66 - 16
50 years of smoking
For 40 years he smoked 1 pack per day but then he reduced it to a half pf a pack per day
= 40 x 1 + 10 x 0.5
= 45 pack- years
The nurse should document for this client as 45 pack years as the client has started smoking at age 16 , and smoked one pack each day until 10 years ago then he had decreased to a half of a pack per day.

Certain types of songs tend to have a call-and-response structure because A. It can have many different sections
What is call and response?A call and response in music is a series of two independent phrases that are typically composed in separate portions of the piece, with the second phrase being heard as a direct remark or answer to the first.
Direct imitation between instruments, a questioning phrase and subsequent response, a statement of affirmation from one instrument to another, or variations on a direct call by a group of instruments are examples of call and response.

If x varies directly as y and z and inversely as the square
of r, and x = 16 when y = 3, z = 12 and r = 3, find
x when y = 5, z = 30, and r
r =10
Answer:
x = 6
Step-by-step explanation:
Take the statement x varies directly as y and z
This means value of x is directly proportional to the value of y and z represented as x ∝ yz which can be represented as x = k.y.z where k is a constant known as the constant of proportionality
If x varies inversely as the square of r we represent this as x ∝ 1/r² or in equation form x = k/r²
Since the value of x is dependent on the values of y, z and jointly we have a single equation of proportionality:
[tex]\bold{x= k\cdot\frac{yz}{r^{2}}}[/tex]
Given the values for x, y, z and r we can compute the proportionality constant and determine the value of x for any value of y, z or r
x = 16 when y = 3, z = 12 and r = 3
[tex]16 = k\cdot \frac{3\cdot 12}{3^2} \\\\16 = k\cdot \frac{3\cdot 12}{9}\\\\16 = k\cdot4\\\\k = 16/4 = 4\\[/tex]
So the constant of proportionality is k = 4. Us this value in the proportionality equation along with y, z and r to get the value of x
[tex]x = 4\cdot \frac{5\cdot 30}{10 \cdot 10}\\\\x = 4\cdot\frac{150}{100}\\\\x = \frac{600}{100} = 6\\\\[/tex]
So x = 6 is the answer

Georgie spends $160 on clothes. She pays 6.5% in tax. How much does she spend altogether?
The correct answer is $170.4
Explanation:
The total Georgie spent is equal to the money spent on clothes ($160) added to taxes (6.5% of the price of the clothes). Now, to calculate the money spend on taxes follow this process:
1. Divide the total of money spent on clothes into 100 (this number represents 100%)
160 ÷ 100 = 1.6
2. Multiply this number by the specific percentage (6.5)
1.6 x 6.5 = $10.4 (This is the money spent on taxes)
Finally, add the value of taxes and the price of the clothes:
$160 + $10.4 = $170.4
