Step-by-step explanation:
The functions are:
(a), (c), (d), (e).
Relations may or may not represent a function.
The relations that are functions are (a), (c), (d), (e)
Graph (a) shows a linear relationship, and all linear relations are functions.
Graph (b) fails the vertical line test, because an x value corresponds to multiple y values; so graph (b) is not a function.
Similarly, ordered pair (f) is not a function because an x value corresponds to multiple y values
Other relations (c), (d) and (e) are functions

Answer:
m<F = 79 degrees
Step-by-step explanation:
As per the given information;
m<E = 22, the triangle EDF (the one that is given in the picture) is isosceles (meaning that the sides are congruent).
In an isosceles triangle, (a triangle where the sides are congruent) the base angles (the angles opposite to the two congruent sides) are also congruent. One should also know, that in an isosceles triangle, like in any triangle, the sum of the measures of the angles equals 180 degrees.
Using this we can say that
m<D = m<F
To keep it simple while solving the problem, let's say that they have a value of x degrees.
So,
m<E + m<D + m<F =180
Subsitute
22 + x + x = 180
Simplify and inverse operations
22 + x + x = 180
-22 -22
2x = 158
/2 /2
x = 79
So the measure of <D and <F is 79 degrees.
Answer:
79
Step-by-step explanation:
An acute triangle adds up to 180
subtract 22 from 180
180-22 = 158
divide by 2
158/2 = 79

After 3 months of living at her new apartment, Renae had 1 dog. Eight months later, Renae still had 1 dog. Which of the graphs below models Renae's dog population?
Answers
Answer:
The graph would need to go through the coordinates (0, 1) and (8, 1) instead of (1, 0) and (1, 8); we would plot the population on the y (dependent) axis and time on the x (independent) axis.
The diagram shows a circle and an equilateral triangle. One side of the equilateral triangle is a diameter of the circle. The circle has a circumference of 48cm. Work out the area of the triangle.
Answers
Answer:
[tex] Area = 101.4 cm^2 [/tex] (3 S.F)
Step-by-step explanation:
Diameter of circle (D) = one side of the equilateral ∆
Circumference of the circle = πD = 48 cm
Thus:
πD = 48
Divide both sides by π
D = [tex] \frac{48}{\pi} [/tex] = 15.3 cm (approximated to nearest tenth)
Since all sides an equilateral ∆ are equal, therefore, and the diameter, D, of the circle given is the same as the length of one side of the ∆, therefore, all sides of the equilateral triangle would be 15.3 cm.
Recall that the area of a triangle can be found if we know lengths of the two sides of the ∆ and the measure of the included angle between both sides.
Since an equilateral ∆ has equal angles, each measuring 60°, then we already have all the information needed to calculate the area of the ∆.
Thus:
Length of the two sides = 15.3 cm and
15.3 cm
Included angle = 60°
Use the following formula:
[tex] Area = \frac{1}{2}ab \times Sin(C) [/tex]
Where,
a = 15.3 cm
b = 15.3 cm
C = 60°
Plug the values into the formula to find the area.
[tex] Area = \frac{1}{2} \times 15.3 \times 15.3 \times Sin(60) [/tex]
[tex] Area = \frac{1 \times 15.3 \times 15.3 \times Sin(60)}{2} [/tex]
[tex] Area = 101.4 cm^2 [/tex] (3 S.F)
The price of a DVD player is $7500.If a sales tax of 8% is charged,find the price at which the DVD player is sold
Answers
Answer:
It will be sold at $8,100.00
Step-by-step explanation:
Frist, you will have to find 8% of 7500, which is $600. Then, taxes are normally added to the original price, so $7500 + $600. This will give you the answer above.
In the following diagram it is know that AC≅BC, DE⊥AD, and m∠C=106°. Using this information find m∠E.
Answers
Answer:
Angle E is 53 degrees.
Step-by-step explanation:
Let's start with the ABC triangle first.
Since AC=BC, angle A and angle B are equal.
We know that the interior angles of a triangle add up to 180.
106 + A + B = 180
A + B = 74
A = B = 37
Moving on to the BDE triangle.
We have angle B = 37 (it's an opposite angle).
We know that angle D is 90, since this is a right triangle.
90 + 37 + E = 180
E = 53

Husky Shipping Company charges a flat rate of $150 plus $0.60 per pound to transport freight in the metro area. This cost is represented by the function below where w is the weight of the freight in pounds and c(w) is the cost given the weight of the freight. How much does Ferdinand Freight Company charge to transport freight weighing 1,500 pounds?
Answers
Answer:
Total cost = $1,050
Total cost = Fixed charges + Variable charges[Total weight]
Step-by-step explanation:
Given:
Fixed charges = $150
Variable charges = $0.60
Total weight = 1,500 pound
Find:
Total cost
Computation:
Total cost = Fixed charges + Variable charges[Total weight]
Total cost = 150 + 0.60[1,500]
Total cost = 150 + 900
Total cost = $1,050

Eighteen more than five times a number is 153. What is the number?
Answers
Answer:
[tex]\huge\boxed{\texttt{The number is 27.}}[/tex]
Step-by-step explanation:
In order to find the number we need to set up an equation where we represent the unknown number as a variable. I'll call it [tex]n[/tex].
5 times a number can be represented as [tex]5n[/tex].
18 more than that can be represented as [tex]5n+18[/tex].
We know it equals 153, so [tex]5n+18=153[/tex].
We can solve for n by reversing the equation until we have n isolated on one side.
Subtract 18 from both sides:
[tex]5n=135[/tex]
Divide both sides by 5:
[tex]n = 27[/tex]
So our unknown number is 27.
