Answer:
A) d(r) = 2r
Value when r = 5 is 10 ft.
diameter is 10 ft when the radius is 5ft
B) A(r) = πr²
Value when r = 5 is 25π ft²
Area is 25π ft² when radius is 5 feet
C) C(r) = 2πr
Value when r = 5 is 10π
Circumference is 10π when radius is 5 feet
Step-by-step explanation:
A) Using function notation, since d = 2r
d(r) = 2r
d(5) = 2(5)
d(5) = 10 feet
This means that the diameter is 10 ft when the radius is 5ft
B) Area = πr²
In function notation, its;
A(r) = πr²
When radius is 5 feet,
Area is; A(5) = π(5²) = 25π
It means Area is 25π ft² when radius is 5 feet
C) Circumference is 2πr
In function notation, it's;
C(r) = 2πr
When r = 5 feet,
Circumference is;
C(5) = 2π(5)
C(5) = 10π

Step-by-step explanation:
The scale on the map is 1 centimeter is equal to 25 kilometers. On the map, the distance the towns along the highway is 4.5 centimeters. Tori's car uses 0.123 liter of gasoline for each kilometer of highway driving. How many liters of gasoline to the nearest liter will Tori need to drive from one of these town to the other?
Answer: About 14 liters of gasoline is required.
Step-by-step explanation:
On the map,
1 centimeter= 25 kilometers.
Distance the towns along the highway is 4.5 centimeters.
Actual distance = 4.5 x 25 km
= 112.5 km
Tori's car uses 0.123 liter of gasoline for each kilometer of highway driving.
Total gasoline required = 0.123 x 112.5 km
= 13.8375 liters≈ 14 liters
hence, about 14 liters of gasoline is required.

Margaret drank 1/6 of a 36oz. Bottle of soda. She gives the rest of the bottle to her friend Jamie who drinks 2/3 of the soda in the bottle. Jamie then gives the rest of the bottle to her friend Taylor. How much soda is left in the bottle when Taylor gets it? Group of answer choices
Answer:
The amount of soda that is left in the bottle when Taylor get it is 1/6 = 6 oz of soda.
Step-by-step explanation:
Let the total quantity of soda left in the bottle be represented by 1
Total quantity of the bottle = Fraction of what( Margaret + Jamie + Taylor) drank
Margaret drank = 1/6 of the soda
= 1 - 1/6
= 5/6 of soda is left
Jamie drank = 2/3 of what is left
= 5/6 - 2/3
LCM of denominators = 6
= 5 - 4/6
= 1/6
Hence, what is left is 1/6 of the soda.
The size of the soda = 36 oz
1/6 × 36oz
= 6 oz
This means the amount of soda that is left in the bottle when Taylor get it is 6 oz of soda.

Let f(x)=x²-x-12 and g(x)= x -4.
What value can the expression (f/g)(x) never equal?
Answer:
7
Step-by-step explanation:
This function can never equal 0. Why? well here:
(f/g)(x) also just means [tex]\frac{f(x)}{g(x)}[/tex]. In this case, we get [tex]\frac{x^2-x-12}{x-4}[/tex] Or [tex]\frac{(x+3)(x-4)}{x-4}[/tex]. It seems like you can cancel out x-4 and bam, you get x+3 and any value should work.
However, x can never equal 4 because 4 leads to a case where you divide by 0. This is called discontinuity. Thus, the value you can't get is x=4, or 7 because when you plug 4 in, you get 0/0. Otherwise, any other real value is defined by x+3.

A journalist is assigned to write a story that is 1,200 words long. To fit in the publications available space, the story's length can vary by no more than 75 words.
which word counts would be accepted by the journalist's publication?
1,100 1,125 1,290 1,260 1,300
The word count that can be accepted by the journalist's publication is 1,260.
Given,
A journalist is assigned to write a story that is 1,200 words long.
To fit in the publication's available space, the story's length can vary by no more than 75 words.
We need to find which word counts would be accepted by the journalist's publication.
1,100, 1,125, 1,290, 1,260, 1,300
Find the number of words the publication accepts.
We have,
1,200 words long.
The story's length can vary by no more than 75 words.
So,
1,200 + 75 = 1,275 words
The words can vary from 1,200 to 1,275 words.
Find the option which can be accepted.
1,100 - can not be accepted
1,125 - can not be accepted
1,290 - can not be accepted
1,260 - can be accepted
1,300 - can not be accepted
Thus the word count that can be accepted by the journalist's publication is 1,260.

-11x - 7y = -56, solve for y (must be in form y = mx + b)
Answer:
y= -11/7x+8
move variables to the right hand side and change its sign
-7y=-56+11x
change the signs on both sides of the equation
7y=56-11x
divide both sides by 7
y=8-11/7 x
reorder the terms and get y= -11/7x+8
