I've asked this question twice and gotten 2 different answers. this is sooo urgent and I don't know what the right answer is. A long-distance phone company charges $4.95 month plus an additional $.10 per minute. a. Define a variable and write a formula to find the total cost per month for long-distance service. b. Use this formula to find the long-distance charges for 120 minutes of calls in one month.
Answer:
C=4.95 +0.10x, where x=minutes
C=4.95 + 120(0.10)
C=4.95 +12.00=$16.95
Hope this helps!!

ΔABC is similar to ΔFED. Answer the questions to find the length of DF .
1. Which side in ΔFED does AB in ΔABC correspond to?
Write your answer in the space below.
2. Which side in ΔFED does CB in ΔABC correspond to?
Step-by-step explanation:
ΔABC is similar to ΔFED.
AB are the first 2 letters in ΔABC. Similarly, FE are the first 2 letters in ΔFED.
Hence side AB corresponds to side FE.
CB are the last 2 letters in ΔABC. Similarly, DE are the last 2 letters in ΔFED.
Hence side CB corresponds to side DE.
Answer:
1. EF in ΔFED corresponds to AB in ΔABC.
2. DE in ΔFED corresponds to CB in ΔABC.
3. The length of DF is 10.
Step-by-step explanation:
Given: ΔABC is similar to ΔFED. Find the length of DF.
To Find: The length of side DF in ΔFED
Since, ΔFED is a right-angled triangle and also similar to ΔABC,
Applying similarity of triangles principle,
AB = 4 , EF = 8
BC = 3 , DE = 6
Now, applying Pythagorean theorem on ΔFED,
Hypotenuse² = Length² + Base²
⇒ DF² = DE² + EF²
⇒ DF² = 6² + 8²
⇒ DF² = 100
⇒ DF = √100
⇒ DF = 10
Final Answer: Hence the length of side DF is 10.

Which isa zero of the quadratic function f(x) = 4x + 24x + 11?
Ox=9.25
Ox=-5.5
Ox=0.5
Ox=3.25
Answer:
b
Step-by-step explanation:
just took the test edg 22
Option B is correct, -5.5 is the zero of the quadratic function f(x) = 4x + 24x + 11
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The given quadratic function is f(x) = 4x²+24x+11
We have to find the zero of the function.
Let us use the quadratic formula to find the zero.
a=4, b=24 and c=11
Let us plug in these values in quadratic formula
x=- 24±√24²-4(4)(11)/8
=-24±√576-176/8
=-24±√400/8
=-24±20/8
=4(-6±5)/8
=(-6+5)/2 or -6-5/2
=-1/2 or -11/2
=-0.5 or -5.5
Hence, Option B is correct, -5.5 is the zero of the quadratic function f(x) = 4x + 24x + 11

A plumber charges $65 to make a house call plus an additional charge of $42 per hour for labor. Write an equation to represent the total cost (y) for any number of hours (x).
Answer:
the required equation to represent the total cost with respect to every hour will be
=》y = 42x + 65
Step-by-step explanation:
total cost (y) = charge to make a house call + additional charge for every our
so, total additional charge for x hours
= 42 × x = 42x
hence y = 65 + 42x ( where 65 is charge to make a house call , y is total cost and 42x is additional charge for x hours )

Dione is designing a water fountain for the lobby of a new hospital. She knows that the fountain will have a circular pool with water projected upward at a constant rate from the center of the pool. She needs to determine the maximum height, so she uses a linear model to represent the situation.
Answer:
Diane did not choose a good model. Because the water is a projectile with a maximum height, she should use a quadratic model
Step-by-step explanation:
Here, we want to choose the correct option
As we are having a circular projection, we should be looking at having a parabolic representation i.e a model that looks like a parabola
So the correct answer in this case is that;
Diane did not choose a good model. Because the water is a projectile with a maximum height, she should use a quadratic model

7. A city lot is twice as long as it is wide, If its perimeter is 480 units, what are the dimensions of the lot?
Answer:
Step-by-step explanation:
P = 480
P = 2 length + 2 width
but we also know that
2width = length
so plug that into the length
P = 2(2width) + 2 width
480 = 4 width + 2 width
480 = 6 width
80 = width
160= length
