Answers

For the question "A movie rental store charges a membership fee of $10.00 plus $1.50 per movie rented. What is a possible domain that shows the cost to a member of renting movies?" The correct answer is "The domain is all integers 0 or greater."This is because the equation that models the cost to a member of renting movies is given by y = 10 + 1.5x, where x is the number of movies rented.The domain of a function are the value the independent variable can take, in this case, the values x can take.Each member of the movie rental store has an option of renting from 0, 1, 2, 3, . . . number of movies.

Answer:

B) The domain is all integers 0 or greater.

The vertex of this parabola is at (-3, 6). Which of the following could be its equation? A. y = -3(x + 3)2 + 6
B. y = -3(x + 3)2 - 6
C. y = -3(x - 3)2 + 6
D. y = -3(x - 3)2 - 6

Answers

Based on the calculations, the equation of this parabola is equal to: A. y = -3(x + 3)² + 6.

How to determine the equation of a parabola?

Mathematically, the standard equation with the vertex for any parabola is given by:

y = a(x - h)² + k.

where:

  • h and k are the vertex.
  • a is a point.

Substituting the given parameters into the formula, we have;

y = -3(-3 - (-3))² + 6

y = -3(x + 3)² + 6

Hello,

A is your answer

(-3,6) must be a point of the curve.

A) if x=-3 then y=-3(-3+3)²+6=6
y'=-3(x+3)=0==>x=-3
and y=6

B) if x=-3 then y=-3(-3+3)²-6=-6 and not 6
 
C) if x=-3 then y=-3(-3-3)²+6=-3*36+6= -102 and not 6

D) -3(-3-3)²-6=-3*36-6=-114

The model y = 500(1.035)^x, indicates the value of an investment, where x is the number of whole years. What's the growth factor (the ratio from one year to the next)?

Answers

Given:
model y = 500(1.035)^x is the value of the an investment after x years.

the growth factor of this model is 1.035

Let us assume that x = 3 and x = 2

y = 500(1.035)² = 500 (1.07) = 535
y = 500(1.035)³ = 500 (1.11) = 555

growth factor = 555 / 535 = 1.037 or 1.035

if its length is 2x-3 feet and its width is 5x+1 feet, what is the actual length and width of the rectangle ? ( a rectangle has an area of 1281 square feet.)

Answers

( 2x - 3) X ( 5x +1) = 1281

*it's a quadratic

10x² -13x -3 = 1281  * move 1281 to the left side to equal zero

10x² -13x - 1284= 0
 

and solve to look for the zeros....
