HELP PLEASE

Answer:

c $11,751

Step-by-step explanation:

The function that models Alicia's car is

$f(x) = 21000(0.93)^{x}$

where x represents the number of years since she purchased the car.

We want to find the value of Alicia's car after 8 years.

We substitute x=8 into the formula to get:

$f(8) = 21000(0.93)^{8}$

$f(8) = 21000(0.5596)$

$f(8) = 11751.218$

We round to the nearest dollar to get:

$f(8) =11751$

The correct answer is C.

Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. She also earns a base salary

Mariulka [41]

Answer: her sales last week was $4300.

Step-by-step explanation:

Let x represent her her sales in a week.

Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. This means that the commission she gets if she makes sales of $x is 0.0825x

She also earns a base salary of $675 per week. The expression for the total earnings for a week in which she made sales of $x would be

0.0825x + 675

if her total earnings for last week were $1,029.75, it means that

0.0825x + 675 = 1029.75

0.0825x = 1029.75 - 675

0.0825x = 354.75

x = 354.75/0.0825

x = $4300

Write the quadratic function in vertex form. Then identify the vertex.

ddd [48]

Answer:

Step-by-step explanation:

To put the equation into vertex form, we need to complete the square

$g(x) = (x^2 - 4x + ...) - 1\\g(x) = (x^2-4x+(\frac{4}{2})^2 ) - 1 - (\frac{4}{2})^2 \\g(x) = (x-2)^2 - 5\\$

This is in the form

$y = a(x-h)^2 + k\\(h, k)$

So, the vertex is (2, -5)

and $g(x) = (x-2)^2-5$

Write an equation in slope-intercept form for the line with slope 4 and y-intercept -5.

ArbitrLikvidat [17]

Answer:

y = 4x -5

Step-by-step explanation:

y = mx+b

m = slope

b = y-intercept

so y= 4x -5
