Answer:

D) a 13% decrease in value each year

Step-by-step explanation:

Perry used the formula V (t) = 24,450(1-0.13)^t to find the value of his car t years after he purchased it.

What does 0.13 represent?

The expression given above represents and expression of exponential decrease.

This is represented by the formula

y = a(1 - r)^t

Where

y = Value after time t

a = Initial value

r = Rate of decrease

t = Time

Comparing both expressions

y = a(1 - r)^t = V (t) = 24,450(1-0.13)^t

We can see that:

r = 0.13

This is the rate of decrease.

Converting to Percentage = 0.13 × 100

= 13%

Option D is the correct option.

Find the x-value for point C such that AC and BC from a 2:3 ratio.

Galina-37 [17]

Given:

Point C divides AB such that AC:BC=2:3.

To find:

The x-value for point C.

Solution:

Section formula: If a point divide a line segment in m:n, then

$Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)$

Form the given graph it is clear that the endpoints of the line segment AB are A(-3,5) and B(3,0).

Point C divides AB such that AC:BC=2:3. Using section formula, the coordinates of point C are

$C=\left(\dfrac{2(3)+3(-3)}{2+3},\dfrac{2(0)+3(5)}{2+3}\right)$

$C=\left(\dfrac{6-9}{5},\dfrac{0+15}{5}\right)$

$C=\left(\dfrac{-3}{5},\dfrac{15}{5}\right)$

$C=\left(-0.6,3\right)$

The x-value of C is -0.6.

Therefore, the correct option is B.

Which equation represents the line that passes through the points (-4,4) and (8,-2)?

Helen [10]

Answer:

$y=-\frac{1}{2} x +2$

Step-by-step explanation:

$m=\frac{y2-y1}{x2-x1} = \frac{-2-4}{8-(-4)} =\frac{-6}{12} = -\frac{1}{2}$

So for a movement along the x-axis left to right by 2 the y-axis drops by 1

This the equation at this point is =

$y=-\frac{1}{2} x+c$

Pick any of the two points (x,y) . let's choose ( 8 , -2 )

$y2=-\frac{1}{2} x2+c \\\\..\\\\-2=(-\frac{1}{2} )(8)+c\\-2=-4+c\\\\..\\\\c=2$

SO ..

$y=-\frac{1}{2} x+2$

The lunch lady has 3 pounds of lasagna. If she makes 1/6 pound servings using this amount of lasagna, how many servings can she

Burka [1]

Answer:

She can make 18 servings.

Step-by-step explanation:

We can simply multiply 3 by 6 to get the number of servings.

This is the same as dividing 3 by 1/6 since dividing is the same as multiplying the reciprocal.
