Answer:

$19500

Step-by-step explanation:

Let the depreciation rate is x per year, then we have:

28000*x² = 22000
x² = 22000/28000
x² = 0.7857
x = √0.7857
x = 0.8864

Exponential function for this case is:

V(t) = 28000*0.8864^t, where V(t) - future value, t- number of years

Value of the car after 3 years:

V(3) = 28000*0.8864^3
V(3) = 19500

Find the slope of the line passing through (-2,5) and (9,-7)?

Marat540 [252]

Use the slope formula.
Y2 - Y1 / X2 - X1
(-7 - 5) / (9 - -2)
(-12) / (11)
So answer: slope(m) = -12/11

Which number sentence is true?

Alexxx [7]

Answer:

The answer is B

Step-by-step explanation:

Because A is incorrect because the -8.9 is in absolute value which mean it will be an 8.9 which is greater than 5.6

C is Incorrect because - 5.6 is not greater than the absolute value of -8.9 which is 8.9, as you can see is greater than -5.6

D is incorrect because the absolute value of 5.6 is still 5.6 and the absolute value of - 8.9 is 8.9 which is greater that 5.6

<h2>B is correct because the absolute value of -5.6 is 5.6 which makes it less than the absolute value of -8.9 because the absolute value is 8.9 which is greater than 5.6 .</h2>

What is the equation of the line? Plsss helppp

Goshia [24]

Answer:

y = -7

Step-by-step explanation:

Slope: 0

y-intercept: (0,−7)

Since the line doesn't change up, down, right, or left, and it stays on the y-axis, that's how u get y = . The straight line runs along -7 . That's how u get -7 . so when u put it all together u get: y = -7 .

Hope that helps. Tried to explain the best I could :)

in the figures below the cube shaped box is 6 inches wide and the rectangular box is 10 inches long 4 inches wide and 4 inches h

IRINA_888 [86]

The cube’s sides measures 6 inches and the measurement for the rectangular box is that it is 10 inches long, 4 inches thick and 4 inches high. To compute for the volume of a cube you must use the formula of V = a3 and for the rectangular prism is V = l x w x h.
Cube: V = 6^3
 V = 216 inches^3
Rectangular Prism: V = 10 x 4 x 4 
 V = 160 inches^3
To identify how much greater the volume the cube from the rectangular box we subtract their volumes.
N = C – R where N stands for the unknown C for the volume of cube and R for the volume of Rectangular Box 
N = 216 inches^3 – 160 inches^3
 N = 56 inches^3 
So the cube is 56 inches3 greater than the rectangular box.
