There were 256 slices of pizza. :-)
1. N is a midpoint of the segment KL, then N has coordinates
![\left(\dfrac{x_K+x_L}{2},\dfrac{y_K+y_L}{2} \right) =\left(\dfrac{0+2a}{2},\dfrac{2b+0}{2} \right) =(a,b).](https://tex.z-dn.net/?f=%20%5Cleft%28%5Cdfrac%7Bx_K%2Bx_L%7D%7B2%7D%2C%5Cdfrac%7By_K%2By_L%7D%7B2%7D%20%5Cright%29%20%3D%5Cleft%28%5Cdfrac%7B0%2B2a%7D%7B2%7D%2C%5Cdfrac%7B2b%2B0%7D%7B2%7D%20%5Cright%29%20%3D%28a%2Cb%29.%20)
2. To find the area of △KNM, the length of the base MK is 2b, and the length of the height is a. So an expression for the area of △KNM is
![A_{KMN}=\dfrac{1}{2}\cdot \text{base}\cdot \text{height}=\dfrac{1}{2}\cdot 2b\cdot a=ab.](https://tex.z-dn.net/?f=%20A_%7BKMN%7D%3D%5Cdfrac%7B1%7D%7B2%7D%5Ccdot%20%5Ctext%7Bbase%7D%5Ccdot%20%5Ctext%7Bheight%7D%3D%5Cdfrac%7B1%7D%7B2%7D%5Ccdot%202b%5Ccdot%20a%3Dab.%20)
3. To find the area of △MNL, the length of the base ML is 2a and the length of the height is b. So an expression for the area of △MNL is
![A_{MNL}=\dfrac{1}{2}\cdot \text{base}\cdot \text{height}=\dfrac{1}{2}\cdot 2a\cdot b=ab.](https://tex.z-dn.net/?f=%20A_%7BMNL%7D%3D%5Cdfrac%7B1%7D%7B2%7D%5Ccdot%20%5Ctext%7Bbase%7D%5Ccdot%20%5Ctext%7Bheight%7D%3D%5Cdfrac%7B1%7D%7B2%7D%5Ccdot%202a%5Ccdot%20b%3Dab.%20)
4. Comparing the expressions for the areas you have that the area
is equal to the area
. This means that the segment from the midpoint of the hypotenuse of a right triangle to the opposite vertex forms two triangles with equal areas.
That's the answer
-You have to multiply each side by 2
-And then move the constant to the right
And then calculate
26-18=x
X=-8
The exponential function models the value v of the car after t years is V = 27000 * (0.93)^t
<h3>How to determine the exponential model?</h3>
The given parameters are:
Initial value, a = $27,000
Depreciation rate, r = 7%
The value of the car is then calculated as:
V = a * (1 -r)^t
Substitute known values
V = 27000 * (1 - 7%)^t
Evaluate the difference
V = 27000 * (0.93)^t
Hence, the exponential function models the value v of the car after t years is V = 27000 * (0.93)^t
