Answer:
![m = 324](https://tex.z-dn.net/?f=m%20%3D%20324)
Step-by-step explanation:
The average rate of change is:
![m = \frac{h(2)-h(-2)}{2 - (-2)}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7Bh%282%29-h%28-2%29%7D%7B2%20-%20%28-2%29%7D)
![h(-2) = 81\cdot (-2)^{3}-(-2)^{2}](https://tex.z-dn.net/?f=h%28-2%29%20%3D%2081%5Ccdot%20%28-2%29%5E%7B3%7D-%28-2%29%5E%7B2%7D)
![h(-2) = -652](https://tex.z-dn.net/?f=h%28-2%29%20%3D%20-652)
![h(2) = 81\cdot (2)^{3}-(2)^{2}](https://tex.z-dn.net/?f=h%282%29%20%3D%2081%5Ccdot%20%282%29%5E%7B3%7D-%282%29%5E%7B2%7D)
![h(2) = 644](https://tex.z-dn.net/?f=h%282%29%20%3D%20644)
![m = \frac{644-(-652)}{2-(-2)}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B644-%28-652%29%7D%7B2-%28-2%29%7D)
![m = 324](https://tex.z-dn.net/?f=m%20%3D%20324)
25×(1−0.18)^(4)
=11.30
25*0.01=25(1-0.18)^t
0.25=25(0.82)^t
0.25/25=(0.82)^t
t=log(0.25/25)/log(0.82)
t=log(0.25÷25)÷log(0.82)
t=23.21 hours
Answer:
4x-y=19, y=4x-19
Step-by-step explanation:
I learned a really quick way to do these in geometry.
Let's use standard form or ax+by=c.
Slope of 4: 4x - y = c.
Passes through point 6,5.
4(6) - 5 = c
c= 24-5
c=19
4x-y=19
y=4x-19
Answer:
44 in^2
Step-by-step explanation:
break it into 2 smaller rectangles and solve those.
193.5m is the area because you have to isolate the different shapes in the overall figure, and find the area of those first, once you have found them all you need to add them together
