So find the area of each shape and add them.
30+30+30+30+36=156
Triangle A= 1/2xLxH
Square A= LxH
Answer:
B. -5 - 1/8
Step-by-step explanation:
(-1/2) * 10 = -5
(-1/2) * 1/4 = -1/8
(-1/2)(10 + 1/4) = -5 - 1/8
Answer:
(9/2, 9/2)
Step-by-step explanation:
midpoint formula = (x1 + x2/2, y1 + y2/2)
(7,6) is x1 and y1.
(2,3) is x2 and y2.
Solve:
x-coordinate= (7+2)/2 = 9/2 or 4.5
y-coordinate= (6+3)/2 = 9/2 or 4.5
your final answer is (9/2, 9/2)
decimal form = (4.5, 4.5)
Answer:
0
Step-by-step explanation:
The power is 0 since 2^0 = 1.
Answer:
A) ![V =12500[1-\frac{17.2 \times t}{100} ]](https://tex.z-dn.net/?f=V%20%3D12500%5B1-%5Cfrac%7B17.2%20%5Ctimes%20t%7D%7B100%7D%20%5D)
B) ![V = 12500[1-\frac{19}{100} ]^{t}](https://tex.z-dn.net/?f=V%20%3D%2012500%5B1-%5Cfrac%7B19%7D%7B100%7D%20%5D%5E%7Bt%7D)
Step-by-step explanation:
In two years i.e. from 2013 to 2015 the car value decreases from $12500 to $8200.
a) If the rate of decrease is constant and it is r% per year, then
![8200 = 12500[1-\frac{r \times 2}{100}}]](https://tex.z-dn.net/?f=8200%20%3D%2012500%5B1-%5Cfrac%7Br%20%5Ctimes%202%7D%7B100%7D%7D%5D)
⇒ r = 17.2%
Therefore, the value of the car is given by , where, t is in years since 2013. (Answer)
b) If the rate of decrease is exponential and it is r%, then
![8200 = 12500[1-\frac{r}{100} ]^{2}](https://tex.z-dn.net/?f=8200%20%3D%2012500%5B1-%5Cfrac%7Br%7D%7B100%7D%20%5D%5E%7B2%7D)
⇒ r = 19%
Therefore, the value of the car is given by , where, t is in years since 2013. (Answer)
