Answer:
334 in^2.
Step-by-step explanation:
The surface area = area of the top prism + area of the bottom - 2 * area of the base of the top smaller prism
= 2(5*3 + 5*3 + 3*3) + 2(9*7 + 9*5 + 7*5) - 2* 3*5
= 2* 39 + 2*143 - 30
= 334
Rate of change means (change)/time elapsed
change=5700 to 7945
7945-5700=2245
time elapsed is from 1998 to 2005 which is 7 years
rate=2245/7yrs=320 and 5/7 people per year
Answer:
4.84% of trees on the island are poisonous.
Step-by-step explanation:
The proportion of fruit trees that are poisonous is the number of poisonous fruit trees divided by the total number of trees.
The percentage is the proportion multiplied by 100.
In this question:
60 poisonous trees.
1240 total trees.
60/1240 = 0.0484
0.0484*100 = 4.84%
4.84% of trees on the island are poisonous.

Answer:
C(-1) = -5.
Step-by-step explanation:
C(x) = -4x² + 4x + 3
Plug in -1 for x to solve for C(-1):
C(-1) = -4(-1)² + 4(-1) + 3
Simplify:
C(-1) = -4 + (-4) + 3
C(-1) = -5
