Answer:
2,4,6,8 is an arithmetic sequence because you are adding 2 but the second step it's the same but you are subtracting 2
Step-by-step explanation:
The third one is so wrong.
Answer:
162 m^2
Step-by-step explanation:
Tops:
The area of the high top is 3*2 = 6
The area of the lower top is 5*2 = 10
--------
16
Bottom:
The area of the bottom is 8*2 =16
Back:
The area of the back is 2*11 = 22
Front:
The top front is 9*2 =18
The bottom front is 2*2 =4
-------------------------------------------
22
Sides
The area of the left side is
vertical piece 11*3 =33
horizontal piece 5*2 = 10
-------------
43
The right side is the same = 33+10 = 43
Add them together
top+bottom+ back+front+left+right
16+16+22+22+43+43 =162 m^2
Answer:
6.816. But if you want to round up then 7

Answer:
See below for answers and explanations
Step-by-step explanation:
<u>Part A:</u>
f(x) = -x² + 4x - 10
f(2) = -(2)² + 4(2) - 10
f(2) = -4 + 8 - 10
f(2) = 4 - 10
f(2) = -6
<u>Part B:</u>
g(x) = 5x + 1
g(6) = 5(6) + 1
g(6) = 30 + 1
g(6) = 31
<u>Part C:</u>
f(x) = -x² + 4x - 10
f(-1) = -(-1)² + 4(-1) - 10
f(-1) = -1 - 4 - 10
f(-1) = -5 - 10
f(-1) = -15
<u>Part D:</u>
g(x) = 5x + 1
16 = 5x + 1
15 = 5x
3 = x
x = 3
The answer is 155 because 124/4 is 31 so the average rate of change is 31 so multiply by 5 and it gives you 155
