Answer:
Height+surface area of the bottom circles*2
Step-by-step explanation:
If the height was 3 and the surface areas of the circles were 6, you would end up with a surface area of 15
Answer: The average rate of change is
Step-by-step explanation:
The points (1, 2); (2, 2.5); (3, 3); (4, 3.5) and (5, 4) belong to the line shown in the graph attached.
The average rate of change for the sequence is the slope and you can calculate it with the formula:
Then, choose two points of the line and substitute them into :
Let's choose the point (1,2) and the point (2,2.5). Then:
The answer would be 2 and Reduce the expression if possible by cancelling the common factors.
Answer:
Heidi wants to compute:
17 - 9.
First, she adds to get 10, (we want to subtract 10, this is easier than subtracting 9) then she can do:
17 - 9 + 0
adding zero does not change the sum
1 - 1 = 0
then:
17 - 9 + 0 = 17 - 9 + 1 - 1
Now we can do:
17 - 9 - 1 + 1
17 - (9 + 1) + 1
17 - 10 + 1
(17 - 10) + 1
7 + 1 = 8
Then, first she needs to add -1, in order to subtract 10, and then she must add 1. As we added a number and its inverse, in total we added zero, so the sum did not change, but was easier to compute.
Then, you need
