Answer:
Step-by-step explanation:
You do not need to where the formula comes from but, just for fun, here’s a hint
To add up the numbers 1 to 10
Write out the numbers
1 2 3 4 5 6 7 8 9 10
Write them backwards
10 9 8 7 6 5 4 3 2 1
Add up both lists
11 11 11 11 11 11 11 11 11 11
This is 10 × 11 = 110
But this is twice the sum as two lots were added together
So the sum of the numbers 1 to 10 is 110 ÷ 2 = 55

Answer:
64π^2 cubic inches
Step-by-step explanation:
The question is not complete, the shapes are not given
Diameter of base= 16π
Radius of base= 8π
Height of cylinder = 8 inches
Let us find the volume of the cylinder
V= πr^2h
V= π* (8π)* 8
V= 64π^2 cubic inches
Hence the volume of the cylinder is 64π^2 cubic inches
Assuming that the figure is implying that angles 1 and 2 are the same, we have
So, the measure of angles 1 is
Answer:
74
Step-by-step explanation:
fg(x)=f[g(x)]
=f(-4x+7)
=3(-4x+7)+5
=-12x+26
When x=-4,
fg(-4)=-12(-4)+26
=74
