Answer:
The smallest integer is -4.
Step-by-step explanation:
4(n + n+2) = 3*n - 12 Combine the left
4(2n + 2) = 3n- 12 Remove the brackets
8n + 8 = 3n - 12 Subtract 3n from both sides
8n-3n + 8 = 3n-3n - 12 Combine
5n + 8 = - 12 Subtract 8 from both sides
5n = - 12 - 8
5n = - 20 Divide by 5
5n/5 = -20/5
n = - 4
n + 1 = -3
n + 2 = - 2
Answer:
this answer requires that you do a little solving to find all the dimensions we need for the volume.
We know that H (height) = 2m
Diameter = 5 x height, so
Diameter = 5 x 2m = 10m
If you have the formula for finding the volume of a cylinder, it is basically the area of the circular base x cylinder height. You may know already that the area of a circle is (pi) x radius2
So this will be 2 (the height) x (pi) x r2
As we just figured out, the DIAMETER is 10, so the radius is half the diameter = 5.
This brings our volume to 2 x (pi) x 52
= 2 x (pi) x 25
2x25 = 50, so we have 50 x (pi).
Pi = 3.14
50 x 3.14 = 157
And don't forget your units = 157 m3

Answer:
a) f(-1) = 1
b) f(0) = 6
c) f(2) = 8
Step-by-step explanation:
If x is lesser than 0, we have that:
f(x) = 4x + 5
Otherwhise
f(x) = x + 6
(a) f(-1)
Here x = -1.
-1 is lesser than 0
Then
f(x) = 4x + 5
f(-1) = 4*(-1) + 5 = -4 + 5 = 1
(b) f(0)
Here x = 0
When x equals 0
f(x) = x + 6
Then
f(0) = 0 + 6 = 6
(c) f(2)
Here x = 2
When x = 2
f(x) = x + 6
Then
f(2) = 2 + 6 = 8
