Answer:
1: 64π
2: 49π and 153.86
Step-by-step explanation:
For the first one we know that it has a diameter of 16 which means it has a radius of 8 (half the diameter)
To find the area of a circle use the following formula
π*r² where r is the radius
This means that the first answer is π*8^2
which is 64π
For the second one it's the same deal but the radius is 7
so the answer is 49π
Answer:
Step-by-step explanation:
1 Solve:
8r + 4 = 10 + 2r
We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation
8r - 2r = 10-4
6r = 6
r= 6/6 = 1
2 Solve:
-2(x + 3) = 4x - 3
-2x -6 = 4x - 3
We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation
-2x - 4x = -3 + 6
-6x = 3
x = 3/-6
x = -1/2
3 Solve
5 + 3(q - 4) = 2(q + 1)
5 + 3q - 12= 2q+2
We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation
3q - 2q = 2 +12 - 5
q = 9
4. Solve
7x - 4 = -2x + 1 + 9x - 5
We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation
7x +2x-9x = 1 - 5 +4
0= 0
5 Solve:
8x + 6 - 9x = 2 - x -15
We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation
8x -9x + x = 2 - 15 -6
0x = -19
0= 19

Answer:
A. -1 ≤ x ≤ 3
Step-by-step explanation:
The range is the horizontal extent of the graph--the set of x-values for which the function is defined. Here, the graph extends from x = -1 to x = 3, with both end points included. The range is ...
-1 ≤ x ≤ 3
