Answer:
108.62ft
Step-by-step explanation:
12348=⁴/3×3.14×r²
r²=12348×¾÷3.14
r²=2,949.36
r=squareroot of 2,949.36
r=54.308
d=2r
d=54.308×2
d=108.616
The absolute value of -3 is 3 and -3 so both would be right
Answer:
Table C
Step-by-step explanation:
Given
Table A to D
Required
Which shows a proportional relationship
To do this, we make use of:

Where k is the constant of proportionality.
In table (A)
x = 2, y = 4



x = 4, y = 9



Both values of k are different. Hence, no proportional relationship
In table (B)
x = 3, y = 4



x = 9, y = 16



Both values of k are different. Hence, no proportional relationship
In table (C):
x = 4, y = 12



x = 5, y = 15



x = 6, y = 18



This shows a proportional relationship because all values of k are the same for this table
The answer is plus +3 for slope
Answer:
D(- 1) = 2
Step-by-step explanation:
To evaluate D(- 1), substitute x = - 1 into D(x) , that is
D(- 1) = (- 1)² - 2(- 1) - 1 = 1 + 2 - 1 = 2
