Given problem;
A = 4 π R²
To solve for R, we have to make it the subject of the expression.
Since
A = 4 π R² , follow these steps to find R;
Multiply both sides by
A x = x 4 π R²
= R²
Then find the square root of both sides
√R² =
R =
The solution is
Answer:
c) 2 + 3 = 5 TRUE
d) 2 + (–3) = -1 True
Step-by-step explanation:
When adding integers (positive and negative whole numbers), there are three cases:
- Positive and positive increases and sum is positive. Ex. 4 + 6 = 10
- Positive and negative where you subtract and take the sign of the larger number. Ex. 3 + -8 = -5 or -3 + 8 = 5
- Negative and negative decrease and the sum if negative. Ex. -4 + -6 = -10.
Use these rules to simplify each expression.
a) 2 + (–3) = -1 not 1 FALSE
b) –3 + 2 = -1 not 5 FALSE
c) 2 + 3 = 5 TRUE
d) 2 + (–3) = -1 True
The slope of y= 1/2x-7 is always positive because since the slope of this equation is “1/2”, 1/2 is always positive.
Answer:
Step-by-step explanation:
When x=3, y = ln(3-2) = ln(1) = 0.
:::::
When x=4, y = ln(4-2) = ln(2) ≅ 0.693.
:::::
When x=6, y = ln(6-2) = ln(4) ≅ 1.386.
