Supplementary angles measure 180°. Make an equation:
Subtract 28 to leave the variable in the parentheses alone:
Add the 2 x's together:
Your new equation is:
Divide both sides by 2 to leave the variable alone
The supplement measures 76°
Answer:
8.31
Step-by-step explanation:
Using the Pythagorean Theorem:






The side length for
, rounded to the nearest hundredths, would be 8.31.
Answer:
4
Step-by-step explanation:
Equation:
1/2x + 10 = 12
Subtract 10 from both sides:
1/2x = 2
Divide by 1/2 from both sides:
x = 4

Answer:
0.0221 feet per minute.
Step-by-step explanation:

If the Base Diameter = Height of the Cone
The radius of the Cone = h/2
Therefore,

Rate of Change of the Volume, 
Since gravel is being dumped from a conveyor belt at a rate of 10 cubic feet per minute. Therefore, the Volume of the cone is increasing at a rate of 10 cubic feet per minute.

We want to determine how fast is the height of the pile is increasing when the pile is 24 feet high.
We have:

When the pile is 24 feet high, the height of the pile is increasing at a rate of 0.0221 feet per minute.
Answer:
The partial fraction decomposition is
.
Step-by-step explanation:
Partial-fraction decomposition is the process of starting with the simplified answer and taking it back apart, of "decomposing" the final expression into its initial polynomial fractions.
To find the partial fraction decomposition of
:
First, the form of the partial fraction decomposition is

Write the right-hand side as a single fraction:

The denominators are equal, so we require the equality of the numerators:

Expand the right-hand side:

The coefficients near the like terms should be equal, so the following system is obtained:

Solving this system, we get that
.
Therefore,
