Step-by-step explanation:
QUESTION 1
The given functions are;
and 


We regroup like terms to obtain;

This simplifies to;

The correct answer is A.
QUESTION 2
The given functions are;
and
.

This implies that;


The correct answer is B.
QUESTION 3
The given functions are
and
.


We factor to obtain;

We cancel the common factors to obtain;

The correct answer is A.
Divide 132 by 8. You will get the quotient of 16 and the remainder of 4. So each row has 16 projects. The remaining 4 projects cannot be filled completely in a row.
Answer: 282.74334
Step-by-step explanation:
formula: pi • radius squared • height
To solve this problem, we are going to set up an equation. However, first we need to convert the percentages to decimals by dividing by 100.
15% = 0.15 , 7.5% = 0.075
Now, we should substitute in our given information into our equation and let our unknown value be equal to the variable x.
0.15(500) = 0.075x
Then, we should simplify our equation by multiplying together the two factors on the left side of the equation.
75 = 0.075x
Finally, we should divide both sides of the equation by 0.075 to get the variable x alone.
x = 1000
Therefore, your answer is 1000.
Hope this helps!
