Solve the quadratic equation.<br> (a + 5)2 +36 = 9
Andrej [43]

Answer:

No solution unless you want to solve for an imaginary number which in that case a=27i-5

Step-by-step explanation:

(a+5)^{2} +36=9

(a+5)^2=-27

a+5=\sqrt{-27}

Here you can stop and say "no solution" since you cannot square root a negative number, but if you want you can still solve for an imaginary number:

a+5=\sqrt{-1} \sqrt{27}

a+5=27i

a=27i-5

Paul Kim estimates that he will drive about 10,000 miles during the year and will have $3,460 in annual fixed costs. He projects
Mama L [17]

Answer:

The maximum annual variable cost he can have to reach his projection is $1,940

Step-by-step explanation:

Given;

Number of miles drive per year N = 10,000 miles

Total annual Fixed cost F = $3,460

cost per mile(rate) r = $0.54 or less

Total cost = fixed cost + variable cost

Total cost = cost per mile × number of miles

Total cost = r × N = $0.54 × 10,000 = $5,400

Let V represent the total variable cost per year;

F + V ≤ r × N

Substituting the values;

3,460 + V ≤ 5,400

V ≤ 5,400 - 3,460

V ≤ 1,940

The maximum annual variable cost he can have to reach his projection is $1,940
