Answer:
The solution is (0, 2).
Step-by-step explanation:
Here we have two different equations for y. Equate them to eliminate y. Solve the resulting equation for x:
y = −1/3x + 2 = y = x + 2
Simplifying, we get (-1/3)x = x, and so x must be 0.
Then, using the second equation, we find that y = 0 + 2 = 2.
The solution is (0, 2).
Answer: It will take him 1.68 years to recover his initial investment.
First, find the amount of extra money that he will make.
34,000 - 13,000 = 21,000
He will be making an extra 21,000 per year.
Now, divide the cost of his training by the amount of his increase.
35200 / 21000 = 1.68
That gives you the amount of years it will take him to pay off his investment.
Step-by-step explanation:
TSA of cylinder = 2πr (h + r)
according to the question
height = radius
then,
TSA = 2πr (r + r)
2464=2 × 3.1415×r ×2r
2464/4 ×3.1415 = r×r
196.08 = r^2
r = 14.00
r = 1 4 cm
We know,
volume = 2πr ^2 ×h
=2×3.1415×14×14×14 (h=r)
=17240.552 cm^3
