Answer:
y = 7/5x + 4
Step-by-step explanation:
use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.
(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4

Its 150 cause V is 1/3*Area*height
Answer:
Step-by-step explanation:
It is assumed the interest is simple.
<u>Use the interest formula:</u>
<u>We have:</u>
- I = 13200
- P = 24000
- r = 11% = 0.11
<u>Substitute values and solve for t:</u>
- 13200 = 24000*0.11t
- 13200 = 2640t
- t = 13200/2640
- t = 5 years
