<u>EXPLANATION</u>
We want to solve the trigonometric equation;
, where
.
Taking square root of both sides gives,


Since B is in the first quadrant, we proceed with;
, because the tangent ratio is positive in the first quadrant.

.
Correct to the nearest degree,

Answer:
160
Step-by-step explanation:
800 gallons in 5 days. The days is the denominator and the gallons are the numerator, whatever you do the the bottom you do to the top, so you divide the denominator by 5 and the numerator by 5 and you get 160 gallons per day. If you want to know how your answer is right, multiply 160 by 5
Y=(x+3)²+(x+4)²
y=x²+6x+9+x²+8x+16
y=2x²+14x+25
y=2(x²+7x+3.5²-3.5²)+25
y=2(x+3.5)²-2*3.5² +25
y=2(x+3.5)²+0.5
