Answer:
B
Step-by-step explanation:
put both sides under square root.
x^2 + y^2 = 64
sqrt ( x^2 + y^2 ) = sqrt(64)
x + y = 8
r = 8.
Answer:
m∡P = 40°
Step-by-step explanation:
15m + 17 + 4m - 10 + 7m - 9 = 180
26m - 2 = 180
26m = 182
m = 7
∡P = 7(7) - 9 = 49 - 9 = 40
Well if the alloy makes the 1000 grams, but you are dealing with copper that isn't even 100% copper, than you either need 55% more copper, which isn't given, which means you really need 550 grams of alloy copper.
In this case, we are given with the expression <span>sin(cos 8θ)/sec 5θ and is asked to evaluate the expression with limit as theta approaches 0. In this case, we just substitute 0 to theta. cos 0 is equal to 1 hence sec 0 is also equal to 1. sin theta is equal to 0.0175. Answer os 0.0175.</span>
