Answer:
81
Step-by-step explanation:
subtract 3 from both sides->x^1/4=-3
set both sides to the power of 4-> x=(-3)^4
solve-> x=81
Try this option:
A. f(4)=7 - false; explanation: x=4, it means that x>0 and x²-1=4²-1=15 ⇒ f(4)=15.
B. f(1)=0 - true; explanation: x=1, it means that x>0 and x²-1=1-1=0.
C. f(-1)=2 - true; explanation: x=-1, it means that x<0 and -x+1=1+1=2.
D. f(-2)=0 - false; explanation: x=-2, it means that x<0 and -x+1=2+1=3 ⇒ f(-2)=3.
Answer:
the answer is A
Step-by-step explanation:
Answer: The answer is D
Step-by-step explanation: It is the only option that makes sense to me.
If we know just two sides of a triangle, we can find<span> the </span>measure<span> of the</span>angles<span>. Step 1: Choose which trig </span>ratio<span> to use. We need to determine how the two sides we know the length of are related to </span>angle<span> A. The 4 in. side is adjacent to A and the 7 in.</span>
