A. 8^9/2= around 11585.2375; (sqrt8)^9= around 11585.2375. So choice A shows a pair of equivalent expressions.
B. (3sqrt125)^9=1,953,125; 125^9/3=1,953,125. So choice B also shows a pair of equivalent expressions.
C. 12^2/7= around 2.03394; (sqrt12)^7= around 5,985.96759. So choice C does not show a pair of equivalent expressions.
D. 4^1/5=around 1.31951; (sqrt4)^5=32. So choice D also doesn't show a pair of equivalent expressions.
Your answers are A and B.
I hope this helps ;)
We will solve the equation to find a zero of f(x):
The formula is:
where:
a=-1, b=-5, c =50
This is the only solution because the other is:
which is not possible.
Answer:
D) The diver hits the water 5 feet away horizontally from the board.
We know that a = b and c = 30
Since b + 30 = 90, we know b = 60.
That means a = 60
a = 60
b = 60
c = 30
The shelf should sell for $235.20.
Marking the price up by 60% means taking 160% of the cost:
160% = 160/100 = 1.6; 1.6(147) = 235.20
Answer:
Extra number = (23×20) - (19×17)
= 137
