Answer:
Step-by-step explanation:
5.
12x-7
12 x 4-7
48-7=41
answer-41
6.
(4 to the power of 2 =16)
16 divided by 8=2
answer-2
7.
5(1) + 3(7)-1(to the third power)
exponents first-1
multiplication
5x1=5 + 3x7=21
21+5=26
26-1
answer-25
8. 8(2nd power)divided by 2(4) +3(7)-1
8 to the 2nd power =16
2(4)=8
3(7)=21
16 divided by 8+21-1
8+21=29
29-1=28
answer 28
Answer:
Step-by-step explanation:
The position equation is given as
and we are looking for the times when the position of the ball is 9 feet. That means that we simply plug in a 9 for s(t) and factor to solve for t:
and
and this is what we factor to find t:
t = .42 sec and then again on its way back down at t = .89 sec
Answer:
b = 5√6
c = 10√5
Step-by-step explanation:
This is a 30-60-90 triangle
the hypotenuse is always twice the short leg
c = 2(5√2)
c = 10√5
The long leg is alway √3 times the short leg
b = √3(5√2)
b = 5√6
