Step-by-step explanation:
1. 5/8 = 62.5%
2. 1/5 = 20%
3. 4 2/3 = 4.66%
Answer:
x=4
Step-by-step explanation:
-2(x+2)=-12
x+2=-12/-2
x+2=6
x=6-2
x=4
Answer:
1302
Step-by-step explanation:
10C5 + (5C1×10C4) = 1302
Take the 4 out to get 4(x^2-12.5)
5. To figure this out you must find when y = 0
-16t^2 = -200
t^2 = 12.5
Square root
t = 3.54 C
6.
Axis of symetry = -.5 (always a vertical line down vertex)
Vertex = (-.5, -6.5) (the minimum of the graph)
B
7. To find maximum height you must find the vertex
The maximum height is 549 feet after 5.75 seconds
C
9. Solve for X
x^2 = 1
Square root
X = plus or minus 1
A
