Answer:
5 seconds it will hit the water.
Step-by-step explanation:
y=-16t²+400
add -16t² to both sides
-16t²=-400
divide both sides by 16
t²=-25
t=√25
t=5
Answer:
0.125
Step-by-step explanation:
0.5 =1/2
Now
5/8 - 1/2
5/8 - 1*4/2*4
5/8-4/8
(5-4)/8
1/8
0.125
Answer:
B
Step-by-step explanation:
The line is solid, so eliminate A and D.
Also, the line is shaded below, so this eliminates C.
one way is this:
if the 2 integers are x and y, then
x<√98<y
if we assume that x and y aer both positive then
square everybody
x²<98<y²
solve each
x²<98
square root both sides
x<9.89
since x must be an integer, x=9
98<y²
squaer root both side
9.89<y
since y must be an integer, y=10
√98 lies between 9 an 10
