Answer: 0.29
Step-by-step explanation:
If you calculate it's:
0.28950661
You round to the nearest hundred bc it's too long.
Find the number in the hundredth place 8 and look one place to the right for the rounding digit 9. Round up if this number is greater than or equal to 5 and round down if it is less than 5.
Answer:
y = -x
Step-by-step explanation:
We know that parallel means the two lines have the same slope, so in this case the slope is -1.
Using our y = mx + b equation, we have
y = -x + b
Plug in our -2 and 2 into the equation
2 = - (-2) + b
2 = 2 + b
0 = b
Put in the b
y = -x + 0
y = -x

Answer:
the answer is B
Step-by-step explanation:
<em>ik because i got it right.</em>
A=g
v=⌠g dt
v=gt+C, where C=v initial
v=gt+vi
h=⌠v dt
h=gt^2/2+vit+C, where C=h initial
h=gt^2/2+vit+hi
We are told that vi=42 ft/s, hi=0, and we know g≈-32 ft/s^2 so
h(t)=-16t^2+42t
The ball will hit the ground when h=0 so
-16t^2+42t=0
-2t(8t-21)=0, since t>0
8t-21=0
8t=21
t=21/8
t=2.625 sec
t≈2.6 sec (to nearest tenth of a second)
