round to the nearest
hundredth of milligram : 4.27
tenth of milligram: 4.3
milligram : 4
Answer:
The Answer would be B.
Step-by-step explanation:
Rearrange
5+2*(3+2*x)-(x+3*(x+1))=0
Step 2:
(5 + 2 • (2x + 3)) - (4x + 3) = 0
Step 3 :
8 = 0
Step 4 :
Equations which are never true :
8 = 0
This equation has no solution.
Answer:
see below
Step-by-step explanation:
h=−4.9t^2 +39.2t
When will if fall back to the ground
When will h=0
0 =−4.9t^2 +39.2t
Factor out a -t
0 = -t (4.9t -39.2)
Using the zero product property
-t =0 4.9t - 39.2 =0
t =0 4.9t = 39.2
t =39.2 /4.9
t =8
It will reach the ground again at 8 seconds
The maximum height is halfway between the zeros
(0+8)/2 = 4
It will reach the max height at 4 seconds, substituting this in to find the max height
h=−4.9 (4)^2 +39.2(4)
h = 78.4 meters
This will only be applicable between t=0 and t=8 seconds
0≤t≤8 seconds
Answer:
60
Step-by-step explanation:
f(t)+g(t)=(1^2+21)+(41-3)=1+21+38=22+38=60
0.70 the 9 is in the hundredth place so you use the 8 in the thousandths place to round it up to 0.70
