Answer:
6.46
Step-by-step explanation:
h(t) = (1/2)
+ v0t + h0
Origin is at surface of water (h = 0), up is positive.
a = -g = -9.8 m/
v0 = 25 m/s
h0 = 50 m
h(t) = -4.9t2 + 25t + 50
Find t when
7 = 
+ 25t + 50
- 25t - 43 = 0
t = [1/(2*4.9)] [25 ±√(
+ 4*4.9*43)]
t = (0.102)(25 ± 38.312)
t > 0 ⇒ use only the positive square root
t = (0.102)(25 + 38.312) ≅ 6.46 s
It is 7m above the water at about 6.46 s
Answer: 23 is 69160. You subtract high school from associates and multiplty youe answer by 10.
Step-by-step explanation:
$24.95−$6.95=$18. Thus 8 tubes of paint cost $18.
$188=$2.25 for 1 tube of paint.
Explanation:
Once you remove the cost of the canvas from the total price, you're left with only the cost of the 8 tubes of paint.
This is represented by
$24.95−$6.95=$18
If 8 tubes of paint cost $18, then all we have to do is divide 18 by 8 to get the cost of each individual tube of paint.
Thus
$188=$2.25
is the cost for one tube of paint.
Hope this is helpful to you..

Answer:
125 degrees.
Step-by-step explanation:
m < CBD = m < A + m < C ( by the External Angle of a Triangle theorem).
= 58 + 67 = 125 degrees.
