One minute is 60 seconds. I'm using this equation: Vf= Vi+at
40/60=2/3=0.666...m/s^2
Answer:
y = 9x - 5
Step-by-step explanation:
Any line parallel to the given line y = 9x must also have the slope 9.
Substitute the known values (m = 9, h = 0, k = -5) into the point-slope equation of a straight line:
y - (-5) = 9(x - 0)
Then y + 5 = 9x, or
y = 9x - 5
Answer:
A = (5s^2t - 9st) (3t + 1)
Step-by-step explanation:
(5s^2 - 9s) (3t^2 + t)
= 15s2t^2 + 5s^2t - 27st^2 - 9st
= 5s2t (3t + 1) - 9st (3t + 1)
= ( 5s^2t - 9st) (3t+1)
Answer:
The dimensions are length=32 inches and width=24 inches
Step-by-step explanation:
Recall that perimeter of a rectangle is
![P = 2(w + l)](https://tex.z-dn.net/?f=P%20%20%3D%202%28w%20%2B%20l%29)
The ratio of its length to width is 4:3.
This implies that,
![\frac{l}{w} = \frac{4}{3} \\ l = \frac{4}{3} w](https://tex.z-dn.net/?f=%20%5Cfrac%7Bl%7D%7Bw%7D%20%20%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%20%5C%5C%20l%20%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20w)
We substitute P=112 inches, and l in terms of w to get;
![112 = 2(w + \frac{4}{3}w)](https://tex.z-dn.net/?f=112%20%3D%202%28w%20%2B%20%20%5Cfrac%7B4%7D%7B3%7Dw%29)
![56 = w + \frac{4}{3}w](https://tex.z-dn.net/?f=56%20%3D%20w%20%2B%20%20%20%5Cfrac%7B4%7D%7B3%7Dw)
![168 = 3w + 4w](https://tex.z-dn.net/?f=168%20%3D%203w%20%2B%204w)
![7w = 168](https://tex.z-dn.net/?f=7w%20%3D%20168)
![w = \frac{168}{7} = 24](https://tex.z-dn.net/?f=w%20%3D%20%20%5Cfrac%7B168%7D%7B7%7D%20%20%3D%2024)
The length is
![l = \frac{4}{3} \times 24 = 32](https://tex.z-dn.net/?f=l%20%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%20%5Ctimes%2024%20%3D%2032)
