From the garden's area 150 sqf we can find out the length of one side. That is √150= 12.2- we have to <span>round to the nearest tenth
And the length of the fence is: 4.12.2= 8.48 or 8.5 feet
Have fun</span>
Answer:
s - 8
Step-by-step explanation:
TO find the function rule, substitute (s-2) in place of v. Then simplify.
h(v) = v - 6
h(s - 2) = (s - 2) - 6
h(s - 2) = s - 8
Answer:
2.0 mph
Step-by-step explanation:
Considering a straight-line displacement, the current has a velocity acting on the same axis at which the motorboat is traveling. Assume that the current's velocity is positive in the downstream leg of the trip, the velocity of the current can be determined by:
![U: (V_{boat} - V_{current})*t_U=12\\D: (V_{boat} + V_{current})*t_D=12\\t_U +t_D = 2.5 = \frac{12}{10 - V_{current}}+\frac{12}{10 + V_{current}}\\2.5*(10^2-V_{current}^2)=120 -12V_{current}+120+12V_{current}\\-2.5V_{current}^2 +250 = 240\\V_{current}=\sqrt{\frac{10}{2.5}}\\V_{current} = 2\ mph](https://tex.z-dn.net/?f=U%3A%20%28V_%7Bboat%7D%20-%20V_%7Bcurrent%7D%29%2At_U%3D12%5C%5CD%3A%20%20%28V_%7Bboat%7D%20%2B%20V_%7Bcurrent%7D%29%2At_D%3D12%5C%5Ct_U%20%2Bt_D%20%3D%202.5%20%3D%20%5Cfrac%7B12%7D%7B10%20-%20V_%7Bcurrent%7D%7D%2B%5Cfrac%7B12%7D%7B10%20%2B%20V_%7Bcurrent%7D%7D%5C%5C2.5%2A%2810%5E2-V_%7Bcurrent%7D%5E2%29%3D120%20-12V_%7Bcurrent%7D%2B120%2B12V_%7Bcurrent%7D%5C%5C-2.5V_%7Bcurrent%7D%5E2%20%2B250%20%3D%20240%5C%5CV_%7Bcurrent%7D%3D%5Csqrt%7B%5Cfrac%7B10%7D%7B2.5%7D%7D%5C%5CV_%7Bcurrent%7D%20%3D%202%5C%20mph)
The speed of the current is 2 miles per hour.
