We know that that the water level is 3 feet below your deck. (-3)
When the tide goes out, the water level lowers 1 foot. (-1)
A storm surge comes in, the water level rises 2 feet. (+2)
New water level: -3-1+2= -4+2= -2
The new water level is 2 feet below the dock.
Mark as brainliest pls. Any concern or comment, talk to me.
Children=x
Adults=y
* x + y =275 => x = 275 - y
* 3.00x + 6.40y = 1284 <=> 3.00(275 - y) + 6.40y = 1284 <=> ... <=> y = 135 => x = 275 - 135 = 140
Children: 140
Adults: 135
1.679 kg * (40 min)/(kg) + 20 min = 67.16 min + 20 min = 87.16 min
Answer:
Step-by-step explanation:
f(x) = x^2 + 5
g(x^2 + 5) = (x^2 + 5)^2= x^4 + 5x^2 + 5x^2 + 25 = x^4 + 10x^2 + 25
h(x^4 + 10x^2 + 25)= -2(x^4 + 10x^2 + 25)
-2x^4 - 20x^2 - 50
