H(x) = 5 - x
Domain: Df = R
f(x) = 3x + 2
Domain: Df = R
Dh = Df therefore (h·f)(x) = h(x) · f(x)
(h·f)(x) = (5 - x)(3x + 2) = 5(3x + 2) - x(3x + 2) = 5·3x + 5·2 - x·3x - x·2
= 15x + 10 - 3x² - 2x = -3x² + 13x + 10
Answer:
3.14
That is the value of pi to the second decimal point
Answer:
77 feet below sea level.
Step-by-step explanation:
Since y is the time the submarine is ascending, we can plug it in for y and find our answer. We can create an equation where D is the depth and y is time ascending: D = -230 + 17y
Substitute 9 for y:
D = -230 + 17(9)
D = -230 + 153
D = -77
The depth of the submarine after 9 minutes will be 77 feet below sea level. Hope this helps, and Brainly will be highly appreciated.
