Answer:
x^2 + 4x + 7
Step-by-step explanation:
(2x + 6) + (x^2 + 2x + 1) Remove parentheses.
2x + 6 + x^2 + 2x + 1 Combine like terms and reorder.
x^2 + 4x + 7
Hope this helped!
I think it is −2.666666666666667 but i’m not sure!
SOH CAH TOA tells you the sine function of an angle gives the ratio of opposite side to the hypotenuse of the right triangle.
Sin = Opposite/Hypotenuse
In this problem, the angle is 15°, the hypotenuse is 3000 m and we want to find the length of the opposite side (the height above the ground).
sin(30°) = height/(3000 m)
Multiplying by 3000 m, we get
height = (3000 m)*sin(30°) = 1500 m
The height of the plane at that instant is ...
1500 m
