Answer:
y = x^2 +6x+14
Step-by-step explanation:
x = t - 3, y = t^2 + 5
x=t-3
Add 3 to each side
x+3 = t-3+3
x+3 =t
Substitute into the second equation
y = t^2 +5
y = (x+3)^2 +5
Foil the first term
y = (x+3) (x+3) +5
y = (x^2 +3x+3x+9) +5
y = x^2 +6x+9) +5
y = x^2 +6x+14
Answer:
2/15
Step-by-step explanation:
you put a one under the 3 and then flip it as the song says
<em>dividing fractions easy as pie flip the second and multiply. </em>
then you get
2/5 divided by 3/1 but you flip the 3/1 and then multiply
hope this helped :))))

Answer:
27 degrees
Step-by-step explanation:
First, we can draw this out. Since the altitude is 8000, we can make that the height, and it goes 16000 feet through the air, that can be the length. I have drawn this out, as shown in the image. Note that when drawing, because the airplane is going up and forward, that path should represent the hypotenuse. The angle of elevation is the angle connecting the length and the path, as shown by the angle x in the picture.
We know than tan(x) = opposite/adjacent, so tan(x) here = 8000/16000 = 1/2. Then, arctan(1/2) =x = 27 degrees
Hello,
