An observer 2.5 miles from the launch pad of a space shuttle measures the angle of elevation to the base of the shuttle to be 25

kotegsom [21]

Answer:

Height of shuttle at that instant = 1.17 miles

Step-by-step explanation:

Refer the given figure.

C is the position of rocket and B is the position of observer.

Here we need to find AC, that is the height of shuttle at that instant.

Using trigonometric rules on ΔABC, we have

$tan25=\frac{AC}{AB} \\\\tan25=\frac{AC}{2.5}\\\\AC=2.5\times tan25\\\\AC=1.17miles$

Height of shuttle at that instant = AC = 1.17 miles

Express as a trinomial (3x+8) (x+10)

docker41 [41]

Answer:

$3x^{2} +38x+80$

Step-by-step explanation:

Hello!

A trinomial is a expression consisting of three different terms

To turn this into a trinomial we multiply everything to each other

3x * x = $3x^{2}$

3x * 10 = 30x

8 * x = 8x

8 * 10 = 80

Now we put them all together in an equation

$3x^{2} +30x+8x+80$

Combine like terms

$3x^{2} +38x+80$

The answer is $3x^{2} +38x+80$

Hope this helps!
