The answer 7x + 5y

Work: we distribute 6 to x and y and then add x and minus y

6•x
6•y

6x + x +6y - y

Combine like terms:
=7x + 5y

This is an isosceles triangle.

So, we have:

Tangent 32 = x/11

Tangent 32 (11) = x

Which expression represents the calculation “subtract 4 from 12, then divided by 8”? A) 4 ÷ (12 − 8) B) (12 − 4) ÷ 8 C) (4 − 12)

Svetlanka [38]

The answer is B

As the question states that you need to "subtract 4 from 12" that means that you are taking 4 away from 12, so it would be 12-4.

Then it says to divide by 8. This means that for the subtraction to happen first, it must be withing parenthesis, so that would make the expression become

(12-4)÷8

Naomi starts the engine on her small private airplane. The engine drives a propeller with a radius of 8 feet and its centerline

icang [17]

Answer:

5.13 feet

Step-by-step explanation:

Engine is driving the propeller with a radius of 8 feet and its centerline 13 feet above the ground.

And the speed is 700 revolutions per minute, the height of one propeller tip as a function of time is given by:

$h=13+8 \sin(700t)$

We have been asked to find the value of height, 'h', when t=4 minutes.

Plugging the value of time, 't', in the equation, we already know that we need to use degrees (not radians) we get:

$h=13+8 \sin (700 \times 4)$

$h=13+8 \sin (2800)$

$h=13+8 \times (-0.984)$

$h=13+(-7.872)$

$h=13-7.872$

$h=5.128\approx 5.13$

So the height of one propeller tip at t=4 minutes is 5.13 feet.
