Answer:

The equation does have a solution

Step-by-step explanation:

You would first want to move the variable to one side of the equation by itself.

2.5x - 4 - 3 = -11

2.5x - 7 = -11

2.5x = -4

Then you want to put the variable by itself.

2.5x / 2.5 = -4 / 2.5

X = -1.6

This is the only solution to the equation

Answer:

x = 2.16

Step-by-step explanation:

Question :

$\frac{3.5x}{9} =\frac{4.2}{5}$

Use cross multiplication.

3.5x × 5 = 9 × 4.2

17.5x = 37.8

Divide both sides by 17.5.

x = 2.16

Karl starts the engine on his small private airplane. The engine drives a propeller with a radius of 9 feet and its centerline 1

Volgvan

Answer: The height of one propeller tip is 3.68 feet when t= 3.5 minutes.

Step-by-step explanation:

Given: The height of one propeller tip as a function of time is given by $h = 12.5 + 9 sin(750t)$ ), where h is the height in feet and t is the time in minutes.

Put t = 3.5 , we get

$h=12.5 +9 \sin (750\times3.5)\\\\=12.5+9\sin (2625)\\\\=12.5+9(-0.9802)\\\\=12.5-8.8218=3.6782\approx3.68$

Hence, The height of one propeller tip is 3.68 feet when t= 3.5 minutes.
