I cant solve this help –8x + 15 < 71

Ratling [72]

Answer:

x > -7

Step-by-step explanation:

Isolate the variable, x. Treat the < sign like an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& roots)

Multiplication

Division

Addition

Subtraction

First, subtract 15 from both sides:

-8x + 15 (-15) < 71 (-15)

-8x < 71 - 15

-8x < 56

Next, divide -8 from both sides of the equation. Note that when you divide by a negative number, you must flip the sign:

(-8x)/-8 < (56)/-8

x < (56)/-8

x > -7

x > -7 is your answer.

A pile driver falls freely from a height of 4.50 m above a pile. What is its velocity as it hits the pile? Remember to include y

faltersainse [42]

Answer:

9.4 m/s

Step-by-step explanation:

We are given that

Height of pile driver above a pile =h=4.5 m

Acceleration due to gravity= $g=9.8m/s^2$

According to law of conservation of energy

K.E=Potential energy

$\frac{1}{2}mv^2=mgh$

$v^2=2gh$

$v=\sqrt{2gh}$

Substitute the values

$v=\sqrt{2\times 9.8\times 4.5}$ m/s

$v=9.4 m/s$

Hence, the velocity of pile driver as it hits the pile=9.4 m/s
