RideAnS [48]

Test each

if angle is increased, rock will go further
if the angle starts at 0, then increases to 90 degrees (straight up) the rock will go up then bounce off of the launcher going either front or back, but vastly shorter than if it were pointed straight ahead

2nd one
changing angle change the distance
we see that is true

85% of the people survey thought the price of the car wash was reasonable. If 164 people thought the cost of the car wash was re

8090 [49]

192 people were survey

Step-by-step explanation:

The given is:

85% of the people survey thought the price of the car wash was reasonable
164 people thought the cost of the car wash was reasonable

We need to find how many people were survey

Assume that x people were survey

∵ There were x people survey

∵ 85% of them thought the price of the car wash was reasonable

∴ The number of the people who thought the price of the car wash

was reasonable = 85% × x

∵ 85% = $\frac{85}{100}$ = 0.85

∴ The number of the people who thought the price of the car wash

was reasonable = 0.85 x

∵ 164 people thought the cost of the car wash was reasonable

- Equate 0.85 x and 164

∴ 0.85 x = 164

- Divide both sides by 0.85

∴ x = 192.94

∵ x represents a number of people, then it must be integer

∴ The number of people were survey = 192

192 people were survey

Please apply the properties of rational exponents to simplify expressions with radical or rational exponents. Explain the steps

schepotkina [342]

Step-by-step explanation:

Product property

If the bases are the same, you don't multiple them. However, if they are the same, you do multiple for example : (2³ * 2¹ = 2⁴.when the bases are the same) (2³ * 3¹ =6⁴. When the bases are not the same
We add the index.

Quotient property

Same here, if the bases are the same, they stay the way they were
We subtract the index

Power property

Here we multiple the index because of the bracket for example : (9²)²= 9⁴

Negetive exponent property

When ever the index has a negative sign its convected to a fraction, for instance : 9¯² = 1 /9²
Note, when it turns to a fraction th index becomes positive
