What is 5x to the 3rd power

Answer:

125x^3

Step-by-step explanation:

So you can write it like (5x)^3

Then, when there are parenthesis,you multiply the exponent for each number inside by the exponent on the outside. So, that would make it: 5^3x^3. Since 5^3 is 125, you can write it like, 125x^3.

Hope this was helpful!

Answer:

125x

Step-by-step explanation:

5^3=125 so, for 5x if there is no value of x, x just acts as a variable and the answer is 5x^3=125x

84+8x=15x+140
Subtract 84 from both sides
8x=15x+56
Subtract 15x from both sides
-7x=56
Divide both sides by -7

What is true about the number 3.872? Check all that apply.
Korvikt [17]

Answer:

The 7 is in the hundredths place.

The 3 is in the ones place.

3.872 is equivalent to (3 × 1) + (8 × 0.1) + (7 × 0.01) + (2 × 0.001).

Step-by-step explanation:

Given the number 3.872, to check all the given options that are true apply to the number, let's take a look at each position occupied by each digit. In order words, let's consider their place value.

Thus,

The 3 is in the ones place and as such has a value of 3.

8 is in the tenths place having a place value of 0.8 (⁸/10)

7 is in the hundredths place having a place value of 0.07 (⁷/100)

2 is in the thousandths place having a place value of 0.002 (²/1000)

Going by these, the following statements are true :

"The 7 is in the hundredths place."

"The 3 is in the ones place."

"3.872 is equivalent to (3 × 1) + (8 × 0.1) + (7 × 0.01) + (2 × 0.001)."

The number is pronounced as three and eight hundred seventy-two thousandths rather than the option given.

Therefore, only 3 if the options are correct

Suppose the polynomial function below represents the power generated by a wind turbine, where x represents the wind speed in met
Elis [28]

Answer:

<em>f(10) or the power generated by the wind turbine at the wind speed of 10 m/s is </em><em>190.26 kW</em>

Step-by-step explanation:

The given polynomial function is,

f(x) = 0.08x^3 + x^2 + x + 0.26

where,

x represents the wind speed in meters per second,

y represents the kilowatts generated.

Putting x=10, we can get the value of f(10).

So,

=f(10)

= 0.08(10)^3 + (10)^2 + (10) + 0.26

= 0.08(1000) + (100) + (10) + 0.26

= 80 + 100 + 10 + 0.26

=190.26

Therefore,at x=10 or when the wind speed is 10 m/s, then y or the power generated by the wind turbine will be 190.26 kW
