Answer:

[tex]5x^3-2x^2+2x+9[/tex]

Step-by-step explanation:

(5x^3+4x^2)−(6x^2−2x−9)

To find the opposite of 6x^2−2x−9 find the opposite of each term.

5x^3+4x^2−6x^2+2x+9

Combine 4x^2 and 6x^2 to get −2x^2.

Step-by-step explanation:

3 x (5+4) = 27

Hope that helps!

The another way to write 3 x (4+5) = 27, is 3 x (5+4) = 27.

What is  multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

3 x (4+5) = 27

i.e. 3 x (5+4) = 27

Hence, The another way to write 3 x (4+5) = 27, is 3 x (5+4) = 27.

Answer:

B.

Step-by-step explanation:

edge2020

For which of the following increasing functions f does (f-1)'(20) = 1/5
A f(x)= x + 5
B f(x) = x^3 + 5x + 20
C f(x) = x^5 + 5x + 14
D f(x)= e^x+ 5x + 19

Answers

Answer:

D f(x)= e^x+ 5x + 19

Step-by-step explanation:

D f(x)= e^x+ 5x + 19

We want to see for which one of the given functions, the inverse derivate evaluated in x = 20 is equal to 1/5.

The correct option is B:  f(x) = x^3 + 5x + 20

Remember that two functions f(x) and g(x) are inverses if:

f( g(x)) = g( f(x))) = x

And for the inverse derivate of a function, we have the rule:

[tex]\frac{d}{dx} [f^{-1}(f(x))] = \frac{1}{f'(x)}[/tex]

So first we need to find for what value of x each function is equal to 20, and then we need to see if the derivate of the function evaluated in that same value of x is equal to 5.

For example, for the first option we have:

A: f(x) = x + 5

We find the x-value such that the function is equal to 20.

f(15) = 15 + 5 = 20

We derivate the function.

f'(x) = 1

We evaluate the function in the x-value we got above.

f'(15) = 1

This is not the correct option, as this is not 5.

Now we need to do that for all the given options.

The only correct option will be the second one:

B: f(x) = x^3 + 5x + 20

First we find the x-value such that this is equal to 20

f(0) = 0^3 + 5*0 + 20 = 20

Then the x-value is x = 0.

Now we find the derivate of f(x).

f'(x) = 3*x^2 + 5

Now we evaluate that in the x-value we got before:

f'(0) = 3*0^2 + 5 = 5

As wanted, this is equal to 5.

Then we have:

[tex]\frac{d}{dx} [ f^{-1}( f(0))] = \frac{1}{f'(0)} \\\\\frac{d}{dx} [ f^{-1}(20)] = \frac{1}{5}[/tex]

As wanted.

Please help! This is due in a few minutes! Reese and Kevin have been working together to try and lose weight. Reese's weight loss can be modeled by the equation y = -4x + 203 where y is his total with weight and x is the number of weeks he has been working out. Kevin's weight loss progress is shown on the graph below. Who is losing weight at a faster rate? Explain your reasoning.

Answers

The equation for the graph would be y = -1/4x + 200. So Reese is loosing weight at a faster rate than Kevin. (I’m not sure tho so someone check this)

Answer:

The answer is Kevin, Kevin is loosing weight faster

Step-by-step explanation:

The reason its kevin is because Reese is loosing weight and his is -4 and Kevins number is -5 so it would be kevin for the answer.
