Answer:
Step-by-step explanation:
4 is coefficient
x is variable
12 is constant
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
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.
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.

What is another way to write 3 x (4+5) = 27?
Pleas help
Answer:
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.

First tip with numbers... All whole numbers are rational and all numbers, rational or irrational are real numbers. Rational numbers consist of whole numbers, integers, fractions, and so on... While irrational numbers are numbers that can't be simplified to a basic whole number or fraction like 36.
Pi (π) is an example of an irrational number.
36 is an example of a rational number.

help plz i’ll give extra points : )
Answer:
y = 6/5x - 24/5
Step-by-step explanation:
The two points we are given are (4, 0) and (9, 6). First, find the slope.
m = 6 - 0/9 - 4 = 6/5
Next, insert the values into the point-slope form formula. I'll use (4, 0) as the coordinates.
y - 0 = 6/5(x - 4)
y = 6/5x - 24/5

Answer and Step-by-step explanation:
You got the triangle at front, half of 6 is 3, so then you do 4 times 3 divided by 2, which is 6.
There are 4 of those triangles, so 4 times 6 is 24.
Now, we got two rectangles on top. 5 times 12 is 60, and 60 + 60 is 120.
the bottom rectangle is 6 times 12, which is 72.
Now we add.
24 + 120 + 72 is 216
216 [tex]in^2[/tex] is the answer.
