Answer:
y = 2sin(x/2 - pi/4) + 1
Step-by-step explanation:
The normal sine has a range of [-1, 1]. This one has a range of [-1, 3], so the amplitude is 2 times higher (4 vs 2).
After that, 2sin(x) has a range of [-2, 2], but this one has a range of [-1, 3], so we need to shift it upwards by 1.
We now know that the answer is 2sin(____)+1.
A normal sine has it's middle point while rising at x = 0, but this one has it at x = pi/2 - so we need to shift a sine to the right by pi/2.
Lastly, a sine has a cycle of length 2pi, but this one has a cycle of length 4pi. We can achieve that by dividing the argument 2.
We now know that the answer is 2sin(x/2 - pi/4) + 1. We can plot it to verify.

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

Step-by-step explanation:
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.

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.

Which of the following shows the correct order of numbers? • |-1|, -3/4 , 0 , 7/8 , 0.87 • -3/4, 0 , 7/8 , 0.87 , |-1| • -3/4 , 0 , 0.87 , 7/8 , |-1| • |-1|, -3/4 , 0 , 0.87 , 7/8
Answer:
The third bullet point.
-3/4 , 0 , 0.87 , 7/8 , |-1|Step-by-step explanation:
I hope this helps you on your journey to success!
The ascending order of numbers is -0.75<0<0.87<0.875<1 and the descending order of numbers is 1>0.875>0.87>0>-0.75.
The given set of numbers is -3/4, 0, 0.87, 7/8, |-1|.
We need to order the given set of numbers.
How to order the numbers?When ordering numbers, we first start by comparing two numbers at a time. You can do this by either arranging the numbers in ascending or descending order.
Now, |-1| can be written as 1, -3/4=-0.75 and 7/8=0.875.
Ascending order of numbers:
-0.75<0<0.87<0.875<1
Descending order of numbers:
1>0.875>0.87>0>-0.75
Therefore, the ascending order of numbers is -0.75<0<0.87<0.875<1 and the descending order of numbers is 1>0.875>0.87>0>-0.75.
