let f(x) = 1/x and g(x) = x² – 5x. What
two numbers are not in the domain of fºg?
Separate your answers with a comma.
Enter the correct answer.
Answer:
5,0
Step-by-step explanation:
f o g is a composite function, y values of g passed as x values into f.
f o g = 1/(x^2 - 5x)
in this case, the only way for the function to be undefined is when
x^2 -5x = 0
x(x - 5) = 0
x = 0 or x = 5
What is the equation of a circle with a center at (−3, 2) and radius 16?
Answer:
(x+3)^2 + (y+2)^2 = 16
Step-by-step explanation:
hi!
so the equation of a circle with the center (h,k) and a radius r is:
(x-h)^2+(y+k)^2 = r^2
- h is the x value
- k is the y value
- r is the radius
so using your information you can plug in the given values into the "blanket" formula
which would result in:
(x--3)^2 + (y+2)^2 = 16^2 --> since there is a double negative, you can change that to a positive :)
this means that your equation is:
[tex](x+3)^{2} + (y+2)^{2} = 16^2[/tex]
and you can even simplify 16^2 = 256
end formula!
[tex](x+3)^{2} +(y+2)^{2} = 256[/tex]

Ashley and Emma are reading the same article. Ashley is on page 1 of the article, but she can read 1 page per minute. Emma is already on page 5, but reads a page every 3 minutes.
What page is Ashley on after 5 minutes.
What equation can be used to represent the amount Emma has read?
How many minutes does it take before Ashley and Emma have read the same amount
Answer:
Part A)
Ashley will be on the sixth page.
Part B)
[tex]\displaystyle p=\frac{1}{3}m+5[/tex]
Part C)
Six minutes.
Step-by-step explanation:
Ashley is on the first page and she can read one page per minute.
Emma is on the fifth page and she can read one page every three minutes.
Part A)
We can write an equation for Ashley. Let m represent the amount of minutes that has passed.
Since she is already one the first page, our initial value is 1.
She reads one page every minute. So, after m minutes, she would have read m pages.
Therefore, our equation is:
[tex]p=m+1[/tex]
Where p is the total pages read after m minutes.
Then after five minutes, Ashley will be on the:
[tex]p=(5)+1=6[/tex]
Ashley will be on the sixth page after five minutes.
Part B)
Since Emma reads one page every three minutes, we can say that she reads 1/3 of a page every minute.
Since she started on page five, her equation is:
[tex]\displaystyle p=\frac{1}{3}m+5[/tex]
Part C)
So, both of their pages read must be equivalent. Therefore:
[tex]\displaystyle m+1=\frac{1}{3}m+5[/tex]
Solve for m. Subtract 1/3m from both sides:
[tex]\displaystyle \frac{2}{3}m+1=5[/tex]
Subtract 1 from both sides:
[tex]\displaystyle \frac{2}{3}m=4[/tex]
Finally, multiply both sides by 3/2:
[tex]\displaystyle m=4\Big(\frac{3}{2}\Big)=6[/tex]
So, it will take six minutes before Ashley and Emma have read the same number of pages.

Sasha is the manager at a factory.
Last weekend 15 employees assembled 390 identical wardrobes.
Sasha wants 1200 of these wardrobes to be assembled next weekend.
How many employees does Sasha need next weekend?
You must show your working.
The number of employees Sasha would need next weekend are = 46
Calculation of total employeesFor a weekend, 15 employees = 390 wardrobes
The number of wardrobes to be assembled next weekend= 1200
If 390 wardrobes = 15 employees
1200 wardrobes = X employees
Make x the subject of formula,
X = 1200 × 15/390
X = 18000/390
X = 46
Therefore, the number of employees Sasha would need next weekend are = 46

Scott drinks 6 cups of water a day. How many fluid ounces of water does Scott drink? (2 points)
Group of answer choices
36 fluid ounces
48 fluid ounces
52 fluid ounces
68 fluid ounces if your right I give u a lot of points
There are 48 fluid ounces of water Scott drink.
Define the term ounces?An ounce is a unit of measurement of weight or mass in both the US customary system and the British imperial system. In the US customary system, one fluid ounce of water weighs about 1.04 ounces (oz).
Each day, Scott consumes 48 fluid ounces of water.
To convert cups to fluid ounces, we need to multiply the number of cups by 8 (as there are 8 fluid ounces in one cup).
So, 6 cups of water is equal to:
6 cups × 8 fluid ounces per cup = 48 fluid ounces
Therefore, there are 48 fluid ounces of water Scott drink.
