Answer:
B. 15c > 1,800 + 10c
Step-by-step explanation:
Profit=Total revenue - total cost
Profit is achieved:
when total revenue is greater than total cost
TR>TC
Or
When total cost is less than total revenue
TC<TR
From the question
Total cost=1800+10c
Total revenue=15c
Profit=TR>TC or TC<TR
15c>1800+10c
Or
1800+10c<15c
Option B. 15c > 1,800 + 10c satisfies the condition that Profit=TR>TC
Answer:
Circumference is 18.84 feet. Area is 28.26 square feet.
Step-by-step explanation:
Given:
Radius of the circle, ![r=3\textrm{ ft}](https://tex.z-dn.net/?f=r%3D3%5Ctextrm%7B%20ft%7D)
The value of
is 3.14.
Now, circumference of a circle of radius
is given as:
![Circumference=2\pi r=2\times 3.14\times 3=18.84\textrm{ ft}](https://tex.z-dn.net/?f=Circumference%3D2%5Cpi%20r%3D2%5Ctimes%203.14%5Ctimes%203%3D18.84%5Ctextrm%7B%20ft%7D)
Also, area of the circle of radius
is given as:
![Area=\pi r^{2}=3.14\times (3)^{2}=3.14\times 3\times 3=28.26\textrm{ }ft^{2}](https://tex.z-dn.net/?f=Area%3D%5Cpi%20r%5E%7B2%7D%3D3.14%5Ctimes%20%283%29%5E%7B2%7D%3D3.14%5Ctimes%203%5Ctimes%203%3D28.26%5Ctextrm%7B%20%7Dft%5E%7B2%7D)
Therefore, the circumference of the circle is 18.84 feet and area of the circle is 28.26 square feet.
Answer:
Please use " ^ " for exponentiation: x^2 + 2x + 8 ≤ 0.
Let's solve this by completing the square:
x^2 + 2x + 8 ≤ 0 => x^2 + 2x + 1^2 - 1^2 + 8 ≤ 0. Continuing this rewrite:
(x + 1)^2 + 7 ≤ 0
Taking the sqrt of both sides: (x + 1)^2 = i*sqrt(7)
Then the solutions are x = -1 + i√7 and x = -1 - i√7
There's something really wrong here. I've graphed your function, x^2 + 2x + 8, and can see from the graph that there are no real roots, but only complex roots. Please double-check to ensure that you've copied down this problem correctly.

Answer:
$133
Step-by-step explanation:
Put 14 where t is in the formula and do the arithmetic.
c = -9.5×14
c = 133 . . . . cost in dollars
Sanjay paid $133 for the 14 t-shirts he bought.
