I could use some help doing this simple math problem lol.

alexira [117]

$D:k-9\geq 0 \wedge k\geq0\\
D:k\geq 9 \wedge k\geq0\\
D:k\geq 9\\
\sqrt{k-9}-\sqrt k=-1\\
\sqrt{k-9}=-1+\sqrt k\\
k-9=(-1+\sqrt k)^2\\
k-9=1-2\sqrt k+k\\
2\sqrt k=10\\
\sqrt k =5\\
k=25

Help with 14, 15, and 16 please ?

lara31 [8.8K]

14. 36x^2 - 16
4(9x^2 - 4) =
4(3x + 2)(3x - 2) <==

15. 3x^2 + 10x - 8
(3x - 2)(x + 4) <==

16. 5x^2 - 16x + 15 = 4x - 5
5x^2 - 16x - 4x + 15 + 5 = 0
5x^2 - 20x + 20 = 0
5(x^2 - 4x + 4)
5(x - 2)(x - 2)
x - 2 = 0....x = 2

What is the approximate volume of a cone with a height of 6 mm and radius of 18 mm?

Rudik [331]

Answer:

v = 2034.72 mm³

Step-by-step explanation:

radius = 18mm

height = 6mm

pi = 3.14

v = πr²h/3

v = 3.14 * (18mm)² x 6mm/3

v = 3.14 * 324mm² x 2mm

v = 2034.72 mm³

James has a dog grooming service. He charges a flat rate of $50 per month, plus $10 per grooming. Bradly does not charge a month

solmaris [256]

Answer:

The numbers of grooming visits for which James and Bradly would charge the same amount is 2

Step-by-step explanation:

Let

w -----> the numbers of grooming visits

y ----> the charge in dollars

we know that

<em>James</em>

$y=10w+50$ ----> equation A

<em>Bradly</em>

$y=35w$ ----> equation B

equate equation A and equation B

$35w=10w+50$

Solve for w

$35w-10w=50$

$25w=50$

$w=2$

therefore

The numbers of grooming visits for which James and Bradly would charge the same amount is 2
