Answer: 2r=d

d=24.28590063

Step-by-step explanation:

vsphere=4/3pir^3

7500=4/3pir^3

times both sides by 3

22500=4pir^3

divide both sides by 4

5625=pir^3

divide bot sides by pi

1790.4931=r^3

cube root both sides

12.142950=r

2r=d

d=24.28590063 ft

Let f(x) = -4x - 2 and g(x) = 5x - 6. Find f*g and state its domain.
elixir [45]

Answer:  The answer is (c) -20x^2+14x-12;\textup{ all real numbers.}

Step-by-step explanation:  Given that there are two functions f and g, defined by

f(x)=-4x-2,\\\\g(x)=5x-6.

We are to find f*g and also its domain.

(f*g)(x)\\\\=f(x)g(x)\\\\=(-4x-2)(5x-6)\\\\=-20x^2+24x-10x-12\\\\--20x^2+14x-12.

Also, its domain will be all real numbers, since the function f*g is defined at all 'x' in real numbers.

Thus, the correct option is

-20x^2+14x-12.

Evaluate for m 32, n = 2, p = 8 and r = 4 (np + r) m​
TiliK225 [7]

Answer:

If m= 32 then the answer is 320

If you're looking to find m then the answer is m= -10

Step-by-step explanation:

(2 + 8)32

(10)32

320

(2+8)m

set it equal to 0

(2+8)m=0

(10)m=0

-10

m= -10

Solve for x, with variables on both sides of equation. (Note: x is the same thing as 1x) You must show your work!
bagirrra123 [75]
Hello! We already have the equation set up, which is 9x = x + 4. Let's solve for x. Subtract x from both sides to get each side by itself x - x cancels out. 9x - x is 8x. That leaves 8x = 4. Now, divide each side by 8 to isolate the x. 8x/8 cancels out. 4/8 is 4/8 or 1/2 in cimplest form. Let's plug this value in and see if it works. 9 * 1/2 is 4 1/2. 1/2 + 4 is 4 1/2. 4 1/2 = 4 1/2. There. x = 1/2.
