1st you need equation for the surface area of a sphere which is:
A=4*π*r^2
Where r=radius
r = diameter/2 or d/2

So
area of a sphere = 4*π*(d/2)^2

Plug in the area given
1041 = 4*π*(d/2)^2

Solve for d
1041/(4* π)=82.84

82.84 = (d/2)^2

Sqrt(82.84)=d/2

9.10=d/2

9.10*2= d

18.2=d
So the answer is 18.2 in

Find the quotient of -85^2-27n+76 / -17n-19

bagirrra123 [75]

Answer:
5n-4

Explanation:
The given expression is:
$\frac{-85n^2-27n+76}{-17n-19}$

1- Take the negative as a common factor from both the numerator and the denominator. This will give us:
$\frac{-(85n^2+27n-76)}{-(17n+19)}$

2- Cancel out the negative sign (common factor) from the numerator and denominator. This will give us:
$\frac{(85n^2+27n-76)}{(17n+19)}$

3- Factor the numerator. This wil give:
$\frac{(5n-4)(17n+19)}{(17n+19)}$

4- Finally, cancel out the (17n+19) which common in both numerator and denominator. This will give us the final expression:
5n-4

Hope this helps :)

Multiply or Divide (i need this for school tomorrow)

lions [1.4K]

Answer:

Ok so here are the simple rules of doing it (very easy) cause I’m not doing it all so . when multiplying a power with The same base keep the base but add the exponents. Dividing, keep the base (if their the same if not then its already simplified same with multiplication) but SUBTRACT the exponents. Also keep the parenthesis if it’s a negative number base.

I’ll do a few.

11) a^10. 11b) 5^4

12) (-2)^2.

13) 10^2. 13b) s^6

14) -4s^5(t^6) <- [Im not sure of this one)

15) x^3(y^3)

Please help me, I have no idea what the equation for the new path is. Thank you!!

Citrus2011 [14]

First, find the slope of the initial line;

m=(y₁-y₂)/(x₁-x₂)

m=(4-0)/(11-8)
m=4/3

If two lines are parallel, the slope is the same although the intercept can differ.

If this parallel lines passes through the point (4, 5);

y=(4/3)x+c <-- plug in coordinates to solve for c
5=(4/3)(4)+c
(15/3)=16/3+c
(15/3)-(16/3)=c
-1/3=c

Therefore, the final equation should be y=4/3x-1/3

Hope I Helped :)
