It should more than likely be 3/4 or 75%.

Solve for x:
4 x^2 + 2 = 20

Subtract 2 from both sides:
4 x^2 = 18

Divide both sides by 4:
x^2 = 9/2

Take the square root of both sides:
Answer: |x = 3/sqrt(2)                  or                x = -3/sqrt(2)

Solve the following system:
{2 x - 8 y = 56 | (equation 1)
6 x + 8 y = -88 | (equation 2)
Swap equation 1 with equation 2:
{6 x + 8 y = -88 | (equation 1)
2 x - 8 y = 56 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{6 x + 8 y = -88 | (equation 1)
0 x - (32 y)/3 = 256/3 | (equation 2)
Divide equation 1 by 2:
{3 x + 4 y = -44 | (equation 1)
0 x - (32 y)/3 = 256/3 | (equation 2)
Multiply equation 2 by 3/32:
{3 x + 4 y = -44 | (equation 1)
0 x - y = 8 | (equation 2)
Multiply equation 2 by -1:
{3 x + 4 y = -44 | (equation 1)
0 x+y = -8 | (equation 2)
Subtract 4 × (equation 2) from equation 1:
{3 x+0 y = -12 | (equation 1)
0 x+y = -8 | (equation 2)
Divide equation 1 by 3:
{x+0 y = -4 | (equation 1)
0 x+y = -8 | (equation 2)
Collect results:
Answer: |x = -4                and           y=-8  OR B

32 + 1,378 is 1410

-4^4 is 256. The reason is because the power operation (4^4) takes precedence, and is calculated first. Then it brings down the minus sign. If you were to write like this:(-4)^4 =+256. Try it and see.

math is awesome

because when you do 4^2, it's equal to 4*4, and then when you do 16*4, and then 64*4, that totals to 4. basically the first step takes two fours and then the other 2 steps take only one

Yes

You don't need to change base to solve this problem.

log 4 to base 4  =  1   and log 4 to base 16  is  1/2.          4^1 =4    and 16^1/2 =4

So x = 3/2

The question is testing your understanding of logs,rather than just being able to use them without really knowing the theory.

The base 16 log of 4   means what' power do I need to raise 16 to in order to get 4.' and since sqrt 16 =4  ,it's 1/2.

Remember that a logarithm is an index,that always helps if you are getting confused between base and index.

Here is the answer

A sphere has a volume of 356 cm3. Calculate the surface area of the sphere. pls help

Find the radius, first.....so we have

356 = (4/3) * pi * r^3       divide both sides by  (4/3) pi

[ 356 ]  / [(4/3)pi]  = r^3     simplify 

[267 /pi]  = r^3       take the cube root of both sides

[257/pi]^(1/3)   = r

Surface area  =  4*pi * r^2  =

4 * pi * ( [257/pi]^(1/3) )^2  ≈  236.81 cm²

Approximately 1.73205080757 and sqrt(3) is in simplest radical form.

You just can

You were the first one to post all day

it depends where you live and if you dont have an apple phone you can always use a map or ask the nearest person if they know where it is

maybe Kentucky, Indiana, Maryland, Ohio...etc

don't know where you live
