Answer:

Your answer is C. y= \sqrt[7]{\frac{x}{8} }

Step-by-step explanation:

f(x)=8x^7\\y = 8x^7

switch y and x to for inverse.

x = 8y^2

Now solve y by itself.

x=8y^7\\\frac{x}{8}=y^7\\ \sqrt[7]{\frac{x}{8} } =y

Answer:

f^-1(x)= \sqrt[7]{x} /8

Step-by-step explanation:

f(x)=8x^7

x^7=f(x)/8

x=\sqrt[7]{x} /8

f^-1(x)= \sqrt[7]{x} /8

A drawer contains 11 identical red socks and 8 identical black socks. Suppose that you choose 2 socks at random in the dark, wha
DedPeter [7]

Answer:

The probability of getting a pair of red socks is 0.322

Step-by-step explanation:

According to the given data we have that A drawer contains 11 identical red socks and 8 identical black socks, hence, the total number of socks is 19, therefore, in order to calculate the probability of getting a pair of red socks we would have to use the following formula:

probability of getting a pair of red socks=11C2/19C2

probability of getting a pair of red socks=55/171

probability of getting a pair of red socks=0.322

The probability of getting a pair of red socks is 0.322

A spherical ball with a volume of 972π in.3 is packaged in a box that is in the shape of a cube. The edge length of the box is e
aivan3 [116]
To find the volume of the box you will use the volume of the sphere formula to find the radius of the circular region of the sphere. You wil then double the radius to find the diameter.

V = 4/3 x pi x r^3
972 x pi= 4/3 x pi x r^3
729 = r^3
The cubic root of 729 is 9 because 9 x 9 x 9 = 729.

The radius is 9 inches, and the diameter is 18 inches.

The volume of the box is 18 in x 18 in x 18 in or 5832 in.³.

X+2y=8 x-2y=-4 solve by system of equations
Vsevolod [243]

Answer:

Step-by-step explanation:

x + 2y = 8 -----------(I)

x - 2y  = -4 -----------(II)

Add equation (I) & (II) and thus y will be eliminated and we can get the value of 'x'

(I)           x + 2y = 8

(II)          <u>x - 2y  = -4</u><u>      </u>{Now add}

           2x         = 4

                   x   = 4/2

x = 2

Substitute x =  2 in equation (I)

2 + 2y = 8

    2y = 8 - 2

    2y = 6

      y = 6/2

y = 3
