Hey, so basically just plug in the x values for x in the equation. First table the first x value is -1 so just plug it in to 3x so: 3(-1)= -3. That’s your y.

The volume inside of a sphere is V=4πr33 where r is the radius of the sphere. Your group has been asked to rearrange the formula

Semmy [17]

Answer:

Therefore,

$r=\sqrt[3]{\frac{3V}{4\pi }}$

is the required r

Step-by-step explanation:

Given:

Volume of inside of the sphere is given as

$V=\frac{4}{3} \pi r^{3}$

where r is the radius of the sphere

To Find:

r =?

Solution:

We have

$V=\frac{4}{3} \pi r^{3}$ ......Given

$3\times V=4\pi r^{3} \\\\\therefore r^{3}=\frac{3V}{4\pi } \\\\\therefore r=\sqrt[3]{\frac{3V}{4\pi }} \textrm{which is the expression for r}$

Therefore,

$r=\sqrt[3]{\frac{3V}{4\pi }}$

is the required r

Someone help, please and thank you

taurus [48]

Answer:

6√2

Step-by-step explanation:

Given,

θ = 45

Opposite side = 6

To find : - Hypotenuse

Formula : -

sin θ = Opposite side / Hypotenuse

[ The value of sin 45 = 1 / √2 ]

sin 45 = 6 / Hypotenuse

1 / √2 = 6 / Hypotenuse

Cross multiply,

Hypotenuse = 6√2

Describe the transformation from y= x + 4 to y= .5x + 4 Group of answer choices compresses stretches shifts right 4 shifts left

Nina [5.8K]

Answer:

This type of transformation is a horizontal stretch.

Step-by-step explanation:

Given

$y = x + 4$

$y = .5x + 4$

Required

Determine the type of transformation

The first function can be expressed as:

$f(x) = x + 4$

While the second function is:

$g(x) = f(0.5x)$

Solving f(0.5x), we have to substitute 0.5x for x in $f(x) = x + 4$

$f(0.5x) = 0.5x + 4$

So:

The second function is:

$g(x) = 0.5x + 4$

This type of transformation is a horizontal stretch.

i.e. f(x) stretched to g(x)
