Find the midline for f(x)=−2+4cosx.

diamong [38]

The mid-line for f(x) = 4cos x is y = 0. In the given equation, the term -2 is described as the y-shift. Therefore the mid-line for f(x) = -2 + 4cos x is:
y = -2.

Find the radius of a sphere with a volume of 2304 pi cubic centimeters.

Shalnov [3]

Answer:

The radius of a sphere would be 12 cm.

Step-by-step explanation:

The formula for the volume of the sphere =

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

By putting the value of volume we can find the radius of the sphere.

Volume of the sphere = 2304 π cm³

$2304\pi =\frac{4}{3}\pi r^3$

$2304=\frac{4}{3} r^3$

$2304\times \frac{3}{4}=\frac{3}{4}\times \frac{4}{3}r^3$

$2304\times \frac{3}{4}=r^3$

576 × 3 = r³

$r=\sqrt[3]{1728}$

r = 12

The radius of a sphere would be 12 cm.

Question 2 of 10

azamat

Answer:

Step-by-step explanation:

THe equation given is

2x+2y=16

y=x-4

We put 2nd equation in first equation and first solve for x:

$2x+2y=16\\2x+2(x-4)=16\\2x+2x-8=16\\4x=16+8\\4x=24\\x=\frac{24}{4}\\x=6$

Now, since we know y = x - 4, we substitute x = 6 and get y:

y = x - 4

y = 6 - 4

y =2

The correct ordered pair is (6,2), answer choice C
