Determine the volume and the surface area of the three dimensional figure.
Over [174]

Answer:

A = 452.39 cm^2

V = 904.78 cm^3

Step-by-step explanation:

A= 4pi r^2

A = 4 (pi) (6^2) = 452.39 cm^2

Volume = (4/3)(pi)(r^3)

V = (4/3)(pi)(216) = 904.78 cm^3

Please help and explain how to do this math problem. :c
Novosadov [1.4K]
The answer would be mode= 16, Median= 16, mean=16.91, range=8. The mode is which number on the number line has the most dots on it, in this case it’s 16. For the mode you would go from side to side and cross each dot off till you reach the middle. And once again in that case it’s 16.

Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x + 6)? T
Alenkasestr [34]

Answer:

The graph of y = f(x) will shift left 6 units, as shown in figure a.

Step-by-step explanation:

A translation means we are able to move the graph of a function up or down - normally called Vertical Translation -  and right or left - commonly called Horizontal Translation.

If we replace the graph of y = f(x) with the graph of y = f(x + 6). It means we have added 6 units to the input, meaning the graph y = f(x) will shift left by 6 units as 6 is being added directly to the  x, so it is f(x + 6).

For example, if y = x² is the original function and of 6 is directly added to x i.e. f(x + 6), making it y = (x + 6)². So, we can easily observe that there will be a horizontal translation left of 8 units, as shown in figure a.

So, the graph of y = f(x) will shift left 6 units.

Keywords: graph shift, translation

What is the value of cos(15degrees)?
Temka [501]

Answer:

The answer is root 6 + root 2/4

Step-by-step explanation:

Cos (15)

Rewrite the expression

write (15 degrees) as a difference

cos ( 45 degrees - 30 degrees)

cos ( 45 degrees - 30 degrees)

Expand the expression

Use cos ( t - s ) = cos (t) cos (s) + sin (t) sin (s)

to expand the expression

cos (45 degrees) cos ( 30 degrees) + sin ( 45 degrees ) sin ( 30 degrees)

cos (45 degrees) cos ( 30 degrees) + sin ( 45 degrees ) sin ( 30 degrees)

calculate the expression

use the trigonometric values table or unit circle to calculate the expression

root 2/root 2 × cos (30 degrees) + sin (45 degrees) sin (30 degrees)

root 2/root 2 × root 3/root 2 + sin (45 degrees) sin (30 degrees)

root 2/ root 2 × root 3/root 2 + root 2/root 2 × sin (30 degrees)

root 2/root2 × root 3/root 2 + root 2/root 2 × 1/2

root 2/root2 × root 3/root 2 + root 2/root 2 × 1/2

Multiply

root 2/root 2 × root 3/root 2 only

Multiply by the fractions

root 6/ root 4 + root 2/ root 2 × 1/2

Multiply root 2/ root 2 × 1/2 only

6 root / root 4 + root 2/ root 4

write all numerators above the denominator

root 6 + root 2 / 4
