Answer:

408 cm^3

Step-by-step explanation:

You have to find the volume of each object individually. You first find the volume of the sphere, so you input the radius, which is 3, into the equation which comes out to be 108 cm^3. You then have to find the volume of the cylinder, and since you have the diameter of the cylinder, and you need the radius, and the radius is half of the diameter, you would input 5 into the equation as the radius, since half of 10 is 5. That comes out to be 300 cm^3, so then you add the two volumes together, which is 408 cm^3

Solve for C. 5/4= -4c + 1/4

dybincka [34]

5/4= -4c + 1/4

Inverse operation

$\frac{5}{4} = -4c + \frac{1}{4}$

- 1/4 -1/4

5/4 - 1/4 = 4/4

$\frac{4}{4} = -4c$
-4c/-4 = 4/4 ÷ -4/1

4/4 *- 1/4 = c
-4/8 = c
c = -1/2

Answer: $c = - \frac{1}{2}$

What is the inverse of x-2

SCORPION-xisa [38]

Answer:

y = x + 2

Step-by-step explanation:

The expression x-2 is from the equation y = x - 2.

To find the inverse of the equation, switch the "x" and "y" variables, then solve or isolate for "y", meaning to separate it from the other numbers.

y = x - 2 Original equation

x = y - 2 Switched "x" and "y" variables

x + 2 = y - 2 + 2 Add 2 to both sides to cancel out '-2' on the side with "y"

x + 2 = y

y = x + 2 Variable is on left side in standard formatting

To isolate, do the reverse operation for the number you want to get rid of.

On the side with "y", I wanted to get rid of '-2' so I could separate "y" from everything else. '+2' is the reverse operation for '-2'.

On a normally distributed anxiety test with mean 48 and standard deviation 4, approximately what anxiety test score would put so

lbvjy [14]

Answer:

54.56

Step-by-step explanation:

Given:

Mean, u = 48

Standard deviation, $\sigma$ = 4

Test score = 5%

Required:

Find the raw score, X.

Having a test score of 5% means the Zscore has to correspond to 95%, ie, 1 - 0.05 = 0.95.

Thus, $Z_0_._9_5 = 1.64$

To get X, use the formula:

$mu + z * \sigma$

= 48 + (4 * 1.64)

= 48 + 6.56

= 54.56

The anxiety test score that would put someone in the top 5% is 54.56

What do the rates of change in the example represent?

JulsSmile [24]

I don't know what the question is, but I may be able to help a little. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
