Answer

Answer: Volume = 9025.8 cm³

Step-by-step explanation:

--------------------------------------------------------

Find Radius :

--------------------------------------------------------

Base area = πr²

169π = πr²

r² = 169

r = √169

r = 13 cm

--------------------------------------------------------

Find height :

--------------------------------------------------------

Height = 13 + 4

Height = 17 cm

--------------------------------------------------------

Find Volume :

--------------------------------------------------------

Volume = πr²h

Volume = π(13)²(17)

Volume = 9025.8 cm³

--------------------------------------------------------

Answer: Volume = 9025.8 cm³

--------------------------------------------------------

The time of a pendulum varies as the square root of its length. If the length if a pendulum which beats 15seconds is 9cm, find t
8090 [49]

Answer:

length= 3.7 ft.

Step-by-step explanation:

T= (square root of length) * k

1.8 seconds = (square root of 3) * k

k= 1.8 seconds / (square root of 3)

a.) T= (square root of 11) k

substituting k:

T=(square root of 11) * 1.8 seconds / (square of 3)

T= 3.4 seconds

b.) 2 seconds = (square root of length) k

substituting k:

2 seconds =(square root of length) 1.8 seconds / (square root of 3)

Divide the equation by 1.8 seconds / (square root of 3):

2 seconds / [1.8 seconds / (square root of 3)] = (square root of length)

10(square root of 3) / 9 = (square root of length)

square both sides:

100/7 ft= length

length= 3.7 ft.

Hope this helps.

5-6. Find the constant of proportionality (unit rate) for each set of values. Then use the constant of proportionality to write
kakasveta [241]

5. The constant of proportionality is 1.5

The equation is <em>p </em>= 1.5×s

6. The constant of proportionality is 1.99

The equation is p = 1.99 × a

7. The variables Number of Pens and Cost  are not proportional

Please find attached the required graph

8. The variables Number of minutes and Words Typed are not proportional

Please find attached the required graph

The procedure for finding the answers are as follows;

5. The given data are presented as follows;

\begin{array}{ccc}Shirts \ (s)&&Profit \ (p)\\5&&7.50\\10&&15.00\\15&&22.50\end{array}

Where two variables, <em>s</em> and <em>p</em> are proportional, we get;

p ∝ s

Therefore;

p = C × s

C = p/s

Where;

C = The constant of proportionality

Therefore, the constant of proportionality, <em>C</em>, of the given variables, (number of shirts, <em>s</em>, and profit, <em>p</em>, is found as follows;

C = 7.50/5 = 15.00/10 = 22.50/15 = 1.5

The constant of proportionality, C = 1.5

The equation that relates the two values is <em>p </em>= 1.5×s

6.  For the apples to price relationship, we have;

\begin{array}{ccc}Apples \ (a)&&Price\ (p)\\4&&7.96\\5&&9.95\\6&&11.94\end{array}

Therefore;

p ∝ a

p = C × a

C = p/a

Plugging in the values gives;

C = 7.96/4 = 9.95/5 = 11.94/6 = 1.99

The constant of proportionality, C = 1.99

Therefore, the equation relating the two values is p = 1.99 × a

7. The given data is presented in a tabular form as follows;

\begin{array}{ccc}Number \ of \ pens  &&Cost\ \\1&&52\\2&&54\\3&&56\\4&&58\end{array}

A set of data is proportional or has a proportional relationship if their <em>x</em>, and therefore, y-intercept is (0, 0)

From the graph of the data, created with MS Excel, the y-intercept is 50 which is not equal to zero, therefore, the relationship between the data is not a proportional relationship

8. The given data is presented in a tabular form as follows;

\begin{array}{ccc}Number \ of \ Minutes&&Words \ Typed\ \\1&&50\\2&&90\\3&&140\\4&&180\end{array}

From the graph of the data, we have that the y-intercept of the line of best fir is 5, therefore, the relationship is not a proportional relationship

With the given slope of<br><br> 4/7, find the value<br><br><br> (2,6) and (x, 2);slope: 4/7
alexandr1967 [171]

Step-by-step explanation:

the slope is the ratio "y coordinate difference / x coordinate difference".

so,

(2 - 6) / (x - 2) = 4/7

-4 / (x - 2) = 4/7

-1 / (x - 2) = 1/7

-1 / (x - 2) = 1 / -(x - 2) = 1/7

-(x - 2) = 7

-x + 2 = 7

-x = 5

x = -5

so, the point is (-5, 2)
