a water storage tank has a cylindrical shape. the base has a radius of 7 ft and a height of 15 ft. how much water can the tank hold at its maximum?

Answers

Answer 1

given:

radius= 7ft

height= 15ft

to find:

the amount of water the tank can hold as its maximum.

solution:

[tex]volume \: of \: cylinder = {\pi \: r}^{2} h[/tex]

[tex] = \pi \times {7}^{2} \times 15[/tex]

= 2309.07

therefore, the tank can hold 2309.07L of water as its maximum.

Answer is D

Remember to see the points of intersection of the graphs test for discriminant [b^2 - 4ac]

e.g. you have y = x^2 - 6x + 9, compare this to the general quadratic equation y=ax^2 + bx + c

Discriminant = (-6)^2 - 4(1)(9) = 0

For the graph to only touch x axis at one point discriminant must be equal to 0 so D is the answer as it is the only equations whose discriminant is equal to 0

Answers

The average rate of change of the trend line is 0.39

How to determine the average rate of change of the trend line?

The points are given as:

hr =>200, 158, 149, 146, 138, 137, 131, 116, 103.

w => 93, 94, 66, 81, 86, 75, 61, 69, 55.

Using a graphing calculator, we have the following calculation summary:

Sum of X = 1278Sum of Y = 680Mean X = 142Mean Y = 75.5556Sum of squares (SSX) = 6044Sum of products (SP) = 2355

The average rate (m) is then calculated using:

m = SP/SSX

This gives

m = 2355/6044

Evaluate the quotient

m = 0.38964

Approximate

m = 0.39

Hence, the average rate of change of the trend line is 0.39
