The total weight of the water in a full tank, to the nearest pound is 1056 pounds, if water filled with water in the 4 diameter hemispherical tank and weighs 62.4 pounds per cubic foot.

Step-by-step explanation:

         The given is,

              A hemispherical tank is filled with water and has a diameter of 4 feet.

              Water weighs 62.4 pounds per cubic foot

Step:1

             Formula to weight of water is,

                          = Volume of water tank × weight of water per foot......(1)

Step:2

             Formula to find volume of the tank is,

                        V = \frac{2}{3} \pi  r^{3}...................................(2)

             From given, r = Radius of Hemisphere

                        r = \frac{d}{2}

                           = \frac{4}{2}

                         r = 2 foot    

            From equation (2),        

                            = \frac{2}{3} × \pi × 2^{3}

                            = 16.755 cubic foot

Step:3

            From equation (1),

                            = 16.775 × 62.4              (∵ Water weighs 62.4 pounds per cubic foot )

                            = 1045.52 pounds        ( ∵ foot^{3} × \frac{pounds}{foot^{3}} = pounds )

                            ≅ 1046 pounds

            Weight of water in tank = 1046 pounds

Result:

           The total weight of the water in a full tank, to the nearest pound is 1056 pounds, if a hemispherical tank is filled with water and it has 4 feet diameter and water weighs 62.4 pounds per cubic foot.

We have been given a graph of function g(x) which is a transformation of the function f(x)=3^x

Now we have to find the equation of g(x)

Usually transformation involves shifting or stretching so we can use the graph to identify the transformation.


First you should check the graph of f(x)=3^x

You will notice that it is always above x-axis (equation is x=0). Because x-axis acts as horizontal asymptote.

Now the given graph has asymptote at x=-2

which is just 2 unit down from the original asymptote x=0

so that means we need shift f(x), 2 unit down hence we get:

y=3^x


but that will disturb the y-intercept (0,1)

if we multiply 3^x by 3 again then the y-intercept will remain (0,1)

Hence final equation for g(x) will be:

g(x)=3(3^x)-2

What is the third quartile of this data set? <br> 20, 21, 24, 25, 28, 29, 35, 37, 42
nata0808 [166]

Answer:

36

Step-by-step explanation:

⇒The question is on third quartile

⇒To find the third quartile we calculate the median of the upper half of the data

Arrange the data in an increasing order

20, 21, 24, 25, 28, 29, 35, 37, 42

Locate the median, the center value

<u>20, 21, 24, 25</u>, 28, <u>29, 35, 37, 42</u>

<u />

The values 20, 21, 24, 25 ------------lower half used in finding first quartile Q1

The value 28 is the median

The vlaues 29, 35, 37, 42...............upper half used in finding 3rd quartile Q3

Finding third quartile Q3= median of the upper half

upper half= 29,35,37,42

median =( 35+37)/2 = 36

1. What two quantities do you need to know to measure speed?
Vaselesa [24]

Answer:

Step-by-step explanation:

2/c

3/both magnitude and direction are needed to define it.

4/Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.

5/There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.

6/The rate at which velocity changes with time is called Acceleration is a measure of how quickly the velocity is changing.

7/The instantaneous speed of an object is then the magnitude of its instantaneous velocity. Speed tells you how fast. Velocity tells you how fast and in what direction.

A rectangle has length triple of its breadth It has the area of is 120cm² find its length, Breadth and permiter .​
baherus [9]

Answer:

The breadth is about 6.32cm and the perimeter is about 50.56cm.

Step-by-step explanation:

The formula for the area of a rectangle is l * w = A, where l is the length, w is the width or breadth, and a is the area. If the length is 3 times the width, it can be written as 3w. This can be substituted into the formula along with the area to get 3w * w = 120, or 3w^2 = 120. Then it could be solved as an equation.

(3w^2)/3 = 120 / 3

w^2 = 40

w ~ 6.32

Then 6.32 can be multiplied by 3 to find the length, whch is 18.96. The formula for the perimeter of a rectangle is 2(l + w) = P.

2(6.32 + 18.96) = P

2(25.28) = P

50.56 = P
