Suppose Paul kicks a soccer ball straight up into the air with an initial velocity of 96 feet per second. The function f(x) = -1

6t2 + 96t gives the height, in feet, of the soccer ball after t seconds. This function is shown in the graph below.
What do the x-intercepts represent in this real life situation in regards to the height of the soccer ball at that time?

We are told that the function f(t) outputs the height at t seconds.

The x-intercept is when y = 0. This is the same as saying when f(t) = 0.

When f(t) = 0, the height is 0, so the x-intercepts represent when the height is 0 and the soccer ball leaves the ground and lands back on the ground.

What is the volume of a right circular cylinder with a base diameter of 17.5 ft and a height of 24.5 ft?
Natasha_Volkova [10]

Answer:

The volume of a right circular cylinder with a base diameter of 17.5 ft and a height of 24.5 ft is:

5889.95 ft³

Step-by-step explanation:

We are given a base diameter of a right circular cylinder as :

d = 17.5 ft.

hence radius of cylinder i.e. r =d/2 = 8.75 ft.

height of the cylinder = 24.5 ft.

now we know that volume of cylinder i.e. V is given by :

V = πr²h

putting the value of r and h in the given formula to obtain the volume

V = 3.14×(8.75)²×24.5

   = 5889.95 ft³

hence, the volume of a right circular cylinder with a base diameter of 17.5 ft and a height of 24.5 ft is:

5889.95 ft³

What is the domain of the function represented by the graph?
Natalija [7]

The domain of given function is: -3≤x≤3

Step-by-step explanation:

The domain is the set of all possible inputs of the graph. In a graph, the input values are plotted on x-axis and the output or range is plotted on y-axis.

In the given figure we can see that the x-values that are involved in the graph of function are between -3 and 3. So the domain of the function will be:

-3≤x≤3

Hence,

The domain of given function is: -3≤x≤3

Keywords: Domain, Range

 There are 7 Democrats and 6 Republicans on a local city council. A planning committee of 6 for affordable housing needs to be
Brut [27]

Answer:

The probability is 0.383.

Step-by-step explanation:

There are 7 democrats and 6 republicans  

Number of ways in which 4 democrats and 2 republicans can be selected=\[{}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}\]

Number of ways in which 5 democrats and 1 republican can be selected= \[{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}\]

Number of ways in which 6 democrats can be selected = \[{}^{7}{{C}_{6}}\]

So, favourable outcomes are \[{}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}+{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}+{}^{7}{{C}_{6}}\]

Total possible outcomes =\[{}^{13}{{C}_{6}}\]

Now, probability=\[\frac{Favourable}{Possible}=\frac{{}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}+{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}+{}^{7}{{C}_{6}}}{{}^{13}{{C}_{6}}}=0.383\]

Liev is assembling a coffee table. The diagram below is from the instruction manual and shows the table after the first two legs
elixir [45]

Answer:

The support is 41 inches long.

Step-by-step explanation:

There's two ways we can do this: one with the diagonal formula and one without.

Since we know that Point C is halfway down leg A and that the table legs are 18 inches tall, Point C is 9 inches down leg A. The support, from Point C to Point D, will form a diagonal, the length of which we need to find. We know from the diagram that the width of the table is 24 inches and that its length is 32 inches. We have a height, length, and width for this problem, so let's imagine a rectangular prism, which has all three of those things, instead of a table. The formula for finding a rectangular prism's diagonal is d = \sqrt{l^{2} + w^{2} + h^{2} }. Let's put in those numbers:

d = \sqrt{32^{2} + 24^{2} + 9^{2} } =  41

Therefore, the support is 41 inches long.

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

Another way you can do this is to use the Pythagorean Theorem twice: once to find the diagonal of the tabletop and another time for the support.

24^{2} + 32^{2} = c^{2} \\576 + 1024 = c^2\\1600 = c^2\\\sqrt{1600} = \sqrt{c^2}\\ 40 = c

Now that we know the corner-to-corner distance for the tabletop, we'll use that and the 9 inch distance for Point C to find the distance between C and D:

9^{2} + 40^{2} = c^{2}\\ 81 + 1600 = c^2\\1681 = c^2\\\\sqrt{1681} = \sqrt{c^2} \\41 = c

Again, the support is 41 inches long.
