A football is thrown by a quarterback to a receiver. The points in the figure show the height of the​ football, in​ feet, above
nevsk [136]

Answer:

Coordinates of the point B will be (14, 3.5).

Step-by-step explanation:

From the graph attached,

Distance between the Quarterback and Receiver = x-coordinate of the point B = 14 yards

Similarly, height of the football from the ground at point B = y-coordinate of the point B = 9 + \frac{12-9}{2}

                   = 9 + 1.5

                   = 10.5 feet

Since, 1 feet = \frac{1}{3} yards

10.5 feet = \frac{10.5}{3}

               = 3.5 yards

Therefore, coordinates of the point B will be (14, 3.5).

Question B,C and D I need answers to these parts.
Alik [6]
Explanation<h2>Part b</h2>

So in part (b) we must give the annual growth factor. For any quantity that increases annualy, this factor is the number by which the quantity multiplies itself every year. For a given quantity that increases at a rate of p% its growth factor is given by:

1+\frac{p}{100}

In this case the production of ethanol increases at a rate of 5.5% per year which means that the growth factor is:

1+\frac{5.5}{100}=1.055

Then the growth factor and answer to part (b) is 1.055.

In part (c) we must write an equation that models the increase in the ethanol production. Given an initial qunatity Q and an annual growth factor k the quantity after x years is given by multiplying the initial quantity by the growth factor raised to the x. Then we get:

C(x)=Q\cdot k^x

In this case we need a function for the amount of ethanol produced E, x years after 1990. The 0.9 billion gallons produced that year compose our initial quantity and knowing that the annual growth factor is 1.055 we have the desire equation:

E(x)=0.9\cdot1.055^x

And that's the answer to part (c).

In part (d) we have to compare the actual production of ethanol in 2008 to the one predicted by the equation of part (c). Remember that x represents the years passed after 1990 so for the year 2008 the value of x is given by:

x=2008-1990=18

So the number we are looking for is E(18):

E(18)=0.9\cdot1.055^{18}=2.359

So the production estimated for 2008 is 2.359 billions of gallons. Then the actual production of 9 billion gallons is higher than the one predicted by our equation.

HELP GEOMETRY!!!!!! The newest feature at the Great Park is the big orange balloon. The volume of this perfectly spherical ballo
WITCHER [35]

Answer: 8.3 ft

Step-by-step explanation:

Here, The volume of this perfectly spherical balloon is approximately 2361.7 cubic feet.

Since, the volume of a sphere, V= \frac{4}{3} \pi r^3

Where r is the radius of the sphere.

Here V= 2361.7 cubic feet

Therefore, 2361.7=\frac{4}{3} \pi r^3

⇒ r^3= \frac{21\times 2361.7}{88}

⇒r= 563.5875^{1/3}=8.2601344693≈8.3 feet

Thus, the radius of the sphere = 8.3 feet
