You can think of it as y=-(x-16)^2 to give you an upside down parabola with the center point at x=16 then knowing that the parabola's center is at a point 384m above the ground you can just add that to the equation, giving you y=-(x-16)^2+384.

Demons answer this for me.

denis-greek [22]

Answer:

Step-by-step explanation:

if you have negative numbers of x (this means negative meters) then the equation transform them into negative yards.

then replace y by 40yd in the equation like

40 = 1.09x

x = 40/1.09 = 36.7 meters

so in a 40yd race, there are 36.7 meters.

Tony walked 3 1/2miles in 7/8 of an hour. At this rate, how many miles can Tony walk in one hour?

Rufina [12.5K]

Answer:

4 miles

Step-by-step explanation:

The problem gives you your rate. Use the rate that is given to you and then multiply that by 1

$1 * (\frac{3.5}{\frac{7}{8}} ) = 4$

Tony can walk 4 miles in one hour

Ellie needs new grass in the circular pen for her chickens. There is 175.84 feet of fencing around the circular pen. What is the

pshichka [43]

<h3>Area of pen is 2462 square feet</h3>

<em><u>Solution:</u></em>

Given that,

Ellie needs new grass in the circular pen for her chickens

There is 175.84 feet of fencing around the circular pen

Therefore,

Circumference = 175.84 feet

<h3><u>The circumference of circle is given as:</u></h3>

$C = 2 \pi r$

Where, "r" is the radius of circle

$175.84 = 2 \times 3.14 \times r\\\\175.84 = 6.28 \times r\\\\r = \frac{175.84}{6.28}\\\\r = 28$

<h3><u>The area of circle is given as:</u></h3>

$Area = \pi r^2\\\\Area = 3.14 \times 28^2\\\\Area = 3.14 \times 784\\\\Area = 2461.76 \approx 2462$

Thus area of pen is 2462 square feet

If data set A has a smaller standard deviation than data set B, what would be different about their distributions?

Aleksandr-060686 [28]

Answer:

Data set B would have flatter distribution with more data in each tail.

Step-by-step explanation:

We are given the following in the question:

Data set A has a smaller standard deviation than data set B.

$\sigma_A < \sigma_B$

Standard Deviation:

It is a measure of dispersion of data.
It tells us about how much the data deviates around the mean.
It tells us about the overall deviation of the data from the mean.
The standard deviation is small when the data are all close to the mean showing less variation.
The standard deviation is larger when the data values are farther away from the mean, showing more variation.

Since data A has less standard deviation than data B, then data B has a flatter graphical representation as more of the data are present on the tails.
