The height y (in feet) of a punted football is given by -16/2025x^2 + 9/5x + 2.5 where x is the horizontal distance (in feet) from the point at which the ball is punted. (a) How high is the ball when it is punted?
(b) What is the maximum height of the punt? (Round your answer to two decimal places.)
(c) How long is the punt? (Round your answer to two decimal places.)

Answers

a) The ball is 2.5 feet high when it is punted ( for: x=0 )
b) The maximum height ( formula for the parabola):Ymax= $(4ac-b^(2) )/(4a)= (4* (-16)/(2025)*25- (9)/(5)^(2) )/(4* (-16)/(2025) )$
Finally: Ymax= 105.02 feet.
c)We will find how long is the punt with the formula:
$- (16)/(2025) x^(2) + (9)/(5)x +2.5=0$
We will multiply it by 2025 to avoid the fractions:
$-16 x^(2) +3645x+5062.5=0$
And we will solve it:
$x_(12) = \frac{-b\pm \sqrt{b^(2) -4ac} }{2a}= (-3645\pm √(13286025+324000) )/(-32) x_(1)= (-3645-3689.1767)/(-32)$
x=229.19 feet.
We will except this answer because another one is negative.

Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which best describes the discriminant and the number of zeros? The equation has one zero because the discriminant is 1. The equation has one zero because the discriminant is a perfect square. The equation has two zeros because the discriminant is greater than 0. The equation has no zeros because the discriminant is not a perfect square.

Answers

The correct option is: The equation has two zeros because the discriminant is greater than 0.

Explanation:

First, remember the following conditions:
1. If the discriminant is less than zero, there will be no zeros.
2. If the discriminant is equal to zero, there will be one zero.
3. If the discriminant is greater than zero, there will be two zeros.

For the general equation of the form $ax^2 + bx + c = 0$ , the discriminant is $b^2 - 4ac$ .

Let's find the discriminant and then compare it with the conditions mentioned above.

Given Equation:
$3x^2 -7x + 4 =0$

a = 3, b = -7, c = 4

Now find the discriminant:

$b^2 - 4ac$
$(-7)^2 - 4(3)(4)$
Discriminant = 1

As the discriminant is greater than 0 (which in this case is 1), the equation has two zeros (as mentioned in the above conditions).

Solve for the variable in 7 ∕28 = 25∕ x A. 20 B. 100 C. 4 D. 5

Answers

The solution to the equation 7/28 = 25/x is x = 100.

What is the solution to the equation?

Given the equation in the question:

7/28 = 25/x

To solve for the variable x in the equation 7/28 = 25/x, first, we cross multiply.

7/28 = 25/x

Cross-multiplying, i.e multiplying the numerator of the first fraction with the denominator of the second fraction and vice versa:

Hence:

7 × x = 28 × 25

7x = 700

Now, isolate x by dividing both sides by 7:

7x/7 = 700/7

x = 700/7

x = 100

Therefore, x has a value of 100.

Option B) 100 is the correct answer.

2. The height of one solid limestone square pyramid is 24 m. A similar solid limestone square pyramid has a height of 30 m. The volume of the larger pyramid is 16,000 m3. Determine each of the following, showing all your work and reasoning. The ratio of the area of the base of the smaller pyramid to the larger pyramid (c) Ratio of the volume of the smaller pyramid to the larger (d) The volume of the smaller pyramidPlease help...LOTS OF POINTS

Answers

If you change the ratio ( doesn't affect V) , The pyramid will still be the same because when the ratio is change , moved , or becomes the independent variable nothing ever in a situation like this will change or alter in the experiment.

so i believe that the answer is C.) Smaller.

I really hope that this helps

i think it is c because it says that the is larger but its not the volume its the ratio so change the ratio to a volume and the volume is still bigger than the ratio given

Hopes this helps
