HURRY 20POINTS AND BRAINLIEST
Kareem threw a basketball from the basketball court toward the hoop. The function that models the height, in
feet, of the ball after a seconds is h(t) = -16t^2 +12t +8 If the hoop is 10 feet high, how long is the
ball in the air before it goes through the hoop?

Answers

Answer 1

Answer:

1/2 of a second

Step-by-step explanation:

Given function:

h(t) = -16t^2 +12t +8

Finding the value of t when h(t) = 10 feet:

10 = -16t^2 +12t +8-16t^2 +12t - 2 = 08t^2 - 6t + 1 = 0t = (6 ± √6²-8*4)/16 = (6 ± √4)/16 = (6 ± 2)/16 t = 1/2t = 1/4

There are two solutions. 1/2 of a second would be the answer as the ball should go up and then down to go through the hoop.

B. 31.62

Step-by-step explanation:

First, find the distance of the line using the distance formula, [tex]d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1} )^2 }[/tex]. Plug the two points (-1,0) and (5,2) into the formula and solve. This gives you 6.32, then this is only one line of a pentagon, which has 5 sides, so you need to multiply. Since you are finding the perimeter, which is all of the sides added together, multiply the one side by 5. 6.32*5=31.62.

A bench is located where the shadows casted by a 16 foot tall flagpole and 40-foot tall tree meet. If the bench is 18 feet from the flag pole, find the distance from the flagpole to the tree

Answers

Answer:

The distance from the flagpole to the tree is 27 ft

Step-by-step explanation:

Similar Triangles

Since the elevation angle from which the trees cast their shadows has the same measure and given the tree and the flagpole and the ground form right angles, both triangles are similar.

Similar triangles have their corresponding side lengths proportional. The ratio between the distances from the bench to the tree and flagpole and their heights is constant, i.e.:

[tex]\displaystyle \frac{16}{18}=\frac{40}{x}[/tex]

Where x is the distance from the bench to the tree.

Solving for x:

[tex]\displaystyle x=40\cdot \frac{18}{16}[/tex]

x = 45 feet

Thus the distance from the flagpole to the tree is 45 - 18 = 27 feet

Please help me if u give me an answer could u also give me an explanation on why that’s the answer.

Answers

so it’s A

in all the other ones we can see that the angles in the same position as x and 75 are all equal

and because the question tells us that they are all structured the same with p and f being parallel we can assume x is equal to what’s congruent to it

there is a rule that states this

cap congruent angle postulate i believe

which states that if two parallel lines are cut by a transversal, then corresponding angles are congruent

(Write an equation to go with the problem) Miranda goes to the store to buy 3 apples and some rice. The total was 6.50. If the rice cost $5.00, what was the cost per Apple?

Answers

Answer:

14.15 is the answer..comment it if that subtraction or multiple division

Answer:   3x + 5 = 6.50  is the equation where x represents the cost per apple and the cost per apple is 50 cents.

Step-by-step explanation:

In this situation we will represent the cost per apple by the variable x.

If she bought 3 apples, then 3 has to be multiply by x to find the cost so we will have the expression 3x

The rice cost $5  and she spend a total of 6.50  so  3x has to be add to 5 and it has to equal 6.50.

3x + 5 = 6.50  You can now solve for x in the equation to find the cost per apple

3x + 5 = 6.50

     -5       -5

 3x = 1.5

x= 0.5  

This means  the cost of an apple is 50 cents.

m<S=66.5

Step-by-step explanation:

The sum of the angles = 360

(6x-6)+(4x-10)+(5x-11)+(5x+13)+(4x+2) = 360

24x-12=360

24x=372

x=15.5

S=5x-11 = 5*15.5-11=66.5

Answer:

104

we have:

6x - 6 + 4x - 10 + 5x - 11 + 5x + 13 + 4x + 2 = 180.3

<=> 24x - 12 = 540

<=> 24x = 552

<=> x = 552/24

<=> x = 23

with x = 23, we have: m<S = 5.23 - 11 = 115 - 11 = 104
