nes a height
A ball is kicked from a height of 2 feet off the ground. After 1 second the ball reaches a height of 22 feet, and it reaches its maximum height of 38 feet after 3 seconds.
• Write the quadratic equation that represents the height of the ball at any given time
• Find the height of the ball at 4 seconds
Solve the following quadratic equations

Answers

Answer 1

Answer:

y = - 2x + (1/2 38) + 2   = y =  -2x + 19x + 2  at any second  and y = -2x^2 / 2  + 19/2 + 2/2 = - x^2 + 19/2 + 2 =  - x (4) + 19/2(4) + 1 = -4+ 38 + 1 = 35 seconds  

Step-by-step explanation:    We see that 38-2ft = 36ft and y intercept  = 2 and then -2x allows us to represent the starting point 2 as -2 (1) to allow a descend to our back to 0 for y  one we find y intercept we know - x^2  is our simplified equation and an input into this to find the static and slowed descend back to 0  if you keep inputting at 5 and 6 you see the equation speed up   Anyway at (4) substitute = 4 seconds we divide our simplified equation a = -x2 into  a b c and divide each by 2  before working out the decline of the equation (as equation still represents all ascending and descending) for the 4th second as the height was already said to be at its max at 38 feet see equation in answer to find 4 as substitute for x

Nik needs to estimate how many books will fit in a bin. Each book is 0.75 feet tall, 0.75 feet wide, and 0.25 feet thick. The bin is 4 feet wide, 4 feet tall, and 4 feet deep. Based on volume only, about how many books will fit in the bin?

Answers

Step-by-step explanation:

first you find the volume of a bin.

that is multiplication of 3 dimensions given.

4*4*4=64 cubic feet...

now volume of books..

0.75*0.75.0.25=0.14 cubic feet

now the number of books that will fit the bin=volume of bin/volume of books

64/0.14=455

455 books

We want to see how many books can fit in a bin, given that we know the dimensions of the books and the bin. We will see that 457 books can enter in the bin.

Remember that the volume of a rectangular prism of length L, width W, and height H is just given by:

V = L*W*H

Here we know that each book is:

0.75ft by 0.75ft by 0.25ft

Then the volume of a single book is:

V = 0.75ft*0.75ft*0.25ft = 0.14 ft^3)

While the bin is 4ft by 4ft by 4ft, thus its volume is:

V ' = 4ft*4ft*4ft = 64ft^3

The number of books that fit in the bin is given by the quotient between the bin's volume and the book's volume:

N = (64ft^3)/(0.14 ft^3) = 457 books.

Hi! ❤️ , im looking for some help here. ill give brainliest if able to.

Answers

Answer:

A. 2^11

Step-by-step explanation:

(They are basically asking what's 2^4 × 2^7, but with more words.)

I usually do each exponent individually:

2^4 is the same as 2 × 2 × 2 × 2 = 16 (or you could have read the text to figure that out)

2^7 is the same as 2 × 2 × 2 × 2 × 2 × 2 × 2 = 128

Then just multiply 128 and 16 to get 2,048, and see which option also gives you 2,048.

BUT, you can also:

(Combine the exponents together to get your answer. Just remember that if it's multiplication you add them, and if it's division you subtract them.)

2^4 × 2^7

4 + 7 = 11

2^11 (This equals 2,048 btw. You don't even have to check all the options to get the answer).

You have found the following ages (in years) of all 5 porcupines at your local zoo:

16,10,5,7,13

What is the average age of the porcupines at your zoo? What is the standard deviation? Round your answers to the nearest tenth.

Answers

Answer:

Average is 10.2 standard deviation is 3.4

Step-by-step explanation:

To find the average age, add all the value together then divide by the amount added. (5 + 7 + 10 + 13 + 16) / 5

Standard deviation is average distance from average of each number. 10.2-5, etc…

The average age of the porcupines at the zoo is 10.2 and the standard deviation is 4

What is Standard Deviation?

The term "standard deviation" (or "") refers to a measurement of the data dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Standard Deviation is calculated by

Each number's deviation from the mean must be determined, and then squared.Next, add up all of these values.Divide the result by the quantity of numbers.Then calculate its square root.

Given data ,

The set of ages of porcupines in zoo be S = { 16 , 10 , 5 , 7 , 13 }

The average of these numbers in set S is the sum of all the numbers divided by the number of elements in the set

So , Average age of the porcupines = ( 16 + 10 + 5 + 7 + 13 ) / 5

                                                            = 51 / 5

                                                            = 10.2

Therefore , the average age of the porcupines at the zoo is 10.2

The standard deviation is calculated by

Step 1 : Each number's deviation from the mean must be determined, and then squared.

( 16 - 10.2 )² + ( 10 - 10.2)² + ( 5 - 10.2 )² + ( 7 - 10.2 )² + ( 13-10.2 )²

= ( 5.8 )² + ( -0.2 )² + ( -5.2 )² + ( -3.2 )² + ( 2.8 )²

= 33.64 + 0.04 + 27.04 + 10.24 + 7.84

= 78.8

Step 2 : Divide the result by the quantity of numbers.

78.8 / 5

= 15.76

Step 3 : Then calculate its square root.

√15.76

= 3.96

≈ 4

Hence , the standard deviation is 4

Step-by-step explanation:

(x – 7)^2 = 36

Take the square root of each side

x-7 = ±6

x-7 = 6         x-7 =-6

Add 7 to all sides

Answer:

  y = 3x +5

Step-by-step explanation:

The given form of the equation for a line is "slope-intercept" form. In order to use it, you need to know the slope of the line, and its y-intercept.

The y-intercept is where the line meets the y-axis. Here, that is halfway between 4 and 6, so we estimate the value to be b = 5.

The slope is the rise divided by the run. For x=1, the line has a point at (1, 8). That is 3 units above and 1 unit right of the point on the y-axis. Then the slope is ...

  m = rise/run = 3/1 = 3

For a slope of 3 and a y-intercept of 5, the equation of the line is ...

  y = mx +b . . . . . . slope m, y-intercept b

  y = 3x +5
