t= 2.25 secs

Step-by-step explanation:

Step 1 :

Equation for motion with uniform acceleration is v = u+ at

where v is the final velocity

          u is the initial velocity

          a is the acceleration due to gravity

          and t is the time

Step 2 :

Here , v = 0 because at the highest point final velocity is 0.

u = 72 feet/sec

a = -32 ft/sec^2

We need to find the time t.

Substituting in the equation we have,

0 = 72 -32 * t

=> 32 t = 72

=> t = 72/32 = 2.25 secs

Can you help me with 4 through 6 plz

Example 4:

Let y = ax + b

Where, a = 4

Then,

y = 4x + b

As we have one point = (-2,3)

Replace in the equation:

3 = 4(-2) + b

3 = -8 + b

b = 3 +8

b = 11

So us stay:

y = 4x + 11
________________

Now let's to the 5 example:

Let y = ax + b

Where a = 3/2

Then,

y = 3x/2 + b

As the point is = (4, 7)

Then we will stay:

7 = 3(4)/2 + b

7 = 6 + b

b = 7 - 6

b = 1

Then we will stay:

y = 3x/2 + 1
______________


Now let's to the last example:

Let y = ax + b

Where , a = -4/3

Then we going to stay with:

y = -4x/3 + b

As the point is = (6 , -2)

Then,

-2 = -4(6)/3 + b

-2 = -8 + b

b = -2 + 8

b = 6

So follow:

y = -4x/3 + 6


I hope this helped!

The numbers from 1 to 150, inclusive, are placed in a bag and a number is randomly selected from the bag. What is the probabilit
Ivan

Answer:

139/150

Step-by-step explanation:

Let's make a list of the perfect squares.

1 4 9 16 25 36 49 64 81 100 121 144

The probability that one of these is drawn is 12/150 = 4/50 = 2/25

Take out 1. So that means there are 11 perfect squares.

11/150 are your chances of getting a perfect square.

1 - 11/150 = 139/150 that you will not get a perfect square.

I would have included 1 in the perfect squares, but the question says not to so you can't.

If the question did not mean that 1 should be excluded, then the answer is 23/25

Frame the polinomial whiose sum product of zeros are -3and2​
Virty [35]

Answer:

P(x) =x² + 3x + 2  

Step-by-step explanation:

You have two zeros, so the polynomial is a quadratic.

The general form of a quadratic is

P(x) = ax² + bx + c

     Sum of zeros = -b

Product of zeros =   c

The polynomial becomes

P(x) = x² - (sum of zeros)x + (product of zeros)

Sum of zeros = -3 and product of zeros = 2, so

P(x) = x² + 3x + 2

The graph of P(x) (below) shows that the zeros are at -2 and -1

     Sum of zeros = -2 + (-1) = -3

Product of zeros = -2 × (-1) =   2

Dvinal [7]

Answer:

t=7,t=0

Step-by-step explanation:

2t^2-14t+3=3

Subtract 3 from both sides

2t^2 - 14t +3 - 3 = 3-3

Simpilfy

2t^2 -14t = 0
