A ball is thrown into the air with an upward velocity of 100 ft/s. Its height, h, after t seconds is given by the function
h = -16t2 + 64t + 960.
What is the maximum height?
960 feet
1008 feet
1024 feet
1152 feet

Answer:

When the equation parallel the graph then the measure of the equation is - 3/4

Then the equation is y=-3/4x+c

By using the point(-2,3)

[tex] y = \frac{ - 3}{4} x + c \\ 3 = \frac{ - 3}{4} \times - 2 + c \\ 12 = 6 + 4c \\ 4c = 6 \\ c = \frac{3}{2} [/tex]

Then the equation is

[tex]y = \frac{ - 3}{4} x + \frac{3}{2} [/tex]

Answer:

x is 103 cause it is opposite angles and y is 77 180-103 hope this helps you

Answer: x=103° y=77°

Step-by-step explanation:

Opposite angles are always the same so, as x is opposite to 103°, it would be 103° too.

To work out what y is you would have to do 180-103=77°. The reason why is because angles on a straight line always add up to 180° and you can see that 103° and y are on the same line.

Hope this helps :)

Answer:

$90.75

Step-by-step explanation:

$2 (for each donut) x 11 (the number of donuts they want

=22

Then

$1.25(for each cookie) x 55 (the number of cookie they want)

=$68.75 +$22

Answer:

b(y-intercept)=(0,1) and M(slope)=-2

Step-by-step explanation:

use the slop formula and the slope intercept form to find the slope and y intercept. slope -2. y-intercept (0,1)

with that information, the equation would be y=mx+b. y=-2x+(0,1)

Answer:

Let 3x and 2x are divided into 250.

Step-by-step explanation:

3x + 2x = 250

⇒ 5x = 250

⇒ x =  = 50

∴ 3x = 3 × 50 = 150 and

2x = 2 × 50 = 100

Thus, the required numbers are 150 and 100.

Answer:

9/10

Step-by-step explanation:

To divide by 5/6, invert 5/6, obtaining 6/5, and then multiply:

 3         6

------ *  ----- = 18/20 = 9/10 (same as the 2nd possible answer)

  4        5

Answer:

Step-by-step explanation:

Plug in the giving information, P = 4000, r = 0.06, n = 4,

and t = 5.

Use the order or operations to simplify the problem. If the

problem has decimals, keep as many decimals as possible

until the final step.

FV = 5387.42  Round your final answer to two decimals places.

Answer:

Step-by-step explanation:

9y-4 = 50

9y = 54

y= 6

9y-4+7x+xy = 180

9(6)-4+7x+6x= 180

54-4+13x = 180

13x+50 = 180

13x = 130

x = 10

Answer:

(4,2)

Step-by-step explanation:

So proportional means that it is the same rate. I believe it is (4,2) because from 4 to eight is 4 and from 2 to 6 is also 4 and there for it is proportional.

Answer: 1) 8x + 2 = 90 1a. 11 2. 13x-10= 133 2a. 11

Both solve for 11.

Step-by-step explanation: 1) they’re both the same measure so they equal each other

Subtract 2 from each side 8x = 88 and x is 11

13x - 10 = 133 they’re both the same measures so they equal each other.

Add 10 to both sides because it’s already negative and 13x = 143 and you get 11

Answer:

11 for both

4.5 x 3.14= 14.13

ignore this- the other person got it right. I messed up and can't delete it. Sorry!

Step-by-step explanation:

the the coefficient of y in the above expression is A(1)

Answer:

50.24

Step-by-step explanation:

4 = radius

To get the diameter you need to multiply the radius by two  4 x 4 = 16 use 3.14 =  3.14 x 16 =  50.24 THERE IS THE ANSWER!!!!
