A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by th

Blababa [14]

Answer:

Step-by-step explanation:

so when the height is zero, that's when the rocket hits the ground. The equation will have two zeros, but one would be for a negative time, or before the rocket is launched. so we only one the one after the rocket is launched.

use the quadratic formula to solve for x ( which is time)

-124 +- sqrt [ $124^{2}$ - 4*(-16)*(127) ] / 2 (-16)

-124 +- sqrt [15376 + 8128 ] / -32

-124 +- sqrt [23504 ] / -32

-124 +- 153.310 / -32

if we take the positive part it will become the negative time so skip that one try the negative part 1st

-124 - 153.310 / -32

-277.310 / -32

8.6659 seconds to hit the ground. ( time of flight) aka TOF

8.67 seconds ( rounded to nearest 100th)

You run a hotel with 1465 rooms. You currently have 296 rooms reserved by individuals and 651 rooms reserved by groups for a par

Tanya [424]

Answer:

Hotel is over booked by 140 rooms

Step-by-step explanation:

Total number of hotel rooms = 1465

number reserved by individuals = 296

number reserved by groups = 651

booking rates = 67% for individual , 56% for groups

Determine if you are under booked or overbooked for the weekend

let X represent the number of rooms booked by individuals

and Y represent the number of rooms booked by groups

number of reserved room for individuals

= 67% of X = 296

X = 67% + 33%

= 296 + ( (296 / 67 ) * 33 )

= 296 + 146 ≈ 442

number of rooms reserved for groups

= 56% of Y = 651

Y =( 651 / 56 ) * 100

≈ 1163

Total rooms booked = X + Y

= 442 + 1163 = 1605

To determine if under booked or over booked

Total rooms booked - Total number of hotel rooms

= 1605 - 1465

= 140 ( Your Hotel is over booked )

-1 - (-4) = 3

17.
-1-1/3 - (-4) = 2-2/3

18.
2 - (-1) = 3

19.
3-1/2 - (-1) = 4-1/2

20.
3-1/2 - 2 .= 1-1/2

21.
3-1/2 - (-1-1/3) = 4-5/6

Step by step: I took one point and subtracted the second point to get the length of each segment. You could also look at the ruler and count from one point to the other.

Remember when you subtract a negative, the two negatives become a positive
