She went 3.5 feet per second down for 90 seconds
3.5*90 = 315 feet below
2.2*30 = 66 feet up
315-66 = 249 feet below.

So, she must go up at 4.8 feet per second.
249/4.8 = 51.875 seconds
52 seconds when rounded

Answer:

1/4x^2 - 1/4x - 1/4

Step-by-step explanation:

I multiplied the two binomials at the top to get 6x^2 + x -2 and I divided it by 24x^2 - 4x - 8 and simplified it to get 1/4x^2 - 1/4x - 1/4

Please answer this question picture shown !!

The answer is choice D because the expression 6x^3+x^2-3 is the same as 6x^3+1x^2+0x+(-3). Notice the coefficients are 6, 1, 0, -3

The expression x-7 is in the form x-k where k = 7. This is the test root which is placed outside of the synthetic division bar as shown in choice D.

Answer:

Mean - 3.3793103448276

Median - 3

Step-by-step explanation:

Define:

Mean ⇒ Average

Median ⇒ Middle Number

Solve:

Mean ( Adding all number then divide by total number in data set)

1 + 1 + 2+2+2+2+3+3+3+3+3+3+3+3+3+4+4+4+4+4+4+4+4+5+5+5+5+5=94

94/29 = 3.3793103448276

Mean - 3.3793103448276

Median ( Find Middle Number)

1,1,2,2,2,2,3,3,3,3,3,3,3,3,3,4,4,4,4,4,4,4,4,4,5,5,5,5,5
