Complete Question

A skier leaves a ski jump with a horizontal velocity of 29.4 m/s. The instant before she lands three seconds later, the magnitudes of the horizontal and vertical components of her velocity are: Group of answer choices

A 29.4 m/s; 29.4 m/s.

B 41.6 m/s; 41.6 m/s.

C 29.4 m/s; 41.6 m/s.

D 0; 29.4 m/s.

E 29.4 m/s; 0.

Correct option is A

Explanation:

From the question we are told that

     The horizontal velocity is  

      The time taken for the jump is

The velocity along the vertical axis is  

substituting values

During the jump the horizontal velocity remains the same as there was a direction change

So the correct option is  A

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

explanation:

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6
