h(4)=(gof)(4)=g(f(4)) so you must find f(4) first.

f(4)=  \frac{1}{4-3} =1

h(4)=(gof)(4)=g(f(4))=g(1)

So you look at what g(1) is?

g(1)=1^2+3=4

Therefore, h(4)=4

Image of parabola with a maximum value at (1, 9), y-intercept at (0, 8) and x-intercepts at (2, 0) and (4, 0).
natka813 [3]

Answer:

  (a)  4 seconds

Step-by-step explanation:

The given point (4, 0) on the parabola tells you the answer to the question: the coin was in the air 4 seconds before its height is 0. It is no longer in the air at that point.

Vadim26 [7]

Answer:

(7,2)

Step-by-step explanation:

x + y = 9 + 2x - 3y = 8 is really two equations, and you should show this by separating x + y = 9 from 2x - 3y = 8 through the use of a comma, or the word "and," or through writing only one equation per line.

Here you have the system of linear equations

 x +   y =  9

2x - 3y = 8.

Let's solve this system by elimination.  Mult. the 1st eqn by 3, obtaining the system

3x + 3y = 27

2x - 3y =    8

-------------------

5x = 35, so that x = 7.  Subbing 7 for x in x + y = 9, we get 7 + y = 9, indicating that y = 2.

Thus, the solution to this system of equations is (7,2).

sergeinik [125]
The answer is lizeth earns 0.35 cents more per hour. beacuse 66 divided by 8 =8.25 then 68.80 divided by 8 is 8.60 then if you subtract 8.60-8.25 it equals 0.35
