If g (x) =x 1/x-2 and h(x) = 4 – x, what is the value of (g*h)(-3)?

1 answer:

4 0

G(x) = (x + 1)/(x - 2) and h(x) = 4 - x
(g * h)(x) = (x + 1)(4 - x)/(x - 2)
(g * h)(-3) = (-3 + 1)(4 - (-3))/(-3 - 2) = (-2)(4 + 3)/(-5) = (-2)(7)/(-5) = -14/-5 = 2.8

REY [17]

Answer:

Both will be at the same page after 6.5 days and the page number will be 180.

Step-by-step explanation:

Let after x days Nora and Lila will be at the same page.

Nora is on page 128 and plans to read 8 pages per day until the next club meeting.

After x days Nora will be at the page number = 128 + 8x

Similarly, Lila is on page 102 and she reads 12 pages per day.

After x days Lila will be on page number = 102 + 12x

Since after x days they will be at the same page

Therefore, 128 + 8x = 102 + 12x

12x - 8x = 128 - 102

4x = 26

x = $\frac{26}{4}$

x = 6.5 days

Page number they will be on = 128 + 8(6.5)

= 128 + 52

= 180

Both will be at the same page after 6.5 days and the page number will be 180.

The equation of a parabola is shown.

WARRIOR [948]

The axis of symmetry for this parabola is the x-axis. The general form of the equation is:
4p(x-h) = (y-k)^2
where the focus has the coordinates of (h+p,k)

Manipulating the given equation to the general form:
4(1/3)(x-7)^2 = (y - 0)^2

Therefore the coordinates of the focus is:
(7+(1/3),0)

The answer is A.) (71/3,0)
