Answer:

-6.21 x 10^5

Step-by-step explanation:

The negative only comes when the numbers are in the decimal to right such as 0.1 when its on the left side it just mean positive power such as 6.0= a positive, negative power = 0.6 count how many numbers there are (6) then get the last number as the whole number and the rest are behind (-6.21) count all the numbers besides the last number (6) now that is your power so you get -6.21 x 10^5

Select the correct answer from each drop-down menu. if f(x)=x^2+2x-3 and g(x)=x^2-9, find (f/g)(4) and (f+g)(4).
Nataly_w [17]

Answer:

(f/g)(4) = 3

(f + g)(4) = 28

Step-by-step explanation:

(f/g) = \frac{x^2+2x-3}{x^2-9}

(f + g) = 2x^2 + 2x -12

Simply plug in 4 for x in both equations to find you answer!

which of the folowing could be the equation for a parabola that opens to the left with vertex (-17, 2)
KATRIN_1 [288]

Answer:

x = a(y+17)^2 + 2 where a < 0

Step-by-step explanation:

Since the parabola is horizontal, the formula of the parabola is x = a(y-h)^2 + k where (h,k) is the vertex.

Since it opens to the left, a must be negative. The vertex is (-17, 2), so h = -17 and k = 2.

Substituting these in, we find that the equation is

x = a(y+17)^2 + 2 where a is a real number that is less than 0 (i.e. negative)

I hope this helps! :)
