100 BRAINLY POINTS

Mathematics
1 answer:
ella [17]2 years ago
7 0

Answer:

  • After 17 years and 3 months

Step-by-step explanation:

<u>Given function:</u>

  • f(x)=18000(0.88)^x

We are looking for the value of x at f(x) < 2000

<u>Solve the equation:</u>

  • 2000 = 18000(0.88)^x
  • (0.88)^x = 2000/18000
  • (0.88)^x = 0.1111
  • log (0.88)^x = log 0.1111
  • x = log 0.1111 / log 0.88
  • x = 17.18

After 17 years and 3 months the car value drops below $2,000

The graph for the equation y=-2x+1 is shown below.
Tpy6a [65]

Answer:

Step-by-step explanation:

Given the equation y=-2x+1 and given another equation y=mx+b in order for us to have no solution we must guarantee that both lines do not intersect. Recall that m is the slope of the second equation and b the y-intercept. To guarantee that both lines don't intersect, they must be parallel. To have this result, we must have that they have the same slope but different y intercept. That is take m = -2 and b any value different to +1. For example, the b = 6. So

y = -2x+6 = -2(x-3) is another equation that gives no solution to the system.

Using the given information, give the vertex form equation for each parabola.
ollegr [7]

Answer:

Step-by-step explanation:

If you plot this point and the directrix on a coordinate plane, you can see that the directrix is 1/4 of a unit below the vertex.  Since, by nature, a parabola opens in the direction opposite the directrix and "hugs" the focus, this is a positive x-squared parabola (meaning it opens upwards).  The formula for this type of a parabola is, in vertex form,

4p(y-k)=(x-h)^2

where p is distance (in units) between the vertex and the directrix and h and k are the coordinates of the vertex.  For us, p = .25, h = 7, and k = -6.  Filling in our formula:

4(.25)(y+6)=(x-7)^2

Simplify the left side to

1(y+6)=(x-7)^2 which simplifies, in its entirety, to

(x-7)^2-6=y
