Answer:

x intercepts there are three and y intercept in 0

Step-by-step explanation:

so  f(x)=a(0+3)(x-2)^2(x-2)

-2=a(3)(4)(-2)

-2=a(-10)

a=5

rewrite

f(x)=5(x+3)(x-2)^2(x-2)

An ant moves 18 millimeters every 5 seconds
vaieri [72.5K]

Answer:

Step-by-step explanation:

First we need to find their rate of speed.

r = d / t

For ant,

Convert millimeters to inches.

1 inch = 25.4 mm

18 mm = 0.7 inch

r = 0.7 / 5

r = 0.14 inches per second

For beetle,

r = 8 / 3

r = 2.7 inches per second

From the rates, you can tell that the beetle crosses the Garden first.

To know how long it takes for the ant to cross is by dividing the length by the rate.

1 yard = 36 inches

13 yards = 468 inches

468 ÷ 0.14 = 668.5 ≈ 669 seconds

In terms of minutes:

11 minutes and 15 seconds

The ant would cross the garden in 11 minutes and 15 seconds (or 669 seconds <em>up to you</em>).

The measure of two complementary angles are in the ratio 1 : 5. What are the degree measures of the two angles? What is the solu
ser-zykov [4K]
Ratio 1:5....added = 6
complimentary angles, when added, = 90 degrees

1/6(90) = 90/6 = 15
5/6(90) = 450/6 = 75

so ur 2 angles are : 15 and 75

 y = - 4x + - 8 is equation of slope-intercept form.

What is in slope-intercept form?

  • Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form.
  • Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.

the equation of slope - intercept form

                               y = mx + c

( -1 , -4 ) is point shown in graph

            slope = -y/x

                     = - ( -4)/-1  = 4/-1 = -4

             - 4 = -4 * - 1 + c

            - 4 = 4 + c

            c = - 4 - 4 = - 8

put value of c in the equation of slope - intercept form

             y = - 4x + - 8
