Find the perimeter of triangle PQR. Round your answer to the nearest tenth.
BabaBlast [244]
We are given the coordinate of the 3 vertices. From these coordinates we can find the length of the sides using the distance formula and the sum of all the sides will be equal to the perimeter of the triangle.

Side PQ = \sqrt{ (6-(-2))^{2}+  (1-1)^{2} }=8

Side QR = \sqrt{ (4-6)^{2}+ (-3-1)^{2} }=4.5

Side RP = \sqrt{ (2-(-4))^{2}+ (-3-1)^{2} }=7.2

So, the perimeter of the triangle will be 8 + 4.5 + 7.2 = 19.7 

You probably misplaced the digits in option A. The correct answer is 19.7 units.

After a special medicine is introduced into a petri dish full of bacteria, the number of bacteria remaining in the dish decrease
Crazy boy [7]

Answer:

  0.17

Step-by-step explanation:

The function can be rewritten as ...

  B(t) = 9300·((1/2)^6)^t = 9300·(1/2)^(6t)

In order to multiply the number of bacteria by 1/2, the value of the exponent 6t must be equal to 1:

  6t = 1

  t = 1/6 ≈ 0.166667 ≈ 0.17

The culture loses half its size every 0.17 seconds.

Interpret the average rate of change of –14/3 that you found previously. What does this mean in terms of the waterslide, from x
Yanka [14]

Answer:

Solution: The average rate of change of  represents that the second variable is decrease by 14 if the first variable increase by 3. In terms of water slide the vertical height of slide is decreased at the rate of 4.66 per unit. The vertical height of the slide decrease 70 units from x = 0 to x = 15.

Explanation:

The rate of change shows the change in first variable with respect to change in second variable.

If the rate of chang is given by  it means second variable is decrease by 14 if the first variable increase by 3.

In the context of water slide it shows that the vertical height of slide is decreased by 14 units as we cover the distance of 3 units.

If we cover the distance from x = 0 to x = 15, it means we cover the distance of 15 units.

Let the vertical height of the slide covered from x = 0 to x =15 be y.

It means when distance increased by 15 units the height of slide decreased by y units.

So rate of change = .

It is given that the rate of change is .

Equate both equations.

Therefore, the average rate of change of  represents that the second variable is decrease by 14 if the first variable increase by 3. In terms of water slide the vertical height of slide is decreased at the rate of 4.66 per unit. The vertical height of the slide decrease 70 units from x = 0 to x = 15.
