The rate of increase (R) of the radius (r) in meters per second is inversely proportional to the radius. If the radius is increa
Mariana [72]

<em><u>The equation to the rate of increase of the radius in terms of the radius is:</u></em>

R = \frac{14000}{r}

<em><u>Solution:</u></em>

<em><u>The rate of increase (R) of the radius (r) in meters per second is inversely proportional to the radius</u></em>

Therefore,

R \propto \frac{1}{r}\\\\R = k \times \frac{!}{r} -------- eqn\ 1

<em><u>The radius is increasing at 1400 meters per second when the radius is 10 meters</u></em>

r = 10 m

R = 1400 meter per second

<em><u>Substitute in eqn 1</u></em>

1400 = k \times \frac{1}{10}\\\\k = 14000

<em><u>Substitute k = 14000 in eqn 1</u></em>

R = 14000 \times \frac{1}{r}\\\\R = \frac{14000}{r}

Thus the equation is found

Point B is on line segment AC. Given AB = 3x, BC =4x+8 and AC = 5x + 10, determine the numerical length of AC
Vlada [557]

Answer:

15

Step-by-step explanation:

determine the numerical length of AC

We know that Ac is equaled to ab and bc because they are the segements between ac  

                3x                                4x+8

A-----------------------------B----------------------------------C

|<----------------------------5x+10 --------------------------->|

AB + BC = AC

solving for x

3x + 4X + 8 = 5X + 10

3x+4x-5x= 10-8

2x=2

x=1

Now sub that in for ac

AC= 5x +10

AC= 5(1) +10

AC= 5 +10

AC = 15

Does this graph represent a function? Why or why not?
Molodets [167]

Answer:

D

Step-by-step explanation:

This function passes the vertical line test.

The vertical line test test is done by drawing a vertical line anywhere on the graph. If the line goes through two points or more then it isn't a function.
