Answer:

m = -3

Step-by-step explanation:

We can find the slope by using

m = (y2-y1)/(x2-x1)

We use two points

(0,-4) and (-2,2)

m = (2 - -4)/(-2 -0)

= (2+4)/(-2-0)

=6/-2

= -3

The radius of a circular puddle is growing at a rate of 25 cm/sec.

tatiyna

Answer:

Step-by-step explanation:

a)area A=pi r^2

rate of change of area =dA/dt =2 pi r dr/dt

given dr/dt =25 ,r =50

rate of change of area =dA/dt =2 pi *50 *25 =2500pi=7854

area growing 7854 cm2/s

b)area A=pi r^2

rate of change of area =dA/dt =2 pi r dr/dt

given dr/dt =25 ,A =64

pi r^2 =64

=>r =8/√pi

rate of change of area =dA/dt =2 pi *(8/√pi) *25 =400√pi=708.98

area growing 708.98 cm2/s

Answer:

y = 6.5

Step-by-step explanation:

When triangles are similar, we can set up a proportion to compare the sides. I will have the "left" side on the bottom of the fractions, and the side I am solving for on the top.

$\frac{y}{6} =\frac{13}{12}$

[Cross multiply]

12y = 78

y = 6.5

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
