Answer: 85 / 7

Explanation

1) Slope formula

slope, m = rise / run = Δy / Δx = (y2 - y1) / (x2 - x1)

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

2) Data:

m = - 7 / 2

x1 = 13
y1 = 2

x2 = ?
y2 = 5

3) Replace the data in the formula and solve for the unknown:

  5 - 2           7
----------  = - ----- => x2 - 13 = - 2 * (5 - 2) / 7
x2 - 13          2

=> x2 = 13 - 2 (5 -2) / 7 = 13 - 2(3) / 7 = 13 - 6/7 = 85/7

Answer: 85 / 7

11Alexandr11 [23.1K]

Answer:

x = 25

Step-by-step explanation:

To find the value of x we use the formula:

tan x° = opposite side /adjacent side

Opposite Side = 8

Adjacent Side = 17

tan x° = 8/17

tan x° = 0.4705882352941

Tan^{-1} of 0.4705882352941

x° = 25

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
