Answer:

(2x + 1)×3 = 1×(3x+4)

6x + 3 = 3x + 4

6x-3x = 4 -3

3x = 1

x = 1/3

The volume of a sphere is increasing at a constant rate of 141 cubic feet per minute. At the instant when the radius of the sphe

ch4aika [34]

Answer:

0.093 ft/min

Step-by-step explanation:

V = 4/3 π r³

Take derivative with respect to time:

dV/dt = 4π r² dr/dt

Plug in values:

141 = 4π (11)² dr/dt

dr/dt = 141 / (484π)

dr/dt ≈ 0.093

The radius is increasing at 0.093 ft/min.

Coordinates (-3, 5), ( -3, 8), and (2, 5). The triangles was dilated by a scale favtor of 3. What is the area of the dilated tri

Otrada [13]

Answer:

The area of the triangle is 7.5 unit²

Step-by-step explanation:

Here we have the coordinates given as

(-3, 5) (-3, 8) and (2, 5)

Let us call the points A = (-3, 5)

B = (-3, 8) and

C = (2, 5)

Therefore the lengths of the sides of the triangle are

AB = a = $\sqrt{(-3-(-3))^2+(5-8)^2} = 3$

AC = b = $\sqrt{(-3-2)^2+(5-5)^2} = 5$

BC = c = $\sqrt{(-3-2)^2+(8-5)^2} = \sqrt{34}$

Therefore the Area can be derived from Heron's formula which is

A = $\sqrt{s\times (s-a)\times (s-b)\times (s-c)}$ where s = semi perimeter or (a + b + c)/2

Therefore, plugging the values, we get

s = (3 + 5 + √34)/2 = 6.9155≈6.92

A = $\sqrt{6.92\times (6.92-3)\times (6.92-5)\times (6.92-\sqrt{34} )}$ = 7.499≈7.5.
