A triangle has a height that is increasing at a rate of 2 cm/sec and its area is increasing at a rate of 4 cm2/sec. Find the rat
lesya [120]

Answer:

The value of rate of which the base is changing \frac{dB}{dt} = - 3 \frac{cm}{s}

Step-by-step explanation:

Area = 20 cm^{2}

height = 4 cm

\frac{dH}{dt} = 2 \frac{cm}{sec}

\frac{dA}{dt} =  2 \ \frac{cm^{2} }{sec}

we know that area of the triangle is given by

A= \frac{1}{2} B H

B = \frac{2A}{H}

B = \frac{2 (20)}{4}

B = 10 cm

Rate of change of area is given by

\frac{dA}{dT} = \frac{1}{2} [B\frac{dH}{dt} + H \frac{dB}{dt} ]

4 =  0.5 [10 × 2 + 4 \frac{dB}{dt} ]

\frac{dB}{dt} = - 3 \frac{cm}{s}

This is the value of rate of which the base is changing.

Evaluate the integral using integration by parts with the indicated choices of u and dv. (use c for the constant of integration.
Zolol [24]

Answer:

(7/3) x^3 ln x - (7/9) x^3 + c.

Step-by-step explanation:

∫udv = uv - ∫vdu

u = ln x and dv = 7x^2dx so,

du = 1/x and v = 7x^3/3 so:

∫7x^2 ln x = (7x^3/3) ln x - 7 ∫x^3/3 * 1/x dx

                 = 7/3 x^3 ln x - 7 ∫x^2/3 dx

                 = 7/3 x^3 ln x - 7/x^3/2 * 1/3 dx

                 = 7/3 x^3 ln x - 7/9 x^3 + c.
