The base of a triangle is shrinking at a rate of 11 cm/s and the height of the triangle is increasing at a rate of 11 cm/s. Find
Mumz [18]

Answer:

the rate of changes  of the area of the triangle

\frac{dA}{dt}  = -11 cm^2 /sec

Step-by-step explanation:

<u>Explanation</u> :-

The area of triangle( A) = \frac{1}{2} base X height    ..........(1)

Let 'b' be the base and 'l' be the length of the triangle

The base of a triangle is shrinking( means decreasing) at a rate of 11 cm/s

that is \frac{db}{dt} = -11cm/sec

The height of a triangle is increasing at a rate of 11 cm/s

that is \frac{dh}{dt} = 11cm/sec

Given h= 10cm and b = 8cm

<u>The rate of change of triangle </u>

applying uv formula  \frac{d(uv)}{dx} = u( \frac{dv}{dx}) + v(\frac{du}{dx} )

Differentiating equation (1) with respective to 't'

\frac{dA}{dt} =\frac{1}{2}  ( b(\frac{dh}{dt} )+h ( \frac{db}{dt}))

substitute all values in above equation, we get

h= 10cm , b = 8cm , \frac{db}{dt} = -11cm/sec and \frac{dh}{dt} = 11cm/sec

 \frac{dA}{dt} = 10 (-11) + 8(11 )

After simplification , we get

\frac{dA}{dt} =\frac{1}{2}  (-110 +88) = -11 cm^2 /sec

Can anybody help me please? I'll give brainlest for correct answer​
Hoochie [10]

Answer:

1) 40 degrees

2) 140 degrees

3) 110 degrees

4) 70 degrees

5) 70 degrees

Explanation:

Use the curved protractor they have created you, and count every dash as 10 degrees. Keep in mind that the whole thing equals 180 degrees, and half would equal 90 degrees. Some call it a right angle.

Let me know if my answer is correct for the other users that will see this message. Thank you!
