1. Write the equation for a line in point slope form that had a slope of 4 and passes through (1,1)

Dahasolnce [82]

Solution:

Slope = m = 4
Given point: (x₁,y₁) = (1,1) [x₁ = 1; y₁ = 1]
Formula: y - y₁ = m(x - x₁)

<u>Use the formula to convert the line in point slope form.</u>

y - y₁ = m(x - x₁)
y - 1 = 4(x - 1)

The equation of the line (In point slope form) is y - 1 = 4(x - 1).

An engine cylinder 13.7 cm deep is being bored such that the radius increases by 0.13 mm divided by min. How fast is the volume

zzz [600]

Answer:

Step-by-step explanation:

Given that an engine cylinder 13.7 cm deep is being bored such that the radius increases by 0.13 mm divided by min.

We convert everything in mm for uniformity

We have formula for volume as

$V=\pi r^2 h$

Given that $\frac{dr}{dt} =0.13$

h is constant

$V= 3.14 (r^2) (13.7)\\\frac{dV}{dt} =6.28 (137) r dr/dt\\= 6.28(137)\frac{ (97)}{2} 0.13$

= 6954.67 mm/sec^3

Differentiate with respect to x : 2xe^x

Gnom [1K]

$\\ \sf\longmapsto \dfrac{d}{dx}2xe^x$

Apply product rule

$\\ \sf\longmapsto \dfrac{d}{dx}2x(e^x)$

$\\ \sf\longmapsto 2x\dfrac{d}{dx}e^x+e^x\dfrac{d}{dx}2x$

$\\ \sf\longmapsto 2xe^x+2e^x$

$\\ \sf\longmapsto 2e^x(x+1)$
