Answer: plants are same height in 30 days; Plant A is tallest in 6 weeks

Step-by-step explanation:

x = number of days

4 + (2/3)x = 9 + (1/2)x

(2/3)x - (1/2)x = 9 - 4

(1/6)x = 5

x = 30, number of days for Plant A and Plant B to be same height.

6 wks = 42 days

Plant A in 42 days: 4 + (2/3)(42) = 32 inches

Plant B in 42 days: 9 + (1/2)(42) = 30 inches

Is y = 1/x linear or non linear

Fofino [41]

Answer: This answer is non-linear.

Step-by-step explanation:

The problem $y=\frac{1}{x}$ has Vertical Asymptotes,

Horizontal Asymptotes,

and No Oblique Asymptotes making, $y=0$ and $x=0$ .

A linear function is a form of $y=mx+b$ .

This answer would be <u>non-linear</u>

Find the volume of the solid of revolution formed by rotating the bounded region about the x-axis.

nevsk [136]

Answer:

5.333 \pi

Step-by-step explanation:

Given is a function exponential as

$f(x) = \frac{x^2}{4}$

The region bounded by the above curve, y =0 , x=4 is rotated about x axis.

The intersection of curve with x axis is at x=0

The limits for x are 0 and 4

The volume when rotated through x axis is found by

$\pi\int\limits^b_a {f(x)^2} \, dx$

Here a = 0 and b =4

volume = $\pi\int\limits^4_(0) \frac{x^2}{4} \, dx$

= $\pi (\frac{x^3} }{12} )\\= \frac{\pi}{12} (64-0)\\= 5.333 \pi$
