Dafna11 [192]

Answer:

1 and 3

Step-by-step explanation:

Let functions be

Jada = f(j)
Diego = f(d)
Lin = f(l)

As per given ratios:

f(d) = 2f(l)
f(j) = 2f(d) ⇒ f(j) = 4f(l)

The smallest slope belongs to f(l), greater - f(d), the greatest - f(j)

Possible graphs reflecting the functions are graph 1 and graph 3

Hi. I need help with these questions (see image) Please show workings.

pantera1 [17]

Answer:

see explanation

Step-by-step explanation:

Using the chain rule

Given

y = f(g(x)), then

$\frac{dy}{dx}$ = f'(g(x)) × g'(x) ← chain rule

and the standard derivatives

$\frac{d}{dx}$ ( $log_{a}$ x ) = $\frac{1}{xlna}$ , $\frac{d}{dx}$ (lnx) = $\frac{1}{x}$

(a)

Given

y = $log_{a}$ $\sqrt{(1+x)}$

$\frac{dy}{dx}$ = $\frac{1}{lna\sqrt{(1+x)} }$ × $\frac{d}{dx}$ ( $(1+x)^{\frac{1}{2} }$

= $\frac{1}{lna\sqrt{(1+x)} }$ × $\frac{1}{2}$ $(1+x)^{-\frac{1}{2} }$ × $\frac{d}{dx}$ (1 + x)

= $\frac{1}{lna\sqrt{(1+x)} }$ × $\frac{1}{2\sqrt{(1+x)} }$ × 1

= $\frac{1}{2lna(1+x)}$

= $\frac{1}{(1+x)lna^2}$

(b)

Given

y = ln sinx

$\frac{dy}{dx}$ = $\frac{1}{sinx}$ × $\frac{d}{dx}$ (sinx)

= $\frac{1}{sinx}$ × cosx

= $\frac{cosx}{sinx}$

= cotx

4. Brett is fencing in a circular patio. The radius of the patio is 70 feet. How many linear feet of

skad [1K]

Answer:

The number of feet of fencing that he needs will be equal to the perimeter of the circular patio.

We know that the perimeter of a circle of radius R is equal to:

P = 2*pi*R

where pi = 3.14

Then if the radius of the patio is 70ft, the perimeter of the patio will be:

P = 2*3.14*70ft = 439.6 ft

Then he needs 439.6 ft of fencing to enclose the patio.
