Step-by-step explanation:

hello,

Replace x by the value as below

$g(3)=3^2-4\times3=9-12=-3\\f(g(3))=f(-3)=4\times(-3)-1=-12-1=-13\\$

Simplify 2 to the 5 power to the fourth power over 3 to the second power

melisa1 [442]

I'm assuming you mean 2^(5)(4/3)(2).
So multiplying all of the powers together yields 2^(40/3)

Find the maclaurin series for f(x) using the definition of a maclaurin series. [assume that f has a power series expansion. do n

Nady [450]

The equation of $f(x) = e^{-6x}$ by maclaurin series is $f(x)=\sum_{i=0}^{\infty} \frac{(-6.x)^{i} }{i!}$ .

The maclaurin series for f(x) is defined by the following formula:

$f(x) = \sum_{i=0}^{\infty} \frac{f^{(i)} (0)}{i!} .x^{i}$ --------------(1)

Where $f^{i}$ is the i - th derivative of the function

If f(x) = $e^{-6x}$ , then the formula of the i - th derivative of the function is:

$f^{i} =(-6)^{i} .e^{-6x}$ ----------------------(2)

Then,

$f^{i}(0) = (-6)^{i}$

Lastly, the equation of the trascendental function by Maclaurin series is: $f(x)=\sum_{i=0}^{\infty} \frac{(-6)^{i}.x^{i} }{i!} \\f(x)=\sum_{i=0}^{\infty} \frac{(-6.x)^{i} }{i!}$ ---------------(3)

Hence,

The equation of $f(x) = e^{-6x}$ by maclaurin series is $f(x)=\sum_{i=0}^{\infty} \frac{(-6.x)^{i} }{i!}$ .

3 PART QUESTION!

Illusion [34]

Answer:

See below

Step-by-step explanation:

<u>Given relationship:</u>

d = rt

a) r = 3, d = 4

t = d/r = 4/3 h = 1 h 20 min

b) d = 4 miles, rate = r

t = 4/r, domain is r and must be greater than zero

c) d = 4 miles, time = t

r = d/t = 4/t, domain is t and it must be greater than zero

d) t = 3 h, rate = r

d = rt = 3r, domain is r and can be anything greater than zero
