Answer:

A) 2x3 + 11x2 + 8x - 16.

Step-by-step explanation:

s(x).t(x) = (x + 4)( 2x2 + 3x - 4)

= x(2x2 + 3x - 4) + 4( 2x2 + 3x - 4)

= 2x3 + 3x2 - 4x + 8x2 + 12x - 16

= 2x3 + 11x2 + 8x - 16

Let g(x) = log7 (x),<br> find g ¹(0)

klasskru [66]

Step-by-step explanation:

The derivative of log is

$\frac{d}{dx} ( log_{a}(x) ) = \frac{1}{x \: ln(a) }$

You can easily derive this using the Change of base rule, and natural log rules

$log_{a}(x) = \frac{ log_{e}(x) }{ log_{e}(a) } = \frac{ ln(x) }{ ln(a) }$

Next, we differentiate with respect to x.

$\frac{d}{dx} \frac{ ln(x) }{ ln(a) } = \frac{1}{ ln(a) } \times \frac{d}{dx} ln(x)$

$= \frac{1}{x ln(a) }$

So back to the topic at hand,.

a=7, so we get

$\frac{1}{x ln(7) }$

We plug in 0, we would get undefined

If the ratio of the length to perimeter is 5:16 what is the area of the rectangle

salantis [7]

The area is 15
Multiply the length by 2
5(2)
Subtract the length from the perimeter
16-10
Divide the remainder by 2 to find the width
6/2
The width is 3
Length times width equals area
3(5)=15

lozanna [386]

Answer:

9 units

Step-by-step explanation:

Calculate the absolute value of the difference, that is

| - 2 - 7 | = | - 9 | = 9 , or

| 7 - (- 2) | = | 9 | = 9

Erika is working on solving the exponential equation 50x = 17; however, she is not quite sure where to start. Using complete sen

Anastaziya [24]

You have to move everything that is not x, in this case the number 50, to the other side of the equation in order to solve for x. To do this, you would divide both sides by 50. The result would be x=17/50.
