Answer:

1. It increases at 0-15 minutes

2. The rate of change is 3 and I got it by using the formula; \frac{rise}{run} to calculate. So the line went up 15 and right 5 times so it'll be 15/5 = 3

3. It stays constant from 15-35 minutes.

4.The rate of change is 0 because the rate of change for every horizontal line is 0.

5. It decreases from 35-45 minutes

6. The rate of change is -4 and I got it by using the formula; \frac{rise}{run} to calculate. So the line went down -20 and right 5 times so it'll be -20/5 = -4

7. The rate of change is negative because the line is going down which means that the line is negative.

Step-by-step explanation:

1. As you can see the line is going up which means its increasing.

(with steps please) Find the inverse Laplace transform, f(t), of the function: 16/(s-4)^3
Stells [14]

Answer:  The required inverse transform of the given function is

f(t)=8t^2e^{4t}.

Step-by-step explanation:  We are given to find the inverse Laplace transform, f(t), of the following function :

F(s)=\dfrac{16}{(s-4)^3}.

We have the following Laplace formula :

L\{t^ne^{at}\}=\dfrac{n!}{(s-a)^{n+1}}\\\\\\\Rightarrow L^{-1}\{\dfrac{1}{(s-a)^{n+1}}\}=\dfrac{t^ne^{at}}{n!}.

Therefore, we get

f(t)\\\\=L^{-1}\{\dfrac{16}{(s-4)^3}\}\\\\\\=16\times\dfrac{t^{3-1e^{4t}}}{(3-1)!}\\\\\\=\dfrac{16}{2}t^2e^{4t}\\\\\\=8t^2e^{4t}.

Thus, the required inverse transform of the given function is

f(t)=8t^2e^{4t}.

What is the value of a?
Annette [7]

Answer:

<h2>a = 16</h2>

Step-by-step explanation:

Look at the picture.

The formula of an area of a trapezoid is:

A=\dfrac{b_1+b_2}{2}\cdot h

b_1,\ b_2 - bases

h - height

We have:

A=128,\ b_1=a+2,\ b_2=a-2,\ h=8

Substitute:

128=\dfrac{a+2+a-2}{2}\cdot8\\\\128=\dfrac{2a}{2}\cdot8

128=8a          <em>divide both sides by 8</em>

16=a\to a=16

Write the ratio for sin P and cos Q
Gnom [1K]

Answer:

sin p -21/29

cos q 21/29 so here you go °~sohcahtoa~°

Step-by-step explanation:

sin means you find the soh part so you look for the oppisite over hyponuse

and for cos your looking for cah part so you find the adjsent over hypotnuse so the ansers is 21/29

Find the slope of the line passing through the points (-2,5) and (3/2, 2).
sveticcg [70]

Answer:

The answer is

<h2>-  \frac{6}{7}</h2>

Step-by-step explanation:

The slope of the line passing through two points can be found by using the formula

<h3>m =   \frac{y2 - y1}{x2 - x1}</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question

The points are (-2,5) and (3/2, 2)

The slope is

<h3>m =  \frac{2 - 5}{ \frac{3}{2}  + 2}    \\  =   -  \frac{3}{ \frac{7}{2} }  \\  = -  3 \div  \frac{7}{2}  \\  =  - 3 \times  \frac{2}{7}</h3>

We have the final answer as

<h3>-  \frac{6}{7}</h3>

Hope this helps you
