S(x)=3x²
t(x)=4x
(t*s)(-2)=(3x² * 4x)(-2)=(12x³)(-2)=-24x³

Answer: (t*s)(-2)=-24x³

The dwarf seahorse hippocampus zosterae swims at a rate of 52.68 feet per hour.convert this speed to ines per minute

DaniilM [7]

<h3>52.68 feet per hour = 10.536 inches per minutes</h3>

<h3>Further explanation</h3>

Acceleration is rate of change of velocity.

$\large {\boxed {a = \frac{v - u}{t} } }$

$\large {\boxed {d = \frac{v + u}{2}~t } }$

<em>a = acceleration ( m/s² )</em>

<em>v = final velocity ( m/s )</em>

<em>u = initial velocity ( m/s )</em>

<em>t = time taken ( s )</em>

<em>d = distance ( m )</em>

Let us now tackle the problem !

$1 ~ foot = 30.48 ~ cm$

$1 ~ inch = 2.54 ~ cm$

$1 ~ foot = 12 ~ inches$

$\boxed {52.68 ~ feet = 52.68 \times 12 ~ inches = 632.16 ~ inches}$

$1 ~ day = 24 ~ hours$

$\boxed {1 ~ hour = 60 ~ minutes}$

If the dwarf seahorse hippocampus zosterae swims at a rate of 52.68 feet per hour , then :

$52.68 ~ feet/h = \frac{52.68 ~ feet}{1 ~ hour}$

$52.68 ~ feet/h = \frac{52.68 \times 12 ~ inches}{60 ~ minutes}$

$52.68 ~ feet/h = \frac{632.16 ~ inches}{60 ~ minutes}$

$\large {\boxed {52.68 ~ feet/h = 10.536 ~ inches/min} }$

When creating lines of best fit, do you believe that estimation by inspection of the equation is best or do you think it should

Alex73 [517]

Answer:

Estimation by inspection is better than trying to determine the line of best fit exactly

i) For a scatter plot : The use of estimation by inspection

ii) For a straight line graph : The exact determination method

Step-by-step explanation:

To create lines of best fit the estimation by inspection is better than trying to determine the line of best fit exactly .

This is because line of best fit only shows the trend of the data and in most cases it doesn't have to start from origin.

Scenarios :

i) For a scatter plot : The use of estimation by inspection

ii) For a straight line graph : The exact determination method

Find slopes , ill mark brainlist

zepelin [54]

Answer:

$\frac{3}{2}$ $or$ $1\frac{1}{2}$

Step-by-step explanation:

We are given a graph and asked to find the slope.

So we can see two coordinate points, one on (0, 3) and (2, 0).

When trying to find slope, we use the method rise over run, which basically means y over x as a fraction, in which you then divide.

So count how many times it'll take for x to get to y, base it off the picture below

Since we see our numbers to be divided are 3 over 2, do the division and you get 1 1/2.

Would this be negative though? No, since the graph is in an increase, not a decrease.
