KE=1/2(m)(v)^2
KE=1/2(80)(1.5)^2
KE=90 J
Answer:
See below.
Step-by-step explanation:
Squaring a number means to multiply the number by itself.
For example, 3^2 means 3 * 3.
8^2 means 8 * 8.
(-6)^2 means (-6) * (-6).
In each case above, you see that the number that is squared is multiplied by itself.
In this case, (-4.5)^2, squaring the number -4.5, means multiply the number -4.5 by the number -4.5
(-4.5)^2 = (-4.5) * (-4.5)
Now we need to actually multiply -4.5 by -4.5
When you multiply a negative number by a negative number, the result is positive, so the product of -4.5 and -4.5 is a positive number. To find that number, you multiply 4.5 by 4.5
4.5 * 4.5 = 20.25
Therefore, (-4.5)^2 = 20.25
The Tampa Tribune expecting to add 700 new pictures per year to their database in 2041
<h3>The linear equation of the graph</h3>
The equation of the line of best fit is given as:
When the number of pictures added is 700, we have:
y = 700
Substitute 700 for y in
Subtract 367 from both sides of the equation
Rewrite the above equation as:
Divide both sides by 8
Remove decimal (do not approximate)
This means that:
Hence, the Tampa Tribune expecting to add 700 new pictures per year to their database in 2041
