Daniel is rollerblading at 15 miles per hour

Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15

Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15

15mi per hr
60/12=5
3mi • 5 = 15

Answer:

5.6 x 10^3 (10 to the power of 3)

i.e. 5600 = 5.6 x 10^3 because you have to go back 3 times to get 5.6 *you cannot have a number less than 1 or more than 10*

So the power of 3 is the amount of times you had to move back

Step-by-step explanation:

This is how you write 5600 in standard form!

There will not be any specific name given to that image after translation

<u>Step-by-step explanation:</u>

Whatever may be the transformation, either it may be rotation, reflection or translation, the size or shape of the image will not change no matter what the condition is and hence the name of that image will also not change and remains constant.
Thus we can conclude that the name of the image will always tend to remain constant and not changes.
