Answer:
600 m
Step-by-step explanation:
You know that she walks 1 meter in 1 second, but they're asking about minutes. Since 60 seconds are in 1 minute, it means she was 60 meters in 1 minute. Then multiply that by 10 (10 minutes).
She walked 600 meters, in 10 minutes.
I hope this helped!
Answer:
no
Step-by-step explanation:
Start by adding together the shortest two sides, 7 and 8.7 inches. Result: 15.7 inches. Because this sum is greater than the longest side, 15.4 inches, it's possible to construct a triangle, whose largest angle will be close to 180 degrees.
Answer:
f(-7)=0.
f(2)=-9/5.
f(3) doesn't exist because 3 isn't in the domain of the function.
Step-by-step explanation:
is the given function.
We are asked to find:


.
f(-7) means to replace x in the expression called f with -7:
Evaluate
at 



So f(-7)=0.
f(2) means to replace x in the expression called f with 2:
Evaluate
at 



So f(2)=-9/5
f(3) means to replace x in the expression called f with 3:
Evaluate
at 


Division by 0 is not allowed so 3 is not in the domain of our function.
