I'm going to rewrite f(t) to make it a little easier to use the power rule:
Now just take the derivative using the power rule:
Since they ask for f'(a), we need to replace the t's with a's:
Answer:
10m/s
Step-by-step explanation:
The answer should be 10m/s. Hope it helps!
Answer:
Step-by-step explanation:
This is the image of the graph you determine if that's perpendicular.
Perpendicular definition - In elementary geometry, the property of being perpendicular is the relationship between two lines which meet at a right angle. The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.
You will use trig. Try the phrase “SohCahToa” you will use “Soh” meaning Sin is opposite over hypotenuse. So in this instance, it would be sin(x)=8/11. You will need to take the inverse sine to figure out x. So, x= sin^-1(8/11) which turns out to be approximately 46.65°
You should pick none of the above
