Answer:

She is 13.45 meters from her starting point.

Step-by-step explanation:

Use Pythagorean Theorem (a^2+b^2=c^2) so 9^2+10^2=c^2. Solve it algebraically and you get c= 13.45 (rounded to nearest hundredth).

Find the derivative of f(x) = 8x^2 + 11x at x = 7.

sleet_krkn [62]

Thank you for posting your question here at brainly. Feel free to ask more questions.

f′(x)=2∗(8x(2−1))+1∗11x(1−1)

which is

f′(x)=16x+11

then let x = 7 gives us

f′(7)=123

Hope my answer would be a great help for you.
