Answer:

(Please vote me Brainliest if this helped!)

Step-by-step explanation:

The angle shown is a right angle. Right angles have a total of 90°.

Therefore, I simply multiplied each answer by 4 because 4(x) = (answer).

A. 4 (14) = 56 + 42 = 98° ≠ 90° INCORRECT

C. 4 (10) = 40 + 42 = 82° ≠ 90° INCORRECT

B. 4 (16) = 64 + 42 = 106° ≠ 90° INCORRECT

D. 4 (12) = 48 + 42 = 90° = 90° CORRECT

An easier way to solve this problem is by simply just subtracting and dividing:

90 - 42 = 48

48 ÷ 4 = 12

Given (x)=-x²+2x,determine<br> F'(x) using first principle

mote1985 [20]

Hello,
which principle?

f(x)=-x²+2x
==>f'(x)= -2x+2

You mean maybe this

$\lim_{h \to 0} \frac{f(x+h)-f(x) } {h}$

f(x+h)=-(x+h)²+2(x+h)= -(x²+2hx+h²)+2x+2h
f(x)=-x²+2x

$\lim_{h \to 0} \frac{f(x+h)-f(x) } {h}=\lim_{h \to 0}\frac{-2hx-h^2+2h}{h}=\lim_{h \to 0}\frac{-2x-h+2}{1}=-2x+2$
