Step 1: evaluate f(x+h) and f(x)
We have


And, of course,

Step 2: evaluate f(x+h)-f(x)

Step 3: evaluate (f(x+h)-f(x))/h

Step 4: evaluate the limit of step 3 as h->0

So, we have

Yes it's a right triangle. Using the Pythagoran
10^2 + 24^2 = 26^2
Thus it's a right triangle
2.5 X 10^-3 is the scientific notation for 0.0025
Answer: See explanation
Step-by-step explanation:
You didn't give the options relating to the question.
To solve this first, you need to know that we have to note that (+) × (-) = (-). Therefore, 1.25+(-0.75) will be thesame as writing 1.25 - 0.75. This will then be:
= 1.25 - 0.75
= 0.50
Answer:
x = 20
Step-by-step explanation:
This isn't too difficult once you understand it.
The bottom left angle of the left triangle (on the other side of 110), that angle is congruent to the 70 degrees angle. that angle is 70 degrees. y = 90 degrees, 90 + 70 = 160
180 - 160 = 20
