Answer:

3.92*10^3mm

Step-by-step explanation:

In the diagram it gives you 7900mm. There is a figure which was given underneath written 900mm. use 7900 to subtract 900 you will get 7000. Then you can use the Pythagoras theorem to solve it, with a= height, b=5800mm and c=7000mm where, a^2+b^2=c^2.

Answer:

3919 mm

Step-by-step explanation:

Length of hypotenuse = 7900 - 900 = 7000 mm

Base = 5800 mm

Let the height of the triangle be h mm

Therefore, by Pythagoras theorem:

h = \sqrt{7000^2 - 5800^2}

h = \sqrt{49000000- 33,640,000}

h = \sqrt{15,360,000}

h = 3,919.18359\: mm

h = 3,919\: mm

5/6 plus - 1/6 yes that is a negative just so you know it isn’t there on accident lol
zhannawk [14.2K]

5/6 + (-1/6)

is the same as

5/6 - 1/6

  • Subtract the numerators and keep the same denominators.

5/6 - 1/6 = 4/6

  • Simplify 4/6 by dividing it by 2/2.

4/6 ÷ 2/2 = 2/3

  • 4/6 = 2/3
<h3>Your answer is 2/3.</h3>

Question is in the image. I need help with #19
Naddika [18.5K]

EXPLANATION

Replacing the given functions into the following:

\frac{f(x+h)-f(x)}{h}\frac{x^2-1+h-(x^2-1)}{h}

Removing the parentheses and simplifying:

\frac{x^2-1+h-x^2+1}{h}

Simplifying like terms:

\frac{h}{h}=1

Hence,

\frac{f(x+h)-f(x)}{h}=1
