How do you find the rate of change of a function?​
Kobotan [32]

Answer:

We calculate the slop of a line.

How to find the slope:

Pick any two points on a graph

The formula of slope is \frac{Y2-Y1}{X2-X1}

For example we have two points that contains the coordinates (5,2) (7,4)

Inserting them to the formula would result in:

\frac{4-2}{7-5}

=\frac{2}{2}

Our rate of change is rise 2, run 2.

What is the answer to this??
Helga [31]

Since the triangle is equilateral, all its angles are equal to 60°

AO is the bisector⇒∠OAD = 30°

AO AO is the hypotenuse, ∠OAD = 30°⇒

OD=10:2=5ft

By the Pythagorean theorem

10^2=AD^2+5^2\\AD=\sqrt{100-25} \\AD=\sqrt{75}

AC=AD+DC=2\sqrt{75}=10\sqrt{3}

S=\frac{a^2\sqrt{3} }{4}

S=\frac{(10\sqrt{3})^2\sqrt{3}  }{4} =\frac{300\sqrt{3} }{4} =75\sqrt{3} ft^2

Answer: A) S=75\sqrt{3}ft²
