Answer:

f(x) = 100*(1/2)ˣ

Step-by-step explanation:

Exponential function is:

f(x) = a*bˣ

Use two points on the graph to determine the value of a and b:

(0, 100), (1, 50)

Find the values of a and b:

f(0) = a*b⁰ = a = 100
f(1) = a*b¹ = ab = 100b = 50 ⇒ b = 50/100 = 1/2

The function is:

f(x) = 100*(1/2)ˣ

The measures of two angles are given along with the measure of the side 4 points

FrozenT [24]

Answer:

Step-by-step explanation:

Let say for example, the triangle is named ∆ABC, and the two angles given are <A and <B with a given side, c, opposite to the third angle (<C).

Since sum of triangle = 180°, we can find the third angle by saying:

m<C = 180 - (m<A + m<B).

Having found the third angle measure, <C, we can mow apply the Law of Sines to find the length of the other two sides (a and b) that are opposite to <A and <B respectively.
