Answer:
a = 8, b =
Step-by-step explanation:
Given the exponential function
f(x) = a
To find a and b use the given coordinate points on the graph
Using (0, 8 ), then
8 = a [
= 1 ] , then
a = 8
f(x) = 8
Using (2, 18 ) , then
18 = 8b² ( divide both sides by 8 )
= b² , that is
b² = ( take the square root of both sides )
b = =
Thus
f(x) = 8
Answer:
The other side = units
Step-by-step explanation:
A right triangle has a side of length units and;
the hypotenuse is
According to Pythagorean theorem,
a² + b² = c² , where a and b are the two legs of a triangle and c is the hypotenuse.
Lets say a² = and c² = (
b² = c² - a²
b² = -
=
So b = =
units.
So the other side = units.
