Put the first coordinate to the equation of a function.

f(x)=3^x\\\\\left(-2,\ \dfrac{1}{9}\right)\to f(-2)=3^{-2}=\dfrac{1}{3^2}=\dfrac{1}{9}\qquad\text{On the graph}\\\\\left(-1,\ -\dfrac{1}{3}\right)\to f(-1)=3^{-1}=\dfrac{1}{3}\qquad\text{Not on the graph}\\\\(0,\ 3)\to f(0)=3^0=1\qquad\text{Not on the graph}\\\\(1,\ 3)\to f(1)=3^1=3\qquad\text{On the graph}\\\\(2,\ 6)\to f(2)=3^2=9\qquad\text{Not on the graph}\\\\(3,\ 27)\to f(3)=3^3=27\qquad\text{On the graph}

The leg of a right triangle is 3 units and the hypotenuse is 4 units. What is the length, in units, of the other leg of the tria
Dmitry [639]

Answer:

square root of 7

Step-by-step explanation:

Each right angle triangle has 3 sides known as the opposite, adjacent and hypotenuse sides. The relationship between these 3 sides is as defined by pythagoras theorem which states that

a² + b² = c²

where a and b are the lengths of the opposite and adjacent sides (in no particular order) and c is the length of the hypotenuse side.

Given that the leg of a right triangle is 3 units and the hypotenuse is 4 units, it means that

a² + 3² = 4

where a is the length in units, of the other leg of the triangle

a² = 4² - 3

a² = 16 - 9

= 7

a = √7
