Which function represents the graph

A

Step-by-step explanation:

Exponential graphs are a curve that approaches the x-axis unless a value has been added or subtracted to it. In this graph, the curve approaches the x-axis. This means 100 has NOT been added or subtracted. Instead it is the initial value meaning it has been multiplied to it so when x= 0 y= 100. This occurs because any base to a zero exponent is 1. So 100*1 = 100.

The curve is also decreasing meaning the base is less than 1. So the ase must be 2/5 or 3/5. Thus only A or D are options.

To determine, plug (1,60) into the equations and see if they work.

When x = 1, then y = 100 * 3/5  =300/5 = 60.

So A is the solution.

3 ft

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3
