The figure is a right triangle so we can use the Pythagorean theorem to find the third side AKA the hypotenuse.
Pythagorean theorem = a² + b² = c² where A and B are the legs of the triangle and C is the hypotenuse.
39² + 80² = c²
169 + 6400 = c²
6569 = c²
Square root both sides to cancel out the squared variable.
√6569 = √(c²)
√6569 = c
The third side, the hypotenuse, is √6569 units long.
Answer:
5/1

Cause I say so. Rise/run is rate of change.
Answer:
Step-by-step explanation:
We begin with m(x) = 3^x.
Then -m(x + 1) = -3^(x + 1). Here we've inserted the ' - ' sign and replaced x with (x + 1).
direct proportion y=kx , k is constant and k does not equal to 0.
17.5=k(21)
k=5/6
when x =39
y=5/6 ×39
y=32.5
