2 ones and 8 hundredths
00.00
the first zero is tens, ones, and after the decimal, to the right is the tenths, hundredths and so on
Hello :
sin<span>θ = 15/17
</span> use pythagorean identity : cos²θ +sin² θ = 1
cos²θ = 1 - sin² θ
cos²θ = 1-(15/17)²
cos²θ = 1- 225/289
cos²θ = 64/289
cos²θ = (8/17)²
cosθ = 8/17 or -8/17
Hello.
is a quadratic function, because it has an 
(x squared, or x times x) term.
Here's what linear functions look like:
A graph of a linear function is a line.
Quadratic functions look like so:
A graph of a quadratic function is a parabola.
Therefore, the given function is a quadratic function.
I hope this helps.
Have a nice day.
a + b = 88 <span>
