Answer:
6sqrt(2) units (exact form)
= 8.49 units (3 sf)
Step-by-step explanation:
sqrt[(-1-5)²+(6-0)²]
sqrt[(-6)² + 6²]
sqrt(36 + 36)
sqrt(72)
= 6sqrt(2) units (exact form)
= 8.49 units (3 sf)
It would take 90 minutes for 9 men to paint a 3600 square foot wall.
Hi
exponnential cannot be negative. So A is out
quadratic function cannot also. So B is out.
C is the only one remaining...
=
1/3 ( because the limit as x approaches 0 of t/sin t = 1 ).
It's important to understand how perfect square trinomials work.
Say we had a factored perfect square trinomial in the form (x - n)²
If we distributed that out we'd have x² + 2nx + n².
Now, take a look at our expression... x² - 10x.
Imagine that 2nx term as 10x...n =5.
In that case, we'd have to add 25 to make our perfect square trinomial
as a rule of thumb: halve the x coefficient, square it, and then add it.
