Sketch a graph of the greatest integer function y=[[cosx]]

1 answer:

6 0

Let me help you in this way:
the range will have only three values.... -1, 0, and 1...
for: 0≤x<π2, y=0
x = π/2, y = 1
π/2<x<π, y=0
Then what you need to do is to figure out the values for π<x<2π

How do you Rewrite f(x) = −(x + 3)2 − 1 from vertex form to standard form?

wel

Expand it

-(x+3)^2-1
-(x+3)(x+3)-1
-1(x^2+3x+3x+9)-1
-1(x^2+6x+9)-1
-x^2-9x-9-1
-x^2-9x-10

f(x)=-x^2-9x-10

Evaluate the expression. P(9, 3) · P(5, 4)

boyakko [2]

Answer:

$P(9,3) *P(5,4)$

And if we use the permutation formula given by:

$nPx = \frac{n!}{(n-x)!}$

And replacing we got:

$\frac{9!}{6!} \frac{5!}{4!}= 504*5 = 2520$

Step-by-step explanation:

For this problem we want to find the following expressionÑ
