stira [4]

Answer:

a. p(x<= 5) = .15 + .4 + .25 = .8

C. .4(4.2) = 1.68

5.4(1-.4) = 3.24

3.24 + 1.68 = 4.92 ,, 4.92 > 4.55 so short is better

Write the expression in terms of sine and cosine, and then simplify so that no quotients appear in the final expression. sec bet

Ede4ka [16]

Answer:

Step-by-step explanation:

The expression given is: sec β - cos β ( i will write "beta" instead of the symbol β)

We know that $sec(x)=\frac{1}{cos(x)}$

Substituting this into the the expression and doing some algebra manipulation, we have:

$sec(beta)-cos(beta)\\=\frac{1}{cos(beta)}-cos(beta)\\=\frac{1-cos^{2}(beta)}{cos(beta)}$

Using the identity $cos^{2}(x)+sin^{2}(x)=1\\$ (also $sin^{2}(x)=1-cos^{2}(x)$ ), we can now write:

$\frac{1-cos^{2}(beta)}{cos(beta)}\\=\frac{sin^2(beta)}{cos(beta)}\\=\frac{sin(beta)*sin(beta)}{cos(beta)}\\=\frac{sin(beta)}{cos(beta)}*sin(beta)$

We know $tan(x)=\frac{sin(x)}{cos(x)}$ , substituting this, we have:

$\frac{sin(beta)}{cos(beta)}*sin(beta)\\=tan(beta)*sin(beta)$

Answer choice E is the right answer.

What is another name for ZY

lianna [129]

In this question , we have a diagram given, and we have to find the another name of ZY .

First we have to see, what ZY represents here.

According to the diagram , ZY represents a line segment since it has two end points Z and Y .

Now we have to check can be name it differently .

And as we see that V is on ZY. So we can also write ZVY for ZY .
