MAX POINTS TO BEST ANSWER!

NISA [10]

Note: (f/g)(x) can be written as

f(x)/g(x). This simply means f(x) divided by g(x).

We know what f(x) and g(x) are because that information is given to us in the problem. See it?

Set up the rational function and factor.

(x^2 - 9)/(x^2 -4x + 3)

We now factor the top and bottom.

(x - 3)(x + 3)/(x - 3)(x - 1)

Cancel out common terms.

We now have (x + 3)/(x - 1) as the reduced rational function.

To find the domain, set the bottom to 0 and solve for x.

x - 1 = 0

x = 1

The domain is ALL REAL NUMBERS EXCEPT FOR 1. In the given function, x CANNOT BE 3 because this would create a zero in the denominator.

Answer in interval notation is

(-00, 1) U (1, 3) U (1, 00).

The interval notation reads as follows:

All negative numbers included but not 1 united with the open interval that does not include 1 and 3 united with the interval that excludes 1 but includes all positive numbers greater than 1. I hope this is clear.

Find x and decide if that side (with the x) is an Altitude

irga5000 [103]

Answer:

b = 15
c = 51
c = 100
b = 25.75

Step-by-step explanation:

Using the Pythagoras theorem equation:

$c^{2}=a^{2}+b^{2}$

Where 'c' is the hypotenuse and 'b' and 'a' the sides of the right triangle.

1) Here c = 17, a = 8 and b = ?

Then, using the above equation we can find the side b.

$17^{2}=8^{2}+b^{2}$

$b=\sqrt{225}$

$b=15$

2) Here a = 24, b = 45 and c = ?

$c=\sqrt{24^{2}+45^{2}}$

$c=51$

3) Here a = 28, b = 96 and c = ?

$c=\sqrt{28^{2}+96^{2}}$

$c=100$

4) Here a = 17, b = ? and c = 28

$b=\sqrt{28^{2}-11^{2}}$

$b=25.75$

Just in the 4 case x is an altitude.

I hope it helps you!

Find exact values for sin θ and tan θ if cos θ = -4/9 and tan θ > 0.

julsineya [31]

Answer:

Part 1) $sin(\theta)=-\frac{\sqrt{65}}{9}$

Part 2) $tan(\theta)=\frac{\sqrt{65}}{4}$

Step-by-step explanation:

we have that

The cosine of angle theta is negative and the tangent of angle theta is positive

That means that the sine of angle theta is negative

step 1

Find $sin(\theta)$

we know that

$sin^{2}(\theta) +cos^{2}(\theta)=1$

we have

$cos(\theta)=-\frac{4}{9}$

substitute

$sin^{2}(\theta) +(-\frac{4}{9})^{2}=1$

$sin^{2}(\theta) +\frac{16}{81}=1$

$sin^{2}(\theta)=1-\frac{16}{81}$

$sin^{2}(\theta)=\frac{65}{81}$

square root both sides

$sin(\theta)=\pm\frac{\sqrt{65}}{9}$

Remember that

In this problem the sine of angle theta is negative

$sin(\theta)=-\frac{\sqrt{65}}{9}$

step 2

Find $tan(\theta)$

we know that

$tan(\theta)=\frac{sin(\theta)}{cos(\theta)}$

we have

$sin(\theta)=-\frac{\sqrt{65}}{9}$

$cos(\theta)=-\frac{4}{9}$

substitute the given values

$tan(\theta)=-\frac{\sqrt{65}}{9}:-\frac{4}{9}=\frac{\sqrt{65}}{4}$
