what is te discontinuity of the function f(x) = the quantity of x squared plus 6x plus 8 all over x plus 4?
seropon [69]

Answer:

A hole at x=-4.

Step-by-step explanation:

This is a fraction so we have to worry about division by zero.

The only time we will be dividing by 0 is when x+4 is 0.

Solving the equation

x+4=0 for x:

Subtract 4 on both sides:

x=-4

So there is either a vertical asymptote or a hole at x=-4.

These are the kinds of discontinuities we can have for a rational function.

If there is a hole at x=-4, then x=-4 will make the top zero and can be cancelled out after simplification.

If is is a vertical asymptote, x=-4 will make the top NOT zero.

Let's see what -4 for x in x^2+6x+8 gives us:

(-4)^2+6(-4)+8

16+-24+8

-8+8

0

Top and bottom are 0 when x=-4.

Let's see what happens after simplication.

We are going to factor a^2+bx+c if factorable by finding two numbers that multiply to be c and add up to be b.

So what 2 numbers together multiply to be 8 and add up to be 6.

I hoped you said 4 and 2 because (4)(2)=8 where 4+2=6.

\frac{x^2+6x+8}{x+4}=\frac{(x+4)(x+2)}{x+4}=x+2

We we able to cancel out that factor that was giving us x=-4 is a zero.  

Therefore there is a hole at x=-4.

Safe or not, he made it up the tower, since he is, after all, a warrior. The ransom note
Alona [7]

The width of the river = 60m and so Zachary will be able to swim the river without getting tired.

<h3>What is Proportion ?</h3>

When two ratios are equal , the ratio are said to be in proportion.

As given in the question ,

the width of the river has to be determined

Looking at the figure , the triangle formed at the side of the river is a right triangle the hypotenuse will be determined from the Pythagoras theorem

20² +24² = y²

y = 21.2 m

As the corresponding sides are proportional

31.2 : z = 20:50

z = 78.1

The value of the width of the river will be determined by the Pythagoras Theorem

78.1² = 50² + x²

x = 60m

the width of the river = 60m

Therefore Zachary will be able to swim the river without getting tired.

Use the following diagram for questions 4 - 6.
jonny [76]

Answer:

1. C

2. B

3. B

Step-by-step explanation:

Vertical angles are the angles opposite each other when two lines cross, thus angles with measures (x+77)° and 126° are vertical angles.

Vertical angles are congruent.

Hence,

x+77=126\\ \\x=126-77\\ \\x=49^{\circ}
