Answer:

Yes.

Step-by-step explanation:

A quadrilateral is any polygon with four sides. A rectangle, by definition, is a polygon with four sides and four right angles. Thus, every rectangle is a quadrilateral.

Answer: B

Step-by-step explanation:

In order to get the best representative sample, you should choose the widest range of students, which is from a random sample of all students.

(A) Choosing from only the 6th graders, eliminates the choices the other grade-level students would choose.

(C) Choosing only from students who participate in after-school activities, eliminates the choices the other students would choose.

(D) Chhosing only from students not participating in the fundraiser is silly since you want to know what the students participating in the fundraiser would choose.

The only possible option is B - students from all grades, regardless of whether or not they participate in after-school activities.

Answer:

Minimum is a 4th Degree

Positive; Even

$x=-4, -1\text{ Odd Multiplicity}\\x=3\text{ Even Multiplicity}$

Step-by-step explanation:

Part 1)

The minimum degree of our function will be 4.

Looking at the graph, we know that the graph crosses the x-axis at -4 and -1. Since it crosses through the x-axis at these two points, these two factors must have an odd multiplicity.

So, it can be anything 1, 3, 5, 7, etc.

However, we will choose the lowest one, 1.

Next, we know that the graph bounces off at 3.

So, it must have an even multiplicity. In other words, 2, 4, 6, 8, etc.

We choose the lowest one, 2.

Therefore, the minimum degree of our function will be 1+1+2 or 4.

Part 2)

The degree of our polynomial is (and will always be) even. Therefore, both ends of the graph will go in the same direction.

Recall the simplest even polynomial, the parent quadratic function. When the leading coefficient is positive, both of the ends go straight up.

This applies to all polynomials with even degrees.

Therefore, since the arms of the graph is going straight up towards positive infinity, the leading coefficient of our graph must be positive.

Part 3)

This is similar to Part 1.

We can see that the graph touches the x-axis at -4, -3, and 1. So, the zeros of the function is: $x=-4, -1, 3$

We know that it passes through $x=-4 \text{ and } x=-1$ . So, these two factors must have an odd multiplicity.

However, since the graph bounces off $x=3$ , this factor must have an even multiplicity.

And we're done!

% of 6,000 = 4,500 Please help

babymother [125]

Answer:

450

Step-by-step explanation:

Solution for What is 75 percent of 600:

75 percent * 600 =

(75:100)* 600 =

(75* 600):100 =

45000:100 = 450

Now we have: 75 percent of 600 = 450

Question: What is 75 percent of 600?

Percentage solution with steps:

Step 1: Our output value is 600.

Step 2: We represent the unknown value with $x$x.

Step 3: From step 1 above,$600=100\%$600=100%.

Step 4: Similarly, $x=75\%$x=75%.

Step 5: This results in a pair of simple equations:

$600=100\%(1)$600=100%(1).

$x=75\%(2)$x=75%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

600

100%

75%

Step 7: Again, the reciprocal of both sides gives

600=

100

Therefore, $75\%$75% of $600$600 is $450$
