Answer:

Q4) 256 roses

Q5) 40 hamburgers

Q6) 60 professors and 168 lecturers

Q7) 20 percussionist on the sideline

Step-by-step explanation:

Q4) First to set up a proportion you simply have to write a letter to represent the missing number. In this case we'll be using x. So it'll look something like these:

I) 160:5 = x:8 (using colon) or

II) 160/5 = x/8 (as two equal fractions)

You can use one of the two above.

I used the fractions here to solve the question.

After setting up the proportion, your going to cross multiply to get the value of x so its going to look like this:

160×8 = 5×x

1280 = 5x

5x = 1280

Now you have to divide on both sides to isolate x.

5x÷5 = 1280÷5

x = 256

Therefore your answer is 256 roses.

Q5) Use the same method in Q4.

Q6) This is where the proportion using colon comes in. It should look like this 5:14. 5 representing the professors and 14 the lecturers. Now it said that the total number of faculty members is 228.

First thing your going to do is add the proportion together. So basically 5+14=19.

After acquiring this your going to use the sum to divide the total number of faculty members which is 228. So 228÷19=12.

And finally you now have to multiply both sides of the proportion by 12. Therefore 5×12:14×12

60:168

To make sure the answer is right add the proportions of the working above which will give you the total number of faculty members. 60+168=228.

Your final answer: There are 60 professors and 168 lecturers.

Q7) Use the same method done in Q6.

I gave the answers to questions 5 and 7 because I wanted to give you the opportunity to try out the working outs yourself for a better understanding on your part and see if you can get the same answers as me. Anyway hope this helped.

The measure of m∠14 is 110 degrees and the angle relationship is a supplementary angles

Let us assume that angle m∠10 and m∠14 are supplementary, this means that the sum of both angles will be 180 degrees.

Since the angles are supplementary, hence the required expression will be:

m∠10 + m∠14 = 180

Given that m∠10 = 70 degrees

70 + m∠14 = 180

m∠14 = 180 - 70

m∠14 = 110 degrees

Hence the measure of m∠14 is 110 degrees and the angle relationship is a supplementary angle.

Answer:

True

Step-by-step explanation:

The Factor theorem states that  for any polynomial f(x) if f(c)=0 then x-c is a factor of the polynomial f(x).

If any polynomial f(x) is divided by x-a and remainder is 0 that means f(a)= 0 .In other words we can say x-a is a factor of the polynomial f(x).So the statement :If a polynomial is divided by (x-a) and the remainder equals zero then (x -a) is a factor of the polynomial is True.

Answer:

B. 7.5%

Step-by-step explanation:

First, we need the Simple Interest (S.I)

Total = Principal + Simple Interest

T = P + S.I

6500 = 5000 + S.I

[make S.I the subject of the formula]

S.I = 6500 - 5000

S.I = 1500

Simple Interest = (Principal × Rate × Time) / 100

S.I = (P × R × T) / 100

1500 = (5000 × R × 4) / 100

1500 = 20000R / 100

1500 = 200R

[divide both sides of the equation by 200]

1500 / 200 = 200R / 200

R = 1500 / 200

R = 7.5

The annual interest rate is 7.5%

The quadratic equation with the given conditions is:

[tex]f(x) = \frac{3}{16}(x^2 + 2x - 24)[/tex]

The standard form of a quadratic equation with roots [tex](x_1,0)[/tex] and [tex](x_2,0)[/tex] is given by:

[tex]f(x) = a(x - x_1)(x - x_2)[/tex]

In which a is the leading coefficient.

In this problem, the roots are [tex]x_1 = -6, x_2 = 4[/tex], thus:

[tex]f(x) = a(x - (-6))(x - 4)[/tex]

[tex]f(x) = a(x + 6)(x - 4)[/tex]

[tex]f(x) = a(x^2 + 2x - 24)[/tex]

It passes through point (2,-3), which means that when [tex]x = 2, f(x) = -3[/tex], and this is used to find a.

[tex]a(2^2 + (2)(2) - 24) = -3[/tex]

[tex]-16a = -3[/tex]

[tex]a = \frac{3}{16}[/tex]

Thus, the equation is:

[tex]f(x) = \frac{3}{16}(x^2 + 2x - 24)[/tex]

The statements that are true about the functions are:

The leading coefficient is positive.

It has two relative maximums

It has four linear factors.

One of the zeroes is x = 2.

Polynomial is an equation written as the sum of terms of the form kx^n.

where k and n are positive integers.

We have,

From the graph,

The graph passes through the following points on the graph.

x = -4

x = -2

x = 2

x = 6

This means the polynomial function is:

P(x) = (x + 4)(x + 2)(x - 2)(x - 6)

If we simplify the polynomial we get,

P(x) = (x² + 2x + 4x + 8) (x² + 6x - 2x + 12)

P(x) = [tex]x^{4}[/tex] + 6x³ - 2x³ + 12x² + 2x³ + 12x² - 4x² + 24x + 4x³ + 24x² - 8x² + 48x + 8x² + 48x - 16x + 96

P(x) =[tex]x^{4}[/tex] + 10x³ + 44x² + 104x + 96

The leading coefficient is positive 1 so it is positive.

The constant term is a positive number (96).

The relative maximum is a point on the graph where the function changes from increasing to decreasing.

So,

From the graph, there is only one point.

So only one relative maximum.

The relative minimum is a point on the graph where the function changes from decreasing to increasing.

So,

From the graph, there are two relative maximums.

The function has four linear factors

(x + 4), (x + 2), (x - 2), and (x - 6).

x = -4, x = -2, x = 2, and x = 6

Thus,

The statements that are true about the functions are:

The leading coefficient is positive.

It has two relative maximums

It has four linear factors.

One of the zeroes is x = 2.
