Answer:

Step-by-step explanation:

1. A point on a graph is a maximum if there are no points on the graph that are higher.

A point on a graph is a minimum if there are no points on the graph that are lower.

Sometimes you're interested in a "local" maximum or minimum. In that case, the "no points higher/lower" rule refers to points in the immediate vicinity of the one of interest.

Sometimes you're interested in a maximum or minimum on an interval. In that case, the rule applies to points contained within the interval. (The maximum or minimum may be at the end of the interval.)

__

2. Average rate of change is defined over some interval. That is, you are given the end points of the interval of interest. The average rate of change is the slope of a straight line between those end points. The slope formula applies:

  [tex]m=\dfrac{y_2-y_1}{x_2-x_1} \quad\text{where the end points of the interval are $(x_1,y_1)$ and $(x_2,y_2)$}[/tex]

Answer:

A- 16 songs a day

B- 32 songs in the weekend

Step-by-step explanation:

A- if she songs "jingle bells" 5 times, the sings"silver bells" twice as many times, that would just be like multiplying  5 x 2, which equals 10, then add the 5 times she sings jingle bells, that would be 15. then she sings "silent night" one time which adds on to the other songs to get 16 songs a day

B- the weekend has 2 days in it so you would just multiply 16 x 2 which gives you 32

Answer:

The band must sell at least 113 tickets to make a net profit of at least $ 1,925.

Step-by-step explanation:

While the band charges $ 25 for each entrance ticket to their performances, and the venue charges them $ 900 for the use of the place, the number of tickets that must be sold for the band to obtain a profit of at least $ 1,925 arises from the following calculation:

1,925 + 900 = Costs plus profit

2,825 / 25 = Number of tickets needed to cover costs and profit

113 = Number of tickets needed to cover costs and profit.

Therefore, the band must sell at least 113 tickets to make a net profit of at least $ 1,925.

Answer:

2 : 1

Step-by-step explanation:

Recipe :

Sugar = 2 cups

Flour = 3 cups

Butter = 1 cup

Chocolate chips = 1/2 cup

ratio of flour and butter to sugar?

Total cups of flour plus butter = (3 + 1) = 4 cups

Cups of sugar = 2 cups

ratio of flour and butter to sugar :

4 cups : 2 cups

= 2 : 1

Answer:

The correct unit price is $1.12 per pair. The error comes from dividing $67.20 by only 5 pairs (instead of 60 pairs).

Step-by-step explanation:

The contractor should have calculated the unit price as $67.20 divided by 60 pairs. Five dozen pairs is 5x12=60. This results in $67.20/60=$1.12 per pair. The error comes from dividing $67.20 by only 5 pairs (instead of 60 pairs).

Answer:

115.2

Step-by-step explanation:

Answer: 115.2

Step-by-step explanation:

What is 24% of 480?

Y is 24% of 480

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 24% * 480

Converting percent to decimal:

p = 24%/100 = 0.24

Y = 0.24 * 480

Y = 115.2

Step-by-step explanation:

The slope of the line is -4/7.

Given:

The measurement of the angles of a triangle are 3b,2b,and 4b.

To find:

The smallest angle.

Solution:

According to the angle sum property, the sum of all angles of a triangle is 180 degrees.

[tex]3b+2b+4b=180^{\circ}[/tex]           [Angle sum property]

[tex]9b=180^{\circ}[/tex]

Divide both sides by 9.

[tex]b=20^{\circ}[/tex]

Now,

[tex]3b=3(20^{\circ})=60^{\circ}[/tex]

[tex]2b=2(20^{\circ})=40^{\circ}[/tex]

[tex]3b=4(20^{\circ})=80^{\circ}[/tex]

Therefore, the smallest angle is 40 degrees.

Answer:

[tex]y = 50x[/tex]

Step-by-step explanation:

Let's start off by trying to find the slope/gradient (commonly denoted as [tex]m[/tex]) of this function

[tex]m = \frac{\Delta y}{\Delta x}[/tex]

This means we divide the change in y over the change in x

Let's pick, for example, x = 3 (who's corresponding y is 150) and x = 4 (who's corresponding y is 200)

[tex]m = \frac{200 - 150}{4 - 3}\\\\m = 50[/tex]

Now we have this:

[tex]y = 50x+b[/tex]

Let's plug in a random value of x and y from this function in order to find b. I'll pick x = 2:

[tex]100 = 50\cdot 2 + b\\100 = 100 + b\\b = 0[/tex]

Since b is 0, we don't have to write it on our equation, meaning that our final equation is just

[tex]y = 50x[/tex]

To verify this, let's say we didn't know the value of y when x is equal to 4 and all we had was that equation:

[tex]y = 50\cdot 4\\y = 200[/tex]

Just like it is on the graph :)

Good luck!

Answer:

C

Step-by-step explanation:

The general form of a polynomial expression is

[tex]a_{n}[/tex][tex]x^{n}[/tex] + [tex]a_{n-1}[/tex][tex]x^{n-1}[/tex] + [tex]a_{n-2}[/tex][tex]x^{n-2}[/tex] + ............ + a₁[tex]x^{1}[/tex] + a₀

For the given polynomial the [tex]x^{n}[/tex] term is - [tex]x^{13}[/tex] , that is n = 13 , thus

n - 7 = 6 , that is the [tex]x^{6}[/tex] term

with [tex]a_{n-7}[/tex] being its coefficient

Since there is no [tex]x^{6}[/tex] term, then its coefficient is zero, that is

[tex]a_{n-7}[/tex] = 0 → C

Answer:

4 years old

Step-by-step explanation:

His sister is x years old.

Gary is 1 year less than 3 times her age, so his age is

3x - 1

His age is 11, so we can write an equation.

3x - 1 = 11

Add 1 to both sides.

3x = 12

Divide both sides by 3.

x = 4

Answer:

The height of water in the container is 5 cm

Step-by-step explanation:

Here, we want to calculate the height of the water in the container

Mathematically, the volume is :

50 * 30 * h = 1500h cm^3

Also, 7.5 L = 7500 cm^3 = 7.5 L

Let the height be h

1500h = 7500

h = 7500/1500

h = 5 cm

Let's solve your equation step-by-step.

4x−2=2x

Step 1: Subtract 2x from both sides.

4x−2−2x=2x−2x

2x−2=0

Step 2: Add 2 to both sides.

2x−2+2=0+2

2x=2

Step 3: Divide both sides by 2.
