PLEASE HELP ITS TIMED I DONT NEED BIG EXPLAINATION

Jane uses red and blue square tiles to make a design. Her design includes 4 squares that are each x tiles long. She has exactly 16 red tiles and uses them all in her design. The number of blue tiles in her design is modeled by the function b(x)=4x2−16

.


How can b(x)

be written to show how long Jane's squares are when her design includes zero blue tiles?


A

b(x)=4(x2−3.5)−2

B

b(x)=4(x2−4)

C

b(x)=4(x+2)(x−2)

D

b(x)=4(x2−2)−8

Answers

Answer 1

Answer:

(C ) b(x)=4(x+2)(x−2)

Step-by-step explanation:

We are given

The number of blue tiles in her design is modeled by the function b(x)=[tex]4x^2-16[/tex]

if the no of blue tiles used is zero then

b(x) =[tex]4x^2-16[/tex] = 0

       [tex]x^2 = 16/4[/tex] = 4

      x = +2 and -2

this is the condition for blue tiles

Modelling

b(x) = 4(x+2)(x-2)

This means when the blue tiles used are zero, then we use 2 red tile on each of the two square of 4 square. so the length will be 4 tiles long and its a square so 4x4 = 16 red tiles.

Which of the following best describes the graph above?

A. Function only
B. Relation only
C. Both relation and function
D. Neither relation nor a function

Answers

Answer: C

Step-by-step explanation:

We know that a relation is any set of ordered pairs, but a function is when there is only one y value for x value.

So, basically, if a graph is a function, it is a relation as well.

Let’s check if this is a function.

We can use the vertical line test- if we draw a vertical line through any point on the graph and it only intersects one point, it is a function

In our case, it passes the vertical line test.

Therefore, it is both a function and a relation, which corresponds to letter C.

Hope this helps! :)

You are rolling one die. Let event A = rolling a six and let event B = rolling a number less than
four. What is the probability of A or B?

Answers

Answer:

2/3

Step-by-step explanation:

A = rolling a six

B = rolling a number less than 4

Probability of A or B

P(A) or P(B) = P(A) + P(B) - P(AnB)

Probability = (number of required outcome / Total possible outcomes)

P(A) = 1 / 6

P(B) :

Required outcomes = (3, 2, 1) = 3

P(B) = 3/6 = 1/2

P(AnB) = A={6} ; B = {1,2,3} ; AnB = {}

P(AnB) = 0

Hence,

P(A) or P(B) = 1/6 + 1/2 - 0

= (1 + 3) / 6

= 4/ 6

= 2/3

Overall, divorce rates have declined in the last 20 years, but among middle-aged couples, the rates are rising. Do an internet search to find what current statistics are available for different groups of individuals, then describe three factors that contribute to contemporary rises in middle-aged divorce rates.

Answers

Answer:

The current divorce rate is about 7% based on the survey.

Step-by-step explanation:

The divorces occur when two person fails to accept each other as a life partner. In the country the divorce rate is about 7% of which mostly couples are at the age of 20 - 25. The people of age 30 plus are less likely to get divorced as they have matured mind sets which accepts each other differences and tries to adjust the situation.

Divorce describes a form of marital separation which is usually undertaken by a court. It occurs when one or both partners decide to quit being married.

The middle age divorce rate continues to rise, as it is being reported in various channels. Currently the middle age divorce rate stands at about 17% per 1000 married person.

The causes of rising divorce rates among middle - aged may include :

Rising cases of infidelity as spouses continue to find it difficult to be committed in marrige. Sacrifices which helps foster lasting partnership can no longer be undertaken.

Also, the need to be independent as taken over at this time, as partners begin to see marriage as a bond age which prevents or curtails them from what they would love to indulge in.

Lastly, some now see divorce as norm due to the social influence it has transmitted across to various individuals. Now, so many choose to divorce at any minor challenge marriage brings.

Answer:

Step-by-step explanation:

Angle Measurement Units

To convert from different units for angle measurements, we have to recall that:

180 degrees = π radians

If we are given the angle in degrees, multiply by π/180 to convert it to radians.

If the angle is given in radians, multiply by 180/π to convert to degrees.

We are given the angle:

[tex]\displaystyle x=\frac{15}{16}\pi[/tex]

Multiplying by 180/π:

[tex]\displaystyle x=\frac{15}{16}\pi\cdot \frac{180}{\pi}[/tex]

Simplifying:

[tex]\displaystyle x=\frac{15*180}{16}[/tex]

A system of equations is graphed on the grid.

Which system of equations does the graph represent?

Answers

Answer:

y = x + 4

y = -2x - 4

Step-by-step explanation:

Since equation of the line having slope 'm' and y-intercept 'b' is given by,

y = mx + b

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of line passing through (1, 5) and (-1, 3),

m = [tex]\frac{5-3}{1+1}[/tex] = 1

y-intercept 'b' = 4

Therefore, equation of the line is,

y = 1.x + 4

y = x + 4

Now slope of another line passing through (-4, 4) and (-1, -2) will be,

m = [tex]\frac{4+2}{-4+1}[/tex]

m = -2

y-intercept 'b' of this line = -4

Equation of the other line,

y = (-2)x - 4

y = -2x - 4

Therefore, system of equations is,

y = x + 4

y = -2x - 4

The system of equations is given by: y = x + 4 and y = -2x - 4

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the rate of change and b is the y intercept.

The first line passes through point (-1, 3) and (1, 5) hence:

[tex]y- y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-3=\frac{5-3}{1-(-1)} (x-(-1))\\\\y=x+4[/tex]

The second line passes through point (-4, 4) and (-1, -2) hence:

[tex]y- y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-4=\frac{-2-4}{-1-(-4)} (x-(-4))\\\\y=-2x-4[/tex]

The system of equations is given by: y = x + 4 and y = -2x - 4

Find the Unit Rate: If 12 50.7 FI. Oz. bottles cost $84 how much does one bottle cost? Find the init Rate.​

Answers

Your statement is a little ambiguous due to type mistake, so I am assuming you meant to say:

'if 12 fl. oz. bottles cost $84 how much does one bottle cost? Find the Unit Rate.

so I am solving based on '12 fl. oz.' bottles costing $84.

Answer:

unit rate = 7 $ per fl. oz.

Therefore, the 7 $ per fl. oz is the unit rate.

Step-by-step explanation:

We know that a unit rate is basically a fraction (also called ratio) between two different units with a denominator of 1.

For example, kilometers per hour, and heartbeats per minute, etc.

Here, I assume, by 'unit rate' means you mean to say 'cost per fl. oz.'

Given

The cost of 12 fl. oz. bottlers = cost $84

The cost of 1 bottle cost = $84 ÷ 12 oz = 7 $ per fl. oz.

Hence,

unit rate = 7 $ per fl. oz.

Therefore, the 7 $ per fl. oz is the unit rate.

3
If QR I ST, determine and state the value of x.

Answers

Answer:

E. -1/2

Step-by-step explanation:

When two lines are said to be perpendicular to each other, the slope of one is the negative reciprocal of the other.

Therefore, given that [tex] \frac{x - 1}{4} [/tex] is the slope of [tex] \overline{QR} [/tex], and ⁸/3 is the slope of [tex] \overline{ST} [/tex], if both lines are perpendicular, it means that the slope of [tex] \overline{ST} [/tex] would be the negative reciprocal of the slope of [tex] \overline{QR} [/tex].

Therefore:

[tex] \frac{x - 1}{4} = -\frac{3}{8} [/tex]

Cross multiply

[tex] (x - 1)(8) = (-3)(4) [/tex]

[tex] 8x - 8 = -12 [/tex]

Add 8 to both sides

[tex] 8x = -12 + 8 [/tex]

[tex] 8x = -4 [/tex]

Divide both sides by 8

[tex] x = \frac{-4}{8} [/tex]

[tex] x = \frac{-1}{2} [/tex]
