The length of a rectangle is 5 times its width if the perimeter is at most 96 cm what is the greatest possible value for the width

Answers

Answer 1

The value of the width in the rectangle is 8cm.

How to calculate the width?

Based on the information, let the width be represented as w.

Let the width be represented as 5 × w = 5w

Perimeter = 96cm

Perimeter of a rectangle = 2(length + width)

Perimeter = 2(5w + w)

96 = 12w

Divide

w = 96/12

w = 8

The value of the width is 8cm.

Find an equation of the line through (1,8) and parallel to y = 4x + 8.y=(Type your answer in slope-intercept form.)

Answers

First of all, remember that parallel lines are those with equivalent slope. So, the given line is

[tex]y=4x+8[/tex]

If the new line we have to find is parallel to this one, that means the slope is

[tex]m=4[/tex]

Because the coefficient of x is always the slope.

Now, we know that the new line must pass through (1,8) and it must have a slope of 4. We can use the point-slope formula

[tex]y-y_1=m(x-x_1)[/tex]

Replacing the point and the slope, we have

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

Then, we solve for y

[tex]y=4x-4+8\rightarrow y=4x+4[/tex]

Therefore, the new parallel line is

[tex]y=4x+4[/tex]

What is an equation for each translation of y=|x|?1. 4 units up2. 7 units down

Answers

To find an equation for each translation, keep in mind this:

f(x); g(x)=f(x)+a, the function is translated a units up.

f(x); g(x)=f(x)-a, the function is translated a units down.

Use this information to find the equation for each translation.

4 units up - Add 4 units to the function:

The graph below shows a company’s profit f(x) in dollars, depending on the price of goods x, in dollar’s, being sold by the company: Part A: What do the x-intercepts and maximum value of the graph represent in context of the disrobed situation?Part B: What are the intervals where the function is increasing and decreasing, and what do they represent about the sale and profit for the company in the situation described?Part C: What is an approximate average rate of change of the graph from x=1 to x=3, and what does this rate represent in context of the described situation?

Answers

We will have the following:

Part A:

The x-intercepts represent the prices of the goods than wen sold represent no net gain or loss.

The maximum value represents the price at which there will be a maximum profit.

Part B:

We will have that the increasing and decreasing intervals are respectively:

[tex]I_{\text{increaing}}=(-\, \infty,3)[/tex][tex]I_{\text{decreasing}}=(3,\infty)[/tex]

They tells us respectively that:

Increasing: The greater the price the greater the profit.

Decreasing: The greater the price the smaller the profit.

Part C:

We determine the equation of the parabola. We can see that it's vertex is located at (3, 120), we can also see that the parabola passes by the origin (0, 0); so:

[tex]f(x)=a(x-3)^2+120\Rightarrow0=a(0-3)^2+120[/tex][tex]\Rightarrow0=9a+120\Rightarrow9a=-120\Rightarrow a=-\frac{40}{3}[/tex]

So, the equation that represents the parabola is:

[tex]f(x)=-\frac{40}{3}(x-3)^2+120[/tex]

Then, we will determine the average rate of change as follows:

[tex]\text{average rate of change}=\frac{f(b)-f(a)}{b-a}[/tex]

So:

[tex]\text{average rate of change}=\frac{(-40/3((3)-3)^2+120)-(-40/3((1)-3)^2+120)}{3-1}[/tex][tex]\text{average rate of change}=\frac{80}{3}\Rightarrow average\text{ rate of change}\approx26.67[/tex]

So, the avereage rate of change for the graph from x = 1 to x = 3 is exactly 80/3, that is approximately 26.67.

Answers

In order to determine the best description, first count the number of times for heads h and tails t.

Based on the given information, the number of heads was h = 6 and the number of tails was t = 18.

The theoretical probability in this case results in a 50% of probability for both events, that is, for 24 times at which the coin was flipped, 12 would be tail and 12 would be head.

Then, based on the previous explanation, you can conclude that:

Two trees are leaning on each other in the forest. One tree is 19 feet long and makes a 32° angle with the ground. The second tree is 16 feet long.What is the approximate angle, x, that the second tree makes with the ground?

Answers

39º

1) Considering what's been given we can sketch this out:

From these trees leaning on each other, we can visualize a triangle (in black).

2) So now, since we need to find the other angle, then we need to apply the Law of Sines to find out the missing angle:

[tex]\begin{gathered} \frac{a}{\sin(A)}=\frac{b}{\sin (B)} \\ \frac{16}{\sin(32)}=\frac{19}{\sin (X)} \\ 16\cdot\sin (x)=19\cdot\sin (32) \\ \frac{16\sin(X)}{16}=\frac{19\sin (32)}{16} \\ \sin (X)=\frac{19\sin(32)}{16} \\ \end{gathered}[/tex]

As we need the measure of the angle, (not any leg) then we need to use the arcsine of that quotient:

[tex]\begin{gathered} X=\sin ^{-1}(\frac{19\cdot\sin (32)}{16}) \\ X=38.996\approx39 \end{gathered}[/tex]

3) Hence, the approximate measure of that angle X is 39º

What is the probability of choosing a random number from this group that is less than or equal to 8000? Enter a fraction or round your answer to 4 decimal places, if necessary.

Answers

First, we need to determine the total amount of numbers fulfilling the conditions:

- 4 digits

- Not starting with 0

For the first digit, we have then 9 possible numbers: 1, 2, 3, 4, 5, 6, 7, 8 and 9.

For the second, third and fourth, we have 10 possible numbers 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.

Then, to determine the amount of numbers available we just need to multiply the possibilities for each digit:

[tex]9\cdot10\cdot10\cdot10=9000[/tex]

Then, randomly choosing one of the given numbers, we have 9000 possible outcomes. Those will be numbers from 1000 to 9999.

Now we just need to determine how many numbers among those 9000 are lower than or equal to 8000.

As the numbers start in 1000, we have 7001 cases where the randomly selected number is lower than or equal to 8000.

We obtain 7001 since 8000 - 1000 = 7000 but we need to consider also the number 1000.

The probability will be then:

1 ptsQuestion 5Jane started jogging 5 miles from home, at a rate of 2 mph. Write the slope-intercept form of an equation for Jane's position relative to home.

Answers

Answer

[tex]y=2x+5[/tex]

SOLUTION

Problem Statement

The question wants us to model the distance Jane is from her home given her initial starting point (5 miles from home) and her speed (2 mph)

Explanation

To solve the question, we simply need to model her jogging using the equation of a line.

The general equation of a line is given as:

[tex]\begin{gathered} y=mx+c \\ \text{where,} \\ m=\text{slope}=\text{this represents Jane's speed} \\ c=y-\text{intercept}=\text{this represents her initial position from her home} \\ x=\text{time taken for Jane to move} \\ y=\text{Jane's final position after moving for time, x} \end{gathered}[/tex]

We have been told that her speed is 2 mph. Thus, m = 2. We have also been given her initial position from her house to be 5 miles.

Jane starts jogging 5 miles from her home, thus, her position relative to her home will continue to increase as she jogs on at 2 mph. Thus, c = 5 and NOT -5.

This means we can write the equation for her position is:

[tex]\begin{gathered} m=2,c=5 \\ \therefore y=2x+5 \end{gathered}[/tex]

What is the length of the side of an equilateral triangle if the height is 9√3

Answers

An equilateral triangle is a triangle were all the sides have the same measurement, and all the angles are the same(60º).

The height of an equilateral triangle divides the triangle into two equal right triangles. The height represents the oposite side of the angle of 60º, and the hypotenuse has the length of the side of the equilateral triangle, if we find the hypotenuse we have our answer.

Using trigonometric relations on the right triangle, we can find the value for the hypotenuse. The ratio between the opposite side to an angle and the hypotenuse is equal to the sine of this angle. If we call the hypotenuse as h, we have the following relation

[tex]\sin (60^o)=\frac{9\sqrt[]{3}}{h}[/tex]

The sine of 60º is a known value

[tex]\sin (60^o)=\frac{\sqrt[]{3}}{2}[/tex]

Then, combining both expressions, we have

[tex]\frac{9\sqrt[]{3}}{h}=\frac{\sqrt[]{3}}{2}[/tex]

Solving for h

[tex]\begin{gathered} \frac{9\sqrt[]{3}}{h}=\frac{\sqrt[]{3}}{2} \\ \frac{9}{h}=\frac{1}{2} \\ \frac{h}{9}=2 \\ h=18 \end{gathered}[/tex]

The length of the side of an equilateral triangle if the height is 9√3 is equal to 18.
