Answers

Answer 1

Question:

Solution:

The situation of the given problem can be drawn in the following right triangle:

This problem can be solved by applying the trigonometric identities as this:

[tex]\tan(2^{\circ})=\frac{y}{10}[/tex]

solving for y, this is equivalent to:

[tex]y\text{ = 10 tan\lparen2}^{\circ}\text{\rparen=0.349 miles}[/tex]

now, 0.349 miles is equivalent to 1842.72 feet. Now, this number rounded to the nearest whole foot is equivalent to 1843.

Then, the correct answer is:

1843 feet.

the top of a rectangular box has an area of 42cm^2. The sides of the box have areas of 30cm^2 and 35cm^2. what are the dimensions of the box?

Answers

We have a rectangular box where we know the area of the faces and we have to find the width w, length l and height h.

The area of the top of the box is equal to the length times the width (l*w) and we also know that it is 42 cm², so we can write:

[tex]l\cdot w=42[/tex]

With the same logic, we can write the equations for the other two areas:

[tex]\begin{gathered} l\cdot h=30 \\ w\cdot h=35 \end{gathered}[/tex]

NOTE: the area we choose for l or w is indistinct,so we can relate it as we like.

Then, we can solve this system of equations substituting variables as:

[tex]\begin{gathered} l\cdot h=30\longrightarrow l=\frac{30}{h} \\ w\cdot h=35\longrightarrow w=\frac{35}{h} \\ l\cdot w=(\frac{30}{h})(\frac{35}{h})=\frac{1050}{h^2}=42 \\ h^2=\frac{1050}{42} \\ h^2=25 \\ h=\sqrt[]{25} \\ h=5 \end{gathered}[/tex]

With the value of h, we can calculate l and w:

[tex]\begin{gathered} l=\frac{30}{h}=\frac{30}{5}=6 \\ w=\frac{35}{h}=\frac{35}{5}=7 \end{gathered}[/tex]

Answer:

The dimensions of the box are: length = 6 cm, width = 7 cm and height = 5 cm.

Triangle A B C has vertices (1,4),(5,6) and (3,10) It is reflected across the y axis forming triangle A’B’C’. What are the vertices of the new triangle?

Answers

Given:

The coordinates of triangle ∆ABC are (1,4), (5,6) and (3,10).

The triangle is reflected across y axis forming ∆A'B'C'.

The objective is to find the vertices of the new triangle.

Explanation:

If a triangle with coordinate (a,b) is reflected across y axis, then the change in reflected coordinate will be (-a,b).

If a triangle with coordinate (a,b) is reflected across x axis, then the change in reflected coordinate will be (a,-b).

To find vertices:

Since, the given triangle is reflected across y axis, then the vertices of new triangle will be,

[tex]\begin{gathered} A^{\prime}=(-1,4) \\ B^{\prime}=(-5,6) \\ C^{\prime}=(-3,10) \end{gathered}[/tex]

Hence, the vertices of the new triangle are (-1,4), (-5,6) and (-3,10).

Given: The cost of renting a canoe is $6.50 per hour in addition to a $25 deposit.

Required: If the family rented the canoe from 12:30 PM-3:30 PM, write and solve a linear equation to find the total cost to rent the canoe.

Explanation: Let x denote the number of hours the family rented the canoe. Then the linear equation representing the total cost of renting the canoe is given by-.

[tex]Cost,\text{ }C=6.50x+25[/tex]

8. Find the area of the shaded portion of the figure. 10.5cm

Answers

The area = area of the big rectangel - sum of the areas of the two circles

the diameter of each of the circles is 10.5cm

Hence, each circle has a radius of 10.5cm / 2 = 5.25cm

The length of the rectangle = the sum of the diameters of the circles

Therefore

The length of the rectangle = 10.5cm + 10.5cm = 21cm

The width of the rectangle = 10.5cm

Hence,

[tex]\begin{gathered} \text{area of shaded portion = 21}\times10.5\text{ - (}\pi\times5.25^2+\pi\times5.25^2) \\ =220.5-(55.125\pi)\approx47.32 \end{gathered}[/tex]

find the 8th term of geometric sequence where a1=5, r= -2

Which equation represents a line which is perpendicular to the line y - 6x = -3? Submit Answer Oy= 6x +3 Oy= 1/6x +4 O y= - 1/6x + 8 O y = -6x + 2

Answers

When we have two perpendicular lines their slopes are opposite and inverse.

In this case, we have the equation of the line:

y-6x= -3

Let's solve for y and arrange this equation to make it look like the general form of a linear equation: y=mx+b, where m is the slope of the line.

y-6x= -3

y-6x+6x= -3+6x

y= 6x-3

As we can see, the number that is multiplying the x variable in our equation is 6, the slope of this line is 6.

As mentioned, a perpendicular line to the line y= 6x-3 would have a slope opposite and inverse, then the slope of the line perpendicular to the first line (m2) would be:

[tex]m2=-\frac{1}{6}[/tex]

from the options that we have, we can see that the only line that has a slope of -1/6 is the line y= -1/6+8, so that is the right option.

We are to find the positive and negative angles that are coterminal with

By definition

Coterminal Angles are angles that share the same initial side and terminal sides. Finding coterminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians

Hence,

The positive coterminal angle is

[tex]\frac{2\pi}{3}+2\pi[/tex]

Simplifying this we get

[tex]\begin{gathered} \frac{2\pi}{3}+2\pi \\ =\frac{2\pi+6\pi}{3} \\ =\frac{8\pi}{3} \end{gathered}[/tex]

Therefore, the positive coterminal angle is

[tex]\frac{8\pi}{3}[/tex]

The negative coterminal angle is

[tex]\begin{gathered} \frac{2\pi}{3}-2\pi \\ =\frac{2\pi-6\pi}{3} \\ =-\frac{4\pi}{3} \end{gathered}[/tex]

Therefore, the negative coterminal angle is

What is consecutive integer ?

   Integers that follow one another are referred to as consecutive integers. They proceed in a certain order or sequence. For instance, a sequence of natural numbers are all integers. In mathematics, the term "consecutive" refers to an uninterrupted chain of events or a continuous progression, such as when integers follow one another in a sequence where each succeeding number is one more than the one before it. The mean and median are both identical in a collection of successive integers (or in numbers). x + 1 and x + 2 are two consecutive integers if x is an integer.

Here sum of six consecutive integer is -9.

Let us take the 6 consecutive numbers are,

=> x,x+1, x+2, x+3,x+4, x+5

Now sum is -9. Then ,

=> x+x+1+x+2+x+3+x+4+x+5 =-9

=> 6x + 15 = -9

=> 6x = -9-15

=> 6x = -24

Explanation

The question wants us to solve the simultaneous equation

4y - 3x = -16

8x - 4y = 24

Adding the two equations, we have,

4y - 3x + 8x - 4y = -16 + 24

5x = 8

Divide both sides by 5

(5x/5) = (8/5)

x = 1.6

If x = 1.6,

8 (1.6) - 4y = 24

12.8 - 4y = 24

-4y = 24 - 12.8

-4y = 11.2

How to determine the y-intercept of the trend line?

In order to determine a linear equation of the trend line that models the data points contained in the table, we would have to use an Excel regression calculator (scatter plot).

In this scenario, the teams’ number of runs would be plotted on the x-axis of the scatter plot while the teams’ number of wins would be plotted on the y-axis of the scatter plot.

On the Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the trend line on the scatter plot.

From the scatter plot (see attachment) which models the relationship between data points in the table, a linear equation of the trend line is given by:

y = 0.15x - 23.08

In conclusion, a standard linear equation is given by:

y = mx + c

Where:

[tex]6y=24[/tex]

Dividing both sides by 6, we finally have:

[tex]\frac{6}{6}y=\frac{24}{6}\rightarrow y=4[/tex]

Therefore, the value for y = 4.

use the given graph to find the mean, median and mode of the following distribution: the mean is _______the median is _______the mode(s) is/are: __________Note: when the data is presented in a frequency table, the formula to find the mean is:

Answers

Solution:

Given:

From the graph above, a frequency table can be made as shown below;

To calculate the mean;

[tex]\begin{gathered} \text{Mean}=\frac{\Sigma fx}{\Sigma f} \\ \text{Mean}=\frac{189}{20} \\ \text{Mean}=9.45 \end{gathered}[/tex]

Therefore, the mean is 9.45

To calculate the median;

Median is the middle term when the data is arranged in rank order.

Since we have 20 terms, then the middle terms will be the 10th and 11th terms.

The median will be the mean of these two numbers.

[tex]\begin{gathered} 10th\text{ term=9} \\ 11th\text{ term=10} \\ \text{Median}=\frac{9+10}{2} \\ \text{Median}=\frac{19}{2} \\ \text{Median}=9.5 \end{gathered}[/tex]

Therefore, the median is 9.5

To calculate the mode;

The mode is the data that appears most in the set. It is the data with the highest frequency.
