Find The Length Side

Answers

Answer 1

Answer:

PR = 6.93 units

PQ = 13.86 units

Step-by-step explanation:

From ΔPQR,

m∠Q = 30°

QR = 12

By applying tangent rule for the given angle in the triangle,

tan(30°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(30°) = [tex]\frac{PR}{QR}[/tex]

[tex]\frac{1}{\sqrt{3}}=\frac{PR}{12}[/tex]

PR = [tex]\frac{12}{\sqrt{3} }[/tex]

PR = 4√3 ≈ 6.93

Now we apply cosine rule,

cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{\sqrt{3} }{2}=\frac{QR}{PQ}[/tex]

[tex]\frac{\sqrt{3} }{2}=\frac{12}{PQ}[/tex]

PQ = [tex]\frac{24}{\sqrt{3} }[/tex]

PQ = 8√3 ≈ 13.86

Answers

Answer:

f(n)=45⋅(4/5)^n−1
complete the recursive formula of f(n)

Answers

F(1) = 45

f(n) = f(n-1) * 4/5

Step-by-step explanation:

f(n) = 45 x (4/5)ⁿ⁻¹

f(1) = 45 x (4/5)¹⁻¹ = 45 x (4/5)⁰ = 45 x 1 = 45

f (n-1) = 45 x (4/5)ⁿ⁻¹⁻¹ = 45 x (4/5)ⁿ⁻²

f(n) = f(n-1) * (4/5)¹ = 45 x (4/5) ⁿ⁻²⁺¹ = 45 x (4/5)ⁿ⁻¹

Write an equation of a line that goes thru the points (-2, 6) & (3, -4)

Answers

Answer:

y= -2x +2

Step-by-step explanation:

The equation of a line can be written in the form of y= mx +c, where m is the gradient and c is the y-intercept. This form is known as the slope-intercept form.

To find the value of m, use the gradient formula below:

[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]

[tex]m = \frac{6 - ( - 4)}{ - 2 - 3}[/tex]

[tex]m = \frac{6 + 4}{ - 5} [/tex]

[tex]m = \frac{10}{ - 5} [/tex]

m= -2

Substitute m= -2 into the equation:

y= -2x +c

To find the value of c, substitute any pair of coordinates that the line passes through into the equation. Here, I am going to substitute the coordinates (3, -4).

y= -2x +c

When x= 3, y= -4,

-4= -2(3) +c

-4= -6 +c

c= -4 +6

c= 2

Thus, the equation of the line is y= -2x +2.

The sum of any two sides must be greater than the other to be it triangle thus it will not be a triangle so option (D) is correct.

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180°.

For any triangle, the sum of any two sides must be greater than the then third side.

As per the given sides,  11, 13, 25

11 + 13 < 25

24 < 25 so it will not a triangle.

Hence "The sum of any two sides must be greater than the other to be it triangle thus it will not be a triangle".

PLZZZZZZZ HELP 50 POINTS FAST Assignment SummaryFor this assignment, you will ask questions about the factors that have caused a rise in global temperatures over the past century. Then, you will conduct research to answer your questions. You will also graph provided information, analyze the graphs, and make conclusions based on the graphs. Finally, you will write a paper describing the conclusions of your research and graphs.Background InformationGlobal temperature change is a gradual increase in the overall temperature of the Earth's atmosphere. Both human activity and natural processes have contributed to this temperature increase. Examples of human activities include the burning of fossil fuels, cement production, and agricultural activity. Examples of natural processes include changes in incoming solar radiation and volcanic activity.Scientists present evidence for the rise in global temperature in the form of tables, graphs, maps, and models. For example, scientists build climate models (computer simulations of climate systems) to explore the causes and effects of global temperature change and to predict future trends. These models predict that the Earths average surface temperature will rise as greenhouse gas concentrations continue to rise. Based on these models, scientists predict that average surface temperatures could rise by between 2C and 6C by the end of the 21st century.Step 2: Write your questions.You are familiar with some of the factors that have contributed to the rise in global temperatures over the past century. Think of three questions that will help you clarify your understanding of how these factors lead to an increase in global temperatures. Consider the following when you come up with your questions: Ways in which natural processes and human activity have affected global temperature change over the past centuryThe influence of these processes and activities on a gradual or sudden change in global temperatureWrite your questions in the space provided at the end of this document.Have your teacher review your questions.
