Answer:

Step-by-step explanation:

The two 'slashes' on the 2 edges indicate that it's an isosceles triangle ( the base angles are equal)

Total angles in a triangle = 180.

Thus,

3x + 4x+2+4x+2= 180.

11x+4=180

11x=176

Therefore, x= 16°

Thus,

3x = 3(16) = 48°

The (4x+2)'s =

4(16)+2

=66° each.

Answer:

x = -22/3

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ (3x/2) + 12 = 1

Then the value of x will be,

→ (3x/2) + 12 = 1

→ (3x/2) + (24/2) = 1

→ (3x + 24)/2 = 1

→ 3x + 24 = 1 × 2

→ 3x + 24 = 2

→ 3x = 2 - 24

→ 3x = -22

→ [ x = -22/3 ]

Hence, value of x is -22/3.

Wei-Ling's fifteenth-generation ancestor is estimated to have around 1,220,703 descendants.

Assuming that each descendant has an average of 2.5 children, we can use the formula:

where n is the number of generations.

In this case, n = 15 (fifteenth-generation), so we can plug in the values and get:

number of descendants = [tex](2.5)^{15}[/tex]= 1,220,703.125

Therefore, Wei-Ling's fifteenth-generation ancestor is estimated to have around 1,220,703 descendants. However, it is important to note that this is just an estimation and may not be entirely accurate due to various factors such as reproductive rates and other variables.

Answer:

Step-by-step explanation:

If angles A and B are complementary, their measures add to 90º.

This means that if:

m∠B = 55º,

then:

m∠A = (90 - 55)º = 45º

Using this information, we can make the assertion that because:

55º ≠ 45º,

m∠A ≠ m∠B,

and thus:

sin(A) ≠ sin(B)

because 55º and 45º are NOT coterminal angles.

Therefore, the statement

The United States Declaration of Independence, officially The unanimous Declaration of the thirteen united States of America, is the pronouncement and founding document adopted by the Second Continental Congress meeting at Pennsylvania State House, which was later renamed Independence Hall, in Philadelphia, Pennsylvania, on July 4, 1776. Enacted during the American Revolution, the Declaration explains why the Thirteen Colonies at war with the Kingdom of Great Britain regarded themselves as thirteen independent sovereign states and no longer subject to British colonial rule. With the Declaration, the 13 states took a collective first step in forming the United States and, de facto, formalized the American Revolutionary War, which had been ongoing since April 1775.

The Declaration of Independence was signed by 56 of America's Founding Fathers who Second Continental Congress delegates from New Hampshire, Massachusetts Bay, Rhode Island and Providence Plantations, Connecticut, New York, New Jersey, Pennsylvania, Maryland, Delaware, Virginia, North Carolina, South Carolina, and Georgia. The Declaration became one of the most circulated and widely reprinted documents in early American history.

The Committee of Five drafted the Declaration to be ready when Congress voted on independence. John Adams, a leading proponent of independence, persuaded the Committee of Five to charge Thomas Jefferson with authoring the document's original draft, which the Second Continental Congress then edited. The Declaration was a formal explanation of why the Continental Congress had voted to declare its independence from Great Britain, a year after the American Revolutionary War broke out. The Lee Resolution for independence was passed unanimously by the Congress on July 2.

After ratifying the text on July 4, Congress issued the Declaration of Independence in several forms. It was initially published as the printed Dunlap broadside that was widely distributed and read to the public. Jefferson's original draft is currently preserved at the Library of Congress in Washington, D.C., complete with changes made by Adams and Benjamin Franklin, and Jefferson's notes of changes made by Congress. The best-known version of the Declaration is the signed copy now displayed at the National Archives in Washington, D.C., which is popularly regarded as the official document. This engrossed copy was ordered by Congress on July 19 and signed primarily on August 2, 1776.[2][3]

The sources and interpretation of the Declaration have been the subject of much scholarly inquiry. The Declaration justified the independence of the United States by listing 27 colonial grievances against King George III and by asserting certain natural a

(The table is in the image that is provided, if you cannot see it; I've written it down below)

Time (t): 10, 15

Number of bottles (b): 4, 6

The table shows the time it takes the machine to fill a certain number of bottles of juice. To determine if the relationship is proportional, we can look at the ratios of time to number of bottles for the different data points.

If the ratios are the same for all data points, then the relationship is proportional. In this case, we have:

Ratio for the first data point: 10/4 = 2.5

Ratio for the second data point: 15/6 = 2.5

Since the ratios are the same, we can conclude that the relationship is proportional.

The terms used in this context are: proportional relationship, table, ratio, and equivalent ratios.

Answer:

If you want to derive an equation from the question, you answer is:

3*x+4<-62

If you want the solved equation for x, your answer is:

x<-22

(Depending on what your question is)

Step-by-step explanation:

For the first answer, you can represent the unknown number as x. Three times is equivalent to 3 multiply, so it will look like 3*x, or just 3x. Increased by four is just adding four, so your equation will now look like 3x+4. Less than -62 is just 3x+4<-62. To solve future problems, just carefully look at the words. Does it mention divided by? Maybe decreased? Carefully look and analyze the question and plug in the operators, variables, and numbers.

For the second solution, since we've already translated the question to an equation from above, we can solve the equation we've derived, which is 3x+4<-62. Subtract four on both sides. The equation will look like this: 3x+4-4<-62-4. Simplifying, we get 3x<-66. Next, we divide both sides of the equation by 3, and we will get x<-22.

If there were 56 people who were all 48 years old, then the total number of years that the people had lived would be: 56 people x 48 years/person = 2,688 years

This calculation multiplies the number of individuals (56 people) by their age (48 years per person) to determine the total number of years of life experience represented by the group. In essence, it is calculating the cumulative age of everyone in the group. The result, 2,688 years, reflects the sum total of all the years that the 56 people have lived in total. Therefore, the total number of years that the people had lived is 2,688.

Answer:

Let's call the larger number "x" and the smaller number "y".

From the problem, we know that:

x + y = 38 (Equation 1)

y = x - 14 (Equation 2)

We can substitute Equation 2 into Equation 1:

x + (x - 14) = 38

2x - 14 = 38

Adding 14 to both sides:

2x = 52

Dividing both sides by 2:

x = 26

Now we can use Equation 2 to find y:

y = x - 14

y = 26 - 14

y = 12

So the two numbers are 26 and 12.

Step-by-step explanation:

Answer:

12 and 26

Step-by-step explanation:

n + b = 38 n < b b = n + 14 n + n + 14 = 38 2n = 24 n = 12 b = 12 + 14 b = 26 Your two numbers are 12 and 26

Using logarithmic identities and quadratic equation, the value of lg a * lg c is 4/3

Using logarithmic identities, we can rewrite the given equations as:

logₐa + log_b c = 4

log_b b + logₐ c = 3

Simplify the first equation using the fact that logₐa = 1/log_aₐ = 1, and simplify the second equation using the fact that log_b b = 1:

1 + log_b c = 4

1 + logₐ c = 3

Solve for log_b c and logₐ c:

log_b c = 3

logₐ c = 2

Now we can use the fact that logₐ c = logₐ (a · c)/a = logₐ a + logₐ c/a to write:

logₐ a + logₐ c/a = 2

Substitute logₐ c = 2 into this equation to get:

logₐ a + 2/a = 2

Multiply both sides by a to get:

logₐ a · a + 2 = 2a

Rearrange this equation as a quadratic equation:

logₐ a · a - 2a + 2 = 0

This quadratic has a maximum value when the coefficient of logₐ a is zero, i.e., when:

a = 2^(2/3)

Substituting this value of a into the equation logₐ c = 2, we get:

log₂ c = log₂ a^2 = 2/3 · log₂ 2^2 = 4/3

Therefore, logₐ c = log₂ c/log₂ a = (4/3) / (2/3) = 2

Finally, we can find the maximum value of logₐ a · logₐ c by multiplying logₐ a and logₐ c:

logₐ a · logₐ c = log₂ a/log₂ a · log₂ c/log₂ a = log₂ c = 4/3

Therefore, the maximum value of logₐ a · logₐ c is 4/3.

Answer:

To solve the equation 3(x+2)=17, we start by simplifying the expression on the left side by distributing the 3:

3(x+2) = 17

3x + 6 = 17

Next, we isolate the variable term by subtracting 6 from both sides:

3x + 6 - 6 = 17 - 6

3x = 11

Finally, we solve for x by dividing both sides by 3:

3x/3 = 11/3

x = 11/3

Therefore, the solution to the equation 3(x+2)=17 is x = 11/3.

To solve the equation 4x+3=2x+15, we start by simplifying the expression by combining like terms:

4x + 3 = 2x + 15

2x + 3 = 15

Next, we isolate the variable term by subtracting 3 from both sides:

2x + 3 - 3 = 15 - 3

2x = 12

Finally, we solve for x by dividing both sides by 2:

2x/2 = 12/2

x = 6

Therefore, the solution to the equation 4x+3=2x+15 is x = 6.

Step-by-step explanation:

Answer:

sin(2x) = 2sin(x)cos(x)

= 2(-3/5)(-2/5)

= 12/25

cos^2(x) = (2/√13)^2 = 4/13

sin^2(x) = (-3/√13)^2 = 9/13

cos(2x) = cos^2(x) - sin^2(x) = (4/13) - (9/13) = -5/13

= cos(2x) = -5/13

tan(2x) = 3/4

Explanation:

Given tan(x) = -3/2 and x terminates in quadrant II.

We know that tan(x) = sin(x) / cos(x)

Using this, we can find sin(x) and cos(x):

tan(x) = sin(x) / cos(x) = -3/2

cos(x) = -2/√13

sin(x) = 3/√13

Using double angle formulas, we can find sin(2x), cos(2x), and tan(2x):

sin(2x) = 2sin(x)cos(x) = 2(3/√13)(-2/√13) = -12/13

cos(2x) = cos²(x) - sin²(x) = (-2/√13)² - (3/√13)² = 4/13 - 9/13 = -5/13

tan(2x) = (2tan(x)) / (1 - tan²(x)) = (2(-3/2)) / (1 - (-3/2)²) = 3/4

We know that tan(x) = -3/2 and x is in quadrant II. Therefore, we can use the Pythagorean theorem to find the opposite side (y) and the hypotenuse (r) of a right triangle with an angle of x in quadrant II.

Let r = 2, so y = -3 and x = arctan(-3/2) ≈ -56.31°.

Using the double angle formulas:

sin(2x) = 2sin(x)cos(x) = 2(-3/2)(√5/2) = -3√5/2

cos(2x) = cos²(x) - sin²(x) = (√5/2)² - (-3/2)² = (5-9)/4 = -1/2

tan(2x) = 2tan(x)/(1-tan²(x)) = 2(-3/2)/(1-(-3/2)²) = 3/4

So, the answers are: sin(2x) = -3√5/2, cos(2x) = -1/2, and tan(2x) = 3/4.

The function represents the height of the plant in centimetres after n days, so n cannot be negative.

Part A:

To find a reasonable domain to plot the growth function, we need to consider the practical limitations of the growth of the plant. Also, since the function represents the growth of a particular species of plant, there may be an upper limit to how many days the plant can grow.

Assuming that the plant is not a perennial plant and has a limited lifespan, we can choose a reasonable domain for the function as [0, t], where t is the expected lifespan of the plant in days.

Since we do not have information about the expected lifespan of the plant, we can choose a reasonable value such as [tex]t = 365[/tex]  (assuming it is an annual plant). So the domain for the function can be  [tex][0, 365][/tex]  .

Part B:

The y-intercept of the graph of the function f(n) represents the height of the plant when it was planted or started growing, that is, at n = 0. To find the y-intercept, we can substitute n = 0 in the equation:

[tex]f(0) = 15(1.02)^0 = 15[/tex]

Therefore, the y-intercept of the graph of the function f(n) is [tex]15[/tex] cm.

Part C:

The average rate of change of the function f(n) from n = 1 to n = 4 can be calculated using the formula:

average rate of change [tex]= [f(4) - f(1)] / (4 - 1)[/tex]

Substituting the values in the equation, we get:

average rate of change [tex]= [15(1.02)^4 - 15(1.02)^1] / 3[/tex]

average rate of change [tex]≈ 1.42 cm/day[/tex]

Therefore, The average rate of change of the function f(n) from n = 1 to n = 4 represents the average daily growth rate of the plant during this period.

Step-by-step explanation:

The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle and π is a mathematical constant approximately equal to 3.14.

In this case, the radius of the tire is 20 inches. So, the circumference of the tire is:

C = 2πr

C = 2π(20)

C = 40π

Therefore, the circumference of the tire is 40π inches, or approximately 125.66 inches if you round to two decimal places.

According to given conditions, the biggest number is 46.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as 1 : 3 (for every one boy there are 3 girls).

Let the two numbers in the first ratio be 3x and 5x, where x is some constant of proportionality.

According to the problem, if we subtract 9 from each number, the new ratio is 12:23. So, we have:

(3x - 9) : (5x - 9) = 12 : 23

We can cross-multiply to get:

23(3x - 9) = 12(5x - 9)

Simplifying this equation, we get:

69x - 207 = 60x - 108

9x = 99

x = 11

So, the two numbers in the first ratio are 3x = 33 and 5x = 55.

To find the biggest number, we need to determine which of these numbers is larger after subtracting 9.

33 - 9 = 24

55 - 9 = 46
