what is the circumference of a circular pond with a radius of 14 meters?

Answers

Answer 1
You are given the radius which is the distance from a side of the circle to its center. This length is 14.
The circumference of a circle is calculated by 2πr
2π14 2*14=28
So it can be either 28π or you can take the first digits of π which are 3.1415 and multiply that by 28
28*3.1415= 87.96
Therefore you end up with 2 different answers...
87.96 or 28π

What is the measure of AC ? Enter your answer in the box. ° Circle with inscribed angle A B C. Angle A B C is 3 x minus 1.5 degrees. The intercepted arc A C is 3 x plus 9 degrees.

Answers

Inscribed angles are 1/2 of the measure of the intercepted arc.  That means from this we have the equation
[tex](3x-1.5)=\frac{1}{2}(3x+9)[/tex].  Distribute the 1/2:
[tex]3x-1.5=\frac{1}{2}*3x+\frac{1}{2}*9 \\3x-1.5=\frac{1}{2}*\frac{3x}{1} + \frac{1}{2}*\frac{9}{1} \\3x-1.5=\frac{3x}{2}+\frac{9}{2} \\3x-1.5=1.5x+4.5[/tex]
We cannot have a variable on both sides of the equation, so cancel the 1.5x to avoid negatives:
[tex]3x-1.5-1.5x=1.5x+4.5-1.5x[/tex]
Combine like terms:
[tex]1.5x-1.5=4.5[/tex]
Cancel the -1.5 by adding:
[tex]1.5x-1.5+1.5=4.5+1.5 \\1.5x=6[/tex]
Divide both sides by 1.5:
[tex]\frac{1.5x}{1.5}=\frac{6}{1.5} \\x=4[/tex]
Since AC is 3x+9, we substitute 4 in for x:
3*4+9=12+9=21°

Use the Inscribed Angle theorem to get the measure of AC. The intercepted arc AC is [tex]21^{\circ}[/tex].

Given,

The inscribed angle [tex]\angle ABC[/tex] is [tex]3x-1.5[/tex].

And the Intercepted arc AC is [tex]3x+9[/tex].

What is the Inscribed Angle theorem?

We know that, Inscribed Angle Theorem stated that the measure of an inscribed angle is half the measure of the intercepted arc.

So,

[tex]3x-1.5=\frac{1}{2} (3x+9)[/tex]

[tex]2 (3x-1.5)=3x+9[/tex]

[tex]6x-3.0=3x+9[/tex]

[tex]6x-3x=9+3[/tex]

[tex]3x=12\\x=4[/tex]

Since the intercepted arc AC is [tex]3x+9[/tex], putting the value of [tex]x=4[/tex] we get,

intercepted arc AC is [tex]21^{\circ}[/tex].

Hence the intercepted arc AC is [tex]21^{\circ}[/tex].

find the measures of two angles one positive and negative that are coterminal with pi/2

Answers

Answer:  The required measures of two angles one positive and negative that are co-terminal with [tex]\dfrac{\pi}{2}[/tex] are [tex]-\dfrac{3\pi}{2}[/tex] and [tex]\dfrac{5\pi}{2}.[/tex]

Step-by-step explanation:  We are given to find measures of two angles one positive and negative that are co-terminal with [tex]\dfrac{\pi}{2}.[/tex]

Let x and y represents the positive and negative co-terminal angles respectively.

We know that

the measures of any two co-terminal angles differ from each other by a multiple of [tex]2\pi.[/tex]

So, the values of x and y can be found as follows :

[tex]x=\dfrac{\pi}{2}-2\pi=-\dfrac{3\pi}{4},\\\\\\y=\dfrac{\pi}{2}+2\pi=\dfrac{5\pi}{2}.[/tex]

Thus, the required measures of two angles one positive and negative that are co-terminal with [tex]\dfrac{\pi}{2}[/tex] are [tex]-\dfrac{3\pi}{2}[/tex] and [tex]\dfrac{5\pi}{2}.[/tex]

Final answer:

The positive coterminal angle with π/2 is 5π/2, and the negative coterminal angle is -3π/2; both angles are found by adding and subtracting 2π radians from the original angle.

Explanation:

To find the measures of two angles, one positive and one negative, that are coterminal with π/2, we need to add and subtract 2π (360 degrees) to the original angle since the angles are coterminal when they share the same initial and terminal sides and differ by a full circle (360 degrees) or a multiple thereof. The angle π/2 radians is equivalent to 90 degrees, so adding 2π radians (360 degrees) gives us a positive coterminal angle, and subtracting 2π radians (360 degrees) gives us a negative coterminal angle.

Positive coterminal angle: π/2 + 2π = 5π/2.

Negative coterminal angle: π/2 - 2π = -3π/2.

Due to his good credit history, Francis was able to purchase a home with a good interest rate on his loan. Assuming Francis has the ability to choose the length of his loan and the amount of the down payment, what method would help Francis decrease the total cost of the loan? Select the best answer from the choices provided. reducing the down payment increasing the length of the loan increasing the length of the loan and reducing the down payment reducing the length of the loan and increasing the down payment

Answers

Answer:
Reducing the length of the loan and increasing the down payment.

Explanation:
Increasing the down payment will reduce the total amount you will owe to the bank so there will be less interest charges.

The smaller the term, the higher the interest rate but the smaller the time the less the bank will actually receive from you.

Answer:

Reducing the length of the loan and increasing the down payment

Step-by-step explanation:

Assuming Francis has the ability to choose the length of his loan and the amount of the down payment.

The method that would help Francis to decrease the total cost of the loan is - reducing the length of the loan and increasing the down payment.

When a person pays more amount in down payment, then he will have to loan out a smaller amount. And he will have to pay less interest. If the loan is short, the interest to be paid will be less. If the loan term is long, the interest also increases. One has to pay interest for the whole tenure of the loan.

So, if someone wants to reduce the loan amount, he must pay more in down payment.

Fifty people are surveyed at a state fair. Of the 50 people, 30 like funnel cake and 25 like fried oreos. Twenty people like both funnel cakes and fried oreos. Use a Venn Diagram to organize the data and answer the questions. How many people like either funnel cake or fried oreos?

Answers

How many people like either funnel cake or fried Oreos?
55

When using a Venn diagram to determine how many people like either funnel cake or fried Oreos out of a survey of 50, after subtracting the 20-person overlap from each individual preference to avoid double counting, the total number liking either is found to be 35 people.

To determine how many people like either funnel cake or fried Oreos, we need to use the concept of set union from Venn diagrams. First, we draw two overlapping circles, one for people who like funnel cake and another for those who like fried Oreos.

The overlapping area represents people who like both. Given that 30 people like funnel cake and 25 like fried Oreos, with a 20-person overlap liking both, we add the individual preferences and subtract the overlap to avoid double counting.

The representation is:

Number liking funnel cake only: 30 - 20 = 10

Number liking fried Oreos only: 25 - 20 = 5

Number liking both: 20

Adding these, the total number liking either funnel cake or fried Oreos is 10 + 5 + 20 = 35 people.

I originally chose A, but that was incorrect on my quiz.

Answers

B would be the right one

F(x) = (x+2)^3 = the highest power for this type turn out will be x^3
the other part is (x^2 - 7x + 3)^4, the highest power for this part will be x^8
since (x+2)^3(x^2-7x +3)^4 = the highest power of first part x^3 second part x^8
x^3 * x^8 = x^11 that result in 11 roots
This type of math, you don't need to configure the whole problem, you just need to know the basic rules of power of a number. For example, (x^2)^3, then 2*3 = 6 make x^6.
or x^2 * x^3 = x^2 + 3 = x^5.

Darlene's Caillou's 8 gallons of gasoline to travel 340 miles at mechanic work on the car and use 7 gallons of gasoline to travel 350 miles if the price of gasoline was approximately $4 per gallon how much less to the nearest cent per get a smile that it cost to run after the mechanic work on it

Answers

Before mechanic:
340 miles with 8 gallons.
A gallon costs $4, so 8 gallons cost 8 * $4 = $32.
$32 per 340 miles = $32/340 = $0.0941/mile = 9.4 cents/mile

After mechanic:
350 miles with 7 gallons.
7 gallons cost 7 * $4 = $28.
$28 per 350 miles = $28/350 = $0.08/mile = 8 cents/mile

The difference is 9.4 - 8 = 1.4.
To the nearest cent, round 1.4 to 1.

Answer: After the mechanic, it cost 1 cent per mile less to run the car.

Graph the solution for the following system of inequalities. Click on the graph until the correct solution is displayed. 2x + y < 0 y ≥ -4 - 2x



Answers

Keep clicking until it looks like this.

The graph for these inequalities intersects at point (0,0).


The graph displays the solution to the system of inequalities: 2x + y < 0 and y ≥ -4 - 2x. Here's a breakdown:

First Inequality (2x + y < 0):

This translates to a blue line with a negative slope. Points like (0, -2) and (3, -6) lie on this line.
We shade the region below this line because the inequality specifies "less than." Points there, like (1, -5), satisfy the inequality.
Second Inequality (y ≥ -4 - 2x):

This translates to a green line with a negative slope as well. Points like (0, -4) and (2, -8) lie on the line.
Unlike the first, we shade the region above this line because the inequality specifies "greater than or equal to." Points like (1, -3), above the line, satisfy the inequality.
Combined Solution:

The solution space is the overlap where both inequalities hold true. This is the triangular region shaded in both blue and green. Points within this region, like (1, -5), satisfy both inequalities.
Checking Points:

If unsure about shading, test points outside the shaded region. For example, point (0, 0) lies above both lines, satisfying both inequalities. This confirms the shading is correct.

how many triangles have the following measurements? A=38, a=432, b=382

Answers

There is only one such triangle.

_____
You know this because the given angle is opposite the longest given side. You only have ambiguous cases if the given angle is opposite the shorter of two given sides.

Using the Law of Sines, we determined that it is possible to form one triangle with the given measurements A=38°, a=432, and b=382. The calculation includes finding angle B and angle C, ensuring all triangle conditions are met.

To determine how many triangles can have the given measurements (A=38°, a=432, b=382), we need to check if these values satisfy the triangle inequalities and if they can form a possible triangle using the Law of Sines.

First, let's use the Law of Sines which states that:

sin(A)/a = sin(B)/b = sin(C)/c

Given:

A = 38° (angle)a = 432 (side opposite to angle A)b = 382 (side opposite to angle B)

We can calculate angle B using:

sin(B) = (b × sin(A)) / a

sin(B) = (382 × sin(38°)) / 432 ≈ 0.556

Finding the arc sine of 0.556, we get:

B ≈ 33.8°

Now, we find angle C:

C = 180° - A - B ≈ 180° - 38° - 33.8° = 108.2°

Using the Law of Sines again to find side c:

c = (a × sin(C)) / sin(A)

c = (432 × sin(108.2°)) / sin(38°) ≈ 676.85

Thus, it's possible to form one such triangle with the given conditions.
