Your question isn't clear; However, I'll solve in two ways
1. Diameter = 14 cm
2. Radius = 14 cm
When Diameter = 14 cm
Given
[tex]Area = \pi r^2[/tex]
[tex]Diameter = 14cm[/tex]
Required
Calculate the area of the circle
First, the radius has to be solved;
[tex]Radius = \frac{1}{2} Diameter[/tex]
[tex]Radius = \frac{1}{2} * 14cm[/tex]
[tex]Radius = 7cm[/tex]
Using the given formula;
The area is as follows
[tex]Area = \pi r^2[/tex]
[tex]Area = 3.14 * 7^2[/tex]
[tex]Area = 3.14 * 49[/tex]
[tex]Area = 153.86cm^2[/tex]
When Radius = 14 cm
Given
[tex]Area = \pi r^2[/tex]
[tex]Radius = 14cm[/tex]
Required
Calculate the area of the circle
Using the given formula;
The area is as follows
[tex]Area = \pi r^2[/tex]
[tex]Area = 3.14 * 14^2[/tex]
[tex]Area = 3.14 * 196[/tex]
[tex]Area = 615.44cm^2[/tex]

Which of the following is a true proportion of the figure based on the triangle proportionality theorem? answers: A) ab= dc B) ac=ad C) ab=ac D) bd=ca
Answer:
A) a/b = d/c
Step-by-step explanation:
The Triangle Proportionality Theorem states that if a line is parallel to one side of a triangle and it intersects the other two sides, then it divides those sides proportionally.
In this case, line TU is parallel to side QR. So, the ratios a:b and d:c are equal. In other words, a/b = d/c

John goes running every morning. He can run 3 miles in 1 hour. How many miles would he be able to run in 1 and ½ hours? A. 4.5 miles B. 2 miles C. 6 miles D. 10 miles
Answer:
2
Step-by-step explanation:
well less than 3
Answer:
A
Step-by-step explanation:
The easiest way to do this problem is to find out how far he can go in 1/2 hour.
If he goes 3 miles in 1 hour
he will go 3/2 miles in 1/2 hour
=============
Now just add this onto the distance travelled in 1 hour.
3 + 3/2 = 3 + 1.5 = 4.5
The answer is A
The answer can be obtained another (perhaps better ) way.
Set up a proportion
1 hour gives 3 miles
1.5 hours gives x
1/1.5 = 3/x Cross multiply
1*x = 1.5 * 3 Combine
x = 4.5 miles

Find the measure of each marked angle.
X degree= ? Degree
(X+50) Degree =? Degree
(180-3x) Degree =? Degree
(Simplify your answers. Type an integer or a fraction.)
Answer:
x degrees = 50 degrees.
x + 50 degrees = 50 + 50 = 100 degrees
(180 - 3x) degrees = (180 - 3*50) = 30 degrees.
Step-by-step explanation:
In a triangle, the sum of all inside angles must be 180 degrees.
In this question:
The inside angles are: x, x + 50 and 180 - 3x.
Then
x + x + 50 + 180 - 3x = 180
2x - 3x = -50
x = 50
So
x degrees = 50 degrees.
x + 50 degrees = 50 + 50 = 100 degrees
(180 - 3x) degrees = (180 - 3*50) = 30 degrees.
The function f(x) = 5 * (1/5) ^ x reflected over the yaxis. Which equations represent the reflected function? Select two options please I really need help
Answer:
The following two equations represent the reflected function:
f(x) = 5(1/5) ⁻ˣ
f(x) = 5(5)ˣ
Step-by-step explanation:
Following are two basic concepts of reflection a point or a function over an axis:
If a point or a function is reflected across x-axis, the x component remains the same while the y component changes its sign.If a point or a function is reflected across y-axis, the y component remain the same while the x component changes its sign.In this question, the function is given:
f(x) = 5(1/5)ˣ
As the function is reflected over y-axis, it follows the second concept. The x component will becomes negative.
So the equation of reflected function is:
f(x) = 5(1/5) ⁻ˣ
We know that that fraction with a negative power can also be written as a reciprocal of the same fraction with a positive power.
(1/5)⁻ˣ = 5ˣ
So equation of reflected function can also be written as:
f(x) = 5(5)ˣ
Answer:
f(x) = 5(1/5) ⁻ˣ
f(x) = 5(5)ˣ
89 x (100-2) = 98 x (100-x) What should replace 'x' to make the equation true?
Answer:
x=11
Step-by-step explanation:
the 100-2=98 so you would need the 98 times 89 on both sides or something that is equal
[tex]\bigstar\bf\:89\times (100-2)=98\times (100-x)[/tex]
[tex]:\implies\tt\:89\times 98=98\times (100-x)[/tex]
[tex]:\implies\tt\:100-x=\dfrac{89\times 98}{98}[/tex]
[tex]:\implies\tt\:100-x=89[/tex]
[tex]:\implies\tt\:x=100-89[/tex]
[tex]:\implies\boxed{\bf{\gray{x=11}}}[/tex]

Answer:
A. 41 ft / sec.
Step-by-step explanation:
28 miles per hour = 28/(60*60)
= 28 /3600 miles per second
= 28 * 5280 / 3600 feet per second
= 41 ft / sec.
Answer:
I am taking a guess so bare with me on here.
Step-by-step explanation:
first off: you want to look at each answer and think about how logical each one is. So you can cross out D. because it doesn't seem logical.
Second: Think about a car. when you are on the high way and your parents say 60 MPH that means going that speed (60MPH) you can get about 60 miles an hour and an hour is 60 min and 60 min is about 3,600 seconds because a min is 60 seconds.
Third: take out any other answer that looks too high or too low.
4th: the answer is A. because 88 and 189 is too high. and 36 is too low.

c. y=-2(x-3) 2+2
D. y = -2(x-3)2-2
Answer:
B.y=-2(x+3)2-2
Step-by-step explanation:
A if false beacuse you have to put (-3,-2) into all of your equations
B is correct
C is false
D is also false
A table has an area of 12 ft^2 and a perimeter of 16 ft. What are the dimensions of the table?
Answer:
2 and 6
Step-by-step explanation:
Well if the are is 12ft^2 and the perimeter is 16 ft then the length is 6 ft and the width is 2 ft.
So 6+6+2+2=16
6*2 is 12
Answer:
Step-by-step explanation:
hello,
we can assume that the table is a rectangle
so let's note x , y its length and width, we can write
(1 ) 2(x+y)=16
(2) xy=12
x and y are different from 0 and from (2) we can write
y =12/x we replace it in (1)
x+12/x=16/2=8
[tex]<=> x^2+12=8x\\<=> x^2-8x+12 = 0\\<=> x^2 -2x-6x+12=0\\<=> x(x-2)-6(x-2)=0\\<=> (x-6)(x-2)=0\\<=> x = 6 \ \ or \ \ x=2[/tex]
for x = 6 y = 2
for x = 2 y = 6
so the dimensions of the table is 2ft x 6ft
hope this helps

Answer:
-15,20
Step-by-step explanation:
I do not know how to explain how I did it lol :) , but I am very sure that it is correct.
I hope this help you :)
Answer:
-15, 20
Explanation:
To solve this problem we must first understand what the pattern is in the sequence. Once we understand the pattern, we can then apply it to the final known term to find the next two terms.
Take a look at the sequence given:
5, -5, 10, -10, 15,...
Let's start by figuring out how they got the second term in the sequence. To do that, identify what basic operation and number must be applied. This will reveal the pattern.
5 - first term
-5 - second term
5 ? ? = -5
5 × -1 = -5
So, this means the sequence multiplied negative one by the first term to get the second term. Therefore, the pattern should be 'multiply negative one' to get the next term. Just to be sure the pattern we found is correct, apply it to the given sequence.
5, -5, 10, -10, 15,...
5 × -1 = -5 [correct; provides the next term]
-5 × -1 = 5 [incorrect; does not provide the next term]
10 × -1 = -10 [correct; provides the next term]
-10 × -1 = 10 [incorrect; does not provide the next term]
According to the calculations shown above, the pattern we have identified ('multiply negative one') only works on every other term. Therefore, we must figure out the rest of the pattern for the remaining terms. To do that, identify what basic operation and number must be applied.
-5 - second term
10 - third term
-5 ? ? = 10
-5 × -2 = 10
So, this means the sequence multiplies negative two every other term. Therefore, the pattern should be:
multiply by negative one, multiply by negative two
However, to be sure the pattern we have identified is correct, apply it to the sequence.
5 × -1 = -5 [correct; provides the next term]
-5 × -2 = 10 [correct; provides the next term]
10 × -1 = -10 [correct; provides the next term]
-10 × -2 = 15 [correct; provides the next term]
Now that we have identified the correct pattern, let's apply it to the last term to find the next two terms.
5, -5, 10, -10, 15....
15 × -1 = -15
-15 × -2 = 20
Therefore, the next two terms in the sequence is -15, 20.
Which sets are best represented by the Venn diagram G = {odd numbers)
H = {even numbers)
1 = {prime numbers
B. G = {a,b,c}
H = {d, e, f}
1 = {a, d, g}
C. G= {1, 2, 3
H = {2, 4, 9}
1 = {4, 5, 6)
D. G={a, -13,7}
H={-13, -15, s}
1 = {s, a, 23}
Answer:
option C.
G = {1, 2, 3}
H = {2, 4, 9}
1 = {4, 5, 6}
Step-by-step explanation:
From the diagram given above, we obtained the following information:
1. G Intercession H (G n H) has members i.e (G n H) is not epmty
G n H ≠ empty.
2. H Intercession I (H n I) has members i.e (H n I) is not empty
H n I ≠ empty.
3. G Intercession I (G n I) is empty i.e
G n I = empty.
Please note: Intercession of sets talks about elements or members common to the sets.
With the above information, we can suggest the answer to the question as follow:
For option A:
G = {odd numbers} = {1, 3, 5, 7,.. }
H = {even numbers} = {2, 4, 6, 8,.. }
I = {prime numbers} = {2, 3, 5, 7,...}
Therefore:
G n H = {} = empty
H n I = {2}
G n I = {3, 5, 7,..}
For option B:
G = {a,b,c}
H = {d, e, f}
I = {a, d, g}
Therefore:
G n H = {} = empty
H n I = {d}
G n I = {a}
For option C:
G = {1, 2, 3}
H = {2, 4, 9}
I = {4, 5, 6}
Therefore:
G n H = {2}
H n I = {4}
G n I = {} = empty
For option D:
G = {a, -13, 7}
H = {-13, -15, s}
I = {s, a, 23}
Therefore:
G n H = {-13}
H n I = {s}
G n I = {a}
From the above illustrations, only option C is correct.
The radius of a circle is 4 feet. What is the area of a sector bounded by a 45° arc?
Answer:
[tex]Area = 6.28\ ft^2[/tex] or [tex]Area = 2 \pi\ ft^2[/tex]
Step-by-step explanation:
Given
[tex]Radius, r = 4ft[/tex]
[tex]Angle, \theta = 45[/tex]
Required
Calculate the area of the sector
When angle is given in degrees, the area of sector is calculated as thus;
[tex]Area = \frac{\theta}{360} * \pi * r^2[/tex]
[tex]Substitute\ r = 4\ and\ \theta = 45[/tex]
[tex]Area = \frac{\theta}{360} * \pi * r^2[/tex] becomes
[tex]Area = \frac{45}{360} * \pi * 4^2[/tex]
[tex]Area = \frac{45}{360} * \pi * 16[/tex]
[tex]Area = \frac{45*16}{360} * \pi[/tex]
[tex]Area = \frac{720}{360} * \pi[/tex]
[tex]Area = 2 * \pi[/tex]
[tex]Area = 2 \pi\ ft^2[/tex]
The above is the area in terms of π
Solving further.... (Take π as 3.14)
[tex]Area = 2 \pi\ ft^2[/tex] becomes
[tex]Area = 2 * 3.14\ ft^2[/tex]
[tex]Area = 6.28\ ft^2[/tex]
Hence, the area of the sector is
[tex]Area = 6.28\ ft^2[/tex] or [tex]Area = 2 \pi\ ft^2[/tex]
Reflecting the graph of y = sin x across the yaxis is the same as reflecting it
across the x-axis.
TRUE OR FALSE
Answer:
True
Step-by-step explanation:
Answer:
TRUE
Step-by-step explanation:
This is due to the symmetry of the sin function, which states that:
[tex]sin(-x)=-sin(x)[/tex]
Plotting both of these functions is a reflection of [tex]y=sin(x)[/tex] in both axis.
Compute i^1+i^2+i^3+...+ i^97 + i^98+i^99.
If [tex]i=\sqrt{-1}[/tex], then [tex]i^2=-1[/tex], [tex]i^3=-i[/tex], and [tex]i^4=1[/tex].
We can break up the given sum into 25 groups (after adding and subtracting [tex]i^{100}[/tex]):
[tex](i+i^2+i^3+i^4)+(i^5+i^6+i^7+i^8)+\cdots+(i^{97}+i^{98}+i^{99}+i^{100})-i^{100}[/tex]
We have
[tex]i+i^2+i^3+i^4=i-1-i+1=0[/tex]
and in each group, we can pull this out as a factor. For example,
[tex]i^{97}+i^{98}+i^{99}+i^{100}=i^{96}(i+i^2+i^3+i^4)=0[/tex]
So the entire sum reduces to the remaining term,
[tex]-i^{100}=-i^{25\cdot4}=-(i^4)^{25}=-1^{25}=\boxed{-1}[/tex]

Which right triangular prism has the greatest volume? A triangular prism. The triangular base has a base of 7 meters and height of 9 meters. The height of the prism is 6 meters. A triangular prism. The triangular base has a base of 6 meters and height of 13 meters. The height of the prism is 5 meters. A triangular prism. The triangular base has a base of 11 meters and height of 8 meters. The height of the prism is 8 meters. A triangular prism. The triangular base has a base of 10 meters and height of 9 meters. The height of the prism is 8 meters.
Answer: The correct answer is option 4;
A triangular prism. The triangular base has a base of 10 metres and a height of 9 metres. The height of the prism is 8 metres.
Step-by-step explanation: A simple check for the result of each set of dimensions would give the correct answer.
The volume of a right triangular prism is derived as follows;
Volume = 1/2 * b * h * l
Where, b is the base of the triangle, h is the vertical height of the triangle and l is the length of the prism.
Note that the area of the right triangle is denoted by 1/2 * b * h, and multiplying this result by the length of the prism gives the entire depth or volume of the triangular prism. Let us examine the dimensions one after the other;
(1) A triangular prism. The triangular base has a base of 7 metres and height of 9 metres. The height of the prism is 6 metres.
Volume = 1/2 * 7 * 9 * 6
Volume = 189 cubic metres
(2) A triangular prism. The triangular base has a base of 6 metres and height of 13 metres. The height of the prism is 5 metres.
Volume = 1/2 * 6 * 13 * 5
Volume = 165 cubic metres
(3) A triangular prism. The triangular base has a base of 11 metres and a height of 8 metres. The height of the prism is 8 metres.
Volume = 1/2 * 11 * 8 * 8
Volume = 352 cubic metres
(4) A triangular prism. The triangular base has a base of 10 metres and a height of 9 metres. The height of the prism is 8 metres.
Volume = 1/2 * 10 * 9 * 8
Volume = 360 cubic metres

Step-by-step explanation:
find a pattern: +3, -2
the missing numbers are 8 and 12
Answer:
The numbers missing are 8 and 7.
Step-by-step explanation:
First you need to find a pattern in the numbers. You will notice that the pattern is add 3, subtract two. This is because, to get from 4 to 7, you add three, and to get from 7 to 5, you subtract 2.
When you apply that pattern, you find the missing numbers.
5(+3)=8, then 8(-2)=6, then 6(+3)=9, then 9-2=7, then 7(+3)=10

A certain club has $50$ people, and $4$ members are running for president. Each club member votes for one of the $4$ candidates. How many different possible vote totals are there?
Answer:
The number of different possible vote totals is 184.
Step-by-step explanation:
It is provided that there are N = 50 people in a club.
The position of President is open. And there are x = 4 members running for he post of President.
So, there are n = N - x = 50 - 4 = 46 people voting for these 4 members.
Each member of the club has x = 4 possible choices.
So, the number of different possible vote totals are:
Number of different possible votes = n × x
= 46 × 4
= 184
Thus, the number of different possible vote totals is 184.
