Answer:
d = 52 inC = 6π mm²Step-by-step explanation:
The formula of a circumference:
[tex]C=2\pi r=d\pi[/tex]
r - radius
d - diameter
We have [tex]C=52\pi\ in[/tex].
Calculate the diameter using [tex]C=d\pi[/tex]:
[tex]d\pi=52\pi[/tex] divide both sides by π
[tex]d=52\ in[/tex]
-------------------------------------------------------------------------
If a circle inscribed in a square, then the diameter of a circle and a side of a square are congruent (have the same length).
We have the area of the square:
[tex]A=36\ mm^2[/tex]
The formula of an area of a square:
[tex]A=s^2[/tex]
s - side
Substitute:
[tex]s^2=36\to s=\sqrt{36}\\\\s=6\ mm[/tex]
The formula of a circumference [tex]C=d\pi[/tex]
d - diameter
d = s → d = 6 mm
Substitute:
[tex]C=6\pi\ mm[/tex]

QUESTION 6
The growth of a population each year is given by the function f(x)=250,000(1.17)* At what percent is the population growing each year?
A. 250,000%
B. 1.17%
C. 292,500%
D. 17%
Answer:
Option D. 17%
Step-by-step explanation:
we have
[tex]f(x)=250,000(1.17)^{x}[/tex]
This is a exponential function of the form
[tex]f(x)=a(b)^{x}[/tex]
where
a is the initial value
b is the base
In this problem
a=250,000 people
b=1.17
Remember that
b=1+r
so
1+r=1.17
r=1.17-1=0.17
Convert to percentage
0.17*100=17%

B. 37; 20; 17.6
C. 37; 17.6; 20
D. 13; 17.6; 21
Answer:
cdc
Step-by-step explanation:
1. The option is (A) mean = –25; median = –26.5; mode = –28; range = 40.
2. The option is (C) 13; 17.6; 20.
What is the median?The median is the value that splits the mathematical numbers or expressions in the half. The median value is the middle number of data points. to find the median first arrange the data points in ascending order.
To find the mean, median, mode, and range of the data set, we first need to arrange the data in order:
–46, –39, –28, –28, –25, –17, –11, –6
Mean: To find the mean, we add up all the values and divide by the total number of values:
Mean = (-46 + -39 + -28 + -28 + -25 + -17 + -11 + -6) / 8
Mean = -25
Median: To find the median, we need to find the middle value of the data set.
Since there are 8 values, the median is the average of the 4th and 5th values:
Median = (-28 + -25) / 2
Median = -26.5
Mode: The mode is the value that appears most frequently in the data set. In this case, the mode is –28, since it appears twice and no other value appears more than once.
Range: To find the range, we subtract the smallest value from the largest value:
Range = -6 - (-46)
Range = 40
Therefore, the answer is (A) mean = –25; median = –26.5; mode = –28; range = 40.
2.
A. The outlier in the data set is 37, since it is much larger than the other values.
B. To find the mean with the outlier, we add up all the values and divide by the total number of values:
Mean = (21 + 13 + 13 + 37 + 13 + 23 + 25 + 15) / 8
Mean = 17.6
C. To find the mean without the outlier, we need to exclude the value 37 and then calculate the mean using the remaining values:
Mean = (21 + 13 + 13 + 13 + 23 + 25 + 15) / 7
Mean = 17.6
Therefore, the answer is (C) 13; 17.6; 20.

domain: {x | x is a real number}; range: {y | y > 2}
Step-by-step explanation:
We have the function [tex]f(x) =(\frac{1}{6})^x + 2[/tex]
Note that f(x) is an exponential function.
By definition the exponential functions of the form [tex]a(b)^x +k[/tex] have as domain all real numbers and as range {y | y > k} if [tex]a>0[/tex], [tex]b>0[/tex]
Where a is the main coefficient, b is the base and k is the vertical displacement.

A flagpole broke in a storm. 777 meters are still sticking straight out of the ground, where it snapped, but the remaining piece has hinged over and touches the ground at a point 242424 meters away horizontally.
How tall was the flagpole before it broke?
The broken flagpole forms a right triangle, where the vertical leg is the piece still standing and the hypotenuse is the broken piece.
So, the original length is the sum of the hypotenuse and the vertical leg.
The hypotenuse can be found using the pythagorean theorem:
[tex]h=\sqrt{7^2+24^2}=25[/tex]
So, the flag was originally [tex]7+25=32[/tex] meters long.

two circles have the same center one circle has the radius of 3 centimeters and the orner has a radius of 1 centimeter what is the locus of the points equidistant from the two circles?
Answer:
Step-by-step explanation:
It has to be another circle with its center as the same center as the other two.
It must be equadistant from both.
The circle must have a radius of 2 which makes it one away from the 3 cm circle and 1 away from the 1 cm circle.
A bookstore receives a shipment consisting of two boxes. There is no empty space in either of the boxes. The first box contains 16 books, each measuring 3/2 in by 8 in by 11 in. The second box contains 30 books, each measuring 3/4 in by 5 in by 8 in.
Explain which of the two boxes is larger and how you know. Show your work to support your explanation.
To find the answer, I used:
Volume = Length • Height • Width
Each book in box 1 has a volume of 132 inches^3 and there are 16 of them, so I multiplied 132 inches^3 by 16 and got a total volume of 2,112 inches^3 in box 1
Each book in box 2 has a volume of 30 inches^3 and there are 30 of them, so I multiplied 30 inches^3 by 30 and got a total volume of 900 inches^3 in box 2
2,112 inches^3 is greater than 900 inches^3 so box 1 should be more than twice as big as box 2
2112 cubic inches.
To determine which of the two boxes is larger, we need to calculate the volume of each box. For the first box, containing books each measuring 3/2 in by 8 in by 11 in, the volume of one book is calculated as:
Volume of one book = (3/2) * 8 * 11 = 12 * 11 = 132 cubic inches.Total volume for 16 books = 132 * 16 = 2112 cubic inches.For the second box, containing books each measuring 3/4 in by 5 in by 8 in, the volume of one book is calculated as:
Volume of one book = (3/4) * 5 * 8 = 3.75 * 40 = 150 cubic inches.Total volume for 30 books = 150 * 30 = 4500 cubic inches.Comparing the two totals, the second box, with a total volume of 4500 cubic inches, is larger than the first box, which has a total volume of 2112 cubic inches. Hence, we know that the second box is larger because it has a greater total volume.

A basketball is thrown upwards. The height f(t), in feet, of the basketball at time t, in seconds, is given by the following function:
f(t) = −16t2 + 94t + 12
Which of the following is a reasonable domain of the graph of the function when the basketball falls from its maximum height to the ground?
2.9375 < t < 6
2 < t < 5
1 < t < 4
0 < t < 3
Answer:
Well I think it is A because domain is the x values.
Step-by-step explanation:
So when you plug this in your calculator (mine is a ti-84 plus ce) you would hit graph. After it graphs it press Zoom, 0 to center it then press 2nd, trace which pulls up parabola menu's. Press 0 and find the left bound, right bound and then press enter which would give you x values of 2.9375 < t< 6
At the same time I don't know if this is right. I never really excelled at parabolas just trying to help.
Check the picture below.
so the domain will be the values that "x" gets, now, the maximum height of the ball is when it reaches the vertex or U-turn up above, well, what is the x-coordinate anyway?
[tex]\bf \textit{vertex of a vertical parabola, using coefficients} \\\\ f(t)=\stackrel{\stackrel{a}{\downarrow }}{-16}t^2\stackrel{\stackrel{b}{\downarrow }}{+94}t\stackrel{\stackrel{c}{\downarrow }}{+12} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right) \\\\\\ \left( -\cfrac{94}{2(-16),}\qquad \qquad \right)\implies \left( \cfrac{487}{16},\qquad \qquad \right)\implies (2.9375,\qquad \qquad )[/tex]
so then x = 2.9375 at the vertex, now, what is "x" when it hits the ground? recall y = 0 at that instant.
[tex]\bf \stackrel{f(t)}{0}=-16t^2+94t+12\implies 0=-2(8t^2-47t-6) \\\\\\ 0=(8t+1)(t-6)\implies t= \begin{cases} \boxed{6}\\ \begin{matrix} -\frac{1}{8} \\[-0.5em]\cline{1-1}\\[-5pt]\end{matrix} \end{cases}[/tex]
so then, the values for "x" or namely the domain from the vertex till the ball hits the ground is 2.9375 < t < 6.

| What is the factored form of 2x2 – 200 ?
Answer:
2(x - 10)(x + 10)
Step-by-step explanation:
Given
2x² - 200 ← factor out 2 from each term
= 2(x² - 100) ← x² - 100 is a difference of squares and factors as
x² - 100 = x² - 10² = (x - 10)(x + 10), hence
2x² - 200 = 2(x - 10)(x + 10)
Answer:
Step-by-step explanation:
If your equation is [tex]2x^2-200[/tex] and you're to factor it, the first thing you do is set the expression equal to 0 so you can solve for x.
[tex]2x^2-200=0[/tex]
There's a couple of different ways in which to approach this. You can factor out a 2:
[tex]2(x^2-100)=0[/tex]
and solve it from there. The Zero Product Property says that if the equation is equal to 0, then either 2 has to equal 0 or [tex]x^2-100[/tex] has to equal 0. We know that 2 does not equal 0, so [tex]x^2-100=0[/tex]
Add 100 to both sides in the equation:
[tex]x^2=100[/tex]
and then take the square root of both sides. Because this is a second degree polynomial, we expect to have 2 solutions, and we do. Don't forget that when you take the square root of a number you have to alow for both the positive and the negative of the result. Our factored form of the given equation then is that x = 10 and x = -10.

Answer:
There will be approx 283908 hits.
Step-by-step explanation:
A website had 342,000 hits in 2011.
This is a decline of 2.3% from the previous year.
Decline rate = 2.3% or 0.023
So, increase rate will be [tex]1-.023=0.977[/tex]
Time = [tex]2019-2011=8[/tex]
We can calculate the answer as:
[tex]342000\times(0.977)^{8}[/tex]

This question is based on the Least Common Multiple (LCM) method. We will find the LCM of the numbers 4, 6 and 8.
4 = 2 x 2 = [tex]2^{2}[/tex]
6 = 2 x 3 = 2 x 3
8 = 2 x 2 x 2 = [tex]2^{3}[/tex]
So, LCM is = [tex]2^{3}\times3=24[/tex]
Therefore, at every 24th houses, we will find all three trolls colors.
And 24 is the number of houses we will find all color trolls. Then in a group of 75 houses, it will occur thrice and at every 24th place. Means. 3 houses will have all color trolls.
What is the solution to the system of equations below?
y= 4x+6 and Y= 2x-4
0 (-8, 2)
(-8,-1)
(8, 10)
(8, -10
The solution to the system of equations y=4x+6 and y=2x-4 is (-5, -14) by solving the equations simultaneously.
Explanation:The solution to the system of equations y = 4x + 6 and y = 2x - 4 is found by setting the two equations equal to each other since they both equal y. This gives us 4x + 6 = 2x - 4. By subtracting 2x from both sides, we get 2x + 6 = -4. Subtracting 6 from both sides gives us 2x = -10. Dividing both sides by 2 gives us x = -5. Substitute x = -5 into either original equation to find y. Let's use the first equation: y = 4(-5) + 6, which simplifies to y = -20 + 6, and finally y = -14. Hence, the solution to the system of equations is (-5, -14).

Explain how you know. (c) What do the answers to Parts 2(a) and 2(b) tell you about Colin’s and Jezebel’s sold games?
Answer:
a) The sold games of Jezebel had the greatest spread.
b) The middle 50% of the games sold by Colin has the least spread.
c) Jezebel sold more games than colin.
Step-by-step explanation:
Range is sued to calculate the spread of the given data.
Range is given by:
[tex]Range=Max\ Value-Min\ Value[/tex]
So,
Part a)
For Collin:
Range=21-3=18
For Jezebel:
Range=26-5=21
Part b)
Middle 50% of the values will be the values between 1st quartile and 3rd quartile
So, to find quartiles:
For Colin:
=3,9,9,14,15,16,17,20,21
The median is 15.
The lower half is 3,9,9,14
Q1 = (9+9)/2= 18/2 = 9
The upper half is 16,17,20,21
Q3 = (17+20)/2= 37/2= 18.5
The middle 50% is first quartile subtracted from third quartile
So, the spread is:
18.5-9=9.5
For Jezebel:
4,5,8,10,11,14,20,20,26
The median is 11.
The lower half is 4,5,8,10
Q1 = (5+8)/2=13/2=6.5
The upper half is 14,20,20,26
Q3 = (20+20)/2=40/2=20
The middle 50% values' spread is:
20-6.5=13.5

find the equation!!! asap. 10 points
Answer:
[tex]y=\frac{1}{60}x^2[/tex]
Step-by-step explanation:
The focus of the parabola is (0,15)
and the directrix is y=-15.
The equation of this parabola is given by:
[tex]x^2=4py[/tex]
The vertex of this parabola is at the origin (0,0)
The value of p is the distance from the vertex to the focus.
p=15-0=15
The equation of the parabola is
[tex]x^2=4(15)y[/tex]
[tex]x^2=60y[/tex]
Or
[tex]y=\frac{1}{60}x^2[/tex]
find the midpoint of the line segment with the given endpoints.
(14, -6), (13, 14)
Answer:
Step-by-step explanation:
23
Answer:
([tex]\frac{27}{2}[/tex], 4 )
Step-by-step explanation:
Use the midpoint formula
midpoint = [[tex]\frac{1}{2}[/tex](x₁ + x₂), [tex]\frac{1}{2}[/tex](y₁ + y₂ ) ]
with (x₁, y₁ ) = (14, - 6) and (x₂, y₂ ) = (13, 14), hence
[[tex]\frac{1}{2}[/tex](14 + 13), [tex]\frac{1}{2}[/tex](- 6 + 14) ]
= ([tex]\frac{27}{2}[/tex], 4)
Help! What is the probability that a card drawn from a standard 52 card deck is a diamond or a three?
Answer:6.5%
Step-by-step explanation:
There are 4, number three cards and 4 diamond cards in a deck of 52 cards. Divide 52 by 8.
Answer:
30.8% or 4/13
Step-by-step explanation:
There are 52 cards in a deck of cards.
There are 4 nines (4/52) and 13 (13/52) diamonds in a deck of cards.
When you add them together, you get 17/52. Then, you have to subtract the card that is both a nine and in a diamond suite, so you subtract -1 because there is only one card that fits both categories. You should have 16/52, which simplifies to 4/13 / 30.8%.

Let a,b & c be the number of cookies Adrian, Bobby and Calvin baked respectively.
(a+b+c)/3 =138
(a+b)/2 =136
a+b=272
a=272-b
(b+c)/2 =125
b+c=250
c=250-b
Sub a=272-b and c=250-b into (a+b+c)/3 =138,
(a+b+c)/3 =138
[(272-b)+b+(250-b)]/3 = 138
272-b+b+250-b = 414
-b = -108
b=108
From the above,
a=272-b
=272-108
a=164
c=250-b
=250-108
c=142
∵ a=164
b=108
c=142
∴ Adrian baked 164 cookies.
Bobby baked 108 cookies.
Calvin baked 142 cookies.
Rhombus LMNO is shown with its diagonals.
Angle MNO measures 112°. What is the measure of angle LMN?
34°
45°
56°
68°
Answer:
The measure of angle LMN is 68° ⇒ the last answer
Step-by-step explanation:
* Lets revise the properties of the rhombus
- The rhombus has 4 equal sides in length
- Every two opposite angles are equal in measure
- Every two adjacent angles are supplementary (their sum = 180°)
- The two diagonals bisect each other
- The two diagonals perpendicular to each other
- The two diagonals bisect the vertices angles
* Lets solve the problem
∵ LMNO is a rhombus
∴ ∠LMN and ∠MNO are adjacent angles
∴ ∠LMN and ∠MNO are supplementary
∴ m∠LMN + ∠MNO = 180°
∵ m∠MNO = 112°
∴ m∠LMN + 112° = 180° ⇒ subtract 112 from both sides
∴ m∠LMN = 68°
* The measure of angle LMN is 68°
Answer:
68
