Answer:C=2πA=2·π·1≈3.54491
Step-by-step explanation:
Answer:
119.32
Step-by-step explanation:
The formula for the area of a circle is:
A = πr², where π = 3.14 and r = radius
The formula for the circumference of a circle is:
C = 2πr, where π = 3.14 and r = radius
So, in order to solve for circumference, you need to solve for 'r'. Using the formula for area:
1134.11 = πr²
Divide by π (3.14): 1134.11/3.14 = πr²/3.14 or 361.2 = r²
Take the square root of both sides: √361.2 = √r² or r≈19
Use the value of r = 19 to solve for circumference:
C = 2π(19) = 2(3.14)(19) = 119.32 meters

Question 3 V (t) 30(1.05), where t is the time, in years, since opening the account Connie deposits $30 into an account. The value of the account, in dollars, can be modeled as To the nearest cent, what is the average rate of change in the value of the account for the first 3 years? A $0.63/year B $1.58/year С $3.15/year thing D $4.73/year
Answer:
b
Step-by-step explanation:
The average rate of change in the value of the account for the first 3 years is, $3.15/year. So Option C is correct.
What is the rate?Rate is a ratio of change in one quantity w.r.t. change in another quantity. The net change in one quantity is written as, Δy and the net change in another quantity is written as, Δx.
So formula for the rate is,
m = change in one quantity/change in another quantity = Δy/Δx
The average rate of change in the value of the account for the first 3 years can be calculated as follows:
Let t = 0 be the time when the account is opened,
and t = 3 be the end of the third year.
The value of the account at t = 0 is V(0) = 30,
and the value of the account at t = 3 is
V(3) = 30(1.05)³
The average rate of change in the value of the account over the first 3 years is given by the formula:
⇒ (V(3) - V(0)) / (3 - 0)
⇒ (30(1.05)³ - 30) / 3
⇒ $3.15/year
Hence, the average rate of change in the value of the account over the first 3 years is approximately $3.15/year

How much sand do you need to add to 3.2m^3 of soil with 40% sand in order to make a soil with 60% sand
Answer:
[tex]1.6m^3[/tex] sand is to be added to make sand percentage [tex]60\%[/tex]
Step-by-step explanation:
From the question we are told that:
Total soil [tex]N=3.2m^3[/tex]
Initial sand percentage [tex]S_1=40\%[/tex]
Final sand percentage[tex]s_2=60\%[/tex]
Generally the sand and other particles division is mathematically given by
[tex]40\% of 3,2=1.28[/tex]
and
[tex]60\% of 3.2=1.92[/tex]
Generally what will make 60\% of 3.2 40\% is mathematically given by
[tex]x=1.92*0.4\\x=4.8[/tex]
Generally the sand to be added is mathematically given by
[tex]4.8sand-3.2sand =1.6m^3[/tex]
Therefore
[tex]1.6m^3[/tex] sand is to be added to make sand percentage [tex]60\%[/tex]

What is Transformation?A transformation is a broad phrase covering four distinct methods of changing the shape and/or position of a point, line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
When we scale a triangle by some factor, neither its shape nor size change. The image corresponds to the previous image.
The horizontal translation of x coordinate is either horizontally right or horizontally left depending on the positive or negative value of x - coordinate.
Depending on the positive or negative value of the y - coordinate, the y coordinate is translated vertically up or down.
Here (8 ,4) shows there is shifting Horizontally right (x+ 8) and there is shifting Vertically up (y + 4).

I don't understand this my teacher is not texting me back
Answer:
Please find below. Fill in the table with the values of y given below.
Step-by-step explanation:
For question 5, you should substitute the different values of x into the equation y =x^2 +4
So, when
x = -3, y = (-3)^2 +4 = 9+4 = 13
x = -2, y = (-2)^2 +4 = 4+4 = 8
x = -1, y = (-1)^2 + 4 = 1+4 = 5
x = 0, y = 0^2 + 4 = 4
x = 1, y = 1^2 +4 = 1+4 = 5
x = 2, y = 2^2 +4 = 8
x = 3, y = 3^2 + 4 = 13
x = 4, y = 4^2 + 4 = 20
For question 6, you need to find the nth term or a formula of y in terms of x.
For this, find the common difference between each of the consecutive values of y.
This is 5
So, the start if our equation is going to be ‘y = 5x’
Now, to find the ‘+c’ part, can be calculated by substituting the value of y when x = 1 into the y = 5x
So,
y = 5x + c
13 = 5 + c
Rearrange the find that c = 8
Therefore, the nth term formula = 5x + 8

Which city had a lower median temperature?
Hooverville

Answer:
Hooverville
Step-by-step explanation:
The Hooverville has lower median temperature.
What is Box and Whisker Plot?A box and whisker plot is a method for abstracting a set of estimated data using an interval scale. Another name for it is simply a box plot. Most of the time, these are used to interpret data. It is one kind of graphical method that shows how the data in the dataset changes. The histogram can also be used to show the data. However, the histogram provides an adequate display. Since multiple sets of data can be displayed in the same graph, a box and whisker diagram will provide additional information, making it superior to a histogram.
Given Box and Whisker Plot of two cities which show's the noon temperature each day,
From the graph Median of Hooverville is 36 and
median of Deeson City is 38
we can say that Hooverville has lower median temperature.
Hence the lower median temperature is of Hooverville.
