the radius of each circle is 2mmworkout the exact area of the rectangle
give your answer in the form a√ 3+b
where a and b are integers
Answers
The area of the rectangle having three identical circles inside is calculated as: (16√3 + 32) mm².
What is the Area of a Rectangle?Area of rectangle = (length)(width)
The image of the three identical circles in the rectangle has been labelled as shown in the diagram attached below.
We need to find the measure of the length and width of the rectangle.
Radius = AB = BD = DF = FG = CD = HI = 2 mm
Length of the rectangle = AB + BD + DF + FG = 2 + 2 + 2 + 2
Length of the rectangle = 8 mm
Width of the rectangle = CD + DH + HI
CD = 2 mm
HI = 2 mm
Use the Pythagorean theorem to find the measure of DH
DH = √(FH² - DF²)
FH = 2 + 2 = 4 mm
DF = 2 mm
Substitute
DH = √(4² - 2²)
DH = √(16 - 4)
DH = √12 = 2√3 mm
Width of the rectangle = CD + DH + HI = 2 + 2√3 + 2
Width of the rectangle = 2√3 + 4
Area = (2√3 + 4)(8)
Area = (16√3 + 32) mm²

Write the ratio that compares the championships won by Australia to the total number of championships. Then explain it's meaning
Answers
The ratio that compares the championship won by Australia to the total number of championship is 6/41 which means that of the total 41 championship Australia has won 6 of the championship.
According to the question we have been given that,
Total number of championship = 41
Total number of championship won by Australia = 6
Thus we need to find the ratio that compares the championship won by Australia to the total number of championship.
For this the ratio will be : [tex]\frac{number of championship won by Australia}{Total number of championship }[/tex]

The domain of the function is [-2, 2] and the range of the function is [-1, 2].
If there is a function y = x + a, then the domain is the set of all values that x can take and the range is the set of all the values that y can take for the function to exist.
Here, we are given a function as shown in the graph.
As we can see the function is defined only for the given points, that is, it has 2 endpoints.
Just by looking at the graph we can see that x can take values from -2 to 2. Thus, the domain of the function is [-2, 2].

Based on the given task content, the approximate radius of the tan circle given the area of the blue circle is 9.27 yards.
Area of a circleArea of the tan circle = xArea of the blue circle = (5x - 15) Area of blue circle = 1,335 square yards1,335 = 5x - 15
Add 15 to both sides1,335 + 15 = 5x
1,350 = 5x
divide both sides by 5x = 1350/5
x = 270 square yards
Area of the tan circle = πr²
270 = 3.14 × r²
270 = 3.14r²

Answers
The range of the function f(x) = 2.250x is 22.5 <= f(x) <= 36
What is the range of a function?The range of a function is the set of output values of the graph.
This in other words mean the range of a function is the set of y values of the graph.
How to determine the range of the function?The function is given as
f(x) = 2.250x
Where there are at least 10 but no more than 16 players on the baseball team
This means that the domain of the function is
10 <= x <= 16
Substitute the domain values in the given function
So, we have
f(x) = 2.250x
f(10) = 2.250 * 10
Evaluate
f(10) = 22.5
f(x) = 2.250x
f(16) = 2.250 * 16
Evaluate
f(16) = 36
The range of the function is then represented as
f(10) <= f(x) <= f(16)
So, we have
22.5 <= f(x) <= 36
Hence, the range of the function f(x) = 2.250x is 22.5 <= f(x) <= 36

How much should you invest in an account that pays 6 % annual interest compounded continuously if you want exactly $ 8000 after four years? Show your work.
Answers
We must invest $6294.256 if we want exactly $ 8000 after four years.
The formula for calculating the amount (A) on a principal (P) invested at the rate of r%, compounded continuously, after t years is-
[tex]A = Pe^{rt}[/tex]
Here, we are given that rate of interest = 6% and we need exactly $8000 after four years.
Thus r = 6/100 = 0.06 and t = 4
Putting the values in the compound interest formula we get,
8000 = P[tex]e^{(0.06*4)}[/tex]
8000 = P[tex]e^{(0.24)}[/tex]
P[tex]e^{(0.24)}[/tex] = 8000
[tex]e^{(0.24)}[/tex] = 1.271
⇒ 1.271P = 8000P
= 8000/ 1.271P
= 6294.256
Thus, we must invest $6294.256 if we want exactly $ 8000 after four years.

Common logarithms are based on the number 10, while natural logarithms are based on the base "e."

Answers
The inequality comparing the elevations is -220 > -282 and -220 feet is closer to sea level.
The elevation of Bad Water Basin = -282 feet
The elevation of the Salt Creek = -220 feet
We are asked to compare the elevations and find which is greater than the other.
So we know that on a number line -220 is greater than -282.
This can be understood in the same sense that -1 > -2 on the number line.
So the inequality comparing the elevations is -220 > -282.
Now consider the sea level as 0 on the number line.
Then clearly -220 is closer to 0 on number line.
Hence the elevation closer to the sea level = -220 feet.
