The equation 1/2r = π/CB is true. Choose the second option

The circumference of a circle is the distance around the circle, or the length of the perimeter of the circle. It is given by the formula:

circumference = 2πr = πd

where r is the radius and d is the diameter

Note: d = 2r

Given: d2 = 2r and CB denotes the circumference of ⨀B

CB =  πd2  

CB =  2πr   (d2 = 2r)

Divide both sides by CB:

CB/CB =  2πr/CB

1 = 2πr/CB

Divide both sides by 2r:

1/2r = 2πr/2rCB

1/2r = π/CB

Thus, the second equation is true

Answer:

To compare the length of the plankton to the length of the jellyfish, we can express the length of the plankton as a percentage of the length of the jellyfish.

First, we need to convert the length of the jellyfish from inches to centimeters so that we can compare the two measurements in the same unit.

12 inches = 12*2.54 = 30.48 cm

Next, we divide the length of the plankton by the length of the jellyfish and multiply by 100 to get the percentage.

0.08 inches / 30.48 cm * 100 = 0.00262 * 100 = 0.262%

So, the length of the plankton is 0.262% of the length of the jellyfish.

3.64 x [tex]10^8[/tex] divided by 3.3 x [tex]10^4[/tex] is equal to 110.12121212121212.

The division is an arithmetic operation that is the inverse of multiplication. It involves splitting a quantity into a number of equal parts. The symbol for division is typically a forward slash (/) or a horizontal line. For example, if you have 10 apples and you want to divide them equally among 5 people, each person would receive 2 apples (10 ÷ 5 = 2). The result of division is called the quotient.

Here is one way to divide 3.64 x 10^8 by 3.3 x 10^4 step by step:

Write the numbers as decimal numbers: 3.64 x 10^8 is equal to 364000000 and 3.3 x 10^4 is equal to 33000.

Divide the decimal numbers: 364000000 ÷ 33000 = 11006.06

The result is 11006.06.

The measure of ∠A is 123 degrees.

The angle made between the radius and the tangent at the point of contact on a circle is 90°.  

Therefore,

∠D = 90 degrees

∠E = 90 degrees

The diagram ACDE forms a quadrilateral. The sum of angles in a quadrilateral is 360 degrees.  Therefore, we have to equate the sum of the quadrilateral angles to 360 degrees.

Hence,

90 + 90 + 2x + 7 + 5x - 2 = 360

180 + 7x + 5 = 360

7x = 360 - 180 - 5

7x = 180 - 5

7x = 175

x = 175 / 7

x = 25

Therefore,

Next, we need to find the number of students that are in favor of forming a track team: 3/5 of the freshmen are in favor = 3/5 * 1050 = 630 students

To find the number of non-freshmen students: 3400 students - 1050 students = 2350 students

Now we need to find the number of non-freshmen students in favor of forming a track team: 1/5 of the non-freshmen students are in favor = 1/5 * 2350 = 470 students

Finally, to find the number of students opposed to the idea we need to subtract the number of students in favor from the total number of students: 3400 students - (630 students + 470 students) = 3400 - 1100 = 2300 students

Answer:

$25,900 initially

$8,128 after 11 years

Step-by-step explanation:

One thing to note, is I'm assuming you meant: [tex]v(t)=25,900(0.90)^t[/tex] and not  [tex]v(t)=25,900(0.90)^2[/tex], otherwise that would just be a constant function and not an exponential function.

There are a couple key features of exponential functions we can derive from simply analyzing the equation.

For now I will be using the form: [tex]y=a(b)^x\text{ where b} > 0, \text{b}\ne 1[/tex]

The y-intercept, is just the "a" value, which is because the y-intercept is simply when x=0, and if we raise a number to the power of zero, we get one (excluding zero as a base), so we get the form: [tex]y=a[/tex], so "a" is our y-intercept.

there's actually two type of exponential functions: exponential growth and exponential decay.

Exponential Decay:

Exponential decay, as the name implies, is when a function is decaying or decreasing. This occurs when [tex]0 < b < 1[/tex].

The decay rate can be represented as "r" in decimal form, where: [tex]b=1-r[/tex].

The reason for this is because "1" can be thought of as 100% and "r" is r%, so you're taking away r% or decaying the value by r%, also known as a decay rate.

Exponential Growth:

Exponential growth as the name implies, is when a function is growing or increasing. This occurs when b > 1

The growth rate can be represented as "r" in decimal form where: [tex]b=1+r[/tex]

The reason for this is similar to decay rate except instead of taking away r% or decaying, it's "giving r%" or growing.

The question doesn't actually require finding exponential growth or decay, but it's still an important key feature.

In this case, we really just need to find the y-intercept and plug in t=11.

The y-intercept in many graphs, not just exponential graphs, represents some sort of initial value, which in this case, is the initial value of the car. As stated above, this y-intercept is just the value in front, which is 25,900.

As for the value after 11 years, we simply need to plug in t=11 to get the following: [tex]v(11)=25,900(0.90)^{11}[/tex], from here we can use a calculator to simplify this: [tex]v(11)\approx25,900(0.31381059609)\approx 8,127.694438731[/tex], which rounds to 8,128
