Answer: a.) Circle B
b.) 9.42
Step-by-step explanation:
A diameter of 9 cm means that the circumference of Circle A is approximately 28.26 cm.
Circumference = Diameter x π
9 x 3.14 = 28.26
A radius of 6 cm means the circumference of Circle B is approximately 37.68 cm.
Circumference = 2 x Radius x π
2 x 6 x 3.14 = 37.68
37.68 > 28.26
37.68 - 28.26

Answer:
x = 14
Step-by-step explanation:
First step is to set the opposite sites equal to each other (they are congruent)
13 = 2y + 1
and
x = y + 8
Now solve for y in terms of x so you can substitute it in the other equation
x - 8 = y
Plug into equation
13 = 2(x-8) + 1
13 = 2x - 16 + 1 distribute
13 = 2x - 15 simplify
28 = 2x add 15 to both sides
x = 14

a box contains 6 red, 8 green, 10 blue, 12 yellow and 15 white balls. what is the minimum number of balls we have to choose randomly from the box to ensure that we get 9 balls of same color?
Answers
The minimum number of balls that must be chosen randomly from the box to ensure that we get 9 balls of the same color is 39.
Given that a box contains 6 red, 8 green, 10 blue, 12 yellow, and 15 white balls.
As the question says that the minimum number of balls chosen must ensure that we get 9 balls of the same color, so we must consider the balls of those colors which are more than 9 in number.
Here, 10 blue, 12 yellow, and 15 white balls are considered as they are more than 9.
By applying the Pigeon principle,
we can get.,
9 blue + 9 yellow + 9 white – 3 + 1 = 25
As we are picking randomly so we can get all the red and green balls before the above 25 balls.
Therefore we add the balls 6 red + 8 green + 25 = 39
Hence, the minimum number of balls that must be chosen randomly from the box to ensure that we get 9 balls of the same color is 39.

what is the total area of the shaded sections of trapezoid?
Answers
The shaded sections of the trapezoid are triangles.
We know how to find the area of triangles
A = 1/2 bh
Lets start with the left triangle
The bases is 1.1 inches and the height is 3.8 inches
A left triangle is
A = 1/2 ( 1.1) * 3.8 = 2.09
The right triangle has the same dimensions
A right triangle is
A = 1/2 ( 1.1) * 3.8 = 2.09
Add the two triangles together
2.09+2.09 = 4.18 in^2
The area of the shaded region is 4.18 in^2

Calculate the area of triangle ABC
Answers
The area of the triangle is 18 cm.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
In Triangle ABC,
AB= 6cm
AC= 8cm
BC= 12cm.
Angle ACB= 26.4
The area of a triangle is given as:
Area = 1/2 x base x height
From the figure below,
Base = BC = 12
D is the midpoint of BC.
BC = BD + DC
DC = 12/2 = 6
Height = Tan 26.4
Tan 26.4 = AD / DC = AD / 6
0.50 = AD / 6
AD = 0.50 x 6
AD = 3
Now,
Area of the triangle ABC:
= 1/2 x base x height
= 1/2 x 12 x 3
= 18 cm
Thus,

A loan of $50,000 is taken out for six years at 9% interest compounded annually. If the loan is paid off in full at the end of that time period, $50433 must be returned.
What is Compound interest?Compound interest is calculated by multiplying the initial loan amount, or principal, by one plus the annual interest rate multiplied by the number of compound periods multiplied by one. Compound interest is when you earn interest on both your savings and your interest earnings. When you compound interest, you add the interest you've earned back into your principal balance, which earns you even more interest, compounding your returns. Assume you have $1,000 in a savings account earning 5% interest per year. You'd earn $50 in year one, giving you a new balance of $1,050. Compound interest occurs when interest earned on savings begins to earn interest on itself.

Answers
The end behavior of the graphs of the functions f(x) and g(x) are common.
Consider the two functions,
f(x) = x³ + x² - 6x and g(x) = [tex]e^{x+2}[/tex] - 1
Now,
y = x³ + x² - 6x
The x-intercept will be:
0 = x³ + x² - 6x
x( x² + x - 6 ) = 0
x( x - 2 )( x + 3 ) = 0
So, x = 0, 2, - 3
Hence, the x-intercepts are ( 0, 0 ), ( 2, 0 ), and ( - 3, 0 ).
The y-intercept will be:
y = x³ + x² - 6x
y = (0)³ + (0)² - 6(0)
y = 0
Hence, the y-intercept is ( 0, 0 ).
The range of the function f(x) = x³ + x² - 6x is ( - ∞, ∞ ).
Using the degree 3 and the leading coefficient 1 of the function f(x) the end behavior of the function will be:
Falls to the left and rises to the right.
For the function,
y = g(x) = [tex]e^{x+2}[/tex] - 1
The x-intercept will be:
y = [tex]e^{x+2}[/tex] - 1
0 = [tex]e^{x+2}[/tex] - 1
[tex]e^{x+2}[/tex] = 1
[tex]e^{x+2}[/tex] = e⁰
x + 2 = 0
x = - 2
Hence, the x intercept is ( - 2, 0 ).
The y-intercept will be:
y = g(x) = [tex]e^{x+2}[/tex] - 1
y = e² - 1
Hence, the y-intercept will be ( 0, e² - 1 ).
The range of the function g(x) is ( - 1, ∞ ).
The end behavior of the function g(x) constantly rises to the right in the positive y-axis.
Hence, the functions f(x) and g(x) have the end behavior in common.
