The arc angle AC is measured as 55 degrees.
How to find arc angle?If two secant intersect in the exterior of a circle, then the measure of the angle formed is half the positive difference of the arcs intercepted.
Therefore, the secants intersect outside the circle at point E.
The arc angle AC can be found as follows:
Therefore,
m∠BED = 1 / 2 (arc angle AC - arc angle BD)
arc angle AC = x
arc angle BD = 23 degrees.
m∠BED = 16 degrees.
m∠BED = 1 / 2 (arc angle AC - arc angle BD)
16 = 1 / 2 (x - 23)
16 = 1 / 2x - 23 / 2
16 + 11.5 = 0.5x
27.5 = 0.5x
x = 27.5 / 0.5
x = 55 degrees.
Therefore,
arc angle AC = 55 degrees.

Suppose that $25,200 is invested in a certificate of deposit for 2 years at 11.1 % annual interest to be compounded semi-
annually. How much interest will this investment earn?
Suppose that $25,200 is invested in a certificate of deposit for 2 years at 11.1 % annual interest to be compounded semi-annually, compound interest will this investment earn is $5,904.8892.
What is compound interest?Compound interest, also known as interest on the principal and interest, is the practice of adding interest to the principal amount of a loan or deposit. It occurs when interest is reinvested, or added to loaned capital rather than paid out, or when the borrower is required to pay it, so that interest is generated the next period on principal amount plus any accumulated interest. In the finance and economics, compound interest is common.
In contrast to the simple interest, which does not compound since past interest is not added to the principal for the current period, compound interest allows interest to build over time. The interest per period multiplied by number of periods in a year yields the simple annual interest rate. The nominal interest rate is the another term for the basic annual interest rate (not to be confused with the interest rate not adjusted for inflation, which goes by the same name).
It is known that the compound interest is given as
Compound Interest = [total amount of the principal and interest in future]-[total amount of the principal in present]
=[tex]P(1+i)^{2} - P\\P(1+i)^{2} - 1\\[/tex]
where, p= principal, i= nominal annual interest, n= the number of the compounding period
Given
P = $25,200
i= 11.1% = 0.111
n= 2
compound interest is
C = 25,200 [[tex](1+0.111)^{2}[/tex]-1]
= $5,904.8892
The investment will earn the interest of $5,904.8892.

Based on the fact that the triangles are similar, the length of x is 7.2 cm and the length of y is 7.4 cm
How to find the lengths?If the triangles are similar then it means that the difference between their dimensions can be found by a scale factor.
The scale factor is:
= Dimension of larger similar side / Dimension of smaller similar side
= 11.6 / 5.8
= 2
With a scale factor of 2, then x is:

in exercises 17–30, (a) find the function’s domain, (b) find the function’s range, (c) describe the function’s level curves, (d) find the boundary of the function’s domain, (e) determine if the domain is an open region, a closed region, or neither, and (f) decide if the domain is bounded or unbounded.
The domain of f { (x,y) ∈ R² x² + y² < (3/5)² } is bounded.
What does the math term domain mean?
Range and Domain. The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input.Given f(x,y) = [tex]\frac{1}{\sqrt{9 - 25x^{2} - 25y^{2} } }[/tex]
a) the domain of f is the value of ( x, y) for which 9 - 25x² -25y² >0
9 - 25x² -25y² ⇒ 9/25 > x² + y² ⇒ x² + y² < (3/5)²
∴ domain of f = [ (x,y) ∈ R² : x² + y² < (3/5)²}
B) Let z = f = [tex]\frac{1}{\sqrt{9 -25x^{2} - 25y^{2} } }[/tex]
its range is { z ∈ R² : 3z > 1}
c) let f = k ⇒ k = [tex]\frac{1}{\sqrt{9 - 25x^{2} - 25y^{2} } }[/tex]
k² ( 9 - 25x² - 25y²) = 1 = 9 - 25x² - 25y² = 1/k²
⇒ 25x² + 25y² = 9 - 1/k² ⇒ x² + y² = 1/25( 9 - 1/k²)
The level curves are circles for different k values .
d) The boundary of the function's domain
= { (x,y) ∈ R² x² + y² = (3/5)²}
e) Since x² + y² < (3/5)² is the circular open disk , the domain of f is an open set
f) The domain of f { (x,y) ∈ R² x² + y² < (3/5)² } is bounded.

What is algebraic expression ?When operations like addition, subtraction, multiplication, division, etc. are performed on variables and constants, we obtain algebraic expressions as the mathematical statement. Let's say James and Natalie were tinkering with matchsticks when they had the idea to arrange the sticks into number patterns. James used four matchsticks to make the numeral 4 in the air. Adding three additional matchsticks allowed Natalie to create a pattern with two 4s. They understood that they may continue to add three matchsticks each round to make a total of four. They deduced from this that, generally speaking, 4+ 3(n-1) sticks are required to create a pattern with n numbers of 4s. The algebraic statement 4+ 3(n-1) is referred to here.

What are Real numbers?In the number system, real numbers are only the fusion of rational and irrational numbers. These numbers can generally be used for all arithmetic operations and can also be expressed on a number line. Imaginary numbers, which are often known as unreal numbers since they cannot be stated on a number line, are frequently used to symbolize complex numbers. Real numbers include things like 23, -12, 6.99, 5/2, and so on.Most physical constants, like the universal gravitational constant, and physical variables, including position, mass, speed, and electric charge, are represented using real numbers in the physical sciences.Although the Zermelo-Fraenkel axiomatization of set theory is the method most frequently used to formalize the real numbers, other mathematicians also explore the real numbers using other logical mathematical foundations. Electronic calculators and computers, with a few notable exceptions, do not work with real numbers. Instead, they frequently use floating-point numbers, which are finite-precision approximations that resemble scientific notation.To learn more about Real numbers, refer to:

How many 14-pound hamburgers can you make from 312 pounds of ground beef?
You can make ? hamburgers.
Answer:
You can make 22 burgers.
Step-by-step explanation:
If you have 312 pounds of ground beef and burgers are 14 pounds, divide 312 by 14 ( 312 / 14). This gives you an answer of 22.28 You will have leftovers because 14 does not go into 312 perfectly. You can also check the answer by doing multiplication ( 22 * 14) which gives you 308. You cannot have another burger because 308 + 14 = 322 which is over the amount of beef you have.

y = 3x + 2 is reflected in the line y=-1. What is the equation of the image?
The equation of the image is y = 3x - 4
In this question, we have been given a line y = 3x + 2 is reflected in the line y = -1.
We need to find the equation of the image.
The reflected line must be parallel to the line y = 3x + 2
So, the slope of the image must be equal to the slope of the line y = 3x + 2
The y-intercept of the line y = 3x + 2 is (0, 2)
The distance between point (0, 2) and the line y = -1 is 3 units.
So, the y-intercept of the reflected line must be (0, -4)
With slope m = 3 and y-intercept (0, -4) the equation of the line would be,
y = 3x - 4
Therefore, the equation of the image is y = 3x - 4

Latisha has $40 in her checking account. She makes a withdrawal of $20 and then writes a check for $40. Then she deposits $30.
If Latisha has $40 in her checking account and she makes a withdrawal of $20 and then writes a check for $40, then she deposits $30, then the amount she has in her checking account is $10
The amount she has in her checking account = $40
The amount she withdraw from her account = $20
The amount she writes a check = $40
The deposited amount = $30
To find the final checking account balance we have to use the arithmetic operations
The final balance amount = The amount she has in her checking account -The amount she withdraw from her account - The amount she writes a check + The deposited amount
= 40-20-40+30

Omar has been training for the Candlewood Footrace. The first week he trained, he ran 7 days and took the same two routes each day: 3 miles around the track before work and a longer route through his neighborhood after work. By the end of the week, Omar had run a total of 63 miles.
Which equation can you use to find how many miles, x, Omar ran each day after work?
The equation that can be use to find the how many miles, x, Omar ran each day after work is x = (Total distance he ran in one week - The total distance he run before the work in one week) ÷ 7, he ran 6 miles each days after work
The total number of days he run = 7 days
Total distance he ran in one week = 63 miles
The distance he run before the work = 3 miles
The total distance he run before the work in one week= 7×3
= 21 miles
The total distance he run after the work = 63 - 21
= 42 miles
The equation that can use to find how many mile x, Omar ran each day after work = (Total distance he ran in one week - The total distance he run before the work in one week) ÷ 7
Substitute the values in the equation
= 42/7
= 6 miles
