Given m < AFB = 40, m < BAF = 90, and m < AGD = 86. Find measure of arc AC.
=================================================
Explanation:
Refer to the figure below.
Focus on triangle ABF. Angle AFB = 40 is marked in red. Angle BAF = 90 is marked in blue. The missing angle is 180-90-40 = 50 which is angle ABF.
Inscribed angle ABF = 50 doubles to arc AC since this inscribed angle subtends the arc in question. I'm using the inscribed angle theorem.
arc AC = 2*(angle ABF) = 2*50 = 100 degrees
Note: We don't need the fact that angle AGD = 86
Mr.Smith has p pounds of cookie dough. He is going to split it equally among his three children. Each child will get 0.42 pounds of cookie dough. Write and solve an equation that can be used to determine the weight of the cookie dough Mr. Smith has.
Answer:
p = 1.26
Step-by-step explanation:
We know that the total weight (p) is going to be split equally (divided) by 3.
We also know that divided weight will be equal to 0.42 pounds.
p / 3 = 0.42
To solve:
multiply both sides by 3 to cancel the division by 3
p = 1.26
To test this you could divide 1.26 by 3 again to get 0.42

"Last week you sold 30, 45, 50, 75, and 80 units each day of the week, in that order. On average, how many units did you sell per day?"
Answer:
56
Step-by-step explanation:
1) Add together all numbers. 30+45+50+75+80 = 280.
2) Divide result by amount of numbers. 280/5 = 56
3) You are welcome. :)
On an average, you sold 56 unit per, day.
What is average?A number that is calculated by adding quantities together and then dividing the total by the number of quantities.
Given that, Last week you sold 30, 45, 50, 75, and 80 units each day of the week.
To find the average, we will, first add together all numbers and then divide the result by the sum of numbers.
Therefore,
Adding together all numbers = 30+45+50+75+80 = 280.
Divide result by amount of numbers = 280/5 = 56
Hence, On an average, you sold 56 unit per, day.

A cube has total surface area 150 cm square, find the volume of cube. somebody help me to solve this.
We have been provided with the total surface area of cube that is 150cm².
So here we will first find out the value of a side of cube.
★ Total surface area of cube :-
T.S.A. = 6a²Here,
a is side of cubePutting the values,
6a² = 150cm²
a² = 150 / 6
a² = 50 / 2
a² = 25
a = √25
a = 5
Henceforth,
Side of a cube is of 5 cm.★ Finding out volume of cube :-
As we know that volume of cube is calculated by the formula :
V = a³Putting the values,
V = 5³
V = 5 × 5 × 5
V = 25 × 5
V = 125
Henceforth,
Volume of cube is of 125 cm³.

Please Help!!!!!!!! In a recent year,24.7% of all registered doctors were female. If there were 43,200 female registered doctors that year, what was the total number of registered doctors?
Round your answer to the nearest whole number.
This is one single number just a bit under 175 thousand. Delete the comma if needed.
========================================================
Work Shown:
x = number of total doctors
24.7% of x = number of female doctors
0.247x = 43200
x = 43200/(0.247)
x = 174,898.785425101 approximately
x = 174,899 when rounding to the nearest whole number
Height of a Toy Rocket A toy rocket (not internally powered) is launched straight up from the top of a building 50 ft tall at an initial velocity of 200 ft per sec. a. Give the function that describes the height of the rocket in terms of timet b. Determine the time at which the rocket reaches its maximum height and the maximum height in feet. c. For what time interval will the rocket be more than 300 ft above ground level? d. After how many seconds will it hit the ground?
The height of the toy is an illustration of the height function
The function of the toy velocityThe given parameters are:
Initial velocity, Vo = 200 ft per secInitial height, H = 50 ftThe function of the height is calculated as:
h(t) = -16t² + Vot + H
This gives
h(t) = -16t² + 200t + 50
Hence, the velocity function is h(t) = -16t² + 200t + 50
The time of maximum heightIn (a), we have:
h(t) = -16t² + 200t + 50
Differentiate
h'(t) = -32t + 200
Set to 0
-32t + 200 = 0
Subtract 200 from both sides
-32t = -200
Divide both sides by -32
t = 6.25
Substitute 6.25 for t in h(t)
h(6.25) = -16 *6.25² + 200 * 6.25 + 50
h(6.25) = 675
Hence, the time to reach the maximum height is 6.25 seconds and the maximum height is 675 feet
When the rocket will be at a height more than 300This is represented as
h(t) >300
So, we have:
-16t² + 200t + 50 > 300
Subtract 300 from both sides
-16t² + 200t - 250 > 0
Using a graphical calculator, we have:
t = 11.09s and t = 1.41 s
Hence, the rocket will be at a height more than 300 at 11.09s and 1.41 s
When it will hit the ground?This means that
h(t) = 0
So, we have:
-16t² + 200t + 50 = 0
Using a graphical calculator, we have:
t = 12.75
Hence, the rocket will hit the ground at 12.75s

f(x) = (2x³ + 1 + x²)/(x² + 9) as a sum of two functions g(x) and h(x), where g is an odd function and h is an even function is f(x) = 2x³/(x² + 9) + (1 + x²)/(x² + 9).
To answer the questions, we need to know what functions are
What are functions?A function is a mathematical expression that shows the relationship between two variables.
Types of functionOdd functions - These are functions in which f(-x) = -f(x)Even functions - These are functions in which f(-x) = f(x)Neither - When the function is neither even nor odd.Since f(x) = (2x³ + 1 + x²)/(x² + 9).
The odd part of f(x)Its odd part g(x) = [f(x) - f(-x)]/2
So, g(x) = [f(x) - f(-x)]/2
= [(2x³ + 1 + x²)/(x² + 9) - (2(-x)³ + 1 + (-x)²)/((-x)² + 9)]/2
= [(2x³ + 1 + x²)/(x² + 9) - (-2x³ + 1 + x²)/(x² + 9)]/2
= (2x³ + 1 + x² + 2x³ - 1 - x²)/2(x² + 9)
= 4x³/2(x² + 9)
g(x) = 2x³/(x² + 9)
The even part of f(x)
Its even part h(x) = [f(x) + f(-x)]/2
So, h(x) = [f(x) + f(-x)]/2
= [(2x³ + 1 + x²)/(x² + 9) + (2(-x)³ + 1 + (-x)²)/((-x)² + 9)]/2
= [(2x³ + 1 + x²)/(x² + 9) + (-2x³ + 1 + x²)/(x² + 9)]/2
= (2x³ + 1 + x² - 2x³ + 1 + x²)/2(x² + 9)
= 2(1 + x²)/2(x² + 9)
h(x) = (1 + x²)/(x² + 9)
So, f(x) = g(x) + h(x)
f(x) = 2x³/(x² + 9) + (1 + x²)/(x² + 9)
So, f(x) = (2x³ + 1 + x²)/(x² + 9) as a sum of two functions g(x) and h(x), where g is an odd function and h is an even function is f(x) = 2x³/(x² + 9) + (1 + x²)/(x² + 9).

is 5/74 rational or irrational?
Answer:
Rational
Step-by-step explanation:
5.74 is the same as 5.74 over 1. In other words, 5.74 can be written with a numerator and denominator, like this:
5.74 = 5.74/1
5.74 x 100/ 1 x 100
You can multiply the numerator and denominator of any fraction by the same number and keep the value of the fraction the same. Here we will multiply the numerator and denominator by 100 to get rid of the decimal point.
5.74 × 100/ 1 × 100
When we calculate the numerator and the denominator above, we get this fraction:
574/100
The fraction above is the same as 5.74. Furthermore, the numerator and the denominator of the fraction above are integers. Therefore, we can conclude that the answer to "Is 5.74 a rational number?" is yes.
