Answer:
$690
Step-by-step explanation:
To find the interest earned in three years, we can use the interest formula
Interest = Principal x Rate x Time
- Principal = $600 (the amount John deposited)
- Rate = 5% per year (as a decimal, this is 0.05)
- Time = 3 years
Interest = $600 x 0.05 x 3 = $90
Therefore, John will earn $90 in interest over 3 years.
To find his account balance, including interest, after 3 years, we can simply add the interest earned to the original principal:
Account balance = Principal + Interest
Account balance = $600 + $90 = $690
Therefore, John's account balance, including interest, after 3 years will be $690.
Answer:
Simple interest: 690, compound interest: 694.5
Step-by-step explanation:
Simple interest = PRT/100 = 600*5*3/100 = 90 = 600+90 = 690
compound interest = P(1+r/100)^n = 600(1+5/100)^3 = 694.5
Your answer depends on if its simple or compound interest if not said so either of the answers I have given to you is right :)

Case 1
f(x) + g(x) = 2 - x - x²
Case 2
g(x) - f(x) = x² - x
Case 3
g(x) · f(x) = (1 - x) · (1 - x²) = 1 - x - x² + x³

A publisher for a promising new novel figures fixed costs (overhead, advances, promotion, copy editing, typesetting, and so on) at $51,000, and variable costs (printing, paper, binding, shipping) at $1.50 for each book produced. If the book is sold to distributors for $12 each, how many must be produced and sold for the publisher to break even?
The publisher must produce and sell approximately 4,857 books to break even.
Let's denote the number of books produced and sold as "x."
The total fixed cost is given as $51,000.
The variable cost per book is $1.50, and since x books are produced and sold, the total variable cost would be 1.50x.
The selling price per book is $12, and since x books are sold, the total revenue would be 12x.
To break even, the total revenue must equal the total cost:
Total Revenue = Total Cost
12x = 51,000 + 1.50x
Subtracting 1.50x from both sides:
12x - 1.50x = 51,000
10.50x = 51,000
Dividing both sides by 10.50:
x = 51,000 / 10.50
x ≈ 4,857
Therefore, the publisher must produce and sell approximately 4,857 books to break even.

The Length of the ant to inches before we can compare the two lengths. We do this by dividing the numerator (3) by the denominator (32), which gives us a decimal of approximately 0.09375 inches.
To find how many times greater the length of the green anole lizard is compared to the crazy ant, we need to divide the length of the lizard by the length of the ant:
Length of lizard / Length of ant = 6 / (3/32) = 6 * (32/3) = 64
Therefore, the length of the green anole lizard is 64 times greater than the length of the crazy ant.
The correct answer is (D) 64.
It is important to pay attention to the units when working with ratios and proportions. In this case, the length of the lizard is given in inches, while the length of the ant is given in fractions of an inch.

What is the probability that the mean amount of cereal in these boxes is less than 9.65 ounces?
What is the probability that the mean amount of cereal ¯
in 5 randomly selected boxes is at most 9.65?
The probability that the mean amount of cereal in 5 randomly selected boxes is at most 9.65 ounces is 0.4808.
What is the probability?The Central limit theorem is used to find the probability
Data given:
sample size = 5.
mean, μ = 9.70 ounces
standard deviation, σ = 0.03 ounce.
To calculate the probability, we determine the z-score corresponding to the sample mean of 9.65 ounces using the z-score formula.
z = (x - μ) / (σ / √n)wherex is the sample mean,
μ is the population mean,
σ is the population standard deviation, and

Answers to the aforementioned questionsa) To determine the number of ways a dance committee of 8 students can be chosen, we need to consider the total number of eligible students and choose a group of 8 from them.
Total number of eligible students = 7 freshmen + 10 sophomores + 9 juniors + 7 seniors = 33 students
The number of ways to choose a committee of 8 students from a pool of 33 is given by the combination formula:
C(33, 8) = 33! / (8!(33-8)!) = 8,535,316
Therefore, there are 8,535,316 ways to choose a dance committee of 8 students.
b) To choose a dance committee consisting of 2 freshmen, 2 sophomores, 2 juniors, and 2 seniors,
Number of ways to choose 2 freshmen from 7 freshmen = C(7, 2) = 21
Number of ways to choose 2 sophomores from 10 sophomores = C(10, 2) = 45
Number of ways to choose 2 juniors from 9 juniors = C(9, 2) = 36
Number of ways to choose 2 seniors from 7 seniors = C(7, 2) = 21
Total number of ways to choose the dance committee = 21 * 45 * 36 * 21 = 497,070
Therefore, there are 497,070 ways to choose a dance committee consisting of 2 freshmen, 2 sophomores, 2 juniors, and 2 seniors.
c) To choose a dance committee consisting of 4 juniors and 4 seniors,
Number of ways to choose 4 juniors from 9 juniors = C(9, 4) = 126
Number of ways to choose 4 seniors from 7 seniors = C(7, 4) = 35
Total number of ways to choose the dance committee = 126 * 35 = 4,410
Therefore, there are 4,410 ways to choose a dance committee consisting of 4 juniors and 4 seniors.
d) The probability of selecting a committee consisting of 2 freshmen, 2 sophomores, 2 juniors, and 2 seniors

what is that square root of 107.6
The square root of 107.6 is approximately 10.372
To find the square root of 107.6, we can use a calculator or use the following procedure:
Make an initial estimate:
We know that the square root of 100 is 10, so we can estimate that the square root of 107.6 is slightly more than 10.
Use the formula: We can use the following formula to improve our estimate:
x(n+1) = (x(n) + a/x(n))/2
where x(n) is the nth estimate of the square root of a, and a is the number we want to find the square root of.
Apply the formula: Using the estimate of 10, we get:
x(1) = (10 + 107.6/10)/2 = 10.38
Now we use this new estimate to get a better one:
x(2) = (10.38 + 107.6/10.38)/2 = 10.371

Thus, the problem is solved.
Answer:
[tex]\tan 15^{\circ} = 2 - \sqrt{3}[/tex]
Step-by-step explanation:
To find the exact value of tan 15°, we can use trigonometric identities and the unit circle.
We know that tan(x) can be expressed as the ratio of sin(x) and cos(x). We can also write 15° as (60° - 45°).
Therefore, tan 15° can be expressed as:
[tex]\tan15^{\circ}=\tan(60^{\circ}-45^{\circ})=\dfrac{\sin(60^{\circ}-45^{\circ})}{\cos(60^{\circ}-45^{\circ})}[/tex]
Now use the trigonometric angle identities to rewrite the ratio in terms of sin 60°, cos 60°, sin 45° and cos 45°.
[tex]\boxed{\begin{minipage}{6.5 cm}\underline{Trigonometric Angle Identities}\\\\$\sin (A - B)=\sin A \cos B - \cos A \sin B$\\\\$\cos (A - B)=\cos A \cos B + \sin A \sin B$\\\end{minipage}}[/tex]
Therefore:
[tex]\begin{aligned}\tan15^{\circ}&=\dfrac{\sin(60^{\circ}-45^{\circ})}{\cos(60^{\circ}-45^{\circ})}\\\\&=\dfrac{\sin60^{\circ}\cos45^{\circ}-\cos60^{\circ}\sin45^{\circ}}{\cos 60^{\circ} \cos 45^{\circ}+ \sin 60^{\circ}\sin 45^{\circ}}\end{aligned}[/tex]
In the unit circle, the cosine of an angle is represented by the x-coordinate of a point on the circle, and the sine of an angle is represented by the y-coordinate of that same point → (x, y) = (cos θ, sin θ). Therefore, we can use the unit circle to identity the values of sin 60°, cos 60°, sin 45° and cos 45°:
[tex]\sin 60^{\circ}=\dfrac{\sqrt{3}}{2}[/tex]
[tex]\cos 60^{\circ}=\dfrac{1}{2}[/tex]
[tex]\sin 45^{\circ}=\dfrac{\sqrt{2}}{2}[/tex]
[tex]\cos 45^{\circ}=\dfrac{\sqrt{2}}{2}[/tex]
Substitute these into the equation and simplify:
[tex]\begin{aligned}\tan15^{\circ}&=\dfrac{\sin(60^{\circ}-45^{\circ})}{\cos(60^{\circ}-45^{\circ})}\\\\&=\dfrac{\sin60^{\circ}\cos45^{\circ}-\cos60^{\circ}\sin45^{\circ}}{\cos 60^{\circ} \cos 45^{\circ}+ \sin 60^{\circ}\sin 45^{\circ}}\\\\&=\dfrac{\dfrac{\sqrt{3}}{2}\cdot \dfrac{\sqrt{2}}{2}-\dfrac{1}{2}\cdot \dfrac{\sqrt{2}}{2}}{\dfrac{1}{2}\cdot \dfrac{\sqrt{2}}{2}+ \dfrac{\sqrt{3}}{2}\cdot \dfrac{\sqrt{2}}{2}}\\\\\end{aligned}[/tex]
[tex]\begin{aligned}&=\dfrac{\dfrac{\sqrt{2}}{2} \left(\dfrac{\sqrt{3}}{2}-\dfrac{1}{2}\right)}{\dfrac{\sqrt{2}}{2} \left(\dfrac{1}{2}+ \dfrac{\sqrt{3}}{2}\right)}\\\\&=\dfrac{\dfrac{\sqrt{3}}{2}-\dfrac{1}{2}}{ \dfrac{1}{2}+ \dfrac{\sqrt{3}}{2}}\\\\&=\dfrac{\dfrac{\sqrt{3}-1}{2}}{\dfrac{1+\sqrt{3}}{2}}\\\\&=\dfrac{\sqrt{3}-1}{1+\sqrt{3}}\end{aligned}[/tex]
Simplify further by multiplying the numerator and denominator by the conjugate of the denominator:
[tex]\begin{aligned}&=\dfrac{\sqrt{3}-1}{1+\sqrt{3}}\cdot \dfrac{1-\sqrt{3}}{1-\sqrt{3}}\\\\&=\dfrac{(\sqrt{3}-1)(1-\sqrt{3})}{(1+\sqrt{3})(1-\sqrt{3})}\\\\&=\dfrac{\sqrt{3}-3-1+\sqrt{3}}{1-\sqrt{3}+\sqrt{3}-3}\\\\&=\dfrac{2\sqrt{3}-4}{-2}\\\\&=-\sqrt{3}+2\\\\&=2-\sqrt{3}\end{aligned}[/tex]

Step-by-step explanation:
Solution Given:
radius(r)=12
In right-angled triangle
Hypotenuse = 18
base angle =60°
Note:
In a right-angled triangle, we can use the trigonometric ratios sine, cosine, and tangent to relate the angles and sides of the triangle.
Here are the trigonometric ratios for a right-angled triangle:
Sine (sin): The sine of an angle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
[tex]\boxed{\bold{sin(A) =\frac{ opposite}{hypotenuse}}}[/tex]
Cosine (cos): The cosine of an angle is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse.
[tex]\boxed{\bold{cos(A) = \frac{adjacent}{hypotenuse}}}[/tex]
Tangent (tan): The tangent of an angle is the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
[tex]\boxed{\bold{tan(A) =\frac{ opposite}{adjacent}}}[/tex]
Now for the question:
Over here the relation between opposite or height and hypotenuse is given by Sine, So using this formula:
[tex]\bold{sin(60^0) =\frac{ opposite\:or\ height}{18}}[/tex]
doing criss-cross multiplication:
Sin 60°*18=opposite or height
[tex]\frac{\sqrt{3}}{2}*18[/tex] =opposite or height
opposite or height(h)=[tex]9\sqrt{3}[/tex]
Again,
We have
[tex]\boxed{\bold{Volume\:of\:cylinder= \pi * r^2 * h}}[/tex]
where:
π (pi) is a mathematical constant approximately equal to 3.14
r is the radius of the base of the cylinder
h is the height of the cylinder
Now Substituting value
[tex]Volume = \pi * r^2 * h\\Volume=3.14*12^2*9\sqrt{3}\\Volume=\bold{7048.48 ft^3}[/tex]

Step-by-step explanation:
Volume of the square pyramid = 1/3 * base area * height
= 1/3 (3 x 3) * 4 = 12 yd^3
Consider this system of equations: 2x + 1/4 y= 3 (equation A) 2/3 x - y = 6 (equation B)
The expressions that give the value of y are ___ and ___ .
The solution for the given system is ___.
The options given for the first blank space are A - 38, A - (38/2), 2A - 3B, (A/3) + B.
The options for the second blank space are A + 38, A + (38/2), (A/3) - B, and ((A/3) - 2B.
The options given for the first blank space are (27/13, 60/13), (-27/13 60/13), (27/13, -60/13), (-27/13, -60/13)
The solution to the system of equations are ( 27/13 , -60/13 )
Given data ,
Let the system of equations be A and B
where 2x + ( 1/4 )y = 3 be equation (1)
And , ( 2/3 )x - y = 6 be equation (2)
On simplifying , we get
Multiply by 3 on equation (2) , we get
2x - 3y = 18 be equation (3)
Subtracting equation (1) from (3) , we get
-3y - (1/4)y = 15
-13/4y = 15
Divide by -13/4 on both sides , we get
y = -60/13
Now , the value of x is given by
2x + ( 1/4 ) ( -60/13 ) = 3
2x - ( 60/52 ) = 3
Adding 60/52 on both sides , we get
2x = 3 + 60/52
2x = 216/52
Divide by 2 on both sides , we get
x = 216/104
On simplifying , we get
x = 27/13
Hence , the solution is ( 27/13 , -60/13 )

Aplica la propiedad conmutativa y calcula M +N:
29 x M=31 x (N + 2)
Using the commutative property we can get an equation that depends on the sum of the two variables:
(M + N) = (62 - 2N)/29
How to apply the commutative property?The commutative property of the multiplication and sum means that we can permutate the variables:
A*B = B*A
A + B = B + A
In this case, we have the equation:
29*M = 31*(N + 2)
We can distribute the product to get:
29*M = 31*N + 31*2
29*M = 31*N + 62
Now we want to find the value of the sum of the variables, because we have only one equation we can't do that (two variables means that we need two equations) But we can write an expression that depends on the sum of the two variables.
29M + 31N = 62
And now use the commutative property to write:
(29M + 29N) + 2N = 62
(M + N) = (62 - 2N)/29

Answer:
Pick c, 2/27
Step-by-step explanation:
Bag #1 has 4 + 6 + 3 + 5 = 18 total tiles.
4 are black.
So prob (black) from bag 1 = 4/18.
Bag #2 has 3 + 2 + 3 + 1 = 9 total tiles.
3 are black.
So prob(black) from bag 2 = 3/9.
Multiply those 2 independent probabilities together.
(4/18) x (3/9) = (2/27)

find the average cost function C for the given total cost function
C(x) = 2,100 + 4x − 0.0003x2
The average cost function for the given total cost function is AC(x) = 2,100/x + 4 - 0.0003x.
To find the average cost function C, we need to divide the total cost function C(x) by the quantity of output produced, which is represented by x.
The formula for average cost (AC) is:
AC(x) = C(x) / x
Plugging in the given values, we have:
AC(x) = (2,100 + 4x - 0.0003x2) / x
Simplifying this expression, we get:
AC(x) = 2,100/x + 4 - 0.0003x
Therefore, the average cost function C(x) is:
C(x) = 2,100/x + 4x - 0.0003x2
This function represents the average cost per unit of output, taking into account fixed costs (2,100) and variable costs (4x - 0.0003x) that increase as output increases.
It's important to note that the cost function C(x) is quadratic, which means that the average cost function C(x) will have a U-shaped curve.
This is because initially, as output increases, fixed costs are spread out over a larger quantity of output, leading to a decrease in average cost.
However, at a certain point, the increasing variable costs will outweigh the decreasing fixed costs, causing average cost to increase again.
Overall, knowing the average cost function can be useful for businesses to make decisions about pricing, production levels, and cost management strategies.
