A large statue is in the shape of a square pyramid. Each side of
the base of the square pyramid is 723 feet long, and the height
is 341 feet.
What is the volume of the statue?

Answers

The formula for the volume of a square pyramid is:

V = (1/3) × base area × height

Since each side of the base of the square pyramid is 723 feet long, the area of the base is:

base area = (723 feet)^2 = 522,129 square feet

Substituting this value and the height of the pyramid (341 feet) into the formula, we get:

V = (1/3) × 522,129 square feet × 341 feet

Multiplying and simplifying, we get:

V = 62,695,147 cubic feet

Therefore, the volume of the statue is approximately 62,695,147 cubic feet.

The quadratic equation represented by the table is:

y = 2x^2 - 4x + 8

How to solve the quadratic equation?

Here we have a table that represents a quadratic equation. Remember that a quadratic equation with a vertex (h, k) and a leading coefficient a can be written as:

y = a*(x - h)^2 + k

Here we can see that the vertex is at (1, 6), replacing that we will get:

y = a*(x - 1)^2 + 6

And we  can see the point (0, 8), replacing these values we will get:

8 = a*(0 - 1)^2 + 6

8 = a + 6

8 - 6 = a = 2

The quadratic is:

y = 2*(x - 1)^2 + 6

Expanding this we will get:

y = 2*(x^2 - 2x + 1) + 6

y = 2x^2 - 4x + 2 + 6

y = 2x^2 - 4x + 8

That is the quadratic equation.

Jamie invested $1,500 in a savings account. The account earns 3.8% interest, compounded monthly. How much money will Jamie have in her account after 4 years if she does not make any deposits or withdrawals? (round to the nearest dollar)
A $2,341

C $1,257
D $1,557

Answers

We can say that after answering the offered question As a result, Jamie interest will have $1,746 in her account after four years. Option B is the correct answer.

what is interest ?

Simple interest is calculated via dividing the investment by the interest rate, the duration of the loan, and perhaps other factors. In marketing, the formula is simple: return = principal + interest + hours. This method makes it easiest to calculate interest. The most common approach to compute interest is to use the percentages of the principle balance. If he borrows $100 from a buddy and promises to repay that with 5% interest, he will only pay his percentage of the total interest. $100 (0.05) = $5. When you borrow money, you must charge interest and extending when you lend it. The most often, interest is determined as an indicator of the overall of the loan balance. This percentage is known as the loan's interest.

To answer this problem, we can utilise the compound interest formula:

[tex]A = P(1 + r/n)^(nt) (nt)[/tex]

where A is the total amount

P = the initial principal ($1,500 in this example).

r represents the yearly interest rate (3.8%).

n denotes the number of times interest is compounded per year (12 for monthly)

t denotes the number of years (4 in this case)

When we plug in the values, we get:

[tex]A = 1500(1 + 0.038/12)^(12*4) \sA ≈ 1745.99[/tex]

As a result, Jamie will have $1,746 in her account after four years. Option B is the correct answer.

4.4. A weight lifter increases his body mass by 15% after some heavy training. His new body mass is 78 kg. He claims that he has gained approximately 10 kg of weight after the training session. State whether his claim is valid or not by showing all the necessary calculations.​

Answers

Answer:

Step-by-step explanation:

We can start by finding the weight lifter's original body mass before the training session:

Let x = original body mass

Then, we know that 15% of x is equal to 78 kg - x:

0.15x = 78 - x

1.15x = 78

x = 78/1.15

x ≈ 67.83 kg

Therefore, the weight lifter's original body mass was approximately 67.83 kg.

Now, let's find the difference between the weight lifter's new body mass and his original body mass:

78 kg - 67.83 kg ≈ 10.17 kg

So, the weight lifter did indeed gain approximately 10 kg of weight after the training session. Therefore, his claim is valid.

A 16 foot ladder is propped up against the roof of a house. The angle of elevation is 62 degrees. How tall is the house?

Answers

Answer is below.

Let's call the height of the house "h".

The ladder is propped up against the house, forming a right triangle with the wall of the house and the ground. The ladder is the hypotenuse of the triangle, and the height of the house is one of the legs.

We know that the length of the ladder is 16 feet, and the angle of elevation is 62 degrees. We can use trigonometry to find the height of the house.

The trigonometric function that relates the angle of elevation to the height and length of the ladder is the tangent function:

tan(62) = h/16

To solve for h, we can multiply both sides by 16:

16 tan(62) = h

Using a calculator, we can evaluate the tangent of 62 degrees to get:

16 tan(62) ≈ 28.6

So the height of the house is approximately 28.6 feet.

The solution for x in the equation -7x/5 + 4 = -1/2x - 7/2 is 5, and the other solutions are listed below

Solving for x in the equation

Given that

-7x/5 + 4 = -1/2x - 7/2

Multiply through by 10

-14x + 40 = 5x - 35

Evaluate the like terms

-19x = -95

So, we have

The number of adult tickets

Let x be the number of adult tickets sold.

So, the number of student tickets sold is 2x.

The total number of tickets sold is 444. Therefore:

x + 2x = 444

Combining like terms:

3x = 444

Dividing both sides by 3:

x = 148

Therefore, 148 adult tickets were sold.

The readings from the graph

The slope

To read the slope off the graph, we can use the formula:

slope = (change in y) / (change in x)

Using the points, we can calculate:

slope = (-2 - 1) / (3 - 1)

slope = -1.5

So the slope of the line is -1.5.

The y-intercept value

We can look at where the line intersects the y-axis on the graph. From the graph, it looks like the y-intercept is around y = 2.5.

The y-intercept point

Using the solution in (b), the estimated y-intercept point is (0, 2).

The linear equation

Rearrange the equation

To rearrange the equation into slope-intercept form, we need to isolate y on one side of the equation:

5x + 3y = 15

Subtract 5x from both sides:

3y = -5x + 15

Divide both sides by 3:

y = (-5/3)x + 5

So the equation in slope-intercept form is y = (-5/3)x + 5.

The slope

b) The slope of the line is the coefficient of x in the equation when it is in slope-intercept form.

Therefore, the slope of the line is -5/3.

The y-intercept of the line

This is the value of y when x = 0.

From the equation in slope-intercept form, we can see that when x = 0, y = 5.

So, the y-intercept of the line is 5.

How many distinct ways are there to arrange 3 yellow marbles, 3 green marbles, 2 red marbles, and 2 blue marbles in a row?

Answers

There are 3150 distinct ways to arrange the marbles in a row.

What is Combination ?

In mathematics, combination is a way of selecting a group of objects from a larger set, without regard to the order in which the objects are selected. Combinations are also sometimes called "unordered selections" or "combinatorial subsets".

To solve this problem, we can use the formula for permutations with repetition. We have a total of 10 marbles, but some of them are repeated. Specifically, we have:

3 yellow marbles (repeated)

3 green marbles (repeated)

2 red marbles (repeated)

2 blue marbles (repeated)

So the number of distinct ways to arrange these marbles in a row is:

(10!) ÷ (3! x 3! x 2! x 2!)

The factorials in the denominator account for the repetition of each color. We divide by them to eliminate the overcounting that would occur if all the marbles were unique.

Simplifying this expression, we get:

(10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)÷(3 x 2 x 1 x 3 x 2 x 1 x 2 x 1 x 1 x 1)

which equals:

(10 x 9 x 8 x 7 x 6 x 5 x 4) ÷ (3 x 3 x 2 x 2)

Simplifying further, we get:

(10 x 3 x 3 x 3 x 2 x 2 x 7 x 5) ÷ (3 x 3 x 2 x 2)

which equals:

(10 x 3 x 3 x 7 x 5)

which finally equals:

Answer:

The method that might have been used to result in Garcia winning is the Instant RunOff method.

In this method, voters rank the candidates in order of preference. If no candidate has a majority of first-choice votes, the candidate with the fewest votes is eliminated, and their votes are redistributed to the remaining candidates according to the second-choice preferences of the voters who supported the eliminated candidate. This process is repeated until one candidate has a majority of the votes.

In the preference ballot provided, Garcia received the most first-choice votes with a total of 26, but did not receive a majority of the votes. Therefore, the Instant RunOff method could have been used to determine the winner by redistributing the votes of the eliminated candidates (Müller and Ivanov) to the remaining candidates. Based on the preferences of the voters who chose Müller and Ivanov as their first choice, it is possible that the redistributed votes would have favored Garcia, leading to a majority win for Garcia.

The Instant RunOff method might not be fair to the other nominees because it can result in a candidate winning with a majority of second-choice or even lower preferences, rather than being the first choice of the majority of voters. This means that the candidate who is ultimately chosen may not have broad support, and may not be the candidate that the most voters actually prefer. Additionally, the method can be influenced by strategic voting, where voters rank their choices based on who they think is most likely to win, rather than their actual preferences. This can result in outcomes that do not accurately reflect the preferences of the voters.

If such a child is at the 69th percentile, how old is that child?

Answers

The child at the 69th percentile is 5.5279 years οld.

Hοw tο fin the 69th percentile?  

The age οf the children in kindergarten οn the first day οf schοοl is unifοrmly distributed between 4.81 and 5.71 years οld. We can find the tοtal prοbability οf the child being between 4.81 and 5.71 years οld by subtracting the prοbability οf the child being yοunger than 4.81 frοm the prοbability οf the child being yοunger than 5.71:

P(4.81 ≤ age ≤ 5.71) = P(age ≤ 5.71) - P(age < 4.81)

The prοbability οf the child being yοunger than 4.81 is 0 since the age cannοt be negative.

The prοbability οf the child being yοunger than 5.71 can be calculated as:

P(age ≤ 5.71) = (5.71 - 4.81) / (5.71 - 4.81) = 1

Therefοre,

P(4.81 ≤ age ≤ 5.71) = 1 - 0 = 1

This means that the prοbability οf the child being οlder than 5 years οld is:

P(age > 5) = P(5.00 < age ≤ 5.71) = 1 - P(age ≤ 5.00) = 1 - [(5.00 - 4.81) / (5.71 - 4.81)] = 0.7018

Sο the prοbability οf the child is οlder than 5 years οld is 0.7018.

Tο find the age οf a child at the 69th percentile, we need tο find the age x such that the prοbability οf the child being yοunger than x is 0.69.

Let's call the age at the 69th percentile x. Then we have:

P(age < x) = 0.69

We can sοlve fοr x as fοllοws:

( x - 4.81 ) / ( 5.71 - 4.81 ) = 0.69

x - 4.81 = 0.69 ( 5.71 - 4.81 )

x - 4.81 = 0.69

x = 4.81 + 0.69 ( 5.71 - 4.81 )

Answer:
Part a:

[tex]A(x)=10x^2+53x+63[/tex]

Part b:
2nd degree polynomial.

Part c:
Check step by step.

Step-by-step explanation:

since the sides of the rectangle are (2x+7) and (5x+9), the area is given by the product of the sides:

[tex]A=(2x+7)(5x+9)=10x^2+18x+35x+63=10x^2+53x+63[/tex]

So the area as a function of X is given by:
[tex]A(x)=10x^2+53x+63[/tex]

Notice is a second degree polynomial in standard form

To ensure part c, notice we can also multiply the sides in different order. This is A*B must be B*A for the sides of the rectangle. Lets check

[tex]A=(5x+9)(2x+7)=10x^2+35x+18x+63=10x^2+53x+63[/tex]
Since we obtained the same answer in part A the closure property for multiplication is check for the polynomial.

Let G be a group with lGl=77. Prove that every proper subgroup is cyclic.

Answers

Every proper subgroup of G is cyclic.

What is subgroup?

In abstract algebra, a subgroup is a subset of a group that is itself a group under the same operation as the original group. More precisely, a subgroup H of a group G is a subset of G that satisfies the following three conditions:

The identity element of G is in H.H is closed under the group operation of G.Every element in H has an inverse in H.What are cyclic subgroups?

A cyclic subgroup is a subgroup of a group that is generated by a single element. In other words, a subgroup H of a group G is cyclic if there exists an element a in G such that every element of H can be written as a power of a, and H is the smallest subgroup of G containing a.

In the given question,

Let H be a proper subgroup of G. Since H is a proper subgroup, we have lHl < lGl = 77.

Now, by Lagrange's Theorem, the order of any subgroup of G must divide the order of G. That is, lHl divides lGl = 77.

Since H is a proper subgroup, we have lHl > 1. Therefore, lHl can only be 7, 11, or 77 (the divisors of 77).

Suppose lHl = 7. Then, by Lagrange's Theorem, the elements of G are partitioned into disjoint cosets of H, each of size 7. But 77 is not divisible by 7, so there cannot be a whole number of cosets. Therefore, this case is not possible.

Similarly, suppose lHl = 11. Then, the elements of G are partitioned into disjoint cosets of H, each of size 11. But 77 is not divisible by 11, so there cannot be a whole number of cosets. Therefore, this case is also not possible.

Thus, we are left with the case where lHl = 77. But this implies that H = G, which contradicts the fact that H is a proper subgroup. Therefore, this case is also not possible.

We have exhausted all possibilities for the order of H, and in each case, we have arrived at a contradiction. Therefore, the assumption that there exists a proper non-cyclic subgroup of G must be false.

Hence, every proper subgroup of G is cyclic.

In an arithmetic sequence, the sum of the first 8 terms is 88. The product of the 1st and the 8th terms is 120. Calculate values for the 1st term.​

Answers

Answer: Let's call the first term of the arithmetic sequence "a", and the common difference between the terms "d".

Then, we know that the sum of the first 8 terms is 88, so we can write:

a + (a + d) + (a + 2d) + ... + (a + 7d) = 88

Using the formula for the sum of an arithmetic sequence, we can simplify this to:

8a + 28d = 88

We also know that the product of the 1st and 8th terms is 120, so we can write:

a(a + 7d) = 120

Now we have two equations with two variables. We can solve for one of the variables in terms of the other and substitute into the other equation to solve for the remaining variable.

Solving the first equation for d:

d = (88 - 8a)/28

Substituting into the second equation:

a(a + 7[(88-8a)/28]) = 120

Multiplying both sides by 28 to eliminate the fraction:

28a^2 + 154a - 960 = 0

We can factor this quadratic equation as:

(2a - 15)(14a + 64) = 0

So either 2a - 15 = 0 or 14a + 64 = 0. Solving for "a" in each case, we get:

a = 15/2 or a = -64/14

Since we're looking for the first term of the sequence, which must be positive, we can discard the negative value and conclude that the first term is:

a = 15/2

Therefore, the first term of the arithmetic sequence is 7.5.
