The height of the monument is 30 meters.

We have,

Let's assume the height of the monument is "h" meters.

From the top of the building, the angle of elevation to the top of the monument is equal to the angle of depression to the foot of the monument. This forms a right triangle with the building, the monument, and the ground.

In this triangle, the opposite side of the angle of elevation is the height of the building, which is given as 30 meters.

The opposite side of the angle of depression is the height of the monument, which is "h" meters.

Since the angles of elevation and depression are equal, the triangle is an isosceles triangle.

Therefore, the opposite sides are equal in length.

By setting up the equation:

h = 30

Thus,

The height of the monument is 30 meters.

What is sequence?

In mathematics, a sequence is a list of components, usually numbers, where the components' order is important. Here, everything fits into a predetermined pattern. In real life, we encounter sequences frequently. Sequences include things like house numbers in a row, salary increases over time (by a set dollar amount or percentage), book pages, etc.

A list of numbers (or other components) that follow a specific pattern is called a sequence. Olivia, for instance, has been given a job with a starting monthly pay of $1,000 and a $500 annual raise. Are you able to determine her monthly pay for the first three years? $1000, $1500, and $2000 will be the amounts. Observe how Olivia's pay over a number of years forms a sequence because the numbers always increase by $500, following a pattern.

The formula for density (ρ) is:

Density (ρ) = Mass (m) / Volume (V)

Step-by-step explanation:

Where:

Using the binomial distribution, it is found that there is a 0.857 = 85.7% probability that at least 2 of the rolls come up as a 3 or a 4.

For each die, there are only two possible outcomes, either a 3 or a 4 is rolled, or it is not. The result of a roll is independent of any other roll, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

The parameters are:

In this problem:

The desired probability is:

\(P(X \geq 2) = 1 - P(X < 2)\)

In which:

\(P(X < 2) = P(X = 0) + P(X = 1)\)

Then

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 0) = C_{9,0}.(0.3333)^{0}.(0.6667)^{9} = 0.026\)

\(P(X = 1) = C_{9,1}.(0.3333)^{1}.(0.6667)^{8} = 0.117\)

Then:

\(P(X < 2) = P(X = 0) + P(X = 1) = 0.026 + 0.117 = 0.143\)

\(P(X \geq 2) = 1 - P(X < 2) = 1 - 0.143 = 0.857\)

0.857 = 85.7% probability that at least 2 of the rolls come up as a 3 or a 4.

Answer:

a = 6

b = 25

Step-by-step explanation:

As alternative angles in a parallel line are equal to each other,

5a = 3a + 12

So, now we can find the value of a by making "a" the subject.

5a - 3a = 12

2a = 12

Divide both sides by 2.

a = 6°

And now let us find the value of b.

We know that interior angles in a triangle are added up to 180°.

So,

2b + 4b + 3a + 12 = 180

We can replace a with 6 and then we can make "b" the subject to find the value of b.

Let us solve it now.

2b + 4b + 3 × 6 + 12 = 180

6b + 18 + 12 = 180

6b + 30 = 180

6b = 180 - 30

6b = 150

Divide both sides by 6.

b = 25°

What is volume?

A three-dimensional space's occupied volume is measured. It is frequently expressed as a numerical value using SI-derived units, different imperial units, or US customary units. Volume definition and length definition are related.

Given:

The bases of the solids are bounded by the circle x^2 + y^2 = 16.

(a) First to find the volume of square.

a. Volume

v = \(\int\limits^4_-_4\) 4(16 - x2)dx

 = 8(16x - x3/3)(0 to4 )

 = 8(64 - 64/3)

  = 1024/3.

b. Volume

v = \(\int\limits^4_-_4\)√3(16 - x2)dx

  = 2√3(16x - x3/3(0 to 4)

  = 2√3(64 - 64/3)

V = 256√3/3.

c. Volume

v = \(\int\limits^4_-_4\)π/2(16 - x2)dx

  = π(16x - x3/3)(0 to 4)

  = 128π/3

d. Volume

v = \(\int\limits^4_-_4\)2(16 - x2)dx

  = 4(16x - x3/3)(0 to 4)

V = 512/3

Hence,

(a) Volume of Square is 1024/3.

(b) Volume of equilateral triangle is 256√3/3.

Using the inverse of the function from the table, the value of f⁻¹(4) is 107/3

The inverse of a function is a new function that "undoes" the original function. It reverses the mapping of inputs and outputs, allowing you to find the original input value when you know the output value.

In this problem, we have to use the table to find the original function which is f(x) and use it to find the inverse of the function;

Taking two points from the table;

m = y₂ - y₁ / x₂ - x₁

m = 0 - (-3) / -9 - (-11)

m = 3 / 20

Using the slope and one point on the table;

y = mx + x

-3 = 3/20(-11) + c

-3 = -1.65 + c

c = -3 + 1.65

c = -1.35

Putting the slope and y - intercept together;

y = 3/20x - 1.35

y = 3/20x - 27/20

f(x) = 3/20x - 27/20

Taking the inverse of the function;

f⁻¹(x) = (20x + 27)/3

To find the value of f⁻¹(4), we just need to substituting the value of x in the function;

f⁻¹(4) = (20(4) + 27)/3

f⁻¹(4) = 107/3

The quadratic equation in standard form is:

ax^2 + bx + c = 25x^2 - 36x + 0

To factor this quadratic equation, we can first factor out the common factor of x:

25x^2 - 36x + 0 = x(25x - 36)

Now we can see that we have a quadratic expression inside the parentheses that can be factored further. To do so, we need to find two numbers whose product is 25 * (-36) = -900 and whose sum is -36. These numbers are -40 and 4:

25x^2 - 36x + 0 = x(25x - 36) = x(5x - 4)(5x - 32)

Therefore, the factored form of the quadratic equation is:

25x^2 - 36x + 0 = x(5x - 4)(5x - 32)

The function g(x) in the form a(x-h)^2 + k is: \(g(x) = (x + 2)^2 - 4\)

Starting with\(f(x) = x^2\), the translation 2 units left and 4 units down would result in the following transformation:

g(x) = f(x + 2) - 4

Substituting\(f(x) = x^2:\)

\(g(x) = (x + 2)^2 - 4\)

Expanding the square:

\(g(x) = x^2 + 4x + 4 - 4\)

Simplifying:

\(g(x) = x^2 + 4x\)

Now we need to rewrite this expression in the form \(a(x-h)^2 + k.\) To do this, we will complete the square:

\(g(x) = x^2 + 4x\\g(x) = (x^2 + 4x + 4) - 4\\g(x) = (x + 2)^2 - 4\)

Therefore, the function g(x) in the form a(x-h)^2 + k is:

\(g(x) = (x + 2)^2 - 4\)

Where a = 1, h = -2, and k = -4.

he two numbers that multiply to -35 and add to get -18 are -5 and 3.

To see why, you can use the factoring method. First, find two numbers that multiply to give you -35. The factors of -35 are -1, 1, -5, and 5. So, the two numbers that multiply to -35 are either -5 and 7 or 5 and -7.

Next, find which pair of numbers adds up to -18. It's clear that 5 and -7 add up to -2, so they don't work. However, if we choose -5 and 3, we get:

-5 + 3 = -2

So, -5 and 3 are the two numbers that multiply to -35 and add to -18.

The graph that represents the inequality 5y≤10 is plotted below.

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

The given inequality is 5y≤10.

In a graph of an inequality, the symbols (<,>) are represented using a dotted line and the symbols (≤,≥) are represented using a straight line.

So, the graph of inequality 5y≤10 will have a straight line.

Now, writing the inequality 5y≤10 in slope-intercept form y = mx + b -

5y = 10

5y = 0x + 10

Substituting the values of x and y with origin (0,0) -

5(0) = 0(0) + 10

0 = 10

Putting the inequality symbol back -

0 ≤ 10

Since, 0 ≤ 10 is true hence the shaded region of graph will cover the origin.

On solving 5y = 10  -

y = 2

Hence the points of the inequality will be (0,2).

Therefore, the graph for the inequality 5y≤10 is plotted.
