Answer:

A is the answer :))))))))))))))))))

Step-by-step explanation:

The leading term is -5x^4, which tells us the highest degree of the polynomial.

The leading term in the equation tells us about the degree and whether the curve opens outwards on inwards

What is an equation in one variable?

An equation is a polynomial in one variable with a finite degree

We are given an equation

[tex]-5x^4+4x^3-6x^2+8[/tex]

In this the leading term is -5x^4

Here the coefficient is negative this tells us that the curve opens downwards. if the coefficient has been positive then the curve would open outwards.

Also from the leading term we can find out the degree of the highest variable. the degree of highest variable in this case is 4

Hence, The leading term in the equation tells us about the degree of the variable and whether the curve opens outwards on inwards

Given:

Angle A = 120 degrees

Side opposite angle C = 150 meters

Side opposite angle B = 275 meters

Find:

Angle B

Solution:

Since we have two sides given and an included angle, we can use cosine law.

Let's look for the length of the side opposite Angle A first.

where a = length of the side opposite Angle A or side BC

b = side opposite Angle B or Side AC

c = side opposite Angle C or Side AB

A = Angle A

Since we already have the data above, let's plug it in to the formula we have.

Then, solve a.

Hence, the length of side opposite a or Side BC is approximately 373.33 meters.

Now, to solve for Angle B, we can use the sine law.

Let's plug in the value of Angle A, side BC or a, and side AC or b to the formula.

Then, solve for Angle B.

Therefore, the bearing of ship C from ship B is approximately 40 degrees. (rounded off to the nearest degree)

The inverse of the function f(x) = 10 (√x + 9) is  f⁻¹(x) = (x - 90)² / 100

Given,

The function, f(x) = 10 (√x + 9)

We have to find the inverse of the function, f⁻¹(x)

Here,

f(x) = 10 (√x + 9)

f(x) = 10√x + 90

Replace f(x) with y.

y = 10√x + 90

Swap x with y;

x = 10√y + 90

Solve for y

That is,

x = 10√y + 90

x - 90 = 10√y

(x - 90) / 10 = √y

Square both sides

((x - 90) / 10)² = √y²

(x - 90)² / 100 = y

Replace y with f⁻¹(x)

That is,

f⁻¹(x) = (x - 90)² / 100

Therefore,

The inverse for the function  f(x) = 10 (√x + 9) is  f⁻¹(x) = (x - 90)² / 100

Expression given:

To know how to graph the given expression, it is easier if we determine what it means in words. In this case, this expression means all the values above one (without including one).

We know that one is not included as it has the sing ">", if the value were included, then it would have the sing "≥" or "≤".

This is important because when you are graphing, a discontinuous line is drawn for values not included, and a continuous one for included values.

Now, we would have to evaluate if it is the independent variable (generally called x), or the dependent variable (generally called y).

Assuming that g is the dependent variable, then the graph would be like this:

However, if the variable was de independent variable, then it would look like this:

We have to note that both graphs go from 1 to bigger values.

Let x be the number of children and let y be the number of adults.

We know that the total number of attendants was 147, then:

We also know that each child ticket cost $4 and for each adult cost $12, and the total amount collected were $1156. Then we have:

Hence we have the system:

Now we have to solve the system. To do that we solve the first equation for y:

and we plug this value into the second equation and solve for x:

Now that we have the value we can find the value of y, then:

Therefore there were 76 children and 71 adults.

The following congruence statements a, b, e, f are correct.

Triangle congruence: If all three corresponding sides and all three corresponding angles seem to be equal in size, two triangles are said to be congruent.

When two triangles are congruent, their sides and corresponding angles are identical.

Therefore, if GHI is congruent to LMN, then GH =LM, HI=MN and GI=LN, and also angle G=angle L, Angle H=angle M, while angle I = angle N, therefore the correct answers is f) ∠M= ∠H, (a) GH = LM b) ∠L=∠G. and e)IH=NM.

Therefore, option a, b, e, f are correct.

Answer:

  12.123

Step-by-step explanation:

You want the area under the curve f(x) = √(3x+5) on the interval [0, 4] estimated using the left sum and four subintervals.

When the interval [0, 4] is divided into four equal parts, each has unit width. That means the area of the rectangle defined by the curve and the interval width will be equal to the value of the curve at the left end of the interval.

The area we want is the sum ...

  f(0) +f(1) +f(2) +f(3)

As the attachment shows, that sum is ...

  area ≈ 12.123 . . . square units

Additional comment

The table values in the attachment are rounded to 7 decimal places. Trailing zeros are not shown. Actual values used have 12 significant digits, as the total shows.

Such a sum is called a Riemann sum, named for a German mathematician. Four such sums are commonly used, and further refinements are possible. Those are the left sum (as here), the right sum, the midpoint sum, and a sum using a trapezoidal approximation of the rectangle area.

For left, right, and midpoint sums, n function values are required for n subintervals. When the trapezoidal approximation is used, n+1 function values are required.

The probability that they are the 5 oldest people in the group is 1/6.

Given that we have a group of 6 people, and we randomly select 5 of them.

We need to find the probability that they are the 5 oldest people in the group.

The total number of ways to select 5 people from a group of 6 people is given by 6C5 which is equal to 6.

This means that there are only 6 possible outcomes when we randomly select 5 people from a group of 6 people.

We know that the 5 oldest people in the group can be selected only in one way.

So, the number of favorable outcomes is 1.

Hence, the probability of selecting the 5 oldest people from the group when 5 people are randomly selected is: Probability = favorable outcomes/total outcomes Probability = 1/6

Therefore, the probability that they are the 5 oldest people in the group is 1/6.

How to calculate percentage of a situation?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it. There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of anything, we mean that it is 50% of everything.
Formula for percentages: (Value/Total value) * 100

Given, amount invested in company A = $ 12,000
Amount invested in company B = $ 8000
Profit earned by company A = 14%
Profit earned by company B = 21%
Amount in profit earned from company A = (12000*14)/100 = $ 1680
Amount in profit earned from company B = (8000*21)/100 = $ 1680
Therefore total profit of the investment firm = $ (1680 + 1680) = $ 3360
Thus, the investment firm's total profit is $ 3360.
Now, percentage profit of total investment = (3360/20000)*100 = 16.8%, using available literature and formula.
Thus, the percent profit for their total investment is 16.8%
