Yes, the given figure has the horizontal symmetry.

Line symmetry is a type of symmetry about reflections. When there is at least one line in an object that divides a figure into two halves such that one-half is the mirror image of the other half, it is known as line symmetry or reflection symmetry. The line of symmetry can be in any direction - horizontal, vertical, slanting, diagonal, etc.

The horizontal line of symmetry divides a shape into identical halves, when split horizontally, i.e., cut from right to left or vice-versa.

ANSWER

Let x = liters of drink A

Let y = liters of drink B

System:

EXPLANATION

We know that of the liters of drink A, 20% is real juice: 0.2x

and that of the liters of drink B, 15% is real juice: 0.15y

The sum of the amounts of real juice in each drink is 100.5, because it is said that 100.5 liters of real juice are use to make both drinks.

Also it is said that they make 30 more liters of drink A than of drink B, so the liters of drink A are 30 more than drink B: x = y + 30

The system is:

A composite number is defined as a whole number that have more than two factors; from this definition we conclude that all whole numbers that are not prime are composite numbers.

Since all even numbers are not prime we conclude that Larry is correct; all numbers that have a 2 in the one's place are composite. In fact all even numbers are composite with exception of 2 itself.

Answer:

There are 126 months in 10 years and 6 months.

Explanation:

In a year there are 12 months.

Then, to know how many months are in 10 years, we multiply by 10:

Now we add the additional 6 months:

The answer is 126.

Two lines are parallel is they have the same slope. In this case:

Solving the equation for y, and obtaining the slope-intercept equation for the line equation, we have:

Then,

a) The yield to maturity of the IOU Corporation's bond is -0.39%.

b) The current yield of the IOU Corporation's bond is 5.58%.

The bond's yield to maturity (YTM) is the total rate of return earned by a bondholder with all interest payments and the original principal repaid.

We can compute the yield to maturity using the following YTM formula:

Yield to Maturity = [Annual Interest + {(FV-Price)/Maturity}] / [(FV+Price)/2]

Where:

FV = Face Value of the Bond

Price = Current Market Price

Maturity = Maturity Period.

Bond's face value = $2,000

Current date = April 19, 2021.

Company (Ticker)  Coupon  Maturity  Last Price  Last Yield  EST volume

                                                                                                      (000s)

IOU            (IOU)       6.3    April 19, 2037  112.97         ??            1,857

Annual interest = $126 ($2,000 x 6.3%)

Maturity period = 16 (2037 - 2021)

Price = $2,259.4 ($2,000 x 112.97/100)

Yield to Maturity = [Annual Interest + {(FV-Price)/Maturity}] / [(FV+Price)/2]

= [$126 + {($2,000 - $2,259.4)/16}] / [($2,000 + 2,259.4)/2]

=  [$126 -$259.4)/16] / [($4,259.4)/2]

= -8.3375/2,129.7

= -0.39%

Current yield = Annual Coupon/Current Price

= 5.58% ($126/$2,259.4 x 100)

Given: the dimensions of the rectangular prism is 14 x 12 x 28 in cm

Answer:

-54

Step-by-step explanation:

Finding a value means you will get a number answer. Since they said x

x = -2

fill in -2 in place of the x.

also they said

y = 6

so fill in 6 wherever you see a y.

2(3x - 6) - 5y

fill in -2 for x and 6 for y.

= 2(3•-2 - 6) - 5•6

Work on parentheses first. Multiply before adding or subtracting.

= 2(-6 - 6) - 5•6

= 2(-12) - 5•6

Again, multiply before adding or subtracting.

= -24 - 30

= -54

The values for the composition of the functions are:

(f o g)(x) = 9x² + 5

(g o f)(x) = 3x² + 15

To evaluate the composition of a function, the first thing to do is to evaluate the inner function, then use the output as an input to evaluate the outer function of the composition.

Given the following functions:

f(x) = x² + 5

g(x) = 3x

We are required to find (f o g)(x) and (g o f)(x).

To find (f o g)(x), replace g(x) for x in the outer function f(x):

(f o g)(x) = (3x)² + 5

(f o g)(x) = 9x² + 5

To find (g o f)(x), replace f(x) for x in the outer function g(x):

(g o f)(x) = 3(x² + 5)

(g o f)(x) = 3x² + 15

Answer:

Volume = 2268 ft³

1814.4 bushels of corn

Explanation:

The volume of the corn crib can be calculated as:

Volume = Length x Width x Height

Then, the volume is equal to:

Volume = 21 ft x 9 ft x 12 ft

Volume = 2268 ft³

Finally, to know the number of bushels of corn that can be stored, we need to divide the volume of the corn crib by the volume of each bushel of corn. So:

Therefore, the volume of the corn crib is 2268 ft³ and it can store 1814.4 bushels of corn.

Based on the increase in CPI, the amount that would be required at year end to have the same purchasing power at the beginning of the year is $1,024.46.

First, find the inflation rate:

= (Current CPI - Beginning CPI) / Beginning CPI

= (108.9 - 106.3) / 106.3

= 2.446%

This means that the amount of money at the beginning of the year has lost a value of 2.446%.

In order to remain the same as the value of $1,000, a person would need:

= 1,000 x (1 + 2.446%)

8A) Let x represent the number of hours of horseback riding.

Let y represent the total cost of the package

If Lucky horseshoe stables is used for x hours, the equation for the total cost would be

y = 7x + 12

If Go galloping horseshoe rides is used for x hours, the equation for the total cost would be

y = 10x + 6

Thus, the equations are

y = 7x + 12

y = 10x + 6

B) To solve the system of equations, we would substitute the first equation into the second equation. It becomes

7x + 12 = 10x + 6

10x - 7x = 12 - 6

3x = 6

x = 6/3

x = 2

y = 7x + 12 = 7 * 2 + 12

y = 14 + 12

y = 26

The solution of the system of equations is (2, 26)

Standard deviation is an important measure of spread or dispersion. It tells us how far, on average the results are from the mean.

The smallest standard deviation belongs to the dataset with the smallest range and almost no outliers. Closer the values are to the mean, less the value of the standard deviation.

Comparing those datasets, the one that fits this description is the third one.

The number of solutions that this equation have is: A. zero solutions.

Generally speaking, an equation is said to have zero solution or no solution when the left hand side and right hand side of the equation are not the same or equal. This ultimately implies that, an equation would have zero solution or no solution when both sides of the equal sign are not the same and the variables cancel out.

In order to determine the number of solutions that this equation have, we would simplify the equation by opening the bracket and then compare both sides of the equation as follows:

6(c+4) = 6c + 30

6c + 24 = 6c + 30

6c - 6c = 30 - 24

Internal angles of a polygon

The triangle has n=3 sides, and the sum of its internal angles is 180°

The rectangle has n=4 sides, and the sumo of its internal angles is 360°

There is a general formula to calculate the sum of the internal angles of any polygon of n sides:

Sum = 180° ( n -2 )

For a pentagon (n=5), the sum of angles is:

Sum = 180° ( 5 -2 ) = 180° * 3 = 540°

We are required to find the measure of each internal angle. Since the pentagon is regular, all of its internal angles measure the same, thus:

The measure of each angle = 540° / 5 = 108°

The coordinates of a point on a circle with radius 18 corresponding to an angle of 190° are (-17.73, -3.13).

What is transforming coordinates?

Polar coordinates (r,θ) are transformed into Cartesian coordinates (x, y) using the formulas x = r cos(θ), and y = r sin(θ).

This problem is under the concept of transforming polar coordinates (r,θ) to cartesian coordinates  (x, y).

For this problem the polar coordinates  are r = 18 and θ = 190°.

Convert these polar coordinates into a cartesian coordinates as,

x = r cos(θ) = 18 cos(190°) = -17.73

y = r sin(θ) = 18 sin(190°) = -3.13
