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,

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

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

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

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)

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

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.

Area overall is 392 square metres. The two lawns' combined area is therefore 392 square metres.

A square is a quadrilateral in geometry that has four equal sides and four right angles (90-degree angles). It is a unique kind of both a rhombus and a rectangle. A square is made up of four equal-length sides, two equal-length diagonals, and right-angle diagonal cuts. A square's area and perimeter can be calculated by multiplying one of its sides by itself (squared), and one of its sides by four, respectively. Because of their symmetry and regularity, squares are frequently employed in mathematics and building.

By multiplying the first lawn's length by its breadth, one may determine its area: 56 square metres is the size of the first lawn, which is 8 metres by 7 metres.

The second lawn's breadth is six times that of the first lawn's, so:

The second lawn's width is equal to 6 × 7 metres, or 42 metres.

The second lawn is the same length as the first one, so:

The second lawn is 8 metres long.

The second lawn's area is calculated by multiplying its length by its width:

The second lawn is 336 square metres in size (8 metres by 42 metres).

The first and second lawns' combined areas make up the overall area of the two lawns:

Total area equals the sum of the first and second lawns.

56 square metres + 336 square metres make up the total area.

Area overall is 392 square metres. The two lawns' combined area is therefore 392 square metres.

= (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%.

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

To simplify the expression above, simply combine similar terms.

The similar terms in the expression above are 8c and -3c as well as 6 and -2.

Let's combine the pairs of similar terms.

So, 8c - 3c = 5c and 6 - 2 = 4. Hence, the answer is:
