2.6 A printer can print 12 color pages in 3 minutes. How many color pages can the printer print in 9 minutes?

a. Present value of $400 per year for 14 years at 14%: $2,702.83
b. Present value of $200 per year for 7 years at 7%: $1,155.54
c. Present value of $400 per year for 7 years at 0%: $2,800
d. Present value of $400 per year for 14 years at 14% (annuity due): $2,943.07
  Present value of $200 per year for 7 years at 7% (annuity due): $1,233.24
  Present value of $400 per year for 7 years at 0% (annuity due): $2,800

To find the present values of the ordinary annuities, we can use the formula for the present value of an annuity:

PV = PMT * [(1 - (1 + r)^(-n)) / r]
Where:
PV = Present value
PMT = Payment per period
r = Interest rate per period
n = Number of periods

a. $400 per year for 14 years at 14%:
PV = $400 * [(1 - (1 + 0.14)^(-14)) / 0.14]

≈ $2,702.83

b. $200 per year for 7 years at 7%:
PV = $200 * [(1 - (1 + 0.07)^(-7)) / 0.07]

≈ $1,155.54

c. $400 per year for 7 years at 0%:
Since the interest rate is 0%, the present value is simply the total amount of payments over the 7 years:
PV = $400 * 7

= $2,800

d. Reworking previous parts assuming they are annuities due:
For annuities due, we need to adjust the formula by multiplying it by (1 + r):

a. Present value of $400 per year for 14 years at 14%:
PV = $400 * [(1 - (1 + 0.14)^(-14)) / 0.14] * (1 + 0.14)

≈ $2,943.07

b. Present value of $200 per year for 7 years at 7%:
PV = $200 * [(1 - (1 + 0.07)^(-7)) / 0.07] * (1 + 0.07)

≈ $1,233.24

c. Present value of $400 per year for 7 years at 0%:
Since the interest rate is 0%, the present value remains the same:
PV = $400 * 7

= $2,800

In conclusion:
a. Present value of $400 per year for 14 years at 14%: $2,702.83
b. Present value of $200 per year for 7 years at 7%: $1,155.54
c. Present value of $400 per year for 7 years at 0%: $2,800
d. Present value of $400 per year for 14 years at 14% (annuity due): $2,943.07
  Present value of $200 per year for 7 years at 7% (annuity due): $1,233.24
  Present value of $400 per year for 7 years at 0% (annuity due): $2,800

For this question we need to subtract and multiply the numbers. We know that 2 = 25% of 8 so:

\(\boxed{8-2=6}\\\boxed{6/2=3}\)

We are going to take that 25% and multiply it with 3 to get are final answer.

\(\boxed{25*3=75}\\\boxed{So,2=75}\)

Therefore, If the original quantity is 8 and the new quantity is 2, then the correct answer is 75%.

A company pays $5,000 for equipment. The book value of the equipment at the end of Year 2 will be $4,000.

The book value of an asset can be calculated by subtracting the accumulated depreciation from the initial cost of the asset.

Given:

Initial cost of the equipment = $5,000

Annual depreciation = $500

After Year 1, the accumulated depreciation would be $500.

So, the book value at the end of Year 1 would be:

Book value at the end of Year 1 = Initial cost - Accumulated depreciation

Book value at the end of Year 1 = $5,000 - $500 = $4,500

After Year 2, the accumulated depreciation would be $500 + $500 = $1,000 (since depreciation is $500 per year).

So, the book value at the end of Year 2 would be:

Book value at the end of Year 2 = Initial cost - Accumulated depreciation

Book value at the end of Year 2 = $5,000 - $1,000 = $4,000

Therefore, the book value of the equipment at the end of Year 2 is $4,000. Hence, the correct answer is option a. $4,000.

To prove the identity sinh(2x) = 2 sinh(x) cosh(x), we can use the definitions of sinh(x) and cosh(x) and apply trigonometric identities for exponential functions.

We start with the left-hand side of the identity, sinh(2x). Using the definition of the hyperbolic sine function, sinh(x) = (e^x - e^(-x))/2, we can substitute 2x for x in this expression, giving us sinh(2x) = (e^(2x) - e^(-2x))/2.

Next, we focus on the right-hand side of the identity, 2 sinh(x) cosh(x). Again using the definitions of sinh(x) and cosh(x), we have 2 sinh(x) cosh(x) = 2((e^x - e^(-x))/2)((e^x + e^(-x))/2).

Expanding this expression, we get 2 sinh(x) cosh(x) = (e^x - e^(-x))(e^x + e^(-x))/2.

By simplifying the right-hand side, we have (e^x * e^x - e^x * e^(-x) - e^(-x) * e^x + e^(-x) * e^(-x))/2.

This simplifies further to (e^(2x) - 1 + e^(-2x))/2, which is equal to the expression we derived for the left-hand side.

Hence, we have proved the identity sinh(2x) = 2 sinh(x) cosh(x) by showing that the left-hand side is equal to the right-hand side through the manipulation of the exponential functions.

Step-by-step explanation:

Let's assume the tree forms a right angle with the ground.

The distance from the tree to the man is 18 meters. The angle of elevation, which is 80 degrees, is the angle from where the man is to the top of the tree. We want to find the height of the tree, which we can call x.

Let's draw a diagram. (not to scale)

We can use sine (opposite/hypotenuse), cosine (adjacent/hypotenuse) or tangent (opposite/adjacent). We base the sides off of the elevation angle.

x is opposite the elevation angle and 18 is adjacent to the angle. So, we must use tangent.

\(tan(\theta)=opposite/adjacent\)

The angle (θ) is 80. The opposite is x. The adjacent is 18.

\(tan(80)=x/18\)

Now, solve for x by isolating it.

x is being divided by 18. The inverse of division is multiplication. Multiply both sides of the equation by 18.

\(18*tan(80)=x/18*18\)

\(18*tan(80)=x\)

\(18*5.67128182=x\)

\(102.0830728=x\)

Round to the nearest tenth. The 8 in the hundredth place tells us to round up.

\(102.1\approx x\)

The height of the tree is about 102.1 meters.

The costs and areas of the mat are

Represent the dimensions of the frame with

Length = x

Width = y

So, the frame area is

Area = xy

When the mat is 1 inch from the frame, we have

Whole Area = (x + 1 + 1) * (y + 1 + 1)

Whole Area = (x + 2) * (y + 2)

Expand

Whole Area = xy + 2x + 2y + 4

So, the mat area is

Mat area = xy + 2x + 2y + 4 - xy

Mat area = 2x + 2y + 4

The cost is

Cost = 0.05 * (2x + 2y + 4)

Cost = 0.1x + 0.1y + 0.2

When the mat is 2 inches from the frame, we have

Whole Area = (x + 4) * (y + 4)

Expand

Whole Area = xy + 4x + 4y + 16

So, the mat area is

Mat area = xy + 4x + 4y + 16 - xy

Mat area = 4x + 4y + 16

The cost is

Cost = 0.05 * (4x + 4y + 16)

Cost = 0.2x + 0.2y + 0.8

You can use scatter plots to present bivariate data. The data can be used to create coordinate pairs.

The relationship between the two variables in a bivariate data set is graphically represented by a scatter plot. Consider them to be the graphic depiction of two data sets that have been combined by allocating each axis in the plot to a distinct variable.

Due to the presence of two variables, this type of data is known as bivariate data. Only 1 variable may be displayed on a line plot. You can use scatter plots to present bivariate data. The data can be used to create coordinate pairs.

The standard deviation of each variable and the covariance between them must first be determined in order to calculate the Pearson correlation. Covariance is subtracted from the product of the standard deviations of the two variables to get the correlation coefficient.

The answer is "\(x(\frac{250}{3}-x)\)"

Step-by-step explanation:

Both points are similar that's why the solution is:

\(\to \frac{6x+6y=500}{6}\\\\\to x+y=\frac{250}{3}\\\\\to y= \frac{250}{3}-x \\\\\to Area= xy\\\\ \to Area= x(\frac{250}{3}-x)\)

We can evaluate the integral on the right side to find the particular solution for the given initial condition y(0) = 5.

(i) To determine if the given differential equation is linear, we need to check if the dependent variable y and its derivatives appear linearly (raised to the power of 1) and without any products or compositions. In the given differential equation dy/dx = e^(-x^2) (2x+1)sin(x) - 2xy, we can see that y and its derivative dy/dx appear linearly. Therefore, the given differential equation is linear.

(ii) In a linear first-order differential equation in the form dy/dx + p(x)y = q(x), the coefficient of y is denoted as p(x), and the right-hand side of the equation is denoted as q(x). Comparing this with the given differential equation dy/dx = e^(-x^2) (2x+1)sin(x) - 2xy, we can identify p(x) as -2x and q(x) as e^(-x^2) (2x+1)sin(x).

(iii) To find the particular solution given the initial condition y(0) = 5, we can solve the differential equation. Rearranging the given equation, we have:

dy/dx + 2xy = e^(-x^2) (2x+1)sin(x)

This is a linear first-order ordinary differential equation. We can solve it using an integrating factor. The integrating factor is given by the exponential of the integral of p(x) dx:

I(x) = e^(∫2x dx) = e^(x^2)

Multiplying the entire differential equation by the integrating factor, we get:

e^(x^2) dy/dx + 2xye^(x^2) = e^(-x^2) (2x+1)sin(x) e^(x^2)

Simplifying the left side using the product rule, we have:

d/dx (e^(x^2) y) = e^(-x^2) (2x+1)sin(x) e^(x^2)

Integrating both sides with respect to x, we obtain:

e^(x^2) y = ∫(e^(-x^2) (2x+1)sin(x) e^(x^2)) dx

The integral on the right side can be simplified as it cancels out the exponential terms:

e^(x^2) y = ∫(2x+1)sin(x) dx

Integrating the right side using integration techniques, we can find the antiderivative. Once we have the antiderivative, we divide both sides by e^(x^2) to isolate y:

y = (1/e^(x^2)) ∫(2x+1)sin(x) dx

Using numerical or numerical approximation methods, we can evaluate the integral on the right side to find the particular solution for the given initial condition y(0) = 5.

Let soft tacos be x

Let burritos be y

3x + 3y = 11.25 ......... i

4x + 2y = 10.00 ......... ii

Multiply equation I by 4

Multiply equation ii by 3

12x + 12y = 45 ....... iii

12x + 6y = 30 ....... iv

Subtract iv from iii

6y = 15

y = 15/6 = 2.5

A burrito cost $2.50

Since 3x + 3y = 11.25 .

3x + 3(2.50) = 11.25

3x + 7.50 = 11.25

3x = 11.25 - 7.50

3x = 3.75.

x = 3.75/3

x = $1.25

A soft tacos is $1.25
