3. Solving 13x² - 7 = 62

  - Subtract 62 from both sides: 13x^2 - 7 - 62 = 62 - 62

  - Simplify  -  13x² - 7 - 62 = 0

  - Combine like terms: 13x² - 69 = 0

  - Now, we can solve this quadratic equation using the square root method or factoring. Let's use the square root method

  - Add 69 to both sides: 13x² = 69

  - Divide both sides by 13: x² = 69/13

  - Take the square root of both sides: √(x²) = ±√(69/13)

  - Simplify: x = ±√(69/13)

4. Solving x² + 2x - 24 = 0  -

  - To solve this quadratic equation, let's factor it

  - Find two numbers that multiply to give -24 and add up to 2. The numbers are 6 and -4.

  - Rewrite the middle term  - x² + 6x - 4x - 24 = 0

  - Group the terms and factor by grouping: (x² + 6x) + (-4x - 24) = 0

  - Factor out the common terms: x(x + 6) - 4(x + 6) = 0

  - Combine like terms: (x - 4)(x + 6) = 0

  - Now, set each factor equal to zero and solve for x   -

    - x - 4 = 0; x = 4

    - x + 6 = 0; x = -6

So, the solutions for equation 3 are x = ±√(69/13), and the solutions for equation 4 are x = 4 and x = -6.

In summary, fy(a,b) is the slope of the tangent line to the surface defined by f(x, y) at the point (a, b) in the y-direction.

The given expression represents the partial derivative of f(x, y) with respect to y, evaluated at (a, b):

fy(a,b) = lim┬(y→b)⁡〖[f(a,y) - f(a,b)]/(y - b)〗

Geometrically, this partial derivative represents the slope of the tangent line to the surface defined by f(x, y) at the point (a, b) in the y-direction.

To see why this is the case, consider the following argument:

Let L be the limit in the expression given above.

Let h = y - b be the change in the y-coordinate from b to y.

Then, we can rewrite the limit as:

fy(a,b) = lim┬(h→0)⁡〖[f(a,b + h) - f(a,b)]/h〗

This expression represents the average rate of change of f(x, y) with respect to y over the interval [b, b + h].

As h approaches 0, this average rate of change approaches the instantaneous rate of change, which is the slope of the tangent line to the surface defined by f(x, y) at the point (a, b) in the y-direction.

Therefore, fy(a,b) is the partial derivative of f(x, y) with respect to y, evaluated at (a, b).

The surface area of the cylinder, given h = 6 feet and r = 2 feet, is approximately 100.8 square feet.

To find the surface area of a cylinder using the formula 2πr(r + h), we substitute the given values of h = 6 feet and r = 2 feet into the formula.

Surface Area = 2πr(r + h)

Surface Area = 2 * 3.14 * 2(2 + 6)

Surface Area = 2 * 3.14 * 2 * 8

Surface Area = 100.48 square feet (rounded to the nearest tenth)

Therefore, the surface area of the cylinder, with h = 6 feet and r = 2 feet, is approximately 100.8 square feet.

In the calculation, we first compute the value inside the parentheses, which is (2 + 6) = 8. Then, we multiply this value by 2πr, where r = 2. Finally, we round the result to the nearest tenth.

It's worth noting that in the given options, the closest answer to the calculated surface area of 100.8 square feet is option (a) 100.8 square feet.

Therefore, the center of pressure on the triangular sail is approximately (1.2, 0.9).

The center of pressure on a boat's sail that occupies a region R in the plane is given by

x = ∬R xydA/∬R ydA` and y = ∬R x²ydA/∬R xydA`.

To calculate the center of pressure on a triangular sail with vertices (0,0),(3,2) and (0,7) we will use the following formulas:

x = ∬R xydA/∬R ydA

y = ∬R x²ydA/∬R xydA

Remember that in this case, the region R in the plane is the triangular sail with vertices (0,0), (3,2), and (0,7).

Hence, the equations for x-bar and y-bar are:x-bar = ∬R xydA/∬R ydA= ∫(x=0 to x=3) ∫(y=0 to y=(7x/3))

=  xy dy dx/ ∫(x=0 to x=3) ∫(y=0 to y=(7x/3)) y dy dx= 42/35= 1.2 units (approx)

And,y-bar = ∬R x²ydA/∬R xydA= ∫(x=0 to x=3) ∫(y=0 to y=(7x/3)) x²y dy dx/ ∫(x=0 to x=3) ∫(y=0 to y=(7x/3)) xy dy dx= 63/70= 0.9 units (approx)

The integral of the function f(x, y) = 1/ln(x) over the given region is equal to 2. To integrate the function f(x,y) = 1/ln x over the given region, we need to set up a double integral.

First, let's find the limits of integration. The region is bounded by the x-axis, line x=3 and curve y=ln x. So, we can integrate with respect to x from 1 to 3 and with respect to y from 0 to ln 3.

Thus, the double integral is:

∫∫R (1/ln x) dy dx

Where R is the region bounded by the x-axis, line x=3 and curve y=ln x.

We can integrate this by reversing the order of integration and using u-substitution:

∫∫R (1/ln x) dy dx = ∫0^ln3 ∫1^e^y (1/ln x) dx dy

Let u = ln x, then du = (1/x) dx.

Substituting for dx, we get:

∫0^ln3 ∫ln1^ln3 (1/u) du dy

Integrating with respect to u, we get:

∫0^ln3 [ln(ln x)] ln3 dy

Finally, integrating with respect to y, we get:

[ln(ln x)] ln3 (ln 3 - 0) = ln(ln 3) ln3

Therefore, the value of the double integral is ln(ln 3) ln3.
To integrate the function f(x, y) = 1/ln(x) over the given region bounded by the x-axis (y=0), the line x=3, and the curve y=ln(x), we will set up a double integral.

The integral can be expressed as:

∬R (1/ln(x)) dA,

where R is the region defined by the given boundaries. We can use the vertical slice method for this problem, with x ranging from 1 to 3 and y ranging from 0 to ln(x):

∫(from x=1 to x=3) ∫(from y=0 to y=ln(x)) (1/ln(x)) dy dx.

First, integrate with respect to y:

∫(from x=1 to x=3) [(1/ln(x)) * y] (evaluated from y=0 to y=ln(x)) dx.

This simplifies to:

∫(from x=1 to x=3) (ln(x)/ln(x)) dx.

Now integrate with respect to x:

∫(from x=1 to x=3) dx.

Evaluating the integral gives:

[x] (evaluated from x=1 to x=3) = (3 - 1) = 2.

So, the integral of the function f(x, y) = 1/ln(x) over the given region is equal to 2.

The statement about regression line that is true is "it indicates a linear relationship between dependent variable and independent variable(s)."

In statistics, regression is a method of modeling the connection between a dependent variable (also known as a response variable) and one or more independent variables (also known as explanatory variables or predictors). It's also known as a linear regression model.

A regression model is established in order to identify the linear relationship between the dependent variable and one or more independent variables. The line of best fit is represented by the regression line in a simple linear regression model, which represents the relationship between the dependent variable and independent variable(s).

The line of best fit is determined by minimizing the sum of the squares of the residuals (errors). The objective of the regression model is to obtain a relationship between the dependent variable and the independent variable that explains the variance of the dependent variable based on the independent variable(s).

Hence, the correct option is: it indicates a linear relationship between dependent variable and independent variable(s).

To answer this question, we need to find a number that is a factor of 10^8. One way to approach this is to look at the prime factorization of 10^8, which is 2^8 * 5^8. If we want to divide this number by a factor to get the same answer, we can cancel out one or more of the factors of 2 and 5. For example, if we divide by 2^4 * 5^4, we will be left with 2^4 * 5^4, which is the same as (10^4)^2. Therefore, we can divide 10^8 by 10^4 to get the same answer. Another way to think about it is to note that dividing by 10^4 is the same as moving the decimal point four places to the left, which makes sense since 10^8 has eight digits and dividing by 10^4 leaves us with only four digits.

To divide 10^8 by a number and get the same result, you should divide it by 1. This is because any number divided by 1 will yield the same number as the result. In mathematical terms, 10^8 ÷ 1 = 10^8. The number 1 is known as the multiplicative identity, as it doesn't change the value of a number when multiplied or divided by it. Therefore, dividing 10^8 by 1 gives you the same answer, which is 10^8.

The solution for the system of equations: y = 3 - 2x and y = 8 - 7x, is x = 1, y = 1.

In the question, we are given a system of equations,

y = 3 -2x ... (i), and

y = 8 - 7x ... (ii).

We have been asked to solve the given system of equations.

To solve the system of equations, we do as follows:

Substitute the value of y = 3 - 2x, from (i) in (ii), to get:

y = 8 - 7x,

or, 3 - 2x = 8 - 7x, which is a linear equation in one variable.

To solve this, we follow these steps:

3 - 2x = 8 - 7x,

or, 3 - 2x + 7x = 8 - 7x + 7x {Adding 7x to both side of the equation},

or, 3 + 5x = 8 {Simplifying},

or, 3 + 5x - 3 = 8 - 3 {Subtracting 3 from both sides of the equation},

or, 5x = 5 {Simplifying},

or, 5x/5 = 5/5 {Dividing both sides of the equation by 5},

or, x = 1.

Substituting x = 1, in (i), we get:

y = 3 - 2x,

or, y = 3 - 2(1),

or, y = 3 - 2 = 1.

Thus, the solution for the system of equations: y = 3 - 2x and y = 8 - 7x, is x = 1, y = 1.

After an hour, the percentage of alcohol in the vat is approximately 4.92%.

After an hour of pumping beer with 6% alcohol into the vat at a rate of 5 gallons per minute and simultaneously pumping the mixture out at the same rate, the percentage of alcohol in the vat can be calculated as follows:

Initially, the vat has 500 gallons of beer with 4% alcohol content. This means there are 20 gallons of alcohol in the vat (500 * 0.04).

Now, let's consider the beer being pumped in at a rate of 5 gallons per minute with a 6% alcohol content. Over the course of an hour (60 minutes), this amounts to 300 gallons of beer, containing 18 gallons of alcohol (300 * 0.06).

As the mixture is being pumped out at the same rate, only 500 gallons of beer remain in the vat after an hour. The total alcohol in the vat is the sum of the alcohol from the initial beer and the pumped-in beer, minus the amount of alcohol pumped out. The mixture pumped out contains the same proportion of alcohol as the mixture in the vat, so it amounts to (5 gallons/minute * 60 minutes) * X%, where X% is the percentage of alcohol in the mixture at the end of an hour.

To find X%, we can set up the following equation:

20 (initial alcohol) + 18 (alcohol pumped in) - 5 * 60 * X% = 500 * X%

Solving for X, we get:

38 - 300 * X% = 500 * X%

Rearranging and solving for X, we find that:

X% ≈ 4.92%

  We will set up a coordinate system with the x-axis along the line of scrimmage pointing to the right, and the y-axis pointing downfield.

ii. Represent each step in ball motion by a displacement vector in your graph:

  Step 1: The quarterback runs backward for 10 yards. This can be represented by a vector pointing in the negative y-direction with a magnitude of 10 yards.

  Step 2: The quarterback runs sideways to the left, parallel to the line of scrimmage, for 15 yards. This can be represented by a vector pointing in the negative x-direction with a magnitude of 15 yards.

  Step 3: The forward pass is thrown at an angle of 60 degrees with respect to the line of scrimmage to the right. The ball flies 50 yards in this direction. This can be represented by a vector with a magnitude of 50 yards at an angle of 60 degrees from the positive x-axis.

iii. Write down x and y components of each vector:

  Step 1:

  - Displacement vector: (-15, -10) yards

  Step 2:

  - Displacement vector: (-15, 0) yards

  Step 3:

  - Displacement vector: (50 * cos(60), 50 * sin(60)) yards

  - Displacement vector: (25, 43.3) yards (approximately)

iv. Add components up to obtain components of the total displacement:

  To find the total displacement, we need to sum up the x and y components of all the displacement vectors.

  Total x-component: -15 + (-15) + 25 = -5 yards

  Total y-component: -10 + 0 + 43.3 = 33.3 yards (approximately)

v. Calculate magnitude of the total displacement vector:
