The value of c is zero and a and b can be something else, because the vector are linearly independent.

A set of vectors is linearly independent if no vector can be expressed as a linear combination of the others (i.e., is in the span of the other vectors). A set of vectors is linearly independent if no vector can be expressed as a linear combination of those listed before it in the set.

Assume the following:

[tex]a\left[\begin{array}{ccc}2\\2\\0\end{array}\right] + b\left[\begin{array}{ccc}1\\-1\\1\end{array}\right] +c\left[\begin{array}{ccc}4\\2\\-2\end{array}\right] = \left[\begin{array}{ccc}0\\0\\0\end{array}\right][/tex]

Determine if a=b=c=0

[tex]2a+b+4c =0 (1)\\ 2a-b+2c =0 (2)\\b-2c=0(3)\\[/tex]

Subtract (2) from (1)

[tex]b+c = 0\\b-2c=0[/tex]

Substitute (5) into (4), we get c=0.

Correct option is C, A triangle can be formed with these side lengths since 8 cm, which is greater than the third side's 7 cm, is possible.

A right triangle's hypotenuse is its longest side, its "opposite" side is the one that faces a certain angle, and its "adjacent" side is the one that faces the angle in question. To describe the sides of right triangles, we utilize specific terminology.

Straight angle refers to the angle that is 180 degrees in length.

The side length combinations that can result in a triangle include

2, 7, and 6 centimeters; 2 meters; 5, and 7 meters

6, 6, and 12 feet

According to the triangle inequality theorem, the third side of a triangle is greater than or equal to the sum of any two of its sides.

In other words, in a triangle with sides a, b, and c,

a + b ≥ c

When examining the sets of provided side lengths,

2 cm, 7 cm, and 6 cm in a triangle,

2 + 6 = 8,

Thus, a triangle can be formed with these side lengths since 8 cm, which is greater than the third side's 7 cm, is possible.

The car loses all of its marketable value after 9 years, the x-intercepts represent the points at which the car has lost all of its value, so they are (9, 0) and (0, 22995).

The depreciation equation for the car can be represented as y = mx + b, where y is the value of the car at time x, m is the slope of the line, and b is the y-intercept.

To find the slope, we can use the information that the car loses all of its marketable value after 9 years. The market value of the car will be 0 after 9 years, so we can set y = 0 when x = 9:

0 = m * 9 + b

To find the y-intercept, we can use the information that Jason purchased the car for $22,995. This means that the value of the car at time 0 was $22,995, so we can set y = 22,995 and x = 0:

22,995 = m * 0 + b

Combining these two equations, we can solve for m and b:

0 = m * 9 + b

22,995 = m * 0 + b

b = 22,995

Now that we have found the y-intercept, we can use it to find the x-intercepts by setting y = 0 and solving for x:

0 = m * x + 22,995

0 - 22,995 = m * x

-22,995 = m * x

x = -22,995 / m

Since we don't know the value of m, we can't find the x-intercepts directly. However, since the car loses all of its marketable value after 9 years, the x-intercepts represent the points at which the car has lost all of its value, so they are (9, 0) and (0, 22995).

The two equations, y = 53x + 10 and y = 55x, represent the cost of x tickets for option 1 and option 2, respectively.

The equation y = 53x + 10 represents the cost of x tickets for option 1, which includes a ticket cost of $53 per ticket plus a shipping fee of $10. So, if Mrs. Curtis buys 1 ticket, the cost would be 53 * 1 + 10 = 63. If she buys 2 tickets, the cost would be 53 * 2 + 10 = 116, and so on.

The equation y = 55x represents the cost of x tickets for option 2, which includes a ticket cost of $55 per ticket and free shipping. So, if Mrs. Curtis buys 1 ticket, the cost would be 55 * 1 = 55. If she buys 2 tickets, the cost would be 55 * 2 = 110, and so on.

Tthe the number of smallmouth bass Chelsie caught = 37

and the number of salmon she caught = 15

Here, x represents the number of smallmouth bass Chelsie caught. and y represents the number of salmon she caught.

Chelsie caught 52 fish today.

So we get an equation,

x + y = 52        

Also, for smallmouth bass, she caught seven more than 2 times the amount of salmon she caught.

So we get an equation,

x = 7 + 2y  

So, we get a system of equations:

x + y = 52                      ..........(1)

x = 7 + 2y                .......(2)

Substitute above value of x in equation (1)

(7 + 2y) + y = 52      

7 + 3y = 52

3y = 45

y = 15

Substitute above value of y in equation (2),

x = 7 + 2(15)

x = 37

Therefore, she caught 37 smallmouth bass and 15 salmon.

The solution to the system of equations 4a + 3b = -9 and 2a + 5b = -1 is a = 12, b = -5, found through substitution method.

Simultaneous equations are a set of equations with multiple variables, and the solution of these equations gives us the values of the variables that make all the equations true at the same time. To solve these equations, we can use elimination, substitution or matrices method.

Here, the given set of simultaneous equations is

4a + 3b = -9

2a + 5b = -1

One way to solve this is by substitution, where we solve one equation for one variable and substitute that expression into the other equation. Solving the first equation for "a", we get:

a = -3b - 3

Substituting this expression into the second equation, we get:

2(-3b - 3) + 5b = -1

Expanding the left-hand side, we get:

-6b - 6 + 5b = -1

Combining the like terms, we get:

-b - 6 = -1

Adding b and 6 to both sides, we get:

-b = 5

Finally, dividing both sides by -1, we get:

b = -5

Substituting the value of b back into the expression for a, we get:

a = -3(-5) - 3 = 15 - 3 = 12

So the solution to the system of equations is:

"a" can be expressed as a function of "R" as:

[tex]a = 10^{\frac{(R - 15)}{3} - 2}[/tex].

What are logarithmic properties?

The 4 laws of logarithms are product property, division property, power property and change of base property.

To solve for "a" in terms of "R," we need to isolate "a" on one side of the equation. We can do this by rearranging the equation and applying logarithmic properties.

Starting with the equation R = 3 log(a + 2) + 15, we'll subtract 15 from both sides:

R - 15 = 3 log(a + 2)

Next, we'll divide both sides by 3:

(R - 15) / 3 = log(a + 2)

Finally, we'll use the inverse logarithmic function, denoted as "exp" or "10^," to solve for "a":

[tex]a+2 = 10^{\frac{(R - 15)}{3} }[/tex]

And finally, we'll subtract 2 from both sides to obtain the solution:

[tex]a = 10^{\frac{(R - 15)}{3} - 2}[/tex]

So, "a" can be expressed as a function of "R" as:

[tex]a = 10^{\frac{(R - 15)}{3} - 2}[/tex]

When the variance of the error term increases in a simple linear regression model, it indicates a less accurate model with a high degree of uncertainty in its predictions.

Regression is a statistical method used to model the relationship between two variables, where one of the variables is dependent on the other.

Simple linear regression is a type of regression where the relationship between the dependent variable and the independent variable is modeled as a linear equation.

Mathematically, let's consider the simple linear regression equation as:

Y = β0 + β1X + ε

Where Y is the dependent variable, X is the independent variable, β0 and β1 are the coefficients of the regression equation, and ε is the error term.

The variance of the error term, Var(ε), is a measure of the spread of the residuals. A large variance of the error term indicates that the residuals are spread out over a large range, and thus, the regression model's predictions may not be very accurate.

In other words, a large variance of the error term means that the model has a high degree of uncertainty in its predictions, leading to a larger deviation between the actual and predicted values.
