The annual fixed expense for car insurance is  $ 1,046.70.

It is given in the question that John makes six payments in a year at $174.45 each.

We have to find the annual fixed expense for car insurance.

We know that,

The annual fixed expense for the car insurance will be 6 times the individual payment given in the question.

Hence, by simple multiplication, we can write,

Annual fixed expense for the car insurance = 6*174.45 = $ 1,046.70

Car insurance

Car insurance is a type of financial protection that covers the cost of another driver’s medical bills and repairs if you cause an accident with your car, or in case your car is stolen or damaged some other way.

So answer is 7.

In order to find the value of f(1.2), we just need to find the value of f(x) in the graph that corresponds to x = 1.2.

Looking at the graph, when x = 1.2, the function f(x) is equal to 2.

Then, to find the largest value of x for which f(x) = 1.5, we look for the value 1.5 in the vertical axis, then find the corresponding value of x.

For this value, we have two possible values of x: 1.2 and 3.6.

So the largest value is x = 3.6

Answer:

Step-by-step explanation:

The value of the composition (g ° f) (x) between the linear equation g(x) and the quadratic equation f(x) evaluated at x = 5 is equal to 6.

In this problem we find a quadratic equation f(x) and a linear equation g(x), of which we must derive a composition consisting in substituting the input variable of the linear equation with the quadratic equation. Later, we evaluate the resulting expression at x = 5.  

Now we present the complete procedure:

(g ° f) (x) = - 2 · (x² - 6 · x + 2)

(g ° f) (x) = - 2 · x² + 12 · x - 4

(g ° f) (5) = - 2 · 5² + 12 · 5 - 4

(g ° f) (5) = - 50 + 60 - 4

(g ° f) (5) = 6

Equation for a rational function is 10(x2 + 7x + 12) / (x2 + 11x + 30) = 0.

What is Rational Function?

Any function that can be expressed mathematically as a rational fraction—an algebraic fraction in which both the numerator and the denominator are polynomials—is referred to as a rational function. The polynomials' coefficients don't have to be rational numbers; they can be found in any field K.

So this will be a rational function with the vertical asymptotes given by the denominators:

(x + 5) and (x + 6).

The x-intercepts will be provided by the numerator,

which will be:

a(x + 3)(x + 4)

The letter an is a constant.

Given that (0,4) is the y intercept, we have:

4 = a(0+3)(0+4) / (0+5)(0+6)

4= 12a / 30

12a = 120

now,

a = 120/12,

a = 10,

and a = 1.

Now,

a(x+3)(x+4) / (x+5)(x+6) = 0

10 (x^2 + 7x + 12) / (x^2 + 11x + 30) = 0

Hence, We have the following equation for a rational function:

10 (x2 + 7x + 12) / (x2 + 11x + 30) = 0.

Given;

We are given the step by step procedure to find the height of a triangle.

Required;

We are required to determine if the step by step solution is true or false.

Solution/Explanation;

When finding the height of a triangle, we may use the Pythagoras theorem or we may use trigonometric ratios for right angled triangles.

Note that the Pythagoras' theorem is also used only for right angled triangles and one of the three sides will be the height of the triangle.

When required to calculate the the height of a triangle given a line perpendicular to the base (that is, at a 90 degree angle with the base), and passing through the vertex opposite the base, the triangle can be effectively split into two parts along the perpendicular and the perpendicular line will then become the height. Also depending on the amount of information available, we may use the Pythagoras' theorem (if the other two sides are given). Alternatively we may use the trigonometric ratios if one other side and one of the angles is given.

First, we do completing the square on the given function to express it into vertex form. So,

We write it in the form:

And, factor out 3: So,

Since:

Then,

Therefore, the answer is:

We have here a special case where the line is vertical. In this case, the line has an "infinite" slope (or it is not defined). Therefore, since the line is vertical and contains the point (10, 14), the line is given by the equation:

The standard form of the line is given by the general equation:

Then, we can rewrite the equation as follows:

We can see that this line contains the point (10,14):

We can see that the vertical line, x + 0y = 10 passes through the point (10, 14).

In summary, the line is given by x + 0y = 10 (A = 1, B = 0, C = 10).

Answer:

DJ = 24

Explanation:

We are told from the question that J is the centroid of CDE, this means that J is the midpoint of DH, CJ and FE

If J is the centroid of DH, then 2DJ = JH

Also DJ + JH = DH

The equation becomes:

DJ + 2DJ = DH

3DJ= DH

Given

DH = 72

Hence 3DJ = 72

DJ = 72/3

DJ = 24

Hence the measure of DJ is 24

The two composite functions have their values to be (w o s)(x) = 7x² - 49x + 33 and (s o w)(x) = (7x - 2)² - 7(7x - 2) + 5

Composite function 1

The given parameters are

w(x) = 7x - 2

s(x) = x² - 7x + 5

To calculate (w o s)(x), we make use of

(w o s)(x) = w(s(x))

So, we have

(w o s)(x) = 7s(x) - 2

Substitute s(x) = x² - 7x + 5

(w o s)(x) = 7(x² - 7x + 5) - 2

Expand

(w o s)(x) = 7x² - 49x + 35 - 2

Simplify

(w o s)(x) = 7x² - 49x + 33

Composite function 2

Here, we have

w(x) = 7x - 2

s(x) = x² - 7x + 5

To calculate (s o w)(x), we make use of

(s o w)(x) = s(w(x))

So, we have:

(s o w)(x) = w(x)² - 7w(x) + 5

Substitute w(x) = 7x - 2

(s o w)(x) = (7x - 2)² - 7(7x - 2) + 5

So, the composite functions are (w o s)(x) = 7x² - 49x + 33 and (s o w)(x) = (7x - 2)² - 7(7x - 2) + 5
