Answer:

Isabella spent $1302.52 and Jesus spent $1740.99.

Step-by-step explanation:

In order to figure out how much each individual person spent, we need to write a mathematical equation to express this situation. An equation in math is a statement that relates two expressions that are equal in value, and can be used to solve for variables. A linear equation with one variable is often presented in is standard form, [tex]ax+b=0[/tex].

In this case, we can represent the amount that Isabella spent with the variable x. Since Jesus spent $438.47 more than Isabella, this amount can be represented with x + 438.47. We can set up our equation as follows:

[tex]x+(438.47+x)=3043.51[/tex]

*Note that the use of parentheses is not necessary but may be useful in making your work clearer!

To solve for x, we should combine like terms and then move the variables to one side and constants to the other. The variable can be isolated by subtracting 438.47 from 3043.51:

Now that we have the variable by itself, we can divide by 2 on both sides to solve for x.

As we defined, x equals the amount of money that Isabella spent, which is $1302.52. We can plug that number into x + 438.47 to get the amount that Jesus spent, which we calculate to be $1740.99.

Thus, Isabella spent $1302.52 and Jesus spent $1740.99.

To check our work, we can simply add up the two amounts to see if it totals to $3043.51:

Answer:

Step-by-step explanation:

Yes, the lines are parallel.

so its d. trust me :)

The evaluation of the table, equations, and graphs in the question are as follows;

First question;

Part A; The table does not represent a function

Part B; The value of f(300) is $123 represents the total cost for driving 300 miles

Second question;

Part A; The equation is; y = -2·x + 8

Part B; The graph can be obtained by finding the ordered pair of values for the first five hours and plotting the result on a graph, to form a straight line graph.

Third question;

Part A; The solution is; (2, -1)

Part B; Two solutions for f(x) are; (1.5, 0) and (0, 3)

Part C; The solution for the equation, g(x) = f(x) is the point (0, 3)

A function is rule, law or expression that maps the elements of one set A unto the elements of another set B such that each element of the set A maps unto exactly one element of the set B.

First question;

Part A: The value of x = 4 has two values of y = 2, and -2

The value of x = 9 has to values of output, y = 3 and -3

The function therefore is; y = f(x) = ±√x

The above function indicates that a value of x returns two values of y, which indicates that a vertical line drawn through the graph of the function f(x) = ±√x intersects the graph twice for values of x > 0, therefore, the equation, f(x) = ±√x, represented by the values in the table is not a function

Part B: The function for the total cost of driving a car is f(x) = 90 + 0.11·x

Where; f(x) = The total cost in dollars

x = The distance the car is driven in miles

Therefore, f(300) is obtained by plugging in x = 300 as follows;

f(300) = 90 + 0.11 × 300 = 123

The value of f(300) = $123

f(300) represents the total cost of driving the car for 300 miles

Second question set;

The velocity of the runner after one hour = 6 km/h

The velocity of the runner after three hours = 2 km/h

Part A:  The ordered pair of points of the function are; (1, 6) and (3, 2)

Making use of a linear model, we get;

Slope of the equation of the model, m = (2 - 6)/(3 - 1) = -2

The equation of the model is therefore; y - 6 = (-2) × (x - 1) = -2·x + 2

y = -2·x + 2 + 6

y = -2·x + 8

Where: y = The speed of the runner

x = The number of hours the runner has been running

Part B:

The graph of the equation can be plotted from the values of y obtained from the corresponding values of x for the first 5 hours as follows;

[tex]\begin{array}{|c|c|}x & y \\1 & 6 \\2 & 4\\3 & 2 \\4 & 0 \\5 & -2\\\end{bmatrix}[/tex]

Please find attached the graph of the velocity of the runner with time created using the above table of values found with MS Excel

Third Question;

Part A; The solution to pair of equation can be found from the point of intersection of their graphs

Therefore, the solution of the pair of equations represented by p(x) and f(x) is the point of intersection of the graph of f(x) and p(x), which is the point (2, -1)

Part B; Two solutions for the function f(x) can be obtained by the point of intersection of the x- and y-axis as follows;

The x-intercept of f(x) = (1.5, 0)

The y-intercept of f(x) = (0, 3)

Part C; The solution for g(x) = f(x), is the point of intersection of g(x) and f(x), which is the point (0, 3)

As two angles are Complementary Angles they sum up to 90.

So value of d is 10.

Complementary angles are two angles whose total is 90 degrees in geometry. In other terms, complimentary angles are two angles whose sum is 90 degrees. 60° and 30°, for instance.

If two angles sum to 90 degrees, they are said to be complimentary angles. In other terms, a right angle is created when two complementary angles are combined (90 degrees). If the sum of angles 1 and 2 equals 90 degrees (i.e., angle 1 plus angle 2 = 90°), then the angles are complementary and are referred to as one another's complements.

60° + 30° in the figure below equals 90°. These two angles are therefore complimentary according to the "Definition of Complementary Angles." The term "complement" refers to each angle that is one of the complimentary angles. Here,

The opposite of 30° is 60°.

The opposite of 60° is 30°.

Given;

24,(7d-4) are complementary angles

So, 24°+7d-4 =90°;

⇒7d-4=90-24;

⇒7d-4=66;

⇒7d=70;

⇒d=10.

For isosceles trapezoid PQRS the coordinates for point R are;; (a - b, c).

We are told that the following figure is an isosceles trapezoid. This tells us that the two non - parallel sides of the given trapezoid are equal.

A parallel side of the trapezoid lies on the x-axis, which tells us that the opposite side is a horizontal line parallel to the x-axis and that the y-coordinate remains the same for all point lie on that side.

Since the opposite side has vertex (b, c), therefore the y-coordinate for point R is c.

The non-vertical sides are equal. Since the horizontal distance between (0,0) and (b, c) is b, then it means that the horizontal distance between point R and (a, 0) is b. So, the x-coordinate of R is (a - b).

Therefore we conclude that the coordinates for point R are (a - b, c).

A rigid transformation, also known as congruence transformation, in geometry, is one in which the length of the pre-image is preserved, such that the image and the pre-image have the same side lengths, and are therefore congruent.

The coordinates of the vertices of triangle ΔABC, obtained from a similar question online are;

A(-6, -1), B(-3, -3), C(-1, -2)

The lengths of the sides of triangle ΔABC are;

AB = √((-3 - (-6))² + (-3 - (-1))²) = √(13)

BC = √((-1 - (-3))² + (-2 - (-3))²) = √5

AC = √((-1 - (-6))² + (-2 - (-1))²) = √(26)

The law of cosines can be used to fined the measure of an angle of the triangle as follows;

Let a represent the side BC, let b represent the side AC, and let c represent the side AB, the formula for the law of cosines is presented as follows;

a² = b² + c² - 2·b·c·cos(A)

Where;

∠A = The angle at the vertex A

Therefore;

(√5)² = (√(26))² + (√(13))² - 2 × √(26) × √(13) × cos(A)

5 = 26 + 13 - 2 × √(26) × √(13) × cos(A)

cos(A) = (5 - (26 + 13))÷ (-2 × √(26) × √(13))

∠A = arccos((5 - (26 + 13))÷ (-2 × √(26) × √(13))) ≈ 22°

Similarly, we get:

cos(B) = (26 - (5 + 13))÷ (-2 × √(5) × √(13))

∠B = arccos((26 - (5 + 13))÷ (-2 × √(5) × √(13))) ≈ 120°

cos(C) = (13 - (26 + 5))÷ (-2 × √(5) × √(26))

∠C = arccos((13 - (26 + 5))÷ (-2 × √(5) × √(26))) ≈ 38°

The required probability is approximately 0.0228 that the diameter is greater than 85 millimeters.

The probability that the diameter of a selected bearing is greater than 85 millimeters can be found by calculating the z-score for 85 millimeters and then using the standard normal table to find the corresponding probability.

First, we need to standardize the value 85 millimeters by subtracting the mean diameter and dividing by the standard deviation:

z = (85 - 81) / (4 / sqrt(16)) = 4 / 2 = 2

Next, we can use the standard normal table to find the probability that a randomly selected bearing has a diameter greater than 85 millimeters.

Since the distribution is symmetric, we can find the probability that the diameter is less than 85 millimeters and then subtract this probability from 1 to find the probability that the diameter is greater than 85 millimeters. Looking up the z-score 2 in the standard normal table, we find that the probability that the diameter is less than 85 millimeters is approximately 0.9772.

Therefore, the probability that the diameter is greater than 85 millimeters is approximately 1 - 0.9772 = 0.0228.

[tex]\rm A = \ \$4,000 \times \left (1 + \dfrac{0.079}{4} \right)^{10\times 4}[/tex]

A = $4,000 × (1.01975)⁴⁰

A = $4,000 × 2.186

A = $8,745.98
