Answer :

(i) The size of angle x is 58⁰.

(ii) The size of angle y is 70⁰.

Step-by-step explanation :

From the given figure we conclude that:

∠EFB = ∠FGD = x⁰   (corresponding angles are equal)

∠FGD = ∠CGH         (vertically opposite angles are equal)

x⁰ = 58⁰

∠FGD = ∠AFG = 58⁰ (alternate angles are equal)

Now we have to calculate the value of 'y'.

As we know that the sum of interior angle of a triangle is equal to 180⁰.

In ΔAGF,

∠GAF + ∠AFG + ∠FGA = 180⁰

52⁰ + 58⁰ + y = 180⁰

110⁰ + y = 180⁰

y = 180⁰ - 110⁰

y = 70⁰

Therefore, the value of size of angle x and angle y is 58⁰ and 70⁰ respectively.

To create a relative frequency distribution, we need to count the number of occurrences of each response and divide it by the total number of responses, which is 20 in this case. The relative frequency of classmates who say their favorite month is June can be calculated as follows:

Number of classmates who say their favorite month is June: 2

Relative frequency of classmates who say their favorite month is June: 2/20 = 1/10 = 0.1

So, the relative frequency of his classmates who say their favorite month is June is 0.1 or 10%.

Relative frequency is a measure of the proportion or percentage of observations in a dataset that belong to a specific category or interval. It is calculated as the count of observations in a specific category or interval divided by the total number of observations in the dataset.

Definite integral ∫(0 to √6) f(x) dx using Simpson's rule is less than 0.00001, we need to calculate the error formula for Simpson's rule and iterate over different values of n until the error estimate satisfies the given condition.

Simpson's rule is a numerical method used for approximating definite integrals. The error estimate for Simpson's rule is given by the formula:

\(E = -((b - a)^5 / (180 * n^4)) * f''(c)\)

Where E represents the error estimate, (b - a) is the interval length (in this case, √6 - 0 = √6), n is the number of subintervals, f''(c) is the second derivative of the function evaluated at a point c within the interval.

To find the smallest n for which the error estimate is less than 0.00001, we can start by choosing an arbitrary value of n, calculating the error estimate using the given formula, and then checking if it is smaller than the desired tolerance. If it is not, we increase the value of n and recalculate the error estimate until it meets the condition.

By iteratively increasing the value of n and calculating the error estimate, we can determine the smallest value of n for which the error estimate in the approximation of the definite integral satisfies the condition of being less than 0.00001.

The depth at which the scuba diver will experience a pressure of 40.5 psi can be found by using the proportional relationship between water pressure and depth. Based on the given information, the depth can be calculated to be 90 feet below the surface.

The scuba diver's depth and the water pressure are directly proportional to each other. If the pressure on the diver is 31.5 psi at a depth of 70 feet, we can use this information to find the depth at which the pressure will be 40.5 psi.

Let x be the depth at which the pressure is 40.5 psi. Using the proportionality, we can write:

31.5/70 = 40.5/x

We can solve for x by cross-multiplying:

31.5x = 2835

x = 90

Therefore, the diver will be 90 feet below the surface when the pressure is 40.5 psi.

The pattern of the data indicates a linear relationship or strong positive correlation between the average house prices and average monthly payments.

The monthly payment for a house costing $450,000 is $3,600.

A formulate connecting the average monthly payment with the average house price in slope-intercept form is y = 0.008x.

In Mathematics, a proportional relationship can be represented by this equation:

y = kx

Where:

Next, we would determine the constant of proportionality (k) as follows:

Constant of proportionality (k) = y/x

Constant of proportionality (k) = 8/1000

Constant of proportionality (k) = 1/125 or 0.008.

Therefore, a formula that connects the two variables is given by;

y = kx

y = 0.008x

When average house price (x) = $450,000, the average monthly payment (y) is given by:

y = 0.008(450,000)

y = $3,600.

In conclusion, we can logically deduce that the pattern of the data shows a linear relationship or strong positive correlation between the average house prices (x) and average monthly payments (y) because as the average house prices (x) increases, the average monthly payments (y) also increases.

The required probability that sam has to get change for the 10-dollar bill before he can buy his favorite toy is 6/7.

The fraction of favorable outcomes to the total number of outcomes of an event is said to be its probability of occurrence.

P(N) = n(N)/n(S)

N- an event; S- total outcomes;

It is given that,

n(s) = 8

So, the probability of buying the favorite toy first is 1/8

and the probability of buying the favorite toy a second is (1/8)(1/7) = 1/56

For these probabilities, Sam won't need to change the 10-dollar bill.

Then,

The probability that Sam has to get change for the 10-dollar bill before he can buy his favorite toy is

The initial-value problem y' = 2x, y(0) = 1 has a unique solution, which is \(y = x^2 + 1\). Theorem 5.4 can be applied in this case as the function and its partial derivative are continuous on the given interval.

To show that each of the following initial-value problems has a unique solution and find the solution, we need to check if Theorem 5.4 can be applied in each case.

a. For the initial-value problem y' = 2x, y(0) = 1:
Theorem 5.4 states that if the function f(x, y) and its partial derivative ∂f/∂y are continuous on a rectangle R, then the initial-value problem has a unique solution on an interval containing the initial point.

In this case, f(x, y) = 2x and ∂f/∂y = 0. Both f(x, y) and ∂f/∂y are continuous everywhere. So, Theorem 5.4 can be applied and the initial-value problem has a unique solution.

To find the solution, we can integrate both sides of the equation y' = 2x with respect to x:
∫ dy = ∫ 2x dx
\(y = x^2 + C\)

Using the initial condition y(0) = 1, we can substitute x = 0 and y = 1 into the solution equation:
\(1 = 0^2 + C\)
C = 1

So, the solution to the initial-value problem y' = 2x, y(0) = 1 is \(y = x^2 + 1\).

The initial-value problem y' = 2x, y(0) = 1 has a unique solution, which is \(y = x^2 + 1\). Theorem 5.4 can be applied in this case as the function and its partial derivative are continuous on the given interval.

Answer:

75°, 85°, 95°, 105°

Step-by-step explanation:

Since the 4 angles form an AP, then the 4 angles are

a, a + d, a + 2d, a + 3d

where a is the first term and d the common difference

The sum of the angles in a quadrilateral = 360° thus

a + a + d + a + 2d + a + 3d = 360, that is

4a + 6d = 360, substitute d = 10

4a + 60 = 360 ( subtract 60 from both sides )

4a = 300 ( divide both sides by 4 )

a = 75

Thus the 4 angles are

75°, 75° + 10° = 85°, 75° + 20 = 95°, 75° + 30° = 105°

Answer:

To solve this problem, we can use the following formula:

Volume of a pyramid = (1/3) * base area * height

The first step is to calculate the height of the pyramid. Since each side wall makes an angle of 45° with the plane of the base, the height is equal to the length of the altitude of the rhombus. The altitude can be calculated using the Pythagorean theorem:

altitude = sqrt((diagonal/2)^2 - (side/2)^2)

= sqrt((5.4/2)^2 - (4.5/2)^2)

= 2.7 cm

The base area of the pyramid is equal to the area of the rhombus:

base area = (diagonal1 * diagonal2) / 2

= (4.5 * 4.5) / 2

= 10.125 cm^2

Now, we can calculate the volume of the pyramid:

Volume = (1/3) * base area * height

= (1/3) * 10.125 * 2.7

= 9.1125 cm^3

Therefore, the volume of the pyramid is 9.1125 cm^3.

To calculate the area of the pyramid, we need to find the area of each triangular face. Since the pyramid has four triangular faces, we can calculate the total area by multiplying the area of one face by 4. The area of one face can be calculated using the following formula:

area of a triangle = (1/2) * base * height

where base is equal to the length of one side of the rhombus, and height is equal to the height of the pyramid. Since the rhombus is a regular rhombus, all sides have the same length, which is equal to 4.5 cm. Thus, we have:

area of a triangle = (1/2) * 4.5 * 2.7

= 6.075 cm^2

Therefore, the total area of the pyramid is:

area = 4 * area of a triangle

= 4 * 6.075

= 24.3 cm^2

Hence, the area of the pyramid is 24.3 cm^2.

Answer:-10

Step-by-step explanation:

Formula for mid point is :

Mid point = ( (x1+x2)÷2 , (y1+y2)÷2) )

So, X1 = 4

X2 = X

Y1 = -2

Y2 = y

Now, use the formula

(-3,1) = ( (4 + x)÷2 , (-2+y)÷2) )

Now divide the sides for yourself to solve for midpoint for X and y separately

-3 = (4+x) ÷ 2 and 1 = (-2+y) ÷ 2

This is because 3 is the x coordinate of the mid point of A and B , so we equate it to (4+x) ÷ 2 because this expression basically gives us the x coordinate of mid point of A and B. So we already have the x coordinate of midpoint which is -3 so we can use this to find X coordinate of point B

So then we solve it by multiplying the 2 with -3 which gives -6

-6 = 4+X

Shift 4 on the other side and it will become negative 4

-6-4 = X

X = -10

Answer:

B (-10,4)

Step-by-step explanation:

Given A (4,-2) and midpoint M (-3,1) we can find equation of the line

y = mx +b

slope m = raise / run

m = (y1 - y2) / (x1 - x2)

m = (-2 - 1) / (4 - -3)

m = -3 / 7 = -3/7

given the midpoint M, then point B (x,y) must have the same length and slope as AM. So point B must have twice the rise and twice the run.

Slope was -3/7 so segment AB must be 2(slope) = -6/14, so from point A, point B will be from A (4,-2)

raise = y1 - y2 = -6

-2 - y2 = -6

-y2 = -6 + 2

y2 = 4

run = x1 - x2 = 14 = 4 - x2

14 - 4 = -x2

x2 = -10

If 624 minutes are used, the total cost will be dollars is $2,493.92.

Part A :

With the information given in the problem, we know that (i) "if a customer uses 150 minutes, the monthly cost will be $83" and (ii) "if the customer uses 980 minutes, the monthly cost will be $332."

From the information given in (i), we can set up the equation where y = total monthly payment = 83, x = minutes = 150, and where b = monthly fee which is an unknown value.

This gives the equation : y = mx+b --> 83 = 150m + b

*Note: m = the slope = rate, which can be defined as the $/min.

From the information given in (ii), we can set up the equation where y = total monthly payment = 332, x = minutes = 980, and where b = monthly fee which is an unknown value.

This gives the equation: y = mx + b --> 332 = 980m + b

At this point, we have two equations with two unknown values, m and b which are constant in both equations. The values that were given are the (x,y) values. To find the unknown m and b values, we can first use an equation to isolate one of the variables.

Solving for m:

From the first equation, b = 83 - 150m.

We can substitute this value of b into the second equation: 332 = 980m + (83 - 150m)

Solve for m:

332 - 83 = 980m - 150m

249 = 830m

m = 3.33

Solving for b:

From the first equation, since solving for m, we know that 83 = 150(3.33) + b

Now, we know that b = 83 - (150)3.33 = 416.50

Answer for Part A: y = 3.33 x + 416

Part B:

Using the equation y = 3.33 x + 416, we can substitute 624 minutes for x.

y = 3.33 (624) + 416

y = 2493.92

Answer for Part B: If 624 minutes are used, the total cost will be $2,493.92.
