Answer:

2nd option is the correct answer.

\( 5\frac{1}{3}\: units\)

Step-by-step explanation:

\( In\:\triangle XWZ, \: \angle XWZ= 90°

\\ \: \&\: WY \perp XZ\\\)

Therefore, by geometric mean postulate:

\( WY^2 = XY\times YZ\\

\therefore 4^2 = 3\times a\\

\therefore 16 = 3a

\therefore a = \frac{16}{3}\\\\

\huge \red {\boxed {\therefore a = 5\frac{1}{3}\: units}} \)

The value of x is equal to 15°

In Mathematics and Geometry, the sum of the exterior angles of both a regular and irregular polygon is always equal to 360 degrees.

Note: The given geometric figure (regular polygon) represents a pentagon and it has 5 sides.

By substituting the given parameters, we have the following:

3x + 4x + 8 + 5x + 5 + 6x - 1 + 5x + 3 = 360°.

3x + 4x + 5x + 6x + 5x + 8 + 5 - 1 + 3 = 360°.

23x + 15 = 360°.

23x = 360 - 15

23x = 345

x = 345/23

x = 15°.

If I have the following exercise x = 8 + 9 * 4 + (32 * 2 + 5 * 4) + 3 * 6 applying the hierarchy of operations, the result would be?

a. 25

b. 45

c. 78

d. None of the above

Solution

The hierarchy of operations includes BODMAS.

B - Brackets

O - Order

D - Division

M - Multiplication

A - Addition

S - Subtraction

x = 8 + 9 * 4 + (32 * 2 + 5 * 4) + 3 * 6

Solving the bracket first.

The multiplication in the bracket are first simplified to give

x = 8 + 9 * 4 + (64 + 20) + 3 * 6

Then further simplifying the bracket

x = 8 + 9 * 4 + (84) + 3 * 6

We then solve the multiplication outside the brackets

x = 8 + 36 + 84 + 18

We now sum all of this

x = 146

In Spanish/En Español

La jerarquía de operaciones incluye BODMAS.

B - Soportes

O - Orden

D - División

M - Multiplicación

A - Suma

S - Resta

x = 8 + 9 * 4 + (32 * 2 + 5 * 4) + 3 * 6

Resolver el soporte primero.

La multiplicación en el paréntesis se simplifica primero para dar

x = 8 + 9 * 4 + (64 + 20) + 3 * 6

Luego simplificando aún más el soporte

x = 8 + 9 * 4 + (84) + 3 * 6

Luego resolvemos la multiplicación fuera de los corchetes

x = 8 + 36 + 84 + 18

Ahora sumamos todo esto

x = 146

The slope of the line that passes through the points (-3, 3), and (1, -5) is -2.

Steps to finding slope:

The formula for finding slope from two points (x₁, y₁) and (x₂, y₂) on a line is m = (y₂ - y₁) / (x₂ - x₁). Here,

m = slope of the line

x₁ = the x-coordinate of the first point

y₁ = the y-coordinate of the first point

x₂ = the x-coordinate of the second point

y₂ = the x-coordinate of the second point

Here, the given points are  (-3, 3), and (1, -5):

y₂ = -5, y₁ =3 , x₂ = 1, x₁ = -3

Substitute the values,

m = (y₂ - y₁) / (x₂ - x₁)

m = (-5 - 3) / (1 - (-3))

= -8 / (1+3)

= -8 / 4

m = -2

Hence, the slope of the line that passes through the points (-3, 3), and (1, -5) is -2.

The function which represents f as required to be determined in the task content is; f (t) = 41t + t³ / 3 + 41 ⅓.

According to the task content; it is required that the function f be determined from the given information.

Since the function f which is to be determined has its differential provided as in the task content;

f '(t) = 41 + t²

Since the function f is differentiable; it follows that f' (t) can be integrated as an indefinite integral so that we have;

f (t) = 41t + t³/3 + c

where c is the constant of integration.

Therefore;

f (1) = 41 (1) + (1)³/3 + c = 0

Therefore; c = 41 ⅓

On this note, the function f (t) can be written as;

f (t) = 41t + t³ / 3 + 41 ⅓.

We know that 1 gallon = 3.785 L,Therefore, 24.1364 L = 24.1364/3.785 gallons= 6.3781 gallons (rounded to four decimal places)Therefore, the car will use approximately 6.3781 gallons of gas on this trip.

The car travels for 3.0 hours at a velocity of 55 miles per hour. The gas mileage of the car is 11 km/L. We have to find how many gallons of gas will be used on this trip. We can solve this problem by using the following steps:Step 1: Convert the velocity from miles per hour to km/hourWe know that 1 mile

= 1.609 km Therefore, 55 miles per hour

= 55 × 1.609 km per hour

= 88.5 km per hour Step 2: Calculate the distance traveled by the car We know that distance = velocity × time Therefore, distance traveled by the car

= 88.5 km/hour × 3.0 hours

= 265.5 km

Step 3: Convert the distance from kilometers to miles We know that 1 mile

= 1.609 km Therefore, 265.5 km

= 265.5/1.609 miles

= 165.1287 miles (rounded to four decimal places)Step 4: Calculate the fuel consumption in liters We know that fuel consumption

= distance traveled/gas mileage Therefore, fuel consumption

= 265.5 km/11 km/L

= 24.1364 L (rounded to four decimal places)Step 5: Convert the fuel consumption from liters to gallons.We know that 1 gallon

= 3.785 L,Therefore, 24.1364 L

= 24.1364/3.785 gallon

s= 6.3781 gallons (rounded to four decimal places)Therefore, the car will use approximately 6.3781 gallons of gas on this trip.

The lengths of each line segment are listed below:

In this problem we find three line segments, of which the coordinates of all ends are known, and we must determine the lengths of each segment, task to be done by applying Pythagorean theorem.

If we know that A(x, y) = (0, 2), B(x, y) = (5, 4), C(x, y) = (- 6, 0), D(x, y) = (- 7, 5), E(x, y) = (- 5, - 8), F(x, y) = (- 6, - 2), then the length of each segment is:

AB = √[(5 - 0)² + (4 - 2)²]

AB = √(5² + 2²)

AB = √(25 + 4)

AB = √29

AB ≈ 5.385

CD = √[[- 7 - (- 6)]² + (5 - 0)²]

CD = √[(- 1)² + 5²]

CD = √(1 + 25)

CD = √26

CD ≈ 5.099

EF = √[[- 6 - (- 5)]² + [- 2 - (- 8)]²]

The requried another dose of Robitussin would need to be taken at least 5 hours after the initial dose in order for the body to maintain the minimum effective amount of 100 mg.

Let t be the number of hours that have passed since the dose was taken, and let A(t) be the amount of Robitussin in the body at time t. We know that A(0) = 1000 mg (the initial dose), and that A(t) = 0.55 A(t-1) (the rate of decay is 55% per hour).

We want to find the value of t such that A(t) = 100 mg. We can use recursive substitution to find A(t) in terms of A(0):

A(1) = 0.55 A(0) = 0.55 * 1000 = 550

A(2) = 0.55 A(1) = 0.55 * 550 = 302.5

A(3) = 0.55 A(2) = 0.55 * 302.5 = 166.375

A(4) = 0.55 A(3) = 0.55 * 166.375 = 91.50625

A(5) = 0.55 A(4) = 0.55 * 91.50625 = 50.3284375

So, after 5 hours, the amount of Robitussin in the body drops below 100 mg.

Graf 2 is correct

Step-by-step explanation:

The correct graph that represents the linear relationship is Graph B with a positive slope.

The table shows a linear relationship between the number of months enrolled and the total cost paid for the membership.

To determine which graph represents this relationship, we need to check if the cost increases or decreases as the number of months enrolled increases. If the cost increases, it means the graph should have a positive slope. If the cost decreases, it means the graph should have a negative slope.

Let's look at the table:

Number of Months Enrolled                                   Total Cost

1                                                                               75

2                                                                               100

3                                                                                 125

As the number of months enrolled increases, the total cost increases. Therefore, the graph should have a positive slope. From the given options, the graph that correctly represents this linear relationship is Graph B, which has a positive slope.

13/sqrt2 or 13sqrt2/2

Step-by-step explanation:

Since there is no other information, the two other angles (not the 90 degree one) are equal to each other which makes it a 45-45-90 triangle.

A 45-45-90 triangle is x-x-xsqrt2

so x and y equals = 13/sqrt2

The measure of side EF in triangle DEF is 5.34 units when angle D measures 40° and its adjacent side measures 7.6 units.

To get this answer, use the Pythagorean Theorem:

a2 + b2 = c2,

where a and b are the lengths of the sides adjacent to the right angle, and c is the length of the hypotenuse.

In this case, a = 7.6 and b = 5.34, so c = 8.93. Round this to the nearest hundredth and you get 5.34.

The Pythagorean Theorem states that in a right triangle, the sum of the squares of the two sides adjacent to the right angle is equal to the square of the hypotenuse.
