The average speed of the body in the given interval is 32 + 2z ft/s.

The average speed v of a body in an interval of z seconds can be calculated using the formula v = d/t, where d is the distance traveled and t is the time taken.

In this case, the distance d is (32z + 2z^ 2 ) ft and the time taken is z seconds.

Therefore, the average speed v of the body in this interval is:

v = (32z + 2z^ 2 ) ft / zs

v = 32 + 2z ft/s

Therefore, the average speed of the body in the given interval is 32 + 2z ft/s.

Solving an equation we will see that Caitlyn used 3 of the 42-cent stamps and 9 of the 5-cent ones.

Let's define the variables that we will be using:

Then the total value of the stamps, in dollars, is:

x*0.42 + y*0.5

And we know that the value must be $1.71, then we can write the equation:

x*0.42 + y*0.05 = 1.71

y = (1.71 - x*0.42)/0.05

To find the values of x and y, we can just evaluate in different whole values of x, until we get a whole value of y.

using x = 1 we get:

y = (1.71 - 0.42)/0.05 = 2.58

This is not a solution.

if x = 3

y = (1.71 - 0.42*3)/0.05 = 9

This is the solution, she used 3 of the 42-cent and 9 of the 5-cent.

Answer:

10th term = 94

Step-by-step explanation:

Given equation,

→ Tn = n² - n + 4

Now the 10th term will be,

→ Tn = n² - n + 4

→ T10 = (10)² - 10 + 4

→ T10 = 100 - 6

→ [ T10 = 94 ]

Hence, the answer is 94.

The area the polygon in the diagram with, a length from the center to the vertex 6√2 in is 144.0 in².

Any closed curve that consists entirely of connected line segments (sides) without any intersections is known as a polygon in geometry. The three simplest polygons are pentagons, triangles with three sides, and quadrilaterals with four sides (five sides). The two types are concave and convex polygons.

Convex polygons are those without any extended sides crossing over them. Equilateral refers to a polygon with equal sides. Interior angles of equiangular shapes are equal. Every equilateral and equiangular polygon is a regular polygon (e.g., an equilateral triangle or a square).

As all sides are equal, all diagonals are equal too, and the angle of adjacent diagonals are 90° with vertical opposite angle.

Therefore,

Each side = [tex]\sqrt{\text {diagonal}^2+ \text {diagonal}^2}[/tex]

Each side = [tex]\sqrt{(6\sqrt{2} )^2+(6\sqrt{2} )^2}[/tex]

Each side = [tex]\sqrt{(36\times 2+36\times 2}[/tex]

Each side = [tex]\sqrt{144}[/tex]

Each side = 12 inch

Area =  12 × 12

         = 144.0 in²

Thus, the area the polygon in the diagram with, a length from the center to the vertex 6√2 in is 144.0 in².

The sums of the measures of the interior angles of a polygon is three times the sum of its exterior angles then it has 8 sides .

What is Polygon?

A polygon is a two-dimensional, closed form that is flat or planar and is limited by straight sides. Its sides are not curled. A polygon's edges are another name for its sides. The vertices (or corners) of a polygon are the places where two sides converge. Here are some illustrations of polygons.

What is interior angles?

Interior angles are those that are located within the confines of two parallel lines that are intersected by a transversal.

What is exterior angles?

The angles that are created outside of a triangle are its external angles. In other terms, the angle created between one of a triangle's sides and its neighboring extended side is the triangle's external angle.

We know that sum of interior angle of regular polygon is ;

(n-2) x 180°

Where n = no. of sides

We also know that sum of exterior angle of regular polygon is 360°.

The fact that the sum of a polygon's internal angles is three times the sum of its outside angles is now a given;

Therefore;

sum of interior angles of a regular polygon = 3 x sum of exterior angle

⇒ (n-2) x 180°

⇒3 x 360°

Simplify the equation we have above by:

⇒(n-2) = 3 x 360°/180° = 6

⇒ n = 6+2 = 8

The probability that the total weight of the passengers on a full flight exceeds 6000 pounds is about 0.0147 or 1.47%.

What is the Central Limit Theorem?

The Central Limit Theorem states that the sum of a large number of independent and identically distributed random variables is approximately Normally distributed.

(a) The reason why you cannot calculate the probability that a randomly selected passenger weighs more than 200 pounds is that the weight of passengers is not Normally distributed.

The Normal distribution is a symmetric bell-shaped distribution that is defined by its mean and standard deviation.

The weight of passengers is not symmetric and it may not follow a bell shape.

Therefore, we cannot use the Normal distribution to calculate the probability of a weight greater than 200 pounds.

(b) To calculate the probability that the total weight of the passengers on a full flight exceeds 6000 pounds, we can use the Central Limit Theorem.

Since we don't know the exact distribution of the weight of the passengers, we can use the Central Limit Theorem to approximate the total weight of the passengers on a full flight.

The mean weight of a passenger is 190 pounds, and the standard deviation is 35 pounds. Since a full flight carries 30 passengers, the mean weight of the passengers on a full flight is 19030 = 5700 pounds and the standard deviation is 35sqrt(30) = 175 pounds.

To find the probability that the total weight of the passengers on a full flight exceeds 6000 pounds, we can use the standard normal distribution table.

z = (6000 - 5700) / 175 = 2.2857

Probability P(X > 6000) = P(Z > 2.2857) = 1 - P(Z < 2.2857) = 1 - 0.9853 = 0.0147

Hence, the probability that the total weight of the passengers on a full flight exceeds 6000 pounds is about 0.0147 or 1.47%.

The distance traveled during the given time interval be 2024 m.

An object's rate of change in velocity is referred to as its acceleration. The rate of change in velocity is known as acceleration. Acceleration typically signals a change in speed, though this is not always the case. Because of the shifting direction of its velocity, an item moving on a circular path at a constant speed is still accelerating.

By integrating the velocity v in terms of time t, v = gt, we can determine acceleration, which is the rate of change of velocity with respect to time.

Let the function be a(t) = t + 4

time = 11

substitute the value of t in the above equation, we get

a(11) = 11 + 6 = 17 m/s²

a = v/t, so v = at

finally v = (17 m/s²) (11s)

v = 187 m/s

b) Find the distance traveled during the given time interval

[tex]$$V_{total} = V_{final} - V_{ initial[/tex]

V final = 187 m/s, Vinitial = 3 m/s

V total = 187 - 3 = 184 m/s

Let the equation of velocity be

Velocity = distance/time

distance = velocity × time

distance = 184 m/s × 11 s

distance = 2024 m
