The stock was worth $85. What will the stock be worth in 7 years? WhThe value of πPhone stock has increased 8% each year for the past several years. In 2020,at was the stock worth in 2016? Equation: 7 years from now? In 2016?

Answers

Answer 1

Answer:

Part A

The worth of the stock in 7 years is approximately $145.68

Part B

The worth of the stock in 2016 is approximately $62.48

Part C

f(7) = 85 × (1 + 0.08)⁷

Part D

85 × (1 + 0.08)⁻⁴

Step-by-step explanation:

Question

"The value of the πPhone πhas increased 8% each year for the past several years. In 2020, the stock was worth $85. What will the stock be worth in 7 years? What was the stock worth in 2016? Equation: 7 years from now? in 2016?"

The equation for the growth of the stock to a final amount f(x) is given by the general equation for exponential growth as follows;

[tex]f(t) = a \cdot (1 + r)^t[/tex]

Where, in relation to the stocks;

f(t) = The value of the stocks after 't' years

a = The initial amount of the stocks

r = The rate of growth of the stock = 8%

t = The number of years of growth

Part A

The worth of the stock in 7 years, f(7), is found as follows;

The (initial) value of the stock in 2020, a = $85

The rate of increase in the value of the stock = The growth rate of the stock, r = 8% = 8/100 = 0.08

The number of years of growth, t = 7 years

We get;

f(7) = 85 × (1 + 0.08)⁷ ≈ 145.68

The worth of the stock in 7 years, f(7) ≈ $145.68

Part B

The value of the stock in 2016 is found as follows;

The number of years between 2020 and 2016 = 2016 - 2020 = -4 (years)

Here, let 'f(t)' represent the value of the stock in 2016, and therefore, we have;

t = -4 years

r = 8% = 0.08

a = The value of the stock in 2020 = $85

Plugging in the values gives;

f(-4) = 85·(1 + 0.08)⁻⁴ = 85 × (1.08)⁻⁴ ≈ 62.48

The value of the stock in 2016, f(-4) ≈ $62.48.

Part C

The equation for 7 years from now is f(7) = 85 × (1 + 0.08)⁷

Part D

The equation for 2016 is f(-4) = 85 × (1 + 0.08)⁻⁴.

Find the volume and surface area of the composite figure shown below if the figure is built with unit cubes.

Answers

Answer:

the volume is 18 and the surface area is 46

Step-by-step explanation:

The volume of the cube will be and the surface area of the cube will be square units.

What is volume?

Volume is defined as the space covered by any solid body in the three-dimensional plane. The volume of the cube will be calculated by multiplying all three sides of the cube.

The volume will be calculated as below:-

The formula to calculate the volume = l x w x h

The volume of the first part = 2 x 2 x 3 = 12 cubic units

The volume of the Second part = 2 x 2 x 1 = 4 cubic units

The volume of the third part  = 2 x 1 x 1 = 2

Total volume of the cube  = 12 + 4 + 2 = 18 cubic units.

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.

The surface area will be calculated as below:-

Surface area of the base = 2 ( 4 x 2) + 2( 2x 1) + 2 ( 4x 1) = 28

Surface area of the middle = 2 ( 3 x 2 ) + 2 ( 2 x 1 ) + 2 ( 3 x 1) = 22

Surface area of the upper side = 2 ( 2 x 2) +2 ( 1 x 2 ) + 2 ( 1 x 2) = 16

The total surface area is calculated as below:-

Total = 28 + 22 + 16 = 66 square units.

The mean absolute deviation is 46,54,43,57,50,62,78,42

Answers

8.75 hope this helps

The mean absolute deviation (MAD) of the given set of numbers is 8.75.

What is the mean absolute deviation (MAD)?

The mean absolute deviation (MAD) of a group of data points is a statistical metric used to evaluate its dispersion or variability. It indicates how far off the data values are from the mean (average) of the data collection.

Let's calculate the MAD for the given set of numbers: 46, 54, 43, 57, 50, 62, 78, 42.

Calculate the mean:

Mean = (46 + 54 + 43 + 57 + 50 + 62 + 78 + 42) / 8 = 432 / 8 = 54

Find the absolute difference between each number and the mean:

|46 - 54| = 8

|54 - 54| = 0

|43 - 54| = 11

|57 - 54| = 3

|50 - 54| = 4

|62 - 54| = 8

|78 - 54| = 24

|42 - 54| = 12

Calculate the average of these absolute differences:

MAD = (8 + 0 + 11 + 3 + 4 + 8 + 24 + 12) / 8 = 70 / 8 = 8.75

Therefore, the mean absolute deviation (MAD) of the given set of numbers is 8.75.

Step-by-step explanation:

d because there are no numbers common to  both sets

Disjoint sets are those sets that have no common values between the sets.

A: numbers above 100; B: numbers less than -200​ is a disjoint set.

Option D is the correct answer.

What is a set?

A set is a collection of items where there are operations such as:

Union of sets, the intersection of sets, complements of sets.

We have,

Disjoint sets are those sets that have no common values between the sets.

a) A: odd numbers; B: the number 5

Set A = {1, 3, 5, 7, 9,.....}

Set B = {5}

A ∩ B = {5}

This is not a disjoint set.

b) A: even numbers; B: numbers greater than 10

A =  {2, 4, 6, 8, 10, , , }

B = {11, 12, 13, 14, 15, 16, 18,,,,,}

A ∩ B = {12, 14, 16, 18,,,}

This is not a disjoint set.

c) A: numbers less than 5; B: all negative numbers

A = {, , ,, -3, -2, -1, 0, 1, 2, 3, 4}

B = {, , , , -3, -2, -1}

A ∩ B = { , , , , -3, -2, -1}

This is not a disjoint set.

d) A: numbers above 100; B: numbers less than -200​

A = {101, 102, 103, 104, ,,,,,,}

B = {, , , , -204, -203, -202, -201}

A ∩ B = Ф

There are no common values between set A and set B.

This is a disjoint set.

Thus,

A: numbers above 100; B: numbers less than -200​ is a disjoint set.

A skateboarder goes off of a ramp at a speed of 52 ft./s. The ramp is 5 ft. above the ground with a 30°

angle of elevation. Which set of parametric equations represents the skater's jump? The acceleration due

to gravity is 32 ft/s^2.

Answers

The set of parametric equations representing the skater's jump is:

x = 52t

y = 5 + 16t²

We have,

Let's denote the time as t.

Horizontal motion:

The skateboarder's horizontal velocity remains constant throughout the jump, so the horizontal position (x) can be represented as:

x = vt

where v is the horizontal velocity, which in this case is 52 ft/s.

Vertical motion:

The vertical position (y) can be determined using the equations of motion under constant acceleration.

The skateboarder experiences acceleration due to gravity (g) acting downward.

The initial vertical position is 5 ft, and the initial vertical velocity is

0 ft/s.

Using the equation of motion:

[tex]y = y_0 + vy_0t + 0.5gt^2[/tex]

Substituting the given values:

y = 5 + 0t + 0.5(32)t²

y = 5 + 16t²

Thus,

The set of parametric equations representing the skater's jump is:

x = 52t

y = 5 + 16t²

A car travels for 2 hours 15

Answers

Answer:

231.746 km

Step-by-step explanation:

Formula: [tex]distance = speed[/tex] × [tex]time[/tex]

Solution: To solve for distance use the formula for distance

Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.

Firstly, convert the time from hours to minutes

2 hr 15 min = 2.25 hr

or 2.25 hr = 135 min

Now, use the formula:

135 × 64 = 8640
