You deposit $320 in an account that earns simple interest at an annual rate of 7.5% IS there enough money in the account after 3 years to buy a game console that costs $400?

Answers

Answer:

no

Step-by-step explanation:

simple interest formula:

final amount = initial balance * (1 + interest rate * time)

rate = 7.5% = 0.075

initial balance = 320

time = 3

is the final amount of 320 * (1 + 0.075 * 3) greater than or equal to 400?

320 * (1 + 0.075 * 3) = 392 so no

Based on the diagram below, which is closest to the height of the tree?

answer options and picture are below

Answers

Using the concept of similar triangles, the height of the tree is; Option D: 38 ft 6 inches.

How to find the side lengths of similar triangles?

Similar triangles are defined as triangles that have the same shape, but then their sizes may vary. This means that equilateral triangles and squares are good examples of similar objects. Thus, if two triangles are similar, then it means that their corresponding angles are congruent and corresponding sides are in equal proportion.

Thus, applying the principle of similar triangles above to the given image, if the height of the tree is h, then we have;

5/3.25 = h/25

h = (25 * 5)/3.25

h = 38.462 ft = 38 ft + 0.462 ft

Now, conversion of ft to inches gives 0.462 ft approximately 6 inches Thus, our final answer is 38 ft 6 inches.

Omar is going to invest in an account paying an interest rate of 6% compounded monthly. How much would Omar need to invest, to the nearest dollar, for the value of the account to reach $32,400 in 20 years?

Answers

Omar needs to invest $9,788, to the nearest dollar, for the value of the account to reach $32,400 in 20 years

What is compound interest rate?

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

x = P (1+r/n[tex])^{nt}[/tex]

,where x = compound interest

P = principal (the initial deposit or loan amount)

r = annual interest rate

n = the number of compounding periods per unit of time

t = the number of time units the money is invested or borrowed for

Given:

Omar is going to invest in an account paying an interest rate of 6% compounded monthly.

A =  $32,400 in 20 years

First, convert R as a percent to r as a decimal

r = R/100

r = 6/100

r = 0.06 per year,

Then, solve the equation for P

P = A / (1 + r/n[tex])^{nt}[/tex]

P = 32,400.00 / (1 + 0.06/12[tex])^{(12)(20)}[/tex]

P = 32,400.00 / (1 + 0.005[tex])^{240}[/tex]

P = $9,787.91

P = $9788  to the nearest dollar.

Therefore, the investing amount is $9,788.

If you roll 2 dice, what is the probability that you will roll a seven (the numbers on the dice add up to a seven) on or before the 5th roll

Answers

Answer:

The probability of rolling a seven on or before the 5th roll is 5/6 or about 83.3%

Step-by-step explanation:

The probability of rolling a seven on any given roll of two dice is 1/6, since there are six ways to roll a seven (1+6, 2+5, 3+4, 4+3, 5+2, 6+1) out of the 36 possible outcomes (1-6 on the first die and 1-6 on the second die).

To find the probability of rolling a seven on or before the 5th roll, we can use the cumulative probability formula which is the probability of getting a specific event on the first roll plus the probability of getting the event on the second roll plus the probability of getting the event on the third roll and so on.

So the probability of rolling a seven on or before the 5th roll is:

P(rolling a seven on the 1st roll) + P(rolling a seven on the 2nd roll) + P(rolling a seven on the 3rd roll) + P(rolling a seven on the 4th roll) + P(rolling a seven on the 5th roll)

= (1/6) + (1/6) + (1/6) + (1/6) + (1/6)

= 5/6

So the probability of rolling a seven on or before the 5th roll is 5/6 or about 83.3%

It's worth noting that this probability is independent of the previous outcomes of the rolls, so the probability of rolling a seven on or before the 5th roll stays the same even if you already rolled a seven in previous rolls.

The circle with a 7 feet radius cut into 6 equal sectors, indicates, using 22/7 approximation for pi, that the area of 2 of the pieces is 51 and one third square feet. The correct option is option C.

C. 51 and one third square feet

What is a sector of a circle?

A sector of a circle is a pie shaped part of a circle that is bounded by an arc and two radii of the circle.

The specified radius of the circle, r = 7 feet

The number of pieces to which the circle is cut into = 6 equal pieces (sectors)

The area of 2 of the pieces, using 22/7 as an approximation for π are found as follows;

Area of a circle, A = π × The square of the radius

Therefore; A = π × r²

A = (22/7) × 7² = 154

The area of the circle is about A = 154 square feet

The area of one of the pieces into which the circle is cut is therefore;

Area of a piece = A/6

Area of one piece = (154 square feet)/6 = 25 and two thirds square feet

The area of 2 of the pieces = 2 × (A/6) = A/3

Therefore, the area of two of the pieces = (154 square feet)/3 = 51 1/3

The area of 2 of the pieces = [tex]51\frac{1}{3}[/tex] square feet

Find an explicit formula for the geometric sequence -3, -12, -48, -192, -768

Answers

Answer:

a4 = -3 * 4^(4-1) = -3 * 4^3 = -3*64 = -192

Step-by-step explanation:

A geometric sequence is a sequence of numbers such that the ratio of any two consecutive terms is always the same. In this case, the given sequence is -3, -12, -48, -192, -768.

To find the explicit formula for this geometric sequence, we can use the following formula:

an = a1 * r^(n-1)

where:

a1 is the first term in the sequence (-3)

an is the nth term in the sequence

r is the common ratio (the ratio between any two consecutive terms)

To find the common ratio, we can divide -12 by -3, -48 by -12, -192 by -48, and -768 by -192, and in all cases we get r = 4

Therefore, the explicit formula for this geometric sequence is:

an = -3 * 4^(n-1)

This formula can generate any term of the sequence given the value of n.

So, for example, the fourth term of the sequence, -192, can be obtained by inputting n = 4 in the explicit formula:

a4 = -3 * 4^(4-1) = -3 * 4^3 = -3*64 = -192

Answers

The volume of a cone is given by the formula V = (1/3) * π * r^2 * h Where the volume of this cone is approximately A:2016.

What is volume of cone?

The volume of a cone is a measure of the amount of space inside the cone.

It is calculated using the formula: V = (1/3) * π * r^2 * h, where V is the volume, r is the radius of the base of the cone, h is the height of the cone, and π is the mathematical constant pi (approximately equal to 3.14).

The volume of the cone is the amount of space inside the cone, and is measured in cubic units (such as cubic centimeters, cubic meters, etc.).

From the diagram, we can see that the radius of the base of the cone is 4 and the height is 8. Plugging these values into the formula, we get:

V = (1/3) * π * 4^2 * 8

V = (1/3) * π * 16 * 8

V = (1/3) * 64π

The volume of this cone is approximately A:2016.

Function g is a transformation of the parent function f(x) = x^2. The graph of g is a translation right 5 units and up 1 unit of the graph of f. Write the equation for g in the form y = ax^2 + bx + c.

Answers

Answer: A transformation of a function such as y = f(x) is a way to change the appearance of its graph by applying certain rules to it. In this case, the graph of function g is a translation right 5 units and up 1 unit of the graph of f.

To find the equation of the transformed function g, we can take the equation of the parent function, which is y = f(x) = x^2 and apply the translation rules (right 5 units and up 1 unit) to it.

The translation right 5 units means that the x-coordinate of each point on the graph of f is increased by 5 units. So this can be written as x = x+5

The translation up 1 unit means that the y-coordinate of each point on the graph of f is increased by 1 units. So this can be written as y = y+1

Substituting x = x+5 and y = y+1 in the equation of the parent function y = x^2 gives the equation of g in the form:

y = (x+5)^2 + 1

So the equation of g is y = (x+5)^2 +1

This equation is a parabola with a vertex that

Which of these is the closest to the population of the city at the end of
1970?

Answers

Answer:

298078.228074

Step-by-step explanation:

we add 6.8% of the population to the city each year

city population in year x + 1 = city population in year x + 6.8% of city population in year x = city population in year x + 0.068 * city population in year x = 1 * city population in year x + 0.068 * city population in year x = 1.068 * city population in year x

we multiply the population by 1.068 each year to get the next year's population

thus, over a period of y years, we would multiply the population by 1.068 y times.

start = 34000 in 1937

difference in years = 1970 - 1937 = 33

final amount = 34000 * 1.068 33 times = 34000 * 1.068^33 = 298078.228074
