Jungle John participates in a reality TV show that features fitness and agility competitions. In order to beat the competitors, John needs to swing from tree A to tree B, completing an arc of at least 60 feet with a central angle of 115∘.
What length of rope (radius) will he need to accomplish this activity?
Round your answer to the nearest foot, and please show your work.

Answers

The  length of rope Jungle John  will he need to accomplish this activity is 30 feet.

How do we calculate?

the formula for arc length is

L = rθ

where L = length of the arc,

r =e radius of the circle,

θ = central angle of the arc in radians.

θ = (115∘/180∘)π = 2.0089 radians

60 feet = r(2.0089 radians)

r = 60 feet / 2.0089 radians

r = 29.85 feet

r is approximated to 30 feet

Therefore, Jungle John will need a rope with a length of at least 30 feet to swing from tree A to tree B and complete an arc of at least 60 feet with a central angle of 115∘.

What is cube and formula of volume of cube?

A cube is a solid three-dimensional shape with 6 square faces, 8 vertices and 12 edges. It is also said to be a regular hexahedral.

The volume V of a cube  is given by the formula V = a^3, where a = the length of one side of the cube. V = 4 ^ 3 = 64 cubic meters or inches ^ 3. The volume of a cube is 64 cubic meters

The total volume of the cheese block is obtained as follows:

V = edge length³ = 8³ = 512 cubic meters

Since the volume of each piece is 1 cubic inch, the total number of pieces is obtained by dividing the total volume by the volume of each piece:

Number of pieces = V / volume per piece = 512 / 1 = 512 pieces

Therefore, when the block is cut into smaller pieces, 512 pieces of cheese remain.

What does an equation mean?

A mathematical statement or relation between two or more numeric values, variable and mathematical operations via equal sign is called an Equation.

How to solve equations in Elimination Method?

Elimination method is a kind of method to solve simultaneous equations in two variables. In elimination method we compare coefficient of one of two variables and in next step we eliminate that variable using addition or subtraction and form another relation with only one variable and find the value for that one variable and then substituting that value initial equation we can get the value of another variable.

Let the rate of first mechanic and second mechanic be x and y per hour respectively.

Sum of the two rates is 135 per hour. So the suitable equation will be,

x+y = 135 ............... (i)

Since they charged together 1650 after working 10 hours by first and 15 hours by second mechanics. So the suitable equation this time will be,

10x+15y = 1650

5(2x+3y) = 1650

2x+3y = 1650/5

2x+3y = 330 ............... (ii)

Multiplying 2 with equation (i) and then subtracting it from equation (ii) we get,

(2x+3y) - 2(x+y) = 330 - 2*135

2x+3y-2x-2y = 330-270

y = 60

Substituting y=60 in equation (i) we get,

x+60 = 135

x = 135-60 = 75

Hence, the rates charged per hour are 75 and 60 per hour respectively.

The possible rule of the polynomial function is f(x) = 1/2(x + 2)(x + 1)²(x - 1)²

Finding the possible rule of the function

From the question, we have the following zeros and multiplicities that can be used to derive the rule of the function

Zeros: x = -2; Multiplicity = 1Zeros: x = -1; Multiplicity = 2Zeros: x = 1; Multiplicity = 2

The possible rule of the function is represented as

f(x) = a(x - zero)^multiplicity

So, we have

f(x) = a(x + 2)(x + 1)²(x - 1)²

The graph passes through (0, 1)

So, we have

a(0 + 2)(0 + 1)²(0 - 1)² = 1

This gives

2a = 1

Divide

a = 1/2

Recall that

f(x) = a(x + 2)(x + 1)²(x - 1)²

So, we have

find slope and y intercept of -5x = 8 - y

Answers

To find the slope and y-intercept of -5x = 8 - y, we need to rearrange the equation into slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

Starting with -5x = 8 - y, we can add y to both sides to get:

-5x + y = 8

Next, we can add 5x to both sides to isolate y:

y = 5x + 8

Now we can see that the equation is in slope-intercept form, where the slope is 5 and the y-intercept is 8.

Therefore, the slope of the equation -5x = 8 - y is 5 and the y-intercept is 8.

Therefore, the volume of Prism B is 727/4 ft³ or 181 3/4 ft³ in mixed number form.

How should mixed numbers be done step-by-step?

Subtract the denominator from the numerator. The quotient should be expressed as a whole number in step 2. Step 3: Enter the denominator and numerator, respectively, as the remainder and the divisor.

We can write: Using the formula for a prism's volume (V = Bh, where B is the base area):

We must determine Prism B's cross-sectional area in order to get the volume of Prism B. By dividing the height equation of prism A by its volume equation, the following result is obtained:

cross-sectional area of Prism A = (Volume of Prism A) / (height of Prism A) = (872/1 ft³) / (6 ft) = 218/3 ft²

Using the scale factor equation for height, we get:

k = (height of Prism A) / (height of Prism B) = (6 ft) / (31/12 ft) = 24/31

Using the scale factor equation for cross-sectional area, we get:

k² = (cross-sectional area of Prism A) / (cross-sectional area of Prism B) = (218/3 ft²) / (cross-sectional area of Prism B)

Solving for the cross-sectional area of Prism B, we get:

cross-sectional area of Prism B = [tex](218/3 ft^2) / k^2 = (218/3 ft^2) / (24/31)^2 = 59/3 ft^2[/tex]

Finally, substituting the height and cross-sectional area of Prism B into the volume equation of Prism B, we get:

Volume of Prism B = (cross-sectional area of Prism B) * (height of Prism B) = [tex](59/3 ft^2) * (31/12 ft) = 727/4 ft^3.[/tex]

Answers

The probability that the employee will arrive between 8:05 a.m. and 8:45 a.m. is 0.8, or 80% when expressed as a percentage.

HOW TO SOLVE THE PROBABILITY ?

To find the probability that the employee will arrive between 8:05 a.m. and 8:45 a.m., we need to calculate the proportion of the total possible time range between 8:00 a.m. and 8:50 a.m. that falls within the specified time interval.

The total time range between 8:00 a.m. and 8:50 a.m. is 50 minutes (8:50 - 8:00 = 50). The time interval between 8:05 a.m. and 8:45 a.m. is 40 minutes (8:45 - 8:05 = 40).

So, the probability that the employee will arrive between 8:05 a.m. and 8:45 a.m. is:

Probability = (Time interval between 8:05 a.m. and 8:45 a.m.) / (Total time range between 8:00 a.m. and 8:50 a.m.)

Probability = 40 minutes / 50 minutes

Probability = 0.8

In this case, creating a new numerator just requires multiplying the numerator by the full number. After that, the original numerator becomes the new denominator.

3*5/2 = 15/2

Most people prefer to express results in decimals, and all you have to do to do so is divide the numerator by the denominator:

15/2 = 7.5

Answers

Answer:

We can use the formula for compound interest to calculate the amount of interest Brian will earn:

A = P (1 + r/n)^(nt)

where:

A = the total amount after 7 years

P = the principal amount ($9,411)

r = the annual interest rate (3.48%)

n = the number of times the interest is compounded per year (52 weeks in a year, so n = 52)

t = the number of years (7)

Plugging in the values, we get:

A = $9,411 (1 + 0.0348/52)^(52*7)

A = $9,411 (1.0006692302021135)^364

A = $12,471.36

To find the amount of interest earned, we can subtract the principal amount from the total amount:

Interest = $12,471.36 - $9,411 = $3,060.36

Therefore, Brian will earn $3,060.36 in interest after 7 years. Rounded to the nearest cent, this is $3,060.37.

Using limits the value of k is c √2

What is the limit of a function?

The limit of a function is the valuer the function tends to as the dependent variable tends to a particular value.

Given that the limit lim n → ∞ [x√(x + 1)[1 - √(2x + 3)]/(7 - 6x + kx²) = - 1, we desirte to find the value of k.

So, we proceed as follows

lim n → ∞ [x√(x + 1)[1 - √(2x + 3)]/(7 - 6x + kx²) = - 1

Factorizing out √2x, we have that

lim n → ∞ [x√(x + 1)[1 - √(2x√(1 + 3/√(2x)]/(7 - 6x + kx²) = - 1

lim n → ∞ [x√(x + 1)√(2x[1/√(2x - √(1 + 3/√(2x)]/(7 - 6x + kx²) = - 1

Also, factorizing out √x, we have that

lim n → ∞ [x√x√(1 + 1/√x)√2x[1/√(2x - √(1 + 3/√(2x)]/(7 - 6x + kx²) = - 1

lim n → ∞ [x√x√2x√(1 + 1/√x)[1/√(2x - √(1 + 3/√(2x)]/(7 - 6x + kx²) = - 1

lim n → ∞ [x√2x√(1 + 1/√x)[1/√(2x - √(1 + 3/√(2x)]/(7 - 6x + kx²) = - 1

lim n → ∞ [√2x²√(1 + 1/√x)[1/√(2x - √(1 + 3/√(2x)]/(7 - 6x + kx²) = - 1

Factorizing x² from the denominator, we have that

lim n → ∞ [√2x²√(1 + 1/√x)[1/√(2x - √(1 + 3/√(2x)]/x²(7/x² - 6/x + k) = - 1

lim n → ∞ [√2√(1 + 1/√x)[1/√(2x - √(1 + 3/√(2x)]/(7/x² - 6/x + k) = - 1

Now substituting x = ∞ into the equation, we have that

[√2√(1 + 1/√∞)[1/√(2∞ - √(1 + 3/√(2∞)]/(7/∞² - 6/∞ + k) = - 1

[√2√(1 + 0)[0 - √(1 + 0]/(0 - 0 + k) = - 1

[√2√(1)[- √1]/k = - 1

[√2(1)[- 1]/k = - 1

-√2/k = - 1

k = -√2/-1

k = √2

So, the value of k is c √2

A sum of money has a value of$3000 eight-

een months from now. If money is worth 6%

compounded monthly, what is its equivalent value


(a) now?

(b) one year from now?

(c) three years from now?​

Answers

Answer:

We can use the formula for compound interest to solve this problem:

A = P(1 + r/n)^(nt)

where A is the future value, P is the present value, r is the interest rate, n is the number of times the interest is compounded per year, and t is the time period in years.

(a) To find the present value of the money, we need to solve for P in the formula above. We are given that A = $3000 and t = 18/12 = 1.5 years. The interest rate is 6% per year, compounded monthly, which means n = 12. Substituting these values into the formula, we get:

3000 = P(1 + 0.06/12)^(12*1.5)

Simplifying and solving for P, we get:

P = 3000 / (1 + 0.06/12)^(12*1.5)

P = $2,572.39

Therefore, the equivalent value of the money now is $2,572.39.

(b) To find the equivalent value of the money one year from now, we need to calculate the future value of $1 after one year, and then multiply it by the present value we found in part (a). The future value of $1 after one year, at 6% per year, compounded monthly, is:

FV = 1*(1 + 0.06/12)^(12*1)

FV = $1.06168

Multiplying this by the present value we found in part (a), we get:

$2,572.39 * $1.06168 = $2,735.92

Therefore, the equivalent value of the money one year from now is $2,735.92.

(c) To find the equivalent value of the money three years from now, we need to calculate the future value of $1 after three years, and then multiply it by the present value we found in part (a). The future value of $1 after three years, at 6% per year, compounded monthly, is:

FV = 1*(1 + 0.06/12)^(12*3)

FV = $1.19102

Multiplying this by the present value we found in part (a), we get:

$2,572.39 * $1.19102 = $3,066.63

Therefore, the equivalent value of the money three years from now is $3,066.63.

Scott's employer pays 55% of his health insurance premium and deducts the

Your Answer:

Answers

Answer:

To calculate how much is deducted from Scott’s paycheck, we need to first find out how much his employer pays for his health insurance premium.

55% of the annual premium is covered by the employer, so we can calculate this as:

0.55 x $20,969 = $11,532.95

Therefore, Scott’s employer pays $11,532.95 towards his health insurance premium.

To find out how much is deducted from Scott’s paycheck, we need to divide the remaining 45% of the premium by the number of pay periods in a year. Since Scott is paid biweekly, he receives 26 paychecks in a year.

45% of the annual premium is not covered by the employer, so we can calculate this as:

0.45 x $20,969 = $9,437.55

To find out how much is deducted from each biweekly paycheck, we can divide $9,437.55 by 26:

$9,437.55 ÷ 26 = $363.75 (rounded to the nearest cent)

Therefore, Scott’s employer pays $11,532.95 towards his health insurance premium and $363.75 is deducted from each of his biweekly paychecks for health insurance.
