The doubling time will be 4.4 years for a city is population is growing by 17% per year.

It's time to double down on the time-doubling equation (pun intended). On the assumption that the growth in amount remains constant from one period to the next, the equation is as follows:

Doubling time = log 2 / log (1 + increase)

It has given that the population of the city is growing back 17% per year.

Doubling time = log 2 / log (1 + increase)

Doubling time = log 2 / log (1 + 17/100)

[tex]\mathrm{Apply\:log\:rule}:\quad \frac{\log _c\left(b\right)}{\log _c\left(a\right)}=\log _a\left(b\right)[/tex]

[tex]=\log _{1+\frac{17}{100}}\left(2\right)[/tex]

Doubling time = 4.41484

Round to the nearest tenth decimal.

Doubling time = 4.4

Thus, the doubling time will be 4.4 years for a city is population is growing by 17% per year.

If you do not pay anything on that loan during the year and assuming there is no compounding, the total sum owing is $1,216.50.

When money is given to someone else with the knowledge that it would be returned with interest, it is referred to as a loan. . Lenders will consider a borrower's income, credit rating, and level of debt before deciding to grant a loan.

Money borrowed from a bank or other financial organization is known as a loan. The borrower consents to repay the loan's principal plus interest. There are many different kinds of loans, such as auto loans, student loans, and mortgages.

The amount is 1000(1 + 0.0765), or 1000 x 1.0765, or 1,076.50.

For every 4 beef cattle there is 3 dairy cattle. For 24 dairy cattle there will be 32 beef cattle as per the given ratio of 3:4.

An ordered pair of numbers a and b, written as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could write the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls). The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two things.

Here,

a. No for every 4 beef cattle there is 3 dairy cattle.

b. 4/3=x/24

Answer:

  $920

Step-by-step explanation:

You want to know the original price of a suit on sale for $331.20, if that price represents a 64% discount.

The discounted price is found by subtracting the amount of the discount from the original price. That amount is the product of the original price and the rate of the discount.

  discounted price = price - (discount)·(price)

  discounted price = price · (1 - discount)

The the original price is ...

  price = (discounted price)/(1 - discount) = $331.20/(1 -0.64)

  price = $920

The original price of the suit was $920.00.

Step-by-step explanation:

a) The penalty Lorna must pay for the late payment of her real estate tax is $26.50.

b) The total amount Lorna must pay on February 27 is $2,037.38.

The penalty for unpaid taxes is computed by determining the number of days the taxes remained unpaid.

Then the penalty rate is applied to the unpaid taxes multiplied by the number of days taxes were outstanding, divided by 365 days.

The product of the above multiplication and division operations is the penalty.

Outstanding real estate tax = $2,010.88

Due date for the tax = December 14, 2017

Payment date for the tax = February 27, 2018

Number of days, tax outstanding = 74 days

Penalty rate for late payment = 6.5%

Penalty = $26.50 ($2,010.88 x 6.5% x 74/365)

Total payment on February 27 = $2,037.38 ($2,010.88 + $26.50)

Step-by-step explanation:

The equation of line parallel to 2x +3y = 9 and passing through the point (6,4) is 3y + 2x = 24

Gradient or slope is the ratio of the change in y to the change in x between two points in a line.

Gradient tells how steep a line is. A perfectly vertical or horizontal line has no slope.

2x + 3y = 9

making y the subject,

3y = 9 - 2x

y = 9/3 -2x/3

Comparing the above equation, with equation of a straight line, y = mx + c

m, which is slope = -2/3

The new line will also have a slope of -2/3 because they are parallel.

Equation for new line,

y-[tex]y_{1}[/tex] / x - [tex]x_{1}[/tex] = slope

The new point is (6,4)

y - 4 / x -6 = -2/3

By cross multiplying

3(y-4) = -2(x - 6)

3y - 12 = -2x + 12

3y + 2x = 24

g(-x) = 3(-x)³ + (-x) = -3x³ - x

so , this is odd function .

Option (b)

the transformation is given as g(2x)

g(-2x) = 3(-2x)³ + (-2x) = -24x³ - 2x

-g(2x) = -{3(2x)³ + (2x)} = -( 24x³ + 2x ) = -24x³ - 2x

so , this is  odd function .

Option (c)

the transformation is given as g(x)-3

(g(-x) - 3) =  3(-x)³ + (-x) - 3 = -3x³-x-3

Confidence interval gives the probability that the unknown parameter will fall within a stated range

The confidence interval is constructed using the formula

confidence interval = x-bar ± z(s/√n)

mean, x-bar = 92.1 min

standard deviation, s = 40.5 min

sample size, n = 23

confidence level = 98%

z score, z

For sample size less than 30, n < 30. t scores are used

degree of freedom, df = n - 1 = 23 - 1 =22

t score for 98% confidence level and dt of 22 = 2.509

substituting into the formula

= x-bar ± t(s/√n)

= 92.1 ± 2.509 (40.5 / √23)

= 92.1 ± 21.188

The required angles of x and y are x = 65° and y = 25°

Given is a triangle which is right angled

Thus the sum of the right angled triangle is 180 degrees

So we will write

y° + x + 90 = 180 [ angle sum property of the triangle ]

90 + x + y = 180

let the above equation be considered as equation 1

Since two sides are equal

thus the other angle will also be x°

Also the angle adjacent to 40° can be found out by linear angle property

thus according to this :

x + x + ( 90 - 40 ) = 180 °

2x + 50 = 180

thus subtracting 50 on both sides we get

2x = 130

x = 65°

Thus by equation 1

we can rewrite it as

y + x + 90 = 180

65 + 90 + y = 180

155 + y = 180

this implies y = 180 - 155

y = 25°
