Answer:

[tex]P_4 = 7604.08[/tex]

Step-by-step explanation:

If the population increases at a rate of 4% per annum, then:

In year 1:

[tex]P_1 = P_0 + 0.04P_0[/tex]

Where [tex]P_0[/tex] is the initial population and [tex]P_n[/tex] is the population in year n

In year 2

[tex]P_2 = P_1 + 0.04P_1[/tex]

It can also be written as:

[tex]P_2 = P_0 + 0.04P_0 + 0.04 (P_0 + 0.04P_0)[/tex]

Taking out common factor [tex]P_0[/tex]

[tex]P_2 = (1 + 0.04) (P_0) + 0.04P_0 (1 + 0.04)[/tex]

Taking out common factor (1 + 0.04)

[tex]P_2 = (1 + 0.04) (P_0 + 0.04P_0)[/tex]

Taking out again common factor [tex]P_0[/tex]

[tex]P_2 = (1 + 0.04) (1 + 0.04) P_0[/tex]

Simplifying

[tex]P_2 = P_0 (1 + 0.04) ^ 2[/tex]

So

[tex]P_n = P_0 (1 + 0.04) ^ n[/tex]

This is the equation that represents the population for year n

Then, in 4 years, the population will be:

[tex]P_4 = P_0 (1 + 0.04) ^ 4\\P_4 = 6500(1 + 0.04) ^ 4\\P_4 = 7604.08[/tex]

Answer:

∠4 and ∠12

A is correct

Step-by-step explanation:

Parallel lines r and s are cut by two transversals, parallel lines t and u

r || s and t || u

We are four parallel line. Two parallel line cuts two another parallel line.

Angle 8 is form by intersection of s and t line.

Corresponding angle: When two parallel lines are crossed by transversal line,  the angles at matching corners are called corresponding angles.

For angle 8, t || u with s is transveral line.

Thus, ∠8 = ∠12  (By definition of corresponding angle)

For angle 8, s || r with t is transveral line.

Thus, ∠8 = ∠4  (By definition of corresponding angle)

Hence, ∠4 and ∠12 are corresponding angle of ∠8

The value of F(8) is 64.

Given that,

Based on the above information, the calculation is as follows:

We are given: Triangle ABC sides, AB = x, BC = y and CA = 2x.

Another triangle MNO whose vertices M,N and O correspond to A,B,C respectively.

Therefore, AB corresponding to sides MN , BC corresponding to sides NO and CA corresponding to sides OM.

Also, we are given " A similarity transformation with a scale factor of 0.5 Maps ABC to MNO".

That means triangle ABC is dilated by a factor of 0.5.

Each side of the triangle MNO is 0.5 times(half) of Triangle ABC.

We could also say that each side of Triangle ABC is two times of sides of triangle MNO.

We are given side OM = 5 units.

CA = Times of OM = 2 * 5 = 10 units.

CA = 2x = 10 units or 2x=10.

Dividing both sides by 2, we get

[tex]\frac{2x}{2}=\frac{10}{2}[/tex]

x=5.

AB = x.

Therefore, AB = 5 units.

2a. 10 h 20 min 41.4 sec

2b. 361.6 km

5a. $8

5b. 444.5 km

5c. 46 h 13 min 20.9 sec

5d. $160

Step-by-step explanation:

Each of these problems expresses a proportion and asks you to find a missing value. You are given, for example, value 1 and related value 1. You are asked to find value 2 that corresponds to related value 2.

Solving the Proportion

Expressed as a proportion, this looks like ...

... (value 1)/(related value 1) = (value 2)/(related value 2)

If you multiply both sides of this equation by related value 2, you can find value 2.

... (related value 2)/(related value 1)×(value 1) = value 2

Another way to think about it

I like to think of the related values as making a fraction. If the related value 2 is larger than related value 1, the fraction is greater than 1 and the value 2 will be larger than value 1. (This realization can serve as a check on your answer.)

1a. related value 2 = 168 km. This is the value for which you want to find value 2, the number of liters of gasoline. related value 1 has the same units as related value 2 (km), and value 1 has the same units as value 2 (liters).

Then the fraction of interest is (168 km)/(468 km), and it multiplies 117 L. The result is ...

... (168/468)×(117 L) = 42 L

1b. (10 h)/(4 h)×(138 mi) = 345 mi

2a. (180 mi)/(261 mi)×(15 h) ≈ 10.3448 h

2b. (4 h)/(5 h)×(452 km) = 362.6 km

You may have noticed that I keep the units with the numbers. When the same units are in the numerator and denominator, they cancel—the way any common factors cancel. The remaining units will be the units of the answer. This practice of keeping units with numbers can help ensure you're using the right numbers for the right purpose. If the units don't work out, your math has an error.

5a. (2 lb)/(50 lb)×$200 = $8

5b. (7 h)/(6 h)×381 km = 444.5 km

5c. (459 km)/(427 km)×(43 h) ≈ 46.2225 h

5d. (20 kg)/(11 kg)×$88 = $160

85% is the answer, because it is an 85% chance of him passing, now the chance of him passing twice in a row would be 72.25% because you would multiply 0.85 and 0.85 together.

Answer:

x=-2

Step-by-step explanation:

We are given an equation as

[tex]\frac{4-3x}{2} =5[/tex]

and asked to solve for x

Simplify by multiplying both sides by 2.  This will get rid of fraction on left side.

4-3x = 10

Grouping like terms by taking 4 to right side

we get right side 10-4 = 6

-3x = 6

To get exact value of x, we divide by -3 on both the sides

x = 6/-3 = -2

Since this is an equation, we get a single value for x

x=-2

and answer is -2

Given fractional expression:

{(4-3x)/2} = 5

→ 4-3x = (5)2

→ 4-3x = 10

→ -3x = 10-4

→ -3x = 6

Therefore, x = -(6/3) = -2

Step-by-step explanation:

(  -2x³ + x - 5) × ( x3 - 3x - 4)

= ( -2x³)×( x3 - 3x - 4) +(x)×( x3 - 3x - 4) - (5)( x3 - 3x - 4)

= - 2x^6  +6x^4 +8x³ + x^4 - 3x² -4x - 5x³ +15x + 20

The population of the first town decreases at a rate of 600 people per year, and is predicted to be 2,100 in 2016. The town with an initial population of 75,000 grows at a linear rate, represented by the function P(t) = 75000 + 2500t, with the population expected to reach 100,000 after 10 years.

For the first part of your question regarding the town's decreasing population, we need to establish a rate of decrease. The town's population went from 5,900 in 2010 to 4,700 in 2012—this is a decrease of 1,200 over two years, or 600 people per year. Therefore, we can predict that the population will continue to decrease by 600 people per year. In 2016, this suggests the population would be 4,700 (population in 2012) - 600*4 (4 years from 2012 to 2016), which equals 2,100. For identifying the year when the population will reach 0, we use the same rate and find it by using the formula (current population / rate of decrease) + current year. As for the part about the town with an initial population of 75,000 growing at a constant rate, we can model this as a linear function such as P(t) = 75000 + 2500t. This equation states that the population at any given year is the initial population plus the annual growth times the number of years since the model began. In terms of the graph of this function, the y-intercept represents the initial population, while the slope is the constant rate of growth. The model expects the population to reach 100,000 after (100,000 - 75,000) / 2,500  = 10 years.

SInce you need 1.5 feet of overhang, add 3 feet to each axis dimension 1.5 on each side):

Minor Axis = 18 + 3 = 21 feet

Major axis = 25 + 3 = 28 feet

The area of an ellipse is found by multiplying half the minor axis by half the major axis by PI.

1/2 minor axis = 21 / 2 = 10.5

1/2 major axis = 28 / 2 = 14

Using 3.14 for PI

Area = 10.5 x 14 x 3.14 = 147 x 3.14 = 461.6 sq ft

This problem is not as simple as it may appear at first. The area of an ellipse is ...

... A = πab

where a and b are the semi-axes.

Here, it looks like you're expected to choose these to be 1.5 ft longer than half the given axes, so the area of the pool cover is about ...

... A = π(9 ft + 1.5 ft)(12.5 ft +1.5 ft)

... A = 147π ft² ≈ 461.8 ft²

_____

However, adding 1.5 ft of material to an ellipse results in a shape that is not an ellipse, but is slightly larger than the ellipse with the dimensions used above. The area of that may be about 462.5 ft² (found numerically).

dy/dx = 6x² +4 . . . . . using the power rule

dy/dt = (dy/dx)×(dx/dt) = (6(4²) +4)×2

dy/dt = 200 . . . at x=4

The term sin(x+[7pi/4]) can be rewritten in terms of sin(x) and cos(x) using the formula for sine of the sum of two angles. Given A = x and B = 7pi/4, the equation can be simplified to sin(x + [7pi/4]) = sin(x)(√2/2) - cos(x)(√2/2).

To rewrite the term sin(x+[7pi/4]) in terms of sin(x) and cos(x), we can use the formula for sine of the sum of two angles. The formula is given by:

sin(A + B) = sinAcosB + cosAsinB

Substituting our given values into this formula, where A = x and B = 7pi/4, we get:

sin(x + [7pi/4]) = sin(x)cos(7pi/4) + cos(x)sin(7pi/4)

Note that cos(7pi/4) = √2/2 and sin(7pi/4) = -√2/2. Therefore:

sin(x + [7pi/4]) = sin(x)(√2/2) - cos(x)(√2/2)

Answer:

b. Your answer is appropriate.

c. The decimals can be eliminated by multiplying by 100. (You can also add 0.14 to the problem, adding .01 to each individual price and 0.14 to the total. This will make the second equation be 12x +25y = 246, which makes the numbers slightly easier to work with.) Unfortunately, there don't seem to be any common factors that would reduce the size of the numbers.

Step-by-step explanation:

a. We assume you're finding quantities of shirts and pants for a purchase of 14 total items costing $245.86. If so, your equations are appropriate.

b. The solution for one variable or the other can be found in 6 arithmetic operations using your suggested method. Any other method takes as many or more. (Multiplying the first equation by -11.99 and adding to the second gets you the equivalent of substituting for x in as many operations.)

Graphing can be quick and easy with the right tool. Since you know the solutions are integers, just about any graphing tool will get you close enough.

Another method (using only 5 arithmetic operations) is to calculate the average price of an item as 245.86/14, then figuring the ratio of the difference from the lower price to the total difference in price. Multiplying this ratio by the number of items gives the number of the higher-priced item (pants). (245.86/14 -11.99)/(24.99 -11.99)·14 = 6 This method treats the problem as a "mixture" problem, finding the numbers of each consitutuent that make the average come out what it is.

c. See above for how to simplify the numbers. Done properly, the answer is not changed. (Some people don't work well with decimals or fractions, so like to see those eliminated from the problem. Some folks work better with small integers than with large ones, so like to see the numbers be made as small as possible.)

x = [tex]\frac{y}{c}[/tex] - b

divide both sides by c

x + b = [tex]\frac{y}{c}[/tex] ( subtract b from both sides )

x = [tex]\frac{y}{c}[/tex] - b

The equation solved for x is x = y/c - b.

Two or more expressions with an equal sign are defined as an equation.

The given equation is y = c(x + b).

y = c(x + b)

y/c = x + b

y/c - b = x

Or, x = y/c - b

Hence, the equation solved for x is x = y/c - b.

A fraction with 9 as a denominator is a repeating 1-digit decimal with the decimal digit being the numerator of the fraction.

A fraction with 11 as a denominator is a repeating 2-digit decimal with the two digits being 9 times the numerator of the fraction.

1/8 = 0.125, so any multiple of 1/8 is that multiple of 0.125.

To convert 5/9 - 3/8 - 3/11 into a decimal, you find a common denominator (792), subtract the numerators, resulting in -73/792, and then divide the numerator by the denominator to find the decimal, which is -0.0922.

Quite often, the CD will earn more interest—even if you have to pay a penalty for early withdrawal.

_____

For example, my local credit union offers 0.10% interest on passbook savings and 1.46% interest on a 4-year CD. One of my local banks offers 0.01% interest on passbook savings, and 0.60% on a 4-year CD.

A CD (Certificate of Deposit) generally offers a higher interest rate than a passbook savings account, which may lead to a greater return on investment. But it has a drawback where money cannot be withdrawn without penalty until a set time period ends.

The primary advantage of a CD (Certificate of Deposit) over a passbook savings account is typically a higher interest rate. A CD is a type of timed deposit, meaning that the money is typically put in the bank for a fixed amount of time. During this time, the interest rate is usually higher than that of a typical savings account, allowing for a greater return on the initial investment. Unlike a passbook savings account, however, you cannot withdraw money from a CD without penalty until the time period ends, which in this case is four years. This is an important consideration for Beth and Mark.
