Answer:

No, a trapezoid is not a rectangle.

This is because trapezoids by definition have only one pair of parallel sides while rectangles must have at least two sets of opposite parallel sides. Also, trapezoids do not have 90 degrees at every angle like rectangles do.

(a) The number of ways to choose 5 colors without replacement from 15 distinct colors, where the order of the choices is not relevant, is given by the combination formula. This is denoted as "15 choose 5," or 15C5, which is equal to 3,003.

(b) If the order of the choices is relevant, then the number of ways to choose 5 colors without replacement from 15 distinct colors is given by the permutation formula. This is denoted as "15 permute 5," or 15P5, which is equal to 3,003,600.

In part (a), we use the combination formula because we want to know the number of ways to choose 5 colors from 15 distinct colors without regard to the order of the choices. This formula is given by nCr = n!/(r!(n-r)!), where n is the number of items to choose from, and r is the number of items to choose. In this case, n = 15 and r = 5, so we have 15C5 = 15!/(5!(15-5)!) = 3,003.

In part (b), we use the permutation formula because we want to know the number of ways to choose 5 colors from 15 distinct colors, where the order of the choices matters. This formula is given by nPr = n!/(n-r)!, where n is the number of items to choose from, and r is the number of items to choose. In this case, n = 15 and r = 5, so we have 15P5 = 15!/10! = 3,003,600.

Overall, the key difference between part (a) and part (b) is whether or not the order of the choices matters. If the order doesn't matter, we use the combination formula (nCr), and if the order does matter, we use the permutation formula (nPr).

The result of the equation 4 x + 2 + x = x – 19 is - 5.25.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

There are two kinds of equations: identities and conditional equations. An identity is true for all values of the variables.

Given equation -

4 x + 2 + x = x – 19

Simplify the equation

5x + 2 = x - 19

5x - x = -19 - 2

4x = -21

x = -21 / 4

x = -5.25

Hence, -5.25 is the answer to the equation 4 x + 2 + x = x - 19.

The correct option is;

A(-12, -19) and B(20, 45) matches with point C(6, 52) such that ∠ABC = 90°

Step-by-step explanation:

Given slope AB =

A point is perpendicular to two points

Where A(3, 3), B(12, 6) C(6, 52) we have;

Slope AB = (3 - 6)/(3 - 12) = -3/(-9) = 1/3

Slope BC = -3

y - 12 = -3(x - 6)

y = -3x + 18 + 12 = -3x + 30

A(-10, 5) and B(12, 16)

Slope AB = (5 - 16)/(-10 - 12) = -11/(-22) = -1/2

Slope BC = 2

y - 16 = 2(x - 12)

y = 2x - 24 + 16 = 2x - 8

A(-8, 3) and B(12, 8)

Slope AB = (3 - 8)/(-8 - 12) = -5/(-20) = -1/4

Slope BC = -4

y - 8 = -4(x - 12)

y = -4x + 48 + 8 = -4x + 56

A(12, -14) and B(-16, 21)

Slope AB = (-14 - 21)/(12 + 16) = -35/(28)

Slope BC = 28/35

y - 21 = 28/35(x + 16)

y = 28/35x + 28/35*16 + 21 = -4x + 56

A(-12, -19) and B(20, 45)

Slope AB = (-19 - 45)/(-12 - 20) = 2

Slope BC = -1/2

y - 45 = -1/2(x - 20)

y = -1/2x + 10 + 45 = -1/2x + 55

Which corresponds with the point C(6, 52)

A(30, 20) and B(-20, -15)

Slope AB = (20 + 15)/(30 + 20) = 35/50 = 7/10

Slope BC = -10/7

y + 15 = -10/7(x + 20)

y = -10/7x - 10/7*20 - 15 = -10/7x - 305/7

Answer:

A(3, 3) and B(12, 6)  =  C(16, -6)

A(-10, 5) and B(12, 16) = C(18, 4)

A(-12, -19) and B(20, 45) =  C(6, 52)

A(12, -14) and B(-16, 21) =C(-11, 25)

Step-by-step explanation:

a. ln(7x) can be expanded as ln(7) + ln(x). b. ln(x + 3) remains as it is, since it cannot be simplified further. c. ln(x^8) can be expanded as 8ln(x). d. 15,000ln(xy^4) can be expanded as ln(x) + 4ln(y) + ln(15,000).

a. To expand the logarithmic expression ln(7x), we can use the property of the natural logarithm that states ln(ab) = ln(a) + ln(b).

Therefore, ln(7x) can be expanded as ln(7) + ln(x).

b. Similarly, the logarithmic expression ln(x + 3) can be expanded using the property ln(ab) = ln(a) + ln(b).

Hence, ln(x + 3) remains as it is since we cannot simplify it further.

c. Expanding the logarithmic expression ln(x^8) can be done using the property ln(a^b) = b * ln(a).

Thus, ln(x^8) becomes 8 * ln(x).

d. Expanding the logarithmic expression 15,000ln(xy^4) can be done by applying the property ln(ab) = ln(a) + ln(b).

Therefore, 15,000ln(xy^4) can be expanded as 15,000[ln(x) + ln(y^4)].

The constant of proportionality from the proportional relationship is 3/2

A proportional relationship is a mathematical relationship between two variables in which their ratio is always equal. In other words, if x and y are in a proportional relationship, then y/x is always equal to a constant value, called the constant of proportionality. This can be expressed mathematically as y = kx, where k is the constant of proportionality and x and y are the variables in the relationship.

To determine the constant of proportionality, we need to use the proportional relationship given.

y = kx

k = constant of proportionality

3/8 = k(1/4)

Solve for k

k = [(3/8) / (1/4)]

k = 3/2

Step-by-step explanation:

The magazines are sold at a discount. Discount reduces the price of the good

If the magazines are sold at 20%, the magazine's price would be 80% (100% - 20%) of the original price

let a represent price of the magazine before the discount

This equation represents price of the magazine after the discount

0.8 x a = $72

Divide both sides by 0.8 and find a

a = $90

A sample size of 753 would be required to create the desired 98% confidence interval with an accuracy of within 3.0%.

To determine the sample size needed to create a 98% confidence interval with an accuracy of 3.0%, we can use the formula:

n = (z^2 * p * (1-p)) / E^2

where:

n = sample size
z = z-score for the desired confidence level (98% = 2.33)
p = estimated population proportion (0.40)
E = desired margin of error (0.03)

Plugging in the values, we get:

n = (2.33^2 * 0.40 * (1-0.40)) / 0.03^2
n = 623.22

Rounding up to the nearest whole number, we get a sample size of 624. Therefore, the person would need to use a sample size of 624 in order to create a 98% confidence interval with an accuracy of 3.0% for the unknown population proportion.
To create a 98% confidence interval for an unknown population proportion with an accuracy of within 3.0% and an estimated population proportion of 0.40, you'll need to determine the required sample size. You can use the following formula for sample size calculation:

n = (Z^2 * p * (1-p)) / E^2

where n is the sample size, Z is the Z-score associated with the desired confidence level (98% in this case), p is the estimated population proportion (0.40), and E is the margin of error (3.0% or 0.03).

For a 98% confidence level, the Z-score is approximately 2.33. Plugging the values into the formula:

n = (2.33^2 * 0.40 * (1-0.40)) / 0.03^2

n ≈ 752.07

Answer:

Hope this helps and have a nice day

Step-by-step explanation:

To find the value of n in the equation 1/n = x^2 - x + 1, given that the roots are unequal and real, and n > 0, we can analyze the properties of the equation.

The equation 1/n = x^2 - x + 1 can be rearranged to the quadratic form:

x^2 - x + (1 - 1/n) = 0

Comparing this equation to the standard quadratic equation form, ax^2 + bx + c = 0, we have:

a = 1, b = -1, and c = (1 - 1/n).

For the roots of a quadratic equation to be real and unequal, the discriminant (b^2 - 4ac) must be positive.

The discriminant is given by:

D = (-1)^2 - 4(1)(1 - 1/n)

= 1 - 4 + 4/n

= 4/n - 3

For the roots to be real and unequal, D > 0. Substituting the value of D, we have:

4/n - 3 > 0

Adding 3 to both sides:

4/n > 3

Multiplying both sides by n (since n > 0):

4 > 3n

Dividing both sides by 3:

4/3 > n

Therefore, for the roots of the equation to be unequal and real, and n > 0, we must have n < 4/3.

Therefore, Laura will earn $495 if she works 50 hours this week, taking into account the time-and-a-half overtime pay for any hours worked beyond 40.

To calculate Laura's earnings for the week, we need to consider her regular pay rate and the overtime pay for any hours worked beyond 40.

Laura earns $9 per hour, so her regular pay rate is $9.

Let's calculate her earnings for the week:

Regular hours worked: 40 hours

Overtime hours worked: 50 hours - 40 hours = 10 hours

Regular pay for 40 hours = 40 hours * $9/hour = $360

Overtime pay for 10 hours = 10 hours * ($9/hour * 1.5) = $135

a) The cost of the stereo system is $4,760.

b) The total amount of interest paid is $1,760.

To find the cost of the stereo system, we need to calculate the sum of the down payment and the total of monthly payments over 4 years. The down payment is $400, and the monthly payment is $90 for 48 months (4 years). Thus, the total cost of the stereo system is $400 + ($90 × 48) = $4,760.

To calculate the total amount of interest paid, we need to subtract the initial principal amount (down payment) from the total cost of the stereo system. The initial principal amount is $400, and the total cost is $4,760. Therefore, the total interest paid is $4,760 - $400 = $1,760.

Answer:

A. Slope = 4 and y-intercept  = 3

Answer:

The slope also increases

Step-by-step explanation:

The slope of a function is the ratio of change in y to change in x. For an exponential function f(x) = e^x, the slope of the function is equal to the function, i.e slope = e^x.

For a function represented by \(y=2^x\), this is an exponential function representing growth, the slope of  \(y=2^x\) is also  \(2^x\), therefore as the value of x increases, the value of the slope also increases.

At x = 1, slope = 2^1 = 2, At x = 4, slope = 2^4 = 16.
