The perimeter of a rectangle is 28 cm. Which of the following express the area of the rectangle in terms of the width x?

Answers

Answer 1

Answer:

14x−x

2

Step-by-step explanation:

Perimeter is 2x + 2y = 28 (y is the length BTW)

To find y, transfer equations

28-2x=2y

Divide both sides by 2

14-x = y

Now you have your length in terms of x

Multiplt length and width

x(14-x)

14x - x {}^{2}14x−x

find the following arc measures

find the following arc measures

Answers

The measure of the angles are;

<KL = 23 degrees

m<LON is 23 degrees

m<OM = 113 degrees

m<KNL = 23 degrees

m<NL = 157 degrees

How to determine the measures of the arc

To determine the measures of the arc, we need to note the following;

Angles on a straight line is equal to 180 degreesAngle at right angle is equal to 90 degrees

From the information shown in the diagram, we have;

<KL +<KM = 90 degrees

Now, substitute the values

<KL + 67 = 90

collect like terms

<KL = 23 degrees

m<LON and <KL are corresponding angles

Then, m<LON is 23 degrees

m<OM = m<LON + 90 degrees

Substitute the values

m<OM = 113 degrees

m<KNL = 23 degrees

m<NL = 90 + <LM

Substitute the values

m<NL = 157 degrees

7. The current average cost of gas in Italy is €1.726 Euro per liter. What is this cost in
U.S. Dollars per gallon? Use your answer to Problem #6b and the fact that there are

75

Answers

a. At the current exchange rate, €1 Euro is worth more than $1 U.S. This is because 1 Euro is equivalent to $1.13 U.S. (as given in the problem), which means that for every one dollar, you would receive less than one Euro in exchange. Therefore, €1 Euro is worth more than $1 U.S.

b. To fill in the blanks, we need to use the given conversion rate of €1 Euro = $1.13 U.S. and reciprocate it to find $1 U.S. ≈ €0.885 Euro. Using this conversion rate, we can find that:

$1 U.S. ≈ €0.885 Euro
€1 Euro ≈ $1.13 U.S.

c. To determine whether the jacket is cheaper when priced in Mexican Pesos, we need to convert the price to U.S. dollars using the given exchange rate of $1 U.S. = ₱20.66 Mexican Pesos.

The price of the jacket in Mexican Pesos is ₱2,000. To convert this to U.S. dollars, we divide by the exchange rate:

₱2,000 ÷ 20.66 = $96.89 U.S.

Since $96.89 U.S. is less than $125 U.S. (the price of the jacket in the first website), the jacket priced in Mexican Pesos is cheaper.

7. To convert from Euro per liter to U.S. Dollars per gallon, we need to use the conversion factors from Problem 6b and the fact that there are approximately 3.785 liters in one gallon. First, we can convert from Euro per liter to U.S. dollars per liter by multiplying the cost in Euro per liter by the conversion rate:

€1.726 Euro/L × $1.13 U.S./€1 Euro ≈ $1.95 U.S./L

Then, we can convert from US dollars per liter to U.S. dollars per gallon:

$1.95 U.S./L ÷ 3.785 L/gallon ≈ $0.52 U.S./gallon

Therefore, the cost of gas in Italy is approximately $0.52 U.S. per gallon.
a. To determine which is worth more, we need to compare the exchange rates. If €1 Euro is worth more than $1 U.S., then the Euro is worth more. If $1 U.S. is worth more than €1 Euro, then the dollar is worth more. As of the given exchange rate, €1 Euro is worth less than $1 U.S., so $1 U.S. is worth more.

b. To fill in the blanks, we can use the given exchange rate of €110.50 Euro = $125 U.S.:

$1 U.S. ≈ €0.884 Euro

€1 Euro ≈ $1.129 U.S.

c. To determine if ₱ 2,000 Mexican Pesos is cheaper than $125 U.S., we need to convert the price in Mexican Pesos to U.S. dollars. We can use the exchange rate provided:

$1 U.S. ≈ ₱20.66 Mexican Pesos

So, ₱ 2,000 Mexican Pesos is:

₱ 2,000 / ₱20.66/$1 U.S. = $96.89 U.S.

Since $96.89 U.S. is less than $125 U.S., the jacket on the other site is cheaper.

d. To determine the cost of gas in U.S. dollars per gallon, we need to convert the cost in Euros per liter to U.S. dollars per gallon. We can use the exchange rate:

$1 U.S. ≈ €0.884 Euro

There are 0.26 gallons in 1 liter, so we can convert the cost per liter to cost per gallon:

€1.726 Euro / 1 liter * $1 U.S. / €0.884 Euro * 0.26 gallons / 1 liter = $8.12 U.S. per gallon

Therefore, the cost of gas in Italy is about $8.12 U.S. per gallon.

What is Function?

The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

A. Since x-intercepts indicate the amount of each bacteria at the start of the experiment, there was more of bacteria B than bacteria A at the start.

False, it is the y-intercept of the function that indicates the amount at the start of the experiment.

B. Since y-intercepts indicate the amount of each bacteria at the start of the experiment, there was more of bacteria B than bacteria A at the start.

True, the y-intercept is given when x = 0, indicating the initial value of the function.

C. Since the maximum value in the table for bacteria A is greater than the maximum value in the table for bacteria B, bacteria A has a faster growth rate than bacteria B.

False, because the maximum value of each table is given in different times, and also the initial value of each table is different.

D. Since the minimum value in the table for bacteria A is less than the minimum value in the table for bacteria B, bacteria A has a slower growth rate than bacteria B.

False, the growth rate is not given by the initial value. If we model both tables with an exponential function, the count of bacteria A quadruped in two days, and the count of bacteria B doubled in one day, so they have the same growth rate.

The correct statement regarding the inverse function of f(x) = 4x^4 is given as follows:

\(f^{-1}(x) = \pm \left(\frac{x}{4}\right)^{\frac{1}{4}}\); f^(-1)(x) is not a function.

How to obtain the inverse function?

The function in this problem is defined as follows:

f(x) = 4x^4.

To obtain the inverse of a function y = f(x), first the variables y and x are exchanged, as follows:

x = 4y^4.

Isolating the variable y, we have that:

y^4 = (x/4).

The inverse operation of the fourth power is the fourth root, hence:

\(y = \pm \sqrt[4]{\frac{x}{4}}\)

\(f^{-1}(x) = \pm \sqrt[4]{\frac{x}{4}}\)

\(f^{-1}(x) = \pm \left(\frac{x}{4}\right)^{\frac{1}{4}}\)

The plus/minus symbol means that for each input of x, the inverse function gives two outputs, meaning that there are multiple outputs mapped to each input, and thus the inverse is not a function.

This means that the second statement is correct.

y = abˣ

Where,

Question 7.
The lifetimes of a certain brand of battery are assumed to be normally distributed with a mean of 405 hours.
Find the standard deviation of these battery lifetimes, if 90% of these batteries do not achieve a lifetime of 411
hours.
a) 0.2
b) 3.1
c) 3.7
d) 4.7

Answers

Answer: D

Step-by-step explanation:

To solve this problem, we need to use the standard normal distribution and the z-score formula.

First, we need to find the z-score that corresponds to the 90th percentile. We can use a standard normal distribution table or a calculator to find that the z-score is approximately 1.28.

Next, we can use the formula for the z-score:

z = (x - μ) / σ

where x is the value of interest, μ is the mean, and σ is the standard deviation.

We know that x = 411, μ = 405, and z = 1.28. We can rearrange the formula to solve for σ:

σ = (x - μ) / z

Plugging in the values, we get:

σ = (411 - 405) / 1.28

σ = 4.69

Rounding to one decimal place, we get:

σ ≈ 4.7

Therefore, the standard deviation of the battery lifetimes is approximately 4.7 hours, which is option (d).
