Answer:

Option 3 - [tex]2.04\times 10^4[/tex]

Step-by-step explanation:

Given : Numbers [tex]7.2\times 10^{-6}[/tex] , [tex]3.09\times 10^3[/tex][tex]2.04\times 10^4[/tex] and [tex]5\times 10^3[/tex]

To find : Which number is largest ?

Solution :

We solve all number in standard form,

1) [tex]7.2\times 10^{-6}=\frac{72}{10}\times \frac{1}{1000000}[/tex]

[tex]7.2\times 10^{-6}=0.0000072[/tex]

2) [tex]3.09\times 10^3=\frac{309}{100}\times 1000[/tex]

[tex]3.09\times 10^3=3090[/tex]

3) [tex]2.04\times 10^4=\frac{204}{100}\times 10000[/tex]

[tex]2.04\times 10^4=20400[/tex]

4) [tex]5\times 10^3=5\times 1000[/tex]

[tex]5\times 10^3=5000[/tex]

The decimal number is the least number among all.

The five digit number is the greatest number among all.

So, 20400 is the greatest number.

Which means [tex]2.04\times 10^4[/tex] is the largest number.

Therefore, Option 3 is correct.

Answer:

(A) 5.5 units

Step-by-step explanation:

Given: Diameter AC intersects chord BD at point E such that AE = 2.5 units and DE = 3.4 units. Point O is the center of the circle, and the radius of the circle is 5 units. we have to find the approximate length of BE.

Now, CE=CO+OE=5+(OA-AE)=5+2.5=7.5 units.

Now, by Intersecting Chord Theorem which states that when two chords intersect each other inside a circle then the products of their segments are equal.

Thus, [tex]CE{\times}AE=BE{\times}DE[/tex]

Substituting the given values, we get

[tex]7.5{\times}2.5=3.4{\times}DE[/tex]

[tex]\frac{7.5{\times}2.5}{3.4}=DE[/tex]

[tex]5.541=DE[/tex]

[tex]DE[/tex]≈[tex]5.5{\text{units}[/tex]

therefore, the measure of DE is 5.5 units.

Hence, option A is correct.

Step-by-step explanation: I took the test on FLVS

To find the total number of students, set up a proportion and solve for x. The total number of students is 1640.

To find the total number of students, we can set up a proportion using the information given. If three-fourths of the student body attended the pep-rally, that means three-fourths of the total number of students is equal to 1230. Let's let x represent the total number of students. Then, we can write the proportion as:

3/4 = 1230/x

Now, to solve for x, we can cross multiply:

3x = 4 x 1230

Dividing both sides by 3:

x = 4 x 1230 / 3

Calculating the expression on the right side of the equation:

x = 4920 / 3

Finally, divide 4920 by 3 to get:

x = 1640

So, there are 1640 students in total.

The balance in your account after five years will be approximately $1,118.85.

Step 1: Understand Continuous Compounding

In continuous compounding, interest is earned not only on the initial principal amount but also on the accumulated interest over time. This means interest is calculated continuously throughout the year, leading to a slightly higher final balance compared to simple interest.

Step 2: Formula for Continuous Compounding

The formula for continuous compounding to find the future value (balance) after t years is:

A = P * e^(r*t)

where:

Step 3: Apply the Formula

Step 4: Calculate the Final Balance

You can use a calculator to evaluate the expression.

A ≈ $750 * e^(0.4) ≈ $750 * 1.4918

Step 5: Round the Answer (Optional)

Depending on the desired level of precision, you can round the answer to two decimal places:

A ≈ $1118.85 (rounded to two decimal places)

The probability that Aly won't purchase either car A or car B is 0.18. This is calculated by subtracting the combined probability of purchasing either car from 1.

The question pertains to the concept of probability, which can be defined as a measure of the likelihood that a given event will occur. In this case, Aly is deciding between two cars to purchase (Car A and Car B). The probability that she will purchase car A is 0.47 and the probability that she will purchase car B is 0.35. These probabilities might have been estimated based on Aly's preferences, past behavior, or other relevant factors.

Since probabilities add up to 1, we can calculate the probability that Aly won't purchase either car A or car B by subtracting the sum of the probabilities of buying car A and car B from 1. So, we do 1 - (0.47 + 0.35) = 0.18. Therefore, the probability that she will not purchase either car A or car B is 0.18.

If you look at the clock and it is exactly 2pm. you set an alarm to go off in 51 hours then 5PM is the time when alarm go off.

Time can be defined as an ongoing and continuous sequence of events that occur in succession, from past through the present, and to the future.

Given that You look at the clock and it is exactly 2pm and set an alarm to go off in 51 hours.

We need to find at which time the alarm go off.

We know that in a clock we will have 12 hours.

For every 12 hours the PM changes to PM.

2PM-2PM=24 hours

2PM-2PM=24 hours

When we add the hours we get 48 hours still we needed three more hours to turn off the alarm

2PM-5PM=3 hours.

at 5PM it becomes 51 hours.

We are given the functions:

S (p) = 40 + 0.008 p^3                                     ---> 1

D (p) = 200 – 0.16 p^2                                     ---> 2

T o find for the price in which the price of supply equals demand, all we have to do is to equate the two equations, equation 1 and 2, and calculate for the value of p, therefore:

S (p) = D (p)

40 + 0.008 p^3 = 200 – 0.16 p^2

0.008 p^3 + 0.16 p^2 = 160

p^3 + 20 p^2 = 20,000

p^3 + 20 p^2 – 20,000 = 0

Calculating for the roots using the calculator gives us:

p = 21.86, -20.93±21.84i

Since price cannot be imaginary therefore:

p = 21.86

Final answer:

To take the square root of a number, use the square root function on a calculator or raise the number to the power of 0.5. For higher roots, like fourth roots, raise to the power of 0.25, or take the square root twice. Adjust exponentials before taking roots and estimate if a calculator is not available.

Explanation:

To take the square root of a number, you can perform this operation either by using a calculator or through manual calculations. If you're using a calculator, simply use the square root function, which is usually represented by a radical sign (√) or sometimes as a button labeled 'sqrt'. However, when dealing with equations or expressions where the variable is raised to a power, such as , you will need to take the fourth root to solve for T. This is equivalent to raising the number to the 0.25 power (since 1/4 is equivalent to the fourth root). You can verify this method by checking that the square root of a number is the same as that number raised to the 0.5 power.

In case you are working with exponentials, remember to adjust the exponent so it's evenly divisible by 2 before extracting the square root. If the number is written in scientific notation, extract the square root of the coefficient and halve the exponent. For example, taking the square root of 1 x 104 would be 1 x 102 since the square root of 1 is 1 and half of 4 is 2.

When you lack a calculator, estimating roots, such as cube roots or higher, can be done with a rough mental approximation. For instance, to find the cube root of 87, you know that the cube root of 64 (which is 4) is too small and the cube root of 125 (which is 5) is too big, so you can start by guessing around 4.3. With trial, error, and adjustments, you can find a more accurate result.

Answer:

Abel is 3 years older than Zöe.

Step-by-step explanation:

Abel and Zöe’s grandparents opened a savings account for an equal amount upon the birth of each child. Now, the values of their accounts could be found by the following expressions, where t represents the years since 2011.

Abel: y = 1266.77(1.03)^t

Zöe: y = 1159.27(1.03)^t

To find the difference in children's ages first we take ratio of 1266.77/1159.26

Ratio of 1266.77/1159.26= 1.09

now we write ratio in terms of powers of 1.03

1.03^t = 1.09

Take ln on both sides

t ln(1.03) = ln(1.09)

Divide both sides by ln(1.03)

t= 3

Abel is 3 years older than Zöe.
