\((\sqrt{2} )^3=\sqrt{2}. \sqrt{2}. \sqrt{2}\)

It gives in the approximate value is : 2.80

Surds are the square roots (√) of numbers that cannot be simplified into a whole or rational number. It cannot be accurately represented in a fraction. In other words, a surd is a root of the whole number that has an irrational value. Consider an example, √2 ≈ 1.414213. It is more accurate if we leave it as a surd √2.

We have from the question is:

Write in the surd form:

=> \(2^\frac{3}{2}\)

Now, According to the definition:

Write like this:

\(2^\frac{3}{2}=((\sqrt{2} )^2)^\frac{3}{2}\)

Cancel out the:

2 × 3/2 = 3

So, \((\sqrt{2} )^3=\sqrt{2}. \sqrt{2}. \sqrt{2}\)

It gives in the approximate value is : 2.80

a) The scale factor from shape A to B is 4/3.

b) Using the scale factor, the value for w is obtained as 5.25.

What is scale factor?

The scale factor of a shape refers to the amount by which it is increased or shrunk. It is applied when a 2D shape, such as a circle, triangle, square, or rectangle, needs to be made larger.

The diagram have two quadrilaterals which are similar.

To find the scale factor apply the proportion formula -

A : B = 4 : 3

So, the scale factor is -

A/B = 4/3

Therefore, the scale factor value is 4/3.

To find the value for length w use the scale factor.

The proportion expression is -

A : B = 7 : w

Substitute the values into the equation -

4 : 3 = 7 : w

Solve to get the value for w.

4/3 = 7/w

4w = 21

w = 21/4

w = 5.25

Therefore, the value for w is obtained as 5.25.

Answer: > if the other number is 20

Step-by-step explanation:

It would take approximately 48.12 days for the radioactive iodide taken up and held by the thyroid to decay to 0.01% of the original amount.

To determine the time it takes for the radioactive iodide taken up by the thyroid to decay to 0.01% of the original amount, we can use the concept of radioactive decay and the half-life of iodine-131.

Half-life of iodine-131: 8.02 days

Fraction of iodide taken up by a normal thyroid: 12%

Fraction remaining after decay: 0.01% (or 0.0001) of the original amount

Let's assume we start with 100 units of radioactive iodide taken up by the thyroid. After the first half-life (8.02 days), half of the iodide will decay, so we'll have 50 units remaining. Since a normal thyroid takes up 12%, we multiply the remaining units by 0.12 to find the amount taken up: 50 units × 0.12 = 6 units.

Now, we have 6 units remaining in the thyroid, and we'll repeat the process for subsequent half-lives until we reach 0.01% of the original amount.

1st half-life: 50 units remaining (0.12 taken up)

2nd half-life: 25 units remaining (0.12 taken up)

3rd half-life: 12.5 units remaining (0.12 taken up)

4th half-life: 6.25 units remaining (0.12 taken up)

5th half-life: 3.125 units remaining (0.12 taken up)

6th half-life: 1.5625 units remaining (0.12 taken up)

After 6 half-lives, the remaining iodide in the thyroid is approximately 1.5625 units, which is 0.015625% of the original amount (100 units).

To calculate the time it takes for the radioactive iodide taken up by the thyroid to decay to 0.01% of the original amount, we need to multiply the half-life by the number of half-lives

Time = Half-life × Number of half-lives

= 8.02 days × 6

= 48.12 days

Answer:

A. 6 chaperones

Step-by-step explanation:

Since it's 2 chaperones per 25 students you would need to see how many times 25 can fit into 82

82/25 = 3.28

You can round that number to 3

Then you'll multiply 3 by 2 to get your number of chaperones for the school trip

3 x 2 = 6

There's still students left but not enough for there to be another chaperone so the answer is 6

The statement that , "The set Span{u,v} is always visualized as a plane through the origin" is False because if vectors are scalar multiples of each other, then set Span{u,v} is a line through origin .

The set Span{u,v} is defined as the set of all linear combinations of vectors "u" and "v" . This set can be visualized as a plane in three-dimensional space if the vectors are not scalar multiples of each other.

The plane may not necessarily pass through the origin, unless one of the vectors is the zero vector .

The total amount accumulated after 4 years of $2,000 at 4% Interest (compounded annually) is approximately $2,169.86.

The total amount accumulated after 4 years of $2,000 at 4% interest, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the final amount

P = the principal amount (initial investment)

r = the annual interest rate (expressed as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, the principal amount (P) is $2,000, the annual interest rate (r) is 4% or 0.04 (expressed as a decimal), the number of times the interest is compounded per year (n) is not specified, and the number of years (t) is 4.

Let's assume that the interest is compounded annually (n = 1). Plugging the values into the formula, we have:

A = $2,000(1 + 0.04/1)^(1*4)

A = $2,000(1 + 0.04)^4

A = $2,000(1.04)^4

A ≈ $2,169.86

Therefore, the total amount accumulated after 4 years of $2,000 at 4% interest (compounded annually) is approximately $2,169.86.

Answer:

5.12 in. by 7.68 in.

Step-by-step explanation:

In similar triangles, the ratios of the lengths of corresponding sides are equal.

width of medium triangle = 4/5 width of large triangle

width of medium triangle = 4/5(8 in.) = 6.4 in.

length of medium triangle = 4/5 length of large triangle

length of medium triangle = 4/5(12 in.) = 9.6 in.

width of small triangle = 4/5 width of medium triangle

width of small triangle = 4/5(6.4 in.) = 5.12 in.

length of small triangle = 4/5 length of medium triangle

length of small triangle = 4/5(9.6 in.) = 7.68 in.

The probability that the sample mean would be greater than 148.6 millimeters is 0.017

The spread of all the data points in a data collection is taken into account by the variance, which is a measure of dispersion.

Given  Population mean μ= 147

Population Variance σ^2 = 25

So, population SD = 5

Size of sample = n = 44 Sample mean = x

To find P( y > 148.6) :

SE =σ/√n =

5/√44= 0.7538

Transforming to Standard Normal Variate:

Z = (x - μ )/SE    

= (148.6 - 147)/0.7538    

= 2.1226

From Table of Area Under Standard Normal Curve, corresponding to Z = 2.1226, area = 0.4830.

So, required probability = 0.5 - 0.4830 = 0.017

The probability of getting at least one nun in three spins of a dreidel is approximately 0.578

The probability is the ratio of number of favorable outcomes to the total number of outcomes

The probability of getting no nuns in a single spin is 3/4, since there are three non-nun letters (Gimel, Hei, Shin) and four total letters.

The probability of getting no nuns in three spins is then (3/4)^3, since the spins are independent and we can multiply probabilities of independent events.

So the probability of getting at least one nun in three spins is

= 1 - (3/4)^3

= 1 - 0.421875

= 0.578125

Therefore, the probability of getting at least one nun is 0.578

A. Without computing, the sum of 2, 3, and -2 is 3.

B. The explanation that supports the answer in Part A is (A) 2 and -2 are additive inverses and the sum of any number and its additive inverse is zero. The integer 3 is positive, so the sum with be positive.

An additive inverse of a number is the value that results in zero when added to the original number. It is the value that we add to a number in order to get zero. If an is the original number, then its additive inverse is minus a, i.e., -a, such that;

a+(-a) = a – a = 0

By changing the sign of a number, we can find its additive inverse. A positive number's additive inverse is negative, while a negative number's additive inverse is positive. Except for the sign, the numerical value will not change. The additive inverse of 8 is -8, for example, while the additive inverse of -6 is 6.

Step-by-step explanation:

To solve this question we must use Pythagoras (a²+b²=c²) Let those two dots be A and B respectively.Imagine a line is drawn that pases through both dots,

Imagine that the line given is the hypotenuse (the longest side of a right-angled triangle) of a right-angled triangle and the other sides as a line from A going to the right, and a line from B going downwards, making the final vertexes for the triangle at coordinates: 0,-5  4,1 and 4,-5 (the vertex we made). now we find the lengths for the sides: 4 and 6 so we use these to plug them into pythagoras's equation:

4²+6²=c²

24+36=c²

√60=c

c=7.74....

Answer:

4y = 6x + 40

Step-by-step explanation:

The general equation of a straight line is y = mx + b

m is the slope and b is the y-intercept

let us write both equations in this form;

we have this as;

6y = -4x + 1

y = -4x/6 + 1/6

and;

2x + 3y = 18

3y = -2x + 18

y = -2x/3 + 6

So firstly we want to find an equation that is perpendicular to the first

When two lines are perpendicular, their slopes has a product of -1

The slope of the first line is -4/6

let the slope of the line we want be m

As per they are perpendicular;

-4/6 * m = -1

-4m/6 = -1

-4m = -6

m = 6/4

So now, we want the y-intercept greater than that of the second equation which is a y-intercept of 6

we can choose 10

and we have the equation as:

y = 6x/4 + 10

multiply through by 4

4y = 6x + 40
