No.

The square root of any number can never be negative/ -1

The equivalent expression for [tex](3.7)^{-5}*(3.7)^{9}[/tex] is [tex](3.7)^{4}[/tex].

This is a question of exponents and powers.

Exponents

The exponent of a number says how many times to use the number in a multiplication. In [tex]8^2[/tex] the "2" says to use 8 twice in a multiplication, so [tex]8^2[/tex] = 8 × 8 = 64.

Here, 2 is the exponent or power and 8 is the argument.

We can use exponents when we have to deal with very large numbers.

For example:-

The distance between the Earth and the Sun is measured to be 149,600,000 Km.

To write it in simple terms we will write,

[tex]1.496 * 10^8[/tex] km.

We know that:-

[tex]a^b*a^c=a^{b+c}[/tex]

Here,

a = 3.7,

b = -5 and,

c = 9

Hence, we can write,

[tex](3.7)^{-5}*(3.7)^{9}=(3.7)^{-5+9}=(3.7)^{4}[/tex].

Answer: The decrease in price is $64, and the sale price is $192.

Step-by-step explanation:

0.25 * $256 = $64

$256 - $64 = $192

Step-by-step explanation:

the approach of the other answer is basically correct, but we need to use the correct numbers.

so, I assume that the 33% of the first solution is correct, and not the 23% mentioned later.

x = liters of the 33% solution.

y = liters of the 17% solution.

we know that

x + y = 1.8

and therefore

x = 1.8 - y

and then we want to enforce the desired result (ab% are simply 0.ab)

0.33x + 0.17y = 0.22×1.8

we use the identity from above in this equation :

0.33(1.8 - y) + 0.17y = 0.396

0.594 - 0.33y + 0.17y = 0.396

0.198 - 0.16y = 0

0.198 = 0.16y

y = 1.2375 liters

x = 1.8 - y = 1.8 - 1.2375 = 0.5625 liters

if the first solution is truly only 23%, then we only need to change the number :

0.23(1.8 - y) + 0.17y = 0.396

0.414 - 0.23y + 0.17y = 0.396

0.018 - 0.06y = 0

0.018 = 0.06y

y = 0.3 liters

x = 1.8 - y = 1.8 - 0.3 = 1.5 liters

Both methods are observational studies because both include students who do and do not play a musical instrument. So, this method describes an observational study.

Several various kinds of non-experimental studies in which behavior is routinely observed and documented are together referred to as observational research. A variable or combination of variables must be described in order to be the focus of observational research.

In a broader sense, the objective is to capture a moment in time of certain traits of a person, group, or environment. We cannot draw causal inferences from observational research since nothing is altered or controlled, as previously said, making it non-experimental. Although they may also be quantitative or both, the data that are gathered in observational research investigations are frequently qualitative in nature (mixed-methods).

Answer:

IF ITS THIS QUESTION

An article in a psychology journal claims that young students who play a musical instrument tend to have higher test scores on state math exams. To assess the claim, a government official considers two methods to collect data.

Method 1: Contact many city schools and ask them to provide summary data on state math exam performance and students who participate in music lessons.

Method 2: Choose two city schools and provide free music lessons to students who register. At the end of the year, compare state math exam scores for students who participated in the music lessons with the scores for those who did not.

Step-by-step explanation:

THE AWNSER IS C

Method 2 is an observational study because students can choose to participate in the music lessons.

An observational study is a type of research in which researchers observe and record the behavior of a group of individuals, but do not manipulate or intervene in any way. In this case, Method 2 describes an observational study because the researchers are not manipulating the students' participation in music lessons. Instead, the students are free to choose whether or not to participate in the music lessons, and the researchers simply observe and record the state math exam scores for both groups of students. In contrast, Method 1 is not an observational study because it involves collecting summary data on state math exam performance and music lesson participation, rather than observing and recording the behavior of the students.

The missing numbers in the third level can be 10, 6 and 18

On the first level of the number tower, we have

First level = 40

On the second level, we have

Second level = 16 and 24

The numbers on the third level of the number tower are missing.

However, these numbers must add up to the sum of 16, while the other must add up to 24

So, we can make use of

10, 6 and 18

This is because

10 + 6 + 6 + 18 = 40

Here, we have

2x + y = 14 and x + 2y = 16

Multiply 2x + y = 14 by 2

4x + 2y = 28

Subtract x + 2y = 16 from 4x + 2y = 28

4x - x + 2y - 2y = 28 - 16

Evaluate

3x = 12

Divide

x = 4

Also, we have 2x + y = 14

This gives

y = 14 - 2x

y = 14 - 2 x 4

y = 6

So, the values of x and y for 2x + y = 14 and x + 2y = 16 are 4 and 6, respectively

This has the same step as part (b)

In (b), we have

x = 4

Which gives

2x + y = 14

Make y the subject

y = 14 - 2x

Substitute 4 for x

y = 14 - 2 x 4

Evaluate

y = 6

Hence, the values of x and y for 2x + y = 14 and x + 2y = 16 are 4 and 6, respectively

Using an exponential function, it is found that:

An exponential function is modeled according to the following rule:

[tex]y = ab^{\frac{x}{n}}[/tex]

In which:

Considering that the pool has 1500 gallons, and drains 3% every 5 minutes, the parameters of the function are given as follows:

a = 1500, b = 1 - 0.03 = 0.97, n = 5.

Hence the amount of water in the poll after x minutes is given by:

[tex]y = 1500(0.97)^{\frac{x}{5}}[/tex]

After 50 minutes, the amount of water in the pool is:

[tex]y = 1500(0.97)^{\frac{50}{5}} = 1500(0.97)^{10} = 1106[/tex]

1106 gallons.

The poll will have less than 1000 gallons when:

y = 1000 (we can use it because the function decreases continuously).

Hence:

[tex]1500(0.97)^{\frac{x}{5}} = 1000[/tex]

[tex](0.97)^{\frac{x}{5}} = \frac{1000}{1500}[/tex]

[tex](0.97)^{\frac{x}{5}} = \frac{2}{3}[/tex]

[tex]\log{(0.97)^{\frac{x}{5}}} = \log{\left(\frac{2}{3}\right)}[/tex]

[tex]\frac{x}{5}\log{0.97} = \log{\left(\frac{2}{3}\right)}[/tex]

[tex]x = 5\frac{\log{\left(\frac{2}{3}\right)}}{\log{(0.97)}}[/tex]

x = 66.6 minutes.

The capacity of the pool is missing, and it is of 1500 gallons.

Symmetric property of congruence

The measure of ∡KJR is 69°.

What is the sum of two supplementary angles?
Two angles are referred to as supplementary angles if their combined value is 180°. A straight angle is created when supplementary angles are combined (180°).
In other words, ∡A and ∡B are supplementary if ∡A plus ∡B equals 180°. Angles A and B are described as "supplements" of one another in this context.
In math, A° + B° = 180°.

Given, m∡RJI = 12x - 3, m∡KJR = 6x - 5, m∡KJI = 172°
As seen from diagram, m∡RJI + m∡KJR = m∡KJI
⇒ (12x-3)+(6x-50) = 172° ⇒ 18x - 53 = 172° ⇒ x = ([172 + 53]/18)° = 12.5°
Therefore, the value of x = 12.5°
Thus, m∡KJR = 6x - 5 = (6*12.5) - 5 = 69°

The Inverse Function Line Test

A given graph represents a function only if for every value of x there is only one corresponding value of y.

This can be checked by using a vertical line and moving it through the x-axis. If that line intersects the graph more than once, then the graph does not correspond to a function.

The image shows a graph and if we move our imaginary vertical line from x=-2 to x=7 that line would intersect the graph only once. This means that the graph corresponds to a function in the domain [-2,7].

For the inverse function to exist, the horizontal line test must be passed.

Imagine a horizontal line moving through the y-axis. It would intersect the graph only once from y=0 to y=6.

We can conclude this graph corresponds to a function and it has an inverse function because it passed the horizontal line test.

The length of the sides of equilateral triangles are as follows

5cm,  15m , 8cm , 300m , 12m , 90mm .  

The whole length of a shape's boundary is referred to in geometry as the perimeter of the shape. By multiplying the lengths of all the sides and edges that surround an object, the perimeter may be calculated. It is measured in measures of length that are linear, such as centimeters, meters, inches, or feet. A regular polygon's sides are all the same length, as far as we know.

Therefore,

A regular polygon's perimeter is equal to the product of all of its sides, which is equal to the number of sides divided by the length of a side.

The measurement of a shape's length along its outline is known as its perimeter. Simple addition of the lengths of the object's edges serves as the perimeter measurement method.

The perimeter of an equilateral triangle

So,

(a) P = 15 cm

3a = 15

(b) 45 m

3a = 45

a = 15 m

each side = 15 m

(c) 24 m

each side =  8 cm

(d) 900 m

3a = 900

a = 300 m
