It should be noted that 5 groups of 2 hundredths will be 3.2e-9.

It should be noted that the information is simply about finding 5 groups of 2 hundredths.

In this case, this will be illustrated as:

= 5 × 2 hundredths

It should be noted that 2 hundredths simply means 0.02. Therefore, the information is to calculate 0.02 in 5 places. This will be illustrated thus:

= 0.02 × 0.02 × 0.02 × 0.02 × 0.02

= 3.2e-9.

Therefore, it should be noted that 5 groups of 2 hundredths will be 3.2e-9.

The linear function slope, f(2)=-4, and f(3)=2 the equation for f(x) is y = 6x +6

This is the same as finding the line that goes through the two points (3,2) and (2,-4)

It has slope[tex]\frac{-6}{-1}[/tex] = 6 = [tex]\frac{(-4-2)}{(2-3)}[/tex] = m=6.  slope = rise/run.  or change in y coordinates/change in x coordinates

The y-intercept is given by(2,-4) as 6, b= 6. so plug that into the slope-intercept equation

y= MX + b

y = 6x +6

It's just a coincidence they both happened to = 6. m=b=6

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.  the web change in the y-coordinate is represented by Δy and the net change in the x-coordinate is represented by Δx. Where “m”  is the slope of a line. So, tan θ to be the slope of a line.

Pick two points on the road and determine their coordinates. Determine the difference in y-coordinates of those two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

Whenever the equation of a line is written within the form y = MX + b,  it's called the slope-intercept form of the equation. The m  is the slope of the line. And b  is that the b in the point that is the y-intercept (0, b).  for instance, for the equation y = 3x – 7, the slope is 3,  and therefore the y-intercept is (0, −7).

The solutions to the equation (3x - 5)²= 19 are: - [tex]\frac{\sqrt{19} + 5}{3}[/tex] and [tex]\frac{\sqrt{19} + 5}{3}[/tex] .

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign.

In this question we have been given an equation that is (3x - 5)²= 19

Now taking square root both sides

(3x - 5)² = 19

3x - 5 = ± [tex]\sqrt{19}[/tex]

Add 5 to both sides to make equation simpler

3x = ± [tex]\sqrt{19}[/tex]+ 5

Divide both sides by 3

x = ±[tex]\frac{\sqrt{19} + 5}{3}[/tex]

The components of -5RS are {-20; 65}.

The components of a vector in a two-dimensional coordinate system are usually thought of as the x and y components. This can be expressed as V = (vx, vy). where V is a vector. These are part of the vectors generated along the axis.

Suppose an angle θ is formed between the vector V and the x component of the vector. A vector V and its x component (vx) form a right triangle if you draw a line parallel to the y component (vy).

Due to the trigonometric relationship

cos θ = adjacent side/hypotenuse = vx/V

sin θ = opposite side/hypotenuse = vy/V

where V is the magnitude of vector V.

So, the Component of -5RS is Given by:

-5RS = -5* {Sx - Rx; Sy - Ry} = {2 - (-2); -8 - 5} = -5*{4; -13}

-5RS = {-20; 65}

The domain of a function refers to the input variables, often times the domain comprises of the x axis. for the given graph the domain is -4 ≤ x ≤ 4.

This would be through the points in the function. We are given  [-4,4]

-4 is the negative side while 4 is the positive. We have to write this out as

-4 ≤ x ≤ 4.

The positive part part of the function is at 4. This is because we can assume a +4 sign.

Answer:

Step-by-step explanation:

It is clear that the number of sweets that should be bought so that each child can get either 8 or 9 sweets should be divisible by both 8 and 9

This is called the LCM or least common multiple of 8 and 9
Since 8 and 9 have no divisors in common LCM of 8 and 9 is 72 so 72 is the minimum number of sweets to buy so that there are no leftovers if each child gets 8 or 9 sweets

Let's compute the number of sweets that were bought the first time. Let the number of children be X

Since each child got 8 sweets and 2 were left over, the total of sweets must be 8X + 2

If each child were to get 9 sweets each then there would be 2 sweets short

This can be written as 9X -2 for the total number of sweets

Since these have to be equal,
9X - 2 = 8X + 2

Add 2 to both sides:
9X - 2 + 2 = 8X +2 + 2
9X = 8X + 4

Subtract 8X from both sides
9X - 8X = 8X - 8X + 4
1X = 4
==> X = 4
So number of children is 4

Total number of sweets bought
= 8 x 4 + 2 = 34

or

= 9 x 4 - 2 = 34

Therefore number of extra sweets to be bought = 72 - 34 = 38

By  -236 dB approximately the noise is reduced on imparting sound barrier.

Given that, the foreman of a construction team puts up a sound barrier that reduces the intensity of the noise by 50%. Let the intensity of the sound is I and it is reduced 50% then, new intensity of sound will be

new intensity after reduction = I-50% of I = I/2

Now, the Loudness is calculated by using the formula,

L = 10 log I/I₀

now, I = I/2 and I₀ = 10⁻¹² W/m²

So, we have to find out by how many decibels(dB) the noise is reduced after putting a sound barrier.

This will simply be calculated by subtracting the two noise before and after the sound barrier indulgence. Let's proceed to solve accordingly.

L = 10 log I/I₀ - 10 log I/2I₀

= 10(log I/I₀ - log I/2I₀)

By using the logarithmic property, log(a/b) = log a - log b

= 10(log I-log I₀-log I-log2I₀)

= 10(-log I₀ - log2I₀)

= -10(log I₀ + log2I₀)

Now, we know that, I₀ = 10⁻¹² W/m²

Put the value of I₀ and solve accordingly, we get

L = -236 dB approximately

log (5) - log (2x) = 1 => x = 0.2499, by properties of logarithm.

Now,

log(5) - (log (2x)) =1

=> log (5) - [log (2) + log (x)] = 1 (as log(ab) = log(a) + log (b))

=>log (5) - log (2) - log (x) = 1

=> log ([tex]\frac{5}{2}[/tex]) - log (x) = 1

=> 0.3979 - log (x) = 1

=> log (x) = 0.3979 - 1

Since, generally the base of log is 10, raising them to 10

The simplest form of the expression is determined by solving the fractional exponent.

If an exponent of the base (number) is expressed in a fraction, it is called a fractional exponent. In an expression say x^1/y, 1/y is the fractional exponent. Fractional exponent represents the power and root together.

In the given expression, the base term is -32y^15, while the exponent is 1/5.

Since, (ab)^m=a^mb^m

Hence, (-32y¹⁵)^¹/₅=(-32)^1/5*(y^15)^1/5

When a base number has a negative sign, and the power is an odd number, the negative sign is extracted.

(-32)^1/5*(y^15)^1/5=-(32)^1/5*(y^15)^1/5

Since, (a^m)^n=a^m*n

-(32)^1/5*(y^15)^1/5=-32^1/5y^15*1/5

As 32=2*2*2*2*2=2^5

The expression becomes.

-(2^5)^1/5*(y^15^)1/5

Multiplying the powers,

-(25)^1/5*(y^15)^1/5=-(2^5*1/5)(y^15*1/5)=-2y^3
