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]

Now separating the solutions we get

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

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

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

=> [tex]10^{log_{10}x} = 10^{-0.6021}[/tex]

=> x = 0.2499

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

From the graph of a function over the interval [-4,4]. the following are found for each function

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.

The negative part is the point -4.

Hence we can say that the domain is -4 ≤ x ≤ 4 with the positive and negative at 4 and -4 respectively

If (x+1) is a factor p(x)= x² + x + 2 then the value of x is -1.

An expression of one or more algebraic terms each of which consists of a constant multiplied by one or more variables raised to a nonnegative integral power

We have,

(x + 1) is a factor of p(x) = x² + x + 2

We need to find x.

Since (x + 1) is a factor of p(x) it should satisfy p(x).

x + 1 = 0

x = -1

Thus if (x+1) is a factor p(x)= x² + x + 2 then the value of x is -1.

According to the solving the line segment LM of line KM = 3.

A line segment is defined as the area between two different points on a line. A line segment is a section of a line that links two points. A line has no endpoints and stretches in both directions indefinitely, but a line segment includes two fixed or definite endpoints.

In general, if both end points of a line segment are vertices of such a polygon or polyhedron, the line segment has to be either the edge (of that polygon or polyhedron) if they are both adjacent vertices, or a diagonal. A chord is a line segment whose end points are both on a curve (such as a circle) (of that curve).

KL = 9

LM = x - 1

KM = -4 + 4x

So

KL + LM = KM

Substituting the value we get:

9 + x - 1 =  -4 + 4x

8 + x = -4 + 4x

8 + 4 = 4x - x

12 = 3x

x = 4

The value of x  = 4 putting the value in the (LM = x - 1):

We get:

LM = x - 1

LM = 4 - 1

     = 3

LM = 3

According to the solving the line segment LM of line KM = 3.

Answer:

38

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

The interest that 2560 earns in 17 months at a rate of 5 1/8% is $185.9.

In the fields of finance and economics, interest is the payment of a sum over and above the principal amount to a lender or depositor by a borrower or deposit-taking financial institution at a set rate. It is not the same as a fee that the borrower might pay to the lender or another entity.

Principal = $2560

Time = 17 months = 1.417 years

Rate = 5.125%

Therefore, the Interest will be:

= (Principal × Rate × Time) / 100

= (2560 × 1.417 × 5.125) / 100

= $185.9

Therefore, the interest that 2560 earns in 17 months at a rate of 5 1/8% is $185.9.

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

The simplest form of expression is (-32y¹⁵)^¹/₅ is -2y^3.
