The expression 16t-3t is not equivalent to 3t-16t because the negative sign belongs to the term 3t

For t = 2, 16t - 3t is equal to 26 and 3t - 16t is equal to -26

We know that an expression is nothing but a mathematical sentence with a minimum of two numbers or variables and at least one algebraic operation.

Also,  if two expressions are equivalent expression , then the two expressions must have the same value when we substitute the same values for the variables.

Here we have been given two mathemtical expressions:

16t - 3t and 3t - 16t

For t = 2,

16(2) - 3(2)

= 32 - 6

= 26

and 3(2) - 16(2)

= 6 - 32

= -26

This means, 16t - 3t ≠ 3t - 16t

We can oberve that 16t - 3t = -(-16 + 3t)

= -(3t - 16)

This means, 16t-3t is not equivalent to 3t-16t because the negative sign belongs to the term 3t

The radical expression completely:

Square root of [tex]48x^2y^5z[/tex] is  4[tex]xy^2[/tex] × sqrt(3y)

Now, According to the question:

Factor 48 into its prime factors

          48 = 24 × 3

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :

          16 = [tex]2^4[/tex]

Factors which will remain inside the root are :

          3 = 3

To complete this part of the simplification we take the square root of the factors which are to be extracted. We do this by dividing their exponents by 2 :

          4 = [tex]2^2[/tex]

At the end of this step the partly simplified SQRT looks like this:

        4 × sqrt[tex](3x^2y^5)[/tex]z

Rules for simplifying variables which may be raised to a power:

  (1) variables with no exponent stay inside the radical

  (2) variables raised to power 1 or (-1) stay inside the radical

  (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

    (3.1) sqrt[tex](x^8)=x^4[/tex]

    (3.2) sqrt(x-6)=x-3

(4) variables raised to an odd exponent which is  >2  or < (-2) , examples:

     (4.1)[tex]sqrt(x^5)=x^2sqrt(x)[/tex]

    (4.2) sqrt(x-7)=x-3sqrt(x-1)

Applying these rules to our case we find out that

    SQRT[tex](x^2y^5) = xy^2[/tex]SQRT(y)

Simplified root:

4[tex]xy^2[/tex] × sqrt(3y)

Hence, the radical expression completely:

Answer:

2c + 12 = 20. Simplified to 2c = 8

Step-by-step explanation:

We can start with a Template

Y = Xc + C

Y being the total

X being candy price

c bring candy boxes, as stated

C being ticket price

Plugging those in we get

20 = 2c + 12

Since you bought the ticket with your $20, we can subtract the ticket price from both sides, giving you

8 = 2c or 2c = 8

The required function is 200 (1.4)ˣ = 5, where the value of x is calculated to be -11.

The given function is y = a bˣ

x₁ = 0, y₁ = 200

x₂ = 2,  y₂ = 392

Let us determine a, b.

a b⁰ = 200

a b² = 392

a = 200

200 b² = 392

b² = 392/200 = 49/25 = 7/5 = 1.4

So, the function is y = 200 (1.4)ˣ

Now, let us determine x for y = 5,

200 (1.4)ˣ = 5

(1.4)ˣ = 0.25

Taking log on both sides,

log (1.4)ˣ = log 0.025

x log 1.4 = log 0.025

x = log 0.025/log 1.4

x ≈ -11

The first diagram is the equation represented by 5 . 2 = 10 and the second diagram is the one with the equation represented by 2 + 5 = 7.

Tape diagrams are diagrams which are used to understand about the relationship between quantities and also they describe how those relationships has been described by operations.

Given are two tape diagrams.

First take the equation 2 + 5 = 7.

This means that 2 is just added to 5 to get 7.

One part contains 2 and the other part contains 5.

Length of it is 7.

Consider the second equation 5 × 2 = 10.

5 × 2 actually means that 5 is added to itself two times or 2 is added to itself five times.

Either 5 + 5 = 10 or 2 + 2 + 2 + 2 + 2 = 10

We have a diagram with 5 equal parts of 2.

Length is 10.

Hence the length of the first diagram is 10 and the length of second diagram is 7.

ax² + bx + c = 0

Discriminant 'D' = b² - 4ac

option a. -x²+ 18x + 81

Discriminant

'D' = 18² - 4(-1)(81)

      = 648

D>0 has distinct roots.

option b. 3x²- 3x - 168

Discriminant

'D' = (-3)² - 4(-3)(-168)

      = -2007

D< 0 has distinct roots.

option c. x²- 4x -  4

Discriminant

'D' = (-4)² - 4(1)(-4)

      = 16 + 16

      = 32

D>0 has distinct roots.

option d. 25x²- 30x + 9

Discriminant

'D' = (-30)² - 4(25)(9)

The probability of drawing a white chip first and a blue chip second is 1/5.

To find the probability of drawing a white chip first and a blue chip second, we can use the formula for conditional probability.

Conditional probability is the probability of an event occurring given that another event has already occurred. It is represented by the notation P(A|B), where A is the event of interest and B is the event that has already occurred.

The formula for conditional probability is:

P(A|B) = P(A and B) / P(B)

This formula expresses the probability of event A occurring given that event B has occurred, as a ratio of the probability of the two events occurring together and the probability of event B occurring alone.

Where A is the event of drawing a white chip first and B is the event of drawing a blue chip second.

We know that the probability of drawing a white chip first is 3/10 (since there are 3 white chips out of a total of 10 chips in the bowl), so P(A) = 3/10.

Once a white chip has been drawn, there are 9 chips left in the bowl, with 6 of them being blue. This means that the probability of drawing a blue chip second given that a white chip has already been drawn is 6/9, so P(B|A) = 6/9.

By multiplying these two probabilities together, we get:

P(A and B) = (3/10) * (6/9) = (3/10) * (2/3) = 6/30 = 1/5

Therefore, the probability of drawing a white chip first and a blue chip second is 1/5.

Book 2 with 4 kg weight has the higher gravitational pull and the  pull decreases with increase in distance.

In Physics, the gravitational force is one of the types of forces. It is a force that attracts any two objects with mass. The gravitational force is also known as the attractive force, as it always pulls the masses of two objects together. Newton’s gravitational law states that every object in the universe is pulled by other objects. The other types of forces are electromagnetic force, strong force, weak force, and so on. The formula to calculate the gravitational force is given by Gravitational Force = (Gravitational Constant × Mass of first object × Mass of the second object) / (Distance between the centre of two bodies)².

Given here:

Book 1 has 2 kg textbook and Book 2 weighs 4 kg.

In the first case The gravitational pull when they were 2 cm apart is

F₁=    Gm₁m₂  / 2cm

  =0.00000133486 N

While if the two books are 8 cm apart we have

F₂= Gm₁m₂  / 8

  =0.0000000834288 N

clearly the gravitational pull decreases with the increase in distance.

And owing to Book 2's higher weight it has the superior gravitational pull.

Hence, Book 2 with 4 kg weight has the higher gravitational pull and the  pull decreases with increase in distance.
