GIVEN :-

[tex]x = -\frac{1}{2}[/tex][tex]y = \frac{2}{4} = \frac{1}{2}[/tex][tex]z= -\frac{2}{8} = -\frac{1}{4}[/tex]

TO VERIFY :-

[tex]x + (y + z) = (x + y) + z[/tex]

SOLUTION :-

L.H.S. =

[tex]x+ (y + z)[/tex]

[tex]=> -\frac{1}{2} + (\frac{1}{2} + \frac{-1}{4} )[/tex]

[tex]=> -\frac{1}{2} + (\frac{2 - 1}{4} )[/tex]

[tex]=> -\frac{1}{2} + \frac{1}{4}[/tex]

[tex]=> \frac{-2 + 1}{4}[/tex]

[tex]=> -\frac{1}{4}[/tex]

R.H.S. =

[tex](-\frac{1}{2} + \frac{1}{2} ) + \frac{-1}{4}[/tex]

[tex]=> 0 - \frac{1}{4}[/tex]

[tex]=> -\frac{1}{4}[/tex]

∴ L.H.S. = R.H.S. (Verified)

The three side lengths of four triangles are given which triangle is a right triangle



Answers

Answer:

Triangle 3: 3, 4 ,5

Step-by-step explanation:

Well, you can easily tell by 3, 4, 5 being a Pythagorean triple.

But you have to use the Pythagorean Theorem to solve this.

So you get the side lengths of the two shortest sides, and you add the squared versions of them together.

So: 3^2+4^2 and if that equals the biggest side:5^2 then it's a right triangle.

Answers

Answer:

Even positive

Step-by-step explanation:

Given

[tex]f(x) = -2x^3 + x^4 + 1[/tex]

Required

The end behavior

We have:

[tex]f(x) = -2x^3 + x^4 + 1[/tex]

Rewrite as:

[tex]f(x) = x^4 -2x^3 + 1[/tex]

To describe the end behavior, we check the leading coefficient and the degree of the function.

We have:

Leading Coefficient = 1 (i.e. the coefficient of [tex]x^4[/tex])

Degree = 4 (i.e. the power of [tex]x^4[/tex])

The degree of the function is even (i.e. 4)

The leading coefficient is positive (i.e. 1)

Hence, the end behavior is Even positive

how to get a square root of a given number​

Answers

Answer:

Step-by-step explanation:

The square root of a number is defined as [tex]\pm y=\sqrt[2]{x}[/tex] where [tex](\pm y)^{2}[/tex] gives the original number. For example, [tex]\sqrt{4}=\pm2[/tex] because [tex]2^{2}=2*2=4[/tex] and [tex](-2)^{2}=-2*-2=4[/tex].

The square root of 9 is 3. The number 9 is an integer. This number comes from multiplying 3×3 which results in the number 9The square root of 25 is 5. The number 25 is an integer. This number comes from multiplying 5×5 which results in the number 25The square root of 81 is 9. The number 81 is an integer.

Mr. Blake took 10 minutes to drive 5 miles,
He claims it will take half an hour to drive 15 more miles at the same rate.

Select all the statements that are true if Mr. Blake claim is true.

1. He will travel 2 miles per minute.

2. Hw would travel 50 miles in 25 minutes.

3. He will travel 1 mile for every 2 minutes.

4. He will travel at a rate of 30 miles per hour.

5. The ratio of miles driven to minutes traveled is 1:2.

Answers

Answer:

The correct answer is - 3, 4, and 5.

Step-by-step explanation:

Given:

distance = 5 miles

time to cover 5 miles = 10 minutes

If his claim is true then,

additional Distance = 15 miles

total distance will be = 15+5 = 20 miles

additional time = 30 minutes

total time = 10+30 = 40 minutes

Solution:

The speed of the vehicle can be calculated by the formula:

V = d/t

where V is speed or velocity

d = distance

t = time

Putting the final or total values in formula =

V = 20/40

= 1/2 (5th statement is true)

In an hour where 60 minutes are there, 1/2 = 30 miles per hour.

Thus, 3rd and 4th statement are true.

Which statement best describe the diagonals of a rhombus?

B) Is a parallelogram with diagonals that bisects a pair of opposite angles and the diagonals are perpendicular

C) Is a parallelogram with the diagonals that intersect but does not form 90 degree

D) Is a parallelogram with diagonals that are congruent and perpendicular

Answers

Answer:

Is a parallelogram with congruent diag............ option is best describing better

The statement which best describes the diagonals of a rhombus is B. Is a parallelogram with diagonals that bisects a pair of opposite angles and the diagonals are perpendicular.

What is Rhombus?

A rhombus is a two dimensional shape which consists of four equal sides with opposite side being parallel and opposite angles being equal.

So, rhombus is a parallelogram with all sides being equal.

The diagonals of a rhombus are not of equal length, so they are not congruent.

Also, the two diagonals of a rhombus cuts each other in to two equal halves and the intersecting angle is 90 degrees.

This means that the diagonals of a rhombus are perpendicular bisectors of each other.

Also, the diagonals bisect the pair of opposite angles through which the line passes.

Hence the correct option is B. Is a parallelogram with diagonals that bisects a pair of opposite angles and the diagonals are perpendicular.

A. The number of stuffed animals in Denise’s collection is multiplied by 4 each year.
B. Denise’s collection increases by 4 stuffed animals per year.
C. Denise’s collection increases by 3 stuffed animals per year.
D. Denise spends $4 per year on stuffed animals.

Answers

The statement best describes the rate of change is "Denise's collection increases by 4  stuffed animals each year".

What is rate of change ?

The rate of change is the speed at which a variable changes over a specific period of time.

According to the given question

We have

An equation a(n) = 3+4n, which describes the number of stuffed animal in Denise collection, a after n, number of years.

For the rate of change

Differentiate the given equation w.r.t n

[tex]\frac{d(a(n))}{dn} =\frac{d}{dn} (3) + \frac{d}{dn} (4n)[/tex]

⇒[tex]\frac{d}{dn} a(n) = 0+ 4 =4[/tex]

⇒ the number of stuffed collection increases by 4 each year.

Hence, option B is correct.

Here’s the revenue and expenses for the month. Calculate whenever Mia had profit or loss.

Answers

Answer:

Profit = $200

Step-by-step explanation:

Total revenue = $9,500

Fixed expenses = $9,000

Variable expenses = $300

Total expenses = Fixed expenses + Variable expenses

= $9,000 + $300

= $9,300

Total expenses = $9,300

Profit is when revenue is greater than expenses

Loss is when revenue is less than expenses

Mia made profit because her revenue is more than her expenses

Profit = Revenue - Expenses

= $9,500 - $9,300

= $200

Profit = $200

Step-by-step explanation:

Let b = -1 and a = -3

The average rate of change = [tex]\frac{f(b) - f(a)}{b - a}[/tex]

f(b) = f(-1) = 3(-1)^2 - 5 = 3 - 5 = -2

f(a) = f(-3) = 3(-3)^2 - 5 =27 - 5 = 22

f(b) - f(a) = -2 - 22 = -24

b - a = -1 + 3 = 2

When a child is born, her grandfather decides to put $100 in an account that earns interest. He plans to make no other deposits or withdrawals for 18 years. When the child turns 18 years old, the money in the account will be a birthday gift. The grandfather is choosing between two options:

Option 1: An account that grows by 10.5% each year.
Option 2: An account that grows by $20 each year.

Which option will result in a better 18th birthday gift? Explain your reasoning.

Answers

Answer:

option (1) is a better 18th Birthday gift of child by Grandfather.

Step-by-step explanation:

Amount deposited in bank at time of birth by Grandfather is $100.

And there is no other deposits and withdrawals for 18 years.

So,

                          Principal amount =$100

                                             Time = 18 years

              Rate of interest of bank = 10.5%

Option 1:- An account That grows by 10.5% each year

we know that Bank give compound interest on the deposit amount

then                   Compound interest = C.I=P(1+r) with an exponent of t

                                  C.I= 100(1 + 10.5 over 100)with an exponent of 18

                                  C.I= 100*6.0328

                                  C.I= $603.28

Option 2:- An account that grows by $20 each year

Here,

                   Amount credited in account for 18 years = $20

So,                Total amount after completion of 18 years = 10+18*20

                                                                                         =460

Hope this helped <3

The child turns 18 years old, and the money in the account will be a birthday gift is a better 18th Birthday gift for a child by a Grandfather.

The amount deposited in the bank at the time of birth by Grandfather is $100.

And there is no other deposits and withdrawals for 18 years.

Principal amount =$100

Time = 18 years

Rate of interest of bank = 10.5%

Option 1:- An account That grows by 10.5% each year

We know that Bank give compound interest on the deposit amount

What is the formula for compound interest?

Compound interest = C.I=P(1+r) with an exponent of t

C.I= 100(1 + 10.5 over 100)with an exponent of 18

C.I= 100*6.0328

C.I= $603.28

An account that grows by $20 each year

The amount credited in the account for 18 years = $20

The total amount after completion of 18 years = 10+18*20

 The total amount after completion of 18 years=460
