D.0

Answers

Answer 1

Answer:

It is 0

Step-by-step explanation:

Unlike the positive side of the number line which increases its value as it goes up in numbers, the negative side of a number line increases its value as it goes goes down in numbers as the more closer a negative number is to the positive side of infinity, the greater value it has. In this instance, zero is the greater number than -6 and all other negative numbers.

an elevator in a hotel moves at 20 feet per second. leaving form the ground floor, its height in feet after t second is given by the formula h(t)=20t. a bolt comes loose in the elevator shaft above, and its height in feet after falling for t second is given by h(t)=-16t^2+200. at what time and at what height does the bolt hit the elevator?​

Answers

After 3 seconds and at 60 feet, the bolt hit the elevator if the height in feet after t second is given by the formula h(t)=20t.

What is a quadratic equation?

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

When the bolt hit the elevator, they would be at the same height.

∴ 16t²+200 = 20t

16t² -20t + 200 = 0

It is a quadratic equation:

a = 16, b = -20, and c = 200 plug this values in the formula.

After calculating, we will get:

t = -4.2 or t = 3

Time cannot be negative.

So t = 3 seconds

And height h(3) = 20(3) = 60 feet

Thus, after 3 seconds and at 60 feet, the bolt hit the elevator if the height in feet after t second is given by the formula h(t)=20t.

You are given the system of equations to solve by the elimination method, which is an INCORRECT step that will NOT produce a system with the same solution? 3x + 3y = 4 18x − 9y = 12 A) multiply the first equation by 6 and subtract the second equation B) multiply the first equation by −6 and add the second equation C) multiply 3x by 6 in the first equation and subtract the second equation D) add 2 times the first equation and −1/3 times the second equation Eliminate

Answers

C would be the correct answer. You caanot multiply just one part of an equation, you must multiply the whole thing. All of the other steps follow this rule, so C is an incorrect step, and is therefore the correct choice.

Hope this helps!

Answer:

C) Multiply 3x by 6 in the first equation and subtract the second equation.

Step-by-step explanation:

We have been given a system of equations.[tex]3x+3y = 4[/tex] and [tex]18x-9y = 12[/tex]. We are asked to choose the "incorrect" step that will make "not" produce a system with the same solution.

Let us see our give choices one by one.

A) multiply the first equation by 6 and subtract the second equation.

When we will multiply 1st equation by 6, the coefficient of x would be 18. When we will subtract 2nd equation the both x's will cancel out. Therefore, option A is correct.

B) multiply the first equation by −6 and add the second equation.

When we will multiply 1st equation by -6, the coefficient of x would be -18. When we will add 1st equation to 2nd equation the both x's will cancel out. Therefore, option B is correct as well.

C) Multiply 3x by 6 in the first equation and subtract the second equation.

We need to remember that we cannot multiply only one term of equation by some quantity as it will make the whole equation false, therefore, option C is incorrect.

What is the total number of different 6-letter arrangements that can be formed using the letters in the word QUASAR?

Answers

Final answer:

There are 720 different 6-letter arrangements that can be formed using the letters in the word QUASAR, calculated by 6 factorial (6!).

Explanation:

The question asks for the total number of different 6-letter arrangements that can be formed using the letters in the word QUASAR. This is a problem of permutations where all the letters are distinct. To find the number of different permutations of the letters in QUASAR, we multiply the number of choices available at each position. There are 6 choices for the first letter, 5 for the second, and so on, until 1 choice for the last letter.

Therefore, the permutations are calculated as 6 × 5 × 4 × 3 × 2 × 1, which is equal to 6! (6 factorial).

The calculation of 6! is as follows:

6 × 5 × 4 × 3 × 2 × 1 = 720.

So, there are 720 different 6-letter arrangements that can be formed from the word QUASAR.

what are the next three terms in the sequence -1, 9, 19, 29

Answers

39. each term is ten more than the term before it :)

Answer:

39, 49, 59

Step-by-step explanation:

Note the difference between consecutive terms

9 - (- 1) = 9 + 1 = 10

19 - 9 = 10

29 - 9 = 10

The difference is a constant + 10

To obtain the next term in the sequence add 10 to the previous term

29 + 10 = 39

39 + 10 = 49

49 + 10 = 59

The next 3 terms are 39, 49, 59

Step-by-step explanation:

The given complex number are:

[tex]z_1=-3\sqrt{3}+3i[/tex]

and

[tex]z_2=6\cos 150\degree+6i\sin 150\degree[/tex]

When we rewrite [tex]z_1=-3\sqrt{3}+3i[/tex] in complex form, we obtain;

[tex]z_1=r(\cos \theta+i\sin \theta)[/tex]

where

[tex]r=\sqrt{(-3\sqrt{3})^2+3^2 }=\sqrt{36}=6[/tex]

and

[tex]\theta=tan^{-1}(\frac{y}{x})[/tex]

[tex]\implies \theta=tan^{-1}(\frac{-3\sqrt{3}}{3})=150\degree[/tex]

Hence,

[tex]z_1=6(\cos 150\degree+i\sin 150\degree)[/tex]

[tex]z_1=6\cos 150\degree+6i\sin 150\degree[/tex]

Making Equivalent Fractions :

5.3 Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

L. Mult. • L. Num. (18n-7)

Step 6 :

When a fraction equals zero :

6.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

6n-17

————— • 6 = 0 • 6

6

Now, on the left hand side, the 6 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

6n-17 = 0

Solving a Single Variable Equation :

6.2 Solve : 6n-17 = 0

Add 17 to both sides of the equation :

6n = 17

Divide both sides of the equation by 6:

n = 17/6 = 2.833

Substitute:

[tex]x^2+20.2^2=(14.7+x)^2[/tex]           use (a + b)² = a² + 2ab + b²

[tex]x^2+408.04=14.7^2+(2)(14.7)(x)+x^2[/tex]          subtract x² from both sides

There are infinitely many solutions.  It is the same line.

Step-by-step explanation:

If you start by multiplying the first equation by 2 to get rid of the fractions, you get -x + y = -2.  If you solve it for y, you get y = x - 2.  The second equation can be solved for y also, giving you y = x - 2.  That means they are the same line and the solution to this situation is infinitely many solutions because all the points on one line are identical to the points on the other line because they are the same line.

Answer:

His money earned $36 after 3 months

Step-by-step explanation:

* Lets revise the rules of simple interest

- Simple Interest Equation (Principal + Interest)

 A = P(1 + rt)

- Where:

• A = Total amount (principal + interest)  future amount

• P = Principal Amount

• I = Interest Amount

• r = Rate of Interest per year in decimal; r = R/100

• t = Time Period involved  

* To calculate the interest I use the formula

  I = P × r × t

* Lets solve the problem

- The rate is annual

- The interest calculated after 3 months

∴ I = P × R/100 × t/12

∵ P = $3600.00

∵ R = 4%

∵ t = 3 month

∴ I = 3600.00 × 4/100 × 3/12 = $36

* His money earned $36 after 3 months

Explain what type of function is the best model for the data set and justify your choice. Help???????

Answers

Answer:

The function is linear

Step-by-step explanation:

* Lets check from the table the type of the function

- At first check if it is linear or not

- The points are:

  (165 , 198) , (168 , 201.6) , (170 , 204) , (172 , 206.4) , (175 , 210)

* Find the slope for each two points if the value of the slop is

 constant, then the function will be linear

∵ The slop = (y2 - y1)/(x2 - x1)

∴ m1 = (201.6 - 198)/(168 - 165) = 1.2

∴ m2 = (204 - 201.6)/(170 - 168) = 1.2

∴ m3 = (206.4 - 204)/(172 - 170) = 1.2

∴ m4 = (210 - 206.4)/(175 - 172) = 1.2

∵ m1 = m2 = m3 = m4

# Note: You can use any to points to find the slope you will

  have the same value

∴ The graph of the points is a line with slope 1.2

* The function is linear
