Whats the rate of change for (0,3) and (2,-5)

Answers

Answer 1

Answer:

[tex]\boxed{\sf{-4}}[/tex]

Step-by-step explanation:

Solve a slope using a rate of change.

Slope:

[tex]\sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{rise}{run} }[/tex]

⇒ y2=(-5)

⇒ y1=3

⇒ x2=2

⇒ x1=0

Rewrite the problem down.

⇒ (-5)-3/2-0

Solve.

⇒ -8/2

Divide.

⇒ -8/2=-4

Therefore the slope is -4, which is our answer.

I hope this helps you! Let me know if my answer is wrong or not.

At his schools book fair, Henry brings $10.00. He purchases a book for $8.50, plus a 6% sales tax. How much money in change will Henry receive?

Answers

8.50 * 0.06 = 0.51

0.51 + 8.50 = 9.01

10.00 - 9.01 = 99

He will receive 99 cents in change.

Answer:

$0.99 in change

Explanation:

To apply the sales tax, you have to multiply:

8.50*1.06=9.01

This means that, with tax, the book will cost $9.01. If he gave them $10, he would get 99 cents back because 10-9.01 is 0.99.

Which probability describes an event that is “very likely”?

A. 0.125
B. 0.9
C. 1
D. 0.50

Answers

The answer is B. 0.9
Explanation:
If you multiply all the choice with 100the results will be
A.12.5%
B.90%
C.100%
D.50
So a situation which is very likely to happen will be 90% ( 100% is not correct because it means that the situation is gonna happen and is accurate but when you say very likely to happen it means there is still a low chance for a situation not to happen)

The probability that describes an event as "very likely" is option B, 0.9.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a numerical value between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that an event is certain.

A probability of 0.9 means that there is a 90% chance that the event will occur, which is a high likelihood of the event happening. In general, probabilities between 0.7 and 1 are often considered to be "likely" or "very likely".

Therefore, the correct option is B.

The length of a rectangle is three times its width.
If the perimeter of the rectangle is 64 cm, find its length and width.

Answers

Answer:

Length: 24 cm

Width: 8 cm

Explanation:

Let Width be "w"

Then Length is "3w"

=================

Perimeter of rectangle = 2(length+width)

===================================

2(3w+w) = 64(4w) = 32w = 8

So, width is 8 cm

Length: 3w ⇒ 3(8) ⇒ 24 cm

The sine model for the height (in feet) of the end of one windmill blade as a function of time t (in seconds) y = 30sin(π/15t)+30.

What is sine function with time?

The period of a sine function is equal to the 2π and it repeats after each 2π units.

The  sine model can be given as,

[tex]y = a\sin(bt) +k[/tex]

The blades are 10 feet long and complete 2 rotations every minute. Thus the period is,

[tex]b=\dfrac{2\pi}{60}\times2\\b=\dfrac{\pi}{15}\\[/tex]

The blades of a windmill turn on an axis that is 30 feet from the ground. Thus,

[tex]k=30[/tex]

The blades are 10 feet long. Thus,

[tex]a=10[/tex]

Put these values in the above formula as,

[tex]y = 30\sin(\dfrac{\pi}{15}t) +30[/tex]

Thus, the sine model for the height (in feet) of the end of one windmill blade as a function of time t (in seconds) y = 30sin(π/15t)+30.

Answers

Answer:

(- 5, 9)

Step-by-step explanation:

Given system of equations

- 2x - y = 1- 4x - y = 11

Express the first equation as

y = - 2x - 1

Substitute the value of y into second equation

- 4x - (- 2x - 1) = 11

Solve for x

- 4x + 2x + 1 = 11- 2x + 1 = 11- 2x = 102x = - 10x = - 5

Find the value of y

y = - 2(- 5) - 1 = 10 - 1 = 9

Answer:

(-5, 9)

Step-by-step explanation:

Given system of linear equations:

[tex]\begin{cases}-2x-y=1\\-4x-y=11\end{cases}[/tex]

To solve by substitution, use arithmetic operations to isolate y in Equation 1:

[tex]\implies -2x-y=1[/tex]

[tex]\implies -2x-y+y=1+y[/tex]

[tex]\implies -2x=1+y[/tex]

[tex]\implies -2x-1=1+y-1[/tex]

[tex]\implies y=-2x-1[/tex]

Substitute the expression for y into Equation 2 and solve for x:

[tex]\implies -4x-(-2x-1)=11[/tex]

[tex]\implies -4x+2x+1=11[/tex]

[tex]\implies -2x+1=11[/tex]

[tex]\implies -2x+1-1=11-1[/tex]

[tex]\implies -2x=10[/tex]

[tex]\implies -2x \div -2=10 \div -2[/tex]

[tex]\implies x=-5[/tex]

Substitute the found value of x into one of the equations and solve for y:

[tex]\implies -2(-5)-y=1[/tex]

[tex]\implies 10-y=1[/tex]

[tex]\implies 10-y+y=1+y[/tex]

[tex]\implies 10=1+y[/tex]

[tex]\implies 10-1=1+y-1[/tex]

[tex]\implies y=9[/tex]

Therefore, the solution to the given system of linear equations is (-5, 9).
