(-1,4) and ( 1, -1) Find the distance between each pair of points

Answers

Answer:

[tex]\sqrt{29}[/tex]

Step-by-step explanation:

We are basically trying to find the hypotenuse of the triangle.

The distance between the x is 2, and the distance between the y is 5, which makes a length and a width.

Pythagrenum theorem: a^2+b^2=c^2

2^2 is 4, 5^2 is 25.

4+25 is 29.

The distance is [tex]\sqrt{29}[/tex].

Mr. Shaw wants to replace the flooring his family room. The floor has an area of 262.8 square feet. If the room is 18 feet long, how wide is it? Justify your procedure.

Answers

Answer:

14.6

Step-by-step explanation:

The area of a rectangle is area=length*width

so we can substitute the numbers here, 262.8=18w

divide 262.8 by 18 to isolate the variable.

You get 14.6.

The width is 14.6.

Round off 54.3223 to 1 decimal place

Answers

Answer:

54.3

Step-by-step explanation:

since it is mentioned 54.3223, then u should see the two decimal places as they are asking to round it off to one decimal place. so we should see 54.32 only

if the second decimal is less than 5, then you should write the first decimal as it is like the above mentioned question (remember we are only supposed to mention one decimal place)

but if it is 5 or more, then you should move the first decimal to the next number. for example, 54.678. for this you should write 54.7 because the second decimal is more than 5

if they are asking to round it off to 3 places then you should see 4 decimal places

6x-18=54 what does the x represent

Answers

Answer:

x=12

Step-by-step explanation:

I attached a picture for the steps

Simplifying

6x + -18 = 54

Reorder the terms:

-18 + 6x = 54

Solving

-18 + 6x = 54

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '18' to each side of the equation.

-18 + 18 + 6x = 54 + 18

Combine like terms: -18 + 18 = 0

0 + 6x = 54 + 18

6x = 54 + 18

Combine like terms: 54 + 18 = 72

6x = 72

Divide each side by '6'.

x = 12

Simplifying

x = 12

Final Result: 12

As a estimation we are told £3 is €4. Convert £25.50 to euros €

Answers

Answer:

£34

Step-by-step explanation:

→ Find how euros is in a pound

£3 = €4

£1 = €1.33

→ Multiply the euro by 25.50

1.33333 × 25.50 = £34

Answer:

€34

Step-by-step explanation:

First you'll want to find out how much £1 is.

Since we know £3 is equal to €4 we can:

divide £3 by 3 = £1divide €4 by 3 = €1.33

So, £1 = €1.33

With this in mind, we can find out what £25.50 is:

£1 x 25.50 = £25.50€1.33 x 25.50 = €34

Therefore, £25.50 = €34

D is the answer because it shows a function of y=2x+1
2x1=2+1=3
2x2=4+1=5
2x4=8+1=9
2x5=10+1=11

Answer:  D.)  y = 2x + 1

Step-by-step explanation:

in slope-intercept form, y = mx + b, m is the slope, Rise/Run

The difference in y-values, rise,  increases by 2  for every increase of 1 in x-values, the run.

2/1 is the slope

m = 2

b is the y-intercept

To calculate b, substitute any pair of y and x values from the chart, and the value 2 for m:

9 = 4(2) + b

9 = 8 + b

1 = b  

Rewrite the equation with the values calculated for m and b. Keep y and x

y = 2x + 1

Find the average rate of change for f(x) = x^2 − 3x − 10 from x = −5 to x = 10.
A) -1
B) -2
C) 1
D) 2

Answers

Answer:

D) 2

The average rate of change of f(x)

A(x) =2

Step-by-step explanation:

Step(i):-

Given that the function f(x) = x² - 3x -10

Given x =a = -5   and y = b = 10

The average rate of change of f(x)

[tex]A(x) = \frac{f(b)-f(a)}{b-a}[/tex]

Step(ii):-

f(x) = x² - 3x -10

f(-5) = (-5)² - 3(-5) -10 = 25+15-10=30

f(10) = (10)² -3(10)-10 = 100 -30 -10 =60

The average rate of change of f(x)

[tex]A(x) = \frac{f(b)-f(a)}{b-a}[/tex]

[tex]A(x) = \frac{60-30}{10-(-5)}= \frac{30}{15} = 2[/tex]

A(x) =2

A jet travels 470 miles in 2 hours. At this rate, how far could the jet fly in 11 hours?

Answers

Answer:

The jet will cover 2585 miles in 11 hours.

Step-by-step explanation:

Given that:

Distance travelled by jet in 2 hours = 470 miles

Speed of jet = [tex]\frac{Distance}{Time}[/tex]

Speed of jet = 470/2

Speed of jet = 235 miles per hour

Time = 11 hours

Distance travelled in 11 hours = Speed * Time

Distance = 235 * 11

Distance = 2585 miles

Hence,

The jet will cover 2585 miles in 11 hours.
