What is the slope between the two points (8, -2) and (-7, 10)?

Answer:

508

Step-by-step explanation:

Take a = 12 and b = 8

[tex]\int\limits^a_b {3(f(x) - 2g(x)} \, dx =\int\limits^a_b {3(31) - 2(-17)} \, dx = 508[/tex]

Answer:

Step-by-step explanation:

By Pythagoras' Theorem, a² + b² = c².

Substituting the values of a and b, we get:

7² + 25² = c²

49 + 625 = c²

c² = 674

c ≈ 26.0 (to 1 d.p.)

Answer:

3500

(0,3500)

Step-by-step explanation:

The y - intercept of the line is at (0, 3500).

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have the line models the height of a glider [y] in feet over [x] hours

The y - intercept i.e. the point where the graph cuts the [y] axis. From the graph we can see that point is (0, 3500).

Therefore, the y - intercept of the line is at (0, 3500).

Answer:

≈83.33%

Step-by-step explanation:

400/480 = 5/6

56 * 100 =  ≈83.33%

Step-by-step explanation:

m= -3

y= -3x -2

......

the one on the right side (d)

at x= 2 y = 1

at x= 4 y = 2

1= 2m+b

2= 4m +b

subtract

1= 2m

m= 1/2

y= 1/2 x

Step-by-step explanation:

p=4

Q=2

plot an x onto the 4 on th y line and a 2 on the x line

then draw a horizontal line with the ruler provided through 4 and 2

hope it helps :)

The solution to the equations are

a) The coordinates of point P is P ( 0 , 4 ) and Q is Q ( 2 , 0 )

b) The graph is plotted with points P and Q

c) The equation of line is 4x + 2y = 8

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

4x + 2y = 8   be equation (1)

Now , the coordinates of the point P = P ( 0 , y )

The coordinates of the point Q = Q ( x , 0 )

Substituting the values in the equation , we get

when x = 0

4 ( 0 ) + 2y = 8

2y = 8

y = 4

So , the coordinates of the point P = P ( 0 , 4 )

when y = 0

4x + 2 ( 0 ) = 8

4x = 8

x = 2

So , the coordinates of the point Q = Q ( 2 , 0 )

Now , the equation of line is 4x + 2y = 8

when x = { -2 , -1 , 0 , 1 , 2 , 3 }

The values of y are y = { 8 , 6 , 4 , 2 , 0 }

So, the line is plotted in the graph

Hence , the equation of line is 4x + 2y = 8

To find:

The value of the given expression closest to the whole number.

Solution:

We have,

[tex]\dfrac{12\pi}{10\pi}\times \dfrac{5\pi}{6\pi}[/tex]

Cancel out the common factors from each fraction.

[tex]=\dfrac{6}{5}\times \dfrac{5}{6}[/tex]

[tex]=\dfrac{6\times 5}{5\times 6}[/tex]

An linear equation in one variable

Step-by-step explanation:

Variable:h

Equation:6h+19

Answer:

The average speed of the car, in miles per hour, from 17:30 to 19:42, is 119.167 meters per second.

Step-by-step explanation:

Physically speaking, average speed ([tex]\bar v[/tex]), measured in miles per hour, is the distance travelled ([tex]\Delta s[/tex]), measured in miles, divided by time ([tex]\Delta t[/tex]), measured in hours. That is:

[tex]\bar v = \frac{\Delta s}{\Delta t}[/tex] (1)

The time needed by the vehicle is:

[tex]\Delta t = 72\,min\times \frac{1\,h}{60\,min}[/tex]

[tex]\Delta t = 1.2\,h[/tex]

If we know that [tex]\Delta s = 143\,mi[/tex] and [tex]\Delta t = 1.2\,h[/tex], then the average velocity of the car is:

[tex]\bar v = \frac{143\,mi}{1.2\,h}[/tex]

[tex]\bar v = 119.167\,\frac{m}{s}[/tex]

The average speed of the car, in miles per hour, from 17:30 to 19:42, is 119.167 meters per second.

Answer:

1250

Step-by-step explanation:

The number of guest satisfaction surveys will you need to send out to make certain you receive at least 300 surveys back is 1,250.

Since the return is received i.e. 24%

And, there are the minimum of 300 surveys

So, based on this, the no of guest satisfaction should be

[tex]= 300 \div 0.24[/tex]

= 1,750

hence,  The number of guest satisfaction surveys will you need to send out to make certain you receive at least 300 surveys back is 1,250.

Answer:

Ivan receives £120 more than Tanya.

Step-by-step explanation:

Total Money = £ 150

Ratio = 4:1

This means that Ivan gets 4x of £150 and Tanya gets 1x of £150.

Ivan's money = 4x

Tanya's money = 1x

Now, we know that total money is equal to the sum of Ivan's & Tanya's money.

Total money = Ivan's money + Tanya's money

£ 150 = 4x + 1x

£ 150 = 5x

150/5 = x

30 = x.

We have found the value of x, now we can substitute 30 in the place of x and find the money Ivan and Tanya get.

Ivan = 4x = 4×30 = £120.

Tanya = 1x = 1×3 = £30.

So, Ivan receives more money. But how much more? We can solve that by subtracting Tanya's money from the total amount.

Total amount - Tanya's money = 150 - 30 = £120.

So, Ivan receives £120 more than Tanya.
