Graph means a pictorial representation or a diagram that represents data or values in an organized manner.

Given,

Question 6

Six customers are buying gasoline at Miguel's Gasoline Station. The number of gallons bought and the total cost of their purchases are plotted on the graph.

Here we need to find the price per gallon at Miguel's Gasoline Station.

In order to find the price, we have to take the points from the given graph.

Then we the points as, (4,10) and (9, 22)

By looking in the graph, the plotted points will form the straight line on the graph.

So, we have to use the formula for straight line to find the cost on one liter,

For, that we have to find the following,

m = (22 - 10) / (9 - 4)

m = 12/5

And the value of y intercept is,

10 = 12/5 (4) + c

50 = 48 + c

c = 2

The equation for the graph is y = 12/5x + 2

Therefore, the cost of 1 liter of the material is,

y = 12/5 (1) + 2

y = 12/5 + 2

y = 12+10/5

y = 22/5

Therefore, the cost is 4.4.

The area of the shaded circular region is 197.82 unit².

The space a circle takes up on a two-dimensional plane is known as the area of the circle. The region contained within the circle's circumference or perimeter is another way to define the circle's area.  A = πr², where r is the circle's radius, is the formula for calculating a circle's surface area.

The radius of the inner circle = 9 units

So, the area of the inner circle is given by

a = πr²

= 3.14 × 9²

= 3.14 × 81

= 254.34 unit²

The radius of the outer circle = 12 units

So, the outer circle area is given by

A = πR²

= 3.14 × 12²

= 3.14 × 144

= 452.16 unit²

So, the area of the circular shaded region is given by

Area = area of the outer circle - an area of the inner circle

Answer:

  2.76×10^-3 m/s²

Step-by-step explanation:

You want to know the acceleration of the moon toward the Earth, given its distance is 3.8×10^8 meters, Earth's mass is 5.98×10^24 kg, and the gravitational constant is 6.673×10^-11 N·m²/kg².

The acceleration of one body by another is ...

  a = GM/r²

where G is the gravitational constant, M is the body creating the gravitational field, and r is the distance between the masses.

  a = (6.673×10^-11)(5.98×10^24)/(3.8×10^8)² N/kg

  a = (6.673·5.98/3.8²)×10^(-11+24-16) m/s² ≈ 2.76×10^-3 m/s²

1. A = 45°         B = 110°

2. B = 88°        C = 44°

3. A = 59°        B = 48°        C= 73°

4. The measure of the exterior angle is 108°

5. The tornado's direction needs to change by 30°

The sum of interior angles of triangle is always equal to 180°.

Now let's apply it in the given questions.

1. A = x

B = x + 65

C = 25

So, x + x + 65 + 25 = 180

2x = 180 - 90

x = 90/2

x = 45°

2. x + 48 + x - 44 = 180

2x = 180 - 4

x = 176/2

x = 88°

3. x + 73 + x - 11 = 180

2x = 180 - 62

x = 118/2

x = 59°

4. Let the third interior angle be b.

2a + b = 180

b = 180 - 2a

now by applying angle sum property

a + 10 + 44 + 180 - 2a = 180

2a - a = 54

a = 54°

the exterior angle is 2a that is 54*2 = 108°

5. For the tornado to deviate and pass through radar station instead of cell phone tower the angle that needs to be made will be nothing but the third interior angle of the triangle as the tornado is at the vertex.

Step #1:  Find the slope of the given line.

To do this, solve the equation for slope-intercept form:

         x + 2y = 16

               2y = -x + 16

                 y = -1/2 x +8

The slope of this line is -1/2.

Step #2: Find the slope of the new line.

To be perpendicular, the other line needs a slope that is the opposite reciprocal slope.  So, that'd be +2/1 or just 2.

Step #3: Find n.

Now, you know m=2 and we also have the slope formula

         m = (y2 - y1) / (x2 - x1)

Using the two points (-9,n) and (1,5n), we can set up:

         2 = (5n - n) / (1 - (-9))

         2 = 4n / 10

         2 = 2n/5

Multiply by 5 and divide by 2:

         10 = 2n

         5 = n

The process was: find the slope of the given line, use that to find the slope of the perpendicular line, and then use and the slope formula to find n.

The distance between the two points (5,-3,-4) and (-1,-2,7) is:

d = √158

So the correct option is the last one.

The distance between two points (x₁, y₁, z₁) and (x₂, y₂, z₂) is given by:

distance = √( (x₁ - x₂)² + (y₁ - y₂)² + (z₁ - z₂)²)

Here we want to find the distance between the two points (5,-3,-4) and (-1,-2,7), using the above formula we will get:

d =  √( (5 + 1)² + (-3 + 2)² + (-4 - 7)²)

d =  √( (6)² + (-1)² + (-11)²)

d =  √( 36 + 1  + 121)

d = √158
