1760J

Step-by-step explanation:

Given parameters:

   Mass of rock  = 55kg

    Velocity  = 8m/s

Unknown:

Kinetic energy  = ?

Solution:

The kinetic energy of a body is the energy to motion of a body.

   K.E = [tex]\frac{1}{2}[/tex] m v²  

where m is the mass and v is the velocity

Insert the parameters and solve;

  K.E = [tex]\frac{1}{2}[/tex] x 55 x 8²   = 1760J

Answer:

The equation could be used to determine the total production costs for the company if it produced x widgets last month is

y = $8,906.00 + $2.64x ⇒ B

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

∵ A company has fixed costs of $8,906.00 each month

→ That means it is a fixed value every month

∴ b = 8,906.00

∵ The cost of each widget it produces is $2.64 for

→ That means the value is changing according to the number of widgets

∴ m = 2.64

∵ y represents the total costs of production last month

∵ x represents the number of widgets the factory produced last month

→ Substitute the values of m and b in the form of the equation above

∴ y = 2.64x + 8,906.00

The equation could be used to determine the total production costs for the company if it produced x widgets last month is

y = $8,906.00 + $2.64x

Answer:

5:12

Step-by-step explanation:

5 to 12

Answer:

Yes it is.

Step-by-step explanation:

(1, -4) means that x = 1 and y = -4.

Use those values, substitute, and solve.

y = -4x

-4 = -4(1)

-4 = -4 TRUE

α & β are the zeroes of 2x² - 5x + 7.

polynomial whose zeroes are 2α + 3β , 2β + 3α .

On comparing with the standard form of a quadratic equation,

Let,

a = 2

b = - 5

c = 7.

We know that,

Sum of the zeroes = - b/a

⟹ α + β = - ( - 5)/2

⟹ α + β = 5/2 -- equation (1)

Product of the zeroes = c/a

⟹ αβ = 7/2 -- equation (2)

Now,

General form of a Quadratic equation is x² - (sum of the zeroes)x + product of the zeroes = 0.

★ Sum of the zeroes = 2α + 3β + 2β + 3α

⟹ Sum of the zeroes = 5α + 5β

⟹ Sum of the zeroes = 5(α + β)

Putting the value from equation (1).

⟹ Sum of the zeroes = 5(5/2)

⟹ Sum of the zeroes = 25/2

Similarly,

★ Product of the zeroes = (2α + 3β)*(2β + 3α)

⟹ Product of the zeroes = 2α( 2β + 3α) + 3β( 2β + 3α )

⟹ Product of the zeroes = 4αβ + 6α² + 6β² + 9αβ

⟹ Product of the zeroes = 13αβ + 6(α² + β²)

a² + b² = (a + b)² - 2ab → α² + β² = (α + β)² - 2αβ

⟹ Product of the zeroes = 13αβ + 6[ (α + β)² - 2αβ ]

Putting the values from equations (1) & (2) we get,

⟹ Product of the zeroes = 13(7/2) + 6 [ (5/2)² - 2(7/2) ]

⟹ Product of the zeroes = 91/2 + 6 ( 25/4 - 14/2 )

Taking LCM we get,

⟹ Product of the zeroes = ( 2 * 91 + 6 * 25 + 2 * 14 ) /2

⟹ Product of the zeroes = (182 + 150 + 28 )/2

⟹ Product of the zeroes = 180

Hence,

New quadratic equation = x² - (25/2) * x + 180 = 0

⟹ New quadratic equation = (2x² - 25x + 360)/2 = 0

⟹ New quadratic equation = 2x² - 25x + 360 = 0

∴ The required quadratic equation is 2x² - 25x + 360 = 0.

I hope it will help you.

Answer:

For the line parallel to the line it has a gradient of -7 and the one perpendicular to the line has a gradient of 1/7.

Answer:

Parallel: m = -7

Perpendicular: 1/7

Step-by-step explanation:

The question is asking us to find the slope of the lines that are parallel and perpendicular to the one whose slope is -7.

Main Idea: Parallel lines have equal slopes; perpendicular lines have slopes that are opposite reciprocals.

The slope of the line that's parallel to the one whose slope is -7 is also -7.

The one that's perpendicular to it is the opposite reciprocal of -7, which is 1/7.

Therefore, this is the answer.

Use the vertical line test to determine if the graph is a function or not a function.

On a coordinate plane, a graph decreases to a minimum point, and then increases.

✔ function

On a coordinate plane, a graph increases to a maximum, decreases to a minimum, increases to the maximum, and decreases again to the minimum.

✔ function

On a coordinate plane, a graph decreases to the right, then decreases to the left, then decreases to the right.

✔ not a function

Step-by-step explanation:

As per the concept of the vertical line test, the third graph is not a function.

But the First and Second graphs represent a function.

The vertical line test is a method used to determine if a graph represents a function. It involves visually inspecting the graph and checking if any vertical line intersects the graph at more than one point.

Let's apply the vertical line test to the given graphs:

First graph:

For the first graph, if we draw any vertical line, it will intersect the graph at most once. Hence, the graph passes the vertical line test, indicating that it represents a function.

Second graph:

For the first graph, if we draw any vertical line, it will intersect the graph at most once. Hence, the graph passes the vertical line test, indicating that it represents a function.

Third graph:

The vertical line test is given in the image below.

In conclusion:

The third graph is not a function.

Answer: $460

Step-by-step explanation:

It cost $180/per week. The family will have the car for 2 weeks, so:

($180)(2)= 360

Additionally, it is $0.25 per mile. The family traveled 400 miles, so:

($0.25)(400)= 100

In total:

$360 + $100 = $460

Answer: A coordinate plane with straight line. The line starts at (negative 4, negative 5) and passes through points at (0, 0) and (4, 5). That is the answer.

A coordinate plane with straight line. The line starts at (negative 5, negative 2) and passes through points at (negative 1, 0) and (4, 5).

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as,

The slope of line is the measure of steepness or the direction of line the coordinate plane.

m = Δy/Δx

where,m is the slope

tan θ = Δy/Δx

We also refer this tan θ to be the slope of the line.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane. Calculating the slope of a line is similar to finding the slope between two different points. In general, to find the slope of a line, we need to have the values of any two different coordinates on the line.

Given:

slope= 4/5

The graph which show the slope 4/5 is:

A coordinate plane with straight line. The line starts at (negative 5, negative 2) and passes through points at (negative 1, 0) and (4, 5).

The only graph showing

slope= rise/run = 4/5

Answer:

Its asa

Step-by-step explanation:

Answer:

The answer to your question is the ASA(Angle-Side-Angle) postulate

Step-by-step explanation:

The reason this is not HL(hypotenuse leg) is because only one side, and two angles are marked as congruent, you need a congruent(equal measure) leg, hypotenuse, and right angle. In other words, you need a right triangle with a congruent hypotenuse, and leg ; tick marks, to indicate the sides have equal length(these are the slashes that go through the line or outline). An outline of the angle or tick on the outline corresponds to congruent angles.

Because you have two angles and a side, in the order of an angle then a side and then an angle, it is ASA.
