A 0.40 kg bird is flying at a constant speed of 8.0 m/s. What is the bird's kinetic energy?

Answers

Answer 1

Answer:

The correct answer is 12.8 J.

Step-by-step explanation:

To solve this problem, we must remember how to calculate the kinetic energy of an object.

The kinetic energy is represented by the formula K = 1/2 * m * v^2, where m represents the mass of the object and v represents the speed or velocity of the object.  If we plug in the given values into the formula, we get:

K = 1/2 * m * v^2

K = (1/2) * (0.40) * (8.0)^2

Our first step is to square the velocity.  After doing this step, we get the following:

K = (1/2) * (0.40) * (64)

Finally, we can perform the multiplication, to get:

K = 12.8

The unit for kinetic energy is joules, so the correct answer is 12.8 J.

Hope this helps!

Answer 2

Kinetic energy is the energy due to motion of an object

The kinetic energy of the bird is 12.5 joules

Reason:

The known parameter are;

The mass of the bird, m = 0.50 kg

The speed of the bird, v = 8.0 m/s

Required:

To find the kinetic energy of the bird

Solution:

[tex]Kinetic \ energy = \dfrac{1}{2} \cdot m \cdot v^2[/tex]

Therefore;

[tex]The \ kinetic \ energy \ of \ the \ bird = \dfrac{1}{2} \times 0.40 \ kg \times (8.0 \ m/s)^2 = 12.8 \ J[/tex]

The kinetic energy of the bird is 12.8 J

During a vacation together bob spent twice as much as Josh who spent four times as much as Ralph. If Bob and Ralph together spent $180 how much did josh spend

Answers

Answer:

Step-by-step explanation:

Bob: 8x

Josh: 4x

Ralph: x

8x + x = 180

9x = 180

X= 20

Josh:

X = 20

Multiply it by 4

X =80

Josh spent $80

The amount of money spent by Bob, Josh, and Ralph will be $160, $80, and $20.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

During a vacation together, Bob spent twice as much as Josh, who spent four times as much as Ralph.

Let x be the amount of money spent by Ralph.

Then Bob spent 8x and Josh spent 4x.

If Bob and Ralph together spent $180. Then the equation will be

8x + x = 180

     9x = 180

       x = 180 / 9

       x = $20

Then the money spent by Bob and Josh will be

Bob = 8x = 8 × 20 = $160

Josh = 4x = 4 × 20 = $80

Then the amount of money spent by Bob, Josh, and Ralph will be $160, $80, and $20.

Step-by-step explanation:

The tangent- secant angle x is half the difference of the measures of the intercepted arcs, that is

[tex]\frac{1}{2}[/tex] (4x + 5 - 50 ) = x ( multiply both sides by 2 )

4x - 45 = 2x ( subtract 2x from both sides )

2x = 45 ( divide both sides by 2 )

x = 22.5

Given expression is

[tex](\frac{4m^{-2}n^8}{9m^{-6}n^{-8}} )^{\frac{1}{2}[/tex]

The correct simplified form is shown below:-

From the above equation, we will simplify

we will shift [tex]m^{-6}[/tex] to the numerator and we will use the negative exponent rule, that is

[tex]= (\frac{4m^{-2}n^8m^6}{9n^{-8}} )^{\frac{1}{2}[/tex]

[tex]= (\frac{4m^{-2}n^8m^6n^8}{9} )^{\frac{1}{2}[/tex]

here we will solve the above equation which is shown below

[tex]= (\frac{4m^4n^{16}}{9}) ^\frac{1}{2}[/tex]

So,

[tex]= (\frac{(2)^2(m^2)^2(n^8)^2}{(3)^2} ^\frac{1}{2}[/tex]

Prove theorems about triangles

Answers

a) It is possible and it is the only proper value of angle 2

b) Explanation Below

Angle 1 adds to the two other internal angles to get 180

(angle1) + 30 + 42 = 180

angle1 + 72 = 180

angle1 = 180-72

angle1 = 108 degrees

Subtract this from 180 to find the measure of angle 2

angle2 = 180 - angle1

angle2 = 180-108

angle2 = 72

A shortcut is to use the remote interior angle theorem to add up the interior angles 30 and 42 to get 72 as our exterior angle that is not adjacent to any of the interior angles we just added. Hence the "remote" portion.

a) possible
b) justification
Step 1: find value of angle 1
- you know the angles inside a triangle add up to 180 deg.
- add up the inside angles
30 + 42 + x = 180
(x=angle 1)
- x = 180-72
- x = 108
- angle 1 = 108

Step 2: Notice that angle 1 and angle 2 are supplementary (they have to add up to 180) because they are on a straight line.
- 108+x=180
(x = angle 2)
- x= 180 - 108
- x= 72 (proof complete)

Answers

Answer:

Solution:

[tex]\frac{\left(y-1\right)^2}{9}-\frac{\left(x+4\right)^2}{4}=1[/tex]

Step-by-step explanation:

We have the general equation for our up - down facing hyperbola as (y - k)² / b²- (x - h)² / a²  = 1. Let's start listing the properties of this graph -

• Taking a look at the graph we see that the center point of our hyperbola here is (- 4, 1). Therefore (h, k) = (- 4,1).

• Another thing here is our key value a. This is the semi distance from the center to one of the vertices. Here it will be the distance from points (- 4,1) and (- 4,4) or 3 unit difference. Therefore a = 3.

• That leaves us with our asymptotes. Now remember that it will be in the form y = ± b / a. We already know a = 3, so we have to find b. Looking at this graph I can say that another point besides (- 4,1) that lies on the " dotted line " is (- 2, - 2). Calculating the slope of the dotted line would be as follows,

Given: (- 4,1) and (- 2, - 2)

Slope = - 2 + 4 / - 2 - 1 = 2 / 3

We have the equation y = 2 / 3x. Therefore b = 2. Let's substitute to receive our equation...

h = - 4, k = 1, b = 2, a = 3

(y - 1)² / (3)²- (x + 4)² / (2)²  = 1

(y - 1)² / 9 - (x + 4)² / 4  = 1 ~ your solution is the last one, option d
