Answer:

**Answer:**

162 Joules

**Step-by-step explanation:**

Remember, the equation for the kinetic energy of an object is:

where m is the mass of the object in kg (kilograms), v is the velocity of the object in m/s (meters per second), and K is the kinetic energy of the object in J (joules).

We are given that the cat's mass is 4 kg. We will use this for m. We are also given that the cat is moving at 9 m/s. This would be it's speed. We can use this for velocity, or v. Plugging in we get:

So K, or the kinetic energy, would be 162J.

I hope you find my answer and explanation to be helpful. Happy studying.

Consider the following sample data: x 10 7 20 15 18 y 22 15 19 14 15 Click here for the Excel Data File a. Calculate the covariance between the variables. (Negative value should be indicated by a minus sign. Round your intermediate calculations to at least 4 decimal places and final answer to 2 decimal place

What is the median for the set of data shown below?16, 23, 24, 39, 45, 78, 95

The 3rd degree Taylor polynomial for cos(x) centered at a = π 2 is given by, cos(x) = − (x − π/2) + 1/6 (x − π/2)3 + R3(x). Using this, estimate cos(86°) correct to five decimal places.

An **exterior****angle** of ΔXYZ is ∠HXJ.

The correct option is D.

When two **lines** or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle **measure** in geometry is the length of the **angle** created by two rays or arms meeting at a common vertex.

As per the provided diagram, the exterior angles in the ΔXYZ are:

∠LXH,

∠MXJ,

∠HXJ,

∠OYK,

∠GZN,

∠MXZ,

∠YXL,

∠KYZ,

∠GZY.

From the given choices, ∠HXJ is an exterior angle of ΔXYZ.

Answer:

The answer is C, <JXZ.

Step-by-step explanation:

**Answer:**

x = 120

**Step-by-step explanation:**

An equilateral triangle has 3 equal angles

The sum of the angles is 180

180/3 = 60

x + 60 = 180 since they form a straight line

x = 180-60

x = 120

**Answer:**

X...................

cups all-purpose flour.

• 31/2 teaspoons baking powder.

• 1 teaspoon salt.

1 tablespoon white sugar.

• 1 1/4 cups milk.

• 1 egg.

• 3 tablespoons butter.

1.) How much of each of the ingredients do you need to make 16 pancakes, 4 pancakes, 12pancakes? Explain which operations with fractions you used to obtain your answer.

**Answer:**

To make 16 pancakes, we would multiply each of the initial measurement of the ingredients by 16.

To make 4 pancakes, we would multiply each of the initial measurement of the ingredients by 4.

To make 12 pancakes, we would multiply each of the initial measurement of the ingredients by 12.

see explanation below

**Step-by-step explanation:**

If the ingredients to make 1 pancake is as follows:

1 1/2 cups all-purpose flour; 31/2 teaspoons baking powder; 1 teaspoon salt.

1 tablespoon white sugar.; 1 1/4 cups milk; 1 egg; and 3 tablespoons butter.

Then to make 16 pancakes, we would multiply each of the initial measurement of the ingredients by 16.

cups all-purpose flour =16× 1 1/2

= 16×3/2 = 24

teaspoons baking powder = 16 ×7/2 = 56

teaspoon salt = 1×16 = 16

tablespoon white sugar= 1×16 = 16

cups milk= 16×5/4 = 20

egg= 1×16 = 16

tablespoons butter= 3×16 = 48

Then to make 4 pancakes, we would multiply each of the initial measurement of the ingredients by 4.

cups all-purpose flour =4× 1 1/2

= 4×3/2 = 6

teaspoons baking powder = 4 ×7/2 =14

teaspoon salt = 1×4 = 4

tablespoon white sugar= 1×4 = 4

cups milk= 4×5/4 = 5

egg= 1×4 = 4

tablespoons butter= 3×4 = 12

Then to make 12 pancakes, we would multiply each of the initial measurement of the ingredients by 12.

cups all-purpose flour =12× 1 1/2

= 12×3/2 = 18

teaspoons baking powder = 12 ×7/2 =42

teaspoon salt = 1×12 = 12

tablespoon white sugar= 1×12 = 12

cups milk= 12×5/4 = 15

egg= 1×12 = 12

tablespoons butter= 3×12 = 36

The operation applied is multiplication with each fraction.

B- The median score was 70 points.

C- 50% of the students scored below 70 points.

D- This would be a normal distribution.

**Answer: C) 50% of the students scored below 70%**

__Step-by-step explanation:__

Mean is the average. To find the mean (aka average) you add up all of the scores and divide by the number of tests.

B) The mean can be 70 without any test scoring 70% so B is not true.

A) Since B is not true, then A is not a valid option.

D) We don't know any of the other data so don't know if it is skewed left, skewed right, or normal. Therefore, option D is not true.

C) If the average is 70%, then half received grades above that score and half received grades below that score. So, option C is TRUE!

B. Locate the ordered pair (0, –6). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.

C. Locate the ordered pair (–6, 0). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.

D. Locate the ordered pair (–6, 0). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.

**Answer:**

A

**Step-by-step explanation:**

Slope is positive 2 so we have to move 1 point right and 2 points up.

Secondly y-intercept is -6 so ,point is (0,-6)

**Answer:**

x + 3

**Step-by-step explanation:**

Use the distributive property, then collect like terms

(1/2)(3/5 x) + (1/2)(-8) + (7/4)(2/5 x) + (7/4)(4)

3/10 x - 4 + 7/10 x + 7

x + 3
