Find and identify the traces of the quadric surface x2 + y2 − z2 = 36 given the plane. x = k Find the trace. Incorrect: Your ans

AlekseyPX

Answer:

Hyperbola.

Step-by-step explanation:

We start from the function:

$x^{2} +y^{2} -z^{2} =36$

We may get the traces if we cut the surface in planes x=k. This is equivalent to replace x for k:

$k^{2}+y^{2} -z^{2}=36\\y^{2} -z^{2}=36-k^{2}$

The last equation is the equation of an hyperbola, which varies its characteristics depending on K (the plane cut).

Find the measure of the exterior angle in the following triangle. DUE SOON PLZ HELP WITH STEP BY STEP

PSYCHO15rus [73]

Answer:

The measure of an exterior angle = 125°

Hence, option A is correct.

Step-by-step explanation:

As the given triangle is a right-angled triangle ΔABC.

Given the angles

m∠A = 35°

m∠C = 90°

We know that the sum of angles in a triangle is 180°.

Thus,

m∠A + m∠B + m∠C = 180°

substituting m∠A = 35° and m∠C = 90° in the equation

35° + m∠B + 90° = 180°

125 + m∠B = 180°

subtract 125 from both sides

125 + m∠B - 125 = 180° - 125

m∠B = 55°

Thus, the measure of angle B is:

m∠B = 55°

As the exterior angle of the given triangle is adjacent to m∠B = 55°.

We know that the exterior angle of a triangle is equal to the sum of two opposite interior angles.

Here,

∠A and ∠C are two opposite interior angles of the exterior angle.

Thus,

The measure of an exterior angle is equal to the sum of two opposite interior angles.

as

m∠A = 35°

m∠C = 90°

so

Exterior angle = m∠A + m∠C

= 35° + 90°

= 125°

Thus, the measure of an exterior angle = 125°

Hence, option A is correct.

Ali buys pair of shoes for $18 the price is one fourth off the original price what decimal represents the discount?

jeyben [28]

The discount is one fourth, or 1/4 as a fraction.

To convert fraction to decimal, divide the numerator by the denominator.
1/4= 0.25

You can also convert to a fraction over 100, so that you can create a decimal down to the hundredths place value.
1/4= 25/100= 0.25

Final answer: 0.25

Appropriate Average. For each of the following distributions, decide whether you expect the mean, median, or mode to give the be

Genrish500 [490]

The average measures the expected value of a determined variable. Shows the "most likelly observation" of said distribution.

The median is a measure of center values that divides the sample in exact halves. When the distribution of the variable of interest is irregular or doesn't follow a determined pattern, it allows you to determine a basic distribution of the values.

The mode is the value or values with the most observed absolute frequency, this is, the value or values that are most repeated.

Examples

"Per capita earnings in New yourk City"

For this variable you could use the mode as a value of center tendency so that you will be able to determine the most frequent incomes or the mean, that will allow you to determine or predict the expected earnings.

23. "Number of times people change jobs during their carrers"

This variable doesn't have a determined distribution, meaning, there is not a natural variation in it, people changes jobs when the oportunity comes but it is relativelly random.

The best measure of center tendency for this variable will be the Median.

25. "The individual weights of oranges in a 5-pound bag"

The weight is characteristic that can be cassified as a continuous variable, these kind of variables have often a normal distribution or tend to it. The best measure of center for any continuous variable is the Mean.
