Identify which quadrant contains the terminal side of an angle in standard position with each given degree measure. 75° 120° –30° –200°.

Answers

Answer:

75° quadrant 1

120° quadrant 2

-30° quadrant 4

-200° quadrant 2

The measure 75° is in Quadrant I, 120° is in Quadrant II, -30° is in Quadrant IV and -200° is in Quadrant III.

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Angles in standard position are measured in a counterclockwise direction from the positive x-axis.

An angle of 75° is less than 90° and lies between the positive x-axis and the positive y-axis, so it is in Quadrant I.

An angle of 120° is greater than 90° and less than 180°, so it is between the positive y-axis and the negative x-axis, which means it is in Quadrant II.

An angle of -30° is equivalent to a 330° angle (360° - 30°) and lies in Quadrant IV because it is less than 360° and greater than 270°.

An angle of -200° is equivalent to a 160° angle (360° - 200°) and lies in Quadrant III because it is greater than 90° and less than 180°.

Hence, the measure 75° is in Quadrant I, 120° is in Quadrant II, -30° is in Quadrant IV and -200° is in Quadrant III.

a. 500

B.600

C.700

D.800

Answers

Answer:

B.) 600

Step-by-step explanation:

if you are rounding to the nearest hundred value you would get 600 because the 3 in 638 will round down to 600

it can not be A because it is to far down from the number line

it can not be C or D because they are to far up on the number line

So the correct answer has to be B-600

if the 2nd number is 5 or more you will always round up.

if the 2nd number is 4 or less you will have to round down.

After rounding off Jaime has (B) 600 blocks with him.

What is rounding off?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done. The crucial figures are preserved when numbers are rounded off. to reduce the number of significant digits in a number to an approximate value. Round off the numbers 15.4 to 15, 15.51 to 15.5 or 16, 0.499 to 0, and 970,000 to 1 million.

So, rounding off 636:

A parabola opening up or down has vertex (4, -1) and passes through (-9, -181/12). Write its equation in vertex form

The vertex coordinates are given. To find the scale factor, we substitute the given point.

A bag contains 6 red, 5 yellow, and 3 black marbles. You select one
marble at random. What is the probability that it is a red or black
marble?

Answers

Answer:

The probability that it is a red or black marble is 0.6429, or 64.29%

Step-by-step explanation:

Frequentist Probability

The probability of an outcome is defined as the frequency of the number of ways the outcome occurs relative to the number of ways that it could have occurred.

The equation to calculate the probability is:

[tex]\displaystyle P(A)=\frac{m}{n}[/tex]

Where m is the number of ways the event A can occur and n is the total number of ways it could have occurred.

The bag contains 6 red, 5 yellow, and 3 black marbles. If one of them is randomly selected, it can be of any color from a total of n=6+5+3=14

Event A consists of the marble being red or black. It can be taken from m=6+3=9 marbles.

The probability is:

[tex]\displaystyle P(A)=\frac{9}{14}=0.6429[/tex]

The probability that it is a red or black marble is 0.6429, or 64.29%

Answers

Answer:

the answer is option B

Step-by-step explanation:

To find dy/dx the equation here is

first multipled by derivative of second + second multipled by derivative of first

y = x*sinx

dy/dx = x * derivative of sinx + sinx * derivative of x

derivative of x with respect to x is 1

derivative of sinx with respect to x is cosx

therefore

dy/dx = x * cosx + sinx * 1

= x * cosx + sinx

Which of the following inverse operations do you perform on the multiplication equation 3x=−27 to isolate the variable?
A.Divide by 3 on both sides of the equation
B.Multiply by 3 on both sides of the equation
C.Add 3 to both sides of the equation
D.Subtract 3 from both sides of the equation

Answers

The answer is A because you would have to divide. In this equation, we are doing multiplication so we have to do the inverse operation which would be division. We are trying to get x by itself so we would have to divide each side by 3. If you do that to each side, the left side would be left as just x, and the right side of the equation would be -9 because -27 divided by 3 would equal -9. Hope this helps!
