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

The perimeter of a square is 24 inches. Complete the equation and solve to find the length of each side, s.
Answer:
s = 6
Step-by-step explanation:
We know a square has all equal side lengths. So we would divide the square by four to get one side length.
24/4 = 6
s = 6
A parabola opening up or down has vertex (4, -1) and passes through (-9, -181/12). Write its equation in vertex form
Answer:
y = -1/12(x -4)² -1
Step-by-step explanation:
The vertex form equation for a parabola is ...
y = a(x -h)² +k . . . . . . vertex (h, k); vertical scale factor 'a'
The vertex coordinates are given. To find the scale factor, we substitute the given point.
-181/12 = a(-9 -4)² -1 . . . . . substitute the given values into the equation
-181/12 = 169a -1 . . . . simplify a bit
-169/12 = 169a . . . . add 1
a = -1/12 . . . . . . . multiply by 1/169
The vertex form equation of the parabola is ...
y = -1/12(x -4)² -1

Answer:
z= 23°
y= 120°
Step-by-step explanation:
For z, the measures of the angles are alternate interior angles, they equal each other. So, the equation would be:
66= 3z-3
Step 1- Add 3 to both sides.
66= 3z-3
+3 +3
69= 3z
Step 2- Divide both sides by 3.
69= 3z
3 3
z= 23°
For y, the measures of 66 and y are alternate exterior angles, they sum up to 180 degrees. So, the equation would be:
180= 60+y
Step 1- Subtract 60 to both sides.
180= 60+y
-60 -60
y= 120°

please help!! If y = sin x, then dy/dx =
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
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?
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%

Jaime has 636 blocks. About how many blocks does he have ?
a. 500
B.600
C.700
D.800
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:
We can easily tell that after rounding off, the number of blocks will be:
600Therefore, after rounding off Jaime has (B) 600 blocks with him.
