Answer:
The answer is below
Step-by-step explanation:
Select the quadrant in which the terminal side of the angle falls.
210° terminates in quadrant
-150° terminates in quadrant
390° terminates in quadrant
Solution:
The x and y axis divides the cartesian plane into four equal parts known as the four quadrants.
Angles between 0° and 90° are in the first quadrant, angles between 90° and 180° are in the second quadrant, angles between 180° and 270° are in the third quadrant while angles between 270° and 360° are in the fourth quadrant.
a) Since 210 degrees is between 180° and 270°, hence it terminates in the third quadrant.
b) -150° = 360 - 150 = 210°. Since 210 degrees is between 180° and 270°, hence it terminates in the third quadrant.
c) 390° = 390° - 360° = 30°.
Since 30 degrees is between 0° and 90°, hence it terminates in the first quadrant.
Answer:
-9
Step-by-step explanation:
f(2) - f(4) / 2-4
[2²+3(2)] - [4²+3(4)] / -2
(10 - 28) / 2
= -18/2
= -9
Answer
The answer to your question is 2 x 2 x 5 x 5 or 2² 5²
Step-by-step explanation:
Process
1.- To find the prime factors of a number, we must divide the number by prime numbers like 2, 3, 5, 7, 11, etc. starting from the lowest number.
100 2
50 2
25 5
5 5
1
Then 100 = 2 x 2 x 5 x 5 or 2² 5²
It can be expressed as a fraction with integer numerator and denominator, so it's a rational number.
Z = (x - mu)/sigma
z = (6.19 - 3.77)/3.39
z = 0.71386430678467
z = 0.71
The approximate z score, rounded to two decimal places, is 0.71
