Answer:
x-less than-or-equal-to 3
Step-by-step explanation:
4x + 6 < 18 (less than or equal to)
4x < 12 (less than or equal to) x < 3 (less than or equal to)
Simply use the formula they give you. For question 6, 4 is the radius. So the area of the circle is 4pi. Now for seven you do the same thing, but they gave you the diameter instead and it’s a half circle. So try that one on your own. Let me know if you get stuck
Answer: True
Step-by-step explanation:
We try to keep the number greater than 1 and lower than 10, so between 1, and 9.
For example: 3545346 would be 3.5x10^6
you can see 3.5 is between 1 and 9
Answer:
The answer to your question is the second choice tan Ф = -3/4
Step-by-step explanation:
Data
sin Ф = -3/5
cos Ф > 0
Process
1.- The sin Ф is negative, which means that is in the third or fourth quadrant.
2.- sin Ф = -3/5 and sin Ф = Opposite side/hypotenuse
then, Opposite side = 3 hypotenuse = 5
3.- Calculate the adjacent side using the Pythagorean theorem
c² = a² + b²
b² = c² - a²
b² = 25 - 9
b² = 16
b = 4
4.- If cos Ф is in the third quadrant
cos Ф = -4/5 and cos Ф < 0 This is incorrect
5.- If cos Ф is in the fourth quadrant
cos Ф = 4/5 and cos Ф > 0 This is correct
Then, this angle is in the fourth quadrant
6.- Calculate tan Ф
tan Ф = -3/4
