Answer:
Sine is an odd function and presents positive values in the 1st and 2nd quadrants and negative values in the 3rd and 4th quadrants.
Step-by-step explanation:
-sin(x) = sin(-x)
This property is valid because the sine trigonometric function presents positive values in the first two quadrants and negative values in the third and fourth quadrants. The sine function is an odd function with symmetry with respect to the origin, which means that sin(x) and sin(-x) will always present opposite signs.
Answer:
A : ±2
Step-by-step explanation:
Add 14 and you have ...
... x² = 4
Take the square root and you have ...
... x = ±√4 = ±2
24
It goes into 24 once and into 48 twice
Answer:
132 in
Step-by-step explanation:
rectangle- 12(8)=96
triangle 1- 3(12)= 36 divide by 2 = 18
triangle 2- same as tri. 1
rapeziod- 96+18+18=132
1.8 km >> 1,800 m
1,800 - 740 = 1,060 m
1,060 m >> 1.06 km
The shorter route is 1.06 km.
