Answer:
1. True
2. True
3. y = -1
4. False
Step-by-step explanation:
1 -------------------------
sin(-90) = -1
sin(270) = -1
True
2 --------------------------
y = cos(-90)
y = 0
True
3 -------------------------
y = tan(-45)
y = -1
-1
4 ---------------------------
tan(90) cannot be calculated
False
Answer
4+21m
Explanation
Use the distributive property 4 times 1 and 4 times 7m keep the m
The answer would be an obtuse scalene triangle.
Answer:
5.83 miles
Step-by-step explanation:
Bill's net distance west of his starting point is -4+7 = 3 miles. His net distance north of his starting point is 5 miles. The straight-line distance will be the hypotenuse of a right triangle with legs 3 miles and 5 miles. That distance is given by the Pythagorean theorem:
d² = (3 mi)² +(5 mi)² = 34 mi²
d = √34 mi ≈ 5.83 mi
Bill is 5.83 miles on a direct line from his starting point.
_____
The attached calculator screenshot shows the sum of the travel distances. The angles are bearings measured clockwise from north. The angle of the sum indicates Bill is about 31° west of north relative to his starting point.
