Answer:
B -⅓
Step-by-step explanation:
sinx = -3/5
Adjacent² = 5² - 3² = 16
Adjacent = 4
tan(x) = -3/4
-¾ = 2tan(½x)/[1 - tan²(½x)]
-3 + 3tan²(½x) = 8tan(½x)
3tan²(½x) - 8tan(½x) - 3 = 0
tan(½x) = 3, -⅓
Answer:
1 solution
Step-by-step explanation:
If you were to graph this line it would be a straight line so there is 1 solution.
y=3x
x=y/3
Answer:
Area of the rectangle = 144 square inches
Step-by-step explanation:
Area of a rectangle = length × width
Width = 4 inches
Length = 3 feet
1 feet = 12 inches
3 feet = 36 inches
Area of a rectangle = length × width
= 36 inches × 4 inches
= 144 square inches
Therefore,
Area of the rectangle = 144 square inches
Solution:
<u>Note that:</u>
- Slope = m = 4
- Given point: (x₁,y₁) = (1,1) [x₁ = 1; y₁ = 1]
- Formula: y - y₁ = m(x - x₁)
<u>Use the formula to convert the line in point slope form.</u>
- y - y₁ = m(x - x₁)
- y - 1 = 4(x - 1)
The equation of the line (In point slope form) is y - 1 = 4(x - 1).
