Answer:
y-4=(-1/2)(x-4)
Step-by-step explanation:
Slope=(8-4)/(-4-4)=-4/8=-1/2
The equation of the line is y-4=(-1/2)(x-4)
Answer:
c=2(3.14)r
given c=14(3.14), then r
make r the subject formula and substitute given c=14(3.14)
r=c/2(3.14)
r=14(3.14)/2(3.14)
r=7
Step-by-step explanation:
Answer:
length of scale drawing = 9 feet
width of scale drawing = 3 feet
Step-by-step explanation:
Actual dimension 15 feet by 45 feet.
length = 45 feet
width = 15 feet
Dimension on drawing is 20% of actual dimension.
20% = 20/100
Thus,
20% of 15 feet = 20/100 * 15 feet = 3 feet
20% of 45 feet = 20/100 * 45 feet = 9 feet
Thus, length of scale drawing = 9 feet
width of scale drawing = 3 feet

Answer:
x ≈ 23.4
Step-by-step explanation:
You are correct that the given information indicates the tangent function is appropriate.
Tan = Opposite/Adjacent
tan(59°) = 39/x
Multiply this equation by x/tan(59°) and you get ...
x = 39/tan(59°)
x ≈ 39/1.6643 ≈ 23.43
The appropriate answer choice is ...
x = 23.4
