Answer:
The answers are A, E and F because the amount Darren's friend adds to his savings each week is a faster rate or higher amount than $40 dollars:
y = 75x(higher than 40) + 120
y = 120 + 50x(higher than 40)
y = 87x(higher than 40) + 120
Answer:
6.519801752°
Step-by-step explanation:
Let θ represent the angle of depression
tanθ=40/350
θ=tan^-1(40/350) *tan^-1 means inverse tan*
θ=6.519801752°
Answer:
68 cm
Step-by-step explanation:
√289 = 17
each side is 17 cm
17 * 4 = 68 cm
The length of the sky lift is 3.387.05 ft
Step-by-step explanation;
By an online search, i found that the sky lift
rises at an angle of 20.75 degrees.
Then we can think on a triangle rectangle, such
that:
One cathetus is 1200ft, this is the opposite
cathetus to the angle of 20.75°
The length of the ski lift would be the
hypotenuse of this triangle rectangle.
Then we can use the relationship:
Sin(a) = opposite cathetus/hypoteuse.
such that:
a = 20.75°
opposite cathetus=1200ft
then:
sin(20.75°) = 1200ft/hypotenuse
hypotenuse =1200ft/sin(20.759) =3.387.05 ft
The length of the sky lift is 3.387.05 ft
