Answer:
Step-by-step explanation:
The diagram of the stadium and the blimp is shown in the attached photo. A right angle triangle, ABC is formed. Angle A is alternate to the angle of depression. This mean that they are equal. So angle A =40 degrees.
The distance of the the Blimp from the stadium is x feet which is the hypotenuse of the triangle.
Applying trigonometric ratio,
Sin 40 = 400/x
xsin40 = 400
x = 400/sin40 = 400 / 0.6428
x = 622.3 feet
27/36 = n/4
27*4 = 36n
108 = 36n
108/36 = 36n/36
n = 3
Answer:
probably 2 or 4
Step-by-step explanation:
Answer:
y = 3x –5
Step-by-step explanation:
for slope-intercept form, y = mx + b
find the slope, m
(-8 -4)/(-1-3) = m
-12/-4 =m
3 = m
Substitute for m and use either coordinate for y and x to calculate b
4 = 3(3) + b
4 = 9 + b. Subtract 9 from both sides
4 –9 = b
–5 = b. Rewrite the equation with the calculated values for m and b
y = 3x –5
Answer:
a) 0
b) 1
c) 0
Step-by-step explanation:
These are common values from the unit circle but you could also just check with your calculator. Just be sure to set it to degree mode and not radian mode.
