The slope-intercept form of the equation for a line with a slope of -4 and a y-intercept of -2 is ...
y = -4x -2
Answer:
128.67 feet
Step-by-step explanation:
We would be solving this question using the Trigonometric function of tan.
Tan( of the angle of elevation) = height of the tower ÷ height of the shadow.
Angle of elevation = 65°
Height of the tower = unknown, which is designated as X
Height of the shadow = 60 feet.
Therefore,
tan 65° = X/ 60 feet
We crossmultiply
X = tan 65° × 60 feet
X = 128.67041523 feet.
Approximately, X = 128.67 feet.
Therefore, the tower is 128.67 feet tall.
Answer: Again I ask.... What?
Step-by-step explanation:
Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
If lines are parallel then they have the same slope (m)
This means that the slope of the line will be 3
y = 3x + b
Now we must find b
To do that you must plug in the point the line goes through in the x and y of the equation.
(5, 2)
2 = 3(5) + b
2 = 15 + b
-13 = b
y = 3x - 13
