Answer:
Getting the right answer
Step-by-step explanation:
It really depends on what the teacher says but it's more important for you to understand the actual process, else you wouldn't be able to get the answers if you don't understand the process.
Answer:
36/4
y would be 9 when x is 11
Answer:
91.8 ft
Step-by-step explanation:
So we can talk about the diagram, let's name a couple of points. The base of the tree is point T, and the top of the tree is point H. We want to find the length of TH given the length AB and the angles HAT and ABT.
The tangent function is useful here. By its definition, we know that ...
TA/BA = tan(∠ABT)
and
TH/TA = tan(∠HAT)
Then we can solve for TH by substituting for TA. From the first equation, ...
TA = BA·tan(∠ABT)
From the second equation, ...
TH = TA·tan(∠HAT) = (BA·tan(∠ABT))·tan(∠HAT)
Filling in the values, we get ...
TH = (24.8 ft)tan(87.3°)tan(9.9°) ≈ 91.8 ft
The height <em>h</em> of the tree is about 91.8 ft.
The equation of a line parallel to the y-axis is is the equation of a vertical line since the vertical line lies along the y-axis. The equation that represents a line which is parallel to the y-axis is x = -8
<h3>Equation of a line</h3>
A line is defined as the shortest distance between two points. The formula for finding the equation of a line in slope-intercept form is given as;
y = mx + b
The point sloe form of the equation is given as y-y1 = m(x-x1)
where
- m is the slope
- b is the intercept
- (x1, y1) is any point on the line
The equation of a line parallel to the y-axis is is the equation of a vertical line since the vertical line lies along the y-axis.
The equation of a vertical line is expressed in the form x = a where a is the x-intercept.
Therefore the equation that represents a line which is parallel to the y-axis is x = -8
