Answer: x ≈ 18 ft
Step-by-step explanation:
We will use our trig knowledge to solve this.
The man is standing 10 ft away, but we also need to add the 5 ft shadow as well as that is a point on our triangle.
We can set up a simple trig equation of: tan(50) = x/15
x being the height of the lamppost.
Now we solve.
tan(50) = 1.1918
1.1918 *15 = x
x = 17.876
Now round to the nearest foot.
x ≈ 18 ft
Hey there!!
Domain - all the x values
Domain for this is
-6 < x ≤ 2
Interval notation = ( -6 , 2 ]
as one of the dots is not filled and for the domain we will always have to got from the left to right
Hope my answer helps!
Answer:
Square
Step-by-step explanation:
You can use the distance formula from one point to another to find that the side lengths are all equals.
You can also graph it and see that it is a triangle.
Answer:
2nd graph (in the attached pics)
Step-by-step explanation:
Graphically, the <em>x-intercepts of the graph of a quadratic function are its zeroes. </em>
There can be
- no zeroes (where graph doesn't cut the x-axis at all),
- 1 zero (where graph touches the x-axis at one point only), and
- 2 zeros (where the graph cuts the x-axis at 2 points)
Looking at the figures, the 2nd graph has no real zeroes, <em>because the graph doesn't cut the x-axis at all!</em>
<em />
So, the answer is the second graph.
Answer:
major arc CEB = 320°
Step-by-step explanation:
arc BF = 140°
arc CE = 140°
arc CB = arc EF
arc CB + arc EF = 360-280 = 80
arc CB = 40°
major arc CEB = 360 - 40= 320°
