Answer:
Step-by-step explanation:
In the table, they give you an x-value. Use the x-value to solve for y. You will then get a point. Plot the points to find the graph.
y = 1/2x
y = 1/2(0)
y = 0
(0, 0)
y = 1/2x
y = 1/2(2)
y = 1
(2, 1)
y = 1/2x
y = 1/2(-4)
y = -2
(-4, -2)
63%
To express as a percentage divide 630 g by 1 Kg and multiply by 100%
note that 1 Kg = 1000 g ( units must be the same)
× 100% = 63%
Answer
As per the statement:
Height of the building(h)= 30 feet
Angle of elevation = 41°
We have to find the distance of observer from the base of the building.
Using tangent ratio:
You can see the diagram as shown below.
Opposite side = height of the building = 30 feet.
Adjacent side = distance of observer from the base of the building = x (let)
Then;
0.86928673781 =
By cross multiply we have;
Divide by 0.86928673781 both sides we get;
x = 34.51 m
Therefore, the distance of observer from the base of the building is 34.51 m
