Answer:
The field will not fit
Step-by-step explanation:
To find the angle, we will use cosine rule;
c² = (a² + b² - 2abcosC)
C in this case is θ
Thus;
15² = (8² + 20² - 2(8 × 20)cos θ)
225 = (64 + 400 - 320cos θ)
464 - 225 = 320cos θ
cos θ = 239/320
θ = cos^(-1) 0.7469
θ = 41.68°
Thus angle is not less than 40° as recommended. Thus, the field will not fit.
Answer:

Step-by-step explanation:
we know that
The directrix of the parabola is perpendicular to the axis of symmetry of the parabola
In this problem the directrix is y=-3.5
so
The axis of symmetry is parallel to the y-axis
we have a vertical parabola
Also, the vertex is at the origin
That means-----> the parabola open upward
The equation of a vertical parabola can be written as

where
p is the distance between the vertex and the directrix
In this problem
the distance between the vertex and the directrix is 3.5
----> the value of p is positive because the parabola open upward
substitute


isolate the variable y

Answer: $195,000.00
Step-by-step explanation:
6/100 = 11700
100/100 = x
6/100(x)=11700
x = 11700 / (6/100)
= 11700 * 100/6
= 195000
X would equal 18 when y equals 12.
Since x equals 12 when y=8, you can write it as 8/12
Then it says when y = 12 what is x, well you divide 12 and 8 to get 1.5 then multiply 12 and 1.5 to get what x equals when y is equal to 12.
Correct me if I am wrong.
