so h = 7, k = -2, meaning the vertex is at (7, -2).
the squared variable is the "y", meaning is a horizontal parabola.
the "p" distance is negative, for a horizontal parabola that means, it's opening towards the left-hand-side.
we know the focus and directrix are "p" units away from the vertex, and we know the parabola is opening horizontally towards the left-hand-side.
the focus is towards it opens 1 unit away, at (6, -2).
the directrix is on the opposite direction, 1 unit away, at (8, -2), namely x = 8.
Answer:
option d is correct none of the above
(4*3)+-4=8, this is just how to put it in the equation
Answer:
1:2:5
8
Step-by-step explanation:
Here is the full question :
n a managed forest, three different trees are planted. The trees are beech, holly and maple.
For every beech tree planted, there are 2 holly trees planted and 5 maple trees planted.
(a) Write down the ratio of trees.
b) If 40 maple trees were planted, how many beech trees would be planted?
the ratio of beech to holly to maple = 1 : 2 : 5
number of maple trees planted =( ratio of maple trees / sum of ratios ) x total number of trees
sum of ratios = 1 + 2 + 5 = 8
let a = total number of trees planted
( 5/8 ) x a = 40
a = 64
total number of beech planted = (1 / 8 ) x 64 = 8
For this case, the first thing to do is to graph the ordered pairs given in the problem.
Then, join the points to see the quadrilateral formed.
In this case the quadrilateral is a trapezoid.
The trapezoid is a geometric figure with four sides, of which only two are parallel.
Answer:
trapezoid
