2r + 6 > -24
Hope that helps :)
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:
Explanation:
You can convert the percent markup into a multiplicative factor in this way:
Base price: 15,800 . . . (cost to the seller)
Percent mark up: 115% . . . (based on the cost to the seller)
Sale price: 15,800 + 115% of x = 15,800 + 115 × 15,800 /100 =
= 15,800 + 1.15 × 15,800 = 15,800 (2.15) = 33,970
The markup is:
- Markup = price paid by the seller - cost to the seller = 33,970 - 15,800 = 18,170 (notice that this is 115% of 15,800)
And <em>the percent markup based on the sale price is</em>:
- % = (markup / sale price) × 100 = (18,700 / 33,970) × 100 =
= 53.49 %
Rounding to the nearest tenth percent that is 53.5 %.
Answer:
-1, 0, 1, 2, 3
Step-by-step explanation:
All we need to do is substitute n for our first 5 terms:
a1 = 1 - 2 = -1
a2 = 2 - 2 = 0
a3 = 3 - 2 = 1
a4 = 4 - 2 = 2
a5 = 5 - 2 = 3
Answer:
Internal validity
Step-by-step explanation:
Internal validity is a scientific study that emphasize on the fact that there is a proof to validate a specific study. Let's say i'm a forensics scientist for example; and there was a recent crime scene in some nearby sub-urban area which demands our call, when present at the scene, The main task there is to gather information as much as we can which is required to be investigate in the laboratory for further analysis.The process of information gathering is our independent variables which varies with different causes of the crime, the laboratory analysis that make deductions (which is cause by some manipulation) of the information gathered is our dependent variables.
Therefore, we can conclude that Internal validity refers to the degree to which changes in the dependent variable are due to the manipulation of the independent variable.
