Answer:
Answer is option D) y=
Step-by-step explanation:
Quadratic graph with a focus and a directrix is a parabola as in the picture attached.
Now we assume a point (x,y) is given on the parabola.Focus of parabola be the point O(1,1) and the directrix y=(-1)
As we know that in a parabola distance OP is equal to the distance between P and directrix y=(-1)
Therefore OP = distance from directrix y = (-1)
=
Answer:
6 units
Step-by-step explanation:
The total area that the surface of a 3-dimensional object would cover if its sides were laid flat is called it's surface area. Surface area is measured in square units. The surface area of a unit cube is 6 square units.
Answer:
30
1.301
Step-by-step explanation
f(x) and g(x) are inverse functions. Note that the logrithmic notation for
So, when x = 1.477, f(x) = y = 30
and when x = 20, g(x) = y = 1.301
Answer:
For the code we have 3 selections.
The first selection is a digit that must be odd, so the options are {1, 3, 5, 7 ,9}
So we have 5 options.
The second selection is a letter from the set of all the letters (27) minus the set of the vowels (5)
So here we have 27 - 5 = 22 options
The third selection is also a letter from the previous set, but because each letter can be used only one time, and in the previous selection we already selected one of the letters, in this selection we have a letter less than in the previous selection.
Here we have 22 - 1 = 21 options.
The total number of combinations (of possible codes) is equal to the product of the number of options for each selection:
C = 5*22*21 = 2310.
There are 2310 different possible codes
Answer:
