jonny [76]3 years ago

Answer:

y = 5 ( x - 3 ) ^2 -2

OR

y+2= 5 ( x - 3 ) ^2

Step-by-step explanation:

Vertex form of a parabola is given as:

y = a ( x - h ) ^2 + k

Where (h,k) is the vertex and (x,y) are the points on the parabola.

We are given that, the vertex is (3, -2) and another point on parabola is given as (2, 3).

h = 3,k = -2

First of all, putting the vertex in the vertex equation as given above:

y = a ( x - 3 ) ^2 + (-2)

Now, putting the values of x, y as 2, 3 and let us find the unknown variable a:

3 = a ( 2 - 3 ) ^2 + (-2)\\\Rightarrow 3 = a -2\\\Rightarrow a = 5

Therefore, the equation in vertex form can be written as:

y = 5 ( x - 3 ) ^2 -2

OR

y+2= 5 ( x - 3 ) ^2

6. For what value of p, the binary number 110P/2 represents 25?​
lions [1.4K]

Step-by-step explanation:

25 as binary number is

11001

1×2⁴ + 1×2³ + 0×2² + 0×2¹ + 1×2⁰ = 16 + 8 + 1 = 25

25×2 = 50 = 11001 × 2 = 110010

multiplying a binary number by 2 is the save effect as multiplying a normal decimal number by 10 : all digits move one position to the left, and a 0 is put into the empty right position.

and so, we see

110P = 110010

P = 010

FYI : you normally don't mix binary and decimal numbers. if one of the numbers is binary, then all the others have to be binary too.

so, the problem should have looked like

110P/10 = 11001

110P = 11001×10 = 110010

P = 010
