(0,3), (4,15), (5,33), determine the equation of the parabola they represent. State the direction the parabola opens.
MakcuM [25]

Answer:

y = 3x² – 9b + 3 and the parabola opens upwards since a = 3 > 0.

Step-by-step explanation:

The general equation of a parabola is:

y = ax² + bx + c

So we have to solve for a, b and c to get our equation with the 3 given points.

When x = 0 and y = 3 we have

3 = a(0)² + b(0) + c, this means c = 3

When x = 4 and y = 15

15 = a(4)² + b(4) + 3 we have

16a + 4b = 12 which is

4a + b = 3

When x = 5 and y = 33 we have

33 = a(5)² + b(5) + 3 we have

25a + 5b = 30 which gives

5a + b = 6.

We have two equations

4a + b = 3

5a + b = 6

Eliminating b we have

a = 3, substituting a = 3 in the first equation we have

4(3) + b = 3

12 + b = 3

b = –9

Our equation therefore is:

y = 3x² – 9b + 3 and the parabola opens upwards since a = 3 > 0.

Which equation represents that relationship ??​
SpyIntel [72]

Answer:

A

Step-by-step explanation:

A proportional relationship either increases or decreases its points at the same rate. In the first set of ordered pairs, the x values all increase by 3 while the y values all increase by 6, which is twice the value of the x values' increasing. The second set of ordered pairs is not proportional because all pairs' x values increase by 2 while the y values increase by 8 until ordered pair (5, 20), so this set therefore is non-proportional. y = x + 3 is the correct equation because it represents that the y value is always 3 greater than the x value. All the shown ordered pairs for set 1 supports this (3 - 0 = 3, 6 - 3 = 3, 9 - 6 = 3, 12 - 9 = 3).

What is the polar form of -4+5i?
kifflom [539]

z= r(cosθ+i sinθ) is the required polar form where, r = √41 and θ =π- tan^{-1} (\frac{5}{4} )

Step-by-step explanation:

Given,

-4+5i is a complex number.

To find the polar form.

Formula

z=x+iy

r² = mod of (x²+y²)

θ = tan^{-1} (\frac{y}{x} )

So, the polar form will be z=r(cosθ+i sinθ)

Now,

r² =(-4)²+5² = 41

or, r = √41

θ =π- tan^{-1} (\frac{5}{4} ) [ since the point is in second quadrant]

Hence,

z= r(cosθ+i sinθ) is the required polar form where, r = √41 and θ =π- tan^{-1} (\frac{5}{4} )
