Answer:

  • 50

Step-by-step explanation:

<u>Quantity 3 plus the square root of negative 16 end quantity:</u>

  • 3 + √-16

<u>Quantity 6 minus the square root of negative 64 end quantity:</u>

  • 6 - √-64

<u>Multiply the two above:</u>

  • (3 + √-16)(6 - √-64) =
  • (3 + 4√-1)(6 - 8√-1) =
  • (3 + 4i)(6 - 8i) =
  • 3*6 - 3*8i + 6*4i - 4i*8i =
  • 18 - 24i + 24i - 32i² =
  • 18 - 32(-1) =
  • 18 + 32 =

How do you solve this
Oliga [24]
First you have to do 27+35, which equals 62. Then you do x2, so 62x62= 3,844. The equation is x2= 27+35, x2= 3,844

Transform the quadratic function defined by y=ax2+bx+c into the form y=a(x-h)2+k 1.Y=x2-6x-3 2.Y=5x2-20x-5
Lana71 [14]

Answer:

<em>1) y = (x-3)²-12</em>

<em>2) y = 5(x-2)²-9 </em>

Step-by-step explanation:

Given the quadratic expressions

y=x²-6x-3

We are to transform it in the form y=ax²+bx+c

y=(x²-6x)-3

Complete the square of the expression in parenthesis

y = (x²-6x + (6/2)² - (6/2)²)-3

y = (x²-6x+3²-3²)-3

y = (x²-6x+9-9)-3

y = (x²-6x+9)-12

y = (x²-3x-3x+9)-12

y = x(x-3)-3(x-3)-12

y = (x-3)(x-3)-12

y = (x-3)²-12

Hence the transformation is y = (x-3)²-12 where a = 1 and k = -12

For the quadratic equation

y=(5x²-20x)-5

y = 5(x²-4x)- 5

Complete the square of the expression in parenthesis

y = 5(x²-4x+4-4)- 5

y = 5(x²-4x+4)-9

y = 5(x-2)²-9

<em>Hence the transformation is y = 5(x-2)²-9 where a = 5 and k = -9</em>

Given f(x) = x + 9 and g(x) = x2 find (gºf)(x).
marissa [1.9K]

Answer:

g(f(x)) = (x + 9)^2 or x^2 + 18x + 81

Step-by-step explanation:

(gºf)(x) is the "c .... " of two functions f(x) and g(x):  f(x) is the input to g(x).

We start with g(x):  g(x) = x^2.  We replace the first x with f(x) and the second x with x + 9:

g(f(x)) = (x + 9)^2 or x^2 + 18x + 81
