Approximately how many times greater is 2.3x10^-4 than 1.15x10^-8 ?
Minchanka [31]

Answer:

2.3 × 10^{-4} is 20,000 times greater than 1.15 × 10^{-8}

Step-by-step explanation:

Given as :

The first number= x = 2.3 × 10^{-4}

The second number= y = 1.15 × 10^{-8}

Let The first number is z times greater than second number

i.e x = z × y

Or, z = \dfrac{x}{y}

Or, z = \dfrac{2.3\times 10^{-4}}{1.15\times 10^{-8}}

Or, z = 2 × 10^{4}

∴  z = 20,000

So,The first number is 20,000 times greater than second number

Hence, 2.3 × 10^{-4} is 20,000 times greater than 1.15 × 10^{-8} . Answer

What is the vertex of the quadratic function fix=(x-8)(x-2)
VikaD [51]

Answer:

Vertex: (5, -9)

Step-by-step explanation:

fix = (x-8)(x-2)

fix = x^2 - 2x - 8x + 16

fix = x^2 - 10x + 16

a = 1, b = -10, and c = 16

To find vertex:

x = -b/2a

x = -(-10)/2(1)

x = 10/2

x = 5

y = 5^2 - 10(5) + 16

y = 25 -50 + 16

y = -9

Vertex: (5, -9)
