Answer:

y = \frac{1}{4} + (-2)

Step-by-step explanation:

Using the formula: y = mx + b

mx = slope

b = y intercept

y = \frac{1}{4} + (-2)

Here is what is will look like in a graph:

kvasek [131]

Answer:

12.0 to 3 dig digs You must include the 0 to get 3 significant figures.

Step-by-step explanation:

Comment

This is a Pythagorean Problem. Use the formula

c ^2 = a^2 + b^2

Givens

a = 8 - 7 = 1 cm

b = 12 cm

c = ?

solution

c^2 = 1^2 + 12^2  

c^2 = 1 + 144

c^2 = 145                 Take the square root of both sides

√c^2 = √145  

c = 12.04

c = 12.0 to 3 sig digs.

Answer:

  • The function is injective but nor surjective

Step-by-step explanation:

<u>We see that:</u>

  • f(x) = x³

<u>For any x₁ and x₂ ∈ N, </u>

  • f(x) = x₁³ = x₂³ ⇒ x₁ = x₂, both are natural numbers

It it confirmed one-to-one, hence it is injective

<u>Check the surjectivity:</u>

f(x) = y ∈ N

  • x³ = y
  • y = ∛x

<u>Let y = 2, then:</u>

  • 2 = x³
  • x = ∛2 ∉ N

Since x is not natural, the function is not surjective
