Answer:

3.8*10^1

Step-by-step explanation:

So we'll be using PEMDAS, which is an acronym used to explain order of operations. It stands for P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction.

P- Parentheses:

(2x3+4x2+3)+(3x3−(3x−4))

M- Multiplication (within Parentheses):

(6+8+3)+(9−(-12))

A- Addition (within Parentheses):

(6+8+3)+(9−(-12))

17 + 21

A- Addition:

38

Now, we'll take that number and put it in standard form, which is the number with only one number outside of the decimal times ten to the however many times it can be divided by ten.

So,

38/10 = 3.8

So,

3.8 * 10^1 is your answer.

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

Step-by-step explanation:

These 2 angels are alternate interior angles so they are equal

5x-18=3x+42

Solve.

2x=60

x=30

Now substitute x into angle A

A=150-18

A=132
