1. 8 = 8 => refrexive

2. If x = y, then y = x => symmetric

3. If x = y and y = 7, then x = 7 => transitive

4. 6 + 2 = 2 + 6 => commutative - addition

5. 5 ∙ 2 = 2 ∙ 5 => commutative - multiplication

6. 10 + (3 + 2) = (10 + 3) + 2 => associative - addition

7. 6(3 ∙ 5) = (6 ∙ 3)5 => associative - multiplication

8. 4(8 + 1) = 4 ∙ 8 + 4 ∙ 1 => distributive

9. 6 + 0 = 6 => identity - addition

10. 8 ∙ 1 = 8 => identity - multiplication

11. 1/2 ∙ 2 = 1 => multiplicative inverse

12. 5 ∙ 0 = 0 => property of zero

The graph of f ′ (x), the derivative of f of x, is continuous for all x and consists of five line segments as shown below. Given

ivolga24 [154]

Answer:

Step-by-step explanation:

f(0) - f(-3) = area under f'(x) from x=0 to x=3.

We can find the area under f'(x) in this interval by finding the area of the triangle formed by the line.

A = 1/2 b h

A = 1/2 (3) (3)

A = 4.5

f(0) - f(-3) = 4.5

Since f(0) = 7:

7 - f(-3) = 4.5

f(-3) = 7 - 4.5

f(-3) = 2.5

No. 1 = x
No. 2 = 2x+7
No. 3 = x-12

Answer:

x+(2x+7)+(x-12) = 131

From there you solve to get the numbers:

Hey guys! Leave the answer in terms of pi :)

DaniilM [7]

A) if the diameter is 13 the radius is 6.5
$(6.5 \times 6.5) \times \pi = 42.25\pi \\ = 132.7323$
b)if the diameter is 6 the radius will be 3
$(3 \times 3) \times \pi = 9\pi \\ = 28.27433$
hope this helps

Guys please answer question C i need it

chubhunter [2.5K]

Answer:

see below

Step-by-step explanation:

Except for the stretch factor, your work is completely correct. Multiplying only the x-coordinate by a factor of 2 results in a horizontal stretch by that factor.

Your coordinates and graph are correct.

In the comparison, you just need to say what happened.
