Please solve this problem because tomorrow is my exam.<br><br>

jonny [76]

Step-by-step explanation:

a). A = {x ∈ R I 5x-8 < 7}

5x - 8 < 7 <=> 5x < 8+7 <=> 5x < 15 =>

x < 3 => A = (-∞ ; 3)

A ∩ N = {0 ; 1 ; 2}

A - N* = (-∞ ; 3) - {1 ; 2}

b). A = { x ∈ R I 7x+2 ≤ 9}

7x+2 ≤ 9 <=> 7x ≤ 7 => x ≤ 1 => x ∈ (-∞ ; 1]

A ∩ N = {0 ; 1}

A-N* = (-∞ ; 1)

c). A = { x ∈ R I I 2x-1 I < 5}

I 2x-1 I < 5 <=> -5 ≤ 2x-1 ≤ 5 <=>

-4 ≤ 2x ≤ 6 <=> -2 ≤ x ≤ 3 => x ∈ [-2 ; 3]

A ∩ N = {0 ; 1 ; 2 ; 3}

A - N* = [-2 ; 3) - {1 ; 2}

d). A = {x ∈ R I I 6-3x I ≤ 9}

I 6-3x I ≤ 9 <=> -9 ≤ 6-3x ≤ 9 <=>

-15 ≤ -3x ≤ 3 <=> -5 ≤ -x ≤ 3 =>

-3 ≤ x ≤ 5 => x ∈ [-3 ; 5]

A ∩ N = {0 ; 1 ; 2 ; 3 ; 4 ; 5}

A - N* = [-3 ; 5) - {1 ; 2 ; 3 ; 4}

Either my brain is straight up goneskiis or I need assistance.

olga nikolaevna [1]

The answer is C. 89 in^2

This is found by (1/2( $\pi r^{2}$ ))+70

r in this equation stands for radius which is half the diameter. Sice the diameter equals 7, the radius equals 3.5

You have to solve this by putting it into a calculator since you can't really solve for an equation with pi in it otherwise.

Hope this helps!

A soccer ball is kicked and travels 25 meters to the north in 2.5 seconds. At what velocity is the ball traveling?

algol [13]

It would be 10m.
If you divide 25 by 2.5 you get 10, and since we’re using velocity, that’s what we would do.
