Answer:

A = 1

B = 2

C = below

Step-by-step explanation:

Zero is included in the second interval, therefore, A = 1 is a correct choice (A must be also less than 2 ).

B must be positive, so that, f(0) is above the x-axis, therefore, B = 2 is a correct choice.

f(1.5) is negative, this means that the function is below the x-axis, then, C = below.

For which inequality would x = 8 not be a solution?4x + 3 > 09x - 5 < 100x + 4 ≤ 1072 ÷ x ≥ 4

galina1969 [7]

Given:

Given the inequalities:4

$\begin{gathered} 4x+3>0 \\ 9x-5$

Required: Identify the inequality in which x = 8 is a solution.

Explanation:

Substitute 8 for x in each inequality and check whether it satisfies the inequality.

Consider 4x + 3 > 0.

$4\cdot8+3=35>0$

So, x = 8 satisfies the inequality 4x + 3 > 0.

Consider 9x - 5 < 100.

$9\cdot8-5=67$

So, x = 8 satisfies the inequality 9x - 5 < 100.

Consider x + 4 ≤ 10.

$8+4=12>10$

So, x = 8 not satisfies the inequality.

Consider 72 ÷ x ≥ 4.

$72\div8=9\ge4$

So, x = 8 satisfies the inequality.

Final Answer: The inequality in which x = 8 is not a solution is x + 4 ≤ 10.

Find the circumference a circle with the diameter AB A (-8,4) and B (4,-1)

Simora [160]

Answer:

C = 13π ≈ 40.82 units

Step-by-step explanation:

C = 2 r π = d π

AB = $\sqrt{(-8-4)^2 +(4+1)^2}$ = 13 units

C = 13π ≈ 40.82 units ( π ≈ 3.14 )

What is the reference angle for a 240 degree angle?

Veronika [31]

The reference angle for 240° is 60° because 240 is in quadrant III. If you were to subtract 240 from 180 you’d get 60.
