Answer:

D

Step-by-step explanation:

Since Θ is in the fourth quadrant where cosΘ > 0

The only positive values are B / D

since 0 < cosΘ < 1

\frac{\sqrt{41} }{5} > 1 then

D is the appropriate response

Meg found one treasure at − 3 4 foot. Which of these location are higher than − 3 4 foot? Check all that apply. Negative StartFr
Neporo4naja [7]

Answer:

\frac{-1}{4}and \frac{-5}{8} are the locations higher than \frac{-3}{4} foot

Step-by-step explanation:

We are given that Meg found one treasure at \frac{-3}{4}foot

We are supposed to find Which of these location are higher than \frac{-3}{4}foot?

i) -\frac{7}{8}

So, this location is not  higher than \frac{-3}{4}foot

ii)-\frac{1}{4}

So, -\frac{1}{4}>\frac{-3}{4}

So, this location is higher than\frac{-3}{4} foot

iii) - 1 foot

-1 < \frac{-3}{4}

So,this location is not  higher than\frac{-3}{4}foot

iv)-2 feet

So,this location is not  higher than\frac{-3}{4}foot

v)\frac{-5}{8}

So, this location is higher than \frac{-3}{4}foot

The linear inequality y&lt;-2/3x+2 is graphed. Determine a solution for the inequality. A) (0,2) B) (3,0) C) (0,0) D) (0,3)
jenyasd209 [6]

Hello!

The graph y < -2/3x + 2 has a dotted line. That means that any points on the dotted line or not shaded, is not a solution to this inequality. Since we are given 4 choices, we can substitute those values into the given inequality to see if it is true.

A) (0, 2)

2 < -2/3(0) + 2

2 < 2, this is false.

B) (3, 0)

0 < -2/3(3) + 2

0 < -2 + 2

0 < 0, this is false.

C) (0, 0)

0 < -2/3(0) + 2

0 < 2, this is true.

D). (0, 3)

3 < -2/3(0) + 2

3 < 2, this is false.

To check if choice C) (0, 0) is true, we should look at the given graph.

Since (0, 0) is in the shaded area, and is not graphed on the dotted line, therefore, a solution to this linear inequality is C, (0, 0).
