Answer: The first answer choice

Step-by-step explanation:

In the first answer choice, the distance increases for two units, then decreases for three units. The distance then increased for 4 units, stayed level for 3 units, and then decrease slowly for 6 units. The graph exactly follows this trend.

The second answer is <em>immediately wrong</em> because it relates the distance between the car and the concert venue. <em>It never mentioned that the car moved, and the venue obviously can't move</em>.

The third answer says that after the first increase/decrease, Tyler went to go text his friends. However, <em>the graph does not show a flat area after the first increase/decrease</em>.

The fourth answer, like the second answer is immediately wrong because <em>homes and schools can't move</em>.

This is my first response, so I hope it was helpful. :D

Helpp!!!<br> prove that:<br> cosecA-cotA= tanA/2
romanna [79]

Answer:

tanA/2.

Step-by-step explanation:

some trigonometric properties:

* tanA = sinA/cosA

* secA = 1/cosA

* cscA = 1/sinA

* cotA = cosA/sinA

1/sinA - cotA

1/sinA - cosA/sinA

1 - cosA / sinA

.... 1 - cosR / sinR = tan(R/2)

1 - cosA / sinA

= tanA/2.

A circular garden has a diameter of 6 feet. Which of the following is closest to the area of the garden?
oksian1 [2.3K]
The answer to this problem is 'B'.

This is because to find the area of a circle your formula is
A = 3.14•r²
So your first step is

1. Find the radius by dividing the diameter (6) by 2
6/2 = 3 Radius= 3

Now that you have found the radius (3) plug the number in the formula
2. A = 3.14•3²
OR
A = 3.14•3•3

Finally, solve the last step - Find the area
3.14 • 3 • 3 = 28.26
A = 28.26
