Answer 1

Answer: 1) 20-2e
3)12f+32f^2+14f^4

Answer 2

Answer: like terms are a number that have the same variable (ex. a, b, etc.) and the same exponent. on number one, 11 & 9 are like terms so 11+9=20. number one is 20-2e

A pole that is 3.4m tall casts a shadow that is 1.03m long. At the same time, a nearby building casts a shadow that is 41.5mlong. How tall is the building?

Answers

I got that the building is 136.9902912...(nonterminating) meters tall. Or you could round that to 137m tall. I got that by setting up ratios of the height and the shadows, then cross multiplying.

The first is not a solution, but the second is.

B.
Both are solutions.

C.
The first is a solution, but the second is not.

D.
Neither is a solution.

Answers

b.

if you plug in the points you get for the first one
3(3) - (4/(-8)) = 9+2 = 11
and the second
3(4) - (4/4) = 12-1 = 11

Draw a 30° angle in standard position on the coordinate plane. Show the direction of rotation. Label the terminal side and the angle measure.

Answers

also the direction is anti clockwise

I hope it could help you :)

Final answer:

To draw a 30° angle in standard position on the coordinate plane, start by drawing the initial side of the angle which is the positive x-axis. Use a protractor to measure a 30° angle counterclockwise from the initial side. Then draw a line from the origin to the endpoint of the angle to represent the terminal side. Label the angle measure as 30° and label the terminal side accordingly. Indicate the direction of rotation by drawing an arrow showing the counterclockwise direction.

Explanation:

To draw a 30° angle in standard position on the coordinate plane, follow these steps:

Start by drawing the initial side of the angle, which is the positive x-axis.
Using a protractor, measure a 30° angle counterclockwise from the initial side.
Draw a line from the origin to the endpoint of the angle to represent the terminal side.
Label the angle measure as 30° and label the terminal side accordingly.
Indicate the direction of rotation by drawing an arrow showing the counterclockwise direction.
