Mathematics

Answer:

Read below for each answer! (^-^)

Step-by-step explanation:

1: You got the first one right. The explanation does explain why but think about 0 as the surface of the water to better understand.

2: -3; it is between 2 and 4 with only one line through it meaning that it is -3.

3: 7. That's the greatest number both can divide into it.

4: The last one. Any positive number is greater than a negative one and peanut butter's freezing point is positive while the other one's is not.

5: You got it right again! -(-1) has two negatives. Two negatives (mostly) make a positive. So positive 1! Now describe that on a number line.

Hope this helps!

Sin theta=-1/2 then cos theta=​
zepelin [54]

Answer:

<h2>cos 30°= 0.866</h2>

Step-by-step explanation:

Step one:

Applying the SOH CAH TOA principle

assuming all dimensions are in cm

Step two:

Given data

opposite= 1 cm

hypotenuse= 2 cm

<h3>we can now solve for θ</h3>

Sin(θ)= opp/hyp

Sin(θ)= 1/2

Sin(θ)= 0.5

θ= sin-1 0.5

θ= 30°

hence  from tables cos 30°= 0.866

Someone help me please
vladimir1956 [14]

Step-by-step explanation:

Hi,

You will have to move the pre-image 15 units to the right. You're also going to have to flip the image horizontally (kind of like flipping it across the x-axis) and after that, you're going to have to flip it so that it's facing the left side.

1) 15 units right

2) Flip-up

3) Flip to the left

Hope this helps :)
