Answer:

38cm is the circumference

Explanation:

circumference = diameter x 3.14

diameter = 12

circumference = 3.14 x 12 = 37.68

Now we need to round to the nearest whole

36 and 38 are the nearest wholes to 37.68. We need to minus and then find smallest difference between the numbers; meaning the smaller the difference the closer it is.

37.68 - 36 = 0.68

38 - 37.68 = 0.32

37.68 is more closer so we can round this to 38.

Find the domain of the following expression 15 - √(x+2)
ipn [44]

Answer:

[-2, ∞]

Step-by-step explanation:

15 - √(x+2)

domain is any value as long as (x+2) is not-negative, since √ of a negative number has no Real solution.

x+2 ≥ 0 ⇒ x ≥ -2

What is the equation of the line that passes through (–2, 3) and is parallel to 2x + 3y = 6?
Zinaida [17]
2x + 3y = 6
3y = - 2x + 6
y = -2/3x + 2....slope here is -2/3
A parallel line will have the same slope

y = mx + b
slope(m) = - 2/3
(-2,3)...x = -2 and y = 3
now we sub, we r looking for b, the y intercept
3 = -2/3(-2) + b
3 = 4/3 + b
3 - 4/3 = b
9/3 - 4/3 = b
5/3 = b

ur equation is : y = -2/3x + 5/3 (slope intercept form)

y = -2/3x + 5/3
2/3x + y = 5/3
2x + 3y = 5 (standard form)
