Can someone pls help for brainlest
Lerok [7]

Answer:

6.28km

Step-by-step explanation:

Hey,

We know that the circumfrence is the perimetert of a full circle. If we want to find the perimeter of a semicircle all we have to do is find the circumfrence and then divide it by 2 since we want to know the perimeter of half the circle.

Circumfrence is equal to 2πr. Where r is the radius and since we know the radius we an solve for the circumfrence.

2(π)(1km)=2kmπ.

The problem tells us to use 3.14 for pi so let's multiply 2 by 3.14.

6.28km is the answer!

Factor completely. x2+7x−18 Enter your answer in the box.<br> 50 POINTS
Aliun [14]
The first step to solving this is to write 7x as a difference
x² + 9x - 2x - 18
next you need to factor out x from the expression
x × (x + 9) - 2x - 18
then you'll need to factor out -2 from the expression
x × (x + 9) - 2 (x + 9)
lastly,, you need to factor out x + 9 from the expression
(x + 9) × (x - 2)
this means that the correct answer to your question is (x + 9) × (x - 2).
let me know if you have any further questions

A parabola can be represented by the equation x2 = 2y. What are the coordinates of the focus and the equation of the directrix?
Vera_Pavlovna [14]

Answer:

the coordinate of the focus is: (0, 1/2)

the equation of the directrix is: y=-1/2

Step-by-step explanation: The standard equation for a parabola that opens upward- parallel to the y-axis, is: x2=4ay. Meaning, a = distance from the vertex to focus and the vertex is at origin: (0,0).

4a is equal to 2

a is equal to 2/4

a is equal to 1/2 or 0.5

Please explain what mark up is to me. Keep it simple
iogann1982 [59]

Hey there!

Markup is the percentage that the cost of an item is increased.

For example, if a company bought a pair of headphones that costed $100 and they sold it for $150, the markup was 50%, since half of the original cost was added. if the markup were 100% it would have been sold for $200, since it added 100% of the original.

I hope this helps!
