Answer:
Option B:

Step-by-step explanation:
Given
Centre = (h,k) = (4,1)
Radius = r = 2
The standard equation of circle is:

Putting the values of h,k and r

Hence, the correct option is option B

Answer: The required expression is,
$ 40(0.85)
Step-by-step explanation:
Given,
The original cost of the videogame = $ 40,
Discount percentage = 15%,
So, the amount of discount = 15% of 40
= (0.15)40 ( ∵ 1% = 0.01 )
Hence, the cost of the videogame = original cost - discount
= 40 - (0.15)40
= 40 (1-0.15)
= 40(0.85)
Which is the required expression .
Sum of all the interior angles = (5-2)x180 = 540°
540 - 100 - 120 - 100 - 90 = 130°
So the last unknown angle in the polygon is 130°
Sum of all the adjacent angles on a straight line is 180°
Angle 1 = 180 - 130 = 50°
First you need to write an equation or an inequality.
5+1.80x<=12
the x here is how many miles you are paying for, now you just solve for x.
5+1.80x<=12
-5 -5
1.80x<=7
/1.80 /1.80
x<=3.8
you can travel only three whole miles, you do not have enough money to go four full miles.
540 is the answer because the doubled the first number to get the second number and multiplyed that by 3 to get the third number
