K = 4a + 9ab
K = a (4 + 9b)
K / (4 + 9B) = a
check the picture below.
so the playground is really just 3 rectangles and one triangle, now the triangle has a base of 8 and a height of 6. We can simply get the area of each figure, sum them up and that's the area of the playground.
Answer: + =
Step-by-step explanation:
The equation of a circle is given as :
+ =
Where (a,b) are the coordinate of the center and r is the radius of the circle.
The end point of the diameter is give as (-5, -3 ) and ( -11 , -3 ) , This means that we can find the coordinate of the center by finding the mid point of the end point. The mid point is calculated by :
Mid point = ( , )
= -5
= -11
= -3
= -3
Substituting this values into the formula for finding mid point , we have
Mid point = ( ,
Mid-point = (-8 , -3)
Remember that Radius is half of the diameter , To find the diameter we must find the distance between the two end point using the formula for calculating distance between two points , that is
D =
Substituting the values :
D =
D =
D = 6
Therefore , The diameter i s 6
And since radius is half of the diameter , radius is thus
r = 6/2
r = 3
So , substituting the values gotten into the equation of circle , we have:
+ =
+ =
Answer:
hold up i did this already
Step-by-step explanation:
Answer:
Charges interest if balance is not paid each month.
Step-by-step explanation:
You'll be charged interest whenever you don't pay the full balance from the previous billing cycle.
You'll be charged interest any month you make a cash advance or other type of transaction that does not have a grace period or if your credit card doesn't have a grace period at all.
The sum of interest on your credit card account and it is broken down by transaction type: purchases, cash advances and balance transfers. You will be charged interest if you pay less than the full balance or pay after the payment due date.
Hope this helps!
