Answer:
Option A ( radius is twice the daimeter )
Step-by-step explanation:
The relationship between radius and daimeter is given as
Radius² = Daimeter ⇒ r² = d
And cricumference can be calculated with radius
As circumference is 2πr
Answer:
250
Step-by-step explanation:
There is a 200 start up cost plus 50 per month
Cost = 200 + 50m where m is the number of months
We have 1 month
Cost = 200 +50(1)
Cost = 250
Answer:
in confused on what the question is asking is it multiple questions
The equation of a circle with centre (a,b) and radius r is:
(x - a)^2 + (y - b)^2 = r^2
thus,
here centre (a,b) = (-3,6), a = -3, b = 6
and radius = diameter/2 = 20/2 =10 units
therefore, the equation is
(x + 3)^2 + (y - 6)^2 = 100
which is c.
Answer:
They have the same y-intercept.
Step-by-step explanation:
The y-intercept occurs when x = 0 so for f(x):
y-intercept = f(0) = -6(0) - 3 = -3.
For h(x):
y-intercept = h(0) = 2 cos(0 + pi) - 1
= 2 cos pi - 1
= 2 *-1 - 1 = -3.
