Area of half circle is (pi)r^2/2
d=3 r=d/2
r=3/2 or 1.5
(pi)×1.5^2/2
7.065/2= 3.5325ft^2
A.
It is exponential because the x is listed as an exponent rather than a variable attached to a coefficient.
Answer:
--3 ±sqrt((-3)^2 -4(4)(-9))

2(4)
Step-by-step explanation:
4x^2-5=3x+4
We need to get this in standard form to answer the question
Subtract 3x from each side
4x^2-3x-5=3x-3x+4
4x^2-3x-5=+4
Subtract 4 from each side
4x^2-3x-9 =0
a = 4
b = -3
c = -9
-b ±sqrt(b^2 -4ac)
---------------------------
2a
--3 ±sqrt((-3)^2 -4(4)(-9))
-------------------------------
2(4)
Answer:
There would be 6 candles.
Step-by-step explanation:
So you said that there would be 2 candles per 20 cakes, so I simplified it to 1 candle per 10 cakes. So, if there were 60 cakes, there would be 6 candles.
I hope it helped!

Answer:
--- equation
--- value at 5th year
Step-by-step explanation:
Given
decrease
Required
Determine the linear equation
Determine the value at the 5th year
Represent years with x.
If the rate in 1 year is 2200,
in x years, it'll be 2200x (decrement)
So, the value (y) at x years is.
The value at the 5th year is when x = 5.
So, we have:
