Answer:
I'm pretty sure that they are 4, 16, 64, and 256.
Step-by-step explanation:
<span>circumference of circle = 2*pi*r
given r = 5
so circumference = 31.42
now we know 360 degree is uniformly distributed on this circumference
so x/360=10/31.42
so x= 114.65
so option C.) 114.65 is the answer</span>
Answer:
x = 1
Step-by-step explanation:
plug y = 6 on to the equation y =x + 5
=> 6 = x +5
=> x = 1
Answer:
y = (x-3)^2 -16
Step-by-step explanation:
y = x^2 -6x-7
We need to complete the square
b= -6
b/2 = -6/2 = -3
(b/2) ^2 = (-3)^2 =9
Add 9 then subtract 9 to balance the equation
y = x^2 -6x +9 -9 -7
y = (x^2 -6x+9) -16
The terms in parentheses is (x-b/2)^2
y = (x-3)^2 -16
This is in vertex form
The vertex is (3,-16)
Let
be the temperature of the body
hours after 1:30 PM. Then
and
.
Using Newton's Law of Cooling,
, we have
. Now let
, so
, so
is a solution to the initial value problem
with
.
By separating and integrating, we have
.
≈ 95 minutes. Thus the murder took place about 95 minutes before 1:30 PM, or 11:55 AM.
