Answer:
3π in^2
Step-by-step explanation:
Area of the circle before folding = π r^2
= 6^2 π
= 36 π is^2
The area of the resulting shape = 1/2 * 1/2 * 12π
= 3 π in^2.
Equation is given as;
y = (g/k) yo
To find the value of “k”, divide both sides of the
equation with yo;
y/yo = (g/k)yo/yo
it implies that;
y/yo = (g/k)
Now following steps will obtain the value of “k” as;
ky/yo = g
ky = gyo
<span>k = gy0/y </span>
Newton's Law of Cooling states that the change
of the temperature of an object is proportional to the difference between its
own temperature and the ambient temperature over time.
Therefore when expressed mathematically, this is equivalent
to:
dT = - k (T – Ts) dt
dT / (T – Ts) = - k dt
Integrating:
ln [(T2– Ts) / (T1– Ts)] = - k (t2 – t1)
Before we plug in the values, let us first convert the
temperatures into absolute values R (rankine) by adding 460.
R = ˚F + 460
T1 = 200 + 460 = 660 R
Ts = 70 + 460 = 530 R
ln [(T2– 530) / (660 – 530)] = - 0.6 (2 - 0)
T2 = 569.16 R
T2 = 109 ºF
Answer: After 2 hours, it will be 109 ºF
Factor the numbers, starting from the smallest:
792=2*3*3*11*4
990=2*3*3*11*5
the greatest whole number that can be divided by both 792 and 990 is 2*3*3*11=198
the smallest whole number that can divide both 792 and 990 exactly is 2*3*3*11*4*5=3960
Not sure which one you are asked to find.
