Answer:
a). Y = y0e^-k(t)
b) Y = 19.4 Unit mass
Step-by-step explanation:
Y = y0e^-k(t)
Where y is amount present at the time
Y0 is initial amount present at t = 0
Y0 = 58.7
Half life = 5 hours
At half life , y = 58.7/2
At half life , y = 29.35
K = decaying constant.
Let's look fithe value of k
Y = y0e^-k(t)
29.35 = 58.7e^-k(5)
29.35/58.7 = e^-k(5)
0.5 = e^-k(5)
In 0.5 = -k(5)
-0.69314718 = -k(5)
0.138629436 = k
The value present in 8 hours will be
Y = y0e^-k(t)
Y = 58.7e-0.138629436(8)
Y = 58.7e-1.109035488
Y = 58.7(0.329876978)
Y= 19.36377861
To the nearest tenth
Y = 19.4 unit of mass

A kite is flying at an angle of elevation of 48 degrees
Answer:
<u>B</u>
Step-by-step explanation:
Observation : Graph is opening up, means end behaviour is same that is graph is ending in the same side .
So the graph must represent a even degree polynomial .
Observation : Graph is opening on the positive side of the y axis .
It means the leading coefficient of the polynomial must be positive .
So we are looking for the option which have even degree and the leading coefficient is positive . The correct option is B .
