Answer:
1.54 [km²].
Step-by-step explanation:
1) the given scale is for linear functions, the given area of the lake is quadratic function. According to this
2) actual area = given area *50000 *50000;
3) the given area=0.000616 [m²],
the actual area=0.000616*50000*50000=1540000 [m²] or 1.54 [km²].

Answer:
The length of pendulum is 55.853cm
Step-by-step explanation:
We are given
the original pendulum completed one swing every 1.5 seconds
so, T=1.5 sec
now, we can use time period formula

l is the length of pendulum
g is acceleration due to gravity

now, we can plug values
and then we can solve for l



In cm

Answer:
6x+19
Step-by-step explanation:
distribute the six to get 6x+12+7
combine like terms 6x+19
move 19 to other side 6x=19
divide by 6
x=3.1666666667
