Answer is -28.37
Step-by-step explanation:
from the numerator cos 2a×cos 3a - cos 2a×cos7a= cos6a^2 -cos 14a^2
= -cos8a^2 for the numerator
from the denominator;
sin4a×sin3a-sin2a×sin5a= sin12a^2 -sin10a^2
= sin2a^2
therefore, combining the equation it gives; -cos8a^2/sin2a^2
a^2 will divide each other,
= -cos8/sin2.
from the calculator,
= - 0.9903/0.0349
= -28.37
Answer:
because this organic process need more time to produce food.
Step-by-step explanation:
since in the organic farming or agriculture, there is not use of hormones or pesticides, the plants and animals grow slowly, if they have more nutrients than the normal food, they spend more time, that is the reason why they are expensive, not just because the hour-human - work is bigger, also because the time to return the incomes are longer.
Hope this info is useful.
Answer:
Third option: 5.48
Step-by-step explanation:
Given the quadratic model that represents the approximate height in meters of the ball 
. the time in seconds x, when the ball is 50 meters from the ground can be calculated by substituting 
and solving for x.
Then:
Subtract 200 from both sides:
Divide both sides by -5:
Apply square root to both sides:
The ball is 50 meters from the ground after about 5.48 seconds.
B. 94 because it is the same as the other one
