Answer:
cos²x.sec²x =1 (formula)
cos and sec are reciprocal to each other
cos²x=1/sec²x
now from the eq above,open the brackets and multiply
1-cos²2x
sin²2x
Its 0.8333 as percent! Hope that helps! :3
And feel free to pm me if you have anymore questions. ! :3
Answer:
The contribution margin it's determined by the total amount of Gross Profit divided by the total value of sales.
Profit = $405,000
Sales = 11,250×106 =$1,192,500
Therefore contribution margin ratio = ($405,000/$1,192,500) = 0.34
The Break Even point is given thus;
Fixed cost = 25 × 11250 =$281,250
Break-even point = Fixed costs ÷ contribution ratio
= $281,250/0.34 = $827,205.88
Given:
Mrs. Kato has 6 bags of dried beans and a 2-pound bag of rice in one shopping bag.
In another shopping bag she has a 5-pound bag of flour.
The two shopping bags weigh the same amount.
To find:
The weight of each bag of dried beans.
Solution:
Let x be the weight of each bag of dried beans.
So, weight of 6 bags of dried beans = 6x.
According to the question,
Weight of first bag = (6x + 2) pounds
Weight of second bag = 5 pounds
The two shopping bags weigh the same amount. So,



Divide both sides by 6.


Therefore, the weight of each bag of dried beans is 0.5 pounds.
The original expression is given by:

The correct way to rewrite the expression is given by:

For this, we use two properties:
Associative property:
The way of grouping the factors does not change the result of the multiplication:
Commutative property:
The order of the factors does not vary the product:
