Which do you think is the best description of the area of the room? (circle your choice.)

1 answer:

3 0

My vote would be b. because generally when we are figuring area of a room, we are working with materials that are not exact and we usually round off .75 to the next foot. (I have experience in flooring!)

I am sure there are situations where you would want it to be exact however, such as using VERY expensive materials to cover.

Prove the identity 2csc2x=csc^2xtanz

Verizon [17]

Step-by-step explanation:

Consider the LHS, after the 5th step, consider the RHS

$2 \csc(2x) = \csc {}^{2} (x) \tan(x)$

$2 \frac{1}{ \sin(2x) } = \csc {}^{2} (x) \tan(x)$

$2 \times \frac{1}{2 \sin(x) \cos(x) } = \csc {}^{2} (x) \tan(x)$

$\frac{1}{ \sin(x) \cos(x) } = \csc {}^{2} (x) \tan(x)$

$\csc(x) \sec(x) = \csc {}^{2} (x) \tan(x)$

Consider the RHS

$\csc(x) \sec(x) =( 1 + \cot {}^{2} (x) ( \tan(x))$

$\csc(x) \sec(x) = \tan(x) + \cot(x)$

$\csc(x) \sec(x) = \frac{ \sin(x) }{ \cos(x) } + \frac{ \cos(x) }{ \sin(x) }$

$\csc(x) \sec(x) = \frac{1}{ \sin(x) \cos(x) }$

$\csc(x) \sec(x) = \csc(x) \sec(x)$

If the interest rate on a savings account is 0.02%, approximately how much money do you need to keep in this account for 1 year

astraxan [27]

At first glance, this problem might be overwhelming so try approaching it slowly by doing these steps:

Step 1: Start by understanding what the problem is really asking.
You might notice that the problem is just a percentage problem, with a twist! If you still don't see it, the problem is just asking what the base should be given a percentage and the amount.

Step 2: Recall the concepts relevant to the question.
We can identify a single formula that will be important in getting the answer:
$base*percent=amount$

Step 3: Apply the concept to the context of the problem.
You'll see that we already have the percent from the interest rate which is 0.02% and the amount from the below-minimum-balance fee which is $9.99.

There goes the little twist: you have to manipulate the equation to get the base. Dividing both sides of the equation by the percent we'll have:
$base= \frac{amount}{percent}$

Step 4: Evaluate to get the answer to the problem.
We simply substitute the given numbers and evaluate.
$base= \frac{percent}{amount}= \frac{9.99}{0.0002} =49,950$

Answer: You need $49,950 in the account to cover the Below-Minimum-Balance Fee from your interest.
