A bookcase has two shelves. The top shelf has 10 more than 1/3 the number of books on the bottom shelf. There are 12 books on th
kobusy [5.1K]

Answer: b.14

Step-by-step explanation:

We have two shelves, the top shelf s_{t} and the bottom shelf s_{b}.

Now, firstly we are told the top shelf has 10 more than 1/3 the number of books on the bottom shelf. This can be expressed as:

s_{t}=10+\frac{1}{3}s_{b} (1)

Then, we are told there are 12 books on the bottom shelf:

s_{b}=12 (2)

Substituting (2) in (1):

s_{t}=10+\frac{1}{3}(12) (3)

s_{t}=10+\frac{12}{3} (4)

s_{t}=14 (5) This is the number of books on the top shelf

Hence, the correct option is b.

Suppose that Sin(θ)=5/13 and cos(θ)=-12/13. Find the value of tan(θ), cot (θ), CSC (θ), and sec (θ). Find the value of tan(2θ)
horrorfan [7]

Answer:

Because θ lies in quadrant II, 2θ must lie in quadrant IV. This means the tangent of 2θ is negative.

The adjacent side to θ is 7 because √(25²-24²)=7, so tanθ=7/24.

The double angle formula for tangent is tan 2θ = (2 tan θ) / (1 − tan² θ).

Substituting the value for tanθ in and keeping in mind that this is in quadrant IV, we get tan 2θ = -(2(7/24)/(1-(7/24)²)).  

Simplified, this becomes tan 2θ = -336/527.  

Therefore, the answer is C. -336/527.
