If cos theta is -5/13 and sin θ < 0, what is tan θ ?

tensa zangetsu [6.8K]

Take the right angled triangle with sides 13, 12 and 5. sine theta will be 12/13

When sin theta < 0 and cos theta < 0 we are in the third quadrant so sin theta will be -12/13

tan theta = sin theta / cos theta = -5/13 / -12/13 = -5*13 / -12*13 = 5/12

If two of these shapes are randomly chosen, one after the other without replacement, what is the probability that the first will

aleksandrvk [35]

Answer:

$P(T\ n\ S) = \frac{1}{14}$

Step-by-step explanation:

*Missing Part of the Question*

4 stars

5 triangles

3 circles

3 squares

Required

Determine the probability of triangle being first then square being second

$Total = 4 + 5 + 3 + 3$

$Total = 15$

Represent the triangle with T and square with S

So, we're solving for P(T n S)

$P(T\ n\ S) = P(T) * P(S)$

Solving for P(T)

$P(T) = \frac{n(T)}{Total}$

$P(T) = \frac{5}{15}$

Solving for P(S)

The question implies a probability without replacement;

Hence Total has now been reduced by 1

Total = 14

$P(S) = \frac{n(S)}{Total}$

$P(S) = \frac{3}{14}$

Recall that

$P(T\ n\ S) = P(T) * P(S)$

$P(T\ n\ S) = \frac{5}{15} * \frac{3}{14}$

$P(T\ n\ S) = \frac{15}{15 * 14}$

$P(T\ n\ S) = \frac{1}{14}$

Hence, the required probability is

$P(T\ n\ S) = \frac{1}{14}$

Dave uses 5 gallons of gas to drive 140 miles on the highway. If he travels at the same rate, how many miles can he drive on 7 g

Solnce55 [7]

Answer:

168 miles

Step-by-step explanation:

If he uses 5 gallons to drive 140 miles, that means that he can drive 24 miles for every gallon (140/5=24)

7 times 24 is 168 so he can drive 168 miles on 7 gallons of gas
