How do you solve: secx=-5/2, tanx&lt;0<br><br> Find all six trig functions
Brut [27]

Answer:

sec theta = (sqrt24/5) cos theta = -2/5 tan theta = (-[sqrt 21]/2) sec theta = 5/2 csc theta = (5sqrt21)/21 cot theta = (-2sqrt21)/21

Step-by-step explanation:

During the problem, secx = -5/2, we can assume that as cos = -2/5. -2 = x. 5 = r. find for Y with: x^2+y^2=r^2. After that, plug in for the variables and you get all the answers. Rationalize the square roots, don't forget.

Determine the term life insurance amount per thousand on a 22-year-old female for a 5-year policy given that the face value of t
VLD [36.1K]

We need to determine the term life insurance amount per thousand on a 22-year-old female for a 5-year policy given that the face value of the policy is $600,000 and the annual premium is $1332.

Since we are supposed to find the term life insurance amount per thousand, therefore, we will use the following formula:

\text{Term life insurance amount}=\frac{\text{Annual premium}}{\text{Face value of insurance}}*1000

Upon substituting the values of annual premium and face value of insurance, we get:

\text{Term life insurance amount}=\frac{\text{1332}}{\text{600000}}*1000\\&#10;\text{Term life insurance amount}=\$2.22

Therefore, the required life insurance amount is $2.22.
