Answer:
2 sin A / cos 3A + 2 sin 3A / cos 9A + 2 sin 9A / cos 27A = tan 27A - tan A
2 sin A/cos 3A
Multiply with cos A to Numerator and denominator
= 2 sin A cos A/cos 3A cos A
Formula (sin 2A = 2 sin A cos A)
= sin 2A / cos 3A cos A
Formula [ (sin a-b) / cos a cos b = tan a - tan b ]
So,
= sin 3A - A / cos 3A cos A
= tan 3A - tan A----> Equation 1
Apply same procedure we get
2 sin3A / cos 9A = tan 9A - tan 3A---> Equation 2
2 sin 9A / cos 27A = tan 27A - tan 9A----> Equation 3
Add Equation 1,2 and 3
tan 3A - tan A + tan 9A - tan 3A + tan 27A - tan 9A = tan 27A - tan A
2 sin A / cos 3A + 2 sin 3A / cos 9A + 2 sin 9A / cos 27A = tan 27A - tan A

14. Which is the next level of government that responds to an incident when it has the potential to expand beyond the
capability of local jurisdiction?
A Foreign goverment
B Private Sector
C. Federal government
D. State government
Hey,
Answer:
When an incident grows beyond the capability of a local jurisdiction, and responders cannot meet the needs with mutual aid and assistance resources, the next step is usually a request for: Activation of the state/territorial emergency operations center.
Federal government is the next level of government that responds to an incident when it has the potential to expand beyond the capability of the local jurisdiction. Therefore option C is correct.
When an incident has the potential to expand beyond the capability of local jurisdiction, the next level of government that typically responds is the Federal government.
Local governments, such as cities and counties, are usually the first to respond to incidents within their jurisdiction.
However, if the incident exceeds their resources and capabilities, they may request assistance from the higher level of government.
The Federal government has broader authority, resources, and expertise to address large-scale incidents that could impact multiple jurisdictions or have national implications.
Federal agencies like FEMA (Federal Emergency Management Agency) and other departments are responsible for coordinating and providing support during emergencies or incidents that surpass the capacity of local and state governments.
Therefore option C Federal government is correct.

The correct answer is - macular degeneration and xerophthalmia
Explanation:
With retinoids, carotenoids are likewise significant for legitimate vision. Higher carotenoid content in the eye is related to lower risk for age-related macular degeneration, a type of visual impairment wherein the definite sight in the focal point of the field of vision is lost. Carotenoids are likewise helpful in the anticipation of cataracts, a condition where the focal point of the eye gets overcast.
Light enters the eye through the cornea and focal point and arrives at the coating at the rear of the eye, called the retina. This lining is home to specific kinds of cells that require vitamin A for typical capacity. The poles distinguish highly contrasting and are liable for night vision. The cones are answerable for shading vision
For the safeguarding of visual capacity, contemplates demonstrating that expending carotenoids from nourishments is more advantageous than carotenoids from supplements.
At the point when nutrient An is lacking, the cells in the eye can't modify from splendid to diminish light, a condition known as night visual deficiency. In extreme instances of nutrient A lack, cells in the cornea of the eye lose the capacity to create bodily fluid, prompting xerophthalmia.
