The value of the given trigonometric expression which is cos 2θ under the 3rd quadrant is; -119/169
What is the value of the trigoneometric ratio?We are given the trigonometric ratio;
sin θ = -⁵/₁₃
From trigonometric identities, we know that;
cos 2θ = 1 - 2sin²θ
Thus;
cos 2θ = 1 - 2(-⁵/₁₃)²
cos 2θ = 1 - 2(25/169)
cos 2θ = 119/169
since cos θ is negative in the third quadrant, then we have;l
cos 2θ = -119/169

Suppose the government in this economy decides to decrease government purchases by $250 billion. the decrease in government purchases will lead to a decrease in income, generating an initial change in consumption equal to . this decreases income yet again, causing a second change in consumption equal to . the total change in demand resulting from the initial change in government spending is .
When the government decides to decrease government purchases by $250 billion, this will lead to a $175 billion decrease in income.
How to calculate the decrease in income?From the information, the government decides to decrease government purchases by $250 billion. The decrease in income will be:
= $250 × 0.7
= $175 billion
This decrease in income yet again will cause a second change in consumption equal to:
= $175 × 0.7
= $122.5 billion
The total change in demand resulting from the initial change in government spending will be:
= $250 × (1/30%)
