Answer:
[tex]\cot(\theta)[/tex]
Step-by-step explanation:
Trig identities:
[tex]\csc(\theta)=\dfrac{1}{\sin(\theta)}[/tex]
[tex]sin^2(\theta)+cos^2(\theta)=1[/tex]
[tex]\cos(2\theta)=cos^2(\theta)-sin^2(\theta)[/tex]
[tex]\implies \cos(2\theta)=2cos^2(\theta)-1[/tex]
[tex]\implies2cos^2(\theta)= \cos(2\theta)+1[/tex]
[tex]\sin(2\theta)=2\sin(\theta)\cos(\theta)[/tex]
Therefore,
[tex]\dfrac{\cos(2\theta)+\sin(\theta) \times \csc(\theta)}{\sin(2\theta)}[/tex]
[tex]=\dfrac{\cos(2\theta)+\dfrac{\sin(\theta)}{\sin(\theta)}}{\sin(2\theta)}[/tex]
[tex]=\dfrac{\cos(2\theta)+1}{\sin(2\theta)}[/tex]
[tex]=\dfrac{2cos^2(\theta)}{\sin(2\theta)}[/tex]
[tex]=\dfrac{2cos^2(\theta)}{2\sin(\theta)\cos(\theta)}[/tex]
[tex]=\dfrac{cos(\theta)}{\sin(\theta)}[/tex]
[tex]=\cot(\theta)[/tex]
10. If the Federal Reserve sells $50,000 in Treasury bonds to a bank at 8%
interest, what is the immediate effect on the money supply?

C. It is decreased by $55,500.
D. It is increased by $55,500.
Answer:
b
Step-by-step explanation:
The immediate effect on the money supply when the Federal Reserve sells $50,000 in Treasury bonds to a bank at 8% interest is that It is decreased by $50,000.
Option A is the correct answer.
We have,
When the Federal Reserve sells Treasury bonds to a bank, it takes money out of the banking system.
The concept used in this scenario is the Open Market Operations (OMO) conducted by the central bank, which in this case is the Federal Reserve.
Open Market Operations refer to the buying and selling of government securities, such as Treasury bonds, by the central bank in the open market.
The bank pays $50,000 to the Federal Reserve to purchase the bonds, and this money is removed from the money supply, leading to a decrease in the overall money supply in the economy.
Thus,
The immediate effect on the money supply is:
A. It is decreased by $50,000.

Jack bought 3 slices of pizza and 4 slices f mushroom pizza for a total cost of $12.50. Grace bought 3 slices of cheese pizza and 2 slices of mushroom pizza for a total cost of 8.50. What is the cost of one slice of mushroom pizza?
A. $3.00
B. $1.50
C. $2.00
D. $3.50
PLEASE HELP ♡
Answer:
C
Step-by-step explanation:
Let's set up a simultaneously equation to solve for two unknows.
Let x be the cost of cheese pizza
Let y be the cost of mushroom pizza
"Jack bought 3 slices of pizza and 4 slices f mushroom pizza for a total cost of $12.50."
Therefore,
3x + 4y = 12.50 (Equation 1)
"Grace bought 3 slices of cheese pizza and 2 slices of mushroom pizza for a total cost of 8.50."
Therefore,
3x + 2y = 8.5 (Equation 2)
From equation 1, let's solve for x in terms of y
3x + 4y = 12.50
3x = 12.50 - 4y
[tex]y = \frac{12.50-4y}{3}[/tex]
Plug in this y value into equation 2, we have:
[tex]3(\frac{12.50-4y}{3}) + 2y = 8.5[/tex]
We will get that y = 2
Hence, option C is the answer.

2.) Consider the quadratic equation 6x^2+11x-10=0
A.) solve it by using zero product property
Step-by-step explanation:
Roots Theorem
[tex]6 {x}^{2} + 11x - 10 = 0[/tex]
Use the AC method,
The roots must multiply to -60 and add up to 11.
Those two numbers are 15 and -4
So we have know
[tex]6 {x}^{2} + 15x - 4x - 10 = 0[/tex]
[tex]3x(2x + 5) - 2(2x + 5)[/tex]
[tex](3x - 2)(2x + 5) = 0[/tex]
Set each binomial equal to zero
