6 0

Answer:

Hence Proved

Step-by-step explanation:

  • To Prove that
  • Sin 80 - Cos 110 = \sqrt{3}× Sin 50
  • <em>Cos 90+∅ = -Sin ∅</em>
  • Sin 80 - Cos 90+20 = \sqrt{3}× Sin 50
  • Sin 80 -(-Sin 20) = \sqrt{3}×Sin 50
  • Sin 80 + Sin 20 = \sqrt{3}×Sin50
  • <em>Sin A +Sin B = 2Sin (A+B)/2Cos(A-B)/2</em>
  • 2Sin (80+20)/2Cos (80-20)/2 = \sqrt{3}×Sin50
  • 2Sin 50Cos 30 = \sqrt{3}×Sin50
  • Cos 30 = \sqrt{3}/2
  • 2×\sqrt{3}/2×Sin50 = \sqrt{3}×Sin50
  • \sqrt{3}×Sin50 = \sqrt{3}×Sin50
  • Hence proved

Answer:

A. $307,172.72

Step-by-step explanation:

Inez has to pay 4 percent in closing costs and 16 percent for the down payment on a purchase of $225,500 with an ARM.

4% + 16% = 20%

lnez has to pay 20% of $225,500

= 225,500*20/100

= 225,500*0.2

= $45100

lnez has to pay $45100.

Over the life of the loan, lnez will pay $262,072.72

Now we have to add down payment, closing cost and the payment over the life of the loan.

$45100 + $262,072.72

= $307,172.72

Answer: A. $307,172.72

Answer:

The multiplicative rate of change is 3/4

Step-by-step explanation:

Here, we want to get the multiplicative rate of change

In this case, by dividing the succeeding term by the preceding term, we will get the multiplicative rate of change

mathematically, we have this as;

81/128 divided 27/32

= 81/128 * 32/27

= 3/4
