Answer:
The money invested in account at 6 % rate is $ 9230.77
The money invested in account at 6.5 % rate is $ 769.23
Step-by-step explanation:
Given as :
The total amount saves in two account = $ 10,000
The two rate of interest are 6 % and 6.5 % at simple interest
The interest earn at 6 % rate = $ 632
The interest earn at 6.5 % ate = $ 50
Now, Let The amount deposit at 6 % rate = $ x
And The amount deposit at 6.5 % rate = $ 10,000 - $ x
<u>From Simple Interest method</u>
Simple Interest =
or, At 6.5 % rate
$ 50 =
or, 10000 - x =
Or, 10000 - x = 769.23
∴ x = 10000 - 769.23
I.e x = $ 9230.77
So , At 6.5 % the amount deposit = 10,000 - 9230.77 = $ 769.23
So, At 6 % The amount deposit = $ 9230.77
Hence The money invested in account at 6 % rate is $ 9230.77
And The money invested in account at 6.5 % rate is $ 769.23 Answer
Answer:
A, C
Step-by-step explanation:
Actually, those questions require us to develop those equations to derive into trigonometrical equations so that we can unveil them or not. Doing it only two alternatives, the other ones will not result in Trigonometrical Identities.
Examining
A) True
Double angle
B) False,
No further development towards a Trig Identity
C) True
Double Angle Sine Formula
D) False No further development towards a Trig Identity
