Answer:
See below ~
Step-by-step explanation:
<u>Identities Needed</u>
- sec a = 1 / cos a
- cosec a = 1 / sin a
- cot a = 1 / tan a
<u />
<u>Proving</u>
- (sec²a)(cosec²a) = tan²a + cot²a + 2
<u>Taking the LHS</u>
- sec²a x cosec²a
- 1/cos²a x 1/sin²a
- 1/(sin²a)(cos²a) -(Equation 1)
<u>Taking the RHS</u>
- tan²a + cot²a + 2
- tan²a + cot²a + 2(tana)(cota)
- (tana + cota)²
- (sina/cosa + cosa/sina)²
- (sin²a + cos²a / sinacosa)²
- (1/sinacosa)²
- 1/(sin²a)(cos²a) -(Equation 2)
∴ Equation 1 = Equation 2
∴ <u>LHS = RHS</u>
Hence, proved.
Answer:
I'm not really sure but I think the answer is 21,331.20 for 3 year the interst will be 331.20
Answer:
m= 3.5
Step-by-step explanation:
You saved 4 months
1,328.9×4
=5,315.6
half in each account
5,315.6÷2
=2,657.8
CD interest
2,657.8×0.045×(45÷365)
=14.75
Saving account
2,657.8×0.032×(45÷365)
=10.49
14.95 + 10.63 = $25.58 total interest earned
Hope it helps
