Answer:
4600 grams of peanuts
Step-by-step explanation:
For 2 kg of peanuts the customer will get 300 g free.
So if 4 kg of peanuts the customer will get 600 g free.
1kg = 1000g
If 4kg, thus it is 4000g
All mass of peanut the customer gets is 4000g + 600g = 4600g of peanuts.
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.
