Answer:
0.36
Step-by-step explanation:
A= K/B^2
K= A × B^2
K= 1 × 3^2
K= 1×9
K= 9
Therefore if B is 5 then A can be calculated as follows.
K= A × B^2
9= A × 5^2
9= A × 25
9= 25A
A= 9/25
A= 0.36
Hence A is 0.36
Answer:
71
-133
Step-by-step explanation:
Given the polynomial :
3x³– 4x² + 7x + 5, when x = 3 and also when
x = –3.
Put x = 3
3(3)³– 4(3)² + 7(3) + 5
3(27) - 4(9) + 21 + 5
81 - 36 + 21 + 5
= 71
Put x = - 3
3(-3)³– 4(-3)² + 7(-3) + 5
3(-27) - 4(9) - 21 + 5
-81 - 36 - 21 + 5
= - 133
Age of Sita is 14.25 years and her father is 42.75 years
Step-by-step explanation:
- Step 1: From given details, let present age of Sita be x and that of her father be 3x.
- Step 2: Form equations based on their ages in 6 years. (Given sum is 69)
⇒ (x + 6) + (3x + 6) = 69
⇒ 4x + 12 = 69
⇒ 4x = 57
⇒ x = 14.25
- Step 3: Calculate age of Sita's father
⇒ 3x = 42.75
Y= 12*x
Y=12x
In short, y is a product of 12 and x
