Answer:
8.71 x 10^3N - C
Step-by-step explanation:
Force = mass x acceleration
mass = 1.7 x 10^3 and acceleration = 4.75m/s^2
Force = 1.7 x 10^3 x 4.75 = 8075N = 8.71 x 10^3N
Sorry I can’t see the picture it’s blurry for me
Answer:
The values of x and y are x = -3 and y = -2
Step-by-step explanation:
In the complex numbers if a + bi = c + di, then the real parts are equal and the imaginary parts are equal
Let us use this rule to solve the question
∵ -21 + 5yi = 7x - 10i
∴ The real parts are -21 and 7x
∴ The imaginary parts are 5y and -10
∵ The real parts are equal
∴ 7x = -21
→ Divide both sides by 7
∴ =
∴ x = -3
∵ The imaginary parts are equal
∴ 5y = -10
→ Divide both sides by 5
∴ =
∴ y = -2
∴ The values of x and y are x = -3 and y = -2
