Answer:
The value of (x + y)³ is 1728.
Step-by-step explanation:
First, you have to find the value of x + y :
x² + 2xy + y² = 144
x² + xy + xy + y² = 144
x(x + y) + y(x + y) = 144
(x + y)(x + y) = 144
(x + y)² = 144
x + y = √144
x + y = 12
Next, the value of (x + y)³ :
(x + y) = 12³ = 1728
(x+y)³=1728
(x+y)²=144=12²
(x+y)³=12*12*12=1728
Y= 1/2 cos4X (Option 3)
It cuts axis at 0.5
y-intercept for x = 0.
Substitute x = 0 to the equation of the function:
a. 5i + 13j
b. 8i
c. 10i + 6j
a. 2i + 6j + 3i + 7j = 5i + 13j
b. 3i + 7j + 5i - 7j = 8i
c. 2i + 6j + 3i + 7j + 5i - 7j = 10i + 6j
