Answer: (-1,2)
Step-by-step explanation:
Lst question: x = 5, y = 7
2nd question: x = -1, y = 5
3rd question: x = 98, y = 80
Answer
N = 32 ÷ (5 - 1)
N = 32 ÷ 4
N =8
Step-by-step explanation:
Given two functions are
f(x) = 2 cos(x)
g(x) = 3 sin(x+
)
We know that the maximum value of cos x and sin x is always 1
y= maximum of cos = 1
y= maximum of sin =1
f(x) = 2 cos(x)
y= 2 (max of cos) = 2(1) = 2
g(x) = 3 sin(x+
)
y= 3 (max of sin) = 3(1) = 3
g(x) = 3 sin(x+
) has the maximum value.
