Answer:
answer????
Step-by-step explanation:
Answer
D. -3x + 4(2x-6) + 5
Step-by-step explanation:
-3x has nothing attached to it so leave it alone
4 times 2x equals 8x and 4 times -6 equals -24
add 5
8x-3x=5x
-24 + 5 = -19
5x - 19
Answer:
The correct option is;
Decrease b.
Step-by-step explanation:
The given information are;
The function in the question is given by the equation, y = a·cos(b·x)
Where;
a > 0 and b > 0
The location of the x-intercept is given by the values of x when y = 0 which are obtained as follows;
When y = 0, y = a·cos(b·x) = 0
Therefore;
cos(b·x) = 0/a = 0
∴ b·x = cos⁻¹(0) = π/2, 3·π/2, (4·n×π + π)/2
Therefore, as b decreases, x increases.
The answer is 120 instead of 12 because 12 equals 7.2
