Answer:
Step-by-step explanation:
y = 0.80x + 2.50
a 7 mile ride......x = 7
y = 0.80(7) + 2.50
y = 5.60 + 2.50
y = 8.10 <=== the 7 mile ride cost $ 8.10
the ride cost 13.70.....y = 13.70
13.70 = 0.80x + 2.50
13.70 - 2.50 = 0.80x
11.2 = 0.80x
11.2 / 0.80 = x
14 = x <=== u travel 14 miles
Step-by-step explanation:
10 %, 7/10 and 0.2 are the three numbers that add up to 1
0.1 + 0.7 + 0.2 = 1
Answer:
50
Step-by-step explanation:
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.
