Answer:
D 0.62
Step-by-step explanation:
90-38 = 52
cos (52) = .62
Unfortunately, there are no given choices. However, I could provide the possible inequalities from the given problem. Converting the given to inequalities:
3.2x + 0.8y < 50
x + y = maximum
There is no other limiting equation (i.e. the total cost of the books) such that the, if you wanted to maximize x, results to minimum y and vice versa.
Hi there! :)
Answer:
y = -2x + 3
Step-by-step explanation:
We can write an equation in slope-intercept form. Use the slope formula to find the rate of change in the table:
Plug in values from the table:
Simplify:
m = -2 (rate of change)
Use a point from the table (-2, 7) and the slope to solve for the equation for the linear function:
7 = -2(-2) + b
7 = 4 + b
7 -4 = b
b = 3
Rewrite:
y = -2x + 3 is the equation for the linear function.
Answer:
d = 17
Step-by-step explanation:
The given arithmetic sequence is :
31, 48, 65, 82, ...
We need to find the common difference for this sequence.
First term, a₁ = 31
Second term, a₂ = 48
Common difference = a₂-a₁
= 48-31
= 17
So, the common difference for this arithmetic sequence is equal to 17.
