Write each relation in standard form and then find the y-intercept for each relation:
1 answer:
Answer:
In standard form, the relation is
The y-intercept is y = 507.
Step-by-step explanation:
Quadratic equation:
In standard form, it is written as:
The y-intercept is c.
a) y = 5(x+10)^2 +7
We open the binomial to write in standard form. So
In standard form, the relation is
The independent term, c, is 507, so the y-intercept is y = 507.

Answer:
25
Step-by-step explanation:
From the given information;
Numbers of posters that can be printed in an hour = no of impression/hour × no of plate utilized in each impression.
= 1000x
Thus, the required number of hours it will take can be computed as:
cost per hour = 125
If each plate costs $20 to make, then the total number of plate will equal to 40x
∴
The total cost can be computed as:
At C'(x) = 0
x = 25
where; x = 25
C''(x) = 1.6
Thus, at x = 25, C'' > 0
As such, to minimize the cost, the printer needs to make 25 metal plates.
