Find the value of c that completes the square for the function f(x)= x2 + 4x + C.

nydimaria [60]

Answer:

$= - 4 \times 2 + 4 \times ( - 4) + c \\ = - 8 - 16 + c \\ = 24 + c \\ \frac{ - c}{ - 1} = \frac{24}{ - 1} \\ c = - 24$

A snack food manufacturer buys corn for tortilla chips from two cooperatives, one in Iowa and one in Illinois. The price per uni

aleksandrvk [35]

Answer:

a. x1 = No. of units to purchase from Iowa

x2 = No. of units to purchase from Illinois

b. Min 6x1 + 5.5x2

c. x1 + x2 ≥ 12000

x1 ≤ 8000

x2 ≥ 6000

Step-by-step explanation:

a. We can consider the variables x1 and x2 as:

x1 = No. of units to purchase from Iowa

x2 = No. of units to purchase from Illinois

b. Price per unit of Iowa corn = $6

Price per unit of Illinois corn = $5.5

Objective function that would minimize the total cost can be written as:

Min 6x1 + 5.5x2

c. The manufacturer needs at least 12000 units of corn which means that the combined number of units from Iowa and Illinois must be greater than or equal to 12000. So, we can write:

x1 + x2 ≥ 12000

The Iowa cooperative can supply up to 8000 units which means that the value of x1 must not be greater than 8000. So, we can write:

x1 ≤ 8000

Similarly, the Illinois cooperative can supply at least 6000 units which means that the value of x2 must not be less than 6000. So, we can write:

x2 ≥ 6000.

The constraints for these conditions are:

x1 + x2 ≥ 12000

x1 ≤ 8000

x2 ≥ 6000

5% of the toddlers in a preschool class drink water with their lunch. How many toddlers are in the class if 3 drink water with t

OLga [1]

Answer:

There are 60 toddlers in the preschool class

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Percentage of the toddlers in a preschool class drink water with their lunch = 5

Number of the toddlers in a preschool class drink water with their lunch = 3

2. How many toddlers are in the class?

We'll solve the question, using the Direct Rule of Three, this way:

Percentage Toddlers

5 3

100 x

*******************************

5x = 3 *100

5x = 300

x = 300/5

x = 60
