A company can send a maximum of 40 workers to complete a
task. The manager needs to limit the total cost of the workers
within $1000. He needs to pay $30 and $20 to each female
and male worker for this task respectively. Write a system of
inequalities to express this situation. What is the least possible
number of male workers the manager should send to meet the
requirements?
male workers

Answers

Answer:

Step-by-step explanation:

For the sake of the problem, let's make female workers "x" and male workers "y".

x+y<40 This equation shows that the total number of workers has a max of 40.

30x+20y<1,000 This equation shows that the total cost the manager pays ($30 to each woman, $20 to each man) has a max of $1,000.

Now you can solve for x and y.

X+y<40

-y -y

X<-y+40

Substitute -y+40 in for X in the second equation

30(-y+40)+20y<1,000

-30y+1200+20y<1,000 Distribute

-10y+1,200<1,000 Combine like terms

-10y<-200 Subtract 1,200

y>20 Divide by -10; flip the sign

Since y>20, and y=male workers, you now know that the minimum

number of male workers he should send is 20

The midpoint of AB is M (1, 3). If the coordinates of A are (-1, 5), what are the coordinates of B?

Answers

Answer:

(3, 1)

Step-by-step explanation:

Let the coordinates of B be (x, y)

Since, M is the midpoint of AB.

Therefore, by mid point formula:

[tex]1 = \frac{ - 1 + x}{2}, \: \: \: 3 = \frac{5 + y}{2} \\ \\ 2 = - 1 + x, \: \: \: 6 = 5 + y \\ \\ 2 + 1 = x, \: \: \: 6 - 5 = y \\ \\ 3 = x, \: \: \: 1 = y \\ \\ x = 3, \: \: \: y = 1 \\ \\ B = (3, \: \: 1)[/tex]

Yesterday morning at 8 a.m. the temperature was -14°F. At noon it was 10 degrees warmer. The temperature increase between noon and and 4 p.m. was twice the temperature increase between 8 a.m. and noon. What was the temperature at 4 p.m?

Answers

Answer:

16°

Step-by-step explanation:

so 10 degrees warmer from 8 to noon

-14°+10°= -4°

so at noon, it was -4°

but then from noon to 4 pm, the temp change was twice that

10° x 2= 20°

-4° + 20° = 16°

temp at 4 pm was 16°

If the value of a is 8 in F(x)=ax^2 What does the graph look like

Answers

The graph would be more compressed looking, rather than open/stretched.

So a general understanding of what ax^2 can help tremendously with these types of questions. From what I’ve learned in school, this is simply a translation from the original equation. The original equation would be considered the base for of this equation without ANY transformations.

The original equation in this case would be y=ax^2. When you only have this equation, it should be a simple parabola that goes up to 1 then 4 then 16... etc. When the a value is changed though, it changes according to our square values (notice how the original equation is only going by squares) so instead of starts at 1, we are starting at 8 because 1^2 is 1 then MULTIPLIED by 8 would be 8. I’ll use Desmos to explain.

From the graph, it shows how much more squished together because of how high each number goes up due to the multiplier value of a (or 8 in this case).
