Mathematics

The area of this parallelogram is the sum of the area of triangle DAE , area of triangle BCF and area of rectangle DEBF

Area of trianle DAE = 1/2 * base * height = 1/2 * AE * DE = 1/2 * 4 * 7 = 14 m²

Area of trianle BCF = 1/2 * base * height = 1/2 * CF * BF = 1/2 * 4 * 7 = 14 m²

Area of rectangle DEBF = length * width = FD * DE = 8 * 7 = 56 m²

Therefore, Area of the parallelogram = 14 + 14 + 56 = 84 m²

Find the absolute minimum and absolute maximum of f(x,y)=14−7x+10y f(x,y)=14−7x+10y on the closed triangular region with vertice
Black_prince [1.1K]

Answer:

Maximum value of f(x,y) at (10,13)=74

Minimum value of f(x,y) at (10,0)=-56

Step-by-step explanation:

We are given that

f(x,y)=14-7x+10y

Vertices are (0,0),(10,0) and (10,13)

Substitute x=0 and y=0

f(0,0)=14-0+0=14

Substitute x=10 and y=0

f(10,0)=14-7(10)+10(0)=14-70=-56

Substitute x=10 and y=13

f(10,13)=14-7(10)+10(13)=14-70+130=74

Maximum value of f(x,y) at (10,13)=74

Minimum value of f(x,y) at (10,0)=-56

Four times the sum of half a number and 6 is 48
katrin [286]

Answer:

<h3>The number is 12</h3>

Step-by-step explanation:

Let the number be x

Half a number is written as 1/2x

So we have

Four times the sum of half a number and 6 is 48 is written as

4( \frac{1}{2} x + 6) = 48 \\ 2x + 24 = 48 \\ 2x = 48 - 24 \\ 2x = 24

Divide both sides by 2

That's

\frac{2x}{2}  =  \frac{24}{2}

We have the final answer as

<h3>x = 12</h3>

Hope this helps you

Can you tell my friend this is right so he can stop saying it is wrong
Natasha2012 [34]
Your graph is correct.
You start with point (0, 40). On day 0, you have 40 T-shirts.
Each day that passes, you have 5 shirts fewer. (1, 35) means on day 1, you have 35 shirts left. Each day that passes, there are 5 fewer shirts. On the 8th day, there are no shirts left. That is point (8, 0).

Good job!
