In the parallelogram DEFG, DH=x+1, HF=3y, GH=3x-4, and HE=5y+1. Find the values of x and y. The diagram is not drawn to scale.

RideAnS [48]

Answer:

Step-by-step explanation:

Given: In parallelogram DEFG,

DH = x + 1

HF = 3y

GH = 3x - 4

and HE = 5y + 1

Solution: Since, DH,HF, GH and HE represents the diagonals of the parallelogram and we know that the diagonals of the parallelogram bisect each other, therefore

x+1=3y (1)

3x-4=5y+1 (2)

Multiply equation (1) with 3 and then subtract equation (2) from it, we get

3x+3-3x+4=9y-5y-1

7=4y-1

y=2

Substituting the value of y=2 in equation (1), we get

x+1=3(2)

x=5

Therefore, the value of x and y are 5 and 2 respectively.

The monthly revenue of a certain company is given by R 820p-7p, where p is the price in dollars of the product the company manuf

The revenue will be 12,000 when the price of the product is $100

Given :

The monthly revenue of a certain company

$R=820p-7p^2$

We need to find out p when Revenue R is 12000

Lets replace R with 12000 and solve for p

$12000=820p-7p^2\\820p-7p^2=12000\\-7p^2+820p-12000=0$

Apply quadratic formula

$p=\frac{-820\pm \sqrt{820^2-4\left(-7\right)\left(-12000\right)}}{2\left(-7\right)}\\p=\frac{-820\pm \:580}{2\left(-7\right)}\\p=\frac{-820+580}{2\left(-7\right)},\:p=\frac{-820-580}{2\left(-7\right)}\\p=\frac{120}{7},\:p=100$

Given that price must be greater than 50

So the revenue will be 12000 when the price of the product is $100
