Hello!

We must use a certain formula to find the circumference of anything circular.

The formula is:

C = 2 × pi × r

We know that pi = 3.14 approximately and the radius is 3 feet.

Substitute:

C = 2 × 3.14 × 3

C = 6.28 × 3

C = 18.84 ft

ANSWER:

The circumference of the circular rug is 18.84 ft. (Last option)

Evaluate the profit function at each vertex. P = 0.04x + 0.05y + 0.06(16 – x – y) (8, 1) P = (14, 1) P = (3, 6) P = (5, 10) P =
VARVARA [1.3K]
The given function is:
P = 0.04x + 0.05y + 0.06(16-x-y)

To get the function at each vertex, all you have to do is substitute with the given x and y values in the above equation and get the corresponding value of P as follows:
1- For (8,1):
P = 0.04x + 0.05y + 0.06(16-x-y)
P = 0.04(8) + 0.05(1) + 0.06(16-8-1)
P = 0.79

2- For (14,1):
P = 0.04x + 0.05y + 0.06(16-x-y)
P = 0.04(14) + 0.05(1) + 0.06(16-14-1)
P = 0.67

3- For (3,6):
P = 0.04x + 0.05y + 0.06(16-x-y)
P = 0.04(3) + 0.05(6) + 0.06(16-3-6)
P = 0.84

4- For (5,10):
P = 0.04x + 0.05y + 0.06(16-x-y)
P = 0.04(5) + 0.05(10) + 0.06(16-5-10)
P = 0.76

Hope this helps :)

What is the absolute value of the complex number Negative 4 minus StartRoot 2 EndRoot i?
IRINA_888 [86]

Answer:

3\sqrt{2}

Step-by-step explanation:

For the complex number a+bi, the absolute value is \sqrt{a^2+b^2}

Given the complex number -4-\sqrt{2}i. For this complex number,

a=-4\\ \\b=-\sqrt{2},

then the absolute value is

\sqrt{(-4)^2+(-\sqrt{2})^2}=\sqrt{16+2}=\sqrt{18}=3\sqrt{2}

Cost per pound       
Unit Cost * 16oz     $5.60 per lb                          $4.80 per lb

The blueberries in the farmer's market costs less than the blueberries from the grocery store. 

One pound of blueberries from the farmer's market is cheaper by $0.80 than the blueberries from the grocery store. ($5.60 - $4.80 = $0.80)
