Answer: $0.36

Step-by-step explanation:

Given : You buy butter for $3.31 a pound.

i.e. cost of 1 pound of butter = $3.31

Also, 1 pound = 16 oz

Using UNITARY METHOD ,

1 oz = \dfrac{1}{16}\text{ pound}=0.0625\ oz

i.e. cost of 1 oz of butter = 0.0625 x  cost of 1 pound of butter

0.0625 x $3.31 =$ 0.206875    ≈ $0.21

One portion of the onion compote requires 1.7 oz of butter.

The cost of 1.7 oz of butter = 1.7 x cost of 1 oz of butter

1.7 x $ 0.21= $0.357≈ $0.36   [Rounded to the nearest cent]

Hence, the butter for one portion costs $0.36  .

What are the discontinuity and zero of the function f(x) = quantity x squared plus 6 x plus 8 end quantity over quantity x plus
Tcecarenko [31]

Answer:

Discontinuity at (-4,-2), zero at (-2,0).

Step-by-step explanation:

We are given that a function

f(x)=\frac{x^2+6x+8}{x+4}

We have to find the discontinuity and zero of the given function.

Discontinuity: It is that point where the function is not defined.

It makes the function infinite.

f(x)=\frac{x^2+4x+2x+8}{x+4}

f(x)=\frac{(x+4)(x+2)}{x+4}

When x=-4 then

f(-4)=\frac{0}{0} It is indeterminate form

Function is not defined

After cancel out x+4 in numerator and denominator  then we get

f(x)=x+2

Substitute x=-4

f(-4)=-4+2=-2

Therefore, the point of discontinuity is (-4,-2).

Zero: The zero of the function is that number when substitute it in the given function then the function becomes zero.

When substitute x=-2

Then , f(0)=-2+2=0

The function is zero at (-2,0).

Hence, option C is true.

Jim is enclosing a rectangular garden with 170 feet of fencing. The length of the garden is 10 feet more than twice it’s width,
Darina [25.2K]

Answer:

1,500\ ft^2

Step-by-step explanation:

Let

L ----> the length of the rectangular garden in feet

w ---> the width of  the rectangular garden in feet

step 1

Find the width

we know that

The perimeter of the rectangular garden is

P=2(L+W)

P=170\ ft

so

170=2(L+W)

Simplify

85=(L+W) ----> equation A

L=2W+10 ----> equation B

substitute equation B in equation A and solve for W

85=(2W+10+W)

85-10=3W

3W=75

W=25\ ft

Find the value of L

L=2(25)+10=60\ ft

step 2

Find the area

we know that

The area of the rectangular garden is

A=(LW)

substitute the values

A=(60)(25)=1,500\ ft^2
