The problem is "estimate the number of pints in 455 fluid ounces.Explain your work"

larisa [96]

8 fluid oz=1 cup
2 cup=1 pint
so

16 fluid oz=1pint

so just divide 455 by 16 or estimate by rounding 16 to 15 and 455 to 450
we know that 45/15=3 so the andwer is 450/15=30

about 30 pints

What is the parent function for the following f(x) = (x-2) (x-1)

Taya2010 [7]

Answer:

The parent function of f(x) = (x-2) (x-1) is $P(x) = x^2- 3 x + 2$ .

Step-by-step explanation:

Here, f(x) = (x-2) (x-1)

Now, parent function of a given function is the function, which is PRODUCT OF ALL IT S FACTORS.

Now, here, f(x) has two factors ( x- 2) and ( x-1)

So, the parent function p(x) of f(x) is given as the product of both the factors.

So, we get:

$P(x) = (x-2) (x-1) \\= x( x-1) -2(x-1)\\=x^2 - x -2x + 2\\= x^2- 3 x + 2\\\implies P(x) = x^2- 3 x + 2$

Hence, here the parent function of f(x) = (x-2) (x-1) is $P(x) = x^2- 3 x + 2$ .

Ken's landscape gardening business creates odd-shaped lawns that include semicircles. Find the area of this semicircular section

salantis [7]

Answer:

Area of semicircular lawn is 9.82 square meter.

Step-by-step explanation:

Given:

Diameter of the semicircle = 5 m

So we will find the radius.

Radius is half of the diameter.

Radius $r=\frac{5}{2}=2.5\ m$

We need to find the area of the lawn.

Solution:

Now we know that;

Area of semicircle is half times π times square of the radius.

framing in equation form we get;

Area of semicircular lawn = $\frac12\pi r^2=\frac12\times\frac{22}{7}\times 2.5\times 2.5=9.82\ m^2$

Hence Area of semicircular lawn is 9.82 square meter.
