Dennis stood on a 9 foot ladder to measure the sunflower. How much taller is the tallest sunflower than the ladder?

Shalnov [3]

Answer:

See Explanation

Step-by-step explanation:

Given

$Ladder = 9ft$

$Tallest\ Sunflower = x$

Required

How much taller is the tallest

To get this, we simply calculate the difference between the height of the tallest sunflower and the ladder.

i.e.

$Difference = Tallest\ Sunflower - Ladder$

$Difference = x - 9$

-----------------------------------------------------------------------------------------------------

If for instance, the tallest is 13ft, then it is 4ft taller.

Because:

$Difference = 13ft - 9ft$

$Difference = 4ft$

Which is the completely factored from of xy^3-x^3y

Oksanka [162]

Answer:

$xy(y+x)(y-x)$

Step-by-step explanation:

To factor the expression, remove the greatest common factor or GCF from each term. Both terms share in common xy. The expression becomes:

$xy^3-x^3y\\xy(y^2-x^2)$

What remains in the parenthesis is a different of perfect squares. Factor the difference of perfect squares into two binomials of the form (x+a)(x-a) where a is the square root of $(x^2-a^2)$ .

So the expression becomes:

$xy(y^2-x^2)\\xy(y+x)(y-x)$

A flying disc in the shape of a circle has a circumference of 8 inches. What is the radius of the flying disc.

mafiozo [28]

Answer:

Step-by-step explanation:

The formula for circumference is:

$C=2\pi r$

We know that the circumference is 8π inches. So, substitute 8π for C:

$8\pi =2\pi r$

Solve for r. Divide both sides by 2π. So:

$r=\frac{8\pi}{2\pi}=4$

Therefore, the radius is 4 inches.

Hence, our answer is A.
