Which is equivalent to (−2m + 5n)2, and what type of special product is it4m2 + 25n2; a perfect square trinomial 4m2 + 25n2; the difference of squares 4m2 − 20mn + 25n2; a perfect square trinomial 4m2 − 20mn + 25n2; the difference of squares

Answers

We'll calculate the product:

$(-2m+5n)^2=(-2m+5n)(-2m+5n)\n\n (-2m+5n)^2=(-2m)\cdot(-2m+5n)+(5n)(-2m+5n)\n\n (-2m+5n)^2=[(-2m)\cdot(-2m)+(-2m)\cdot(5n)]+[(5n)\cdot(-2m)+(5n)\cdot(5n)]\n\n (-2m+5n)^2=4m^2-10mn-10mn+25n^2\n\n (-2m+5n)^2=4m^2-20mn+25n^2$

So, the answer is:

$4m^2-20mn+25n^2,~\text{a perferct square trinomial.}$

The concept of the square is applied that is the multiplication of the term itself two times.

The equivalent function of $\rm (-2m + 5n)^2$ is $\rm 4m^2 - 20mn + 25n^2$ .

What is an equivalent function?

The equivalent is the functions that are in different forms but are equal to the samevalue.

Given

(-2m + 5n)² is a function.

To find

The equivalent function of (-2m + 5n)².

We know that this can be written as

(-2m + 5n) x (-2m + 5n)

On multiply, we have

$\rm (-2m + 5n)(-2m + 5n)\n\n-2m(-2m + 5n) + 5n(-2m + 5n)\n\n(-2m)^2 - 10mn -10mn + (5n)^2\n\n4m^2 - 20mn + 25n^2$

Thus, the equivalent function of (-2m + 5n)² is 4m² - 20mn + 25n².

A particular beach is eroding at a rate of 4 centimeters per year. A realtor converts this rate to millimeters per day. Which expression, when evaluated, results in the correct units and numerical value?

Answers

Answer:

0.11mm/day

Step-by-step explanation:

We are given that

A particular is eroding at the rate=4 cm/ year

We have to convert this rate on milimeters per day.

We know that

1 year=365 days

1 cm=10 mm

Rate= $(4* 10)/(365)$

Rate= $0.1096=0.11 mm/day$

Answer:0.11 mm/day

4 cm/year * 10mm/cm * 1year/365day ≈ 0.11 mm/day

How is the measurement 0.000 065 cm written in scientific notation?

Answers

We have to express 0.000065 cm in scientific notation.

Scientific notation is a mathematical expression used to represent a decimal number between 1 and 10 multiplied by ten, so we can write large numbers using less digits.

Consider 0.000065 cm = $6.5 * 10^-5$ cm

Therefore, $6.5 * 10^-5$ cm is the scientific notation for the given number 0.000065 cm.

Answer:

6.5 x 10^-5 cm
