Find the distance between the points (-10,-7) and (2,9).

soldier1979 [14.2K]

20 (units)

Distance formula is:

Sqrt of (x-x1)^2+(y-y1)^2

So define which coordinate is (x,y) and what (x1,y1)

I’m going to define (-10,-7) as (x,y) and (2,9) as (x1,y1)

So plug in your variables!

Sqrt(-10-2)^2+(-7-9)^2

Sqrt-12^2+-16^2

Sqrt144+256

Sqrt400

So sqrt of 400 is 20! :))

Ket [755]

Answer:

Number of terms: 2

Degree: 1

Step-by-step explanation:

✔️A term can either be a coefficient with a variable, a variable, or a constant.

In the polynomial given, 10y + 2, there are two terms:

First term is a coefficient with a variable = 10y

Second term is a constant = 2

The two terms are: 10y and 2

✔️Degree of a polynomial is the highest exponents possessed by any of its term.

10y has an exponent of 1.

The degree of the polynomial therefore will be 1

A new crew of painters can paint a small apartment in 12 hours and experience crew can paint a small apartment in six hours how

dalvyx [7]

Answer:

The new crew and the experience crew working together can paint the apartment in 4 hours.

Step-by-step explanation:

Given:

Time taken by new crew of painters to paint an apartment = 12 hours

Time taken by experience crew of painters to paint an apartment = 6 hours

To find the time taken by them to paint the apartment working together.

Solution:

Using unitary method to determine their 1 hour work.

In 12 hours the new crew can paint = 1 apartment

So,in 1 hours the new crew can paint = $\frac{1}{12}$ of the apartment

In 6 hours the experience crew can paint = 1 apartment

So,in 1 hour the experience crew can paint = $\frac{1}{6}$ of the apartment

Now, the new crew and the experience crew are working together.

So, in 1 hour, they can paint :

⇒ $\frac{1}{12}+\frac{1}{6}$

Taking LCD = 12, we will add fraction.

⇒ $\frac{1}{12}+\frac{2}{12}$

⇒ $\frac{3}{12}$

Simplifying fraction we have:

⇒ $\frac{1}{4}$ of an apartment

Again using unitary method to determine the time taken by them working together to paint the whole apartment.

They can paint $\frac{1}{4}$ of an apartment in 1 hour.

To paint 1 apartment they will take = $\frac{1}{\frac{1}{4}}=4$ hours

Thus, the new crew and the experience crew working together can paint the apartment in 4 hours.
