Use distance formula

  = sqrt ( (y2-y1)^2 + (x2-x1)^2)   where the 2 points are (x1,y1) and (x2,y2).

so answer is  sqrt ((9-8)^2 + ((-3--6)^2)  = sqrt (1 + 9) = sqrt 10

answer is sqrt 10 or 3.16 to nearest hundredth.

Noah thinks the answers to these two questions will be the same. This year, a herd of bison had a 10% increase in population. If
Shalnov [3]

The answer to these two questions are not the same. We don't agree with Noah.

Reason:

Let's start with the first question.

1. Given: rate = 10% increase, base/original number = 550 bison

10% of 550 is:

.10\times550bison=55bison

10% of 550 is 55. Hence, there is an increase of 55 bison this year. This year, there are 550 + 55 = 605 bison in the herd.

2. Given: rate = 10% decrease, percentage/final number = 550 bison

Applying the concept of Percentage = Base x Rate, we can get the Base or the original number of bison before the decrease by dividing Percentage over Rate.

\text{Base}=\frac{\text{Percentage}}{\text{Rate}}

Filling in the formula with the given values in question 2, we have:

\text{Base}=\frac{550}{1-.10}=\frac{550}{.90}=611.11\approx611bison

Last year, there were 611 bison.

As we can see, the answer for number 1 is 605 bison while the answer for the number 2 is 611 bison. The answer of the two questions are not the same.

Why is -9an acceptable answer to the equation x2=81 ?
Arte-miy333 [17]

Answer:

X=9 or x=-9

Step-by-step explanation:

X^2=81

Can be written as

x^2-81=0

Factorize by the property:

a^2-b^2=(a-b)(a+b)

So the expression becomes:

(x-9)(x+9)=0

Therefore, either x-9=0or x+9=0

Then the solutions are x=9 or x=-9
