To calculate the perimeter of a polygon, just add all of the sides together.
In this case, take 4 and multiply it by 8 (since there are 8 sides)
4km x 8 = 32km
What's the slope of the line?
Answer:
3
Step-by-step explanation:
lets just take two random points that are on the line ( it doesn't have to be a specific point)
(-2,0) and (-1 , 3) cuz why not
we need to find the difference of both the y coordinates divided by the difference of both the x coordinates
0-3 / -2 - (-1)
-3 / -1
3/1 = 3
Answer:
choose two random points of the line and....
slope of line=3

What is probability?probability is the ratio of the number of favorable outcomes and the total number of possible outcomes. The chance that a particular event (or set of events) will occur expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%.

A biased estimator is one that deviates from the true population value. A biased sample can still be useful if the nature of the bias and how much of a bias exists is known.
An unbiased estimator is when a value from a sample is the same as the actual value of a population parameter.
The sample is not chosen at random, the inherent bias in convenience sampling means that the sample is unlikely to be representative of the population being studied. This undermines your ability to make generalizations from your sample to the population you are studying.
Therefore, the sample of the assigned reading likely to be biased and convenience sample.

Step-by-step explanation:
Use the distance formula:
d = [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]
Points of the diagonal: (-2, -2) and (2, 4)
d = [tex]\sqrt{(2-(-2))^2+(4-(-2))^2}[/tex]
d = [tex]\sqrt{(2+2)^2+(4+2)^2}[/tex]
d = [tex]\sqrt{(4)^2+(6)^2}[/tex]

Step-by-step explanation:

and I know, you're thinking..... what's the deal with all the letters... how do I add those up? :D ..... you are right... you can't add letters... the letters are just the variables... or places holders for numbers... you can put many different numbers into each of them but... the relationship.... which is made by the equal sign.. must hold true for any numbers you put in for the variables.... sooo.. like this.. for your particular answer
[tex]19^{2}[/tex] = [tex]10^{2}[/tex] + [tex]y^{2}[/tex]
( notice I've put in a " y " , where there is a B in the formula above but that's just a letter... again.. which is just a variable... the place holder for a number... soooo..... )
361 = 100 + [tex]y^{2}[/tex] ( subtract 100 from each side of the " = " )
261 = [tex]y^{2}[/tex] ( to undo the square on the wye... square root both sides)[tex]\sqrt{261}[/tex] = y
my calculator tells me that [tex]\sqrt{261}[/tex] = 16.15549442

The product of two consecutive numbers is 72. Use a quadratic equation to find the two sets of numbers.
Given:
The product of two consecutive numbers is 72.
To find:
The two numbers by using the quadratic equation.
Solution:
Let the two consecutive numbers are x and (x+1).
The product of two consecutive numbers is 72.
[tex]x(x+1)=72[/tex]
[tex]x^2+x-72=0[/tex]
Splitting the middle term, we get
[tex]x^2+9x-8x-72=0[/tex]
[tex]x(x+9)-8(x+9)=0[/tex]
[tex](x+9)(x-8)=0[/tex]
Using zero product property, we get
[tex]x+9=0[/tex] and [tex]x-8=0[/tex]
[tex]x=-9[/tex] and [tex]x=8[/tex]
If [tex]x=-9[/tex], then
[tex]x+1=-9+1[/tex]
[tex]x+1=-8[/tex]
If [tex]x=8[/tex], then
[tex]x+1=8+1[/tex]
[tex]x+1=9[/tex]
Therefore, the two consecutive numbers are either 8,9 or -9,-8.

A geometric sequence has an initial value of 2 and a common ratio of 3. Which formula would be more practical to use if you were looking find the value of the 19th number in the sequence?
Answer:
19th term = ar^18
19th term = 774,840,978
Step-by-step explanation:
First term, a = 2
Common ratio, r = 3
nth term of a geometric sequence = ar^(n-1)
19th term = ar^(19-1)
19th term = ar^18
= 2 × 3^18
= 2 × 387,420,489
= 774,840,978
19th term = 774,840,978

Which expression is equivalent to the given expression? 6ab/(a^0b^2)^4
Answer:
B
Step-by-step explanation:
[tex]x^{0} = 1\\\\\frac{x^{m}}{x^{n}}= \frac{1}{x^(n-m)}}, n >m\\\\\\\frac{6ab}{(a^{0}b^{2})^{4}}=\frac{6ab}{(1*b^{2})^{4}}\\\\=\frac{6ab}{b^{2*4}}\\\\=\frac{6ab}{b^{8}}\\\\=\frac{6a}{b^{8-1}}\\\\=\frac{6a}{b^{7}}[/tex]
The equivalent expression of 6ab/(a^0b^2)^4 is 6a/b^7
How to determine the equivalent expression?The expression is given as:
6ab/(a^0b^2)^4
Evaluate the exponent of 0
