Answer:
12.
Step-by-step explanation:
The side length = sqrt 9 = 3
so the perimeter = 4*3 = 12.
Hi there!

I believe your answer is:
12 units.

Here’s why:
The formula for area of a square is:
[tex]A=s^2\\\\\boxed{\text{Key:}}\\\\s-\text{Side length given.}[/tex]
⸻⸻⸻⸻
We are given the area of the square, 9. To find the side length of the square, required to get the perimeter, we would have to take the square root of 9.Recall that the area of a square is the square of it's side length. [tex](s^2)[/tex]⸻⸻⸻⸻
[tex]\boxed{\text{Finding the side length of the square:}}\\\\\rightarrow S=9\\\\\sqrt{9}=3\\\\\rightarrow S=\boxed{3}^2[/tex]
⸻⸻⸻⸻
The side length of the square is 3 units.
⸻⸻⸻⸻
The formula for perimeter of a square is:
[tex]P=4(s)\\\\\boxed{\text{Key:}}\\\\s-\text{Side Length}[/tex]
⸻⸻⸻⸻
We have previously calculated the side length of the square, which is 3.We would have to multiply 3 by 4 to get the perimeter.Recall that the perimeter of a square is 4 times the side length. [tex]4(s)[/tex].
⸻⸻⸻⸻
[tex]\boxed{\text{Finding the perimeter of a square:}}\\\\P=4(3)\\\\\boxed{P=12}[/tex]
⸻⸻⸻⸻
The perimeter of the square is 12 units.

what is the distance between the first integer that is less than square root 40 amd the first integer that is greater than square root of 125?
Answer:
6
Step-by-step explanation:
[tex]\sqrt{40} = 6.32 so 6 \\\sqrt{125} = 11.18 so 12\\12 - 6 = 6[/tex]
A radioactive substance with initial value of 800g decays according to the exponential model A= 800e^(kt). After 10 years, only 400g of the substance remains. Find the value of k. Round your answer to the nearest thousandth. NO LINKS!!!!
Answer:
k ≈ - 0.069
Step-by-step explanation:
Given
A = 800 [tex]e^{kt}[/tex]
Substitute A = 400 and t = 10 into the equation
400 = 800 [tex]e^{10k}[/tex] ( divide both sides by 800 )
0.5 = [tex]e^{10k}[/tex] ( take the ln of both sides )
ln [tex]e^{10k}[/tex] = ln0.5
10k lne = ln0.5 [ lne = 1 ]
10k = ln 0.5 ( divide both sides by 10 )
k = [tex]\frac{ln0.5}{10}[/tex] ≈ 0.069 ( to the nearest thousandth )
Answer:
Step-by-step explanation:
400 = 800 * e^(k*t)
What are the units of t? I'm taking it as years.
Divide by 800
400/800 = e^(k*10)
1/2 = e^(k*10)
ln(1/2) = ln(e)^(k*10)
ln(1/2) = k*10 * ln(e)
ln(e) = 1
-0.69314 = k*10
-0.069314 = k
Check
A = 800 e^(-0.069314*10)
A = 800 e^(-0.69314)
A = 800 * 0.50000359
A = 400.0028722
Which is close enough to 400

Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. We wish to compare the means of two populations using paired observations. Suppose that d3.125, 2.911, and n8, and that you wish to test the hypothesis below at the 10% level of significance. What decision rule would you use? : 0 against : 0
Answer:
Decision Rule
The critical region for one tailed test with 7 d.f is t > 1.415 for
H0 : ud ≤ 0 against the claim Ha: ud > 0
Step-by-step explanation:
The data given is
Population mean = ud= 0
Sample difference mean = d`= 3.125
Sample difference standard deviation = sd= 2.911
Sample size= n= 8
Formulate the null and alternate hypotheses as
H0 : ud ≤ 0 against the claim Ha: ud>0
The significance level ∝= 0.1
The degrees of freedom = n-1 = 8-1 = 7
The critical region for one tailed test with 7 d.f is t > 1.415
The test statistic is
t= d`- ud/ sd/ √n
Putting the values
t= 3.125-0 / 2.911/√8
t= 3.125/1.0292
t= 3.036
since the calculated value of t falls in the critical region we reject the null hypothesis .
The triangle shown below has an area of 20 units squared. Find the missing side if the height is 8
Answer:
5 unitsStep-by-step explanation:
Lets keep the missing side as x
And we also know that the area of Triangle is,
[tex] \frac{1}{2} bh[/tex]
So taking this into consideration we can write a linear equation like this,
[tex] \frac{1}{2} bh = 20[/tex]
Where height is 8,
[tex] \frac{1}{2} \times b \times 8 = 20 \\ 4 \times b = 20 \\ b = \frac{20}{4} \\ b = 5[/tex]
So therefore the missing side is 5
Jovi distributed 3(n+2) and got 3 x n + 3 x 6 is his answer correct
Answer:
Step-by-step explanation:
since 3 is outside the parenthesis (n + 2) you multiply the 3 by the n and the 2 and
3n + 6
next subtract the 6 and add the 6 to the other side
3n - 6 = 6
3n = 6
n = 2

(b) What are the equations of the circle in graphing form and in general form? Show your work.
Answer:
Center = (-1, 1)
Radius = 3
Graphing form
(x + 1)² + (y - 1)² = 3²
General form
x² + y² + 2x - 2y - 7 = 0
Step-by-step explanation:
Center = (-1, 1)
Radius = 3
Graphing form
(x + 1)² + (y - 1)² = 3²
General form \Expand graphing form\
(x² + 2x + 1) + (y² - 2y + 1) - 9 = 0
Rearrange
x² + y² + 2x - 2y - 7 = 0
