Solve the equation by completing the square.
x^2 + 10x= -81
Answer:
x =-5± 2i sqrt(14)
Step-by-step explanation:
x^2 + 10x= -81
Take the coefficient of x and divide by 2
10/2 = 5
Square it
5^2 =25
add to each side
x^2 + 10x+25 = -81+25
( x+5) ^2 = -56
Take the square root of each side
sqrt(( x+5) ^2) =± sqrt(-56)
x+5 = ± sqrt(-1) sqrt(4*14)
x+5 =± i sqrt(4)sqrt(14)
x+5 =± i 2 sqrt(14)
Subtract 5 from each side
x+5-5 =-5± i 2 sqrt(14)
x =-5± 2i sqrt(14)

find the measures of arc FBD
Answer:
Option (4)
Step-by-step explanation:
[tex]m(\widehat{FC})[/tex] = 180° [FC is the diameter]
[tex]m(\widehat{FC})=m(\widehat{FB})+m(\widehat{BC})[/tex]
180° = 125° + [tex]m(\widehat{BC})[/tex]
[tex]m(\widehat{BC})=180-125[/tex] = 55°
[tex]m(\widehat{FBD})=360-m(\widehat{FED})[/tex]
[tex]=360-[m(\widehat{FE})+m(\widehat{ED})][/tex]
[tex]=360-[m(\widehat{BC})+m(\widehat{ED})][/tex] [Since [tex]m(\widehat{FE})=m(\widehat{BC})[/tex] arcs created by vertical angles]
[tex]=360-(55+56)[/tex]
= 249°
Therefore, Option (4) will be the answer.

A. x=c/3
B. x=3/c
C. x=11/c
D. x=c/11
Answer:
x = 11/c
Step-by-step explanation:
Solve for x:
c x - 4 = 7
Hint: | Isolate terms with x to the left-hand side.
Add 4 to both sides:
c x = 11
Hint: | Solve for x.
Divide both sides by c:

Write 2 x 10^3 in standard notation.
Answer:
2000
Hope this helps :)
Step-by-step explanation:
Since the exponent of the scientific notation is positive, move the decimal point 3 places to the right.
The standard notation of the expression is 2 x 10³ is 2000.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
2 x 10³
Standard notation means writing an expression without any base and exponents.
Now,
10³ can be written as 1000.
So,
2 x 10³
= 2 x 1000
= 2000
Thus,
The standard notation is 2000.

HE is 1/3 the length of HG , HE=x-3 and HG=4x-15 find HE
Answer:
x=24
Step-by-step explanation:
HE= 1/3(HG)
x-3=1/3(4x-15)
3x-9=4x-15
-x=-24
x=24
Answer:
HE=3
Step-by-step explanation:
Equations
With the data provided, we can set up an equation. Then we need to solve the equation. Finally, we use the just-found value of x to calculate HE.
Data:
HE=1/3 HG
HE=x-3
HG=4x-15
Replacing the last two equations in the first:
x-3=1/3(4x-15)
Multiply both sides by 3:
3(x-3)=4x-15
Operate:
3x-9=4x-15
Moving x's to the left and numbers to the right:
3x-4x=-15+9
Joining like terms:
-x=-6
Multiply by -1:
x=6
Since HE= x-3:
HE=6-3
HE=3

Duke Energy reported that the cost of electricity for an efficient home in a particular neighborhood of Cincinnati, Ohio was $104 per month (Home Energy Report, Duke Energy, March, 2012). A researcher believes that the cost of electricity for a comparable neighborhood in Chicago, Illinois is higher. A sample of homes in this Chicago neighborhood will be taken and the sample mean monthly cost of electricity will be used to test the following null and alternative hypotheses.
Assume the sample data lead to rejection of the null hypothesis.
What would be your conclusion about the cost of electricity in the Chicago neighborhood?
The input in the box below will not be graded, but may be reviewed and considered by your instructor. What is the Type I error in this situation?
The Type 1 error in this situation What are the consequences of making this error?
The input in the box below will not be graded, but may be reviewed and considered by your instructor. What is the Type II error in this situation?
Answer:
When the null hypothesis is rejected
The conclusion is that there is enough evidence to support the claim of the researcher
When a type I error occurs
The consequences is that the conclusion that there is enough evidence to support the claim of the researcher is actually incorrect
When a type II error occurs
The consequences is that the conclusion that there is enough evidence to support the claim of the researcher is actually correct
Step-by-step explanation:
From the question we are told that
The cost of electricity per month is [tex]\mu = \$104[/tex]
The null hypothesis is [tex]H_o : \mu = \$104[/tex]
The alternative hypothesis is [tex]H_o : \mu > \$104[/tex]
Generally if the null hypothesis is rejected then the conclusion would be that there is enough evidence to support the claim of the researcher
Generally a Type I error is a an error that occurs when the null hypothesis is incorrectly rejected
So in the case of this question the consequence of making this type of error is that the conclusion that there is enough evidence to support the claim of the researcher is actually incorrect
Generally a Type II error is an error that occurs when the null hypothesis is incorrectly not rejected
So in the case of this question the consequence of making this type of
error is that the conclusion that there is enough evidence to support the claim of the researcher is actually correct
