Answer:
49
Step-by-step explanation:
Let be the unknown number. Twice means times 2. So, the mathematical sentence should be .
Divide both sides by 2.
To remove the radical symbol, raise both sides to the second power.
Thus, the answer is 49. Twice the square root of 49 is equal to 14.

Answer:
1.The correct answers here are the options A and C.
Under the United States Constitution, the powers that the states possess are those that are not given to federal government and those that are not prohibited by the Constitution itself. This is clearly seen here in the 10th Amendment. The states are free to set forth any laws that are constitutional so this does not mean any powers people want.
2.The correct answer here is the option A.
John C. Calhoun believed as did some other prominent politicians that nullification of federal laws was justified as the Constitution does not expressly give Congress the right to control states. But nullification is actually not legal and not true because of the Supremacy Clause that states that the Constitution and the federal laws created in accordance with it are the supreme law of the land. Also, Article III of the Constitution states that it is the federal judiciary that has the final say in the constitutionality of a law.
3.The correct answer here is the option A.
When the citizens of the United States think about the Constitution they mainly think about the Constitution of the United States. But before the colonies came together to create the Union they already created their own individual constitutions and entered the Union as free states. But these have been changed after the establishment of the Union in order to more reflect the Constitution of the United States.
The simplified form of this expression is <u>28 + 10i </u>
<h3>This question is an expression of imaginary numbers</h3>
Imaginary numbers are numbers that are composed of a real number and an imaginary part.
< To resolve this issue, let's remove the first parenthesis:
(3i + 4) - i + 4(6 + 2i)
3i + 4 - i + 4(6 + 2i)
< In the second parentheses, let's apply the distributive property:
3i + 4 - i + 4(6 + 2i)
3i + 4 - i + 4 . 6 + 4 . 2i
3i + 4 - i + 24 + 8i
< Finally, let's just sum the like terms, along with the real terms:
3i + 4 - i + 24 + 8i
10i + 4 + 24
10i + 28
<u>28 + 10i</u>
Therefore, the correct value will be <u>28 + 10i</u>
We know that
the equation of a vertical parabola in vertex form
y=a*(x-h)²+k
(h,k)------> (0,5)
y=a*(x-0)²+5
y=a*x²+5
substitute the point (2,9) in the equation
9=a*(2)²+5------> 9=4*a+5-------> 4*a=9-5-----> 4*a=4-----> a=1
the equation of the vertical parabola is
y=x²+5
the equation of a horizontal parabola in vertex form
x=a*(y-k)²+h
(h,k)------> (0,5)
x=a*(y-5)²+0
x=a*(y-5)²
substitute the point (2,9) in the equation
2=a*(9-5)²------> 2=16*a------> a=1/8
the equation of the horizontal parabola is
x=(1/8)*(y-5)²
the answer isthe equation of the vertical parabola is y=x²+5
the equation of the horizontal parabola is x=(1/8)*(y-5)²

Answer:
51+x-5+y-6=180
x+y=180-51+5+6
X+y=140
Answer x=77 y=63
(those 2 lines with the arrows are perpendicular so their angles are the same 72° and (x-5)=77-5= 72°)
