Answer:
There are 5 planets visible without a telescope, Mercury, Venus, Mars, Jupiter, and Saturn (6 if you include Uranus for those with sharp eyes!). All of them plus Neptune move within 7 degrees of the ecliptic.
Venus. After the Moon, Venus is the brightest natural object in the night sky. It is both the Earth's closest neighbor in our Solar System and the planet most similar to Earth in size, gravity, and composition. We can't see the surface of Venus from Earth, because it is covered with thick clouds.

Rounding decimals 3.5691 thousandths
Explanation:
There's a 9 in the thousandths place. The next digit to the right is 1, which is not 5 or more. So we'll just drop that 1 and that's why the answer is 3.569
Answer:
3.569
Step-by-step explanation:
Rounding is the process of shortening a number to a certain number of digits by finding the closest number with the desired number of digits. When rounding, look one digit to the right of the desired decimal place. In this case, you want the thousandths place. The thousandths place is 3 digits after the decimal, so look at the number next to the 9, the 1. If the number is 5 or greater round up, if it is 4 or less round down. Therefore, 3.5691 should be rounded down to 3.569.
Other examples include,
4.8736 being rounded up to 4.874
6.3168 being rounded up to 6.317

PLEASE HELP ASAP Due in 1 day!!!
Question 1
Find(f+g)(x)
f(x)=4x−4 and g(x)=2x^2−3x
Question 2
Find(f−g)(x)
f(x)=2x^2−2 and g(x)=4x+1
Question 3
Find(h⋅g)(x)
h(x)=3x−3 and g(x)=x^2+3
Question 4
Find(f/g)(x)and state the domain restriction.
f(x)=x+4 and g(x)=x+6
Step-by-step explanation:
Q1 . (f+g)(x) = f(x) + g(x)
=4x-4 +2x^2 -3x
= 2x^2 + x -4
Q2. (f-g)(x) = f(x) - g(x)
= 2x^2−2 - (4x+1)
= 2x^2 -2 -4x -1
= 2x^2 - 4x -3
Q3. h(x)=3x−3 and g(x)=x^2+3
(h.g)(x) = h(x) × g(x)
= (3x-3) × (x^2 + 3)
=3x^3 -3x^2 + 9x -9
Q4.f(x)=x+4 and g(x)=x+6
(f/g)(x) = f(x) ÷ g(x)
= x+4 / x+6
the domain restriction is x>-6
x<-6
x doesn't equal (-6)
If the two function f(x) and g(x) are to be combined, use basic arithmetic rules,
(f + g)(x) = f(x) + g(x)
(f - g)(x) = f(x) - g(x)
[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]
(f . g)(x) = f(x) × g(x)
Question 1
f(x) = 4x - 4 and g(x) = 2x² - 3x
[tex](f+g)(x)=f(x)+g(x)[/tex]
Therefore, [tex](f+g)(x)=(4x-4)+(2x^2-3x)[/tex]
[tex]=2x^2+x-4[/tex]
Question 2
f(x) = 2x² - 2 and g(x) = 4x + 1
Since, (f - g)(x) = f(x) - g(x)
Therefore, (f - g)(x) = (2x² - 2) - (4x + 1)
= 2x² - 2 - 4x - 1
= 2x² - 4x - 3
Question 3
h(x) = 3x - 3 and g(x) = x² + 3
Since, (h - g)(x) = h(x) - g(x)
Therefore, (h - g)(x) = (3x - 3) - (x² + 3)
= 3x - 3 - x² - 3
= -x² + 3x - 6
Question 4
F(x) = x + 4 and g(x) = x + 6
Since, [tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]
Therefore, [tex](\frac{f}{g})(x)=\frac{x+4}{x+6}[/tex]

\lim _{x\to 0}\left(\frac{2x\ln \left(1+3x\right)+\sin \left(x\right)\tan \left(3x\right)-2x^3}{1-\cos \left(3x\right)}\right)
[tex]\displaystyle \lim_{x\to 0}\left(\frac{2x\ln \left(1+3x\right)+\sin \left(x\right)\tan \left(3x\right)-2x^3}{1-\cos \left(3x\right)}\right)[/tex]
Both the numerator and denominator approach 0, so this is a candidate for applying L'Hopital's rule. Doing so gives
[tex]\displaystyle \lim_{x\to 0}\left(2\ln(1+3x)+\dfrac{6x}{1+3x}+\cos(x)\tan(3x)+3\sin(x)\sec^2(x)-6x^2}{3\sin(3x)}\right)[/tex]
This again gives an indeterminate form 0/0, but no need to use L'Hopital's rule again just yet. Split up the limit as
[tex]\displaystyle \lim_{x\to0}\frac{2\ln(1+3x)}{3\sin(3x)} + \lim_{x\to0}\frac{6x}{3(1+3x)\sin(3x)} \\\\ + \lim_{x\to0}\frac{\cos(x)\tan(3x)}{3\sin(3x)} + \lim_{x\to0}\frac{3\sin(x)\sec^2(x)}{3\sin(3x)} \\\\ - \lim_{x\to0}\frac{6x^2}{3\sin(3x)}[/tex]
Now recall two well-known limits:
[tex]\displaystyle \lim_{x\to0}\frac{\sin(ax)}{ax}=1\text{ if }a\neq0 \\\\ \lim_{x\to0}\frac{\ln(1+ax)}{ax}=1\text{ if }a\neq0[/tex]
Compute each remaining limit:
[tex]\displaystyle \lim_{x\to0}\frac{2\ln(1+3x)}{3\sin(3x)} = \frac23 \times \lim_{x\to0}\frac{\ln(1+3x)}{3x} \times \lim_{x\to0}\frac{3x}{\sin(3x)} = \frac23[/tex]
[tex]\displaystyle \lim_{x\to0}\frac{6x}{3(1+3x)\sin(3x)} = \frac23 \times \lim_{x\to0}\frac{3x}{\sin(3x)} \times \lim_{x\to0}\frac{1}{1+3x} = \frac23[/tex]
[tex]\displaystyle \lim_{x\to0}\frac{\cos(x)\tan(3x)}{3\sin(3x)} = \frac13 \times \lim_{x\to0}\frac{\cos(x)}{\cos(3x)} = \frac13[/tex]
[tex]\displaystyle \lim_{x\to0}\frac{3\sin(x)\sec^2(x)}{3\sin(3x)} = \frac13 \times \lim_{x\to0}\frac{\sin(x)}x \times \lim_{x\to0}\frac{3x}{\sin(3x)} \times \lim_{x\to0}\sec^2(x) = \frac13[/tex]
[tex]\displaystyle \lim_{x\to0}\frac{6x^2}{3\sin(3x)} = \frac23 \times \lim_{x\to0}x \times \lim_{x\to0}\frac{3x}{\sin(3x)} \times \lim_{x\to0}x = 0[/tex]
So, the original limit has a value of
2/3 + 2/3 + 1/3 + 1/3 - 0 = 2

the product of a number and cube root of twenty seven
Answer:
If you have a calculator with a "Y^X" function, you can raise 27 to the (1/3) power to get the cube root. Or, take the logarithm of 27, divide it by 3, and then find the anti log. That is, find the base 10 log of 27, divide it by three, and then compute 10 ^ that number. (Or of course you can use the base e log and raise e to the number.)
If you are willing to get into complex numbers, you can find that there are actually three cube roots of 27. One of them is 3. To find the other two, use de Moivre's formula (from Wikipedia):
If z is a complex number, written in polar form as
then the n nth roots of z are given by
where k varies over the integer values from 0 to n − 1.
This formula is also sometimes known as de Moivre's formula.
This leads to the two complex roots,
3 x ( (cos 120 degrees) + i x sin(120 degrees) ) and
3 x ( (cos 240 degrees) + i x sin(240 degrees) ).
These work out to be approximately:
3 x (-0.5 + i x 0.866) and
3 x (-0.5 - i x 0.866).
Step-by-step explanation:
Find set
A={1, 2, 6, 10}
B={3, 6, 9, 10, 11}
C = {1, 2, 4, 7, 11}
If U = {1, 2, 3, …, 12} is the universal set, and
A = {1, 2, 6, 10}
B = {3, 6, 9, 10, 11}
C = {1, 2, 4, 7, 11}
then
(1) A U B is the set containing all elements from A and B,
A U B = {1, 2, 3, 6, 9, 10, 11}
(2) A ∩ B is the set of elements that are contained in both A and B,
A ∩ B = {6, 10}
(3) Unfortunately, A ∩ B U C is somewhat ambiguous. It could mean (A ∩ B) U C or A ∩ (B U C ). Then either
(A ∩ B) U C = {6, 10} U {1, 2, 4, 7, 11} = {1, 2, 4, 6, 7, 10, 11}
or
A ∩ (B U C ) = {1, 2, 6, 10} ∩ {1, 2, 3, 4, 6, 7, 9, 10, 11} = {1, 2, 6, 10}
The first interpretation is probably the intended one, since that essentially reads the set operations from left to right.
(4) A' U B is the union of A' and B, where A' is the complement of A, or all elements in U that are not in A. We have
A' = U - A = {3, 4, 5, 7, 8, 9, 11, 12}
and so
A' U B = {3, 4, 5, 6, 7, 8, 9, 10, 11, 12}
(5) We have
A U C = {1, 2, 4, 6, 7, 10, 11}
so that
(A U C )' = U - (A U C ) = {3, 5, 8, 9, 12}
(6) We have
B' = U - B = {1, 2, 4, 5, 7, 8, 12}
and so
A ∩ B' = {1, 2}
(7) Using the complements found in (4) and (6), we have
A' U B' = {1, 2, 3, 4, 5, 7, 8, 9, 11, 12}
Alternatively, we can use the fact that
A' U B' = (A ∩ B)'
and since we know from (2) that A ∩ B = {6, 10}, we end up with the same result,
(A ∩ B)' = U - (A ∩ B) = {1, 2, 3, 4, 5, 7, 8, 9, 11, 12}
(8) We have
A U B U C = {1, 2, 3, 4, 6, 7, 9, 10, 11}
so that
(A U B U C )' = {5, 8, 12}

Using function concepts, it is found that:
a) The solution for w is [tex]w = \frac{Bh^2}{703}[/tex]b) The weight is of 125 pounds.-------------------------------
The BMI B, for a person of weight w(in pounds) and height h(in inches) is given by:

-------------------------------
Item a:
To solve the formula for w, we isolate w in the equation above, thus:
[tex]B = \frac{703w}{h^2}[/tex]
[tex]703w = Bh^2[/tex]
[tex]w = \frac{Bh^2}{703}[/tex]
-------------------------------
Item b:
64 inches tall means that [tex]h = 64[/tex]BMI of 21.45 means that [tex]B = 21.45[/tex]The weight is:
[tex]w = \frac{21.45(64)^2}{703} = 125[/tex]
The weight is of 125 pounds.

The text of the Pythagorean Theorem The Pythagorean Theorem states: “The sum of the squares of the lengths of the two sides of the right triangle, which are the shortest sides in a right-angled triangle, is equal to the square of the length of the hypotenuse, which is the longest side of the triangle.”
And in symbols: Pythagorean theorem = ( A² + B² = C²)
where ;
● A, B: the two sides of a right triangle ABC.
● C: The hypotenuse of a right triangle is ABC, which is the longest side.
It should be noted that the inverse of the theory is also true; Since the triangle to which the Pythagorean theorem applies, namely: A² + B² = C², is necessarily a right-angled triangle.
