rationalize the denominator and simplify √a + 2√y/√a-2√y
Answer:
[tex]\sqrt{a} + \frac{2\sqrt{ya} }{a} - 2\sqrt{y}[/tex]
Step-by-step explanation:
Simplify each term.
The rationalized and simplified form of the expression (√a + 2√y) / (√a - 2√y) is (a + 4√ay + 4y) / (a - 4y).
To rationalize the denominator and simplify the expression (√a + 2√y) / (√a - 2√y), we can use a technique called rationalizing the denominator.
First, we multiply both the numerator and denominator by the conjugate of the denominator, which is (√a + 2√y). This is done to eliminate the square root in the denominator.
(√a + 2√y) / (√a - 2√y) * (√a + 2√y) / (√a + 2√y)
Expanding the numerator and denominator:
(√a * √a) + (√a * 2√y) + (2√y * √a) + (2√y * 2√y) / ((√a * √a) - (√a * 2√y) + (2√y * √a) - (2√y * 2√y))
Simplifying:
a + 2√ay + 2√ay + 4y / (a - 2√ay + 2√ay - 4y)
Combining like terms:
a + 4√ay + 4y / (a - 4y)
Therefore, the rationalized and simplified form of the expression (√a + 2√y) / (√a - 2√y) is (a + 4√ay + 4y) / (a - 4y).

What is the quotient of 1.485 x 10^6 and 4.95 x 10^2 expressed in science notation
____ x 10^—
ANSWER ASAP
Answer:
3 x 10^3
Step-by-step explanation:
1.485 / 4.95 = 0.3
10^6 : 10^2 = 10^(6-2) = 10^4
0.3 x 10^4
3 x 10^3
The quotient of 1.485 x 10^6 and 4.95 x 10^2 expressed in science notation is 3 x 10^3
How does scientific notations work?The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10.
Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.
WE need to find the quotient of 1.485 x 10^6 and 4.95 x 10^2 expressed in science notation.
So we have;
1.485 / 4.95 = 0.3
Therefore,
10^6 : 10^2
= 10^(6-2)
= 10^4
Hence, the scientific notation written as;
0.3 x 10^4
= 3 x 10^3

Compound probability using a organized list
Answer:
[tex]\huge\boxed{\sf Probability = \frac{3}{8} }[/tex]
Step-by-step explanation:
[tex]\displaystyle Probability = \frac{Number \ of \ codes \ with \ 2 \ 0s}{Total \ number \ of \ codes}[/tex]
According to the fundamental principle of counting, to find the total number of codes, we need to multiply the number of options we have for each digits by the number of digits. Hence, we have two options for each digit ( 1 and 0 ) and we have 4 digits. So,
= 2 * 2 * 2 * 2
= 16 possible codes (Total)
Now, Codes with two zeroes:
= 0101,0011,1100,1010,1001,0110 (Maximum number of codes for 2 0s)
Hence, The probability:
Probability = 6 / 16
Probability = 3 / 8

~AH1807The set of all values that a function will return as outputs is called the _________ of the function.
Answer:
Range.
Step-by-step explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
Furthermore, the set of all values that a function will return as outputs is called the range of the function.
This ultimately implies that, the range of a function is simply a complete set of possible values that are generated from a dependent variable after a domain has been substituted. Thus, a range is the resulting values from a data set when all the possible input values have been substituted.
If sin 0= 4/5 in quadrant II, what is cose? A. - 3/5 B. 3/5 C. - 3/4 D. 3/4
Answer:
A
Step-by-step explanation:
Given
sinθ = [tex]\frac{4}{5}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]
This is a 3- 4- 5 triangle
with opposite = 4, adjacent = 3 and hypotenuse = 5
Since θ is in second quadrant then cosθ < 0
cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = - [tex]\frac{3}{5}[/tex] → A

An isosceles triangle has base angles that each measure 42°. Which equation can be used to find z, the measure of the third angle of this isosceles triangle in degrees? \
Answer:
42 + 42 + z = 180
Step-by-step explanation:
Note that:
Base angles in an isosceles triangle are equal in measure.
The sum of angles in a triangle is 180°.
Thus, the equation would be
42 + 42 + z = 180

for positive acute angles A and B, it is known that cos A=20/29 and sin B=60/61. Find the value of sin(A+B) in simplest form.
Answer:
[tex]sin(A+B) = \frac{1431}{1769}[/tex]
Step-by-step explanation:
sin(A+B) = sinA cosB + cosA sinB ------(1)
[tex]given : cos A = \frac{20}{29}, \ sinB = \frac{60}{61}[/tex]
First we will find sinA and cosB
[tex]We \ know \ sin^2 A + cos^2A = 1\\\\sin^2 A = 1 - cos^2A = 1 - (\frac{20}{29})^{2} = \frac{841-440}{841} = \frac{441}{841}\\\\sinA =\frac{21}{29}[/tex]
[tex]sin^2B +cos^2B = 1\\\\cos^2B = 1 - sin^2B = 1 - (\frac{60}{61})^2 = \frac{3721-3600}{3721} = \frac{121}{3721}\\\\cosB = \frac{11}{61}[/tex]
Substitute all values in (1)
[tex]sin(A+B) =sinAcosB + cosAsinB[/tex]
[tex]=(\frac{21}{29} \times \frac{11}{61} )+ (\frac{20}{29}\times \frac{60}{61})\\\\=\frac{231}{1769} + \frac{1200}{1769}\\\\= \frac{1431}{1769}[/tex]
