Answer:
29.5788
Step-by-step explanation:
Multiply all of the terms together
Answer:
yes you just have to solve for both x and y in the top system and then solve the other systems to find out which one has the same solutions
Step-by-step explanation:
hope this helps!
1.
An expression of the form

is called a "compound fraction"
Compound fractions can be written as simple fractions by multiplying c to a, and then adding the product to c as follows:

for example,

can be written as:

2.
when we subtract or add a fraction

from an integer k,
we first write k as a fraction with denominator n. We can do this as follows:

for example, if we want to subtract

from 8,
we first write 8 as a fraction with denominator 2:

3.
Thus,

4.
The simple fraction 7/2 is not an option, so we write it as a compound fraction as follows:

(So write 7 as the sum of the largest multiple of 2, smaller than 7 + what is left. In our case these numbers are 6 and 1, then proceed as shown)
5. Answer: D
<u>Part a) </u>
we know that
An isosceles triangle has two base angles that are congruent
The sum of two base angles plus the vertex angle is equal to
degrees
so
In this problem



Solve for x




therefore
<u>the answer part a) is</u>
the value of x is 
<u>Part b)</u> What is the measure of each base angle?
we know that

we have that

substitute the value of x in the equation


therefore
<u>the answer part b) is </u>
the measure of each base angle is 
Answer:
Circle: sin²(theta) + cos²(theta) = 1
Ellipse: sin²(theta) + cos²(theta) = 1
Hyperbola: sinh²(theta) - cosh²(theta) = 1
Step-by-step explanation:
Circle
Cartesian form from polar form:
x = rcos(theta)
y = rsin(theta)
x² + y² = r²sin²(theta) + r²cos²(theta)
x² + y² = r²(sin²(theta) + cos²(theta))
Using sin² + cos² = 1, we get
x² + y² = r²
Ellipse
x = acos(theta)
y = bsin(theta)
cos(theta) = x/a
sin(theta) = y/b
x²/a² + y²/b² = sin²(theta) + cos²(theta)
x²/a² + y²/b² = 1
Hyperbola
x = rcosh(theta)
y = rsinh(theta)
x²/r² - y²/r² = sinh²(theta) - cosh²(theta)
x²/r² - y²/r² = 1
