Answer:

x=0.111111111 (I don't know how many decimal points you need to round to)

Step-by-step explanation:

We are given the equation

log_{20} 2187+log_{20} x=5log_{20} 3

Now we can begin to solve for x

log_{20} x=5log_{20} 3-log_{20} 2187\\\\x=20^{5log_{20} 3-log_{20} 2187} \\\\x=0.111111

Find the domain of the function shown. Write the answer in interval notation.
lara31 [8.8K]

( - ∞, 3) ∪ (3, ∞ )

The domain is the set of values of x which make f(x) defined

The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be.

solve x - 3 = 0 ⇒ x = 3

domain : (- ∞, 3) ∪ (3, ∞ )

Some questions have the form y = kx, where k is a number. Drag each question to the correct category below. ( X = y/2 ),( y = .1
fomenos

Answer:

<u>Has the form y = kx</u>

( y = 0.11x)

(y = 0.04x)

<u>Can be put into form y = kx</u>

(z/x = 9)

<u>Other</u>

(5 = xy)

( x = y/2)

Step-by-step explanation:

<u>y = kx</u>

( y = 0.11x)

(y = 0.04x)

<u>kx = y</u>

(z/x = 9)

-----------

( x = y/2 )

( x - 5 = y)

(5 = xy)

In triangle ABC, a = 4, b = 6, and cos C = − 1/4. What is the length of side c?
shusha [124]

The length of side c would be 8.

Step-by-step explanation:

Given that,

a = 4

b = 6

cosC = -1/4

If we are given two sides and angle, the law of Cosines can be used to find the third side:

c^{2} = a^{2} + b^{2} - 2ab (cos(c))

By inserting the values in the formula, we get

c^{2} = 4^{2} + 6^{2} - 2.4.6 (-\frac{1}{4} )

c^{2} = 16 + 36 + 12

c^{2} = 64

\sqrt{c^{2} } = \sqrt{64}

c = 8.

Therefore, the length of side c would be 8.
