Answer:
B. cosθ ≠ 0
Step-by-step explanation:
As we notice, tanθ is a fraction. Fractions are undefined when the denominator is equal to or approaching 0 because one cannot divide by zero. Thus, the denominator in this case is cosθ, and therefore it cannot equal zero for the equation to be true.
Answer:
<h2>x = 1</h2>
Step-by-step explanation:

Expand the terms in the bracket and simplify
That's

<u>Add 2x to both sides of the equation</u>

<u>Subtract 3 from both sides of the equation</u>

<u>Divide both sides by 5</u>

We have the final answer as
<h3>x = 1</h3>
Hope this helps you
For this case by similarity of triangles we can use the following relationship:
(x) / (9) = (5) / (15)
We clear the value of x:
x = ((5) / (15)) * (9)
Rewriting:
x = (1/3) * (9)
x = 3
Answer:
The value of x for this case is:
x = 3
Answer:
![24\sqrt[3]{x^{7}}](https://tex.z-dn.net/?f=24%5Csqrt%5B3%5D%7Bx%5E%7B7%7D%7D)
Step-by-step explanation:
The exponent rule that applies to products like this is ...
... (a^b)(a^c) = a^(b+c)
In your problem, this is
... x^(1/3)·x^2 = x^(1/3 +2) = x^(1/3 +6/3) = x^(7/3)
This fractional exponent translates to the root of a power:
... = (x^7)^(1/3)
In typeset form, it is ...
![\sqrt[3]{x^{7}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B7%7D%7D)
You have already figured correctly that the coefficient is 3·8 = 24.
