Answer: hello your question is poorly written below is the complete question

Find the angle between and if ⋅=3√2‖‖⋅‖‖.

(Use symbolic notation and fractions where needed. Give your answer in terms of . )

answer :

∅ = π / 6

Step-by-step explanation:

V .W = $\frac{\sqrt{3} }{2} || V ||. ||W||$

Hence

∅ = cos^-1 ( $\frac{\frac{\sqrt{3} }{2} || V ||. ||W||}{||V||.||W||}$

∅ = cos^-1 ( $\frac{\sqrt{3} }{2}$ )

∴ ∅ = π / 6

- 2(x + 3) + 2(x + 4) = 24

ANTONII [103]

Answer: no solution

Step-by-step explanation:

First lets simplify

-2(x+3) + 2(x+4) = 24

-2x - 6 + 2x + 8 = 24

We can simplify this further by combining like terms

2=24 is the equation we get after combining like terms.

Since 2 is not equal to 24, the answer is no solution.

Is this right? Or is the answer B?

baherus [9]

For this case we must find an expression equivalent to:

$\sqrt [4] {f}$

By definition of properties of powers and roots we have:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

So, rewriting the given expression we have:

$f ^ {\frac {1} {4}}$

Answer:

Option 1
