1,088 if you set it up as a proportion. It would be 17/20 compared to x/1280 multiply 17 by 1280 and then divide by 20.

Find the value of x and the value of y.
jeka57 [31]

Answer:

x =  6/√3  ,   y = 12/√3

Step-by-step explanation:

sin 60° = opposite /hypothenus

√3/2 = 6/y

cross multiply

√3y=6 x 2 = 12

y = 12/√3

Tan 60° = opposite/adjacent

tan 60° = √3

√3 = 6/x

√3x= 6

x = 6/√3

which expression is not equal to the expression shown? 3 to the 3rd power divided by 3 to the negative 4th power. Need the answe
Alecsey [184]

Answer:

3^{-3} ÷ 3^{4}

Step-by-step explanation:

Evaluate 3^3 ÷ 3^{-4}, then evaluate each given expression to find which of them will give us the same result.

3^3 ÷ 3^{-4}

27 ÷ \frac{1}{3^4} (recall: a^{-x} = \frac{1}{a^x}

27 ÷ \frac{1}{81}

27 * \frac{81}{1} (changing from division operation to multiplication by flipping the fraction to our right upside down)

27 * 81 = 2,187

Let's compare the expressions in the given options to the value we got above:

Option 1: 3*3⁶

= 3*729 = 2,187 (this is equal)

Option 2: 3⁷ ÷ 3⁰

= 2,187 ÷ 1 (recall: x⁰ = 1, therefore, 3⁰ = 1)

= 2,187 (this is equal)

Option 3: 3³ * 3⁴

= 27*81 = 2,187 (this is equal)

Option 4: 3^{-3} ÷ 3^{4}

\frac{1}{3^3} ÷ 81

\frac{1}{27} ÷ 81

\frac{1}{27} * \frac{1}{81} (changing from division to multiplication)

= \frac{1*1}{27*81}

= \frac{1}{2,187} (not equal)

3^{-3} ÷ 3^{4} i not equal to 3^3 ÷ 3^{-4}.
