PLLLEEEAASSEE HELP ME<br><br> explain how you got the answer
valkas [14]
For # 1, the answer will be 1 because of the exponential rule a^{0} = 1.

#2, the answer is going to be x^{4} because of the exponential rule a^{-b} = \frac{1}{a ^{b} }.

#3. I'm not sure that this could be simplified any further.

#4  To get the answer to this question, we must apply the distributive property, along with the exponential rule a ^{m} × a ^{n} = a ^{m+n}. When we apply these properties, we'll get - \frac{3}{x^4}

For the other questions, they all apply the Laws of Exponents.

A boat heads north across a river at a rate of 2 miles per hour. If the current is flow A boat heads north across a river at a r
Ivahew [28]

Answer:

\textrm{Resultant velocity}\ =\ \sqrt{29}\ miles/hour

along the direction 68.19° from north.

Step-by-step explanation:

Given,

  • speed of the boat, u= 2 miles/hour along north
  • speed of the river, v= 5 miles/ hour along east

Since, north and east are perpendicular to each other, so we can write the resultant velocity in vector form as,

\vec{r}\ =\ 2\hat{i}+5\hat{j}

Hence, the magnitude of resultant velocity can be written as

r\ =\ \sqrt{2^2+5^2}

  =\ \sqrt{4+25}

  =\ \sqrt{29}

Hence, the magnitude of resultant vector is \sqrt{29} moles/hour.

And the direction of the boat can be given by,

tan\theta\ =\ \dfrac{5}{2}

=>\ tan\theta\ =\ 2.5

=>\ \theta\ =\ tan^{-1}2.5

                 = 68.19°

Hence, the resultant velocity of boat is \sqrt{29} miles/hour along the direction making an angle 68.19° with the north.
