A) The shortest possible distance will be traveled if he moves straight from one side of the bank to the next, without any diagonal movement. Thus, he should steer southeast in order to counter the flow of the river from the east and also move towards his destination in a straight line.

b) The x-component of this wind can be calculated using:
Wx = 6cos(45)
Wx = 4.24 km/hr
This is greater than the opposing flow of the river from the east. Therefore, should row in a direction due south west to counter the wind's force as well as move towards his destination.

A tree's height increase by 15%. If a tree is 23 feet high, how tall will it be in one year ?
Ghella [55]

Increased height:-

\\ \sf\longmapsto 23\times 15\%

\\ \sf\longmapsto 23\times \dfrac{15}{100}

\\ \sf\longmapsto \dfrac{345}{100}

\\ \sf\longmapsto 3.45

Now current height:-

\\ \sf\longmapsto 23+3.45=26.45ft

3q+4+9=-14 <br> what is Q
BlackZzzverrR [31]

Hi! Your answer is q = -9

Please see an explanation for a better and clear understanding to your problem.

Any questions about my answer and explanation can be asked through comments! :)

Step-by-step explanation:

Since we want to solve for q-term. That means we are going to isolate q-term.

\huge{3q+4+9=-14}

We can add 4 and 9 together.

\huge{3q+13=-14}

Because we want to know the value of q. That means we have to isolate q-term by subtracting both sides by 13.

\huge{3q+13-13=-14-13}\\\huge{3q=-27}

We are reaching to the final step where we divide the whole equation by 3.

\huge{\frac{3q}{3}=-\frac{27}{3}}\\\huge{q=-9}

Finally, the solution for this equation is q = -9. But what if you are not certain or sure about the answer? Let's check it out!

To check the answer, simply substitute q = -9 in the equation.

\huge{3q+4+9=-14}\\\huge{3(-9)+13=-14}\\\huge{-27+13=-14}\\\huge{-14=-14}

Notice that the equation is true for q = -9. Hence, we can conclude that the solution for this equation is q = -9.

Hope this helps!
