Answer:

3.45× $10^{5}$

Step-by-step explanation:

The proper way to put a number in scientific notation is a specific way. So the answer you see above is the proper way you would put a number in scientific notation.

So. Put the decimal in between 3 and 4.

3.45000

Now count from the last 0 to 4. Which is 5. (Scientific notation can only be with 0's not any other number.)

So, it would be:

3.45× $10^{5}$

Hope this helped!

Two ships leave the same port in different directions, forming a 120° angle between them. One ship travels 70 mi. and the other

kondaur [170]

Answer : Distance between the ships to the nearest miles = 106.03 ≈ 106 mi.

Explanation :

Since we have shown in the figure below :

a=70 mi.

b=52 mi.

c=x mi.

$\text{Since two ships leaves the same port in different directions forming a }120\textdegree\text{angle between them.}$

So, we use the cosine rule , which states that

$c^2=a^2+b^2-2ab.cosC\\\\x^2=70^2+52^2-2\times 70\times 52\times cos(120\textdegree)\\\\x^2=4900+2704-7280\times (-0.5)\\\\x^2=7604+3640\\\\x^2=11244\\\\x=\sqrt{11244}\\\\x=106.03$

So, c = x= 106.03 mi.

Hence, distance between the ships to the nearest miles = 106.03 ≈ 106 mi.

What angle has a tangent and sine that are both negative? 300 210 45 150

zimovet [89]

Answer:

$300^{\circ}$

Step-by-step explanation:

$\text{In quadrant IV, both ratios of tangent and sine are negative.}\\ \\300^{\circ}~ \text{lies in the fourth quadrant, so}~ \tan 300^{\circ} ~ \text{and}~ \sin 300^{\circ}~ \text{are negative.}$
