the distance from a port huron to the indiana state line is approximately 271 miles (via I-94). express this distance in kilomet

riadik2000 [5.3K]

The distance from a port Huron to the Indiana state line = 271 miles (approx)

We have to express the given distance into kilometers.

Since, 1 mile = 1.61 kilometers.

To convert the unit "miles" to "kilometer", we have to multiply the given miles by 1.61 to get the required kilometers.

Therefore, distance in kilometers = $271 \times 1.61$ kilometers

= 436.3 kilometers.

Therefore, the distance from a port Huron to the Indiana state line in kilometers is 436.3 kilometers.

Solve the differential equation. y' + 5xey = 0.

galben [10]

Answer:

The solution is $y = - ln(\frac{5}{2}x^{2} + C)$

Step-by-step explanation:

To solve the differential equation, we will find $y$

From the given equation, y' + 5xey = 0.

That is, $y' + 5xe^{y} = 0$

This can be written as

$\frac{dy}{dx} + 5xe^{y} = 0$

Then,

$\frac{dy}{dx} = - 5xe^{y}$

$\frac{dy}{e^{y}} = - 5x dx$

Then, we integrate both sides

$\int {\frac{dy}{e^{y}}} =\int {- 5x dx}$

$\int {e^{-y}dy }} =\int {- 5x dx}$

Then,

$-e^{-y} = -\frac{5}{2}x^{2} + C$

$e^{-y} = \frac{5}{2}x^{2} + C$

Then,

$ln(e^{-y}) = ln(\frac{5}{2}x^{2} + C)$

Then,

$-y = ln(\frac{5}{2}x^{2} + C)$

Hence,

$y = - ln(\frac{5}{2}x^{2} + C)$

If sin(x) = cos(y) for acute angles x and y, how are the angles related?

Vesnalui [34]

Answer:

b. complementary

Step-by-step explanation:

-Complementary angles are angles that add up to 90°.

-These are usually the two acute angles in the right triangle.

#To verify, lets take the two angles 30° and 60°:

$Cos \ 60\textdegree=0.5\\\\Sin \ 30\textdegree=0.5\\\\\therefore Sin \ 30\textdegree=Cos \ 60 \textdegree=0.5$

#We can reverse as:

$Sin \ 60\textdegree=0.86603\\\\Cos \ 30\textdegree=0.86603\\\\\therefore Sin \ 60\textdegree=Cos \ 30\textdegree=0.86603$

Hence, two angles are said to be complimentary if they sum up to 90°.

Jessica bought a soft drink for 2 dollars and 6 candy bars. She spent a total of 20 dollars. How much did each candy bar cost!

liq [111]

Answer:

4 dollars

Step-by-step explanation:

i subtracted the total money spend from the soft drink

18$ - 2$ = 16$ was spent in buying the candy bars

and she bought 4 candy bars so we divide 16$ by 4 = 4$ for each candy bars
