the russian ice breaker Yamal can move forward through 2.3 meter 2.3 meter thick ice at a speed 5.5 kilometers

morpeh [17]

Answer:

Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.

Step-by-step explanation:

Given:

Speed = 5.5 km/hr

Distance = 82 km

Let time be represented as 'x'.

We need to find the number of hours required to travel 82 km.

We know that Distance can be calculated by the product of Speed and time.

Framing above sentence in equation form we get;

Distance = Speed × Time

Substituting the given value we get;

$82 = 5.5x$

Hence The expression for number of hours is $82 = 5.5x$

Solving the equation to find the value of x we get;

$82 = 5.5x\\\\x=\frac{82}{5.5} = 14.90 \approx 15\ hrs$

Hence Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.

Solve the given equation over the interval [0, 2π): csc^2 x + 2 csc x = 0.

Anastaziya [24]

$csc^2x+2cscx=0$
Factor out the GCF which is csc x
$cscx(cscx+2)=0$
Set each factor equal to zero.
$cscx=0$ or $cscx+2=0$
Using the reciprocal sine function we can replace csc in the equations.
$\frac{1}{sinx} =0$ or $\frac{1}{sinx} +2=0$
The first equation yields 1 = 0 which is not true. However the second equation does offer 2 possible answers.
When solved for sinx you get $sinx=- \frac{1}{2}$
The sine function is negative in the 3rd and 4th quadrants.
You can use the unit circle or the $sin^-^1$ feature on your calculator $sin^-^1(1/2)$
$210^o or 330^o$ alter radian answer which is probably what you want is $\frac{7 \pi }{6} or \frac{11 \pi }{6}$
