2 planes fly in opposite directions. One travels 475 mi/h and the other 525 mi/h . How long will it take before they are 6,000 m

pychu [463]

The speed at which they are moving apart = 475 + 525 = 1000 mi/h

Time = distance / speed
= 6000 / 1000 = 6 hours

The answer is 6 hours.

Answer:

Slope of line is $\pi$

Step-by-step explanation:

Given that the company logo has four concentric circles.

To plot the line on the graph take point as ( Diameter, Circumference )

Circumference of a circle is given by C= $\pi D$

Where D is the diameter.

To draw a line, we need at least two-point.

Now,

Take D=1

Circumference of a circle will be C= $\pi D=\pi$

Required point is (1, $\pi$ )

Take D=0

Circumference of a circle will be C= $\pi D=0 \pi$

Required point is (0,0)

The slope of line is given by s= $\frac{Y2-Y1}{X2-X1}$

Hence,

s= $\frac{Y2-Y1}{X2-X1}$

s= $\frac{0-[tex]\pi$ }{0-1}[/tex]

s= $\frac{[tex]\pi$ }{1}[/tex]

s= $\pi$

Thus, Slope of line is $\pi$

Which statement best describes Marcos equation

satela [25.4K]

Marco's equation is correct. Cosine is an even function, which means that for every x, f(-x) = f(x). In other words, you get the same answer for a negative value that you would for its corresponding positive value.

Translate this phrase into an algebraic expression 23 more than twice a number use the variable n to represent the unknown numbe

Anna71 [15]

In general, 23 more than a number is written as

$x+23$

In our case, x is 'twice a number'; thus,

$x=2*n=2n$

Finally, the whole expression is

$2n+23$ <h2>The answer is 2n+23</h2>

Find all values of x in the interval [0,2π] that satisfy the equation sin2x=cosx. enter your answers as a list of numbers separa

yuradex [85]

$\sin(2x) = \cos(x) \\ 2 \sin(x) \cos(x) = \cos(x) \\ \cos(x) (2 \sin(x) - 1) = 0$
so
$\cos(x) = 0 > > > x = \frac{\pi}{2} + k\pi \\ \sin(x) = \frac{1}{2} > > > x = \frac{\pi}{6} + 2k\pi \\ or \: x = \frac{5\pi}{6} + 2k\pi$
$x = \frac{\pi}{2} or \frac{3\pi}{2} \\ x = \frac{\pi}{6} or \frac{5\pi}{6}$
