Answer:

Period=3

Step-by-step explanation:

we know that

The<u> period</u> of a periodic function is the interval of x-values on which the cycle of the graph that's repeated in both directions lies.

so

see the attached figure to better understand the problem

To calculate the period subtract 1.5 from 4.5

Period=4.5-1.5=3

The "period" of a repeating function is the change in x between consecutive identical values...in this case 3 units.

Given: BC = 10 inches AC = inches m∠CBD = 60° m∠CAD = 90° Calculate the exact area of the shaded region. Show all work for full
Anna007 [38]

Answer:

23.3285 in²

Step-by-step explanation:

From the above diagram, we can see that the shaded portion is a circular in shape. The shaded portion is coming together of two segments of two circles

The formula for the area of the segment is given as:

A = (½) × r² × [(π/180) θ – sin θ]

 Where,

 r: radius of the circle

θ = angle

a) Circle 1: the largest circle:

A = (½) × r² × [(π/180) θ – sin θ]

 r: radius of the circle = 10 inches

θ = angle = 60°

A = (½) × 10² × [(π/180) × 60° – sin 60]

A = 9.0586 in²

b) Circle 2: the smallest circle:

A = (½) × r² × [(π/180) θ – sin θ]

 r: radius of the circle = √50 inches

θ = angle = 90°

A = (½) × (√50) ² × [(π/180) × 90° – sin 90]

A = 14.2699 in²

 Total area of the shaded portion:

Area of the segment of the large circle + Area of the segment of the small circle

A = 9.0586 in² + 14.2699 in²

A = 23.3285 in²

What evidence do scientists have that erosion works slowly over long periods of time?
zloy xaker [14]
<span>A noticeable evidence is that the Amazon was formed as a result of wearing away that has occurred over millions of years. Another good example is the Grand Canyon in the United States of America, it was formed as a result of erosion that occurred over 3 million years.</span>

Two equations are given below:
Ostrovityanka [42]
A - 3b = 4 . . . . (1)
a = b - 2 . . . . . (2)
Putting (2) into (1), we have
b - 2 - 3b = 4
-2b = 4 + 2 = 6
b = 6/-2 = -3
From (1), a = b - 2 = -3 - 2 = -5
Hence, solution = (-5, -3)

Use separation of variables to solve dy dx − tan x = y2 tan x with y(0) = √3. Find the value of c in radians, not degrees
a_sh-v [17]

Answer:

y(x)=tan(-log(cos(x))+\frac{\pi }{3} )

Step-by-step explanation:

Rewrite the equation as:

\frac{dy(x)}{dx}-tan(x)=y(x)^{2} *tan(x)

Isolating \frac{dy}{dx}

\frac{dy}{dx} =tan(x)+tan(x)*y^{2}

Factor:

\frac{dy}{dx} =tan(x)*(1+y^{2} )

Dividing both sides by (1+y^{2} ) and multiplying them by dx

\frac{dy}{1+y^{2} } =tan(x)dx

Integrate both sides:

\int\ \frac{dy}{1+y^{2} } = \int\ tan(x)  dx

Evaluate the integrals:

arctan(y)=-log(cos(x))+C_1

Solving for y:

y(x)=tan(-log(cos(x))+C_1)

Evaluating the initial condition:

y(0)=\sqrt{3} =tan(-log(cos(0))+C_1)=tan(-log(1)+C_1)=tan(0+C_1)

\sqrt{3} =tan(C_1)\\arctan(\sqrt{3} )=C_1\\60=C_1

Converting 60 degrees to radians:

60degrees*\frac{\pi }{180degrees} =\frac{\pi }{3}

Replacing C_1 in the diferential equation solution:

y(x)=tan(-log(cos(x))+\frac{\pi }{3} )
