Answer:

It is only 1 and 2 that is the solution to the differential equation

Step-by-step explanation:

1. x''=- 2 Cos t+ 3 sin t and x=2 cos t -3 sin t the addition give 0

2. d^2y/dx^2=- Sin x +2 and y =Sin x +x^2 the addition =x^2+2

but

3. dx/dt= -2 Sin 2t and tx =t Cos 2t =t( 2Cos t - 2 Sin t) the addition it can't equal Sin 2t

While watching a circus show, I counted out the number of acrobats and elephants. I counted 40 legs and 15 heads. How many acrob

Goryan [66]

Answer:

y=10 ( number of acrobat)

Step-by-step explanation:

let x be the elephant and y the acrobat

elephant has 4 legs and acrobat 2

4x+2y=40

x+y=15 ⇒x=15-y

substitute for x in the equation:

4(15-y)+2y=40

60-4y+2y=40

-2y=40-60

y=-20/-2

y=10 ( number of acrobat)

number of elephant=15-10=5 elephants

Match each trigonometric function with its Unit Circle definition. Note that Angle A is correctly oriented for the Unit Circle d

PtichkaEL [24]

The first diagram below shows a circle with a radius of 1 (unit circle). The circle is drawn on a Cartesian graph with (0,0) as the center of the circle.

From the second diagram, we can determine the value of sin(Θ) = y
and cos(Θ) = x

We can further deduce that
tan(Θ) = $\frac{y}{x}$
sec(Θ) = $\frac{1}{cos(Θ)}$ = $\frac{1}{x}$
cosec(Θ) = $\frac{1}{sin(Θ)}$ = $\frac{1}{y}$
cot(Θ) = $\frac{cos(Θ)}{sin(Θ)}$ = $\frac{x}{y}$
