Answer:
Just like combining like terms with the same variables, you combine like
radicals with the same number under the radical signs.
Step-by-step explanation:
Example:
3x + 2x
= 5x {combined like terms}
3√2 + 2√2
= 5√2 {combined like radicals}
Answer:
Step-by-step explanation:
x = cos θ + sin(10θ)
y = sin θ + cos(10θ)
Take derivative with respect to θ:
dx/dθ = -sin θ + 10 cos(10θ)
dy/dθ = cos θ - 10 sin(10θ)
Divide:
dy/dx = (dy/dθ) / (dx/dθ)
dy/dx = (cos θ - 10 sin(10θ)) / (-sin θ + 10 cos(10θ))
Evaluate the derivative at θ=0:
dy/dx = (cos 0 - 10 sin 0) / (-sin 0 + 10 cos 0)
dy/dx = 1/10
Evaluate the parametric functions at θ=0:
x = cos 0 + sin 0 = 1
y = sin 0 + cos 0 = 1
Writing the equation of the tangent line in point-slope form:
y - 1 = 1/10 (x - 1)
Step-by-step explanation:
PRIMERO CONVIERTES MINUTOS A HORAS
15 MIN = 0.25 h
LUEGO CON LA ECUACIÓN DE GALILEI:
<em>x</em> = 6.5 mi/0.25 h = 26 mi
Divide the population of 65 or older by the percentage:
30.2 million / 0.122 = 247.54 million total population. (Round answer as needed)
