A spring is hanging from a ceiling. The length L(t) (in cm) of the spring as a function of time t (in seconds) can be modeled by

Zanzabum

Answer:

L(t) = 5·sin(πt) +7

Step-by-step explanation:

The middle of the oscillation of the given function occurs when t=0. At that point, ...

L(0) = d = 7

The next maximum of the oscillation occurs when the argument of the sine function is π/2.

b·t = π/2

b = π/(2t) = π/(2·0.5) = π

At that maximum, the length is 12, so we have ...

L(0.5) = a·sin(0.5π) +7 = 12

a = 5

The function L(t) is ...

L(t) = 5·sin(πt) +7

Answer:

$x=8$

Step-by-step explanation:

<h3>Given:-</h3>

$RS=28$

$RT=3x+4$

Solve for x.

<h3>According to question:-</h3>

[Tangent of same circle are equal]

$=>3x+4=28$

$=>3x=28-4$

$=>3x=24$

$=>x=\frac{24}{3}$

<h3>The value of x is 8.</h3>

Answer:

$-\frac{9}{11}$

Step-by-step explanation:

$-\frac{6}{11} + -\frac{3}{11} = -\frac{6}{11} - \frac{3}{11} = -\frac{6+3}{11} = -\frac{9}{11}$
