Use Heron's Area Formula to find the area of the triangle. (Round your answer to two decimal places.) A = 79°, b = 77, c = 43
BlackZzzverrR [31]

Answer:

1549.5

Step-by-step explanation:

Hello There!

Heron's area formula is

A=\frac{(a)(b)sin(c)}{2}

all we have to do is plug in the values

so

A=\frac{77*41sin79}{2} \\77*41=3157\\3157sin79=3098.997018\\\frac{3098.997018}{2} =1549.498509

so the area of the triangle is 1549.498509

our final step is to round to the nearest hundredth

the answer would be 1549.5

A mass weighing 13 lb stretches a spring 4.5 in. The mass is also attached to a damper with coefficient Y. Determine the value o
Gemiola [76]

Answer:55.227

Step-by-step explanation:

Given data

mass \left ( m\right )=13lb

spring stretches by \left ( x\right )=4.5in=0.375 ft

g=32ft/s^2

Now Spring constant K

mg=kx

k=\frac{13\times 32}{y}=58.667lb/ft

For critical damping \zeta =1

2\times \zeta \times \omega_n =\frac{c}{m}

and \omega_n=\sqrt {\frac{k}{m}}

\omega _n=2.1241rad/s

substituting values

2\times 1 \times 2.124 =\frac{c}{m}

c=55.227 lb.sec/ft
