Mathematics

siniylev [52]3 years ago

Answer:

x = 64

Step-by-step explanation:

Given HI and JK are parallel lines, then

∠HIA = ∠JKI = 60° ( corresponding angles )

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles in ΔHIA from 180

x = 180 - (56 + 60) = 180 - 116 = 64

Answer:

64

Step-by-step explanation:

60 + 56 + x = 180

116 + x = 180

x = 180 - 116

x = 64

Answer:

Line = 180 degrees

137 is angle

x = unknown

180-137 = x

The equation of motion for a weight suspended from a particular spring is given by p(t)=2sint3+5cost3p(t)=2sin⁡t3+5cos⁡t3, where
daser333 [38]
The given displacement at time, t, is
p(t) = 2 sin(t³) + 5 cos(t³)

The initial equilibrium position is
p(0) = 5

To determine future equilibrium postions, define
f(t) = p(t) - 5 = 2 sin(t³) + 5 cos(t³ - 5
The derivative of f(t) is
f'(t) = (3t²)[2 cos(t³) - 5sin(t³)]

Equilibrium is established when f(t) = 0.
To solve this equation numerically, we shall use the Newton-Raphson method, given by.
t(n+1) = t(n) - f[t(n)]/f'[(t(n)], n=0,1,2, ...,

As a guess, let (0) = 1.
The iterative solution for t is shown below.

  n         t(n)
 ---   -----------
   0   1.0000
   1    0.9344
   2   0.9147
   3   0.9130
   4   0.9130

The solution converges rapidly to t = 0.913 s.
The graphical solution (shown below) confirms the numerical solution.

Answer:
The weight first reaches the equilibrium position in 0.913 sec.

If f(x)=4x^3 - 6x^2 + 2x - 5, then f(-2) = ___________
Art [367]

f(x)=4x^3 - 6x^2 + 2x - 5

f(-2)


Replace X with -2:

4(-2)^3 - 6(-2)^2 + 2(-2) - 5 =

Calulate the powers:

4(-8) - 6(4) +(-4) -5=

Multiply:

-32 - 24 -4 -5=

Subtract
