The equation of motion is
  s(t) = (1/2)a·t² +v₀·t +s₀
where a is the acceleration, v₀ is the initial velocity, and s₀ is the initial position.

For t in seconds and s(t) in feet, your values make this equation be
  s(t) = 5t² -20t +8

(cos A + cos b)^2 + (sin A + sin B)^2=?
emmasim [6.3K]
First, we expand the equation:

cos^{2}A+2cosAcosB+ cos^{2}B+sin^{2}A+2sinAsinB+sin^{2}B

Then, we combine certain terms in order to simplify them using trigonometry identities.

cos^{2}A+sin^{2}A+cos^{2}B+sin^{2}B+2cosAcosB+2sinAsinB

Note these identities:
Pythagoran relation: cos^{2}A+sin^{2}A = cos^{2}B+sin^{2}B=1
Sum and Difference Formula/Identities: cos(A-B) = cosAcosB+sinAsinB

Thus, if we apply these identities, the simplified equation would be:
2(cos(A-B))+2

Simplying further, the answer would be

2[cos(A-B)+1]

Find the value of x?!??????
PilotLPTM [1.2K]

Answer:

x = 31

Step-by-step explanation:

Given:

MN = 20

PQ = x

RS = 42

Required:

Value of x

SOLUTION:

In a trapezoid, the midsegment length equals the sum of both bases divided by 2

This implies that:

PQ = ½(MN + RS)

Plug in the values

x = ½(20 + 42)

x = ½(62)

x = 31
