Answer:

Option A

Step-by-step explanation:

Both brackets must have minus since it has to be shorter and narrower.
So that leaves us with Options A and D
D is expanded wrong since -2x+-10x =-12x and not -8x.
So the answer is Option A

Find the area. Simplify your answer. X+4 2x

sattari [20]

Answer:

x² +4x

Step-by-step explanation:

Area of triangle= ½ ×base ×height

Given: base= 2x, height= x +4

Area of triangle

= ½(2x)(x +4)

= x(x +4)

= x(x) +x(4) (expand)

= x² +4x

A clock is constructed so that it keeps perfect time when its simple pendulum has a period of 1.000 s at locations where g 5 9.8

mafiozo [28]

Answer

Given,

Period of the Pendulum, T= 1 s

acceleration due to gravity, g = 9.8 m/s²

Length of Bob = 0.2482 m

Loss of time in the clock = 1.5 minutes/ day

Loss of time in 1 oscillation

= $\dfrac{1.5\times 60}{24\times 60\times 60}$

= 0.001042

Hence, time period, T = 1 + 0.001042

T = 1.001042 s

a) Using Time period of oscillation formula

$T = 2\pi \sqrt{\dfrac{L}{g}}$

$1.001402 = 2\pi \sqrt{\dfrac{0.2482}{g'}}$

$g' = 9.77\ m/s^2$

Free fall acceleration at the clock location = 9.77 m/s²

b) Length of pendulum bob to keep it perfect time

$1 = 2\pi \sqrt{\dfrac{L}{g}}$

$1 = 2\pi \sqrt{\dfrac{L'}{9.77}}$

$L' = 0.2475\ m$

Hence, Length of pendulum bob is equal to 0.2475 m.
