Write the equation of a line perpendicular to the line: y=−5/2x+4 that goes through the point (-6, 0).
NikAS [45]

Step-by-step explanation:

the line given slope = x coefficient = -5/2

Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

new slope = 2/5

line equation formula = y = mx+ b

m = slope

y= 2/5x + b

from the point given (-6,0)

x = -6

y = 0

0= -12/5 + b

b = +12/5

line equation =

y =  \frac{2}{5} x +  \frac{12}{5}

The time period, T, of a simple pendulum is directly proportional to the square root of the length, d, of the pendulum.
amid [387]

Step-by-step explanation:

T = k * sqrt(d), where k is a real constant.

When d = 6, T = 5.

k = T / sqrt(d) = 5 / sqrt6.

Therefore when d = 3, T = (5 / sqrt6) * sqrt3 = 3.53.
