What are the three elements to calculate simple interest
Arisa [49]
Simple interest is found by multiplying the amount of money deposited, the rate ( like .05 per month ) , and the time it will be in the bank ( one moth, 5 months, a year, etc. ).

I'm 1000% positive this is correct.

Hope I helped you learn something new today!

What is the approximate length of a pendulum that takes 2.4 pi seconds to swing back and forth?
sertanlavr [38]

Answer:

The approximate length of the pendulum is 46.08 ft

Step-by-step explanation:

The time (t) of pendulum oscillation is given as;

t = 2 \pi\sqrt{\frac{L}{g} }

where;

L is the length of the pendulum

g is acceleration due to gravity = 9.8 m/s² = 32.15 ft/s²

t is the time given as 2.4 π seconds

From the equation above, make L the subject of the formula;

t = 2 \pi\sqrt{\frac{L}{g} } \\\\\frac{t}{2\pi} = \sqrt{\frac{L}{g} }\\\\(\frac{t}{2\pi} )^2 =\frac{L}{g}  \\\\L = g*(\frac{t}{2\pi} )^2\\\\L = 32.15*(\frac{2.4 \pi}{2\pi} )^2\\\\L = 32.15 *1.44\\\\L = 46.296 \ ft

Therefore, the approximate length of the pendulum is 46.29 ft

The closest option is 46.08 ft

What is the slope of the line that passes through the pair of points (-10,14) and (-6,12).
Inga [223]

Answer:

Step-by-step explanation:

(-10,14) and (-6,12)

y2 = 12, y1 = 14, x2 = -6, x1 = -10

Slope m = (y2 - y1)/(x2 - x1)

m = (12 - 14)/(-6 + 10)

m = -2/4

m = -1/2

The equation of line

y - y1 = m(x - x1)

y - 14 = -1/2(x + 10)

y - 14 = -x/2 - 5

y = -x/2 - 5 + 14

y = -x/2 + 9
