An overhead wire stretches from the service drop that is 20 ft from the ground, on a building to an insulator on a pole 35 ft from the ground. how long is the wire if the pole and building are 48 ft apart?

The cable measures 50.29 ft

Step-by-step explanation:

Graphing the description (see attached) shows the formation of a right triangle, so you can apply the Pythagorean theorem.

Pythagoras' theorem states that in every right triangle, the square of the length of the hypotenuse (in this case, is x) is equal to the sum of the squares of the respective lengths of the legs (in this case, they are y, z).

Be

x = cable length =?

y = distance between pole and building = 48 feet

z = distance from insulator to service drop = (35 - 20) = 15 feet

Then, apply Pythagoras' theorem,

Hence, the cable measures 50.29 ft

Hope this helps!

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
