Awire that is 22 feet long connects the top of a pole to the ground. the wire is attached to the ground at a point that is 10 feet from the base of the pole.

what is the height of the pole? round to the nearest hundredth.
12.00 feet
19.60 feet
24.17 feet
38.40 feet

Solution:

Length of wire = 22 feet =AB

Distance between the point where wire is attached to the ground from the point on the ground where pole is fixed= 10 feet=OB

In Right Δ O A B

By Using pythagoras theorem

O A²  + OB² = AB²

O A² +10²= 22²

O A²= 484 - 100

O A²= 384

O A= √384= 19.60 (Approximately)

So, the height of pole to nearest hundredth = 19.60 feet  

savings account is an account only used for saving money. this acts as an emergency source of funding for an individual. answer a would result in the money in his account to grow as it specifically states that interest is compounded daily at the rate of 2%

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
