A pigeon was sitting 5 meters from the base of a telephone pole and flew 13 meters to reach the top of the pole. How tall is the telephone pole?

12 meters

Step-by-step explanation: We can use the Pythagorean Theorem again, but this time we are solving for B!

A² + B² = C²

5² + B² = 13²

25 + B² = 169

169 - 25 = B²

144  = B²

= B

12 = b

Hope this helps :)

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
