Ajewelry company prints a hidden watermark on the logo of all its official documents. the watermark is a chord located 0.7cm. from the center of a circular ring that has 2.5cm. radius. what’s the length of the chord to the nearest tenth

4.8 cm

Step-by-step explanation:

You will need to use the Pythagorean Theorem. And from there, you would solve using the exponents

0.7^2 + b^2 = 2.5^2

0.49 + b^2 = 2.5^2

0.49 + b^2 = 6.25

You would subtract 0.49 on both sides to get the b^2 by itself.

6.25 - 0.49 = 5.76

b^2 = 5.76

Now, you would use the square root in order to get "b" without the exponents, since the final answer has to have a variable that is by itself as "1"

√b^2 = √5.76

b = 2.4

Now, multiply 2.4 by 2.

4.8 cm

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
