Find the length of the diameter of circle 0
r-ruslan [8.4K]

Answer:

Diameter = 19.33

Step-by-step explanation:

Imaging a radius line from O to the endpoints of the 7. call this line R.

Label the part of the vertical line from O to the 90 degree intersection y.

Now you have a right triangle.

Using the Pythagorean theorem:

R² = 7² + y²

also

y = R - 3

substitute for y:

R² = 49 + (R-3)²

R² = 49 + R² - 6R + 9

simplify:

0 = 58 - 6R

6R = 58

R = 9.6667

Diameter = 2(9.6667) = 19.33

maksim [4K]
<span>First Year - $28,000 with a 7.25% depreciation = 28000 * 7.25% = 2,030 - 28000 = $25,970 Second Year - $25,970 with a 7.25% depreciation = 25970 * 7.25% =1883 - 25970 = $24,087 Third Year - $24,087 with a 7.25% depreciation = 24087 * 7.25% = 1746 - 24087 = $22,341 Fourth Year = $22,341 with a 7.25% depreciation = 1620 - 22341 = $20,721 Fifth Year = $20.721 with a 7.25% depreciation = 1502 - 20721 = $19,219</span>

we know that

<u>Law of detachment </u>is used when you have a conditional statement and another statement that matches the hypothesis of the conditional.

<u>Law of syllogism</u> is used when you have two conditionals and the hypothesis of one matches the conclusion of the other

in this problem we have the law of detachment

<u>the conditional statement is </u>

If a triangle has an angle with a measure more than 90°

<u>the another statement that matches the hypothesis of the conditional</u>

then the triangle is an obtuse triangle

therefore

<u>the answer is</u>
