Given:
.
To find:
The value of r.
Solution:
We have,
.
We know that the radius is perpendicular to the tangent at the point of tangency
AD is the tangent and CD is the radius. So, CD is perpendicular to AD at point D, i.e.,
.
Using Pythagoras theorem, we get




On further simplification, we get



Therefore, the value of r is 9.
Step-by-step explanation:
e^ln x - ln xy is equal to (a) y (b) 1/y (c) x (d) 1/x (e) none of these Which of the following equations is equivalent to the equation y = 5^x? (a) y = ln(5x) (b) y = e^5 ln x (c) y = e^x ln 5 (d) y = x ln 5 (e) none of these When $400 is invested in an account that earns 7.5% annualinterest, compounded quarterly, the accumulated value after 5 years (to the nearest cent) is (a) $581.99 (b) $579.98 (c) $574.25 (d) $550.00 (e) none of these
Answer:
76 cm
Step-by-step explanation:
To find perimeter, you find the total of the sides.
A rectangle has 4 sides, and 2 equal sides.
So, add 14+14 which is 28.
Then add 24+24 which is 48.
Now add 48 and 28.
48+28=76
<u>Final answer</u>
76 cm
Answer:
Using a calculator, if you typed in 9 divided by 2, you'd get 4.5. You could also express 9/2 as a mixed fraction: 4 1/2.
I don’t understand Exactly Either but you could ask the internet text someone in your family to
