Answer:
1,000 + 200 + 70
Step-by-step explanation:
Expanded form is a way of writing numbers to see the math value of individual digits.
so for example:
5,000 + 300 + 20 + 3
is 5,323.
Given:
m∠NRQ = 60°
To find:
The angle measure of minor arc NQ
Solution:
The inscribed angle is half of the intercepted arc.
Multiply by 2 on both sides.
Substitute m∠NRQ = 60°.
The measure of minor arc NQ is 120°.
For simplicity, dy/dx means f'(x);
We have y = ( 8 - x^2 ) / 2x;
Then, y = 4/x - x/2;
So, f'(x) = (4/x - x/2)' = (4/x)' - (x/2)' = -4/(x^2) -1/2 because we use <span> d<span>ifferentiation formulas, such as : (f+g)' = f' + g'; (cf)' = cf'; x'=1; (1/x)' = -1/(x^2);
</span></span>Finally, f'(4) = -4/16 -1/2 = -4/16 - 8/16 = -12/16 = -3/4.
The correct answer is E.
15 is the length of the shorter leg
