Answer:

Step-by-step explanation:

Assuming that arc AB is where the inscribed angle meets the outside of the circle, then the rule is that the inscribed angle is 1/2 of the measure of its intercepted arc. For us,

$5x-7=\frac{1}{2}(2x)$

Solving for x:

2(5x - 7) = 2x so

10x - 14 = 2x and

8x = 14 so

x = 1.75

(a) Find the slope of the curve y= x^2 - 2x - 3 at the point P(2, -3) by finding the limit of the secant slopes through point

gayaneshka [121]

Answer:

Step-by-step explanation:

P=(2,-3)

Q=(a,a²-2a-3)

$\Delta y=a^2-2a-3-(-3)=a^2-2a\\\Delta x=a-2\\\\\displaystyle \lim_{a \to 2} \dfrac{a^2-2a-3-(-3)}{a-2} \\\\=\lim_{a \to 2} \dfrac{a^2-2a}{a-2} \\\\=\lim_{a \to 2} \dfrac{a(a-2)}{a-2} \\\\=\lim_{a \to 2} \dfrac{a}{1} \\\\=\lim_{a \to 2} a \\\\=2\\$
