Answer:

m = 24

Step-by-step explanation:

m + 7° + 2m + 11° = 90°

3m + 18° = 90°

3m = 90°- 18°

3m = 72

(divide both sides by 3)

therefore : m = 24

Answer:

a) No, Joe is not correct. Since the angle 2 is opposite to the angle that measures 72°, 2 measures 72°. Since 72° + 3 = 180°, angle 3 measures 108°.

b) Below that we have the exactly same thing: angles 5 and 7 measure 72°, and angles 4 and 6 measure 108°.

Find the area of the region bounded by the parabola y=5x2y=5x2, the tangent line to this parabola at (2,20)(2,20) and the xx axi

SIZIF [17.4K]

1. Find the equation of tangent line at point (2,20).

$y'=(5x^2)'=5\cdot 2x=10x,\\ \\y'(2)=10\cdot 2=20.$

The equation of the tangent line is

$y=20(x-2)+20,\\ \\y=20x-20.$

2. Express x:

$y=20x-20\Rightarrow x=\dfrac{y}{20}+1;\\ \\y=5x^2\Rightarrow x=\sqrt{\dfrac{y}{5}}.$

3. Find the area of bounded region:

$A=\int\limits^{20}_0 {\left(\dfrac{y}{20}+1-\sqrt{\dfrac{y}{5}} } \right)\, dy=\left(\dfrac{y^2}{40}+y-\dfrac{2\sqrt{y^3} }{3\sqrt{5} } \right)\big|^{20}_0=$
