Answer:

∠ ACE = 40°

Step-by-step explanation:

The sum of the angles in a circle = 360°, thus

arc AE = 360° - (112 + 28 + 112)° = 360° - 252° = 108°

∠ ACE is half the difference of the intercepted arcs, that is

∠ ACE = 0.5( arc AE - arc BD) = 0.5(108 - 28)° = 0.5 × 80° = 40°

Find the values of c such that the area of the region bounded by the parabola

KATRIN_1 [288]

<u>Solution-</u>

The two parabolas are,

$y=16x^2-c^2 \ and \ y=c^2-16x^2$

By solving the above two equations we calculate where the two parabolas meet,

$So \ 16x^2-c^2 = c^2-16x^2 \Rightarrow 32x^2=2c^2 \Rightarrow x=\frac{1}{4}c$

Given the symmetry, the area bounded by the two parabolas is twice the area bounded by either parabola with the x-axis.

$\therefore Area=2\int_{-c}^{c}y.dx= 2\int_{-c}^{c}(16x^2-c^2).dx\\=2[\frac{16}{3}x^3-c^2x]_{-c}^{ \ c}=2[(\frac{16}{3}c^3-c^3)-(-\frac{16}{3}c^3+c^3)]=2[\frac{32}{3}c^3-2c^3]=2(\frac{26c^3}{3})\\=\frac{52c^3}{3}$

$So \frac{52c^3}{3}=\frac{250}{3}\Rightarrow c=\sqrt[3]{\frac{250}{52}}=1.68$
