In the figure, $m\angle AED\ =\ 34$ ° and $m\angle EAD\ =\ 112$ °. Two triangles E A D and D B C, sharing a common vertex D, are drawn side-by-side. Points E, D and C are forming a horizontal line segment. Angle E A D, angle A D B, and angle D B C are congruent. Angle A E D, angle A D E, angle B D C, and angle B C D are congruent.

Find $m\angle BDC$

$m\angle BDC\ =\ $
°

Mathematics

48 objects

Step-by-step explanation:

we have

$t=0.003x^{2}+0.001x$

where

t is the number of seconds

x is the number of objects

For t=7 sec

substitute in the equation and solve for x

$7=0.003x^{2}+0.001x$

Solve the quadratic equation by graphing

The solution is x=48 objects

see the attached figure

Acomputer can sort x objects in t seconds, as modeled by the function below: t=0.003x^2 +0.001x how
