ABC and DEC are right triangles with night angles and respectively DE = 6EC = 18 and BE = 12 find the area of triangle ABCNote that the triangle may not be drawn scale)

A particle is moving with acceleration a(t) = 36t + 8 . Its position at time t = 0 is s(0) = 3  and its velocity at time t = 0 is v(0) = 1 . What is its position at time t = 8 ?

Find the smallest integer a such that the Intermediate Value Theorem guarantees that f(x) has a zero on the interval [0,a].f(x)=−3x3+8x2−4x+4

4.5 is what percentage of 17.5

If the bottom of the ladder slides away from the wall at a rate of 1.2 ft/s, how fast is the angle between the ladder and the ground changing when the bottom of the ladder is 8 ft from the wall?

Consider the linear system with 4 unknown variables x1, x2, x3, x4 and 4 equations.x1 + x2 - bx3 + (b-a)x4 = b-2x1 + ax2 - bx3 = 12x1 + 2x2 + ax4 = 0x1 + x2 - bx3 = 0for some real numbers a, b =... more
