Pipe with an OD of 6.03 cm and an ID of 4.93 cm carries steam at 250◦C. The pipe is cov- ered with 2.5 cm of magnesia (85%) insulation followed by 2.5 cm of polystyrene insulation (k = 0.025 W/m · K). The temperature of the exterior surface of the polystyrene is 25◦C.

Mr. walker gave his class the function f(x) = (x + 3)(x + 5). four students made a claim about the function. each student’s claim is below. jeremiah: the y-intercept is at (15, 0). lindsay: the x-intercepts are at (–3, 0) and (5, 0). stephen: the vertex is at (–4, –1). alexis: the midpoint between the x-intercepts is at (4, 0). which student’s claim about the function is correct?

Find x to the nearest hundredth place

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.
