Michael has a summer job as a bricklayer’s assistant. He is responsible for mixing the concrete. concrete is made of cement, sand, and gravel in a ratio of 1:3:4 by mass. michael needs to make 80 kg of concrete.

For g(x) = 5x - 3 and h(x) = [tex]\sqrt{x}[/tex], find (g · h)(4)

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.

Select the correct answer and solve for y
