What are the coordinates of point B in the diagram?

Andrej [43]

Let the cordinates of B be (x, y), then
(3(1) + x)/4 = 1.75 and (3(5) + y)/4 = 2.5
3 + x = 7 and 15 + y = 10
x = 7 - 3 and y = 10 - 15
x = 4 and y = -5

Therefore, the coordinate of B is (4, -5)

A submarine cuts through the water at an elevation of 203 meters under the sea. The sub rises, and the elevation changes by 4.3

Natalija [7]

It should be 76.1m under water. First multiple 15x4.3=64.5, and 5.2x12=62.4. Add those together to get 126.9. Subtract that from the initial elevation of 203 and get your answer.

Bond [772]

Step-by-step explanation:

To write a polynomial in standard form, put the degree that are the greatest first

So here it would be

${x}^{5} + 4 {x}^{3} - 3 {x}^{2} + 10$
