Answer:

This is a 10 percent increase

Step-by-step explanation:

Last week he spent 10 hours

This week 11 hours

percent increase = (new - original )/original * 100 percent

                             = (11-10)/10 * 100 percent

                             = 1/10 * 100 percent

                             = 10%

This is a 10 percent increase

Oksana_A [137]

Answer:

At what point is the following function continuous?
liubo4ka [24]

Check the picture below.

something worth noticing           \bf \cfrac{x^2-x-6}{x-3}\implies \cfrac{(\underline{x-3})(x+2)}{\underline{x-3}}\implies x+2

so, we're really graphing x+2, with a hole at x = 3, however, when x = 3, we know that f(x) = 5, but but but, when x = 3, x+2 = 5, so we end up with a continuous line all the way, x ∈ ℝ, because the "hole" from the first subfunction, gets closed off by the second subfunction in the piece-wise.
