Shelby deposited $50 in a savings account earning 10% interest, compounded annually. To the nearest cent, how much will she have in 1 year?

$500

Step-by-step explanation:

I = PRT

I = (50)(10)(1)

I = 500

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
