Write the following as a base-10 numeral in standard form.
4 x 105 + 2 x 102 + 7 =

9514 1404 393

  400207

Step-by-step explanation:

Any calculator can form this sum for you. It is ...

  4×10^5 +2×10^2 +7

  = 400,000 +200 +7

  = 400207

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3

step-by-step explanation:

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
