In triangle RST, RT = 12 cm, ST = 12 cm and angle RST = 90 degrees calculate the length of RS, giving your answer correct to one decimal place.

Step-by-step explanation:

RS=SQUARD ROOT ((RT) SQUARED+ (ST) SQUARED)

RT =12 SQUARED= 144 ST SQUARED= 144, ADD TOGETHER EQUALS 288.

SQUARE ROOT OFF 288 EQUALS 16.95 RS = 16.9

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
