Put the number in the formula and do the arithmetic.
C = (5/9)(329 - 32)
C = (5/9)(297)
C = 165
The temperature in °C is 165.
A rational number is a number that can be written into a fraction. pi, some square roots, e, etc., are irrational numbers(numbers that cannot be written into a fraction).
412 + 162 + 347 = 921. Because it is closer to 900 than 1,000, the answer is 900.
f(x) is a multiple of the cosine function. g(x) is a multiple of the sine function. Both the cosine function and the sine function have a maximum value of 1, so the magnitude of the multiple will determine which function has the largest maximum value.
The multiple for f is 2; the multiple for g is 3, which is greater than 2. Hence g(x) has a larger maximum value than f(x).
