Answer:
Step-by-step explanation:
by theorem :
f continu in [1 , 2]
f(1)×f(2) < 0 because : f(1) = -1 and f(2) = 15
so the equation f(x)=0 has at least one real root between x=1 and x=2
so :
Hello! i can do the first word problem
first we need to divide 600/3 which is 200.
therefore we can infer that he does 200 letters an hour and we can solve the problem with this
200 x 7 = 1400 letters an hour
3 divided by 1 quarter is equal to 12 because
3 divided 1/4 is 12 . 1/4 is a quarter. so this is how you get your answer. 3 divide 1/4 = 3/1 multiply 4/1=12/1 =12
