Answer:
part A 210 Part B 4.4
Step-by-step explanation:
PART A 42 TIMES 5 210
that will be the rate she ran.
PART B 1.1 times 4 that will be the minute.
Answer:
Step-by-step explanation:
Slope of line through (5,4) and (3,7) = (7-4)/(3-5) = -1.5
Point-slope equation of line:
y-4 = -1.5(x-5)
Convert equation to standard form:
y-4 = -1.5x + 7.5
1.5x + y = 11.5
3x +2y = 23
With my calculations im thinking 120 students
Write
, and recall that for a differentiable function
, the derivative at a point
is given by
which would suggest that for this limit,
and
. We have
, and so the value of the limit would be
.
11
(9, 18, 27, 36, 45, 54, 63, 72, 81, 90 and 99)
Those numbers divisible by 9 are the multiple of 9; thus need to know how many multiples of 9 there are between 1 and 100:
100 ÷ 9 = 11 r 1 ÷ last multiple of 9 is 11 × 9 (= 99)
→ There are 11 - 1 + 1 = 11 numbers between 1 and 100 which are divisible by 9.
(They are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.)
