Step-by-step explanation:
Which of the ten basic functions in
our toolkit have an infinite number of
local extrema?
a) cos(x), 2
b) sin(x), cos(x)
c) In(x), cos(x)
d) sin(x), x2
Answer:c
Step-by-step explanation:
For this case what we must do is find the speed of Esmeralda.
For this, we look for the rate of change of the function
We have then:
Substituting values:
Rewriting:
Answer:
Esmeralda's average rate during her trip is 5 miles per hour.
Answer:
Step-by-step explanation:
Out of 30 numbers, half is multiple of 2 and the third is multiple of 3.
We have 15 even numbers and 10 multiples of 3. Out of 10, half is even numbers and therefore counted twice.
<u>So we subtract 5 to get:</u>
<u>If we chose one ticket at random the probability is:</u>
- P(2x or 3x) = 20/30 = 2/3 or 66.66%
Answer:
5(2x-8)+15=-15
10x-40+15=-15
10x-25=-15
+25 +25 (add 25 to both sides)
____________
10x=10
divide by 10 on both sides
x=1
