Answer:
Step-by-step explanation:
Remark
The rate is going to be the same as the distance travelled in 1 hour. The units will be different.
Formula
d = r * t
Givens
d = 558 miles
t = 3 hours
Problem A
r = d / t
r = 558/ 3 = 186 miles / hr
Problem B
Givens
r = 186 miles / hour
t = 1 hour
d = ?
Solution
d = 186 mi/hr * 1 hr
d = 186 miles
<u>Note</u>
This looks really trivial, but it's not. You have to learn to see the difference between a number and its units. It's not very often that the numbers will be the same, but if the units differ, then it is an entirely different question.
Answer: i ^ 59 = -i
Step-by-step explanation:
If you recall when simplifying imaginary numbers
i^1 = i* 1 = i
i^2 = i*i = -1
i^3 = i*i*i = -i
i^4 = i*i*i*i = 1
i^5 = i^4 * i =i
i^6 = i^4 * i^2 = -1
etc... the 4 values keep repeating
so take the exponent and divide by 4, the remainder is how many i values you have left to get your simplified answer of i, -1,-i, or 1
Remainder 1 i
Remainder 2 -1
Remainder 3 -i
Remainder 0 1
Answer:
21785.1548486
Step-by-step explanation:
The growth rate is expressed by,
m'(t)=27t
when t=2days,
m'(2)=27*2
m'(2)=27*2
= 54*
= 21785.1548486
According to PEMDAS, these are the steps for evaluating this equation -
3-9=-6
-6 x 5 = -30 - 1 = -31
-31 x 6 = -186, + 2 = -184
Now our first answer is -184 (I think this is correct)
Next thing we'll do is the second equation
8-2 = 6
6 x 7 = 42
42 + 4 = 46
Now, we can divide :) -184 / 46 equals -4
Hope this helps :D!
Answer: A, B, C
Step-by-step explanation:
To solve for the inequality, we would solve it as if it had an equals sign.
[subtract both sides by 12]
[multiply both sides by -4/9, remember to flip inequality]
Now, we know that the solution is less than or equal to 80/9, which is approximately 8.89.
Looking at the answer choices, A, B and C are the answers since they are both less than 8.89.
