Answer:
t = 6.3
Step-by-step explanation:
N=Noe^(-kt)
No = 14 grams
k = .1092
We want to find t when N = 7 or 1/2 of 14
N=Noe^(-kt)
7 = 14 e ^ (-.1092t)
Divide each side by 14
1/2 = e ^ (-.1092t)
take the natural log of each side
ln (1/2) = ln e ^ (-.1092t)
ln (1/2) = -.1092t
Divide each side by -.1092
ln (1/2)/ -.1092 = t
t≈6.3475
Rounding to the nearest tenth
t = 6.3
It’s correct. i like your handwriting btw, it’s really pretty
0.48
12/25
add a 0 and a decimal then you will see then number goes with 4 then 8 there is your answer.
Answer:
The cosine of the angle is <u>positive</u>
The sine of the angle is <u>negative</u>
Step-by-step explanation:
We are given that
angle lies in fourth quadrant
and we know that
In first quadrant:
sin is positive
cos is positive
In second quadrant:
sin is positive
cos is negative
In third quadrant:
sin is negative
cos is negative
in fourth quadrant , cosine of angle is always positive
and sine of angle is always negative
so,
The cosine of the angle is <u>positive</u>
The sine of the angle is <u>negative</u>
Answer: Hey there, your answer is 1/12
Step-by-step explanation: Steps to solve (steps will be in numerical order)
1. Find the lcd of the fractions, and the lcd for both problems will be 12.
2. To rewrite you have to multiply the numerator and denominator by three since the lcd is 12. So you're new fraction will be . For the second fraction, since the lcd is 12 you will multiply the numerator and denominator by 4. You're new fraction will be .
3. Since the problem contains the math keyword "Further", you automatically know you have to subtract, now subtract - . First, start of by subtracting the numerators, so subtract 9-8=1 , remember the denominators will always stay the same.
In conclusion, you're answer will be , so Isabel lives farther away from Janet.
Hope This Helps :)
