Answer:
2441.95 years
Step-by-step explanation:
We can model this exponencial function as:
P = Po * (1+r)^(t/n)
Where P is the final value, Po is the inicial value, r is the rate, t is the time and n is the period of half-life.
In this case, we have that P/Po = 100% - 25.5% = 74.5% = 0.745, r = -0.5 and n = 5750, so we have that:
0.745 = (1 - 0.5)^(t/5750)
Step 1: log in both sides:
log(0.745) = (t/5750) * log(0.5)
Step 2: isolate t
t = 5750*log(0.745)/log(0.5) = 2441.95 years
Answer: Mark is 14 and Jim is 7.
Step-by-step explanation: It says that next year Mark will be threee times older than Jim was 2 years ago.
The wrk is:
7-2=5(Jims age 2 years ago)
5x3=15
15-1=14(you subtract 1 because Mark's current age is 14 because it says that next year it will be 3 times Jim's)
Answer:
inverse of sin 1.6
or it can be written as sin^1 1.6
Answer:
60
Step-by-step explanation:
Since the angles A, D, and G are congruent then sum of given angles is eaqual to 180 degrees
x + 20 + 2x + x = 180 add like terms
4x + 20 = 180 subtract 20 from both sides
4x = 160 divide both sides by 4
x = 40
Angles B, E, and H are congruent so E is also = x + 20 and x = 40 so angle R = 60
