Answer:
I see there bo 957 ..
34 - 95 = - 61
a) 95 - 34 = 61
b) - 94 + (-34) = - 95 - 34 = -129
c) 34 - (-94) = 34 + 95 = 129
d) 34 + (-94) = 34 - 95 = -61
therefore, your answer is d
This is going to be hard but I'll try to figure it out may take a while
Answer:
(a)
(b) There will be 1lb left after 14 hours
Step-by-step explanation:
Solving (a): The equation
Since the substance decomposes at a proportional rate, then it follows the following equation
Where
Initial Amount
rate
time
Amount at time t
Solving (b):
We have:
First, we calculate k using:
This gives:
Substitute:
Divide both sides by 4
Take natural logarithm of both sides
This gives:
Solve for k
So, we have:
To calculate the time when 1 lb will remain, we have:
So, the equation becomes
Divide both sides by 8
Take natural logarithm of both sides
Solve for t
--- approximated
Answer:
SAS
Step-by-step explanation:
The sides have the same ratio and the angle between them is congruent, so it's SAS
The Geometric Mean<span> is a special type of average where we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. Below is the solution for the above problem:
</span>First we multiply them: 10 × 1250 = 12,500
Then (as there are two numbers) take the square root: √12,500<span> = </span>111.8034
