Generic exponential growth model: y = Ao[1+r]^t
In this case: r = 3.5% = 0.035
y = 2Ao .....[the double of the initial value]
Then: 2Ao =Ao (1 + 0.035)^t
(1.035)^t =2
Take logarithm to both sides
t ln(1.035) = ln(2)
t = ln(2) / ln(1.035) = 0.693 / 0.0344 = 20.15
Answer: 20.15 hours.
Answer:
10x-3
Step-by-step explanation:
I believe its 31/100! <span>To write 0.3111 as a fraction you have to write 0.3111 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.</span>
Answer:
4a - 20b - 3c
Step-by-step explanation:
6a - 5b - 8c - 15b - 2a + 5c
= 4a - 20b - 3c
D. 330 ft2
Explanation:
Find the area of the whole carpet first:
Multiply 24 x 14 = 336 square feet. I got the length 24 cause look at the measurement at the top, its 20 and 4 so add those together.
Then find the area of that one corner of the carpet that will be excluded:
The figure it makes is a triangle, so this is how u find the area:
3 x 4 divided by 2 = 6 square feet.
Minus 336 - 6= 330
Cha.t me if u have any questions.
I believe in my answer, trust me this is easy geometry-
Mark me brainliest!
