Answer:
You don't technically need the ( ) around the 2n, but I included them to avoid confusion.

Answer:
13. a = 6; b = 2
14. a = 3; b = 6
Step-by-step explanation:
The ratios of side lengths in a 30°-60°-90° triangle are ...
1 : √3 : 2
In ∆ABD, these are the ratios of sides ...
BD : AD : AB = 1 : √3 : 2
Since BD is given as 3√2, we can multiply these ratio values by that factor to get the actual side lengths:
BD : AD : AB = 3√2×1 : 3√2×√3 : 3√2×2
= 3√2 : 3√6 : 6√2
That is ...
13. AB = 6√2 ⇒ a=6, b=2
14: AD = 3√6 ⇒ a=3, b=6
This is an equation of exponential decay
y(t) = a b^ t where a is the initial amount
b is the decay factor
t is the time in years
b is found by taking 1 and subtracting the percent it decreases in decimal form
Letting t =4
y(t) = 260 million * ( 1- .011) ^ 4
=248.7473796 million
=24874737.96
Rounding to a whole number
= 24874738
The ship traveled <u>80 miles</u> in <u>4 hours</u> while the submarine traveled <u>75 miles</u> in <u>5 hours</u>.
<h3>How to determine the distance and time traveled?</h3>
Based on the information provided, we can logically deduce that the ship is initially 80 miles away from its destination. Thus, f(x) would be equal to 0, if it traveled 80 miles and 0 miles away from its destination:
f(x) = 80 - 20x
0 = 80 - 20x
20x = 80
x = 80/20
x = 4 hours.
By critically observing the graph (see attachment) for the submarine's voyage, we can logically deduce the following:
