Answer:
Step-by-step explanation:
Decreasing rate = 12% = 0.12
y = 2400 * (1- 0.12)^x = 2400*(0.88)^x
x = 8 years
b = 21
In this problem, we aren't finding the hypotenuse, but a side...
Using Pythagoras' theorem
side² = hyp² – side²
b² = 29² – 20²
b² = 841 – 400
b² = 441
b² = √441
b = 21
Therefore b = 21

Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Linear equations are typically organized in slope-intercept form: where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
- Perpendicular lines always have slopes that are negative reciprocals of each other (ex. -1/3 and 3, 1/2 and -2, etc.)
<u>1) Determine the slope (m)</u>
Looking at the given equation, we can identify clearly that is in the place of m, making it the slope of the line. Because perpendicular lines always have slopes that are negative reciprocals, we know that the slope of the line we're solving for will be . Plug this into :
<u>2) Determine the y-intercept (b)</u>
Plug in the given point (-3,5)
Subtract 4 from both sides
Therefore, the y-intercept is 1. Plug this back into :

To find the fraction inbetween,
1. Add up the 2 fractions
2 Divide it by 2
Step (!) Add them up:
2/3 + 1 1/3 = 2
Step (2) Divide the answer by 2:
2÷ 2 = 1
Answer: The number between 2/3 and 1 1/3 is 1.
