Answer:
Q1
<u>The exponential growth model for frogs:</u>
F- number of frogs, x- number of years, 1.22 - growth factor
<u>Calculations</u>:
- F(5) = 100(1.22)⁵ = 270
- a) F(10) = 100(1.22)¹⁰ = 730
- b) F(20) = 100(1.22)²⁰ = 5335
<em>All numbers rounded </em>
Q2
<u>The exponential growth model for bacteria:</u>
B- number of bacteria, x- number of hours, 1.8 - growth factor
<u>Calculations:</u>
- a) B(5) = 10(1.8)⁵ = 189
- b) B(24) = 10(1.8)²⁴ = 13382588
- c) B(168) = 10(1.8)¹⁶⁸ = 7.68 * 10⁴³

Q3.
<u>The exponential growth model for fish:</u>
F- number of fish, x- number of months, 1.02 - growth factor
<u>Calculations:</u>
- a) F(12) = 821(1.02)¹² = 1041
- b) F(120) = 821(1.02)¹²⁰ = 8838
<em>All numbers rounded </em>
475 songs- 380 songs= 95 songs
95 songs/ 475 songs* 100%= 20%
The percent error is 20%~
Answer:
Blue Line: y = 4x - 1
Green Line: y = -x + 6
Red Line: y = -x
Step-by-step explanation:
Looking at the equation y = mx + b
- The first giveaway is that the green line is the highest y-intercept (b- value). So we can say it's y = -x + 6
- Second giveaway is that the blue line has the lowest y-intercept (again the b- value). So we can say it's y = 4x - 1
- Third giveaway is that the red line has the same x-intercept AND y-intercept which is y = -x. Both intercepts are (0, 0).
Lastly, the rest of the statements are true in correspondence of the last 3 statements.
