Answer:
The population will be 896 turtles 6 years later ⇒ B
Step-by-step explanation:
The exponential increasing formula is y = a, where
- r is the rate of increase in decimal
∵ There are 300 turtles
∴ a = 300
∵ The population of the turtles exponentially increases 20% each year
∴ r = 20%
→ Divide it by 100 to change it to decimal
∵ 20% = 20 ÷ 100 = 0.2
∴ r = 0.2
∵ The time is 6 years
∴ x = 6
→ Substitute these values in the exponential formula above
∵ y = 300
∴ y = 300
∴ y = 895.7952
→ Round it to the nearest whole number
∴ y = 896
∴ The population will be 896 turtles 6 years later
Answer:
Alice is 6 1/9
Step-by-step explanation:
a is Alice and b is brother
a=4b-5
a=b-15
I prefer to use elimination
a=4b-5
-a=-b15
-3b=10
b=-10/3
a=4(10/3)-5
a=-55/3
Answer:
17/5
Step-by-step explanation:
3 and 2 out of 5...so 5 makes a whole
so 3 wholes or 3 5s is 15
15/5ths plus 2 fifths is 17 fifths or 17 over 5.
17/5ths.
Answer:
Step-by-step explanation:
<u>Given information</u>
f(x) = 3x² + x - 3
g(x) = 5x
<u>Given expression</u>
f(x) g(x)
<u>Substitute values into the given expression</u>
(3x² + x - 2) (5x)
<u>Expand the parenthesis by distributive property</u>
3x² · 5x + x · 5x - 2 · 5x
(3 · 5) (x² · x) + 5 (x · x) - (2 · 5) x
