Answer:
- f(x) is negative when x < 9
- f(x) is increasing when x < 1
- The x-intercept is 9
Step-by-step explanation:
The function is
f(y) = (y + 2)³ + 1
Answer:
8.49 × 10⁻³
Explanation:
Standard form of a number: A. × 10ᵇ
(where 'A' is the number, b is the exponent over 10)
For the number "0.00849", move the decimal point 3 places right so the exponent of 10 is -3.
Standard form: 8.49 × 10⁻³
Other examples of standard/scientific forms are: standard forms
i) 0.043, move the decimal point 2 places right = 4.3 × 10⁻²
ii) 4030, move the decimal point 3 places left = 4.03 × 10³
Answer:
I know that solutions of a system has different kinds of ways on how to fix the problem.
Step-by-step explanation:
Answer:
8 salt water
7 fresh water
Step-by-step explanation:
Let's represent salt water fish with the variable "s" and fresh water fish with the variable "f".
We can make a system of equations - one equation for the number of fish and the other for the price of the fish.
We know that the total number of fish Laura has is 15, and the total price of the fish was $23.
Solve the system of equations by subtracting the bottom equation from the top equation.
Laura bought 8 salt water fish. Since the total number of fish is 15, the number of fresh water fish must be 7.
I've attached a picture below of the formula for a
finite geometric sequence. It includes an
infinite geometric sequence formula for your reference, too.
Plug in the values.
