Answer: the answer is an equation
Step-by-step explanation:
The length of a pendulum that makes one full swing in 1.9 s is about 2.926 which is about 3ft when rounded to the nearest foot
Answer:
![\boxed {\boxed {\sf D. \ f(3)= 30}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%5Cboxed%20%7B%5Csf%20D.%20%5C%20f%283%29%3D%2030%7D%7D)
Step-by-step explanation:
We are given the function:
![f(x)= 3(2)^x+6](https://tex.z-dn.net/?f=f%28x%29%3D%203%282%29%5Ex%2B6)
We want to find f(3), so we must substitute 3 in for x.
![f(3)= 3(2)^3+6](https://tex.z-dn.net/?f=f%283%29%3D%203%282%29%5E3%2B6)
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Solve the exponent first.
![f(3)= 3(8)+6](https://tex.z-dn.net/?f=f%283%29%3D%203%288%29%2B6)
Multiply 8 and 3.
![f(3)= 24+6](https://tex.z-dn.net/?f=f%283%29%3D%2024%2B6)
Add.
![f(3)=30](https://tex.z-dn.net/?f=f%283%29%3D30)
For the function given, f(3) is 30.
Answer:
The slope- intercept form this situation is given by y = 0.75x + 3 .
Step-by-step explanation:
The slope- intercept is given by
y = mx + c
Where m is the slope, c is the y intercept .
As given
When visiting Baltimore, MD needs taxi to get from your hotel to the National Aquarium.
The taxi company charges a flat fee of $3.00 for using the taxi and $0.75 per mile.
Let us assume that the total amount charge by the taxi be y .
Let us assume that the number of miles travelled by the taxi be x.
Than
Total amount charge by taxi = Amount charge by the taxi per miles + Flat free charge .
y = 0.75x + 3
(Here m = 0.75 and c = 3)
Therefore the slope- intercept form this situation is given by y = 0.75x + 3 .
