The answer to (r -3s2t)4 is 4r- 24st
The domain is the set of input values for which the function is real and defined.
Find non negative values for the radicals.
For y = sqrt(3-x) if x is greater than the 3 the value under the square root would be negative which would result in a non real number.
The answer needs to be x <= 3 ( less than or equal to)
For y = sqrt(3x), if x is less than 0, the number under the sqrt root would be negative resulting in a non real number.
The answer is x >= 0 ( greater than or equal to)
PEMDAS!!
or an easy way to remember it is Please Excuse My Dear Aunt Sally
which stands for Parentheses, Exponent, Multiplication, Division, Addition, and Subtraction Go in order from p to s from left to right as you would read it
Parentheses first (9-3^2) start with the exponent 3^2=9 then subtract
(9-9)=0 so now we have 2+6(0)-2 Multiply next so 6(0)=0 then we have 2+0-2
next add 2+0=2 then we have 2-2 then subtract 2-2=0 so the overall answer is 0
but you have multiply, added, and subtracted throughout the process
Given :
Maximum capacity of fuel tank , M = 14 gallon .
It can travel approximately 26 miles with one gallon of gas.
To Find :
A function d(x), that gives the distance the Escape can travel with x gallons of gas in the tank.
Solution :
Car can travel 26 miles in one gallon of gas.
So , distance covered in x gallon of gas :
( Here, 0 ≤ x ≤ 14 ) or x ∈ [ 0 , 14 ] .
Hence , this is the required solution.
Answer:
31/40
Step-by-step explanation:
Find a common denominator
2/5= 16/40
3/8= 15/40
16/40+15/40= 31/40
