Answer:
Ans: greater than 40 mileage Company A will charge less than Company B
Step-by-step explanation:
as company A charges a fix amount $93 for any distance and company B charges variable amount starting from $65.there will be a certain mileage after that the amount charged by company B should be greater than company A.
let for greater than m mileage company A will
charge less than company B.
charge for company A for m mileage= $93
charge for company B for m mileage= $65 + $0.70*m
so,
93 ≤ 65+0.70*m
93-65 ≤ 65+0.70*m -65
28 ≤ 0.70*m
28*10 ≤ 7 *m
280 ≤ 7m
280/7 ≤ 7m/7
40 ≤ m
Answer:
D. A withdrawal of $30 from a bank account
Step-by-step explanation:
When it says magnitude it doesn't matter if it's a positive or negative number.
So it's just asking which number is the greatest which is 30.
I hope my explanation makes sense and helps you out.
Answer:
In my sketch the angle between their flights is 135°
So wouldn't we just have the cosine law??
Step-by-step explanation:
x^2 = 120^2 + 150^2 - 2(120)(150)cos135°
carry on, take care with the cos135, since it will be negative
When talking about Algebra, a term is a single number or a variable (or both). Terms are usually separated by + or - signs! In this expression, there are 3 terms.
The numbers/variables in bold show the terms:
x^4-3x+2

Answer:
-1
Step-by-step explanation:
First, we need to find which expression to use for f(1). The first function does not include 1, because it is <, and not 
The second functions includes 1, because it has a , meaning greater than or equal to, so this is the function we must use.
-x^2
Plug 1 in for x
-(1^2)
Solve the exponent first
-(1)
-1
So, f(1)=-1
