Answer:
Coffee = $2.00
Juice = $1.50
Doughnut = $1.00
Step-by-step explanation:
Given
Let:
So, we have:
Anna
Barry
Cathy
Required
The price of each
We have:
Make c the subject in:
Substitute in and
Make j the subject
Make j the subject
So, we have:
and
Equate both values of j
Collect like terms
Substitute in
To solve for c, we substitute in
Solve for c
5/3 % * x = 4.75
5/300 x =4.75
x = 4.75 * 300/5
x=4.75 * 60
x=285
volume of bigger: 8*8*8=512 s3
volume of smaller: 6.5*6.5*6.5=274.63 s3
difference: 512.00-274.63=237.37
The value x = - 2 is not part of the domain of the function f(x) = √(x + 1).
<h3>Is a given point part of the domain of a radical function?</h3>
Radical functions are functions that involves root operators. We see here a radical function of the form f(x) = √(x + a), whose domain is x ∈ [- a, + ∞), that is, x ≥ - a. If we know that f(x) = √(x + 1), then a = 1 and the domain of the function is x ∈ [- 1, + ∞), that is, x ≥ - 1.
Hence, the value x = - 2 is not part of the domain of the function f(x) = √(x + 1).
