Answer:
D. 1/2
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Standard form is written according to the highest exponent on the variable to the lowest. This expression has exponents that descend from 8 to 7 and to 1. B is the correct solution.
Answer:
Function:
c = f(w) = 0.49, 0 < w ≤ 1
= 0.70, 1 < w ≤ 2
= 0.91, 2 < w ≤ 3
Step-by-step explanation:
Yes, the relation described can be interpreted as a function.
Here, c is the cost of a mail letter. c depends upon w, which is the weights of the mail letter.
As described in the question, the relation can be expressed as a function.
c can be expressed as a function of w in the following manner:
c(cost of mail) = f(w), where w is the independent variable and c is the dependent variable
c = f(w) = 0.49, 0 < w ≤ 1
= 0.70, 1 < w ≤ 2
= 0.91, 2 < w ≤ 3
where, c is in dollars and w is in ounces.
Answer:
The provided statement is TRUE.
Step-by-step explanation:
The function <em>f</em> is an expression in variable <em>x</em>.
The entire expression can either be denoted by f (x) or <em>y</em>.
For instance consider the quadratic expression:
f (x) = ax² + bx + c
≡ y = ax² + bx + c
So, on computing the value of f (2), it implies that we are computing the value of y for <em>x</em> = 2.
Thus, the provided statement is TRUE.
