Answer:
The domain and range of this relationship is (-∞,∞) and (-∞,∞) respectively.
Step-by-step explanation:
We are given that Carly is traveling to visit family.
She drive distance on first day = x
She drive distance on second day = y
We are also given that Carly is travelling a total of 800 miles.
So,x+y=800
We are supposed to find domain and range of this relationship.
y=800-x
Domain : (-∞,∞)
Range:(-∞,∞)
Hence the domain and range of this relationship is (-∞,∞) and (-∞,∞) respectively.
Answer:
domain: 0 ≤ x ≤ 800
range: 0 ≤ y ≤ 800
Step-by-step explanation:
Cos^2(81°) - sin^2(81°)
Answer:
= (162°)
Step-by-step explanation:
(81°) - (81°)
we know that;
(x°) - (x°) = (2x°)
(81°) - (81°) = (2 * 81°)
= (162°)
The value of expression 350 /10³ is 0.35
An expression is a set of terms combined using the operations +, -, x or ÷, for example 4 x − 3 or 5 x 2 − 3 x y + 17 . An equation is a statement with an equals sign, which states that two expressions are equal in value, for example 4 b − 2 = 6 .
given statement:
350 divided by 10 to the power of 3
Now,
350 /10³
=350/1000
=0.350
=0.35
Hence, the value of expression is 0.35
