Answer:
Domain: all real numbers. Range: (-∞, 2000]
Step-by-step explanation:
f(x)=2.5x is a simple "ramp" function, a linear function and a polynomial. As such, its domain contains "all real numbers." That value 800 defines the largest value that this f(x) can have: f(800) = 2.5(800) = 2000.
Thus, the range is "all real numbers from -∞ through and including 2000."
Answer:
Yes
Step-by-step explanation:
There are 10 mm in 1 cm.
We have 300 mm, so let's convert this to cm by using a proportion:
, where x is the number of cm in 300 mm.
Cross-multiplying, we get: 10x = 300, so x = 30 cm.
Clearly, 30 cm > 3 cm, so yes, 300 mm is greater than 3 cm.
Hope this helps!

Answer:
144 ways
Step-by-step explanation:
Number of paintings = 7
Renaissance = 4
Baroque = 3
We are hanging from left to right and we will first hang Renaissance painting before baroque painting.
For Renaissance we have 4! Ways of doing so. 4 x3x2x1 = 24
For baroque we have 3! Ways of doing so. 3x2x1 = 6
We have 4!ways x 3!ways
= (4x3x2x1) * (3x2x1) ways
= 144 ways
Therefore we have 144 ways to hang the painting.
