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:
Inequality Form: x > 17
Interval Notation: (17, ∞)
3x3x3x5x5 is in nonstandard form. Please, use " ^ " to denote exponentiation:
3x^3x^3x^5x^5.
Noting that a^b*a^c = a^(b+c), rewrite 3x^3x^3x^5x^5 as 3x^(3+3+5+5) = 3x^16.
Answer:
Perimeter ratio = 2:1
Area ratio = 4:1
Step-by-step explanation:
<u>Perimeter</u>
Perimeter of the smaller photo = 

inches
Perimeter of larger photo = 

inches
Ratio:
Perimeter of larger photo : perimeter of smaller photo = 

<u>Area</u>
Area of smaller photo = 

inches²
Area of larger photo = 

inches ²
Ratio
Area of larger photo : area of smaller photo = 

∴The ratio of the perimeters = 2:1, and the ratio of the areas = 4:1
Hope this helps :)
