The area for semi circle is: (pi)(r^2)/2
A= 3.142 x (8.2)^2 / 2
A= 110.8 cm^2
2 times a number minus 9 is less than or equal to 21. and in inequality form that’s: 2x - 9 >_ 21 and u make a number line and a closed circle on 15 and an arrow going right. i hope i understood your question right
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."
1 meter equals 1000 millimeters
to convert meters to millimeters multiply the known meters by 1000
8.5 meters x 1000 = 8500 millimeters
