Answer:
The table represents a function.
What is the value of f(-1)?
f(-1) = - 3
f(-1) = -1
f(-1) = 0
f(-1) = 6
Step-by-step explanation:
6! = 6 * 5 *4*3*2*1 =720
8p5 = 8*7*6*5*4 = 6720
12C4 = (12p4)/4! = (12*11*10*9)/4*3*2*1 = 495
Proportional... 4/5 so are there more red or green, you need to answer that question first, then you can line up that answer with how many there are and butterfly it. Ex:
4/5. 4 red to 1 green
11/16. 11 red to 5 green
It’s really just subtracting
If one inch equals 10 meters, then multiply each inch by 10 to get the real dimensions (in meters)
6 * 10 = 60
8 * 10 = 80
Then multiply the length of the sides to get the area
60 * 80 = 4800 meters squared.
Answer:
h = 20 cm
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2) *h
where b1 and b2 are the two bases
We are given a =400 and b1 =27 and b2 =13
400 = 1/2 (27+13) *h
400 = 1/2 (40) *h
400 = 20h
Divide each side by 20
400/20 = 20h/20
20 =h
