Answer:
60 cm ( squared )
Step-by-step explanation:
you can find the area of the trapezoid ( by decomposing it into other shapes ) by separating two triangles, and using the formula to find the area of triangles, which is A= 1/2 ( b x h ) and add the answer to those together ( 16 cm squared and 4 cm squared ), and after that, you can find the area to the rectangle by multiplying the l x w, which is 10 x 4 ( after separating the triangles.). That equals 40, and when you add them all together ( 16 + 4 + 40 ) it equals 60 cm (squared).
Well on a table of data, if the y coordinates increase a lot over a short x distance then it will be steep.
In an equation, you would put it into y = mx + b form and whatever your m is will be your slope. If m is large, it will be steep.
To find f(4), you just replace wherever x is with 4.
f(x) = 3x - 1
⇒ f(4) = 3*(4) - 1
⇒ f(4)= 12-1
⇒ f(4)= 11.
f(4) = 11 is the final answer.
