Answer: linear function is any function that graphs to a straight line. What this means mathematically is that the function has either one or two variables with no exponents or powers. If the function has more variables, the variables must be constants or known variables for the function to remain a linear function.
Step-by-step explanation:
Trapezoid : A= (a+b/2)h
a and b are the bases of the trapezoid
h is the height
kite: A= pq/2
p is the diagonal
q is the other diagonal
Answer:
f(-2)=27
Step-by-step explanation:
Plug in -2 into x
f(-2)=2(-2)^2-8(-2)+3
f(-2)=8+16+3
f(-2)=27
Answer: x=12.37 (2 decimal place) and the second box is √153
Step-by-step explanation:
You would have to use pythagoras theorem.
The formula for the short side is x²=c²-b²
The formula with the numbers in it is x²=13²-4²
13²=169
4²=16
x²=169-16
x²=153
To find x on its own you would have to square root 153.
x=12.37 (2 decimal places)
Hope this helps :)
