24-2+2=24
Answer: 
Step-by-step explanation:
The exponential function h, represented in the table, can be written as 
From table, at x=0, h(x) =10
Put theses values in equation,, we get

Also, for x= 1 , h(x) = 4, so put these values and a=10 in the equation , we get

Put value of a and b in the equation ,
→ Required equation.
30-5*4+2
30-20+2
10+2
12 is the answer
Answer:
= 18 cm^3
Step-by-step explanation:
V = Bh where B is the area of the base, which is the triangular face
B = 1/2 (4*3) = 6
V = 6* 3
V = 18 cm^3
