Answer:
Last one: 3x²
Step-by-step explanation:
Quadratics are functions with the power of 2 as the highest.
Option 1 is a Reciprocal function
Option 2 is a linear function
Option 3 is a exponential function
Option 4 is a quadratic function
Answer:
1 13/20
Step-by-step explanation:
You add 2 1/10 and 3 to get 5 1/10. Then you subtract, 6 3/4 minus 5 1/10. If you want to find the least common factors you get 6 15/20 and 5 2/20 to make it easier to subtract. Finally, you get 1 13/20.
I hope this helped :)
It is B because if you use guess and check plug in 0 for all equations and only B matches with the function.

156
Step-by-step explanation:
Area of Base=length x width
Answer: The approximate total volume of the silo is 116.5 m3
Step-by-step explanation:
Hi, the volume of the silo is equal to: volume of the cylinder + volume of the hemisphere:
Volume of the cylinder:
V = π x r²x h
Where:
R = radius (in this case, to obtain the radius we have to divide the diameter by two since radius = diameter /2)
h = height
Replacing with the values given:
V = π x r²x h = 3.14 x (4.4/2) ²6.2= 3.14 x (2.2)²x 6.2 = 94.22512 m3
And for the hemisphere:
Volume of the hemisphere: 2/3 x π x r3
Replacing with the values given;
v= 2/3 x 3.14 x 2.2∧3= 22.28m3
Finally, adding both results:
Volume of the silo = volume of the cylinder + volume of the hemisphere:
94.22 m3+ 22.28m3 = 116.5 m3
