the surface area is 160 cm
Answer:
22.5
Step-by-step explanation:
A=1/2 times base times height
Okay so, I am assuming the model is smaller so it would be 0.34m long.
The model has to be 200 times smaller than the actual plane
Divide 68/200 and you get 0.34
Then to check your answer, multiply 0.34 by 200 which is 68 meaning
0.34:68 is equal to 1:200
Assuming the model is bigger (just in case) it would be 13,600m long.
The in this scenario, the model has to be 200 times bigger so it would be 68(200) which is 13,600
Hope this helps
The closed to the answer is C
Answer:
All real numbers
Step-by-step explanation:
Assuming the polynomial is

Then the domain is all real numbers.
The domain are all values of x, for which the given function is defined.
The reason is that, polynomials are defined everywhere on the real number line.
We can write this as {x|x is all real numbers} .
Or (-∞,+∞)
