Answer:
660 mm
Step-by-step explanation:
we know that
The scale factor is 
That means
1 unit in the model represent 15 units in the actual
or
1 m in the model represent 15 m in the actual
To find out the height of the model rocket, divide the height of the actual rocket by 15
so
Convert m to mm
Remember that
To convert meters to millimeters, multiply by 1,000
so
Answer:
i believe A
Step-by-step explanation:
Answer:
The Same shape so try that
Step-by-step explanation:
Answer:
x = ±(√y)/3
x = ±(√2)/3
Step-by-step explanation:
Put the given information in the given equation and solve for x:
f(x) = 2
2 = 9x^2 . . . . . use 2 in place of f(x)
2/9 = x^2 . . . . divide by 9
±√(2/9) = x . . . take the square root
x = ±(√2)/3 . . . simplify
_____
Using this as an example, we can solve f(x) = y in the same way:
y = 9x^2 . . . . use y for f(x)
y/9 = x^2 . . . divide by the coefficient of x^2
±√(y/9) = x . . . take the square root; next, simplify
x = ±(√y)/3 . . . . the equation solved for x. Note this matches the above when y=2.
the answer is david he is the one
