K = y/x
k = 30/2
k = 15 <=== constant of proportionality
Answer:
18?
Step-by-step explanation:
15x.2=3 (20% of 15)
15+3=18
So new bar is 18 cm
Not really sure but I think lol
Answer:
Square root ( 2 )
Step-by-step explanation:
We have to determine which value is equivalent to | f ( i ) | if the function is: f ( x ) = 1 - x. We know that for the complex number: z = a + b i , the absolute value is: | z | = sqrt( a^2 + b^2 ). In this case: | f ( i )| = | 1 - i |. So: a = 1, b = - 1. | f ( i ) | = sqrt ( 1^2 + ( - 1 )^2) = sqrt ( 1 + 1 ) = sqrt ( 2 ).
The last one is no solutions and the first on is <span>infinitely many solutions
and the second one is one solution. I am pretty sure! Hope this helps!</span>
Answer: 1 inch = 20 feet
Step-by-step explanation: You can answer this question using Unit Rate. Khan Academy explains it better, but basically you take the ten inches and divide it by ten to get one. and to get the scale, you have to divide 200 by ten to get the unit rate where 1 inch equals 20 feet.
