Answer:
-1/4x² + 3
Step-by-step explanation:
Given that:
Path of sprinkler is modeled by the quadratic function :
w(x) = -1/4(x^2 -12 )
w(x) = height of the water, in meters, at position x
The height of ceiling as a constant or Coefficient = w(x)
Expanding w(x)
-1/4(x^2 -12 )
-1/4 * x² + 1/4 * 12
-1/4x² + 3
The height of ceiling is -1/4x² + 3
Answer:
HCF=3
Step-by-step explanation:
Factors of 15t= 3*5*t
Factors of 6s= 2*3*s
HCF= Common factors
common factor = 3
HCF=3
Answer:
Step-by-step explanation:
Let the numbers be x and y.
<u>We have:</u>
<u>Sum the two and find x:</u>
<u>Find y:</u>
It would be .5x-5= because it says 5 less so it would be subtract 5 from half of x.
First, the difference is 7/2 - 6/4 = 14/4 - 6/4 = 8/4
Now multiply it: 8/4 x (-2/5) = -16/20 = -4/5
