Answer: lenght is 50yrds, width is 30yrds
Step-by-step explanation:
Perimeter of a pool = 2( lenght x breadth)
Perimeter = 160yrds
If the lenght is 10yrds less than twice the width then,
lenght = 2w - 10,
Where w is the width
Then from p = 2(L + w)
160 = 2( 2w - 10 + w)
160 = 2(3w - 10)
160 = 6w - 20
160 + 20 = 6w = 180
width w = 180/6 = 30yrds
From p = 2(L + w)
160 = 2(L + 30)
160 = 2L + 60
160 - 60 = 2L = 100
L = 100/2 = 50yrds
Hmmm the y-intercept is at -2? what does that mean? well, is where the graph "intercepts" or touches the y-axis, and when that happens, x = 0, so the point is really ( 0 , -2 ).
and we know where the vertex is at. Let's assume a vertical parabola, in which case the squared variable is the "x".
The answer will be B.exponential
Answer:
125
Step-by-step explanation:
The ratio is 5:3 so we divide the 75 by 3 to get 1 part
1 part = 75
75 x 5 = 125
