Hi there,
Sol:
Length of the swimming pool = 260 m
Breadth of the swimming pool = 140 m
Let the height of the water in the swimming pool after pouring water be h meters.
Volume of the water poured = 54600 m3
l x b x h = 54600
260 x 140 x h = 54600
h = (54600) / (260 x 140)
h = 1.5 m = 150 cm
Hope it helps
The answer is 64x^2+114x+81. Hope this helps.
x= -0.25 and 1.25
x = -0.5 and 1.5
x = 0 and 1
x = -0.375 and 1.625
Step-by-step explanation:
Given equation of the curve is
![y = 4x^2 -4x-1](https://tex.z-dn.net/?f=y%20%3D%204x%5E2%20-4x-1)
(i)
First equation ![4x^2 -4x-1 =0](https://tex.z-dn.net/?f=4x%5E2%20-4x-1%20%3D0)
Here y = 0
In x-axis the value of y = 0
The graph cuts the x-axis at(-0.25,0) and (1.25,0)
So, x= -0.25 and 1.25
(ii)
![4x^2 -4x-1 =2](https://tex.z-dn.net/?f=4x%5E2%20-4x-1%20%3D2)
here y = 2
The line y= 2 cuts the curve at (-0.5,2) and (1.5,2)
So, x = -0.5 and 1.5
Given equation of the curve is
![y= 3x^2-3x -1](https://tex.z-dn.net/?f=y%3D%203x%5E2-3x%20-1)
(i)
![3x^2-3x +2 =2](https://tex.z-dn.net/?f=3x%5E2-3x%20%2B2%20%3D2)
![\Leftrightarrow 3x^2-3x -1 = -1](https://tex.z-dn.net/?f=%5CLeftrightarrow%20%203x%5E2-3x%20-1%20%3D%20-1)
Here y = -1
The line y = -1 cuts the curve at (0,-1) and (1,-1)
So x = 0 and 1
(ii)
![3x^2-3x -1 =x+1](https://tex.z-dn.net/?f=3x%5E2-3x%20-1%20%3Dx%2B1)
Here y = x+1
The line y -x =1 cuts the curve at (-0.375,0.5) and (1.625,2).
So x = -0.375 and 1.625
Answer:
$98100
Step-by-step explanation:
Using the given formula :
I = P × R × T
I = 90000 × 3/100 × 3
I = $8100
He saves = 8100 + 90000 = $98100
You’d have to buy 3 shirts, with the 20% off the shirts would come out to $14.39. So $14.39 x 3 = $43.17. Now with the $10 off a $40 purchase your total cost would be $33.17.
