There is a line through the origin that divides the region bounded by the parabola and the x-axis into two regions with equal ar
jasenka [17]

Using the slope line formula,

The slope of line y = mx is 1.0315.

We have given that,

parabola equation is y = 5x - 3x²

line passing through origin is in the form of y = mx

==> mx = 5x - 3x²

==> 3x²+ mx - 5x = 0

==> 3x² + x(m -5) = 0

==> x(3x + (m -5)) = 0

==> x = 0 , x = (5 -m)/3

The total area of the bounded region is then the integral of 5x - 3x² from x = 0 to x = (5-m)/3

Area under y = 5x - 3x2 and y = mx is (125/54)/2 = 125/108

==> [0 to (5 -m)/3] ∫(5x - 3x²-mx )dx = 125/108

==> [0 to (5 -m)/3]∫( (5 - m)x - 3x2 )dx = 125/108

==> [0 to (5 -m)/3] ((5 - m)x²/2 - x³ )= 125/108

==> (5 - m)[(5 -m)/3]²/2 - ((5 -m)/3)³ = 125/108

==> (5 -m)³/18 - (5 -m)³/27 = 125/108

==> (5 -m)³/54 = 125/108

==> (5 -m)³ = 125/2

==> (5 -m) = 3.9685

==> m = 5 - 3.9685

==> m = 1.0315

Hence slope of line = 1.0315

A cooler contains 4.5 gallons of water and is filling up at a rate of 0.1 gallons per second. A second cooler contains 7 gallons
denpristay [2]

The equation that can be used to determine when each cooler would contain the same amount of water is 4.5 + 0.1t = 7 + 0.25t

<h3>When the coolers would have the same amount of water?</h3>

Equation that can be used to determine the amount of water in the first cooler at time t : 4.5 + 0.1t

Equation that can be used to determine the amount of water in the second cooler at time t : 7 + 0.25t

Where t represents seconds

When they have the same amount of water, the two above equations would be equal

4.5 + 0.1t = 7 + 0.25t

Combine similar terms

7 - 4.5 = 0.1t - 0.25t

2.5 = 0.75t

Hence the equation that can be used to determine when each cooler would contain the same amount of water is 4.5 + 0.1t = 7 + 0.25t

Answer:

largest 4 digit number × largest 3 digit number

(10000-1)×(1000-1) = (a-b)(c-b)= ac-ab-bc+b^2

10000000-10000-1000+1 = 9989001
