Answer: 2/8; 3/6 and 3/5

Step-by-step explanation:

3/6 = 1/2 = 0.5

3/4= 0.75

2/8= 1/4 = 0.25

To arrange in the order of least to greatest= 2/8; 3/6 and 3/5

Write an exponential function in the form of y=ab^x passing through the points (0,6) and (2,96)

taurus [48]

Here you have an equation with two unknown constants, a and b, plus 2 sets of points through which the graph goes.

Second point: 96 = a(b)^2
First point: 6 = a(b)^0 Then a = 6.

With a = 6, we can now write: 96 = 6b^2. Then b^2 = 16, and b=4.

Then y =6(4)^x (answer)

Thanks to a new conservation program, a population with only 200 individuals at the beginning of the year is growing exponential

sukhopar [10]

Answer:

0.3 per year

Step-by-step explanation:

Number of newborn per year: 200*0.5 = 100

Number of death per year: 200*0.2= 40

So, the difference between birth and death = 100-40 = 60 (people)

and the growth rate during the year is: 60/200 = 0.3

Hope this answer will find you well.

1. Homer has an idea for a new donut shop. He wants to design the donut shop so that the rectangular

Tju [1.3M]

Solving a system of equations, it is found that since the quadratic equation has two positive roots, they can be the values of the length and the width, and the design is possible.

The perimeter of a rectangle of length l and width w is given by:

$P = 2(l + w)$

The area is:

$A = lw$

In this problem, perimeter of 63.5 m, hence:

$2l + 2w = 63.5$

$2l = 63.5 - 2w$

$l = 31.75 - w$

Area of 225 m², hence:

$lw = 225$

$(31.75 - w)(w) = 225$

$w^2 - 31.75w + 225 = 0$

Which is a quadratic equation with coefficients $a = 1, b = -31.75, c = 225$ .

Then:

$\Delta = b^2 - 4ac = (-31.75)^2 - 4(1)(225) = 108.0625$

$w_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{31.75 + \sqrt{108.0625}}{2} = 21.1$

$w_2 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{31.75 - \sqrt{108.0625}}{2} = 10.68$

Since the quadratic equation has two positive roots, they can be the values of the length and the width, and the design is possible.

If f(x) = 3x2 and g(x) = x+2, find (f•g)(x).

Alecsey [184]

Since you have provided me with • symbol I must assume it's about function multiplication, but since standard keyboard doesn't have the function composition symbol $\circ$ I must assume you meant either.

1. Case you meant multiplication.

$(f\cdot g)(x)=3x^2\cdot(x+2)=\boxed{3x^3+6x^2}$

2. Case you meant composition.

$(f\circ g)(x)=f(g(x))=f(x+2)=3(x+2)^2=\boxed{3x^2+12x+12}$

Hope this helps. Next time please use LaTeX to format your equations so that others can give you answers as well.
