Step-by-step explanation:

The discriminant of a quadratic equation is expressed using the equation:

D = b²-4ac. It talks about the nature of the roots of a quadratic equation.

If D>0, then the roots is real and unequal/distinct

If D<0 the roots are unreal and imaginary

If D = 0, the  roots are real and equal (one real root)

According to this question, since the root given is a real value and also one value, then the the roots are real, rational and equal. Note that the root is rational since we can write it as a ratio of two integers e.g 34 = 34/1. 34 and 1 are integers

Answer:

FV= $4,117.1

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $3,500

Number of periods= 5*12= 60 months

Interest rate (i)= 0.0325/12= 0.00271

To calculate the Future Value, we need to use the following formula:

FV=PV*(1+i)^n

FV= 3,500*1.00271^60

FV= $4,117.1

Answer:

A. 2/3w

Step-by-step explanation:

Option A is correct, g = 2/3 w is a direct variation equation for the given relationship

To determine the direct variation equation, we need to check if the ratio of green cans (g) to white cans (w) is constant across all the given ratios.

Let's calculate the ratios for each case:

For the first ratio: g = 6 and w = 9

g/w = 6/9

= 2/3

For the second ratio: g = 10 and w = 15

g/w = 10/15

= 2/3

For the third ratio: g = 16 and w = 24

g/w = 16/24

= 2/3

For the fourth ratio: g = 18 and w = 27

g/w = 18/27

= 2/3

Since the ratio of g/w is the same (2/3) for all cases, we can see that the relationship between green cans (g) and white cans (w) is a direct variation

Hence,  the direct variation equation is g = 2/3 w, option A is correct.

Answer: 15

Step-by-step explanation:

Let's define the concept of inverse functions.

If we have a function h(x), such that it has an inverse, and:

h(x) = y.

Then the inverse function j(x) must meet the following:

j(y) = x.

Now, we want to calculate:

h( j(15) ).

Let's suppose that:

j(15) = A.

(Where A can be any real number).

then, by the above relation, we must have that:

h(A) = 15.

Now we can replace j(15) by A in h(j(15)):

h( j(15) ) = h( A ) = 15.

Step-by-step explanation:

One real root

The nature of the roots of [tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex] is (a) one real root

The equation is given as:

[tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex]

To determine the nature of the roots, we make use of determinants.

The determinant (d) of a quadratic equation is calculated

[tex]\mathbf{d = b^2 - 4ac}[/tex]

Where the quadratic equation is:

[tex]\mathbf{ax^2 + bx + c = 0}[/tex]

By comparison, we have:

[tex]\mathbf{a = 49,\ b = -28,\ c = 4}[/tex]

So, we have:

[tex]\mathbf{d = b^2 - 4ac}[/tex]

[tex]\mathbf{d = (-28)^2 - 4 \times 49 \times 4}[/tex]

[tex]\mathbf{d = 784 - 784}[/tex]

[tex]\mathbf{d = 0}[/tex]

When d = 0, then the function has one real root.

Hence, the nature of the roots of [tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex] is (a) one real root
