The required point of intersection of the two lines is (-2, 7/3).

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

The equation "y = 2/3x + 3" represents a line in the coordinate plane. It has a slope of 2/3 and a y-intercept 3. The equation "x = -2" represents a vertical line. It has no slope and the x-coordinate of all its points is -2.

Since the two equations represent lines, we can find their point of intersection by setting the two equations equal to each other and solving for y.

So, we have:

2/3x + 3 = y

and

x = -2

Substituting x = -2 into the first equation, we get:

2/3(-2) + 3 = y

Solving for y:

y = -2/3 * -2 + 3 = 4/3 + 3 = 7/3

Thus, the point of intersection of the two lines is (-2, 7/3).

The value of i is -56/a, Since the value of a is unknown, we cannot determine the exact value of i.

The area enclosed by the curve y = -x² and y = x² - i is the difference of the areas between these two curves.

To find the area enclosed by the curve y = x², we need to find its definite integral with respect to x from -∞ to ∞.

The definite integral of y = x² with respect to x from -∞ to ∞ is:

∫[-∞,∞] x² dx = (x³/3) from -∞ to ∞

Since the definite integral of an infinite function from -∞ to ∞ is undefined, we cannot find the exact value of the area enclosed by the curve y = x².

However, we can use the definite integral of y = x² - i with respect to x from -∞ to ∞ to find the area enclosed by the curve y = x² - i:

∫[-∞,∞] (x² - i) dx = (x³/3 - i * x) from -∞ to ∞

Again, the definite integral of an infinite function from -∞ to ∞ is undefined, so we cannot find the exact value of the area enclosed by the curve y = x² - i.

Since the area enclosed by the curve y = -x² is the same as the area enclosed by the curve y = x² but with the opposite sign, the difference of the areas enclosed by the two curves is equal to 56:

Area enclosed by y = x² - i - Area enclosed by y = -x² = 56

The first equation, y = -x^2, is a parabola that opens downwards.

The second equation, y = x^2 - i, is also a parabola but is translated downward by i units.

The area enclosed by the two curves will be the difference between the area under y = -x^2 and the area under y = x^2 - i.

The area under y = -x^2 can be calculated as follows:

A = ∫[-a,a] -x^2 dx = -(1/3) x^3 |^a_-a = (1/3) a^3

Where a is the x-value at which the two curves intersect.

The area under y = x^2 - i can be calculated as follows:

B = ∫[-a,a] (x^2 - i) dx = (1/3) x^3 - i x |^a_-a = (1/3) a^3 - i a

The area enclosed by the two curves is then given by:

C = B - A = (1/3) a^3 - i a - (1/3) a^3 = -i a

Since we know that the area enclosed by the curves is 56, we can set up the equation:

-i a = 56

So,

i = -56/a

Since a value is unknown, we cannot determine the exact value of i. However, we can use this equation to find the value of i for different values of a.

Therefore, The value of i is -56/a, Since the value of a is unknown, we cannot determine the exact value of i.

On the right side of the equation, x represents the exponent and log(x) represents the base.

This equation states that the logarithm of x raised to the power of x is equal to x times the logarithm of x.

Now let's simplify the other options:

x * log(x) is already simplified from the equation above, so we don't need to change it.

log(x) * log(x) is simply the logarithm of x raised to the power of 2, which is not equal to the logarithm of x raised to the power of x.

For 10 years, the value of the bond will be

b=1,000+200=1,200 dollars.

The value of the stock will be s=980⋅(1.02)10≈1,195 dollars.

They should choose the bond option if the period of investment is 10 years.

For 20 years, the value of the bond will be

b=1000+400=1,400 dollars.

The value of the stock will be 980⋅(1.02)20=1,456980⋅(1.02)20=1,456 dollars.

So they choose the stock option, if the period of investment is 20 years.
