Line m passes through points (6, 8) and (2, 1). Line n passes through points (9, 10) and (2, 6). Are line m and line n parallel or perpendicular?

The value of the angle m∠ KJL  in the triangle is 68 degrees.

The angle m∠ KJL can be found using triangle exterior angle theorem. The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

Therefore, the angle can be found as follows:

∠JLM = 141 degrees

∠JKL = 73 degrees

Hence,

∠JLM = ∠ KJL + ∠JKL

∠ KJL = 141 - 73

∠ KJL = 68 degrees

Height (h) is the dependent variable and minutes (m) is the independent variable in the equation h=60-4m.

In algebra, a symbol (usually a letter) used to indicate an unknown numerical value in an equation or algebraic statement. A variable is a quantity that is changeable rather than fixed. In mathematics, a variable is an alphabet or phrase that represents an unknown amount, unknown value, or unknown number. Variables are very useful in algebraic expressions or algebra. As an example, the variables x and 9 are constants in the linear equation x+9=4.

Here,

m- minutes is the independent variable

The equation of the vertical line passing through (-5,-2) is x = -5.

In the given question, we have to find the equation of the vertical line through (−5, −2).

The given point is (−5, −2).

Vertical Line is a line that runs perpendicular to the Y-axis. It runs in a straight line from top to bottom and vice versa.

We are aware that the y-axis' slope is unknown.

Therefore, any vertical line is perpendicular to the y-axis and has an arbitrary slope.

The vertical line equation is given as x = k, where k can take on any value along the x-axis.

We must enter x = -5 because the line passes through the point (-5, -2).

So, x = k = -5

Hence, the equation of the vertical line passing through (-5,-2) is x = -5.

So, the answer is $285,671.10 (Option b) that must be deposited earning 6.2% compounded yearly in order to make the annuity payment of $25,312 for 20 years.

The formula to determine the future value of an annuity is given by

FV = PV(1+r)^n + PMT( (1+r)^n - 1) / r

Where:

FV is the future value of the annuity

PV is the present value of the annuity

PMT is the payment made at the end of each period

r is the interest rate per period

n is the number of periods

We know that the payment made at the end of each period (PMT) is $25,312, the interest rate (r) is 6.2% and the number of periods (n) is 20.

We are looking for the present value of the annuity (PV)

So we can substitute the known values into the formula and solve for PV:

PV = PMT( (1+r)^n - 1) / (r (1+r)^n)

PV = $25,312 * ( (1+0.062)^20 - 1) / (0.062 (1+0.062)^20)

PV = $25,312 * (1.062^20 - 1) / (0.062 * 1.062^20)

PV = $25,312 * (1.062^20 - 1) / (0.062 * 1.062^20)

PV = $25,312 * (2.547 - 1) / (0.062 * 2.547)

PV = $25,312 * 1.547 / 0.157

PV = $285,671.10
