Fatima plotted one side of a heptagon on a grid. the points (-8,1) and (-8,8) are joined to form a side of the heptagon. Fatima

Reil [10]

The general formula for the distance between two points is

$d(A,B) = \sqrt{(A_x-B_x)^2 + (A_y-B_y)^2}$

Anyway, if A and B have the same x or y coordinates, this formula can be simplified. For example, in this case the two points have the same x coordinate of -8, so the following part of the formula simplifies:

$(A_x-B_x)^2 = (-8-(-8))^2 = (-8+8)^2 = 0^2 = 0$

So, we're left with

$d(A,B) = \sqrt{(A_y-B_y)^2}$

but the square root of a square is the absolute value of the object being squared:

$d(A,B) = \sqrt{(A_y-B_y)^2} = |A_y-B_y|$

which is this case means $|1-8| = |-7| = 7$

which is the correct length of the side.

A. the series is absolutely convergent.

Dovator [93]

$\displaystyle\sum_{n=1}^\infty\left(1+\frac5n\right)^n$

Notice that

$\displaystyle\lim_{n\to\infty}\left(1+\frac5n\right)^n=e^5\neq0$

which means the series is divergent. So if this is one of those "select all that apply" questions, then both (c) and (j) are the only choices that do.

Which shows the correct substitution of the values a, b, and c from the equation 0 = – 3x2 – 2x + 6 into the quadratic formula?

ZanzabumX [31]

Answer:

shows correct substitution of the values a, b, and c from the given quadratic equation into quadratic formula.

Step-by-step explanation:

Given: The quadratic equation

We have to show the correct substitution of the values a, b, and c from the given quadratic equation into quadratic formula.

The standard form of quadratic equation is then the solution of quadratic equation using quadratic formula is given as

Consider the given quadratic equation

Comparing with general quadratic equation, we have
