Given the Arithmetic sequence A1,A2,A3,A4 28, 33, 38, 43 What is the value of A11?

harkovskaia [24]

28,33,38,43

the common difference can be found by subtracting the first term from the second term.....33 - 28 = 5....so the common difference (d) = 5

an = a1 + (n - 1) * d
n = the term u want to find = 11
a1 = first term = 28
d = common difference = 5
now we sub
a11 = 28 + (11 - 1) * 5
a11 = 28 + 10 * 5
a11 = 28 + 50
a11 = 78

Answer:

1). $(x+\frac{1}{4})^{2}=\frac{4}{9}$

2). $x+\frac{1}{4}=\pm \frac{2}{3}$

Step-by-step explanation:

Here the given equation is $x^{2}+\frac{1}{2}x+\frac{1}{16}=\frac{4}{9}$

We have to factor the perfect square trinomial on the left side of the equation

So left side of the equation is $x^{2}+\frac{1}{2}x+\frac{1}{16}$

= $x^{2}+2\times \frac{1}{4}x+(\frac{1}{4})^{2}$

$=(x+\frac{1}{4})^{2}$ since [(a+b)²= a²+b²+2ab]

Therefore the factorial form of the equation will be

$(x+\frac{1}{4})^{2}=\frac{4}{9}$

Now we have to solve the equation by applying square root property

$\sqrt{(x+\frac{1}{4})^{2}}=\sqrt{\frac{4}{9}}$

$x+\frac{1}{4}=\pm \frac{2}{3}$

The distance between two points is the number of units between them.

<u>Halfway points (a) and (b)</u>

To locate a point halfway points (a) and (b), we use the following steps

Calculate the absolute difference between both points
Divide the absolute difference by 2
Add the quotient to the smaller point.

Assume the smaller value is (a), the point (P) halfway points (a) and (b) would be

$P = a + \frac{|a - b|}{2}$

Take for instance, a = 5, and b = 10.

The halfway point would be:

$P = 5 + \frac{|5 - 10|}{2}$

$P = 5 + \frac{5}{2}$

$P = 5 + 2.5$

$P = 7.5$

The halfway point between 5 and 10 is 7.5

The formula works for negative values, and absolute values are used to return the actual difference between both points

<u>Real world circumstance</u>

The formula can be used to calculate the halfway distance between a school gate and the school library (as an instance)

<u>Fractional distance</u>

To determine the fractional distance, we simply replace the 1/2 in the original formula with the appropriate fraction.

Take for instance, three-fourths from (a) to (b) would be:

$P = a + \frac{3|a - b|}{4}$
