Answer

+2 and -2

Explanation

x^2-4=0 Is a quadrilateral expression. we can solve it using complete square method.

x²-4=0

x² - 4 + 4 = 0 + 4

x² = 4

x = √4 or x = - √4

= +2 = -2

How do I write a rule for the nth term of the sequence?

crimeas [40]

first of all we have the 5th term and 2nd term

T5=768 =a*r^4

T2=-12=a*r ^1

make a subject of formula in the both equations

that is a=T2/r and T5/r^4

a=12/r and a=768/r^4

when u equate them u will get

-64=r^3 so r=-4 then to find a that is 1st term

since second term is T2=a*r=12 an r=-4 then

a=12/-4 hence a=-3

What is the following logarithmic equation in exponential form: log2(x^4 -3) = 4

Harman [31]

Answer:

$2^{4}$ = $x^{4}$ - 3

Step-by-step explanation:

recall for a logrithimic expression,

$log_{b}$ (c)=a, can be expressed as $b^{a} = c$

hence for our question

$log_{2}$ [ (x^4) -3] = 4

can be expressed as

$2^{4}$ = $x^{4}$ - 3

Three vertices of a rectangle are (6,1), (3,1), and (3,8). What are the coordinates of the fourth vertex?

jonny [76]

Answer:

Image result for Three vertices of a rectangle are (6,1), (3,1), and (3,8). What are the coordinates of the fourth vertex?

One would be to divide the rectangle into two triangles, then use the Pythagorean Theorem to find the distances between the points, and finally use Heron's formula to find the areas of the two triangles.

To find the area of a triangle where you know the x and y coordinates of the three vertices, you'll need to use the coordinate geometry formula: area = the absolute value of Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By) divided by 2.

George wrote an integer. The opposite of George’s integer is -53. Which of these statements about George’s integer must be true?

vlabodo [156]

The George's integer must be true for option D)I and IV.

What is integer?

A full number (not a fraction) that can be positive, negative, or zero is called an integer . -5, 1, 5, 8, 97, and 3, 043 are some examples of integers. 1.43, 1 3/4, 3.14, and other numbers are examples of non-integer numbers. Integer, which means full or whole in Latin, is the root of the English term integer. A particular category of numbers called integers includes zero, positive numbers, and negative numbers. All whole numbers, both negative and positive, and 0 are considered integers.

Here the opposite of George integer is -53.

We know that opposite value of x is -x.

Then George integer is 53.

George integer must be true for The given options I. the integer is 53 and IV.The integer has absolute value of 53.

Therefore the correct option is D) I and IV.
