4 goes into 26 6 times with a remainder of 2.
26 ÷ 4 = 6 2/4
6 2/4 = 6 1/2
Your answer is 6 1/2
Give the number a label. That can be anything you want. A lot of people will use 'x' every single time they do a math problem,but there's no reason to do that and it's boring. Let's call our number ' M ' for 'Mystery number'. OK ?
The number . . . M
The square of the number . . . M²
Two more than the square of the number . . . M² + 2
You said that this is equal to 123, so we can write <u> M² + 2 = 123</u>
That's the equation we have to take and solve for ' M '.
Subtract 2 from each side of the equation, and you have M² = 121 .
Take the square root of each side: M = √121 .
The Mystery number is the square root of 121.
If you don't happen to know what that is, then you can use your pocket
calculator, or the calculator that comes with your computer (if you know
how to find it). They will all tell you that the square root of 121 is <em>11</em> .
That's a fine and wonderful answer, but technically, it's only half of the
answer. Any equation that has something squared in it almost always
has two solutions, and this one does.
The square root of 121 is a number that gives you 121 when you
multiply it by itself. ' 11 ' does that: (11 x 11) = 121 . Is there <em><u>another</u></em>
number that does the same thing ?
How about ' -11 ' ? Look at this: ( -11 x -11 ) = 121 . (Remember that
if both numbers being multiplied have the <em>same sign</em>, then their product
is positive.)
The bottom line is: The mystery number is<em> +11</em> and also<em> -11</em> .
Either one does what you want . . . When you square it and then
add 2 more, you get 123 either way.
The value of sin(30°) is 1/2.
<h3>What is Trigonometry?</h3>
The branch of mathematics concerned with specific functions of angles and their application to calculations.
The diagram is attached below:
We know,
sin 30= Perpendicular/ Hypotenuse.
As, the hypotenuse is the opposite side of the right angle and the perpendicular is opposite to the given angle.
So,
sin 30 = 5/10
sin 30 = 1/2

Answer:
A. 1)5.5 2)4.5 3)5.75 4)6.25 B. 1.75 C. A correct B incorrect C incorrect D correct
Step-by-step explanation:
Mean is a fancy way of saying <em><u>Average </u></em>, when calculating average you add all the numbers and divide by how many numbers there are:
<em><u>A</u></em>
<u>1.</u>
8+6+3+5=22/4=5.5
<u>2.</u>
5+7+4+2=18/4=4.5
<u>3.</u>
8+7+5+3=23/4=5.75
<u>4.</u>
6+8+4+5=25/4=6.25
<em><u>B</u></em>
largest mean is 6.25, smallest mean is 4.5:
<u>Subtract lowest mean from highest mean:</u>
6.25-4.5=1.75
<em><u>C</u></em>
<u>A)</u>
this is correct because averaging your average gives an overall average,
<u>B)</u>
if a is correct b has to be incorrect
<u>C)</u>
if D is correct C must be incorrect
<u>D)</u>
The closer they are together, that means more likely to be accurate because they are almost the same
I hope this helps u!
pls pls PLS give a brainliest and a thx ;)
To find a rational function's vertical asymyptotes, you need to find when the denominator is zero. So when is the denominator x² + 3x - 4 zero? We set that denominator equal to zero.
x² + 3x - 4 = 0
This second degree equation factors. We want a pair of numbers that multiply to 4, and there are only two pairs: 2 and 2, 1 and 4. We want the sum to 3, and one must be negative. -2 and 2 add to zero, -4 and 1 add to -3, -1 and 4 add to 3. The last one is the pair.
x² + 3x - 4 = 0
(x + 4) (x - 1) = 0
x = -4 or x = 1
So the function's vertical asymptotes are at x = 1 and x = -4.
