a piece of wire 100 inches long is cut into two pieces and each bent into the shape of a square. if the sum of the areas of the two squares is 400 in2, find the length of each piece of wire.
The length of the pieces of wire include 23.5425 inches and 75.4565 inches.
How to calculate the length?Given the total length of wire is
X+Y=100
Y=100-X
Then we bend the two pieces into squares so that the sides of each square are X/4 and (100-X)/4. Therefore
(X/4)² + [(100-X)/4]² =400
X² +10000-200X +X² =6400
X²-100X+1800=0
Solving the equation
X = 76.4565 inches and X=23.5425 inches
Therefore, the length of the pieces of wire include 23.5425 inches and 75.4565 inches.

√2x-1+3=4
Answer:
x = 2
Step-by-step explanation:
Let's solve for the value of x,
→ √2x - 1 + 3 = 4
→ √2x + 2 = 4
→ √2x = 4 - 2
→ 2x = (2)²
→ x = 4/2
→ [ x = 2 ]

What is the difference of ‒6 ‒ 15?
Answer: -21
Step-by-step explanation:
To solve this, you must subtract either one of the numbers from the other, then take the absolute value.
The easiest way is to subtract -6 from 15, since it will allow you to work with positive numbers.
So you do 15 - (-6), which is the same as 15 + 6. The answer is -21, and since it is a positive number, no further calculations are required to find the absolute value.

if alpha and beta are the roots of the equation 4 x square - 5 x - 1 equals to 0 find the quadratic equation whose roots are two minus alpha coma to minus beta
Answer:
4x² -11x +5 = 0
Step-by-step explanation:
Given α and β are roots of 4x² -5x -1 = 0, you want to find the quadratic equation that has (2-α) and (2-β) as its roots.
Factored formFactoring out the leading coefficient, we can write the factored form of the given quadratic as ...
4(x -α)(x -β) = 0 = 4x² -5x -1
When the roots are changed from α and β to (2-α) and (2-β), the factored form of the new equation is ...
4(x -(2 -α))(x -(2 -β)) = 0
4(x -2 +α)(x -2 +β) = 0
Negating both factors allows us to write this in a familiar form:
4((2 -x) -α)((2 -x) -β) = 0
Comparing to the original factored quadratic, we see that this is the original with x replaced by (2 -x). Then the quadratic we seek is ...
4(2-x)² -5(2 -x) -1 = 0 . . . . . . . . . . . original with x replaced by (2-x)
4(4 -4x +x²) -10 +5x -1 = 0 . . . . simplify a bit

The quadratic whose roots are (2-α) and (2-β) is 4x² -11x +5 = 0.

Find the coordinates of the centroid of the triangle with the given vertices. (Lesson 5-2)
U(-5,5), K(-5,-1), L(1,2)
The triangle with vertices located at U(-5 , 5), K(-5 , -1), and L(1 , 2) has its centroid located at (-3 , 2).
The centroid of a triangle is the point inside the triangle where the three medians intersect. The median of a triangle is the line the connects the midpoint of a side and the opposite vertex.
To get the centroid of a triangle, use the formula given by:
C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]
where C is the centroid of the triangle located at (x , y)
x1, x2, and x3 are the x-coordinate of the vertices of the triangle
y1, y2, and y3 are the y-coordinate of the vertices of the triangle
Let Point 1(x1 , y1) = U(-5 , 5)
Point 2(x2 , y2) = K(-5 , -1)
Point 3(x3 , y3) = L(1 , 2)
Plug in the values in the formula.
C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]
C(x ,y) = [(-5 + -5 + 1)/3 , (5 + -1 + 2)/3]

The correct option is (C) 45°
The measure of angle ∠OCA = 45°.
What is the tangent?A circle is a depiction with no sides or vertices.
It includes a radius as well as a center. The center is the point from which all other points just on circle are equidistant, and the distance between them equals the radius.
Let AC equal the tangent to the circle with center O.
OA ⊥ AC ....(The tangent has always been perpendicular to the radius.)
As, it is given that ∠OAC = 90° and ΔOAC is isosceles triangle.
Thus, ∠O = ∠C = x (say)
Now, using the triangle's angle sum property. We have it,
90° + x + x= 180°

graph the equation y= 2/3x+5
the equation formula y=2/3x+5 is (3,-3).
In mathematics, what is an equation?Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
based on the available facts;
You might be wondering how, but we can start with that 5 at the end, which denotes the y-intercept.
If 0 is used in place of x, then y=2/30+5y=5
We shall receive the first coordinate as a result, which is (0,5).
Let's then consider the slope, which is 2,3. As you may already be aware, the slope is also known as
rise/run
; what do they mean by that is that the first top number tells you how many units you go up and the second one how many units you go right or how many units you go down and go left.
Now, I know this may seem complicated but let's make it clear. Since we know one coordinate, which is
(0,5)
, from that point by knowing the slope we can find a second point; this point is 2 points above and 3 to the right, which tells us that −5+2
points above gives us −3 and 3 points on the right gives us a new coordinate:
(3,−3)
And since we now know two coordinates, that is enough to draw the line and have the graph.

An inequality that represents Alicia’s possible age is x < 8.
For given question,
let x represent Alicia's age.
Amy is eight years older than twice her cousin Alicia’s age.
So, Amy's age would be 2x + 8
The sum of their ages is less than 32.
We write above statement in mathematical expression.
sum of their ages = (2x + 8) + x
= 3x + 8
The sum of their ages is less than 32.
We use the symbol < for 'less than'
So, the mathematical expression form of given statement would be,
(3x + 8) < 32
So, we get an inequality 3x + 8 < 32
⇒ 3x < 32 - 8
⇒ 3x < 24

1 x 10 + 2 x 35 = 80
=> 80 ÷ 3 = 26.66
1x10 + 1x35 = 45

1 x 10 + 0.5 x 35 = 27.5
=>27.5 ÷ 1.5 = 18.33
1 x 10 + 0.4 x 35 = 24
=>24 ÷ 1.4 = 17.14
1 x 10 + 0.2 x 35 =17

Hence, the equation of exponential function is represented by y = A(Bˣ)
An exponential function is a mathematical function of the form f(x) = ax, where "x" is a variable and "a" is a constant called the base of the function and it must be greater than 0. The most commonly used exponential basis is the transcendental number e, which is approximately equal to 2.71828The equation in exponential form
y = A(Bˣ)
Case 1 :
x =0 y = 0.02
0.02 = A (B⁰)
A = 0.02
Case 2:
x = 1 y =0.04
0.04 = 0.02(B)
0.04 /0.02 = B
B = 2
Case 3 :
x = 2 y =0.08
0.08 = 0.02(2²)
0.08 = 0.08
Case 4 :
x = 3 y = 0.16
0.16 = 0.02(2³)
0.16 = 0.16
