Therefore , the solution to the given problem of quadratic equation comes out to be real.
An explanation of a quadratic equation.The quadratic equation x ax2+bx+c=0 is a non - linear regression model in a single variable. a 0. According to the First Theorem of Algebra, this polynomial has at least single solution because it is of second order. There could be simple or complex solutions. A four-variable equation is referred to as a quadratic equation. This implies that it must have at least one squared word. A typical formula for resolving quadratic formula is "ax2 + bx + c = 0," where the numerical factors or constant a, b, and c stand in for the undefined variable "X."
Here,
The graph is shown.
For this graph, we must discover the inequality.
The parent role is:
f(x) = x²
When we move the parent function back three units, we get,
f(x) = x² - 3
It is evident from this that option B is incorrect.
Check the additional disparities we obtain now.
Using the 1 and 3 choices we receive, choose any location from the shaded area.
x=-2 and y=0 are entered one by one into the inequality to yield,
FIRST CHOICE
y >= x²-3
0 >= (-2)²-3
0 >= 4-3
0>= 1
That is untrue.
3rd option
y<= x² - 3
0<= (-2)² -3
0<=1
This is real.
Choice 3 is the right one, thus.
Therefore , the solution to the given problem of quadratic equation comes out to be real.

Answer:
(1)
Step-by-step explanation:
We will try:
(1) y = [tex]\frac{1}{4}[/tex]x => 2 = 2 (seems legit)
(2) y = 4x => 2 = 32 (nope)
(3) y = x - 6 => 2 = 2 (yes but actually no because it is proportional relationship)
(4) y = [tex]\frac{1}{2}[/tex]x - 2 => 2 = 2 (like the above)
Round 30.425 to the nearest tenth.
Answers
Answer:
30.4
Step-by-step explanation:
30.425 rounded to the nearest tenth will be 30.4
When rounding to the nearest tenth, we have to see if the hundredths place and thousands place are 0.050 or greater.
If they are, then the tenths place will round up.
In this case, it is only 0.025, so we will keep the tenths place of 30.4
So, the answer is 30.4

un terreno de forma triangular tiene 250 pies de base por 180 pies de altura Cuál es la magnitud de su área en metro
Answers
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Areas..
Bienvenidos al concepto de áreas.
Área de un triángulo = 1/2 * base * altura,
aquí, base = 250, altura = 180, así que obtenemos como
Área = 1/2 * 250 * 180
Área = 250 * 90
Área = 22,500 mtrs.
The magnitude of the area of the triangular piece of land is approximately 2,094.2 square meters.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
First, let's calculate the area of the triangular piece of land in square feet:
Area = (1/2) x base x height
Area = (1/2) x 250 ft x 180 ft
Area = 22,500 sq. ft
To convert this to square meters, we can use the conversion factor of 1 sq. ft = 0.092903 sq. m:
Area = 22,500 sq. ft x 0.092903 sq. m/sq. ft
Area ≈ 2,094.2 sq. m
Rounding to the nearest tenth of a square meter, we get:
Area ≈ 2,094.2 sq. m
Therefore,
The magnitude of the area of the triangular piece of land is approximately 2,094.2 square meters.

Dagny Taggart has just purchased a home and taken out a $300,000 mortgage. The mortgage has a 25 year term with monthly payments and has an APR of 6% (monthly compounding). The total amount of interest that Dagny will pay during the first month of her mortgage is closest to:
a.
1923.24
b.
1816.93
c.
1500
d.
1485
Answers
Answer:
c.
1500
Step-by-step explanation:
The computation of the total amount of interest in first month is shown below:
Interest for first month is
= Mortgage amount × interest rate ÷ total number of months in a year
= $300,000 × 6% ÷ 12
= $1,500
Hence, the interest in the first month is $1,500
Therefore the c option is correct

Answer:
x = √2
Step-by-step explanation:
Perhaps you've heard of the Pythagorean theorem. It tells you the relationship between the sides (a, b) of a right triangle and the hypotenuse (c) is ...
c² = a² + b²
The diagonal of the square (diameter) is the hypotenuse of a right triangle with legs that are the sides of the square. Using the above relation, we have ...
x² = 1² + 1²
x² = 2
x = √2 . . . . . . the length of the diagonal (diameter)

Additional comment
The "take-away" from this is that an isosceles right triangle (one of the two "special" triangles) has side ratios of ...
side : side : hypotenuse = 1 : 1 : √2
