The discriminant of the quadratic equation ax² + bx + c = 0 is b² - 4ac.
The equation is √ 2x² − 5x+ √ 2 = 0
So the value of a, b, c are 2, -5, √2 respectively
Therefore, the discriminant is (-5)² - 4(2)(√2) = 25 - 8√2
So, The discriminant for √ 2x² − 5x+ √ 2 = 0 is -8√2
Answer:
The discriminant of a quadratic equation ax² + bx + c = 0 is given by the formula:
b² - 4ac
Given the equation √ 2x² − 5x + √ 2 = 0, we can find the discriminant by substituting the values of a, b, and c into the formula:
b² - 4ac = (-5)² - 4(√2)(√2) = 25 - 8 = 17
So, the discriminant of the equation √ 2x² − 5x + √ 2 = 0 is 17

A teacher purchased 20 calculators and 10 measuring tapes for her class and paid $495. Later, she realized that she didn't order enough supplies. She placed another order of 8 of the same calculators and 1 more of the same measure tape and paid $178.50.
The system represents the situation
`20c+10m=495`
`8c+1m=178.50`
Find the cost of one calculator and the cost of one measure tape using one of our methods of solving systems.
Answer:
Equations are
20c + 10m = 495..............(1)
8c + 1m = 178.5.................(2)
Now , equation (2) * 10 = 80c + 10m = 1785...........(3)
So, Eq. (3) - Eq(1) =
80c + 10m - 20c - 10m = 1785 - 495
60c = 1290
c= 21.5
********************************************************
Now place the value of c in Eq (2)
So , m =6.5

Mrs. Beppu's property has four sides. An aerial view of her property is shown below. What term best describes the shape of her property?
Answer:
rectangle
Step-by-step explanation:
From the picture attached below of the aerial view of Mrs. Beppu's house we can see that it is a rectangle. That is because it has 4 sides with only the parallels being the same size. Meaning that both the width and the length of the house are not the same. This removes the possibility of it being a square. Since all the angles seem to be right angles it also removes the possibility of it being a trapezoid. The best choice would be that it is a rectangle.

Answer:
9.219544
Step-by-step explanation:
(8 - -1)^2 + (0 - -2)^2 = 85, sqrt 85 = 9.219544
Answer:
Step-by-step explanation:
Distance formula : d=√((x_2-x_1)²+(y_2-y_1)²)
d=√((8-(-1))²+(0-(-2))²)
d=√((9)²+(2)²)
d=√(81+4)
d=√(85)
d = 9.21954445729
Find the value of k, represented as a decimal rounded to the nearest tenth.
5/7 = 12/k
Answer:
We conclude that the value of k represented as a decimal rounded to the nearest tenth is: [tex]k = 16.8[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{5}{7}=\frac{12}{k}[/tex]
We need to determine the value of k, represented as a decimal rounded to the nearest tenth.
Let us solve the expression
[tex]\frac{5}{7}=\frac{12}{k}[/tex]
Apply cross-function multiply: if [tex]\frac{a}{b}=\frac{c}{d}[/tex] then [tex]a\cdot \:d=b\cdot \:c[/tex]
[tex]5k=7\cdot \:12[/tex]
[tex]5k=84[/tex] ∵ 7 · 12= 84
Divide both sides by 5
[tex]\frac{5k}{5}=\frac{84}{5}[/tex]
Simplify
[tex]k=\frac{84}{5}[/tex]
[tex]k = 16.8[/tex] (Rounded to the nearest 0.1 or the Tenths Place)
Therefore, we conclude that the value of k represented as a decimal rounded to the nearest tenth is: [tex]k = 16.8[/tex]

Lanie's room is in the shape of a parallelogram. The floor of her room is shown below and has an area of 108 square feet. Lanie has a rectangular rug that is 6 feet wide and 10 feet long. Will the rug fit on the floor of her room? Use the drop‐down menus to explain and show your answer.
Answer:
Yes it would
Step-by-step explanation:
Lanie's room is in the shape of a parallelogram.
Lanie has a rectangular rug that is 6 feet wide and 10 feet long.
Area of a rectangle = Length × Width
Area of the rectangular rug = 10 feet × 6 feet
= 60 square feet
We are told that:
The floor of her room is shown below and has an area of 108 square feet.
Hence, the rug would fit on the floor of her room because it's area is within the area of the floor of her room.

Dentro de cinco años mi abuelo tendrá el cuádruple de mi edad. Hace cinco años tenia siete veces mi edad¿que edad tenemos el y yo?
Answer:
La edad del abuelo es 75 años y la tuya es de 15 años.
Step-by-step explanation:
Si dentro de 5 años tu abuelo (A) tendrá el cuádruple de tu edad (E), tenemos:
[tex] A + 5 = 4(E + 5) [/tex] (1)
Ahora, si hace cinco años tenia siete veces tu edad:
[tex] A - 5 = 7(E - 5) [/tex] (2)
Multiplicando la ecuacion (1) por -1, tenemos:
[tex] -A - 5 = -4(E + 5) [/tex] (3)
Ahora sumando la ecuación (3) con (2):
[tex] -10 = 3E - 55 [/tex]
[tex] E = 15 [/tex]
Entonces, reemplazando el valor de E en la ecuación (1):
[tex] A + 5 = 4(15 + 5) [/tex]
[tex] A = 75 [/tex]
Por lo tanto, la edad del abuelo es 75 años y la tuya es de 15 años.

Tan(x) *cos(x)*cos(x)= ( the answer should have sin only ) ASAP
This doesn't make any sense because you didn't give a value to cos like you did to sin.
Let me guess the actual question is tan(x)*cos(x) write this in term of sin.
Now from trigonometry identities, we know that tan(x)=sin(x)/cos(x)
So the expression can be written as sin(x)/cos(x)*cos(x)
which results in sin(x) as the answer, if I guessed the question wrong, sorry and please tell me in the comments what the correct question is, because this question doesn't seem complete :)

At the market you can buy 6 bags of apples for $25. At the orchard you can get 8 bags of apples for $35. Which is the better deal?
Answer:
6 bags for $25
Step-by-step explanation:
25/6 = 4.16666666667 = $4.17 per bag
35/8 = 4.375 = $4.37 per bag
The better deal for the bags of apples is at the market
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
To determine which is the better deal, we can compare the prices per bag of apples at the market and the orchard.
At the market:
Price of 6 bags of apples = $25
Price per bag of apples = $25 / 6 ≈ $4.17 (rounded to two decimal places)
At the orchard:
Price of 8 bags of apples = $35
Price per bag of apples = $35 / 8 ≈ $4.38 (rounded to two decimal places)
Comparing the two prices per bag of apples, we can see that the price per bag at the market is $4.17, while the price per bag at the orchard is $4.38.
Hence , the better deal is at the market where you can buy 6 bags of apples for $25, resulting in a lower price per bag compared to the orchard.
