Answer:
25y^2 -20iy + 4i^2
Step-by-step explanation:
Theres an acronymn called Foil (first, ouside, inside, last) for expanding an expression like that
For this expression:
= (5y - 2i) (5y - 2i)
= 25y^2 - 10iy - 10iy + 4i^2
= 25y^2 -20iy + 4i^2
This is assuming that "i" is not the imaginary number "i"
Fiod the amountof tax and the tax rate. Round to nearest hundredth of a percent
Cost ofitem: $148
Selling price: $154.4
Tax amount: $
Tax rate: %
Answer:
Tax Amount: $6.40
Tax rate: 4.32%
Step-by-step explanation:
1. To get the tax amount, subtract the cost of the product from the selling price.
$154.40-$148.00 = $6.40
2. Divide the tax amount by the cost of the item.
6.40 ÷ 148=0.0432
3. Multiply by 100
0.0432 × 100 = 4.32%

Answer:
5 ft, 6.5 ft, 7 ft
Step-by-step explanation:
area of trapezoid = (base1 + base2)h/2
Let the unknown base = x
area of trapezoid = (8.5 + x)(6)/2
area = 3x + 25.5
We want the area to be between 40 ft^2 and 48 ft^2.
40 < 3x + 25.5 < 48
14.5 < 3x < 22.5
4.8333 < x < 7.5
Answer: 5 ft, 6.5 ft, 7 ft

Step-by-step explanation:
Malcolm has 225 yards of yarn to make 100 bracelets. Suppose the total length of the yarn stayed the same, but instead of Malcolm making 100 bracelets, he only made 1,000 bracelets. How long will the yarn be for each bracelet
Given :
Length of yarn, l = 225 yards.
Number of bracelets he made, n = 1000 .
To Find :
How long will the yarn be for each bracelet.
Solution :
Let, length of yarn used in each bracelet is x.
So,
[tex]x = \dfrac{Total\ length \ of yarn}{Number \ of \ bracelets\ made}\\\\x = \dfrac{225}{1000}\\\\x = 0.225 \ yards[/tex]
Therefore, length of yarn used in each bracelet is 0.225 yard.

) Tina planted 75 plants. N plants did not grow leaving her with 48 plants. Which equation expresses how many plants Tina lost?
Answer:
Step-by-step explanation: I think this is the answer
Tina planted 75 plants and only 48 grow
To know how much is lost we subtract 75 from 48 which gives us 27
75-48=27

Answer:
b = 12
Step-by-step explanation:
a² + b² = c²
a and b are the length of the sides in the right triangle and c is the hypotenuse.
since we know one leg and the hypotenuse, we can find the other leg.
9² + b² = 15²
81 + b² = 225
b² = 225 - 81
b² = 144
b = 12
Answer:
The answer is 12
Step-by-step explanation:
the formula is A^2+B^2=c^2
9² + b² = 15²
81 + b² = 225
b² = 225 - 81
b² = 144
b = 12

If a line goes through the following two points: (0,0) and (2,1), the slope of the line is:
A. 3
B. -2
C. 1/2
D. -1/2
Answer: m = 1/2
Step-by-step explanation: Let's use the graphing method.
To find the slope of the line using the graphing method,
we first set up a coordinate system.
Next, we plot our two points, (0, 0), which we label point A, and (2, 1),
which we label point B, and we graph our line, as shown below.
Now just graph the line through the two points.
Now, remember that the slope, or m, is equal to the
rise over run from point A to point B.
To get from point A to point B, we rise 1 unit and run 2 units.
So our slope, or rise over run, is 1/2.

Producción de vehículos. En en el año 2000 FIAT produjo 1,135 autos y en el año 2010, produjo 1,825 autos. Teniendo un crecimiento lineal cada año. Determina un modelo lineal (Ecuación General) de dicho comportamiento de producción de autos con los datos que se proporcionan.
Answer:
El modelo lineal del comportamiento de producción de autos es y=69*x -136865
Step-by-step explanation:
Una función real de variable real es una función lineal si es de la forma f(x)=mx+n o y=mx+n. Es decir, la ecuación de la función se corresponde con un polinomio de primer grado. La representación gráfica de una función lineal es siempre una recta. El coeficiente m recibe el nombre de pendiente de la recta y será el responsable de lo inclinada o “pendiente” que se encuentre la recta respecto del eje X mientras que b es el intercepto con el eje Y.
Teniendo dos puntos (x1,y1) y (x2,y2) se puede calcular la pendiente mediante la expresión:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Para encontrar el valor de b, una vez reemplazado el valor de m en la ecuación se sustituye los valores de x y de y por los valores de las coordenadas de uno de los puntos, sea el uno o el dos y se despeja b para así obtener su valor.
En este caso y representará la producción de autos mientras que x cada año de producción. Entonces se tiene los siguientes puntos: (2000; 1135) y (2010; 1825)
Por consiguiente, el valor de m será:
[tex]m=\frac{1825-1135}{2010-2000}[/tex]
m=69
Entonces: y=69*x + b. Eligiendo el punto (2000; 1135) y reemplazando:
1135= 69*2000 + b
Se obtiene que el valor de b es:
1135= 138000 + b
-136865= b
Entonces el modelo lineal del comportamiento de producción de autos es y=69*x -136865
which expression is equivalent to the given expression? 2x^2-14x+24
A.) 2(x-3)(x-4)
B.) 2(x-5)(x-2)
C.)(2x-12)(x-2)
D.)2(x-8)(x+3)
