Find the x and y intercept of y= -2(x-3)^2+4

Mathematics

Neko [114]4 years ago

Y intercept occurs when x = o  so it is  -2(0-3) + 4  =   -2

x intercepts:-

-2(x - 3)^2  + 4 = 0
 
(x - 3)^2  = -4/-2 = 2

x - 3 = +/- sqrt2

x = 3 + sqrt2 and 3- sqrt2

El Papa de blanca destino la tercera parte de su salario quincenal para comprar alimentos y la mitad para pagos diversos si le s
kherson [118]

Answer:

El papá de Blanca gasta $1,000 de su sueldo en alimentos.

Step-by-step explanation:

En primer lugar, se designa a la letra S como la cantidad total del salario de la persona.

Sabiendo que el papá de Blanca destina la tercera parte de su salario para comprar alimentos, y que la tercera parte de un número es la división de ese número entre tres, entonces se tiene la expresión:

Alimentos: A=\frac{S}{3} =\frac{1}{3} *S

Ahora sabes que el papá de Blanca destina la mitad de su salario en diversos gastos, y siendo la mitad de un número es la división de ese número entre dos, se obtiene la expresión:

Gastos: G=\frac{S}{2} =\frac{1}{2} S

El papá de Blanca gasta su salario en alimentos y en otros gastos y le sobran $ 500. Esto es expresado mediante:

Alimentos + Gastos + 500 = Salario

Entonces:

A + G + 500 = S

Sustituyendo A y G:

\frac{1}{3} S+\frac{1}{2} S+500=S

Resolviendo:

\frac{5}{6} S+500=S

500=S- \frac{5}{6} S

500= \frac{1}{6} S

\frac{500}{\frac{1}{6} } =S

3,000= S

Entonces el salario del papá de Blanca es de $ 3,000

Reemplazando este valor para el cálculo de su gasto en alimentos es:

A=\frac{1}{3} *S= \frac{1}{3}* 3,000

A= 1,000

<em><u>El papá de Blanca gasta $1,000 de su sueldo en alimentos.</u></em>

A rectangle has a length of 35 feet less than 4 times its width. If the area of the rectangle is 3924 square feet, find the leng
zimovet [89]

Answer:

width = 36

length = 109

Step-by-step explanation:

width: x

length: 4x - 35

x * (4x - 35) = 3924

4x^2 - 35x = 3924

4x^2 - 35x - 3924 = 0

(4x + 109)(x - 36) = 0

x = -109/4 or x = 36

Obviously we have to use x = 36 because you can't have a rectangle with negative lengths and widths lol.

width = 36

length = 4(36) - 35 = 144 - 35 = 109

Dina and Masha start cycling on a 20 km bike path at the same time. When Dina reaches the end of the path, Masha still has 4 km
Schach [20]

Answer: Masha needs 40 more minutes to complete the path.

Step-by-step explanation:

So if Dina is cycling speed is 10km per hour that means it will take Dina 2 hours to completed the the path.

Here;   \frac{10km}{1h} = \frac{20km}{x }  

           10x = 20

       x= 2  

But since Masha still have 4 more km to go  you will add 20 + 4 =24

\frac{10}{1} = \frac{24}{x}

10x= 24

x= 2.4
