If h(x) = 2x^2 , then h(-2) + 5=_________

Mathematics
1 answer:
Vaselesa [24]4 years ago
8 0

Answer:

13

Step-by-step explanation:

Given the equation h(x) = 2x²

To solve for h(-2) + 5 then, we need to break the problem into two parts

First, we will solve for the function h(x) at x = -2

h(x) = 2x² so

h(-2) = 2(-2)²

h(-2) = 8

Knowing this, we can plug 8 into our original expression for h(-2)

8 + 5

This gives us 13

Ique si los puntos: A( -3 , 3 ) y B( 0 , -15 ), pertenecen o no a la recta -4x-y+15=0
Papessa [141]

Respuesta:

El punto A(-3, 3) pertenece a la recta.

El punto B(0, -15) no pertence a la recta.

Explicación paso a paso:

Consideremos la siguiente ecuación de la recta en forma estandar.

-4x - y + 15 = 0

Para verificar si los puntos A y B pertencen a la recta, primero la transformaremos a la forma explícita.

-4x - y + 15 = 0

-4x + 15 = y

y = -4x + 15

El punto A(-3, 3), tiene coordenada x -3 y coordenada y 3. Reemplazaremos x en la ecuación de la recta y veremos si obtenemos el mismo valor de y.

y = -4(-3) + 15 = 3

El punto A(-3, 3) pertenece a la recta.

El punto B(0, -15), tiene coordenada x 0 y coordenada y -15. Reemplazaremos x en la ecuación de la recta y veremos si obtenemos el mismo valor de y.

y = -4(0) + 15 = 15

El punto B(0, -15) no pertence a la recta.

An Olympic-sized swimming pool can hold approximately 6.60 x 105 gallons of water. Calculate the volume of the water in cubic me
shutvik [7]

The volume of the pool is 1.74*10^8 cubic meters

To solve this problem, we convert the volume of the water from gallons to m^3.

<h3 /><h3>Conversion of Unit</h3>

This is done to convert one unit of a substance to another unit of that particular substance. In this question, we are converting from gallon - meter cube

Data;

  • v = 6.60*10^5
  • 1 gallon = 264.17m^3

let's solve for v

1gallon  = 264.17m^3\\&#10;6.60*10^5 gallon = x

cross multiply both sides and solve for the volume in cubic meters

x = 6.60*10^5 * 264.17\\&#10;x = 174352200\\&#10;x = 174.352*10^6m^3 = 1.74*10^8m^3

The volume of the pool is 1.74*10^8 cubic meters
