¿cualquier numero entero es un numero real ?​
mote1985 [20]

Answer:

Los números enteros son los naturales, sus opuestos (negativos) y el cero. El conjunto de los números enteros se representa mediante una Z, Z= {0,1,-1,2,-2,3,-3,4,-4...}. Se cumple entonces que todo número natural es entero.

A scientist is growing bacteria in a lab for study. One particular type of bacteria grows at a rate of y=2t^2+3t+500. A differen
Leya [2.2K]

ANSWER

Approximately after 15 minutes.

EXPLANATION

The growth rate of the first bacteria is

y = 2 {t}^{2}   + 3t + 500

The growth rate of the first bacteria :

y = 3 {t}^{2}  + t + 300

To find the time that, there will be an equal number of bacteria, we equate the two equation;

3 {t}^{2}  + t + 300 = 2 {t}^{2}   + 3t + 500

3 {t}^{2}  - 2 {t}^{2}   + t  - 3t +  300 - 500 =00

{t}^{2}  - 2t  - 200= 0

We solve for t to get,

t = 15.177

Or

t =  - 13.177

We discard the negative value.

This implies that,

t \approx15

How would you graph f(x) = 7x + 5 when you reflect it over y axis and translate it 3 units left
SOVA2 [1]

Answer:

See explanation

Step-by-step explanation:

Given the function f(x)=7x+5

1. To reflect the graph of the function f(x) over the y-axis, you should change the slope of the line in opposite. The slope of the function f(x) is 7, so the slope of the reflected function will be -7 and the expression of the reflected function will be

g(x)=-7x+5

2. To translate the function g(x) 3 units left, add 3 units to x, thus the expression for the function will be

h(x)=-7(x+3)+5\\ \\h(x)=-7x-21+5\\ \\h(x)=-7x-16

See attached diagram for details.
