Answ $1*10^{9} \\$

Step-by-step explanation:

Movemos la coma de los decimales de forma que 1000000000,0 se convierta en un nuevo número entre el 1 y el 10. Como nuestro número es mayor que 10, movemos la coma hacia la izquierda. Quita los ceros del final. Lleva la cuenta de cuántas veces movemos la coma decimal.

1000000000,0 -> 1

Nuestro nuevo número es 1. Hemos movido la coma decimal 9 veces.

Como nuestro número original era mayor que 10, el exponente de 10 es positivo. Recuerda que movimos la coma decimal 9 veces, de forma que el exponente es 9 positivo:

$10^{9}$

What is the range in interval notation of the function graphed below?

attashe74 [19]

Answer:

Range tells you how high and low the graph of this parabola goes in the “y” (vertical) directions.

1. We can see that the parabola peaks on the y-axis at y = 4. That’s as HIGH as it goes.

2. We also see that both sides of the parabola descend to the level of y = -7. That’s as LOW as it is shown to go.

So putting these together, we say the Range is given by:

-7 <= y <= 3

AMBIGUITY WARNING:

Because the two branches of the parabola go fall right down to the edge of the picture boundary, it’s UNCLEAR whether the parabola truly stops at y = -7 or CONTINUES on (to negative infinity).

In THAT case, the RANGE simplifies to:

Y <= 4

Done.

X=29 and y=10

You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.
