Lyla buys a fish tank that has the dimensions b by b? by 4 What is the volume of her new fish tank?
Valentin [98]

Since calculating volume is multiplying the side lengths together we first have:

b x b x 4

Then we can simplify b x b to b ²

And when you multiply b² by 4 you get 4b²

Answer: 4b² is the volume of the fish tank.

Use graphing technology to find the range of the function f(x)=x2 +6x+9
lbvjy [14]

Answer:

See below.

Step-by-step explanation:

Refer to the graph.

The range of a graph is the span of y-values it covers.

From the graph, we can see that the span of y-values is all values greater than or equal to 0.

Therefore, our range is, in interval notation:

[0,\infty)

Note that we use brackets with the 0 because 0 is included in our range.

In set notation, this is:

\{y|y\in\mathbb{R},y\geq 0\}

Very large or very small numbers are best input with exponential notation. For instance, the number 8,000,000 (eight million) is
Lerok [7]

Answer:

9*10^{12}km

Step-by-step explanation:

9,460,730,472,580.8 km

First, we can work out 5% of our number, by multiplying it by 0.05

9,460,730,472,580.8 * 0.05 = 473,036,523,629

Now, if we add and subtract our 5% calculated from our original number, we can work out the minimum and maximum value that our final answer can be in the range of.

9,460,730,472,580.8 + 473,036,523,629 = 9.933767*10^{12}\\9,460,730,472,580.8 - 473,036,523,629 =8.98769395*10^{12}

We can see that 9*10^{12} is in the range of valid answers, as:

8.9*10^{12} \leq 9*10^{12} \leq 9.9 * 10^{12}

So, our final answer is:

9*10^{12}km
