Given:Length = 4,450.5 metersWidth = 2,890 meters
1 kilometer = 1,000 meters
Length: 4,450.5 meters * 1km/1,000 meters = 4,450.5 km/1,000 = 4.4505km
Width: 2,890 meters * 1km/1,000 meters = 2,890 km/1,000 = 2.89 km
4.4505 km - 2.89 km = 1.5605 km
The length of the fence is 1.5605 km longer than the width of the fence.

Does the quadratic have a maximum or minimum
STALIN [3.7K]

Answer:

B)max/ opens down

Step-by-step explanation:

Parabola equation:

The equation of a parabola has the following format:

y = ax^2 + bx + c

If a > 0, that is, x² is multiplied by a positive number, the function has a minimum value and the parabola opens up.

If a < 0, that is, x² is multiplied by a negative number, the function has a maximum value and the parabola opens down.

In this question:

y = -x^2 - 2x + 3

From the graph, we already see that it opens down and has a max, and analitically, since a = -1 < 0, this is confirmed. The correct answer is given by option b.

Adult red wolves vary in length from 137.16 cm to 168.64 cm. Estimate the difference in length between the longest and shortest
zhannawk [14.2K]

Answer:

As per the statement:

Adult red wolves vary in length from 137.16 cm to 168.64 cm.

To find the difference in length between the longest and shortest of these wolves.

Longest length of wolves = 168.64 cm

Shortest length of wolves= 137.16 cm

Then;

\text{Difference of the length between the longest and shortest of these wolves} = \text{Length of longest wolves} -\text{Length of shortest wolves}

Substitute the given values we have;

\text{Difference of the length between the longest and shortest of these wolves} = 168.64 - 137.16 = 31.48 cm

therefore, the difference in length between the longest and shortest of these wolves is 31.48 cm

If 0.9x-1.3=-3.1, what is the value of x-0.8?
Butoxors [25]
−<span>2.8
</span>Okay so "0.9x-1.3=-3.1" x=-2
 
<span><span><span>0.9x</span>−1.3</span>=<span>−3.1

</span></span>add 1.3 to both sides

<span><span><span><span>0.9x</span>−1.3</span>+1.3</span>=<span><span>−3.1</span>+1.3

</span></span><span><span>0.9x</span>=<span>−1.8

</span></span>divide both sides by 0.9

<span><span><span>0.9x/</span>0.9</span>=<span><span>−1.8/</span><span>0.9

</span></span></span>x=<span>−2</span>

So if you plug in -2 into "x-0.8" you get −2.8

<span>=<span><span>−2</span>−0.8

</span></span><span>=<span><span>−2-</span><span>0.8

</span></span></span><span>=<span>−2.8

</span></span>Hope this helps.
