Answer:

The object is at rest.

Step-by-step explanation:

Distance may be defined as the the total path length covered by the object. Speed may be defined as the distance covered by the object per unit time by the body.

The distance time graph indicates the different line on the graph. The distance time graph that has straight line shows that object is at rest and the object is not moving at all.

Thus, the answer is object is at rest.

A distance-time graph tells us how far an object has moved with time. The steeper the graph, the faster the motion. A horizontal line means the object is not changing its position - it is not moving, it is at rest. A downward sloping line means the object is returning to the start.

Find all zeros of ƒ(x) = 2x^4 – 72x^2. Then determine the multiplicity at each zero. State whether the graph will touch or cross

AleksandrR [38]

Answer: See below

Step-by-step explanation:

To find the factor,

f(x) = 0

$\begin{aligned}&2 x^{4}-72 x^{2}=0 \\&2 x^{2}\left(x^{2}-36\right)=0 \\&x^{2}\left(x^{2}-36\right)=0 \\&x \times x \times(x-6) \times(x+6)=0 \\&\mathrm{x}=0,0,6,-6\end{aligned}$

So,

x = 0 multiplicity 2

x = -6 multiplicity 1

x = 6 multiplicity 1

For an even multiplicty, the graph touches the x-axis, and for an odd multiplicty, the graph crosses the x-axis

Therefore,

x = 0 multiplicty 2, Touch

x = -6 multiplicty 1, Cross

x = 6 multiplicty 1, Cross

Identify the explanatory and response variables in the following situation:

zhannawk [14.2K]

Negative correlation refers to an inverse relationship between two variables. When one variable increases, the other decreases.

The variables are latitude and average temperature.

The explanatory variable is latitude and the response is the average temperature. Choice B.

As the latitude increases, the average temperature decreases. This is a strong negative correlation of between the two variables.

The average of three different positive integers is 8. What is the largest integer that could be one of them?

galina1969 [7]

Answer:22

Step-by-step explanation: the smallest the other two can be is 1 so you have to multiply 8 with 3, that equals 24, then you have to subtract 2 (1+1) and that gives you 22.

If you deposit $10,000 at 3.85% interest, compounded daily, what would your ending balance be after three years?

stepladder [879]

Answer: $11,155

Step-by-step explanation: For this problem, first we will use the "Simple Interest" equation to find the total interest earned after three years.

First, convert 3.85% to a decimal, 0.0385.

I, interest = 10,000 x 0.0385 x 3

I = 1,155

Now add the total interest $1,155 to the total deposit $10,000.

1,155 + 10,000 = $11,155
