Imagine that we put a raisin cake into the oven, with each raisin separated from the others by 1 cm. an hour later, we take it o
ut and the distances between raisins are 3 cm. if you lived in one of the raisins and watched the other raisins as the cake expanded, which of the following would you conclude? - all raisins would be moving away from you at the same speed. - it depends: if you lived in a raisin near the left side of the cake, you'd see other raisins moving away from you, but they'd be coming toward you if you lived in a raisin near the right side of the cake.- more distant raisins would be moving away from you faster. - more distant raisins would be moving away from you more slowly.

Answer:
All raisins would be moving away from you at the same speed, without any dependence
Step-by-step explanation:
As you can see in the graph it is irrelevant if they are on one side or another of the cake since you would see everyone moving away from you at the same speed since the cake must undoubtedly expand to establish a distance of 3cm between the raisins .
Note: It should be understood that the dough should be uniform and the ideal cooking conditions for a standard cake

<span><span>1.A triangular section of a lawn will be converted to river rock instead of grass. Maurice insists that the only way to find a missing side length is to use the Law of Cosines. Johanna exclaims that only the Law of Sines will be useful. Describe a scenario where Maurice is correct, a scenario where Johanna is correct, and a scenario where both laws are able to be used. Use complete sentences and example measurements when necessary.
</span>
The Law of Cosines is always preferable when there's a choice. There will be two triangle angles (between 0 and 180 degrees) that share the same sine (supplementary angles) but the value of the cosine uniquely determines a triangle angle.
To find a missing side, we use the Law of Cosines when we know two sides and their included angle. We use the Law of Sines when we know another side and all the triangle angles. (We only need to know two of three to know all three, because they add to 180. There are only two degrees of freedom, to answer a different question I just did.

</span>
We'll use the standard parabola, oriented in the usual way. In that case the directrix is a line y=k and the focus is a point (p,q).
The points (x,y) on the parabola are equidistant from the line to the point. Since the distances are equal so are the squared distances.
The squared distance from (x,y) to the line y=k is </span>

The squared distance from (x,y) to (p,q) is </span>

Answer:
48
Step-by-step explanation:
is basically the horizontal axis.
First, find the integral of x^2-25.
Remember that
integral of a constant is that constant times x.
Also that
to take the integral of a power function, add 1 to the degree and divide by that same degree.
We then get
Evaluate at -3
Then we evaluate at 0
Next, we subtract the the answer then we get
