Answer:

  • x - 7.31 ≤ 10
  • x ≤ 17.31

Step-by-step explanation:

let x = the amount of money in the second piggy back

We assume that the second piggy bank has MORE than the piggy bank with $7.31 in it:

x - 7.31 ≤ 10

<u>Solution</u>

Add 7.31 to both sides:  x - 7.31 + 7.31 ≤ 10 + 7.31

                                                       ⇒ x ≤ 17.31

B. 237,600 people. You would find the Square feet of one side of the street. Which is length times width. 15,840ft (3 miles)x 30 ft. Double the the amount to count for the other side of the street, then divide by 40 and multiply by 10.

Una elipse se describe segun la ecuacion (x-2)2 +(y-1)2 halla las coordenadas de los vertices, focos, las longitudes de las ejes
galina1969 [7]

Answer:

The equation of the ellipse is

\frac{(x-2)^{2} }{100} +\frac{(y-1)^{2} }{36} =1

This is the explicit form of an ellipse, where h=2 and k=1, which means the center of the ellipse is at C(2,1).

Remember that the greatest denominator in an ellipse is the parameter a^{2} and the least is b^{2}, so

a^{2}=100 \implies a=10\\ b^{2}=36 \implies b=6

The length of the major axis is: 2a=2(10)=20

The length of the minor axis is: 2b=2(6)=12

Vertices are (-8,1) and (12,1), because the center is not the origin of the coordinate system so, the vertices are displaced. The least axis vertices are: (2,7) and (2,-5).

The foci are on the major axis, so their vertical coordinate is 1, their horizontal coordinate depends on parameter c, which is related as the following

a^{2}=b^{2}  +c^{2} \\100-36=c^{2}\\ c=\sqrt{64}\\ c=8

Therefore, the foci coordinates are F(10,1) and F'(-6,1).

The ladus rectus is

LR=\frac{2b^{2} }{a}=\frac{2(36)}{10}=7.2

The eccentricity is

e=\frac{c}{a}=\frac{8}{10}=0.8

Additionally, the graph is attached, there you can observe some elements of the ellipse.

(Remember, all elements of an ellipse depend on the three parameters a, b and c, that's what you need to find first)
