Answer and explanation:

Assuming the frog jumps from -10 for all jumps, if the frog decides to make all 4 jumps then :

8 units jump= -2 or -18

4 units jump= -6 or -14

2 units jump= -8 or -12

1 unit jump = -9 or -11

If the frog decides to make one jump then skip the others then:

Either it makes 8 units jump= -2 or -18

Or 4 units jump= -6 or -14

Or 2 units jump= -8 or -12

Or 1 unit jump = -9 or -11

If it decides to make 2 jumps and skip the others then:

Either it makes 8 units jump= -2 or -18

and 4 units jump= -6 or -14

Or 2 units jump= -8 or -12

and 1 unit jump = -9 or -11

Or any other mix of units of jump twice

If it decides to make 3 jumps and skip the others then:

Either it makes 8 units jump= -2 or -18

and 4 units jump= -6 or -14

and 2 units jump= -8 or -12

Or 1 unit jump = -9 or -11

and 4 units jump= -6 or -14

and 2 units jump= -8 or -12

Or any other mix of 3 jumps

If it decides to make no jump at all then the frog would remain at -10

Substitute in the values for (x1,y1)and (x2,y2).

(-2+2/2,[tex]\frac{4+6}{2}[/tex])

Cancel the common factor of −2+2 and 2.

(−1+1, [tex]\frac{4+6}{2}[/tex])

Add −1 and 1.

(0,[tex]\frac{4+6}{2}[/tex])

Cancel the common factor of 4+6 and 2.

(0, 2+3)

Add 2 and 3.

Step-by-step explanation:

x^2/12.25 + y^2/4 = 1

A carpenter designs a tabletop in the shape of an ellipse 7 feet long and 4 feet wide then, the equation of that ellipse would be [tex]\dfrac{ x^2}{12.25} + \dfrac{ y^2}{4} = 1[/tex]

Suppose that the major axis is of the length 2a units, and that minor axis is of 2b units, and let the ellipse is centered on (h,k) with a major ellipse parallel to x-axis, then the equation of that ellipse would be:

[tex]\dfrac{(x-h)^2}{a^2} + \dfrac{(y-k)^2}{b^2} =1[/tex]

Coordinates of its foci would be: [tex](h \pm c, k)[/tex]  where   [tex]c^2 = a^2 - b^2[/tex]

If its major axis is parallel to y-axis, then,

Coordinates of its foci would be: [tex](h , k\pm c)[/tex] where [tex]c^2 = a^2 - b^2[/tex]and its equation would be:

[tex]\dfrac{(x-h)^2}{b^2} + \dfrac{(y-k)^2}{a^2} =1[/tex]

A carpenter designs a tabletop in the shape of an ellipse 7 feet long and 4 feet wide.

The carpenter sketches a drawing of the tabletop on a coordinate plane.

The center of the tabletop is at the origin, the length falls along the x-axis, and the width falls along the y-axis.

then, the equation of that ellipse would be:

[tex]\dfrac{ x^2}{12.25} + \dfrac{ y^2}{4} = 1[/tex]

#SPJ2

Answer:

Number of students in a student group = 8

Step-by-step explanation:

Let number of student in a student group = x

∴ Kevin lead 150 adults and 6x students

⇒Kevin lead = 150 + 6x

And,

Monica lead 134 adults and 8x students

⇒Monica lead = 134 + 8x

So, the number of students are equal

⇒150 + 6x = 134 + 8x

⇒150 - 134 = 8x - 6x

⇒16 = 2x

⇒x = [tex]\frac{16}{2}[/tex] = 8

∴ we get

Number of students in a student group = 8

Answer:

y = 2/3

Step-by-step explanation:

14 = 6(2) + 3y

14 = 12 + 3y

2 = 3y

y = 2/3

The notation according to the set will be "[tex][5, + \infty) \cup (- \infty , 7][/tex]".

Let,

∴ [tex]x \ \epsilon \ R[/tex]

Now,

hence,

→ [tex]x \leq 7 \rightarrow (- \infty, 7][/tex]

→ [tex]x \geq 5 \rightarrow [5, + \infty)[/tex]

then,

The notation will be:

→ [tex][5, + \infty) \cup (- \infty , 7][/tex]

Answer:

x=92

Step-by-step explanation:

those to angles are supplementary meaning that they add up to equal 180

so you set up the equation 180=x+x-4

180=2x-4

step 1 add 4 to each side

184=2x

step 2 divide each side by 2

x=92

so the angles equal 92 and 88

Answer:

92°

Step-by-step explanation:

180 degrees on a straight line.

2x - 4 = 180

2x = 184

X = 92°

Answer: 10.375

Step-by-step explanation:

mean = average

Finding the average, means you need to add all the numbers up, and then divide it by the total amount.

-------------------------------------------------------------------------------

First Step: add them up

19+2+14+8+11+10+4+15=83

Second Step: count the amount of numbers

8 numbers in total

Third Step: divide the total amount over numbers

83/8=10.375
