Answer:

Sally ends at 3 feet below zero point.

Step-by-step explanation:

Let be h the height with respect to zero point, which is represented by the following sum:

h = \Sigma_{i=1}^{n} h_{i}

Where:

h_{i} - i-th travelled height, measured in feet.

In addition, positive sign means ascension, whereas negative sign means descent.

The statement can be translated into the following mathematical identity:

h = h_{1}+h_{2}+h_{3}+h_{4}

h = 224\,ft+(-131\,ft)+67\,ft -163\,ft

h = -3\,ft

Sally ends at 3 feet below zero point.

I NEED HELP PLSSSSSSSS
AVprozaik [17]

Answer:

X >>>>> Y

–1 >>>> 16

0 >>>>> 8

1 >>>>> 4

2 >>>>> 2

3 >>>>> 1

Step-by-step explanation:

From the question given above,

y = 8 × (½)ˣ

When x = –1, y =?

y = 8 × (½)ˣ

y = 8 × (½)¯¹

y = 8 × 2

y = 16

When x = 1, y =?

y = 8 × (½)ˣ

y = 8 × (½)¹

y = 8 × ½

y = 4

When x = 2, y =?

y = 8 × (½)ˣ

y = 8 × (½)²

y = 8 × ¼

y = 2

When x = 3, y =?

y = 8 × (½)ˣ

y = 8 × (½)³

y = 8 × ⅛

y = 1

SUMMARY:

X >>>>> Y

–1 >>>> 16

0 >>>>> 8

1 >>>>> 4

2 >>>>> 2

3 >>>>> 1

Y+2=−3(x−4)<br> Complete the missing value in the solution to the equation.
My name is Ann [436]

y+2=-3x+12

 -2        -2

y=-3x+10

This is as far as it can be simplified.
