The complete arithmetic sequence is 1, .25, -0.5, -1.25, -2

The arithmetic sequence is given as:

1, .25, blank, -1.25, blank

Replace the blanks in the arithmetic sequence with x and y

So, we have:

1, .25, x, -1.25, y

An arithmetic sequence has a common difference (d)

The common difference is calculated using

d = T2 - T1

So, we have

d = 0.25 - 1

d = x - 0.25

d = y + 1.25

Substitute d = x - 0.25 in d = 0.25 - 1

x - 0.25 = 0.25 - 1

This gives

x = 0.25 + 0.25 - 1

Evaluate the sum

x = -0.5

Substitute d = 0.25 - 1 in d = y + 1.25

0.25 - 1  = y + 1.25

This gives

y = 0.25 - 1 - 1.25

Evaluate

y = -2

Hence, the complete arithmetic sequence is 1, .25, -0.5, -1.25, -2

The answer choice which represents the length to swim diagonally and expressed to the nearest tenth as required in the task content is; Choice D; 14.2 meters.

It follows from the task content that the pool in discuss is rectangular and hence, the diagonal of the rectangle makes a right triangle with two perpendicular sides of the rectangle.

Hence, from Pythagoras theorem; we have;

hyp² = opp² + adj²

Hence,

D² = 9² + 11²

D² = 81 + 121

D² = 202

D = √202

The correct question is given below:
A health and fitness company is testing a newly designed exercise and weight loss program. It is suspected that the new program is more effective in assisting weight loss. A group of 220 volunteers is first separated into 6 groups, labeled A to F, based upon age and weight such that these qualities are similar within each group. The age and weight of the volunteer is initially measured. Within each group, participants are randomly assigned to either undergo the new exercise program or undergo a conventional exercise program. In addition, the daily calorie intake is set to a particular amount, either low, moderate or high, and maintained at that level for the duration of the program. At the end of six months, the percentage of weight lost is measured for each unit and the results are collected and compared.

The cliff is 98.89 feet tall.

In the attached diagram, we can there are two triangles forming. Small triangle involves Juan and tent and larger triangle involves Juan and cliff. As per the known fact, tan theta = perpendicular ÷ base. So, tan theta will be common for both the triangles. Hence, relating the components of tan theta, of both the triangles.

Smaller triangle :

tan theta = 10/45

Larger triangle :

tan theta = h/(400 + 45)

tan theta = h/445

Relating both the triangles as follows -

10/45 = h/445

Performing cross multiplication

10×445 = h×45

h = 4450÷45

h = 98.89 feet

The change in the elevation from the bottom of the Ferris is 21.9 feet.

Elevation change refers to the difference in elevation between the beginning and end of your route.

Given that the distance travelled by Vivian just at bottom of the elevation is -9.6 feet.

The distance traveled by Vivian at the top of the elevation is 12.3 feet.

Vivian's shift in elevation would be expressed as the difference between the elevations at the bottom and top.

Let Ei be the initial elevation of -9.6 feet.

Ef = 12.3 feet as the final elevation

Change in elevation;

ΔE = Ef - Ei

ΔE = 12.3 - (-9.6)

ΔE = 12.3 + 9.6

ΔE = 21.9 feet

Therefore, the change in the elevation is found to be 21.9 feet.

Answer:

[tex]y = 120x [/tex]

Step-by-step explanation:

Equation of a straight line is

[tex]y = mx + b[/tex]

m= slope of line = rise/run which can be computed by taking two points on the line, finding the difference I the y coordinate values and dividing by the correspoding difference in their x coordinate values

b is the y-intercept where the line crosses the y-sxis

Looking at the graph we can see that the line crosses the y-sxis at the origin (0, 0) so the y-intercept is at y=0

The slope is determined by examining the two highlighted points (3, 360) and (2, 240)

Slope =

[tex] \frac{360 - 240}{3 - 2} = \frac{120 }{1} = 120[/tex]

So equation of line is

[tex]y = 120x + 0[/tex]
