Find the 57th term of the arithmetic sequence -13, -29, -45, ...
valina [46]

Answer: the 57 the term is - 909

Step-by-step explanation:

The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + d(n - 1)

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = - 13

d = - 29 - - 13 = - 45 - - 29 = - 16

n = 57

We want to determine the value of the 57th term, T57. Therefore,

T57 = - 13 - 16(57 - 1)

T57 = - 13 - 896

T57 = - 909

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Draw a typical approximating
exis [7]

Answer:

Attached please find response.

Step-by-step explanation:

We wish to find the area between the curves 2x+y2=8 and y=x.

Substituting y for x in the equation 2x+y2=8 yields

2y+y2y2+2y−8(y+4)(y−2)=8=0=0

so the line y=x intersects the parabola 2x+y2=8 at the points (−4,−4) and (2,2). Solving the equation 2x+y2=8 for x yields

x=4−12y2

From sketching the graphs of the parabola and the line, we see that the x-values on the parabola are at least those on the line when −4≤y≤2.
