Answer:

x = 8; y = 2.5.

Step-by-step explanation:

As we know , when two complex numbers are equal their real as well as imaginary part are equal.

So comparing on both sides ,

2x = 16   and    5 = 2y

x = 8       and    y = 2.5.

So ,   x = 8; y = 2.5.

What is the circumference of a circle with a radius of eight inches
stira [4]

Answer:

  • 50.24 inches

\:

Step-by-step explanation:

It is given that, the radius of a circle is 8 inches and we are to find the circumference of the circle.

\:

To find the circumference of the circle we must know this formula first :

\\{ \longrightarrow \qquad{ \underline {\boxed{ \pmb{ \mathfrak{  \: Circumference_{(circle)}= 2 \pi r}}}}}} \: \: \bigstar \\ \\

Where

  • r is the radius of the circle.

  • We'll take the value of π as 3.14

Now substituting the values in the formula :

\\{ \longrightarrow \qquad{  {{\sf{{  \: Circumference_{(circle)}= 2  \times 3.14 \times  8}}}}}} \: \:  \\ \\

{ \longrightarrow \qquad{  {{\sf{{  \: Circumference_{(circle)}=    3.14 \times  16}}}}}} \: \:  \\ \\

{ \longrightarrow \qquad{  { \pmb{\frak{{  \: Circumference_{(circle)}=    50.24}}}}}} \: \:  \\ \\

Therefore,

  • The circumference of the circle is 50.24 inches

Calculate a_57 for the sequence {a_n}={-6,-9/2,-3,-3/2,0}
Archy [21]

Answer:the 57th term is 78

Step-by-step explanation:

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

Tn = a + (n - 1)d

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 = - 6

d =3/2

n = 57

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

T57 = - 6 + (57 - 1) ×3/2

T57 = - 6 + 56 × 3/2 = - 6 + 84

T57 = 78
