Consider the sequence below
GalinKa [24]

Answer: option D is the correct answer

Step-by-step explanation:

In the given sequence, the consecutive terms differ by a common difference.

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 = - 351

d = - 343 - - 351 = - 343 + 351

d = 8

Therefore, the explicit function which defines the sequence is

f(n) = - 351 + 8(n - 1)

f(n) = 8n - 8 - 351

f(n) = 8n - 359

Show that the triangle below is not a right-angled triangle.
Paha777 [63]

Step-by-step explanation:

A right triangle is a triangle in which one of the angles is a 90∘ angle.

(5x - 8)  + (2x - 5)  + (2x  + 3) = 180 \\ 9x - 10 = 180 \\ 9x = 190 \\ x =  \frac{190}{9}  \\ x = 21.11

(5x - 8) =97.56  \\ (2x - 5)  =37.22  \\ (2x + 3) =45.22  \\

Since None of the angels is 90° , so the triangle is not a right triangle.

90 degrees to radian
insens350 [35]

To convert degrees to radians  multiply degrees by pi/180.

So 90 degrees = 90pi/180  = pi/2 radians   or  1.57 radians to the nearest hundredth.
