Answer:
Step-by-step explanation:
A dilation is an enlargement or reduction of an object by a scale factor and with a center of dilation. The scale factor refers to the change in size. The center of dilation is a point about which we are dilating an object.
The dilation with the center of dilation at the origin and a scale factor of k has the rule
This means that the image of the point with coordinates (x,y) after the dilation by a scale factor of k with center of dilation at origin will have coordinates (kx,ky).

Answer:
The 26th term of an arithmetic sequence is:
Hence, option A is true.
Step-by-step explanation:
Given
- a₁ = -33
- d = 4
An arithmetic sequence has a constant difference 'd' and is defined by
substituting a₁ = -33 and d = 4 in the nth term of the sequence
Thus, the nth term of the sequence is:
now substituting n = 26 in the nth term to determine the 26th term of the sequence
Therefore, the 26th term of an arithmetic sequence is:
Hence, option A is true.
