What will be the y - coordinate of b' if ab is dilated by a factor of 2/5, centered at origin?

When the dilation of a line or is centered at the origin, both the x and y coordinates are multiplied by the same value, k (which represents the scale or ratio of dilation)

If ab is dilated by a factor of 2/5 to produce a’b’, then k = 2/5

Since the dilation is centered at origin,

The y-coordinate of b' what will be 2/5 of the y-coordinate of b.

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
