Answer:

x-9 = ±9

Step-by-step explanation:

(x – 9)^2 = 81

Take the square root of each side

sqrt((x – 9)^2 = ±sqrt(81)

x-9 = ±9

Add 9 to each side

x-9+9 = 9 ±9

x = 9+9   and 9-9

x = 18,0

in a diagram of a landscape plan the scale is 1 cm 10 ft in the diagram the trees are 5.2 cm apart. how far apart should the act
vazorg [7]
The scale of the drawing is 1 cm to 10 feet. This means, every 1 cm of the drawing represents 10 feet in actual.

The trees are 5.2 cm apart in the drawing. So according to the given scale, they will be 5.2 x 10 = 52 feet apart in actual.

So actual bushes be planted at a distance of 52 feet.

What is the equation of the line passing through the points (2, –1) and (5, –10) in slope-intercept form?y=-3x-5y=-3x+5y=3x-5 y=
mars1129 [50]
Find the slope:
m=y2-y1/x2-x1
m=-10--1/5-2
m=-9/3
m=-3

If you plug in points (for x and y) into the second equation, you will notice that it results in true statements.

Therefore, your answer is the second choice:
y=-3x +5

"jimi has 5000 songs on his ipod shuffle, which picks songs uniformly at" random. jimi plans to listen to 100 songs today. what
Furkat [3]

Answer:

  about 63.1%

Step-by-step explanation:

For the first song, it is certain it isn't a duplicate. For the second song, the probability that it is not a duplicate is 4999/5000. The probability the third song is not a duplicate is 4998/5000.

Hence the probability that none of the 100 songs is a duplicate is ...

  5000!/4900!/5000^100 ≈ 0.369120

Then the probability that one or more is a duplicate is ...

  1 - 0.369120 ≈ 0.630880
