A line passes through (1,6) and has a slope of 9

Mathematics
1 answer:
BaLLatris [955]3 years ago
8 0

Answer:

The answer is 9x - y - 3 = 0

Step-by-step explanation:

The line passing through the point (x₁, y₁) and has a slope of m,

y – y₁ m(x – x₁)

where, (x₁, y₁) = (1, 6) and m = 9

y – 6 = (9)(x – 1)

y − 6 = 9x – 9

-9x + y – 6 + 9 = 0

-9x + y + 3 = 0

Divide both side by (-1) we get,

-9x + y + 3/(-1)= 0/(-1)

9x - y - 3 = 0

Thus, The answer is 9x - y - 3 = 0

Two numbers, 3 and a, have a geometric mean of 9. Find the value of a.
Ket [755]
The geometric mean of two numbers x and y is √(xy).

So, if the geometric mean of 3 and a is 9 =>

9 = √(3a)

=> 9^2 = 3a

=> a = 9^2 / 3

a = 81 / 3

a = 27

Answer: the value of a is 27.

At Burnt Mesa Pueblo, archaeological studies have used the method of tree-ring dating in an effort to determine when prehistoric
Zanzabum

Answer:

a) (1215, 1297)

b) (1174,  1338)

c) (1133, 1379)      

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 1256

Standard Deviation, σ = 41

Empirical Rule:

  • Also known as 68-95-99.7 rule.
  • It states that almost all the data lies within three standard deviation for a normal data.
  • About 68% of data lies within 1 standard deviation of mean.
  • About 95% of data lies within two standard deviation of mean.
  • About 99.7% of data lies within 3 standard deviation of mean.

a) range of years centered about the mean in which about 68% of the data lies

\mu \pm 1(\sigma)\\=1256 \pm 41\\=(1215, 1297)

68% of data will be found between 1215 years and 1297 years.

b) range of years centered about the mean in which about 95% of the data lies

\mu \pm 2(\sigma)\\=1256 \pm 2(41)\\=1256 \pm 82\\=(1174, 1338)

95% of data will be found between 1174 years and 1338 years.

c) range of years centered about the mean in which about all of the data lies

\mu \pm 3(\sigma)\\=1256 \pm 3(41)\\=1256 \pm 123\\=(1133, 1379)

All of data will be found between 1133 years and 1379 years.

This figure is made up of a triangle and a semicircle. What is the area of the figure? Use 3.14 for π . Enter your answer, as a
lana66690 [7]
Area of ∆ = 1/2 times its base × height
=1/2 × 4 × 5 UNIT²
=10 unit²
Area of semicircle = πr²/2
= (3.14)(4)²/2
=25.12 unit²

Therefore area of figure= 10+25.12 unit² = 35.12 unit²

Hope it helps!
