Answer:

Ah! Geometric sequences, Eh? Sucks I know....

Step-by-step explanation:

So first, we need to find the factor of this(been a while since I have done this)

r=\frac{24}{48} =\frac{1}{2}

So we found the relationship! Now we find the entire equation.

So we know the first term, 96, so let's use it!

a_{n} =96*(\frac{1}{2})^{n-1}

So there is the equation!

Now to find the 10th term.

a_{n} =96*(\frac{1}{2})^{n-1}\\a_{10} =96*(\frac{1}{2})^{9}\\a_{10} =96*\frac{1}{2^{9} } \\a_{10}=0.1875

There you have it!

Hope this Helps!

P.S. Stay Safe!

Using the data below, what is the equation for the line of best fit? Remember, put your answer in y = ax + b form and round any
ratelena [41]
If we fit the data as calories as a function of wt loss/week, we need to arrange the data first from lowest to highest wt loss/week lbs and calories. Then, the set of points can be plotted in a graph and a graphical method of line fitting can be used. Curve fitting programs (which are also in the calculator) can be used. The result is:
y = -266.5741x + 2246.5116

The value of R² is 0.7109. The fit is not very good since R² is quite far from 0.99.

Need help with a math question
tatyana61 [14]

ANSWER

x = 71 \degree

EXPLANATION

The sum of the exterior angles of a polygon is 360°

The angles were given in terms of x.

We add all and equate to 360° to obtain.

x + (x - 6) + (x + 4) + (x + 2) + (x + 5) = 360 \degree

This implies that,

5x + 5 = 360

5x = 360 - 5

5x = 355

x  = \frac{355}{5}

x = 71 \degree

What is 34 less than the product of 14 and a unknown number of is 78. what is the unknown number?
AysviL [449]
It is extremely important to understand the words of the given problem. There are numerous information's of immense importance that are already given in the question. Based on those information's the answer to the question can be easily deduced.
Let us assume the unknown number = x
Then
14x - 34 = 78
14x = 78 + 34
14x = 112
x = 112/14
  = 8
So the unknown number in the given question is 8. I hope the procedure is clear to you and you got the answer that you wanted.

Easy Geometry <br> Please help
Sidana [21]

Description about easy geometry is given below

Step-by-step explanation:

1.The basic geometric objects that create shapes like : points, lines, line segments, rays, and planes. A point is represented by a dot and shows a location in space.

2.Geometry is easier and it was easier to study for. Algebra is more focused on equations while the things covered in Geometry really just have to do with finding the length of shapes and the measure of angles.

3.In two dimensions there are 3 geometries:

  • Euclidean,
  • spherical, and
  • hyperbolic.

4.A point in geometry is a location. ... A point is shown by a dot. A line is defined as a line of points that extends infinitely in two directions. It has one dimension, length. Points that are on the same line are called collinear points.
