Answer:

243000000 = (x+3)² × 3

x = 8997 cm or 89.97 m

Step-by-step explanation:

Volume of a prism = Base area × height

Volume = 243m³ = 243×100³ cm³

Volume = 243000000 cm³

(Since the dimensions are in cm, I've converted the volume in cm³)

Base is a square: Base area = side²

The equation is:

243000000 = (x+3)² × 3

(x+3)² = 243000000 ÷ 3

(x+3)² = 81000000

If need to solve further,

(x+3) = 9000

x = 8997 cm or 89.97 m

Given the graph of a scatterplot and a trend line, explain how you would find the equation of the trend line.
SpyIntel [72]

To find the equation of a trend line, It is important to find the X axis and Y axis, Once x axis and y axis  is found if there is an association between x axis and y axis, We use linear equation to produce the trend line. Linear regression or algorithm called as OLS (Ordinary least square). Y= mx +c

y = dependent variable, x = independent variable , constant = c , m  = y2-y1/x2-x1.

Step-by-step explanation:

  • Scatter plot is to find association of two different variable.
  • Trend line is the equation between xaxis and y axis.
  • Prediction is best way to form equation.
  • Linear regression y=mx +c
  • Equation helps in predictive modelling between next best form.
  • Y is a dependent variable or example sales.
  • X can be n number of variable involved in the association rule.
  • Linear regression is starting phase of data analysis.
  • C = constant there is a certain point, where system has been started.
  • Stock market did not start from 0 it started at a certain point.

Divide the square root of 81 by the difference between the product of-1 and -3 and the square root of 4​
kherson [118]

Answer:  \frac{9}{1}

Step-by-step explanation:

FIrst find the square root of 81.

\sqrt{81}  = 9  

The square root of 81 is 9.

FInd the product of -1 and -3 by multiplying the -1 by -3.

-1 * -3 = 3

next find the square root of 4.

     

   \sqrt{4} = 2  

Now it said divide  the square root of 81 which is 9 by  the difference between 3 and 2 and the difference between 3 and 2 two is 1.  

Thos means that the answer will be 9/1.
