Answer:

x=196

Step-by-step explanation:

In order to solve this you just have to clear X fro the equation and solve:

2\sqrt{x} - 5=2\\ 2\sqrt{x}=2+5\\\sqrt{x}=7*2\\x=14^2\\x=196Once you´ve calculated this you have the solution for the equation, that is x.

It is not an extraneous solution.

Ethan rollerbladed a total of 623 \text{ km}623 km623, start text, space, k, m, end text over ddd days. He rollerbladed the same
Sever21 [200]

Answer:

Ethan rollerbladed each day  \frac{623}{d}  kilometers.

Step-by-step explanation:

Given:

Ethan rollerbladed a total of 623 km over d days.

Now, to find the kilometers Ethan rollerblade each day.

Total number of distance rollerbladed = 623 km.

Total number of days = d.

<u><em>As, Ethan rollerbladed each day the same distance.</em></u>

Now, to get the distance Ethan rollerbladed in each day we divide total number of distance rollerbladed by total number of days:

Ethan\ rollerbladed\ each\ day\ =\ \frac{Total\ number\ of\ distance\ rollerbladed}{Total\ number\ of\ days}

Ethan\ rollerbladed\ each\ day\ =\ \frac{623}{d}

Therefore, Ethan rollerbladed each day \frac{623}{d}  kilometers.

The scatter plot shows the profit by the month for a new company during its first year of operation. Which equation most closely
kondor19780726 [428]

The equation most closely models the line of best fit for the scatter plot is y = 2.5x

<h3>Equation of a line</h3>

A line is the distance between two points. The equation of a line in point-slope form is given as y =mx + b

  • m is the slope
  • b is the intercept


Using the coordinate points on the line (3, 5000) and (9, 20000)

Get the slope

Slope = 20000-5000/9-3
Slope = 15000/6 = 2500

Determine the y-intercept

5000 = 2500(3) + b

b = 5000 - 7500
b = -2500

Determine the equation

y = 2.5x - 2.5

Hence the equation most closely models the line of best fit for the scatter plot is y = 2.5x

F(x)=x^2. What is g(x)
xxTIMURxx [149]

Answer:

g(x) = \frac14x^2

Step-by-step explanation:

Since f(x) and g(x) share the same top at (0,0), their difference is only a scale factor, so g(x) = ax² but we need to find a.

To find it, we use the given point of g, (2,1)

So g(2) = 1

meaning that

a·2² = 1

4a = 1

a = 1/4

y = β0 + β1x1 + β2 x12+ ε ​is known as a Group of answer choices simple first-order model with two predictor variables. simple f
Alborosie

Answer:

(A)Simple First Order Model with Two Predictor Variables.

Step-by-step explanation:

A multiple linear regression model with k predictor variables X₁, X₂, ..., Xₖ and a response Y, can be written as:

y = βₒ + β₁x₁ + β₂x₂ + ··· βₖxₖ + ∈.

Where:

x₁ , x₂,...xₖ are the predictor variables.

βₒ ,β₁, β₂ ··· βₖ are the Regression Coefficients.

and ∈ are the residual terms of the model

Multiple regression models describe how a single response variable y depends linearly on a number of predictor variables x.

The model:

y = βₒ + β₁x₁ + β₂x₂ + ∈ has two predictor variables. It is also of first order since there is no quadratic term, therefore it is a Simple First Order Model with Two Predictor Variables.
