Notice the dependent and independent variables. X axis is usually the independent while y is the dependent. The dependent variable is affected by the independent one. Ravi is driving at a constant speed, which one looks like it is not changing in any direction whatsoever? But, Ravi is speeding up, so which one is adding the speeding (moving up) part of Ravi's driving? And finally, what graph also showcases the visual of Ravi slowing down after he was driving at a constant speed and then speeding up (hint: straight, up, down)?

<h2>Answer:</h2>

$f^{-1} (x)=\sqrt{\frac{x}{14}}$ .

<h2>Step-by-step explanation:</h2>

<h3>1. Write the expression.</h3>

$y=14x^2$

<h3>2. Substitute y for x, and x for y.</h3>

$x=14y^{2}$

<h3>3. Solve for y.</h3>

$14y^{2}=x\\ \\y^{2} =\frac{x}{14} \\ \\y=\sqrt{\frac{x}{14}}$

<h3>4. Express your result.</h3>

$f^{-1} (x)=\sqrt{\frac{x}{14}}$ .

Write an explicit formula for the sequence 3,-9,27,-81

Dominik [7]

The initial value is 3. The common ratio is -9/3 = -3. The general formula is
.. an = a1*r^(n-1)

So, for your values, ...
.. an = 3*(-3)^(n -1)

Dana saved 450 for food for her upcoming vacation. The breakfast was included with their hotel, but lunch and dinner are not. Wh

zzz [600]

Answer:

$10d + 40r \leq 450$

Step-by-step explanation:

Given

$Savings = 450$

$Dana\ Cooks, d = 10$

$Restaurant, r = 40$

Required

Represent this as an inequality

When Dana cooks;

$Cost\ per\ meal = 10$

$Cost\ per\ d\ meals = d * 10$

$Cost\ per\ d\ meals = 10d$

At Restaurant

$Cost\ per\ meal = 40$

$Cost\ per\ r\ meals = 40 * r$

$Cost\ per\ r\ meals = 40 r$

Add these two results:

$Result = 10d + 40r$

<em>To represent as an inequality, the above result must be less than or equal to Dana's total savings</em>

i.e.

$10d + 40r \leq 450$
