(will mark brainliest!!) The table shows the relationship between time spent running and distance traveled. A 2-column table wit

h 5 rows. The first column is labeled time (minutes) with entries 1, 2, 3, 4, 5. The second column is labeled distance (feet) with entries 530; 1,050; 1,600; 2,110; 2,650. Which type of model best describes the relationship?
a) linear, because the r value for the linear model is closest to 1
b) exponential, because the r value for the exponential model is closest to 0 c) linear, because the rate of change between each pair of points is exactly 520 d) exponential, because the rate of change between each pair of points is 1.98

Solve for x. write both solutions separated by a comma. 2x^2-5x+2=0​
Nataly [62]

BY USING MIDDLE TERM SPLITTING,

2x^2-(4x+x)+2=0

(2x^2-4x)-(x-2)=0

2x(x-2)-1(x-2)=0

(2x-1)(x-2)=0

Two solutions are 2, 1/2

A particle moves along the curve below. y = √ 8 + x 3 As it reaches the point ( 1 , 3 ) , the y -coordinate is increasing at a r
Dmitry [639]

Answer:

<em>The x-coordinate is changing at 10 cm/s</em>

Step-by-step explanation:

<u>Rate of Change</u>

Suppose two variables x and y are related by a given function y=f(x). If they both change with respect to a third variable (time, for instance), the rate of change of them is computed as the derivative using the chain rule:

\displaystyle \frac{dy}{dt}=\frac{dy}{dx}\cdot \frac{dx}{dt}

We have

y=\sqrt{8+x^3}

Or, equivalently

y^2=8+x^3

We need to know the rate of change of x respect to t. We'll use implicit differentiation:

\displaystyle 2y\cdot \frac{dy}{dt}=3x^2\cdot \frac{dx}{dt}

Solving for dx/dt

\displaystyle \frac{dx}{dt}=\frac{2y\cdot \frac{dy}{dt}}{3x^2}

Plugging in the values x=1, y=3, dy/dt=5

\displaystyle \frac{dx}{dt}=\frac{2(3)\cdot 5}{3\cdot 1^2}=10

The x-coordinate is changing at 10 cm/s
