f(x) = -2x + 2

g(x) = (1/3)^x + 1

f(x) = g(x)

-2x + 2 = (1/3)^x + 1

-2x + 2 = 3^(-x) + 1

3^(-x) + 2x + 2 - 1 = 0

3^(-x) + 2x + 1 = 0

We don't know how to solve this, right? But we can analyse the graph. We see that both f(x) and g(x) find each other in two points, (0, 2) and (-1, 4)

So we can say that x = -1 and x = 0 are solutions for this equation.

A video game developer wants to know how long it takes people to finish playing their new game. They surveyed a random sample of

Nadya [2.5K]

Based on the data, the median time it takes players to complete the game is 1148 minutes.

<h3>What is the median?</h3>

It is the mathematical value that is the middle when values are sorted.

<h3>How to find the median time?</h3>

Organize the values

457 - 548- 866 - 952 - 976 - 1037 - 1148 - 1235 - 1245- 1431-1486 - 1759 - 1864

Identify the value of the middle

Considering there are 13 values, the value of the middle is the value number 7 or 1148.

Note: This question is incomplete because the data is missing, below I attached the missing section,

Gravel is being dumped from a conveyor belt at a rate of 15 ft3/min, and its coarseness is such that it forms a pile in the shap

gayaneshka [121]

Answer:

0.13 ft/min

Step-by-step explanation:

We are given that

$\frac{dV}{dt}=15ft^3/min$

We have to find the increasing rate of change of height of pile when the pile is 12 ft high.

Let d be the diameter of pile

Height of pile=h

d=h

Radius of pile,r= $\frac{d}{2}=\frac{h}{2}$

Volume of pile= $\frac{1}{3}\pi r^2 h=\frac{1}{12}\pi h^3$

$\frac{dV}{dt}=\frac{1}{4}\pi h^2\frac{dh}{dt}$

h=12 ft

Substitute the values

$15=\frac{1}{4}\pi(12)^2\frac{dh}{dt}$

$\frac{dh}{dt}=\frac{15\times 4}{\pi(12)^2}$

$\frac{dh}{dt}=0.13ft/min$
