Does anyone know the minim value of the function f(x) =2x^2 -4x -6?. I’m online due to my quarantine and am looking for extra he
navik [9.2K]

Answer:

f(x) = - 8

Explanation:

The given function is

f(x) =2x^2 -4x -6

The first step is to find the derivative of the function. Recall, if

y = ax^b

y' = abx^(b - 1)

Thus,

f'(x) = 4x - 4

We would equate f'(x) to zero and solve for x. We have

4x - 4 = 0

4x = 4

x = 4/4

x = 1

We would substitute x = 1 into the original function and solve for f(x) or y. It becomes

f(1) =2(1)^2 -4(1) - 6 = 2 - 4 - 6

f(1) = - 8

Thus, the minimum value is f(x) = - 8

What is the extracts volume of the largest cone that can fit into a cube with edges of 10 inches
Aneli [31]
Volume of a cone = π r² h/3

I envisioned a cone inside a cube. I only identified the necessary value to compute for the exact volume of the largest cone.

Edges of the cube is 10 inches. When the circle part of the cone is placed in the circle, the diameter would be 10 inches also. I divided it by 2 to get the value of the radius, resulting to 5 inches.

The height of the cone is also the height of the cube. Thus, it is 10 inches.

Volume of the cone = 3.14 * (5in)² * 10in/3
V = 3.14 * 25in² * 3.33 in
V = 261.405 in³ or 261.41 in³  VOLUME OF THE LARGEST CONE THAT CAN FIT IN A 10 INCH CUBE

Write an equation in slope-intercept form of the line shown.
Liula [17]

Answer:

Step-by-step explanation:

y2-y1/x2-x1

1+3

3-1

your slope is 4/2 or 2. keep going down to find what y is when x is 0, which happens to be -5

so now you have a slope and a y intercept you can solve  like y=mx+b where m is your slope and B is your y intercept

y=2x-5 is your answer

Answer:

Expected population in 2015: 19,152.58 or 19,000 people

Step-by-step explanation:

Given the decreasing rate of 2.5% per year, and a population of 28,000 in the year 2000:

We can solve for the rate of decrease by using the formula:

A = a(1 - r )^{t}

where:

A = population by year 2015

a = initial population (in year 2000) = 28,000

r = rate of change (decrease by 2.5% annually or 0.025)

t = time (in number of years) = 15

Plug in these given values into the formula:

A = a(1 - r )^{t}

A = 28,000(1 - 0.025 )^{15}

A = 28,000(0.975)^{15}

A = 28,000(0.684)

A = 19,152.58 or about 19,000 people in 2015
