The true statement about the graph of the function f(x) = x3 - 2x2 + 4x – 8 is (B) The function has 1 real zero that occurs 1 time.

The function of f(x) is represented as:

[tex]f(x)=x^3-2x^2+4x-8[/tex]

Differentiate the function f(x)

[tex]f'(x)=3x^2-4x+4[/tex]

Calculate the minimum value using:

[tex]x = -\frac b{2a}[/tex]

So, we have:

[tex]x = -\frac {-4}{2*3}[/tex]

[tex]x = \frac {2}{3}[/tex]

Substitute 2/3 in f'(x)

[tex]f'(2/3)=3*(2/3)^2-4(2/3)+4[/tex]

[tex]f'(2/3)=\frac 83[/tex]

The value of f'(2/3) is greater than 0.

This means that the function f(x) has 1 real zero, and it occurs once at point (2,0)

Hence, the true statement is (b)

This is a trick question. They eat 1/3 of the gallons given. Multiply

1/3 * 1/3 = 1/9 gallons or 0.111 gallons

Answer: Aye aye, cap'in

Step-by-step explanation:

So we start off with our base value, 1/3 gallons.

We are trying to find how many gallons we have eaten, so we do 1/3*1/3, since we need to find what is 1/3rd of that gallon.

For reference, if you wanted to find how much is left over, we multiply by 2/3 since 1-1/3 = 2/3, so there are 2/3 of the 1/3rd gallons left. Not important for solving this problem, but it might help you understand why we decided to multiply by 1/3.

1/3 * 1/3 = 1/9

Our answer is 1/9.

Answer:

21%

Answer:

33.22 square inches

Step-by-step explanation:

Diameter to Radius: [tex]\frac{1}{2}d = r[/tex]

Area of Circle: [tex]\pi r^2[/tex]

We are given the diameter of a pancake as 4.6 inches, so the radius is 2.3 inches. Next, we have to apply the area of circle formula with pi as 3.14 and the radius as 2.3

Next, since there's two pancakes, we double 16.6106.

Lastly, we round to the nearest hundredth.

Therefore, the answer is 33.22 square inches.

Answer:

28.26

Step-by-step explanation:

The circumference of a circle is equal to 2πr, where r is the radius. The radius is the distance from the center of the circle to a point on the outside of the circle.

To find the circumference you can plug in the known information and multiply. However, instead of using actual pi, we will use 3.14 because that is what the question says.

This means that the distance around the rug is 28.26 feet.

Answer:

Distance between Gas Station and House = 7.81 miles.

Step-by-step explanation:

The distance between the two locations is 7.81 miles

Given the point at (4,3) represents the location of her house, and the point at (10, 8) represents the location of the gas station.

The distance between the two locations will be determined using the formula

D [tex]=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute the given coordinate into the formula

[tex]D=\sqrt{(-6)^2+(-5)^2}\\D=\sqrt{(4-10)^2+(3-8)^2}\\D=\sqrt{36+25}\\ D=\sqrt{61}\\ D=7.81miles[/tex]

Hence the distance between the two locations is 7.81 miles

Answer: Triangle 4

The specific translation or shifting is "move 9 units to the right and 4 units down".

We can prove this by looking at something like point A(-10,2) and note how it moves to (-4,-2). Going from (-10,2) to (-4,-2) is exactly 9 right and 4 down.

In terms of x,y notation the translation rule is [tex](x,y) \to (x+9,y-4)[/tex]

The amount of mass after 5 minutes is 75.74 grams.

It is given that

The amount initially = 330grams

After every minute mass decays by 25.5%

The percentage is the value per hundred.

Amount after 1 min = 330-330*25.5/100 = 245.85grams

Amount after 2 min = 245.85-245.85*25.5/100 = 183.16grams

Amount after 3min = 183.16-183.16*25.5/100 = 136.45grams

Amount after 4 min = 136.45-136.45*25.5/100= 101.66grams

Amount after 5 min =101.66-101.66*25.5/100 = 75.74grams

Therefore, the amount of mass after 5 minutes is 75.74 grams.

Answer:

y = [tex]\frac{1}{2}[/tex] x

Step-by-step explanation:

the inscribed angle y is half the measure of the central angle x

y = [tex]\frac{1}{2}[/tex] x

Answer:

y = 2, 5, 8, 11, 14

Step-by-step explanation:

For this question, it's simply asking us to solve for y, at given values of x. So everytime we just need to substitute the given value for x and solve for y.

x + y = 8

When x = 6,

6 + y = 8

substract 6 from both sides:

-6 + 6 + y = 8 - 6

y = 2

When x = 3

3 + y = 8

y = 8 - 3

y = 5

When x = 0

0 + y = 8    --> 0 + y = y

y = 8

When x = - 3

- 3 + y = 8

y = 8 + 3

y = 11

When x = - 6

-6 + y = 8

y = 8 + 6

y = 14

Answer:

the ordered pair (12,3) is viable

Explanation:

These were my answer choices:

a. The ordered pair (–3, 7) is viable.

b. The ordered pair (0, 4) is viable.

c. The ordered pair (7, 0) is non-viable.

d. The ordered pair (12, 3) is viable.

I just took the test and d was correct:)

The factored form of the considered polynomial is [tex](x+3)(x+8)[/tex]

If the given quadratic expression is of the form

[tex]ax^2 + bx + c[/tex]

then its factored form is obtained by two numbers alpha( α ) and beta( β) such that:

[tex]b = \alpha + \beta \\ ac =\alpha \times \beta[/tex]

Then writing b in terms of alpha and beta would help us getting common factors out.

For the considered polynomial, we've got the quadratic expression as:

[tex]x^2 + 11x + 24[/tex]

Comparing this with [tex]ax^2 + bx + c[/tex], we get:

Therefore, we have : ac = c = 24

Two numbers whose multiplication gives 24 and and whose addition gives 11.

24 = [tex]2 \times 2 \times 2 \times 3[/tex]

If we take first three 2s, and 3, then:

[tex]24 = 8 \times 3 = (2 \times 2 \times 2) \times 3\\11 = 8 + 3 = (2 \times 2 \times 2) + 3[/tex]

Thus, we need to write 11 in the middle in terms of 8 and 3:

[tex]x^2 + 11x + 24 = x^2 + 8x + 3x + 24 = x(x+8) + 3(x+8) = (x+3)(x+8)[/tex]

Thus, the factored form of the considered polynomial is [tex](x+3)(x+8)[/tex]

We are given with a function y and need to find dy/dx or the first Derivative of y w.r.t.x , but let's recall

Now consider :

[tex]{:\implies \quad \sf y=e^{x}-\dfrac{1}{x}+log_{e}x}[/tex]

Differentiating both sides w.r.t.x

[tex]{:\implies \quad \sf \dfrac{d}{dx}(y)=\dfrac{d}{dx}\bigg\{e^{x}-\dfrac{1}{x}+log_{e}x\bigg\}}[/tex]

[tex]{:\implies \quad \sf \dfrac{dy}{dx}=\dfrac{d}{dx}(e^x)-\dfrac{d}{dx}\left(\dfrac{1}{x}\right)+\dfrac{d}{dx}(log_{e}x)}[/tex]

[tex]{:\implies \quad \sf \dfrac{dy}{dx}=e^{x}-\dfrac{d}{dx}(x^{-1})+\dfrac{1}{x}}[/tex]

[tex]{:\implies \quad \sf \dfrac{dy}{dx}=e^{x}-(-1)(x)^{-1-1}+\dfrac{1}{x}}[/tex]

[tex]{:\implies \quad \sf \dfrac{dy}{dx}=e^{x}+(x)^{-2}+\dfrac{1}{x}}[/tex]

[tex]{:\implies \quad \sf \dfrac{dy}{dx}=e^{x}+\dfrac{1}{x^{2}}+\dfrac{1}{x}}[/tex]
