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)

Step-by-step explanation:

this is D reflexive property of SSS

3. Any geometric figure compared to itself is congruent to itself so this is why:

4. Since we have a parallelogram, therefore we can say:

Both triangles ABC and CDA satisfy the side to side to side congruence, since their 3 sides are congruent.

So, It's D.

Slope intercept form of a linear equation:  y = mx + b

(where m is the slope and b is the y-intercept)

Given:

[tex]\mathsf{slope=\dfrac{21-11}{6-2}=2.5}[/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:

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:No solution

Step-by-step explanation:

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

I hope this makes sense :)

Answer:

y=-x+4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(2-3)/(2-1)

m=-1/1

m=-1

y-y1=m(x-x1)

y-3=-1(x-1)

y-3=-x+1

y=-x+1+3

The range of f(x) is y> 0 and the y-intercept is (0, 1). Therefore, options B, D and E are the correct answers.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given function is f(x)=(3/5)ˣ.

Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain: (−∞,∞),{x|x∈R}

Range: (0,∞),{y|y>0}

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.

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]
