Answer:

Choice C

Step-by-step explanation:

f: initial value of 200 decreasing at a rate of 4%

g: initial value of 40 increasing at a rate of 8%

f is decreasing so it must go down starting at 200

That eliminates a and d

g is increasing and starts at 40 That eliminates a

We must look at b and c

g is increasing faster than f is decreasing

Choice C

Answer:

Step-by-step explanation:

f is decreasing so it must go down starting at 200

So options A and D are incorrect

Let's check out options B and C

g is increasing faster than f is decreasing

So B is incorrect

So that leaves you with option C, which is correct.

Hope this helped!

Using an arithmetic sequence, it is found that:

i) They collected 300 bottles on June 25th.

ii) The day was July 18th.

<h3>What is an arithmetic sequence?</h3>

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

$a_n = a_1 + (n - 1)d$

In which $a_1$ is the first term.

In this problem, the sequence is: {417 ,404 ,391, .........}, hence the first term is $a_1 = 417$ , the common difference is d = -13, and the equation is:

$a_n = 417 - 13(n - 1)$

Item i)

They started on June 15th, hence June 25th is the 10th day, thus:

$a_{10} = 417 - 13(9) = 300$

They collected 300 bottles on June 25th.

Item ii)

This is n days after June 15th, for which $a_n = 1$ , hence:

$a_n = 417 - 13(n - 1)$

$1 = 430 - 13n$

$13n = 429$

$n = 33$

33 days after June 15th is July 18th.

A farmer owns about 960 acres of land. If his farm is square, what would be the length of each side in miles, to the nearest ten

OLEGan [10]

It is given in the question that

A farmer owns about 960 acres of land. If his farm is square.

First we convert acres to miles square, and the conversion expression is

$1 acre=0.0015625 mi^2$

Therefore,

$960acres=960*0.0015625=1.5 mi^2$

Let the side length of the square be x miles .

And the formula of area of square is

$Area=side^2
\\
1.5=side^2
\\
side= \sqrt{1.5}=1.2 miles$

which statements are true about the graph of the function f(x) = 6x – 4 x2? check all that apply. the vertex form of the functio

Brut [27]

Answer:

The vertex of the function is the point $(-3,-13)$

The graph increase over the interval--------> (-3,∞)

Step-by-step explanation:

we have

$f(x)=6x-4+x^{2}$

1) Convert to vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$f(x)+4=x^{2}+6x$

Complete the square. Remember to balance the equation by adding the same constants to each side

$f(x)+4+9=x^{2}+6x+9$

$f(x)+13=x^{2}+6x+9$

Rewrite as perfect squares

$f(x)+13=(x+3)^{2}$

$f(x)=(x+3)^{2}-13$ -----> function in vertex form

2) Find the vertex

The vertex of the function is the point $(-3,-13)$

3) Find the axis of symmetry

we know that

In a vertical parabola, the axis of symmetry is equal to the x-coordinate of the vertex

The x-coordinate of the vertex in this problem is equal to $x=-3$

therefore

the equation of the axis of symmetry is $x=-3$

4) Find the increase-decrease intervals

The graph increase over the interval--------> (-3,∞)

The graph decrease over the interval--------> (-∞,-3)

see the attached figure to better understand the problem

5) Find the x-intercepts of the function

we know that

the x-intercepts are the values of x when the value of the function is equal to zero

In this problem the x-intercepts are

$(-6.61,0)$ and $(0.61,0)$

The function cross the x-axis twice

see the attached figure
