It’s referring to the lines in the text, so for each one read through the parts it says to and cite evidence for each question

Hope this helps :)

If P= Poert, fund the time it takes for P to go from Po to 2P. Give your answer in terms of In and r

Angelina_Jolie [31]

I think the formula is: P = P₀. e^(rt)

When P = 2P₀, the formula becomes 2P₀ =P₀.e^(rt)

Simplify by P₀, 2=e^(rt)

ln(2) = lne^(rt)

ln2 = rt.lne or lne =1 then ln2 = rt

Complete the factorization of 3x ^ 2 - 10x + 8 3x^ 2 -10x+8=(x- Box x-4)

aniked [119]

Answer:

$3x^2-10x+8=(x-x_1)(x-x_2)=(x-2)(x-\frac{4}{3})$

Step-by-step explanation:

The general form of a quadratic polynomial is given by:

$ax^2+bx+c$ (1)

You have the following polynomial:

$3x^2-10x+8$ (2)

In order to complete the factorization you can use the quadratic formula, to obtain the roost of the polynomial. The quadratic formula is given by:

$x_{1,2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$ (3)

By comparing the equation (1) with the equation (2) you obtain:

a = 3

b = -10

c = 8

Then, you replace these values in the equation (3):

$x_{1,2}=\frac{-(-10)\pm \sqrt{(-10)^2-4(3)(8)}}{2(3)}\\\\x_{1,2}=\frac{10\pm2}{6}\\\\x_1=2\\\\x_2=\frac{4}{3}$

Then, the factorization of the polynomial is:

$3x^2-10x+8=(x-x_1)(x-x_2)=(x-2)(x-\frac{4}{3})$

Chris wanta to enclose his circular vegetable garden with fencing to keep rabbits from eating his vegetables. If the diameter of

Stells [14]

The circumference of a circle of diameter d is given by

... C = π·d

Chris will need π·(18 ft) ≈ 56.55 ft of fence. S/he will need to buy 57 ft of fence.

_____

Whether you use 57 because 56.55 rounds up to that, or because 56.55 is needed and 56 would be too short, doesn't really matter in this case. I tend to choose the latter reason.

Please help ASAP!!

Sure, let me help you on this one!

Linear functions are written in the following format.

$y=mx +b$

Let's break this up! (Helpful image attached)

Now, it should be easy for you what to place where.

As we can see on the graph, slope of this graph is 1/3, meaning that for every 3 units it goes on the run, it goes 1 unit upwards on the rise.

We can also see y-intercept coming through -4, so let's mark it as well.

Let's write the final answer!

$y=1/3x-4$
