Grouping,
looking at the coefficients (2,-7,-4, and 14)
you notice that 2,-4, and 14 are all factors of 2,
however you also notice that -7 and 14 arefactors of 7, so you want to group the terms containing -7 and 14 up (and 2 and -4 together)

so rearranging stuff
2x^3 -4x -7x^2+14

grouping
(2x^3-4x) + (-7x^2+14)

factoring stuff, (reverse distribution process)
notice you can factor out a 2x from the first group, and a -7 from the 2nd group, hence you will get

2x(x^2-2) -7(x^2-2)

you can factor out the (x^2-2) from both terms, hence you are left with

(2x-7)(x^2-2)

Can someone answer the blank ones please!!!

The equation is $155p+225f=5050$ .

If p = 17, f = 13. This value is a reasonable value in this context.

If f = 28, p = -10. This value is not reasonable in this context.

Step-by-step explanation:

Step 1:

$155p+225f=5050$ ,

where p is the part-time memberships and f is the number of full-time memberships.

Kiri needs to make $5,050 a month from this rented space.

Each part-time membership costs $155 and each full-time membership costs $225.

Step 2:

We need to calculate the value of f when p = 17,

Substituting the value, p = 17 in the equation, we get;

$125(17)+225f=5050$ , $225f=5050-125(17),$

$225f=2925, f = \frac{2925}{225}, f =13.$

The value of f = 13 and p = 17. This is a reasonable value in this context.

Step 3:

We need to calculate the value of p when f = 28,

Substituting the value, f = 28 in the equation, we get;

$125p+225(28)=5050$ , $125p=5050-225(28)$

$125p=-1250, p = \frac{-1250}{125}, p=-10.$

The value of f = 28 and p = -10. This is not a reasonable value in this context. as the values of f and p cannot be negative for this given equation.

a quantity with an initial value of 5900 decays exponentially at a rate of 0.85% every 7 years. what is the value of the quantit

laila [671]

The value of the quantity after 99 months is 5228.58.

Given that, an initial value = 5900, rate of decay = 0.85% and time period = 7 years.

<h3>What is the exponential decay?</h3>

The quantity decreases slowly after which the rate of change and the rate of growth decreases over a period of time rapidly. This decrease in growth is calculated by using the exponential decay formula.

The exponential decay formula formula is $Amount=Initial\ value(1-\frac{r}{100} )^{\frac{t}{n} }$

Here, the value $=5900(1-\frac{0.85}{100} )^{\frac{99}{7} }$

= 5900× $(0.9915)^{14.14}$

= 5900×0.8862

= 5228.58

Therefore, the value of the quantity after 99 months is 5228.58.
