8x^3 + 2x^2 - 20x - 5

(8x^3 + 2x^2) + (-20x - 5)

2x^2 (4x + 1) + (-5) (4x+1)

(2x^2 - 5) (4x + 1)

Let months be x

[tex]\\ \sf\longmapsto 80+15x=29x[/tex]

[tex]\\ \sf\longmapsto 29x-15x=80[/tex]

[tex]\\ \sf\longmapsto 14x=80[/tex]

[tex]\\ \sf\longmapsto x\approx 6months[/tex]

Answer:

43  months in ymca including the $80 sign up fee is equal to 25 months in blink

Step-by-step explanation:

$725 divided by $29 =25 months

$ 725 - $80 sign up = $645 .

Now we divide this by $15.

$645 divided by 15= 43 months

Answer:

8 hours = 7,829 toy spinners

24 hours= x toy spinner

7829 / 24 x 8

2069 for one hour

Step-by-step explanation:

so your answer is this hope this helps good luck if it does not i am sorry

The number of toy spinners the machine make each hour is 2068.

Given that, the machine makes 7,829 toy spinners in 1 day.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Here,

8 hours = 7,829 toy spinners

24 hours= x toy spinner

Now, number of toys in one hour = 7829/(24×8)

= 2069.66

= 2069 per one hour

Therefore, the number of toy spinners the machine make each hour is 2069.

Answer:

 If there is a system of magnets being held in place, there is potential energy

Step-by-step explanation:

pretty sure you've seen this answer before but 8ts right so just go along with it ok bud?

Answer:

Okay

Magnets work because opposite poles are attracted to each other, this is how the objects move (depending on how the atoms and how to iron is, it could be much stronger or weaker)

If there is a system of magnets there is potential energy, when you let go of the magnets (or when they stick together) it converts the potential energy to kinetic energy because it moved.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Good job on creating a testable equation.

Maybe you need to know what to do with it.

If we can find a real solution or two, then the projectile will reach the 100 ft altitude. (I'm fairly certain it will given that high initial velocity)

If we cannot find a real solution, then the rocket will fail to reach the altitude goal.

-16t² + 80t + 4 = 100

we will want a zero on the right hand side, so subtract 100

-16t² + 80t - 96 = 0

we can simplify even further by dividing everything by -16

t² - 5t + 6 = 0

which can be factored

(t - 3)(t - 2) = 0

so either

t = 3 s

or

t = 2 s

So the projectile reaches the 100 ft level twice,

at two seconds after launch while rising and

at three seconds after launch while falling.

Lets see what happens when we set the goal a bit higher, say 108 ft

-16t² + 80t + 4 = 108

-16t² + 80t - 104= 0

-2t² + 10t - 13 = 0

not easily factored so let's use quadratic formula

t = (-10 ±√(10² - 4(-2)(-13))) / (2(-2)

t = (-10 ±√-4) / -4

As √-4 = 2i is an imaginary number, there are no real solutions and the projectile will not reach 108 ft.

Answer:

-b = 14

-n = 28

Step-by-step explanation:

For b

50/100=b/28 cross-multiply

1400= 100b divide both sides by hundred

-b = 14

For n

25/100= 7/n cross multiply

25n = 700 divide both sides by 25

-n = 28

Step-by-step explanation:

Well, according to this graph,

The greatest growth should be between the years 3 and 4. the reason is because if you count (under the students column) how many numbers are increasing between the numbers. In this case, the largest (increasing) number of students was between 25 and 33. (i counted 7)

So, the completed sentence should be:

(please note the parenthesis is the drop down.. I am unsure of the answer choices in the drop downs though so they might be differently worded. this is just what i have gathered.)

The greatest growth was between years (3) and (4). The growth between those years was about (7 students). In the last dropdown it may just be 7 but in word form.

Answer:

25%

Step-by-step explanation:

add both kinds of tickets first to get the total

24 early admission + 72 regular = 96 total tickets

then divide 24 early tickets by 96 total tickets to get the decimal, then multiply by 100 to get percent

[tex]\frac{24}{96} = 0.25 * 100 = 25[/tex]%

The critical value zα/2 that corresponds to a 83% confidence level is 1.37.

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]

Given that the confidence level (C) = 83% = 0.83

α = 1 - C = 0.17

α/2 = 0.17/2 = 0.085

The z score of α/2 corresponds with the z score of 0.415 (0.5 - 0.085) which is equal to 1.37
