Answer:

2.41 * n = y

Step-by-step explanation:

From the table, we can notice that the value;

y/n is a constant for each of the rows

this represents the individual costs of each of the books

So, we have it that;

7.23/3 = 4.82/2 = 9.64/4 = $2.41

So, the books have a unit cost of $2.41

Hence, by multiplying the number of books n by 2.41 we can get the cost y

So mathematically, we have the relation as;

2.41 * n = y

Calculate the force exerted on the blown dart. A dart weighing 0.0056kg is blown and travels 4.85m. The change in velocity for t

dlinn [17]

Answer:

0.15N

Step-by-step explanation:

Given data

Mass= 0.0056kg

distance= 4.85m

Velocity= 11.4m/s

The expression for the force is

F= mv^2/r

substitute

F= 0.0056* 11.4^2/4.85

F= 0.0056*129.96/4.85

F= 0.727776/4.85

F= 0.15N

Hence the force is 0.15N

Please help been stuck on this hw question ALLL DAYYYYYY

Rama09 [41]

Answer:

1 5/9

Step-by-step explanation:

9 1/3 can be rewritten as 28/3. The question is asking for you to divide 28/3 by 6. 6 is 6/1, so the expression is 28/3 divided by 6/1. You then do the reciprocal of 6/1 and the expression is $\frac{28}{3} * \frac{1}{6}$ . This gets you 28/18, which is simplified to 14/9 or 1 5/9. Hope this helps!

A three-bedroom house in North Augusta sold for $190,000. If housing prices are expected to increase 1.8% annually in that town,

Ivahew [28]

Answer:

we know that the initial price of the house is $190,000.

We also know that the expected increase is 1.8%, this means that the year zero we have no increase; the price is $190,000.

one year after we have an increase of the 1.8% (or 0.018 in decimal form), this means that the new price is:

$190,000 + $190,000*0.018 = $190,000*(1.018)

another year after, we have:

$190,000*(1.018)*(1.018) = $190,000*(1.018)^2

and etc

The function that models the price as a function of the years, represented as y, is:

P(y) = $190,000*(1.018)^y

If we want to know the price in 5 years, we need to replace y = 5 in the equation:

p(5) = $190,000*(1.018)^5 = $207,726.80

Step-by-step explanation:

hope this helps you

Use the remainder theorem to divide 5x^2+9x-2 by x+3. What is the remainder

marishachu [46]

Answer:

Step-by-step explanation:

Given

f(x)=5x^2+9x-2

Remainder theorem states that when f(x) is divided by x-a then the remainder can be calculated by calculating f(a).

Now Using the remainder theorem to divide 5x^2+9x-2 by x+3 to find the remainder:

f(x)=5x^2+9x-2

f(-3) = 5(-3)^2 +9(-3) -2

=5(9) - 27 -2

= 45-29

= 16 !

Antonio is in a bowling league. His goal is to score an average of at least 100 points per game. His scores so far are 105,95,97

Vilka [71]

The answer would be 11.
He’s playing 6 games to meet his goal which is 600. Adding 105+95+97+82+110 you’ll have 489 total points. You’ll then subtract 600-489 which will equal to 111.
