We have that we are given 4 formulas for the products; there are split in 2, one for each company and they are also split in 2 on whether they are predictions or date. We need to substitute in x=4 days for all of them to calculate the value after 4 days after the launch (initial day counts for x=0).
For company A, the actual average downloads per day were: for x=0 (day 1), x=1, x=2, x=3, x-4:
f(0)=450, f(1)=562.5, f(2)=703, f(3)=879, f(4)=1099
To find the average download per days, we have that we divide the final downloads f(4) by the number of days, 4. This yields 275 downloads per day.
For the prediction formula f(x)=400*1.5^x, if we substitute x=4 we get 2025 downloads. This yields on average 506 downloads per day.
Thus, the difference is 231 downloads per day and we have a decrease in the data (from predicted to actual downloads).

For company B, the same procedure for the actual data yields: g(4)=2621 downloads after 4 days, hence 655 downloads on average; the prediction data yields  500*1.4^4=1921 and on average 480 downloads per day; the difference is around 175 (174 due to rounding errors) downloads per day and it is still a decrease (predictions are lower).

Thus, company B was more accurate.

The weight, w, of a spring in pounds is given by 0.9 times the square root of the energy, E, stored by the spring in joules. If
frutty [35]
For this case we have the following equation:
 w = 0.9* \sqrt{E}
 Where,
 w: The weight of a spring in pounds
 E: the energy stored by the spring in joules.
 Substituting values we have:
 w = 0.9* \sqrt{12}
 Making the corresponding calculation:
 w=3.12
 Answer:
 
the approximate weight of the spring in pounds is:
 
w=3.12

At the end of a recent WNBA regular season, the Phoenix murmur had 12 more victories than losses. The number of victories they h
Hoochie [10]

Answer:

34 games


Step-by-step explanation:

let the number of losses be  l

let the number of victories be  v


<u>the Phoenix murmur had 12 more victories than losses:</u>

v=l+12

<u>The number of victories they had was one more than two times the number of losses:</u>

v=2l+1


<em>We have 2 expressions for v, equating these 2, we can solve for l:</em>

l+12=2l+1\\12-1=2l-l\\11=l

So 11 games, they lost.

Using this value, we can plug into the 1st equation to solve for v:

v=l+12\\v=11+12\\v=23

So 23 games, they won.


Given that no draws, they played a total of 23 + 11 = 34 games this season

Solve eight and two fourths minus three and one third
soldier1979 [14.2K]

Answer:

5 1/6

Step-by-step explanation:

Rewriting our equation with parts separated

=8+2/4−3−1/3

Solving the whole number parts

8−3=5

Solving the fraction parts

2/4−1/3=?

Find the LCD of 2/4 and 1/3 and rewrite to solve with the equivalent fractions.

LCD = 12

6/12−4/12=2/12

Reducing the fraction part, 2/12,

2/12=1/6

Combining the whole and fraction parts

5+1/6=5 1/6

Calculate the missing angle and give a reason for your answer
Vanyuwa [196]

Step-by-step explanation:

the triangle is an isosceles triangle hence the base angles are equal

sum of angles in a triangle is 180°, therefore, the top angle =180-(62+62)

the top angle =56°

h°= the top angle because alternate angles are equal

hence, h=56°
