Next value 4 D 7 G 10 J 13
ValentinkaMS [17]
Hello,
 
In this pattern you can notice that  the numbers and letters alternate, 1 by 1. Also, from each number to the next, 3 is added. (4 + 3 = 7, 7 + 3 =10, 10 + 3 = 13). For the letters, it goes in alphabetical order with two letters being skipped between each letter. (D, G, J). 

Based on the number letter pattern, the last value is a number indicating a letter is next. Now, we just follow the same "skip two" letters pattern to get from J to M.

I believe M is the answer.
Hope this helps!

If sin θ = 2 over 7 and tan θ > 0, what is the value of cos θ?
sergey [27]
Sin θ = 2 / 7
tan θ > 0
cos θ = ?

sin θ = opposite / hypotenuse
tan θ = opposite / adjacent
cos θ = adjacent / hypotenuse

short leg = opposite = 2
hypotenuse = 7
long leg = adjacent = ?

adjacent = √(7² - 2²)
adjacent = √(49 - 4)
adjacent = √45
adjacent = √9 * 5
adjacent = 3 √5

cos θ = adjacent / hypotenuse
cos θ = 3√5 / 7

The accompanying table shows the number of bacteria present in a certain culture over a 4 hour period, where x is the time, in h
Vlad [161]

Answer:

Step-by-step explanation:

I really hope you know how to use your calculator to find regression equations, because in this forum it is impossible to teach you how to do that. I ran the data through my calculator and got the exponential equation as

y=1963.56(1.14)^x which means at 4 hours, we started with 1963 bacteria and it is growing at a rate of 114% each hour. Since we started out with an x value of 0, and that value represents the number of bacteria after 4 hours, then time 0 is 4 hours, which means that time 12 is 16 hours. We replace the x in the equation with a 12 and do the math:

y=1963.56(1.14)^{12 which gives us, in the end,

y = 9460
