Answer:

Which recursive formula can be used to generate the sequence below, where f(1) = 3 and n ≥ 1?

3, –6, 12, –24, 48, …

f (n + 1) = –3 f(n )

f (n + 1) = 3 f(n )

f (n + 1) = –2 f(n )

f (n + 1) = 2 f(n)

Please help me im not good at maths :(((

Answer:

A) 11% B) 60

Step-by-step explanation:

(for A) if you add all the "Frequency" it adds up to 100, so we don't need to do any maths for that because we already have our 100% right there. So less maths to do because if that right there is already the whole, then the frequency of it is the % out of 100%

(for B) If you take your calculator and do 12 x 500, you get 6,000, press the "%" button and it gives you the percent of what that probability of getting 6 after rolling 500 times with its sent frequency

(took me a minute to learn this this for you... by that i mean i messed around with my calculator for like 3 minutes) Hope this is right.

Decide, without calculation, if each of the integrals below are positive, negative, or zero. Let D be the region inside the unit
Schach [20]

The integrals over B and T will be positive. Keeping y fixed, xe^x is strictly increasing over D as x increases, so the integrals over x (i.e. the bottom/top left quadrants of D) is negative but the integrals over x>0 are *more* positive.

The integrals over R and L are zero. If we take f(x,y)=xe^x, then f(x,-y)=f(x,y), which is to say f is symmetric across the x-axis. For the same reason, the integral over all of D is also zero.

Solve the following equation. x/3 - 4 = 10
erma4kov [3.2K]

Answer: x=42


Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

- Solve for x.

- Add 10 and 4.

- Multiply the sum of 10 and 4 by 3. You must move it from the left member to the right member. Then, if  3 is dividing x, this will multiply the sum of 10 and 4. So, you have:

x/3=10+4\\x/3=14\\x=42

Therefore, you obtain that the value of x is 42
