1st term = n
2nd term = n+1
3rd term = n+2
4th term = n+3

The fifth term in the sequence would be n + 4.

For the fifth term in the sequence a = 3(n+4) - 2.

This should get you started.

This means that the nth term in the sequence is equal to 3n-2. For example, if n was 7 then the term would be 3*7-2=19. This means that the fifth term would be (3*5)-2, which is 13.

Find a. Round to the nearest tenth:
Ulleksa [173]

Step-by-step explanation:

In the following triangle, a= ? , b= 2cm.

m<B= 105° , m<C = 15° ,m< A =?

Now, we know that sum of the interior angles of the triangle = 180°

m<B+m<C +m< A =180°

105°+15°+m< A=180°

m< A= 180- 120° = 60°

\frac{ \sin( A) }{a}  =  \frac{ \sin(B) }{b}

\frac{ \sin(60) }{a}  =  \frac{ \sin(105) }{2}

a =  \frac{ \sin(60) }{ \sin(105) }  \times 2

a = 1.79

a = 1.8

Describe a real life multiplication situation for which an estimate makes sense?
Tamiku [17]
There were 3  friends. Each of them bought 6 packs of candy. Each pack had 18 pieces of candy. How much candy did they have in total? . 

3 × 6 = 18

18 × 18 = 324

SO, they had 324 pieces of candy in total.

Hope I helped:P

If f(x)=2x^3-x+c and f(2)=10 then what's the value of c?
Goshia [24]

Answer:

c = -4

Step-by-step explanation:

If f(x) = 2x^3 - x + c and f(2) = 10, plug in 2 for the x values in the function and make the function output 10.

10 = 2(2^3) - 2 + c    Now, we only have to deal with one variable, that is c.

10 = 2(8) - 2 + c

10 = 16 - 2 + c

10 = 14 + c

-4 = c    After simplifying, we get that c is -4.

To check this, plug in 2 for x, and -4 for c in the function. If the function produces 10 as the result, the halleluja!

f(2) = 2(2^3) - 2 - 4

f(2) = 2(8) - 2 - 4

f(2) = 16 - 2 - 4

f(2) = 10
