We know that

Appy this to the two known terms and find the first term and the common difference

Find the coomon difference

Find the first term

Now find the 43th term

Answer:

-98

Step-by-step explanation:

General form of an arithmetic sequence:

  [tex]a_n=a+(n-1)d[/tex]

where:

Given:

To find the 43rd term we need to construct an equation for the nth term.  To do this, find the first term and the common difference by substituting the given information into the general formula to create a system of equations that can be solved.

[tex]\begin{aligned} \underline{\textsf{Equation 1}}} \\ a_{21} & =-32 \\ \implies a+(20-1)d & = -32 \\a+20d & =-32 \end{aligned}[/tex]

[tex]\begin{aligned} \underline{\textsf{Equation 2}}} \\ a_{50} & =-119 \\ \implies a+(50-1)d & = -119 \\a+49d & =-119 \end{aligned}[/tex]

Subtract Equation 1 from Equation 2 to eliminate a:

[tex]\begin{array}{r l}a+49d & = -119\\- \quad a+20d & = -32\\\cline{1-2}29d & = -87\end{aligned}[/tex]

Solve for d:

[tex]\implies d=\dfrac{-87}{29}=-3[/tex]

Substitute the found value of d into one of the equations and solve for a:

[tex]\implies a + 20(-3)=-32[/tex]

[tex]\implies a=28[/tex]

Substitute the found values of a and d into the general formula to create an equation for the nth term:

[tex]\implies a_n=28+(n-1)(-3)[/tex]

[tex]\implies a_n=31-3n[/tex]

Finally, substitute n = 43 into the found formula to find the 43rd term of the sequence:

[tex]\implies a_{43}=31-3(43)=-98[/tex]

Answer:

The answer to 30*120 is 3,600

Answer:

30 times 120 equals 3600

Step-by-step explanation:

One thing that is really easy to use to multiply is a calculator (either online or a hand-held one). But here is how you can multiply without a calculator...

Set up an equation on a piece of paper like how it is shown right below...

  30

x 120

Then, times the last digit (so the zero) of the bottom number. (But it doesn't really matter what order you put them in). Then, times it by the last digit of the top number. So that would equal 0! So as shown below, you would put the answer like so...

  30

x 120

      0

Then, you do 0 (last digit of bottom number) times 3 (you keep going left of the top number's digits). So that would also equal 0.

   30

x 120

   00

     0

Then you add a zero below, since we are now moving on to the next number to the left of the last digit of the bottom number (hopefully this is making sense). Then you do the exact same thing.

   30

x 120

   00

 600

Now that we're done with that, we add two zeros this time, since we are in the hundreds now. So it is to the next number now! (1) And then we do the exact same thing again!

   30

x 120

   00

 600

3000

Alright, that's done! Now we add all those answers together (0+600+3000)

And that gives us our answer! 3600!

Hopefully that made sense! :)

[tex]\pi r^{2}[/tex]Answer:

You must know the radius but...

Step-by-step explanation:

The formula to find volume of a cylinder is: B*h

B= area of base

h=height

To find the area of the base you need to know the radius since the formula to find area of a circle is: [tex]\pi r^{2}[/tex]

Once you find the area of the base you just multiply it by the height

Answer:

t = 2

Step-by-step explanation:

using the rule of logarithms

given

[tex]log_{4}[/tex] (7t + 2) = 2 , then

7t + 2 = 4² = 16 ( subtract 2 from both sides )

7t = 14 ( divide both sides by 7 )

Answer:

280 in ^2

Step-by-step explanation:

Hi ok heres how I did this:

SA of rectangular prism: S = 2(lw + lh + wh)

SA of triangle top thing(whats it called???): Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area) = (S1 + S2+ S3)L + bh

So basically for the square part, the surface area is

2(4*4+4*12+4*12), or 224

For the triangle part, the surface area is

4+4+4, or 12*4+2*4, or 48+8, or  56

224+56=280

The thing is I don't know why it says round though. Theres a chance its incorrect if they want something with a decimal. Let me know.

x=2

The product of the two equation in which one is binomial equation another quadratic equation,  is 12a³+2a²+23a+18.

To multiply the two equation, each term of the first equation is multiples from the second term.

The first equation given in the problem is,

Answer:

f(8)= -16 + 6

Step-by-step explanation:

f(x) = -2x + 6(4-3)

f is a function. In this case, a function of variable x. So wherever x is written, swap it by the variable of a number which is 8.

The range for the given function is ~

Answer: 41.

Step-by-step explanation: To find the mean of a data set, you first need to add all the numbers together.  It should look like this:

28 + 40 + 53 + 39 + 45 = 205.

The next step is to divide 205 by how many numbers you have in the data set.  In this case, you have 5 numbers in the data set.  Your work should look like this:

205 / 5 = 41.

Therefore, the mean of the data set is 41.
