Not? Is t(n)=2⋅3n

Vera_Pavlovna [14]

Answer:

Step-by-step explanation: I am used to describing arithmetic sequences like this:

3,5,7,...3, comma, 5, comma, 7, comma, point, point, point

But there are other ways. In this lesson, we'll be learning two new ways to represent arithmetic sequences: recursive formulas and explicit formulas. Formulas give us instructions on how to find any term of a sequence.

To remain general, formulas use

nn to represent any term number and

(

)

a(n)a, left parenthesis, n, right parenthesis to represent the

n, start superscript, start text, t, h, end text, end superscript term of the sequence. For example, here are the first few terms of the arithmetic sequence 3, 5, 7, ...

The perimeter of an isosceles triangle is p = 2a + b. Find the numerical value of a if p = 10 and b = 3.

bagirrra123 [75]

P = 2a + b
10= 2a + 3
2a = 10-3
a = 7/2 = 3.5

Therefore, numerical value of a is 3.5

Using the functions presented in the example, how much can Cam expect to earn if he sells all the corn produced on 1.5 acres?

12345 [234]

Answer:

Cam expect to earn if he sells all the corn produced on 1.5 acres is $8725.

Step-by-step explanation:

Given : $C(a)=7500a-1500$ , $M(C)=0.9C- 50$ and $M(C(a))=6750a-1400$

To find : How much can Cam expect to earn if he sells all the corn produced on 1.5 acres?

Solution :

$C(a)=7500a-1500$

Substitute a=1.5,

$C(1.5)=7500(1.5)-1500$

$C(1.5)=11250-1500$

$C(1.5)=9750$

Now, taking function $M(C)=0.9C- 50$

Substitute C=9750,

$M(9750)=0.9(9750)- 50$

$M(9750)=8775- 50$

$M(9750)=8725$

Now, taking function $M(C(a))=6750a-1400$

Substitute a=1.5,

$M(C(1.5))=6750(1.5)-1400$

$M(C(1.5))=10125-1400$

$M(C(1.5))=8725$

Therefore, Cam expect to earn if he sells all the corn produced on 1.5 acres is $8725.

Four times a number minus twice another number is -8. The sum of the two number is 19.Find the numbers

grigory [225]

1. To solve this exercise, you must make a system of equations.

2. You have that four times a number minus twice another number is -8:

4x-2y=-8

3. And the sum of the two number is 19:

x+y=19

4. As you can see, you have two equations:

4x-2y=-8 (i)
x+y=19 (ii)

5. Let's clear the "x" from the equation (ii):

x=19-y

6. Now, you need to susbtitute x=19-y into the equation (i):

4x-2y=-8
4(19-y)-2y=-8
76-4y-2y=-8
76-6y=-8
-6y=-8-76
-6y=-84
y=-84/-6
y=14

7. You must susbstitute y=14 into the equation (ii) and clear "x":

x+y=19
x+14=19
x=19-14
x=5

The answer is: 5 and 14
