UkoKoshka [18]

<h2>Answer: 1</h2>

Step-by-step explanation:

Just plug in -2 anywhere you see an <u>a</u>

$f(a)=2a^3+3a^2+5\\f(-2)=2(-2)^3+3(-2)^2+5\\f(-2)=2(-8)+12+5\\f(-2)=-16+12+5\\f(-2)=1$

Enter an equation in point-slope form for the line.<br> Slope is 1/6 and (−7, 1) is on the line.

Andrej [43]

Point-slope form: y - y1 = m(x - x1)

(x1, y1) = a coordinate

m = slope

Now, substitute with the given information.

y - 1 = 1/6(x + 7)

Hope This Helped! Good Luck!

Use math notation to describe the following sequence: <br> 1, -1, 1, -1,...

Veseljchak [2.6K]

Answer:

The math notation to the given sequence is $a_n=(-1)^{n+1}$ for n=1,2,3,... is verified and it is true

Step-by-step explanation:

Given sequence is 1,-1,1,-1,...

Let $a_1=-1,a_2=1,a_3=-1,a_4=-1,...$

To find the math notation for the given sequence :

$a_n=(-1)^{n+1}$ for n=1,2,3,... verify that it is true or not

Put n=1 in the above equation we get

$a_1=(-1)^{1+1}$

$=(-1)^2$

Therefore $a_1=1$

Put n=2 in the $a_n=(-1)^{n+1}$ equation we get

$a_2=(-1)^{2+1}$

$=(-1)^3$

Therefore $a_2=-1$

Put n=3 in the $a_n=(-1)^{n+1}$ equation we get

$a_3=(-1)^{3+1}$

$=(-1)^4$

Therefore $a_3=1$

and so on

Therefore the math notation to the given sequence is $a_n=(-1)^{n+1}$ for n=1,2,3,... is verified and it is true
