Seems to be an arythmetic sequence
common difference is 3 (increases by 3 each time)
an=a1+d(n-1)
d=3
a1=8
an=8+3(n-1)
an=8+3n-3
an=3n+5
Answer:
Its b
Step-by-step explanation:
490 please trust me
Using the formula for slope, we can find out that
So -105 is the slope, and because she bought her laptop at $1160, the y-intercept is 1160. This means that the equation is V(t)=-105t+1160.
Answer:
tan cox³ / 5s
Replace ^-1 with ^(-1)
Replace x3 with x³
<h3>Step 1</h3>
Simplify
x³ / 5
Use equation to solve
tan • ((co • (s-1)) • x³ / 5)
<h3>Step 2</h3>
Take the previous equation and format it in a simpler form
tan • ((co • (s-1)) • x³ / 5) ⇒ tan • cox³ / 5s
<h3>Result</h3>
tan cox³ / 5s
To find an inverse matrix you first have to find the determinant and then put the absolute value of it under a 1. That's what is sitting outside in front of all those matrices. What you have to do now is multiply that determinant by what I teach to my students as the "mixed up matrix". They always remember from that. Change the position of the terms on the major axis (here they are a and d), and then switch the signs on the other 2 terms. Our inverse matrix then is
