Answer:
Step-by-step explanation:
a1 = 3
d = -3
an = a1 + (n - 1)*d
an = a1 + (n - 1)*-3
Try it
Let n = 5
a5 = 3 + (5 - 1)*-3
a5 = 3 + 4*-3
a5 = 3 - 12
a5 = - 9 which is exactly what it should be.
The interesting one to try is n = 2
a2 = a1 + (2 - 1)*-3
a3 = 3 + 1(-3)
a3 = 3 - 3
a3 =0
Which is exactly what the second term is. It's interesting because you would never guess that 0 is what you get.
As an example, 534 can also can also be written as:
- five hundred thirty four
-500+30+4

Answer:
<h2>
y + 2 = ³/₄(x + 8)</h2>
Step-by-step explanation:
The point-slope form of the equation that describes the line with a slope of <em>m</em> and containing the point (x₀, y₀) is: y - y₀ = m(x - x₀)
m = ³/₄
(-8, -2) ⇒ x₀ = -8, y₀ = -2
Therefore:
y - (-2) = ³/₄(x - (-8))
y + 2 = ³/₄(x + 8)
Answer:
2.5722 .
_____________________________________________________ Explanation: _________________________________________________ log(base "
" of 19 = y ? ; Solve for "y" ;
__________________________________________________ ^ (y) = 19 ; Solve for "y" ?
__________________________________________________Take the "ln" (that is, "natural logarithm", of both sides:
__________________________________________________ ln [
^ (y) ] = ln 19 ;
__________________________________________________ y * ln
= ln 19 .
__________________________________________________ Use "3.1416" as an approximation for: "
" ;
__________________________________________________ y * ln (3.1416) = ln 19 ;
__________________________________________________ Divide EACH side of the equation by: " [ ln (3.1416) ]" ; to isolate "y" on one side of the equation; and to solve for "y"; (Use a calculator to do this) ;
_________________________________________________________ y * ln (3.1416) / [ ln (3.1416) ] = ln 19 / [ ln (3.1416) ] ;
________________________________________________________ y = ln 19 / [ ln (3.1416) ] ;
_______________________________________________________ y = 2.5721639670047041 ;
→ round to nearest 4 (FOUR) decimal places;
_______________________________________________________ → y =
