I personally think it is <span>f(t) = 17.5 sin (π/4)(-t+6) + 17.5 </span>
6 because if you multiply (3/5)2 you get 6
To make x^2 + 2x a perfect square we need to add the term { 2 / (2*1) }^2
which equals 1.
Add 1 to both sides: x^2 + 2x = 8
add 1 to both sides: x^2 + 2x + 1 = 8 + 1 (x + 1)^2 = 9
Take square root on both sides: x + 1 = +/- 3 x = +3 - 1 or x = -3 - 1 x = 2 or x = -4
Answer:
he forgot the A
Step-by-step explanation:
:)
Slope formula : (y2 - y1) / (x2 - x1)
(2,-2)....x1 = 2 and y1 = -2
(4,1)...x2 = 4 and y2 = 1
now we sub into the slope formula and solve for the slope
slope = (1 - (-2) / (4 - 2) = (1 + 2) / 2 = 3/2
now we use y = mx + b
slope(m) = 3/2
use either of ur points....(4,1)...x = 4 and y = 1
now sub into y = mx + b formula and find b, the y int
1 = 3/2(4) + b
1 = 6 + b
1 - 6 = b
-5 = b
so ur equation is : y = 3/2x - 5 <==
