We are given with the expression y<span> = b cos t + t2 sin t and is asked to differentiate the function in terms of t. Based in the power law and law of products, we apply these to the given expresssion. the derivative is y' = -b sin t + t^2 * (cos t) + sin t * 2t. This is equal to </span>y' = sin t (-b +2t) + t^2 cos t.
Answer:
6 3/4
Step-by-step explanation:
multiply using keep change flip
1. solve for X and y using both equations to find the point they cross in
−x − y = −5
y = x + 1
Plug in y into first equation
-x-(x+1)=-5
-x-x-1=-5
-2x-1=-5
+1 both sides
-2x=-4
÷-2 both sides
x=2 solve for y
y=2+1
y=3
(2,3)
2. you can set them equal to each other so 2x+4=3x+1
Answer:
$14.50
Step-by-step explanation:
6 x $2.50 = $15.00
3 x $0.50 = $1.50
$15.00 + $1.50 = $16.50
$16.50 - $2.00 = $14.50
You cannot find x.
Because both phrases are to the power of 0, we know that it is essentially 1*1
So:
(3x - 8)^0 (4x - 23)^0 = 1
