Answer: there are 4 solutions
x = -2
x = -1/2 = -0.500
x =(3-√5)/2= 0.382
x =(3+√5)/2= 2.618
Step-by-step explanation:
Answer:
B = j + H
Step-by-step explanation:
Given:
j = - H + B
Solve the equation for B
j = - H + B
Add H to both sides of the equation
j + H = - H + B + H
j + H = B
B = j + H
Answer:
X=35
Step-by-step explanation:
simplify 7/9
x/45-7/9=0
simplify x/45
x - (7 • 5)/45= x - 35/45
x-35/45=0
add 35 to both sides
x=35
I tried it's hard to write it all out on here i just to give u the best sorry :)
Answer:
a) dy/dx = 4/(2y+1)^2.
(b) y = 4/9 x - 14/9
(c) d2y/dx2 = -64/243
Step-by-step explanation:
You have the following equation
(1)
(a) You first derivative implicitly the equation (1) respect to x:
next, you solve the last result for dy/dx:
(2)
(b) The equation for the tangent line is given by:
(3)
with yo = -2 and xo = -1
To find the slope m you use the result of the equation (2), because dy/dx evaluated in (-1,-2) is the slope at such point:
m =
Hence, by replacing in the equation (3) you obtain:
hence, the equation for the tangent line is y = 4/9 x - 14/9
(c) To find d2y/dx2 you derivative the result obtain in the equation (2):
(4)
the second derivative for the point (-1,-2) is obtained by replacing y=-2 and dy/dx=m=4/9 in the equation (4):
hence, d2y/dx2 evaluated in (-1,-2) is -64/243
