b. 
c. 
d. 
Step-by-step explanation:
a) xy' -4y = 2 x^6

b) y' - 5y = 4e^7x

c) dy/dx + 2y = 2/(1+e^4x)

d) 1/2 di/dt + i = 4cos(3t)

Identify and calculate formulas and examples...
Hope this helps ;)
Answer:
Its the second choice.
Step-by-step explanation:
g(x) = (x - 3)^2 + 9
The -3 in the parentheses moves the graph of x^2 3 units to the right.
The + 9 moves it upwards 9 units.
Answer:
Step-by-step explanation:
√-80
Answer:
⇒ The given quadratic equation is x2−kx+9=0, comparing it with ax2+bx+c=0
∴ We get, a=1b=−k,c=9
⇒ It is given that roots are real and distinct.
∴ b2−4ac>0
⇒ (−k)2−4(1)(9)>0
⇒ k2−36>0
⇒ k2>36
⇒ k>6 or k<−6
∴ We can see values of k given in question are correct.
