Answer:
v(t) = 6t^2 +5
Step-by-step explanation:
Velocity is the derivative of position. The derivative of a sum is the sum of the derivatives of its terms. The power rule for derivatives is ...
(d/dx)(x^n) = n·x^(n-1)
So, the derivative of d(t) is ...
v(t) = 2(3t^2) +5(1t^0)
v(t) = 6t^2 +5 . . . . matches choice C
Answer:
Should be B
Step-by-step explanation:
I believe you just move the point that lines converge down 8 and to the right 3. Then you multiply the x-value by -1.
Answer:
2x² + 12x + 10
Step-by-step explanation:
Area of a rectangle = width x length
Therefore,
Area = (x + 1)(2x + 10)
Expand the brackets: 2x² + 10x + 2x + 10
Combine like terms: 2x² + 12x + 10
A quadratic expression is an expression with the variable with the highest power of 2
