2. A line contains the points

Mathematics
1 answer:
V125BC [204]2 years ago
4 0

Answer:

B

Step-by-step explanation:

equation of a line is in the form of y=mx+b where m is the slope and b is the y intercept

slope: -1-2/0-4 = 3/4

y intercept is when x is 0, so y intercept is -1

therefore the equation of this line is y=3/4x-1

Find the derivative of F(x)=-x^4+4x^3+ 70 for 0<=x<=3
timofeeve [1]

Answer:

  -4x^3 +12x^2 for 0 < x < 3

Step-by-step explanation:

The power rule is appropriate:

  (d/dx)x^n = n·x^(n-1)

This is applied to each of the terms.

  F'(x) = -(4·x^3) +4(3x^2) +0

  F'(x) = -4x^3 +12x^2 . . . . for 0 < x < 3

__

The derivative is not defined at the endpoints of the interval, so F'(x) is only defined on (0, 3), not [0, 3].

Z = 44i+ 23.3<br> What is the real part of z?<br> What is the imaginary part of z?
lord [1]

Answer:

  • real: 23.3
  • imaginary: 44

Step-by-step explanation:

The real part does not have i as a multiplier. It is 23.3.

The imaginary part* is the coefficient of i: 44.

_____

* There is some disagreement as to whether the imaginary part includes i or not. One source says the imaginary part is the part that has i as a factor (44i). Another source says the imaginary part is the real number that multiplies i (44). Above, we have used the latter definition. Please consult your curriculum materials for the definition you should use.
