Answer:
The derivative of the function is 42.
Step-by-step explanation:
The derivative of an addition/subtraction of terms is the addition/subtraction of the derivatives of these terms.
The derivative of a constant is 0. The derivative of 3 is 0, for example.
The derivative of is
. The derivative of 42x is 42, for example.
So, in this question, we have that:
h(x) = 42x-3
h'(x) = 42
So the derivative of the function is 42.
<h2>40 % of coins are pennies.</h2>
Step-by-step explanation:
Total number of coins = 600
Total number of pennies = 240
40 % of coins are pennies.
Since, Jesse is building a spice rack.
The total length of wood = 90 centimeters
He cuts the board into three parts.
The length of the first part = 23.5 cm
So, remaining length of the board = = 66.5 cm
Now, he cuts the second part.
The length of the second part = 33.3 cm
So, now remaining part of the board = = 33.2 cm
Now, he cuts the third part of the board.
The length of the third part = 19.45 cm
Now, the remaining part of the board = = 13.75 cm
So, the length of the original board after cutting the three parts = 13.75 cm
So, Option A is the correct answer.
