Answer:
d = -1/3, 0
Step-by-step explanation:
Subtract the constant on the left, take the square root, and solve from there.
(6d +1)^2 + 12 = 13 . . . . given
(6d +1)^2 = 1 . . . . . . . . . .subtract 12
6d +1 = ±√1 . . . . . . . . . . take the square root
6d = -1 ±1 . . . . . . . . . . . .subtract 1
d = (-1 ±1)/6 . . . . . . . . . . divide by 6
d = -1/3, 0
_____
Using a graphing calculator, it is often convenient to write the function so the solutions are at x-intercepts. Here, we can do that by subtracting 13 from both sides:
f(x) = (6x+1)^ +12 -13
We want to solve this for f(x)=0. The solutions are -1/3 and 0, as above.
Answer:
The rate of change is ft^(2)/min
Step-by-step explanation:
The area of a circle is given by the following equation:
To solve this question, we have to realize the implicit differentiation in function of t. We have two variables, A and r. So
We have that:
.
We want to find
So
Since the area is in square feet, the rate of change is in ft^(2)/min.
So the rate of change is ft^(2)/min
Subtract the smaller amount ($23.04) from the larger ($29.40), and then divide the difference by 12 pounds:
$6.36
-------- = $0.53 / lb
12 lb
Answer:
Step-by-step explanation:
10. To solve for this, use the formula: 180*(n-2)
So, 180(n-2) = 2,340
Once n is solved for, that is the number of sides
11. Use the formula:
[180*(n-2)]/n
(n represents the number of sides)
12. Think of the sum of all interior angles in a quadrilateral
