Answer:3/3
Step-by-step explanation:
x=3 and x 3
Distribute- 2n-6=24
Add 6 both sides- 2n=30
Divide by 2- n=15
Answer is n=15
Step-by-step explanation:
x=29
y=20
that's the answer
Answer:
x=-1 is a maximum vaue.
Step-by-step explanation:
To find the minimum and maximum values of the function f(x), we're going to derivate it:
f(x) = –5x^2 – 10x + 6 ⇒ f'(x) = -10x - 10
The points where f'(x) is zero, could be a maximum or a minimum. Then:
f'(x) = -10x - 10 = 0 ⇒ x=-1
Now, to know if x=-1 is a maximum or a minimum, we need to evaluate the original function for x when it tends to -1 from the right and from the left.
Therefore:
For x=-2:
f(x) = 6 (Positive)
For x=0:
f(x) = 6 (Positive)
For x=-1
f(x) = 11 (Positive)
Given that at x=-1, f(x) = 11, and then it goes down to 6 when x=0, we can say that it's a maximum.
Answer:
1064 ft.
Step-by-step explanation:
Start by sketching out a figure to represent the situation, it should look something like this:
(See picture)
(Figure definitely not drawn to scale)
The angle marked in red measures 4.3°, then we can use the law of sines to solve for the height of the Eiffel Tower (represented as the variable x):
Rounding gives 1064 ft.
