Answer:
(-pi, 0)
Step-by-step explanation:
From the graph, we have 3 stationary point; the first one at x = 0, the second one at x = 1 and the last one at x = 2.
The function is increasing at two intervals.
The first increase is between x = -1 and x = 0.
The second increase is between x = 1 and x = 2.
From the choices give the interval that represent increase is (-pi, 0)
Answer:
X=20
Step-by-step explanation:
Answer:
(5+x)8
Step-by-step explanation:
Yes, 4\6 is greater than 6\10 because if you change them they will have a common denominator.
<span>Simplifying
49x^2 + -9 = 0
Reorder the terms:
-9 + 49x^2 = 0
Solving
-9 + 49x^2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9' to each side of the equation.
-9 + 9 + 49x^2 = 0 + 9
Combine like terms: -9 + 9 = 0
0 + 49x^2 = 0 + 9
49x^2 = 0 + 9
Combine like terms: 0 + 9 = 9
49x^2 = 9
Divide each side by '49'.
x^2 = 0.1836734694
Simplifying
x^2 = 0.1836734694
Take the square root of each side:
x = {-0.428571429, 0.428571429}
hope this helps!!</span>
