Answer:
3,400,007
Step-by-step explanation:
three million= 3,000,000
four hundred thousand= 400,000
seven= 7
so:
three million, four hundred thousand, seven= 3,400,007
The measure of the angle <u>x = 90°</u>
<u>Theorem Of Tangent</u>:-
A radius is obtained by joining the centre and the point of tangency. The <u>tangent at a point on a circle is at right angles to this radius</u>.

Hope it helps you:)
Have a nice day..
Critical points: (Maximum, minimum, and inflection points) have a slope = 0
The derivative gives the slope, take the derivative set it equal to zero
<span>f(x) = x^5 -10x^3 + 9x
derivative:
f'(x) = 5x^4 - 30x^2 + 9
0 = 5x^4 - 30x^2 + 9
use quadratic formula (or polysolver) with a=5, b=-30 and c = 9
4th degree gives 4 solutions
x = +/- √(3 - 6/√(5))
x ~ +/- 2.38
x = +/- √(3 - 6/√(5))
x ~ +/- 0.563
</span>Determine which point is the highest (maximum) and the lowest (minimum) by putting the x-coordinates back into the original equation and comparing y-values.
* You will also need to check the endpoints given as these can sometime be the max/min of the function.
Our x-values:
x = { -3, -2.38, -0.563, 0.563, 2.38, 3}
respective y-values found by inputting x's into function
y = {0, 37.03, -3.34, 3.34, -37.03, 0}
nice symmetry.. check out the graph to see the solutions are correct.

Maximum point (-2.38, 37.03)
Minimum point (2.38, -37.03)
Answer:
A. x = 9
D. x = 0
Step-by-step explanation:
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
therefore
The solutions are x=0 and x=9
