Answer:
10 sqrt(3)/3 =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp side /adj side
tan 30 = x/10
10 tan 30 =x
10 ( sqrt(3)/3) = x
10 sqrt(3)/3 =x
Answer:
It would be -5 + -6 = 65
Step-by-step explanation:
Add it up to together by removing the -
To answer this, you need to get "d" on one side by itself. To do this, add 8 to both sides of the equation.
d- 8 + 8 = 5 + 8
-8 and +8 cancel out leaving:
d = 13
Your answer is d = 13
Write the function as
f(x) = x² + 6x - 4
Note that
x² + 6x = (x + 3)² - 9
Therefore
f(x) = (x 3)² - 9 - 4
= (x + 3)² - 13
The vertex is at (-3, -13)., and the curve opens upward.
The axis of symmetry is x = -3.
Answer:
The vertex of the function is (-3, 13).
The graph increases over the interval (-3, -∞)
