Answer:
Step-by-step explanation:
Looking at the arrows on the graph, it appears that as the graph keep growing UP unbounded, it also keeps growing to the left unbounded (to negative infinity, to be exact). Looking to the right, it appears that as the graph decreases unbounded (the y values keep getting smaller), the graph keeps growing in the x direct to positive infinity. So the domain is
- ∞ < x < ∞
Answer:
see explanation
Step-by-step explanation:
To find the intercepts, that is where the graph crosses the x and y axes.
• Let x = 0, in the equation for y-intercept
• Let y = 0, in the equation for x-intercept
x = 0 : 0 + y = - 9 ⇒ y = - 9 ⇒ (0, - 9 ) ← y- intercept
y = 0 : 8x + 0 = - 9 ⇒ x = -
⇒ ( -
, 0) ← x- intercept
Formula:
a^2+b^2=c^2
c^2: Is the hypotenuse.
For a^2 and b^2, you have to multiply both it by its self.
Then, add both.
Next, you square root it.
Example:
a^2+b^2=c^2
14^2+7^2=c^2
196+49=c^2
245=c^2
15.64=c^2
Answer:
B

Salutations!
<span>Are obtuse angles always, sometimes, or never equal to 180°?
Obtuse angles are angles </span>whose measure is greater than 90° and less than 180°. Its not always the case that an obtuse angle should be exact 180 °. So I reckon t would be sometimes, as its not always 180 °.
Hope I helped.
