Answer:
the domain for this parabola is all real numbers
Answer:
17.97=x
Step-by-step explanation:
tan theta = opposite side/ adjacent side
tan 38 = x /23
Multiply each side by 23
23 * tan 38 = x/23 * 23
23 tan 38 = x
17.96956941 =x
To the nearest hundredth
17.97 =x
Answer:
choice C. Perfect square trinomial is correct.
Step-by-step explanation:
We need to find the pattern which is represented by the polynomial 
.
To find that pattern, we need to factor
which is a perfect square.
Hence choice C. Perfect square trinomial is correct.
Answer:
Parallel: y=-4x-1
Perpendicular: y=-4x+13/2
Step-by-step explanation:
For the equation y=-4x-41, the slope is -4. Writing a line related to this equation has two options:
- If the line will be parallel to it then this is the slope of the new line as well. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-7)=-4(x--2)
y-7=-4x-8
y=-4x-1
- If the line will be perpendicular to it then the slope is the negative reciprocal of the previous slope. It is 1/4.
(y-7)=1/4(x--2)
y-7=1/4x-1/2
y=-4x+13/2
