Answer:
The quadratic equation 
has no real solution.
Step-by-step explanation:
Rewrite the quadratic equation in the standard form 
:
, for which:
The quadratic discriminant of is 
. The quadratic discriminant of would be:
.
Since the quadratic discriminant of this equation is negative, this quadratic equation has no real solution.
Answer:
Amplitude = 3
Step-by-step explanation:
Given
The sine curve above
Required
Determine the amplitude
To determine the amplitude of a sine curve, we have to calculate the distance between the horizontal line of the curve and the top or bottom of the function
Using the top of the curve as a point of reference;
Amplitude = Top of curve - Horizontal Line.
The horizontal line is always at point 0
From the graph above, the top of the curve is at point 3
Hence,
Amplitude = 3 - 0
Amplitude = 3
Answer:
hi
Step-by-step explanation:
x⁰+(x+90)⁰+(x-18)⁰=180⁰
3x+72=180
3x=180-72
3x=108
x=36
Q is equal to x+90=36+90=126
For cheking answer:
R is 36
Q is 126
P is 18
36⁰+126⁰+18⁰=180⁰
hope it helps
have a nice day
