Answer:
<h3>d. The roots are real, rational and equal.</h3>
Step-by-step explanation:
The discriminant of a quadratic equation is expressed using the equation:
D = b²-4ac. It talks about the nature of the roots of a quadratic equation.
If D>0, then the roots is real and unequal/distinct
If D<0 the roots are unreal and imaginary
If D = 0, the roots are real and equal (one real root)
According to this question, since the root given is a real value and also one value, then the the roots are real, rational and equal. Note that the root is rational since we can write it as a ratio of two integers e.g 34 = 34/1. 34 and 1 are integers
Answer:
-0.6
Step-by-step explanation:
-2.1--0.6= 1 1/2
2 negatives make a positive
Hello!
To find the slant height you use the equation
a^2 + b^2 = c^2
a is radius
b is height
c is slant height
Put in the values you know
9^2 + 17^2 = c^2
square the numbers
81 + 289 = c^2
Add
370 = c^2
Take the square root of the number
19.2 = c
The answer is B)19m
Hope this helps!
Answer:
The slope is 2
Step-by-step explanation:
To find the slope given two points, we use the formula
m = (y2-y1)/(x2-x1)
= (-4--2)/(2-3)
= (-4+2)/(2-3)
= -2/-1
= 2
