Answer:
-75%
Step-by-step explanation:
The roots of the equation are 2 and k
substituting x=2 in the equation
(x+4)(x-p) = 2-x
(2+4)(2-p) = 2-2
6(2-p) = 0
dividing 6 both side, the answer is
p = 2
substituting x in the equation we
(x-4)(x-p) = 2-x
x² - 2x + 4x- 8 = 2-x
x² - 2x + 4x -8 -2 -x = 0
x² + 3x - 10 = 0
x² + 5x -2x - 10 = 0
x(x + 5) -2( x + 5) = 0
(x + 5)( x - 2) =0
(x + 5) = 0 or (x - 2) = 0
x = -5 and x = 2
therefor k = -5 and p = 2
R = 5(CA - 0.3)
<span>Multiply everything in the parenthesis by 5.</span>
R = 5CA - 1.5
Add 1.5 to both sides
1.5 + R = 5CA
Divide 5A on both sides.
C = 1.5 + R / 5A
Hope this helps!
h =
multiply both sides by 2 to eliminate the fraction
2A = ( b + c)h
isolate h by dividing both sides by (b + c)
h =
I’ll be assuming you meant k as in
the a in a quadratic equation:
ax^2 + bx + c
kx^2 + bx + c.
In this case, the “k” will indicate whether the graph will be opening upwards to form a “u” shape or it opens downwards to form a “n” shape
When “k” is positive, the graph would open upwards and form a “u”.
If “k” is negative, the graph would open downwards and form a “n”.
Have a great day ahead!
