Answer:
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola.
Step-by-step explanation:
<span>If x= side of the square, and A = area of square, then
A = x^2
dA/dx = 2x, or
dA = 2x*dx, where dx is the differential in x (same as error)
dA/A = 2x*dx/(x^2) = 2*dx/x = 2*(0.05cm)/(15cm) = 0.00667 = 0.667%
for b):
if dA/A = 0.025 = 2*dx/x, then
dx/x=(0.025)/2 = 0.0125 = 1.25 %
I hope I helped. :)</span>
<h3>
The two solutions are: x = 0 and x = 1/2</h3>
====================================================
Work Shown:
10x^2 - 5x = 0
5x(2x - 1) = 0 .... factor out the GCF
5x = 0 or 2x-1 = 0 .... zero product property
x = 0/5 or 2x = 1
x = 0 or x = 1/2
Note: 1/2 = 0.5
We could use the quadratic formula here, or we could complete the square, but that's overkill in my opinion.
Answer:
The lines will never intersect.Step-by-step
explanation:
The slope of the cups is the same, 1.5. The y-intercept of the small cups is 6The y-intercept of the big cups is 9. This means that the lines will never intersect because they are parallel lines and have the same slope but different y-intercepts.
I hope this helps :) Please give brainliest! :)
