Ok so Candy draws a square design with a side length of x inches for the window at the pet shop. She takes the design to the printer and asks for a sign that has an area of
16x^2-40x+25square inches.
Let y(x) =16x^2-40x+25
If differentiating both sides w.r.t x we get
y'(x)=32x-40
And
to find critical point x ,Put y'(x)=0 then
32x-40=0
x=5/4
8 with a remainder of 10 or 8 and 10/15 orrrrr 8 and 1/3
Answer:
x > 3
Step-by-step explanation:
Given 2 sides of a triangle then the third side x will be
difference of sides < x < sum of sides , that is
15 - 12 < x < 15 + 12, so
3 < x < 27
Thus x > 3
Rewrite it as
3r-1=8
3r=8+1
3r=9
R= 3
To graph the equation of the line, find the x-intercept and the y-intercept of the function
we have

we know that
The x-intercept is the value of x when the value of y is equal to zero
The y-intercept is the value of y when the value of x is equal to zero
Step 1
<u>Find the x-intercept</u>
For 



the x-intercept is the point 
Step 2
<u>Find the y-intercept</u>
For


the y-intercept is the point 
Step 3
Graph the points and draw the line
see the attached figure
therefore
the answer in the attached figure
