Solution given:
p(x)=0
-0.2x2 + 10x – 25=0
-0.2(x²-50x+125)=0
x²-2.25.x+25²=25²-125
(x-25)²=500
x-25=[tex] \sqrt{500} [/tex]
x-25=±10√5
taking positive
x=22.3606+25
x=47.3606
taking negative
x= -22.3606+25
x=2.639
so
maximum profit Anthony will receive :47.3606*1000= 47360600(approach)
now
47360 .6 or 2639 parts he would need to sell to receive the maximum profit

Answer:
x = 45
Step-by-step explanation:
The angles are supplementary
(2x + 40) + (3x - 85) = 180
Combine like terms
5x - 45 = 180
Add 45 to both sides
5x = 225
Divide both sides by 5
x = 45

what is this please!!!!! 20= -6+2n
Answer:
n = 13
Step-by-step explanation:
20= -6+2n
Add 6 to each side
20+6= -6+6+2n
26 = 2n
Divide each side by 2
26/2 = 2n/2
13 =n
Solve for b.
b - 16 = 83
b =
Answer:
Hello! answer: b = 99
Step-by-step explanation:
To find b we just have to add 83 + 16 so
83 + 16 = 99 and 99 - 16 = 83 So B = 99
Answer:
B=99

A solid with volume 8 cubic units is dilated by a scale factor of k to obtain a solid with volume V cubic units. Find the value of k which results in an image with each given volume.
a. 216 cubic units
k=
b. 1 cubic unit
k=
c. 1,000 cubic units
k=
Answer:
a. k = 27
b. k = 216
c. k = 0.216
Step-by-step explanation:
The value of the scale factor can be given by the following formula:
[tex]k = \frac{Final\ Volume}{Initial\ Volume}[/tex]
where,
Initial Volume = 8 cubic units
a.
Final Volume = 216 cubic units
Therefore,
[tex]k = \frac{216\ cubic\ units}{8\ cubic\ units}[/tex]
k = 27
b.
Final Volume = 1 cubic units
Therefore,
[tex]k = \frac{216\ cubic\ units}{1\ cubic\ units}[/tex]
k = 216
c.
Final Volume = 1000 cubic units
Therefore,
[tex]k = \frac{216\ cubic\ units}{1000\ cubic\ units}[/tex]
k = 0.216
The diameter of a truck wheel is 56.5 inches. What is the circumference of
the wheel?
Answer: 177.4999849 , or 56.5pi
Step-by-step explanation:
You simply divide the diameter by 2 to get the radius (28.25) and then plug into the circumference equation, 2*pi*r = Circumfrence.
Answer:
177.5 inches
Step-by-step explanation:
c = 2πr
d = r2
56.5/2=28.25
28.25x3.14= 88.705
88.705x2=177.41
Round, and you’ll get 177.5.

3(s+4)=s+10+2s
Distribute
3s+12=s+10+2s
Add like terms
3s+12= 3s+10
Subtract 3s from both sides
0 + 12=10

Is the figure a polygon? Is it convex or concave?
Answer:
This figure is not polygon and it is a concave
Step-by-step explanation:
A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides. Circles and shapes that include curves are not polygons - a polygon, by definition, is made up of straight lines.
And a convex is like a circle. But a concave having an outline or surface that curves inward like the interior of a circle or sphere.
