A sporting equipment company wants to sell a new bicycle helmet. They have developed a function, shown below, where total profit, p, can be determined based on sale price, s.



What will be the total profit if the sale price of the helmet is $60?

Answers

Answer:

[tex] p(s) = -24s^2 +2200 s -18000[/tex]

If we use the valie of s =60 we have

[tex] p(60) = -24 (60)^2 +2200*60 -18000[/tex]

And after solve we got:

[tex] p(60)= -86400 +132000 -18000 =27600[/tex]

So then the best option for this case would be:

$27,600

Step-by-step explanation:

Using the following info in order to complete the problem:

p(s)=-24s^(2)+2200s-18000

$112,560

$27,600

$111,120

$236,400

$14,240

We have the following function given:

[tex] p(s) = -24s^2 +2200 s -18000[/tex]

If we use the valie of s =60 we have

[tex] p(60) = -24 (60)^2 +2200*60 -18000[/tex]

And after solve we got:

[tex] p(60)= -86400 +132000 -18000 =27600[/tex]

what are the factors of m squares minus 12m plus 20 ?

Answers

Answer:

(m - 10) and (m - 2)

Step-by-step explanation:

Given

m² - 12m + 20

Consider the factors of the constant term (+ 20) which sum to give the coefficient of the m- term (- 12)

the factors are - 10 and - 2, since

- 10 × - 2 = + 20 and - 10 - 2 = - 12, thus

m² - 12m + 20 = (m - 10)(m - 2)

Answer:

y = 80

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5 , thus

sum = 180° × 3 = 540°

Sum the internal angles and equate to 540

110 + y + 2y + y + 110 = 540 , that is

4y + 220 = 540 ( subtract 220 from both sides )

4y = 320 ( divide both sides by 4 )

y = 80

Answers

Answer:

9.30%

Step-by-step explanation:

Given;

The average rate in the national average N = 8.3%

The average rate in Maryland R = 12% higher than national

R = N + 12% of N

R = N + 0.12N

R = 1.12N

R = 1.12 × 8.3%

R = 9.296%

R = 9.30%

Rate of diabetes in Maryland = 9.30%

Answers

Answer:

Translation, Reflection, Rotation

Step-by-step explanation:

In mathematics, objects undergo series of transformations. Transformation can be defined as the movement of an object from one particular position to another position

The transformations that an object undergoes are such that the resulting figure created is SIMILAR TO OR THE SAME AS the original figure is referred to as ISOMETRIC TRANSFORMATIONS.

They are:

a) Translation: The movement that occurs in translation of objects is the sliding movement. During translation, an objects is moved from one point to another point without rotating or reflecting the object. This is also known as sliding.

b) Reflection: During reflection, an object is transformed turning it over the line of reflection to another side or position.

c) Rotation: Rotation is the transformation of an object by rotating the object about a fixed point.
