Joey had $328. He found $5 in his pocket while walking to school. What was his percent increase?

Answer:

x^4-3x^3+x^2-4

mrk me brainliest plz

Step-by-step explanation:

Given the following functions

R(x) = 2x^4 – 3x^3 + 2x – 1 and

C(x) = x^4 – x^2 + 2x + 3

We are to find the profit function P(x)

P(x) = R(x) - C(x)

P(x) = 2x^4 – 3x^3 + 2x – 1 - ( x^4 – x^2 + 2x + 3)

P(x) = 2x^4 – 3x^3 + 2x – 1 - x^4 + x^2 - 2x - 3

Collect the like terms

P(x) = 2x^4-x^4-3x^3+x^2+2x-2x-1-3

P(x) = x^4-3x^3+x^2+0-4

P(x) = x^4-3x^3+x^2-4

Hence the required profit function P(x) is x^4-3x^3+x^2-4

Answer:

Different schedule Possible = 55,621,280

Step-by-step explanation:

Given - An English teacher needs to pick 9 books to put on his reading list for the next school year, and he needs to plan the order in which they should be read. He has narrowed down his choices to 13 novels, 17 plays, and 13 nonfiction books.

To find -  If he wants to include an equal number of novels, plays, and nonfiction books, how many different reading schedules are possible ?

Formula used -

Number of combinations of n things taking r at a time : [tex]^{n}C_{r}[/tex] = [tex]\frac{n!}{r! (n-r)!}[/tex]

Proof -

Given that, An English teacher needs to pick 9 books and wants to include equal number of novels, plays, and nonfiction books

i.e. he will Choose

3 books from Novels

3 books from Plays

3 books from Non-fiction books

Now,

Given that,

Total number of novel = 13

Total number of plays = 17

Total number of non-fiction books = 13

So,

Different schedule Possible = [tex]^{13}C_{3}* ^{17}C_{3}*^{13}C_{3}[/tex]

                                              = [tex]\frac{13!}{3! (13-3)!}* \frac{17!}{3! (17-3)!}* \frac{13!}{3! (13-3)!}[/tex]

                                               = [tex]\frac{13!}{3! (10)!}* \frac{17!}{3! (14)!}* \frac{13!}{3! (10)!}[/tex]

                                               = [tex]\frac{13(12)(11)10!}{3! (10)!}* \frac{17(16)(15)14!}{3! (14)!}* \frac{13(12)(11)10!}{3! (10)!}[/tex]

                                               = [tex]\frac{13(12)(11)}{3(2)(1)}* \frac{17(16)(15)}{3(2)(1)}* \frac{13(12)(11)}{3(2)(1)}[/tex]

                                               = [tex]{13(2)(11)}*{17(8)(5)}* {13(2)(11)}[/tex]

                                               = 55,621,280

⇒Different schedule Possible = 55,621,280

Answer:

64π^2  cubic inches

Step-by-step explanation:

The question is not complete, the shapes are not given

Diameter of base= 16π

Radius of base= 8π

Height of cylinder = 8 inches

Let us find the volume of the cylinder

V= πr^2h

V= π* (8π)* 8

V= 64π^2  cubic inches

Hence the volume of the cylinder is 64π^2  cubic inches

Answer:

Step-by-step explanation:

you know some things about the two angles they are the complimentary parts of just one of those perpendicular lines.   so you can say

180 = (6x + 5) + (3x+13)

180 = 9x +18

162 = 9x

18 = x

Answer:

Solution given;

6x+5+3x+13=180(sum of exterior angle is 180°)

9x=180-18

x=162/9

x=18 is a required answer.

Answer:

Option C

{ - ⁵/₃ , ³/₂ }

Step-by-step explanation:

6x² + x - 15 = 0

6x² + 10x - 9x - 15 = 0

2x(3x + 5) - 3(3x + 5) = 0

(2x - 3) (3x + 5) = 0

2x - 3 = 0 or 3x + 5 = 0

x = ³/₂ or x = - ⁵/₃

Thus, The answer is { - ⁵/₃ , ³/₂ }

Answer:

if you looking for estimate, it is about 138

without estimate, 137.5

Step-by-step explanation:

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Answer:

x=72

Step-by-step explanation:

180-36=144 (180 degrees in a triangle)

144/2=72

In the isosceles triangle having one angle is 36° and rest two equal angles are x then the value of x is, 72°

Any triangle with any two sides that have the same length is known as an isosceles triangle. An isosceles triangle has two angles that are equal in size and opposed to its equal sides.

In an isosceles triangle, the two equal angles are congruent, so we can call one of them "x". The sum of the angles in a triangle is 180°, so we can set up an equation to solve for x:

x + x + 36° = 180°

Simplifying the equation:

2x + 36° = 180°

Subtracting 36 from both sides:

2x = 144°

Dividing both sides by 2:

x = 72°

So, the value of x is 72°.

Answer:

x = 4 & 2

Step-by-step explanation:

-2x²+12x-16 = 0

-2(x²-6x+8) = 0 // Factor what's in the parentheses

-2(x-4)(x-2) = 0

-2(x-4) = (-2x+8)

(-2x+8) = 0 // Subtract 8 on both sides

-2x = -8 // Divide both sides by -2

x = 4

x-2 = 0 // Add 2 on both sides

x = 2

Answer:

m∠b=m∠c=61°

Step-by-step explanation:

The 119° angle and ∠b/∠c are supplementary angles. ∠b and ∠c are congruent because they are vertical angles and they are also both supplementary to the 119° angle. I will use b to find c.

[tex]b+119=180[/tex]

[tex]b=61[/tex]

Since b and c are equal, c=61 too.
