product of (x+2y^2)(2x-2y^2)

**Answer:**

**Step-by-step explanation:**

(x + 2y²)(2x - 2y²)

**FOIL**

** F**irst

x(2x) = 2x²

* O*utside

x(-2y²) = - 2xy²

* I*nside

2y²(2x) = 4xy²

** L**ast

2y²(-2y²) = - 4y⁴

combine like terms

**2x² + 2xy² - 4y⁴**

Answer:

-4y^4 + 2xy^2 + 2x^2

Step-by-step explanation:

(x + 2y^2) (2x - 2y^2)

x(2x) + x(-2y^2) = 2x^2 - 2xy^2

2y^2(2x) + 2y^2(2y^2) = 2xy^2 + 4y^4

2x^2 - 2xy^2 + 4xy^2 - 4y^4

2x^2 + 2xy^2 - 4y^2

or

-4y^4 + 2xy^2 + 2x^2

**Answer:**

-1/3

i think.

**Step-by-step explanation:**

if it's to find slope

**Answer:**

m = -1/3

**Step-by-step explanation:**

There are two easy ways you can find the slope. The first one is using the rise over run method which is to first count how much you need to go up or down to get to the other point, and then how much you need to go forward. In this case you go down one, and forward three. This means its -1/3. You can also use the slope formula which uses the coordinates of each point. I attached it to this answer. (m representing slope)

Find the values of x and y

**Answer:**

x = 25, y = 19

**Step-by-step explanation:**

The external angle is supplementary to the adjacent internal angle.

2x +130 = 180

2x = 50 . . . . . . . subtract 130

** x = 25** . . . . . . . divide by 2

__

The external angle is equal to the sum of the remote internal angles.

130 = 54 +4y

76 = 4y . . . . . . . subtract 54

** 19 = y** . . . . . . . divide by 4

Which expression has a value of 8?

a: 10−(−2)

b: (−10)−(−2)

c:(−2)−(−10)

d: (−2)−10

**Answer:**

c:(-2)-(-10)

**Step-by-step explanation:**

When two minus symbols are next to each other in an expression, they become a plus sign.

a: 10-(-2)

10+2

12

b: (-10)-(-2)

-10+2

-8

c: (-2)-(-10)

-2+10

8

d: (-2)-10

-12

C.

-2 - -10= 8

The negative stays the same. The two dashes in between 2 and 10 become pluses.

10 - 2 = 8

The bigger number positive or negative is the dominant passing down their + or - to the value.

A cylinder and a cone both have radius of 6". The height of the cone is 12". The height of the cylinder is 6". Which has the greatest volume?

**Answer:**

cylinder has greatest volume

**Step-by-step explanation:**

solution

given,

radius of cylinder(r)=6cm

height of cylinder (h)=6cm

we know,

volume of cylinder=πr^2h

=22÷7×6×6×6

=4752÷7

=678.857cm^3

radius of cone(r)=6cm

height of cone(h)=12cm

we know,

volume of cone=1÷3πr^3

= 1÷3×22÷7×6×6×6

= 4752÷21

=226.2857cm^3

as a result,cylinder has greatest volume

Frank rented a truck for one day. There was a base fee of $18.99, and there was an additional charge of 76 cents for cach mile driven. Frank had

S152.75 when he returned the truck. For how many miles did he drive the truck?

**Answer:**

Frank drove 176 miles.

**Step-by-step explanation:**

Subtract the base fee from the total payment

152.75 - 18.99 = 133.76

divide the remaining amount(price for miles driven) by the cost for each mile

133.76 / .76 = 176

176 miles.

On solving the **linear equation** in one** variable**, given that there was a base fee of $18.99, and there was an additional charge of 76 cents for each mile driven, Frank had $152.75 when he returned the truck, the number of miles driven were 176 miles.

The** linear equations **in one **variable** is an** equation** which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a **variable**.

Let the number of miles driven be x.

Given in the question,

base fees = $18.99

charge per mile = 76 cents = $0.76

The** equation** of the total cost becomes :

= base fees + charge per mile * number of miles

= 18.99 + 0.76x

Given the total cost = $152.75

**Equating **the two values,

= 18.99 + 0.76x = 152.75

= 0.76x = 133.76

= x = 176

The x-value of the vertex of f(x) = x2 - 10x + 3 is

**Answer:**

x- coordinate = 5

**Step-by-step explanation:**

Given a parabola in standard form , f(x) = ax² + bx + c ( a ≠ 0 ) , then

The x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

f(x) = x² - 10x + 3 ← is in standard form

with a = 1 , b = - 10 , then x- coordinate of vertex is

x = - [tex]\frac{-10}{2}[/tex] = 5

A courtyard has the shape of a rectangle 45 ft and 28 ft wide. How long is a sidewalk from one corner diagonally to the opposite corner?

56 ft

47 ft

50 ft

53 ft

**Answer:**

53

**Step-by-step explanation:**

We use the pythagorean theorem, a^2 + b^2 = c^2. We can fill a and b for 45 and 28. 45^2 is 2025, and 28^2 is 784. Adding them up gives us 2809. The square root of 2809 is 53.

There are 14 European cities that Sam would eventually like to visit. On his next vacation, though, he only has time to visit 3 of the cities: one on Monday, one on Tuesday, and one on Wednesday. He is now trying to make a schedule of which city he'll visit on which day. How many different schedules are possible? (Assume that he will not visit a city more than once.)

**Answer:**

2184 different schedules

**Step-by-step explanation:**

Sam can make different schedules of the same three cities, so order of cities does matter, but no repetition is allowed. This makes this a permutation without repetition.

When we choose from n items, and we choose r of them, our formula is

n! / (n-r)!. We have 14 things to choose from, and 3 to choose, so our formula becomes

14! / (14-3)! = 14!/11! = 14*13*12 = 2184 different schedules

**Step-by-step explanation:**

Three cards are dealt from a shuffled standard deck of playing cards. Find the probability that the first card dealt is red, the second is black, and the third is red. (Enter your probability as a fraction.)

There are 52 cards in a deck, half the cards aware red and half the cards are red.

First card being red is 26/52 = 1/2

After the first card is dealt there are 51 cards left and 26 are black so dealing a black card = 26/51

After 2 cards are dealt there are 50 cards left and 25 red ones left. The probability would be 25/50 = 1/2

The probability of all 3 happening = 1/2 x 26/51 x 1/2 = 13/102

A pair of pants costs $24.60 when it is on sale for 25% off. What was the

original cost of the pants? (still....no labels!)

well, we know the pants are 25% off, that means the current sale price is only 75% of the original price, say the original price is "x" or 100%. So we know that $24.60 is 75%, what is the 100%?

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 24.6&75\\ x&100 \end{array}\implies \cfrac{24.6}{x}=\cfrac{75}{100}\implies \cfrac{24.6}{x}=\cfrac{3}{4} \\\\\\ 98.4=3x \implies \cfrac{98.4}{3}=x\implies 32.8=x[/tex]

Solve this system of equations using the Substitution method. Don't forget to write your final answer as a coordinate point. You must show all your work

3x + y = -2

y = 2x +3

The **substitution method** and writing the **solution **of the **system **in terms of** coordinate point** (x, y) = (-1, 1).

A **system **of **linear equation **is a group of one or more** linear equations **which can be solved by using a **simultaneous equation **or **elimination method. **

From the information given;

3x + y = -2 ----- (1)

y = 2x +3 ----- (2)

By using** substitution method, **we will replace the value of** equation (2) **into equation (1), by doing so, we have:

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

3x + 2x + 3 = -2

5x + 3 = -2

5x = -2 - 3

5x = - 5

x = -5/5

**x = -1 **

From equation (2), let's replace the value of x = - 1 into equation (2);

y = 2x + 3

y = 2(-1) + 3

y = -2 + 3

**y = 1**

Therefore, by using the **substitution method** and writing the **solution **of the **system **in terms of** coordinate point** (x, y) = (-1, 1).

a. The daily cost of keeping lit a 150-watt light bulb for 8 hours each day is $

(Round to three decimal places as needed.)

b. The yearly savings of replacing the 150-watt light bulb with a 20-watt light bulb is

(Round to two decimal places as needed.)

**Answer:**

P = 150 W * 60 sec/min * 60 min/hr = 540000 W-sec/hr

1 kW = 1000 W * 3600 sec = 3.6E6 W-sec

E (8 hrs) = 8 * .54E6 W-s = 4.32E6 W-sec

or E= 4.32/3.6 = 1.2 kW = .168 $/day

20/150 = .133 as much for a 20-watt bulb
