3. f(x) = x2 + 4x - 2

3. F(x) = X2 + 4x - 2

Answers

Answer 1

Answer:

f(x)= -(x-2)^2+2

Step-by-step explanation:

the same valuve needs the be added to both sides

f(x)+?= -x^2+4x+?-2

to complete the square -x^2+4x-4= -(x-2)^2 add the -4 to the expression

f(x)+?= -x^2+4x-4-2

since -4 was added to the right side, also add -4 the the left side

f(x)-4= -x^2+4x+?-2

now factor out the negative sign from the expression

f(x)-4= -(x^2-4x+4)-2

using a^2-ab+b^2=(a-b)^2

f(x)-4= -(x-2)^2-2

move the constant the the right side and change its sign

f(x)= -(x-2)^2-2+4

now calculate the sum

f(x)= -(x-2)^2+2

Find the mass of the object if it has a volume of 20 mL and a density of 3 g/mL.

Answers

Answer:

60 g

Step-by-step explanation:

Use the density formula, D = m/v, where m is the mass and v is volume

Plug in the volume and density, then solve for the mass:

D = m/v

3 = m/20

60 = m

So, the mass is 60 g

Given :

Volume of object = 20 mL

Density of object = 3 g/mL

To Find :

We have to find mass of the object[tex].[/tex]

Solution :

★ Density is defined as the mass of object per unit volume.

It is a scar quantity having only magnitude.

Mathematically, ρ = M/V

ρ denotes densityM denotes massV denotes volume

By substituting the values, we get

⭆ 3 = M/20

⭆ M = 3 × 20

M = 60 g

∴ Mass of the object is 60g.

Elias bought 7 new shirts for school.
Five shirts cost $60.90. He also bought
a pair of pants for $14.99. Without tax,
what is the total amount Elias spent?

Answers

Answer:

$100.25

Step-by-step explanation:

This question says that 5 shirts cost $60.90, so you would divide the two numbers to find out the price of 1 shirt

$60.90÷5=$12.18

Then you would just solve this equation

T=$12.18x+$14.99

T= Total Money Spent

x= Number of Shirts

Plug in the 7 shirts and solve

T=$12.18(7)+$14.99

T=$85.26+$14.99

T=$100.25

A group of friends bought 6 movie tickets. they used a coupon for $2.00 off the cost of one of the tickets, and their total cost with the coupon was $50.50. write an equation that can be used to determine the regular cost C of each movie ticket​

Answers

Answer:

each ticket is $8.75

Step-by-step explanation:

c=8$8.75

The equation that can be used to determine the cost of each movie ticket is C = $48.50 / 6.

What is the equation that can be used to determine the cost of each movie ticket?

Total cost of the 6 movie tickets = (6 x cost of each ticket) - value of one coupon

50.50 = 6C - $2

Combine similar terms

$50.50 - $2 = 6C

$48.50 = 6C

Divide both sides of the equawtion by 6

C = $48.50 / 6

A. is .97

B. is 1.01

C. . is .91

D. is .94

So C. has the lowest value

The number which has the lowest value is 0.23 +0.23 +0.45, the correct option is C.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Given;

A 0.30 +0.54 +0.13

B 0.10 +0.66 +0.25

C 0.23 +0.23 +0.45

0.30+ 0.41 +0.23

Now

A 0.30 +0.54 +0.13=0.97

B 0.10 +0.66 +0.25=1.01

C 0.23 +0.23 +0.45=0.91

0.30+ 0.41 +0.23=0.94

Therefore, the algebra with lowest value will be 0.23 +0.23 +0.45

and volleyball, 15 played both basketball and chess and 5 played both
three events. How many played chess only, basketball only and volleyball
only? How many students are there in all?

Answers

Answer:

Explained below.

Step-by-step explanation:

Denote the events as follows:

C = chess

V = volleyball

B = basketball

The data provided is as follows:

n (C) = 30

n (V) = 19

n (B) = 25

n (C ∩ V) = 14

n (B ∩ V) = 8

n (B ∩ C) = 15

n (C ∩ V ∩ B) = 5

Consider the Venn diagram below.

The number of students who played only chess is marked in pink:

n (Only C) = 6

The number of students who played only volleyball is marked in blue:

n (Only V) = 2

The number of students who played only basketball is marked in orange:

c. What is the probability that neither Jerry nor Kramer will show up? (Round your answer to 2 decimal places.)
Probability

Answers

Answer:

a. 0.41

b. 0.87

c. 0.13

Step-by-step explanation:

From the above question:

We are told that:

Probability that Jerry will not show up = 41% = 0.41

Probability that Jerry will show up =

100 - 41 = 59 = 0.59

Probability that Kramer will not show up = 31% = 0.31

Probability that Kramer will show up

= 100 - 31 = 69% = 0.69

Even though Jerry and Kramer know each other, their decisions can be assumed to be independent.

a. What is the probability that both Jerry and Kramer will show up? (Round your answer to 2 decimal places.)

= P(A) × P(B)

= Probability the Jerry will show up × Probability that Kramer will show up

= 0.69 × 0.59

= 0.4071

≈ 2 decimal places = 0.41

b. What is the probability that at least one of them will show up? (Round your answer to 2 decimal places.)

Probability = 1 - the probability that both Jerry and Kramer will not show up

= 1 - (0.41 × 0.31)

= 1 - 0.1271

= 0.8729

Approximately to 2 decimal places = 0.87

c. What is the probability that neither Jerry nor Kramer will show up? (Round your answer to 2 decimal places.)

Probability = Probability the Jerry will not show up × Probability that Kramer will not show up

= 0.41 × 0.31

= 0.1271

To 2 decimal places = 0.13

1. (12 points) The tennis team at Taft High School has 8 players, and the tennis team at McKinley High School has 7 players. Rebecca is on the team at Taft, and her sister Leah is on the team at McKinley. The two teams are going to play a tournament with 4 rounds. In each round, one player from Taft will play a match against one player from McKinley. Each player can play in at most one match. A schedule for the tournament consists of an ordered list of the names of the players from each school who will play in each of the four rounds. The schedule does not include the results of each match.

(a) How many schedules are there?

(b) How many schedules include neither sister?

Answer:

a

   [tex]N  =  1,411,200[/tex]

b

  [tex]M  =  302, 400[/tex]

Step-by-step explanation:

From the question we are told that

   The  number of players in Taft High School is t =  8

    The  number of players in McKinley High School  is k = 7

   The number of rounds is  n  =  4

   The highest number of match each player can play is  w =  1

   

Generally the total number of schedules is  

      [tex]N  = ^tP_4 * ^k P_4[/tex]

      [tex]N  = ^8P_4 * ^7 P_4[/tex]

=>   [tex]N  =  \frac{8!}{(8-4)!} * \frac{7!}{(7-4)!}[/tex]

=>   [tex]N  =  \frac{8!}{4!} * \frac{7!}{3!}[/tex]

=>  [tex]N  =  \frac{8*7 *6*5*4*3*2*1}{4*3*2*1} * \frac{7*6*5*4*3*2*1}{3*2*1}[/tex]

=>  [tex]N  =  1,411,200[/tex]

Generally the  number of schedules that include neither of the sisters is  mathematically represented as

        [tex]M= \ ^{t-1}P_4 *\ ^ {k-1} P_4[/tex]

        [tex]M= \ ^{8-1}P_4 *\ ^ {7-1} P_4[/tex]

=>    [tex]M= \ ^{7}P_4 *\ ^ {6} P_4[/tex]

=>     [tex]M  =  \frac{7!}{(7-4)!} * \frac{6!}{(6-4)!}[/tex]

=>     [tex]M  =  \frac{7!}{3!} * \frac{6!}{2!}[/tex]

=>     [tex]M  =  \frac{7 *6*5*4*3*2*1}{3*2*1} * \frac{6*5*4*3*2*1}{2*1}[/tex]

=>      [tex]M  =  302, 400[/tex]

Simplify the following expression.
44[(9 + 3) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (3.5 2)) - 9]

Answers

The value of the expression is 2419.

The required answer is 2400.5

What is simplification?

Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube  roots, plus and minus.

Now the given expression is,

44[(9 + 3) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (3.5 - 2)) - 9]

It can be simplified using PEMDAS rule.

P is parenthesis

E is exponents

M is multiplication

D is division

A is addition

S is subtraction

Firstly we will solve parenthesis, thus

44[(9 + 3) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (3.5 - 2)) - 9]

= 44[(12) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (1.5)) - 9]

= 44[12 + 72 - 6 * 2.5 - 19] - [42 - 3(78.5) - 9]

Now we will solve multiplication,

= 44[12 + 72 - 15 - 19] - [42 - 235.5 - 9]

Now we will solve addition,

= 44[84 - 15 - 19] - [42 - 235.5 - 9]

Now we will solve subtraction,

= 44[84 -34] - [42 - 244.5]

= 44[50] - [42 - 244.5]

= 44[50] - [-200.5]

= 2200+  200.5

= 2400.5

Thus, the required answer is 2400.5
