Evaluate the functions for the given input values.

g(-3) =
g(2) =
g(7) =

Answers

Answer 1

Answer:

g(-3) = 20

g(2) = 10

g(7) = 100

Step-by-step explanation:

g(x) = 2f(x) tells us that g(x) is two times f(x). Instead of f(x) we can write (x² + 1).

g(x) = 2f(x)

g(x) = 2(x² + 1)

Multiply.

g(x) = 2x² + 2

Now that we have g(x) we just substitute values in the function.

g(-3) = 2(-3)² + 2

        = 2(9) + 2

        = 18 + 2  

        = 20

g(2) = 2(2)² + 2

        = 2(4) + 2

        = 8 + 2  

        = 10

g(7) = 2(7)² + 2

        = 2(49) + 2

        = 98 + 2  

        = 100

Answer: Point C

Step-by-step explanation: I hope this helped! :D

Two players, A and B, are playing an asymmetrical game. There are n points on the game board. Each turn player A targets a pair of points and player B says whether those two points are connected or unconnected. A can target each pair only once and the game ends when all pairs have been targeted. Player B wins iff a point is connected with all other points on the very last turn, while player A wins if any point is connected with all other points on any turn but the very last one OR if no point is connected to all other points after the last turn. For what values of n does either player have a winning strategy?​

Answers

The values of n that either player has a winning strategy is when the number of points are odd such as 3:-

How to depict the strategy?

The game is begun by A and then its chance of B to play the game alternatively, then all the possible moves are 1,2; 2,3; 1,3 in which all possible pairs are selected.

If the game end on an even number of moves then the game is won by A. For B to win, these points should be connected at the very end of the game.

Similarly, for even number of moves B wins the game when number of points is odd.

If the number of points is even the opposite of this happens that is, for even moves B wins and for odd number of moves A wins.

15% of what number is equal to 9

Answers

Answer:

9 is 15% of 60.

Step-by-step explanation:

[tex]\text{Formula}=\frac{\text{Number x 100}}{\text{Percent}} =\frac{9 \times100}{15} =60[/tex]

Following shows the steps on how to derive this formula and find out 15% of what number is 9.

Step 1: If 15% of a number is 9, then what is 100% of that number? Setup the equation.

[tex]\frac{9}{15} = \frac{Y}{100}[/tex]%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

[tex]15Y=6\times100\\15Y=600[/tex]

Y = [tex]\frac{600}{100} =60[/tex]

The requried 15% of 60 is equal to 9, as of the given percentage situation.

What is the percentage?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
To find the number that 15% of is equal to 9, we can set up a proportion:

15% of x = 9

Converting 15% to a decimal:

0.15x = 9

Dividing both sides by 0.15 gives:

x = 60

Therefore, 15% of 60 is equal to 9.

It is defined as the four-sided polygon in geometry having four edges and four corners. Two pairs of congruent sides, and it has one pair of opposite congruent angles.

We know the area of the kite = pq/2

Where p and q are the length of the diagonals

p = 10+10 = 20 ft

q = 7+11 = 18 ft

Area = (20×18)/2

-a-10 = 5a +8 pleasee help me

Answers

Answer:

a=-3

Step-by-step explanation:

5a+a=-10-8

6a=-18

a=-18/6

a=-3

Answer:

  a = -3

Step-by-step explanation:

This is a linear equation in one variable that has a constant term and a variable term on each side of the equal sign. It can be solved in 3 steps, so can be called a "3-step equation."

The three steps involve separating the variable and constant terms, then dividing by the variable's coefficient.

__

  -a -10 = 5a +8 . . . . . . given

step 1

To separate the variable and constant terms, we eliminate one of the variable terms by adding its opposite to both sides of the equation. It is generally convenient to choose the variable term with the lowest coefficient value. When we add the opposite of that to both sides of the equation, the resulting variable term will have a positive coefficient. (Dealing with positive numbers generally reduces errors.)

Here the two variable terms are -a and 5a. The coefficient -1 is less than the coefficient 5, so we choose to add the opposite of -a to both sides.

  -a +a -10 = 5a +a +8 . . . . . add a to both sides

  -10 = 6a +8 . . . . . . . . . . . simplify

step 2

Now there is only one variable term, but it has a constant added to it. We can eliminate that constant by adding its opposite.

  -10 -8 = 6a +8 -8 . . . . . add -8 to both sides

  -18 = 6a . . . . . . . . . . . simplify

step 3

This equation gives us the value of a multiple of the variable (6a). To get the variable by itself, we multiply by the reciprocal of the variable's coefficient. The product of the coefficient and its reciprocal is 1, so we will have the variable alone.

Multiplying by 1/6 is the same as dividing by 6. Often, it is easier to think in terms of division. However, when the coefficient is a fraction, it can be useful to think in terms of multiplying by the reciprocal of that fraction.

  (1/6)(-18) = (1/6)(6a) . . . . . . multiply by 1/6

  -3 = a . . . . . . . . . . . . . . . simplify

The solution to the equation is a = -3.

_____

Additional comment

When we say "add" or "multiply" the equation by some number, we mean that operation to be performed on both sides of the equation. The properties of equality say we can do whatever we like to an equation, as long as we do the same thing to both sides of the equation.

Step-by-step explanation:

Step 1: Write down the number as a fraction of one:

1.7 = 1.7/1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,

1.7/1

= (1.7 × 10)/ (1 × 10)

= 17/10

(This fraction is alread reduced, We can't reduce it any further).

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 17/

Answer:

(5, 12 )

Step-by-step explanation:

3x + 2y = 39 → (1)

5x - y = 13 → (2)

multiplying (2) by 2 and adding to (1) will eliminate y

10x - 2y = 26 → (3)

add (1) and (3) term by term to eliminate y

13x + 0 = 65

13x = 65 ( divide both sides by 13 )

x = 5

substitute x = 5 into either of the 2 equations and solve for y

substituting into (1)

3(5) + 2y = 39

15 + 2y = 39 ( subtract 15 from both sides )

2y = 24 ( divide both sides by 2 )

y = 12

solution is (5, 12 )

If sin Q = 4/5, cos P + cos Q

Answers

The value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We know that:

P + Q are complementary, which means that

P+Q = 90°

Then R is a right angle, i.e. it measures 90°.

sin(90-x) = cos (x)

cos(90-x) = sin (x)

Then sinQ = 4/5  

cos(90-Q) = cosP = 4/5

Now sin²(P) + cos²(P) = 1

sin²(P) = 1 - cos²(P)

sin²(P) = 1 -[4/5]² =9/25

sin(P) = 3/5

cos(Q) = sin(P) = 3/5

cos(P) + cos(Q) = 4/5 + 3/5 = 7/5

Thus, the value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.

Given:

Charles has $50.00                             (total)Charles spent 1 / 4 on a gift card        (spent means subtract from total)Charles spent 5 / 8 on a new wallet   (spent means subtract from total)

Required:

The question asks: “How much money is leftover?” From this we know we have to find the leftover amount. Find: x = ?

Analysis:

50 (total) = x + 1/4 + 5/8 than solve for x

how much money leftover (x)

= total - spent on gif card - spent on new wallet

x = 50 - 1 / 4 - 5 / 8

Solution:

x = 50 - 1/4 - 5/8

1/4 of 50 is 50 / 4 = 12.5

x = 50 - 12.5 - 5/8

5/8 of 50 is 50/8 = 6.25    this is 1/8 of the pricethan multiply by 5 to get 5/8, 6.25 x 5 = 31.25

x = 50 - 12.5 - 31.25

x = 6.25

Statement:

We found that the leftover amount is $6.25.

Therefore, the leftover amount of money with a starting amount of $50.00 and purchasing a gift card and new wallet is in fact $6.25.
