What is the image of (−5,9) after a reflection over the y-axis?

Answer:

−π

----

4

Step-by-step explanation:

Alright, archtan /

tan

−

1

(

x

)

is the inverse of tangent. Tan is

sin

cos

. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4.

Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan(-1) equal. Using the unit circle we can see that tan(1)= pi/4.

Since the "Odds and Evens Identity" states that tan(-x) = -tan(x). Tan(-1)= -pi/4.

Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.

Answer:

Yes you are right.

Step-by-step explanation:

Once you divide 128.25 by 3 you will get 42.75

Then you multiply 42.75 by 5 and you will get 213.75.

Answer:

C

Step-by-step explanation:

Answer:

D)  f(x)=4x-3

Step-by-step explanation:

ok so use slopeintercept form

why=mx+b

just joking its

y=mx+b

m=slope

b=y-intercept

x=number

so knowing this

lets find the slope

slope=rise/run

so if you see the y changes every 4 on each x

when x is 1 y is 1 and when x is 2 the y adds 4 and y is 5

so slope is 4

knowing the slope

y-intercept is where (0,y)

x=0

subtract 4 from 1 because 1 is the x

f(x)=4x-3

Answer:

Small flags = 108

large flags= 47

Step-by-step explanation:

Step one:

given

let the number of small lag be x

and big flags be y

so

3.5x+6.5y= 683.5----------1

x+y=155------------------------2

Step two:

from eqn 2 x= 155-y

put x= 155-y in  eqn 1

3.5(155-y)+6.5y= 683.5

542.5-3.5y+6.5y=683.5

collect like terms

3y=141

divide by 3

y= 141/3

y=47

Step three:

put y= 47 in eqn 2

x+47=155

x= 155-47

x=108

Answer: [tex]1.0308\text{ miles}[/tex]

Step-by-step explanation:

Distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] :

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The ranger station is located (2.5, 3.5) and the nature center is located at (0.5, 4) .

Distance between ranger station and nature center

[tex]\sqrt{(2.5-0.5)^2+(3.5-4)^2}=\sqrt{2^2+(-0.5)^2}\\\\=\sqrt{4+0.25}\\\\=\sqrt{4.25}\\\\=2.0616\text{ units}[/tex]

Each unit in the map is equal to 0.5 mile.

Hence, Distance between ranger station and nature center  = [tex]2.0616\times0.5=1.0308\text{ miles}[/tex]

Answer:

C.-9, -1, -3,5

Step-by-step explanation:

Given

y = 2x - 3 ---- [missing equation]

Required

Complete the table

To do this, we simply substitute the values of x in the given equation.

When x = -3

y = 2 * -3 - 3

y = -6 - 3

y = -9

When x = 1

y = 2 * 1 - 3

y = 2 - 3

y = -1

When x = 0

y = 2 * 0 - 3

y = 0 - 3

y = -3

When x = 4

x = 2 * 4 - 3

y = 8 - 3

y = 5

Hence, the missing gap can be filled with: C.-9, -1, -3,5

Step-by-step explanation:

the negative number is -1

the positive number is 13.5

Answer:

k = 3

Step-by-step explanation:

By the Remainder theorem if f(x) is divided by (x + h) , then the remainder is f(- h), thus

f(- 3) = (- 3)³ + 2k(- 3)² + 3(- 3) - 6 = 12 , then

- 27 + 18k - 9 - 6 = 12

18k - 42 = 12 ( add 42 to both sides )

18k = 54 ( divide both sides by 18 )

k = 3

Answer:

g(2) = 14

Step-by-step explanation:

g(x) = 3x + 8

g(2) = 3(2) + 8

g(2) = 14

g(2)=14 Hope this helps

Answer:

$17.94

Step-by-step explanation:

Step one:

given

the cost price of snow globes = $9.20

mark up percent= 95%

Required:

the retail selling price

Step two:

let us find 95% of $9.20

=95/100*9.20

=0.95*9.20

=$8.74

Hence the retail selling price is = 9.20+8.74

=$17.94

Answer:

Exact Form: x=11/2

Decimal Form: x=5.5

Mixed Number Form: x=5 1/2

Step-by-step explanation:

earrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    14-(3+2*x)=0  

Step by step solution :

STEP  1:

Solving a Single Variable Equation:

1.1      Solve  :    -2x+11 = 0  

Subtract  11  from both sides of the equation :  

                     -2x = -11

Multiply both sides of the equation by (-1) :  2x = 11

Divide both sides of the equation by 2:

                    x = 11/2 = 5.500

Answer:

82.67 tickets

Step-by-step explanation:

Since the tickets are shared equally, the number of tickets each friend would receive is given as: x

The total number of tickets = 248 tickets

Hence:

248 = 3 × x

3x = 248

x = 248/3

x = 82.666666667 tickets

x ≈ 82.67 tickets

Hence, each friend would receive about 82.67 tickets
