Graph the function for the given domain.

y = x2 − 4 D:{−2, −1, 0, 1, 2}

Answer:

r = 0.16

Step-by-step explanation:

C = 2·π·r

1 =  2·π·r

1/2 =  π·r

0.5 =  π·r

0.5 / 3.14 = r

0.16 = r

Answer:

The width of parking lot is 30 yards.

Step-by-step explanation:

Given that:

Area of rectangular parking lot = 1650 yards square

Length of parking lot = 55 yards

Width of parking lot = x yards

Area of rectangle is given by:

A = Length * Width

1650 = 55x

Dividing both sides by 55

[tex]\frac{55x}{55}=\frac{1650}{55}\\x=30[/tex]

Hence,

The width of parking lot is 30 yards.

Answer:

48

Step-by-step explanation:

Given ratio of males to females at a party is 3 : 5.

Let the numbers of males and females be 3x and 5x respectively.

According to the given description:

No of females = No of males + 13

Therefore,

5x = 3x + 12

5x - 3x = 12

2x = 12

x = 12/2

x = 6

No of people at the party

= 3x + 5x

= 8x

= 8*6

= 48

Answer:

x = 10, y = [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

The opposite sides of a parallelogram are congruent.

For LMNO to be a parallelogram then

ON = LM and OL = NM, that is

ON = LM

7x - 6 = 6x + 4 ( subtract 6x from both sides )

x - 6 = 4 ( add 6 to both sides )

x = 10 , then

NM = x - 9 = 10 - 9 = 1 and

OL = NM , that is

3y - 3 = 1 ( add 3 to both sides )

3y = 4 ( divide both sides by 3 )

y = [tex]\frac{4}{3}[/tex]

Answer:

28% of the class didn't pass the test.

Step-by-step explanation:

25 - 18 = 7

7/25 = 0.28  or 28%

Thus, 28% of the class didn't pass the test.

Answer:

13

Step-by-step explanation:

Replace X with 2

Evaluate the function. g(x) = 3x^2 – 2x + 5 Find f(2)​

g(x) = 3(2)^2 – 2(2) + 5

Next conduct PEMDAS

Exponents are first so solve 2^2 which is 2 x 2 = 4

g(x) = 3(4) – 2(2) + 5

Next step is multiplication multiply 3 x 4 and 2x2

g(x) = 12 – 4 + 5

conduct adding and subtracting left from right

g(x) = 13

Answer:A

Step-by-step explanation:

Answer: 8 and 2

Step-by-step explanation:

this is simple, since we only have 10 numbers to work with. i just kept experimenting with numbers until i got one that had a difference of 6. no strategy, just brain power. hope this helps! xoxo

Answer:

So negatove numbers are gonna be impossible becuase we know that the highest we can go is -10+20=10 but it’ll give a whole different difference when subtracted.

And it can’t be greater then 10 becuase if you do add them it won’t be 10

SO it has to be between 1-10

So what equals 10?

5/5

2/8

8/2

6/4

4/6

3/7

7/3

Now 5 and 5 is out cause if subtracted its 0

2/8  and 8/2 works, if added you get 10 but when subtracked the way for 8/2 from left to write it’ll give 6 which is the only one which will give.

final answer the two numbers are 8 and 2

Answer:

150 labels/ minute

Step-by-step explanation:

As you can see on the graph there is a point on (1,1 1/2)=150/1

Also 150*2=300 so it all makes sence

After solving the equation, the smaller piece length of the rope will be 30 meters.

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the data provided in the given question,

3x+20+x = 140

4x+20 = 140

4x = 120

x = 30 meters

The smaller piece of the rope is of 30 meters.

Answer:y=2x

(Slope=2)

Step-by-step explanation:

The ratio is 1 to 2y is to times x y=2x

Step-by-step explanation:

sin2x - sinx = 0

2sinxcosx - sinx = 0

(Double Angle Formula)

sinx(2cosx - 1) = 0

Either sinx = 0 or cosx = 1/2.

When sinx = 0,

x = 0 or x = π.

When cosx = 1/2,

x = π/3 or x = 5π/3.

Hence the solutions are

x = 0, x = π/3, x = π or x = 5π/3.

Answer:

x = -3.5

Step-by-step explanation:

POE = PROPERTY OF EQUALITY

3*2 + 2x + 1 = 0

6 + 2x + 1 = 0 ## ^ Multiplication

7 + 2x = 0 ## ^ Combine like-terms

2x = -7 ## ^ Subtraction POE

x = -3.5 ## ^ Division POE

Answer:

X=0

Step-by-step explanation:

Use PEMDAS to get rid of some things. Do 3 x 2 = 6. Then distribute the like terms to one side seperating 2x and "0": +1 ---> 0-1 = -1. Now divide... 2x/2 = x (cancels out) and 0/2 = 0. Therefore X=0. But I'm not a computer so double check your answer.
