Answer:
Domain: (-11, 4)
Step-by-step explanation:
Domain is the set of all x-values that can be inputted into a function.
So we look at x-values that can be inserted into the graph.
We notice that we cannot input x = -11 or x = 4 as it is open-pointed but everything inbetween works, so we have (-11, 4) as our domain.

Ao cobrar uma falta em um jogo de futebol, uma jogador imprime à bola a uma velocidade de 43,2 km/h. Sabendo que a bola gasta 3 s até atingir as redes, determine a distância percorrida? A)16m B)36m C) 30m D)12m E) 24m
Answers
Answer:
B
Step-by-step explanation:
Nesta questão, estamos interessados em calcular a distância percorrida se um jogador correr a uma velocidade de 43,2 km / h por 3 segundos.
Matematicamente; a distância percorrida = velocidade * tempo
O problema que temos aqui é que nossas unidades não são consistentes.
A melhor maneira de fazer isso é ter unidades consistentes em metros por segundos e segundos, pois nossa resposta está em metros.
Portanto, a conversão que precisamos fazer aqui é converter 43,2 km / h em metros por segundo Matematicamente, sabemos que existem 1000 m em um quilômetro.
Da mesma forma, uma vez que 60 segundos fazem um minuto e 60 minutos fazem uma hora, o número de segundos em uma hora é 60 * 60 = 3.600 segundos
Assim, convertendo 43,2 km / h em m / s, temos; (43,2 * 1000) / 3600 = 12 m / s
Portanto, a distância percorrida em metros seria agora; velocidade em m / s * tempo em segundos = 12 m / s * 3 segundos = 36 m
Nine years ago, Tarah opened a savings account with her bank. She started with a balance of $359 and has not made any withdrawals or deposits since then. If her interest rate is 8% each year, how much interest has accrued using simple interest? Total Interest = $ What is Tarah's new total balance? New Balance Total = $
Answers
Answer:
Total- 617.48 Interest- 258.48
Step-by-step explanation:
First, we need to find out what 8% of 359 is.
.08 times 359 = 28.72. This is how much interest is gained in a year. Since she waited 9 years, we multiply 28.72 by 9 and get 258.48. This is the total interest.
Now we just add 258.48 and 359 to get 617.48.
Answer:
617.48
Step-by-step explanation:
SI = P x R x T / 100
SI = Simple Interest
P = Principal
R = Rate
T = Time
SI = 359 x 9 x 8 / 100
=> SI = 2872 x 9 /100
=> SI = 25848 /100
=> SI = 258.48
New Balance = Principal + Simple Interest
=> New Balance = 359 + 258.48
=> New Balance = 617.48
Ship A and Ship B are 120 km apart when they pick up a distress call from another boat. Ship B estimates that they are 70 km away from the distress call. They also notice that the angle between the line from ship B to ship A and the line from ship A to the distress call is 28°. What are the two possible distances, to the nearest TENTH of a km, from ship A to the boat?
Answers
Answer:
147.5 km and 64.4 km
Step-by-step explanation:
a=120 km
b=70 km
β=28 degrees ( ∘)
b^2=(a^2)+(c^2)−2ac*cosβ
70^2 =(120^2 )+(c^2)−2⋅ 120⋅ c⋅ cos(28∘ )
(c^2 ) −211.907c+9500=0
note p, q, and r are replacement variables in the Pythagorean theorem since a, b, and c are already in use
p=1;q=−211.907;r=9500
D=(q^2 ) −4pr=(211.907^2 )−4⋅1⋅9500=6904.75561996

Select all true statements about the square root of 2.
-It is a real number.
-It is an irrational number.
-It is a rational number.
-It is an integer.
-It is not a real number.
Answers
Answer:
The correct answer choices are:
1) It is a real number
2) It is an irrational number
Step-by-step explanation:
So we have the number:
[tex]\sqrt2[/tex]
First, let's define each of the terms:
Real numbers are all of the irrational and rational numbers. If a number is irrational or rational, then they are a real number. Any number that does not include the imaginary number i is real (you'll learn this eventually. It's actually really interesting!).
Irrational numbers are the numbers that do not terminate nor repeat. Examples include π or √3. Note that numbers like 1/3 which is .3333 is not irrational because they are repeating. π, on the other hand, does not repeat and never ends.
Rational numbers are the numbers that terminate or repeat. They also include the integers, whole numbers, and natural numbers.
So, the √2. First, it's real because it doesn't deal with imaginaries.
Next, use a calculator and calculate √2. We can see that it is about 1.41423562... This number does not repeat. And it does not terminate (end). In other words, √2 is a irrational numbers.
Since it is irrational, it cannot be rational. Since it's not rational, it cannot be an integer, whole number, or a natural number.
Therefore, the correct answer choices are:
1) It is a real number
2) It is an irrational number
Answer:
[tex]\Large \boxed{\mathrm{It \ is \ a \ real \ number.}} \\ \\ \Large \boxed{\mathrm{It \ is \ an \ irrational \ number.}}[/tex]
Step-by-step explanation:
[tex]\sqrt{2}[/tex]
Real numbers includes all the rational and irrational numbers.
Not real numbers include all the imaginary numbers.
Integers includes all whole numbers that are negative, positive, or zero.
Rational numbers can be expressed as the quotient of two integers.
Irrational numbers cannot be expressed as the quotient of two integers.
[tex]\sqrt{2}= 1.41421356237......[/tex]
The result of square root of 2 keeps going on.
It cannot be expressed as the quotient of two integers.
Therefore, the square root of 2 is an irrational number.
It is a real number since it is an irrational number.
Binomial (x – 6) and trinomial (–2x2 + x + 9) are the factors of which of the following polynomials?
Answers
Answer:
The polynomial is -2x³ + 13x² + 3x - 54.
Step-by-step explanation:
The binomial expression is: (x - 6)
The trinomial expression is: (-2x² + x + 9)
Multiply the two expressions to determine the resulting polynomial as follows:
[tex](x-6)(-2x^{2}+x+9)=x(-2x^{2}+x+9)-6(-2x^{2}+x+9)[/tex]
[tex]=-2x^{3}+x^{2}+9x+12x^{2}-6x-54\\=-2x^{3}+13x^{2}+3x-54[/tex]
Thus, the polynomial is -2x³ + 13x² + 3x - 54.

Tyrone claims that the first step to simplfy this expression is to raise the numerator and denominator to the third power. Alisha claims that the first step to simplfy is to apply the qoutient of powers. Who is correct? Explain.
Answers
Answer:
Alisha's approach is simpler and less complicated
Step-by-step explanation:
Given:
(m^2*n^-3) / (m^6*n^-1)
Tyrone's approach.
(m^2*n^-3) / (m^6*n^-1)
(m^2*n^-3)^3 / (m^6*n^-1)^3
You can find the cube root of both the numerator and denominator in order to eliminate the third power
3√((m^2*n^-3)^3 / 3√(m^6*n^-1)^3
This will take us back to the original expression
(m^2*n^-3) / (m^6*n^-1)
= m^(2-6)*n^(-3+1)
= m^-4*n^-2
= 1/(m^4*n^2)
Alisha's approach.
(m^2*n^-3)/(m^6*n^-1)
= m^(2-6)*n^(-3+1)
= m^-4*n^-2
= 1/(m^4*n^2)
The approach of both of them are correct, however, Tyrone's approach will make the expression more complicated but they would still arrive at the same answer. 1/(m^4*n^2)

How much money did the Emdin family spend on their meal?
Answers
Answer:
The Emdin family spent $19.5 on their meal
Step-by-step explanation:
Let
Juice boxes=x
BBQ sandwiches =y
The Meyers family purchased 4 juice boxes and 2 BBQ sandwiches for $16.
4x+2y=16
The Kaplinsky purchased 4 juice boxes and 3 BBQ sandwiches for $21.
4x+3y=21
4x+2y=16 (1)
4x+3y=21 (2)
Subtract (1) from 2
3y-2y=21-16
y=5
Substitute the value of y into (1)
4x+2y=16
4x+2(5)=16
4x+10=16
4x=16-10
4x=6
Divide both sides by 4
x=6/4
=1 2/4
=1 1/2
x=1.5
The Emdin family showed up late to the county fair and purchased 3 juice boxes and 3 BBQ sandwiches
3x+3y
Substitute the values of x and y
= 3(1.5)+3(5)
= 4.5 + 15
= $19.5

If the area of a circular pool is 300 square yards, what is its radius?
Answers
Answer:
radius = 9.77 yardsStep-by-step explanation:
Since the pool is circular
Area of a circle = πr²
where
r is the radius
From the question
Area = 300 square yards
To find the radius substitute the value of the area into the above formula and solve for the radius
That's
300 = πr²
Divide both sides by π
We have
[tex] {r}^{2} = \frac{300}{\pi} [/tex]
Find the square root of both sides
That's
[tex]r = \sqrt{ \frac{300}{\pi} } [/tex]
r = 9.7720502
We have the final answer as
radius = 9.77 yardsHope this helps you

Since angle A = Angle E
Therefore, Angle B (=x) = Angle D
B = X
D = 66
By replacement B = X = D = 66
So, B = 66
Answer is (A)
-------------
Second question’s answer:
Since Angle F = 63 & Angle C = (3X + 3)
Therefore, Angle F = Angle C
63 = (3X + 3)
Add (-3) into each side
63 + (-3) = (3X + 3) -3
3x + -3x = 0
63 + -3x = 3 + 0
63 + -3x = 3
Now, Add '-63' to each side of the equation
63 + -63 + -3x = 3 + -63
63 + -63 = 0
0 + -3x = 3 + -63
-3x = 3 + -63
3 + -63 = -60
-3x = -60
Divide each side by '-3'
x = 20
So, X angle value is 20 (X=20)
The answer is (C)

Step-by-step explanation:
Solve for x:
2 x^2 - 8 x - 24 = 0
The left hand side factors into a product with three terms:
2 (x - 6) (x + 2) = 0
Divide both sides by 2:
(x - 6) (x + 2) = 0
Split into two equations:
x - 6 = 0 or x + 2 = 0
Add 6 to both sides:
x = 6 or x + 2 = 0
Subtract 2 from both sides:
