Answer:

Top left

Step-by-step explanation:

If an x value (domain) leads to more than one y-value (range), it is not a function. In other words, if each input value leads to only one output value, it is a function. It's still a function if the y-value leads to multiple x-values.

Answer:

C

Step-by-step explanation:

The slope is 3. A perpendicular line has the complete opposite of the other. So if it is -1/3 slope for one line, the perpendicular line would be 3/1 which simplifies to 3. Hope this helps!

Answer: B is the correct answer

Step-by-step explanation: when your symbol is less than it will go to the left and when it is is greater than it will go to the right, and since the symbol is greater than or equal to the circle thingy will be filled in. So, B is the correct answer.

Answer:

x = 56 degrees, y = 32 degrees

Step-by-step explanation:

The Isosceles Triangle Theorem (ITT) tells us that if there are two sides of a triangle that are congruent, then the base angles of this triangle are congruent (angles opposite the congruent sides).

Let's focus on Triangle PQS first. We have the acute angle 68° and want to find x. Due to the ITT, we know that the other missing angle must also equal x.

Therefore, we can create an equation where the interior angles of Triangle PQS will add up to 180, because all interior angle measures of a triangle add up to 180 degrees.

Combine like terms.

Subtract 68 from both sides of the equation.

Divide both sides the equation by 2.

We have found that x = 56 degrees, and now we need to find y. We can do so by using the information we have already found. Since we have found the two angles x of Triangle PQS, we can find ∠QSR in Triangle QSR by using the idea that angles that make up a straight line must add up to 180 degrees.

Therefore:

We have found that ∠PSQ = 56, so substitute this value into the equation.

Subtract 56 from both sides of the equation.

Now we can use the fact that all interior angle measurements of a triangle add up to 180 degrees, and since we have 2 angle measures of Triangle QSR, we can create an equation to solve for y.

Combine like terms.

Subtract 148 from both sides of the equation.

We have found x = 56 degrees and y = 32 degrees.

(a) Hypergeometric distribution

(b) 0.785384...

Step-by-step explanation:

(a) looking at the question, we see that [tex]X = \in \{0, ... , 10 \}[/tex], suppose Evans studied s key terms, this implies that he has not studied 100 - s key terms. Suppose [tex]k = \in \{0, ... , 10 \}[/tex] if X = k, then k out of the s key terms he had studied appeared. But 10 - k out of 100 - s key terms he hasn't studied appeared. Thus X is an Hypergeometric distribution, X~HGeom(s, 100 - s, 10) with PMF:

Answer:

The following classification is found:

[tex](0.2, 6)[/tex] - Absolute minimum

[tex](-0.2, 10)[/tex] - Absolute maximum

Step-by-step explanation:

Let be [tex]f(x) = 125\cdot x^{3}-15\cdot x + 8[/tex], we need to find first and second derivatives of this expression at first:

First derivative

[tex]f'(x) = 375\cdot x^{2}-15[/tex] (Eq. 1)

Second derivative

[tex]f''(x) = 750\cdot x[/tex] (Eq. 2)

Critical points are points that equals first derivative to zero and that may be maxima or minima. That is:

[tex]375\cdot x^{2} -15 = 0[/tex]

[tex]x = \pm \sqrt{\frac{15}{375} }[/tex]

Which leads to the following critical points:

[tex]x_{1}\approx 0.2[/tex] and [tex]x_{2} \approx -0.2[/tex]

Now we evaluate each result in second derivative expression:

[tex]f''(x_{1}) = 750\cdot (0.2)[/tex]

[tex]f''(x_{1})=150[/tex] (Absolute minimum)

[tex]f''(x_{2})= 750\cdot (-0.2)[/tex]

[tex]f''(x_{2}) = -150[/tex] (Absolute maximum)

Lastly we evaluate the function at each critical point:

[tex]f(x_{1})= 125\cdot (0.2)^{3}-15\cdot (0.2)+8[/tex]

[tex]f(x_{1})= 6[/tex]

[tex]f(x_{2})= 125\cdot (-0.2)^{3}-15\cdot (-0.2)+8[/tex]

[tex]f(x_{2}) = 10[/tex]

And the following classification is found:

[tex](0.2, 6)[/tex] - Absolute minimum

[tex](-0.2, 10)[/tex] - Absolute maximum

study writers of pagan Rome

Step-by-step explanation:

Petrarch believed Christian scholars should study writers of pagan Rome. Option (b) is correct.

A writer is someone who writes books, articles, stories, etc., sometimes as a job or a vocation.

Francesco Petrarca, often known as Petrarch, was an Italian philosopher, poet, and one of the first Humanists. He lived from July 20, 1304, to July 19, 1374. The 14th-century Renaissance is frequently regarded with having started as a result of Petrarch's rediscovery of Cicero's letters. Humanism is frequently credited with having its roots in Petrarch. During the Renaissance, Petrarch's sonnets were appreciated, emulated, and used as a template for lyrical poetry all over Europe. Based on Petrarch's writings, Pietro Bembo developed the framework for the modern Italian language in the 16th century.

Therefore, Option (b) is correct. Petrarch believed Christian scholars should study writers of pagan Rome.

Answer:

The wood was cut approximately 8679 years ago.

Step-by-step explanation:

At first we assume that examination occured in 2020. The decay of radioactive isotopes are represented by the following ordinary differential equation:

[tex]\frac{dm}{dt} = -\frac{m}{\tau}[/tex] (Eq. 1)

Where:

[tex]\frac{dm}{dt}[/tex] - First derivative of mass in time, measured in miligrams per year.

[tex]\tau[/tex] - Time constant, measured in years.

[tex]m[/tex] - Mass of the radioactive isotope, measured in miligrams.

Now we obtain the solution of this differential equation:

[tex]\int {\frac{dm}{m} } = -\frac{1}{\tau}\int dt[/tex]

[tex]\ln m = -\frac{1}{\tau} + C[/tex]

[tex]m(t) = m_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (Eq. 2)

Where:

[tex]m_{o}[/tex] - Initial mass of isotope, measured in miligrams.

[tex]t[/tex] - Time, measured in years.

And time is cleared within the equation:

[tex]t = -\tau \cdot \ln \left[\frac{m(t)}{m_{o}} \right][/tex]

Then, time constant can be found as a function of half-life:

[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (Eq. 3)

If we know that [tex]t_{1/2} = 5730\,yr[/tex] and [tex]\frac{m(t)}{m_{o}} = 0.35[/tex], then:

[tex]\tau = \frac{5730\,yr}{\ln 2}[/tex]

[tex]\tau \approx 8266.643\,yr[/tex]

[tex]t = -(8266.643\,yr)\cdot \ln 0.35[/tex]

[tex]t \approx 8678.505\,yr[/tex]

Answer:

The magnitude of the velocity will be 60 m/s.

The distance covered is 3,600 m

Step-by-step explanation:

Constant Acceleration Motion

It's known as a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.

If a is the constant acceleration, vo is the initial speed, vf the final speed, and t the time, the following relation applies:

[tex]v_f=v_o+at[/tex]

The distance traveled by the object is calculated as:

[tex]\displaystyle x=v_o.t+\frac{a.t^2}{2}[/tex]

The bus starts from rest, i.e. vo=0, the acceleration is a=0.5 m/s^2. The magnitude of the velocity at t=2 minutes = 120 seconds is:

[tex]v_f=0+0.5\cdot 120=60 \ m/s[/tex]

The magnitude of the velocity will be 60 m/s.

The distance covered during that time is:

[tex]\displaystyle x=0+\frac{0.5\cdot 120^2}{2}[/tex]

[tex]\displaystyle x=\frac{7,200}{2}[/tex]

x = 3,600 m

The distance covered is 3,600 m

Answer:

[tex]y=-2^{(x+2)}+1[/tex]

Step-by-step explanation:

Equation of the parent function of the graph attached is,

y = [tex]2^{x}[/tex]

Let the equation of the transformed function function shown in the graph be,

y = a(2ˣ) + b

Now we will find the values of a and b by substituting the points lying on the curve.

For (-2, 0),

0 = a(2⁻²) + b

[tex]\frac{a}{4}+b=0[/tex] ------(1)

For (0, -3),

-3 = a(2⁰) + b

a + b = -3 --------(2)

Subtract equation (1) from equation (2),

(a + b) - ([tex]\frac{a}{4}+b[/tex]) = 0 + 3

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

a = -4

From equation (2),

-4 + b = -3

b = 1

Therefore, equation of the transformed function will be,

[tex]y=-4(2^x)+1[/tex]

[tex]y=-2^{2}(2^x)+1[/tex]

[tex]y=-2^{(x+2)}+1[/tex]

Graph transformation is the process by which an existing graph is modified to produce a variation of the proceeding graph.

Equation of transformed graph is, [tex]y=-2^{x+2}+1[/tex]

Here,  equation of original graph is given, [tex]y=2^{x}[/tex]

Let us consider, equation of transformed graph is,  [tex]y=m(2^{x} )+n[/tex]

Since, given graph passing through points (-2,0) and (0,-3)

Substituting above points into equation.

We get two equation,

                                      m +4n = 0

                                     m + n = -3

After solving, we get   m= -4 and  n = 1

So, equation becomes  [tex]y=-2^{x+2}+1[/tex]
