Which of the following represents a line with a slope of 4, x-intercept of (2, 0) and a y-intercept of (0, -8)?

The relationship between lines KO and K’O’ is given as Line K'O' = 5*line KO

Transformation is the movement of a point from its initial point to a new location. Types of transformation are reflection, rotation, translation and dilation.

Reflection happens when it is reflected over a line as we see in a mirror. But here the two triangles are not looking as images on  a line.  Hence no reflection

Rotation is keeping the same shape but rotating through a certain angle.

Translation is not right because there is no vertical or horizontal shift to get new triangle.

Dilation is the increase or decrease in size of a figure by a scale factor.

The larger figure was dilated using a scale factor of 5

hence

Line K'O' = 5 * line KO

The relationship between lines KO and K’O’ is given as Line K'O' = 5 * line KO

Answer:

The probability is [tex]P(X < 450 ) = 0.18703[/tex]

Step-by-step explanation:

From the question we are told that

    The mean is  [tex]\mu = \$ 490[/tex]

     The standard deviation is  [tex]\sigma = \$ 45[/tex]

Generally the probability that he/she earns less than $450 a week is mathematically represented as

        [tex]P(X < 450 ) = P(\frac{X - \mu }{\sigma} < \frac{450 - 490}{45} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

          [tex]P(X < 450 ) = P(Z < -0.8889 )[/tex]

From the z table  the area under the normal curve to the left corresponding to    -0.8889  is

         [tex]P(Z < -0.8889 ) = 0.18703[/tex]

=>     [tex]P(X < 450 ) = 0.18703[/tex]

Answer:

Part A)

[tex]f(1)=2, \; f^{-1}(1)=0, \; f^\prime(1)=1.4, \; (f^{-1})^\prime(1)=\frac{10}{7}[/tex]

Part B)

[tex]y=\frac{5}{14}x+\frac{4}{7}[/tex]

Step-by-step explanation:

Please refer to the table of values.

Part A)

A. 1)

We want to find f(1).

According to the table, when x=1, f(x)=2.

Hence, f(1)=2.

A. 2)

We want to find f⁻¹(1).

Notice that when x=0, f(x)=1.

So, f(0)=1.

Then by definition of inverses, f⁻¹(1)=0.

A. 3)

We want to find f’(1).

According to the table, when x=1, f’(x)=1.4.

Hence, f’(1)=1.4.

A. 4)

We will need to do some calculus.

Let g(x) equal to f⁻¹(x). Then by the definition of inverses:

[tex]f(g(x))=x[/tex]

Take the derivative of both sides with respect to x. On the left, this will require the chain rule. Therefore:

[tex]f^\prime(g(x))\cdot g^\prime(x)=1[/tex]

Solve for g’(x):

[tex]g^\prime(x)=\frac{1}{f^\prime(g(x))}[/tex]

Substituting back f⁻¹(x) for g(x) yields:

[tex](f^{-1})^\prime(x)=\frac{1}{f^\prime({f^{-1}(x)})}[/tex]

Therefore:

[tex](f^{-1})^\prime(1)=\frac{1}{f^\prime({f^{-1}(1)})}[/tex]

We already determined previously that f⁻¹(1) is 0. Therefore:

[tex](f^{-1})^\prime(1)=\frac{1}{f^\prime(0)}[/tex]

According to the table, f’(0) is 0.7. So:

[tex](f^{-1})^\prime(1)=\frac{1}{0.7}=\frac{10}{7}[/tex]

Hence, (f⁻¹)’(1)=10/7.

Part B)

We want to find the equation of the tangent line of y=f⁻¹(x) at x=4.

First, let’s determine the points. Since f(2)=4, this means that f⁻¹(4)=2.

Hence, our point is (4, 2).

We will now need to find our slope. This will be the derivative at x=4. Therefore:

[tex](f^{-1})^\prime(4)=\frac{1}{f^\prime({f^{-1}(4)})}[/tex]

We know that f⁻¹(4)=2. So:

[tex](f^{-1})^\prime(4)=\frac{1}{f^\prime(2)}[/tex]

Evaluate:

[tex](f^{-1})^\prime(4)=\frac{1}{f^\prime(2)}=\frac{1}{2.8}=\frac{10}{28}=\frac{5}{14}[/tex]

Now, we can use the point slope form. Our point is (4, 2) and our slope at that point is 5/14.

So:

[tex]y-2=\frac{5}{14}(x-4)[/tex]

Solve for y:

[tex]y-2=\frac{5}{14}x-\frac{20}{14}[/tex]

Adding 2 to both sides yields:

[tex]y=\frac{5}{14}x-\frac{20}{14}+\frac{28}{14}[/tex]

Hence, our equation is:

[tex]y=\frac{5}{14}x+\frac{4}{7}[/tex]

Answer:

A

Step-by-step explanation:

We have the expression:

[tex]-4ab[/tex]

And we want to find its sign given that a>0 and b<0.

Notice that the expression is already negative since we have -4.

a>0 means that a is positive. Therefore, we can ignore it since it won’t do anything.

b<0 means that b is negative. Therefore, we will have two negatives being multiplied together. Hence, this will make a positive.

Therefore, the sign of our expression will be positive.

We can see this with an example. Let a=1 (1>0) and let b=-1 (-1<0). Then:

[tex]-4(1)(-1)=4[/tex]

So, the sign is positive.

Hence, the answer is A.

Answer: the value of the diversity index D is Zero (0)

Step-by-step explanation:

Just as the meaning of diversity index is boldly explained in the question, it is the probability that randomly selected organism from a population are from a different species.

Now if the organisms are all from the same species in a population  then it is impossible to select two organisms from different species.

That is, we can never select two organisms that are not from the same species.

Hence, we cant fulfil or meet the definition of diversity index .

Therefore in this situation the value of our diversity index D will be exactly zero, D = 0.

Step-by-step explanation:

The lines represents the parallel line.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y=5/4x +1 and y=5/4x-7

4y= 5x+ 4 and 4y= 5x-7

Now, [tex]a_1[/tex]= 4, [tex]b_1[/tex]= 5,  [tex]c_1[/tex]= 4

[tex]a_2[/tex]= 4, [tex]b_2[/tex]= 5,  [tex]c_2[/tex]= -7

Now, on comparing the ratio we have

[tex]a_1[/tex]/[tex]a_2[/tex] =  [tex]b_1[/tex]/ [tex]b_2[/tex] ≠  [tex]c_1[/tex]/ [tex]c_2[/tex]

Answer:

Is there suppose to be a graph?

If not, if the original coordinates were (x,y) the new ones will be (y,x)

Step-by-step explanation:

The point C(x , y) is reflected through the line x = y, the coordinates of C is (y, x).

A reflection is "geometric transformation results in mirror image".

According to the question,

The point C(x, y) is reflected through the line X - Y = 0.

Formula to find new coordinates (x-x₁)/a =(y-y₁)/b= -2(ax₁+by₁+c)/(a² + b²)

The point (x, y) = (x₁, y₁) and from the line a = 1, b = - 1,c = 0.

(x-x₁)/1 = -2(x₁ - y₁)/2

x - x₁ +x₁ -y₁ =0

x = y₁.

similarly we get y = y₁

Hence, The point C(x , y) is reflected through the line x = y, the coordinates of C is (y, x).

Answer:

The equation of the line in the form Ax+By=C is [tex]\mathbf{ x+4y=-7}[/tex]

Step-by-step explanation:

We need to write an equation of line that have slope m= -1/4 and point(-7,0)

We would use slope-intercept form: [tex]y=mx+b[/tex]

where m is slope and b is y-intercept.

We are given slope m = -1/4 but we need to find y-intercept

Finding y-intercept

Using the slope m= -1/4 and point(-7,0) we can find y-intercept (b)

[tex]y=mx+b\\0=-\frac{1}{4}(-7)+b\\0= \frac{7}{4}+b\\b=-\frac{7}{4}[/tex]

Now finding the equation of line having slope m= -1/4 and y-intercept b= -7/4

[tex]y=mx+b\\y=-\frac{1}{4}x-\frac{7}{4}[/tex]

Now converting into form Ax+By=C :

[tex]y=-\frac{1}{4}x-\frac{7}{4}\\y=\frac{-x-7}{4}\\4y=-x-7\\x+4y=-7[/tex]

The equation of the line in the form Ax+By=C is [tex]\mathbf{ x+4y=-7}[/tex]
