Answers

Answer:

Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Both the first and second signs are negative,

Let α and β are the roots of the ,

then, we know that the relationship between the zeroes and coefficients of quadratic equations:

Since the product of roots is positive.

So, the signs of the factors will be one positive and one negative.

Hence, Option 'D' is correct.

Consider the parabola given by the equation: y = 1x^2 - 12x + 27

A) the vertex = (_,_)

B) the y-intercept is the point (0,_)

C) find the two values of x that corresponds to the x intercepts of the parabola and write them as a list separated by commas:
X= ___

Answers

Answer:

vertex: (6, -9)

y intercept: (0, 27)

X = 3, 9

Step-by-step explanation:

Finding Vertex (Part A)

Consider the formula -b/2a. This formula gives you the x-coordinate of the vertex.

y = 1x^2 - 12x + 27

a = 1

b= -12

c =27

-b/2a = - (-12)/2(1) = 12/2 = 6 (x-coordinate of vertex)

When solving for the y-coordinate of the vertex you will need to substitute your 'x" back into the equation.

y = 1(6)^2 - 12(6) + 27

y = 36 - 72 + 27 = -9 (y-coordinate of vertex)

--------------------------------------------------------------------------

Y- Intercept (Part B)

When looking for the y-intercept your "x" must always be 0.

Substitute 0 in every "x" in equation.

y = 1(0)^2 - 12(0) + 27

y = 27

y intercept: (0, 27)

------------------------------------------------------------------------------

X- Intercepts (Part C)

To find the values of "x" factor.

y = 1x^2 - 12x + 27

0 = 1x^2 - 12x + 27

0 = (x  - 3     )(x   -  9 )

(x-3) = 0             (x-9) = 0

x = 3                    x = 9

Find an equation of the tangent line to the curve y = 10/(1 + e^-x) at the point (0,5)

Answers

Compute the derivative, dy/dx (use the chain rule):

y = 10/(1 + e ⁻ˣ) = 10 (1 + e ⁻ˣ)⁻¹

===>   dy/dx = -10 (1 + e ⁻ˣ)⁻² (-e ⁻ˣ) = 10e ⁻ˣ/(1 + e ⁻ˣ)²

Evaluate the derivative for x = 0 to get the slope of the tangent to the curve at (0, 5) :

dy/dx (0) = 10e ⁰/(1 + e ⁰)² = 10/(1 + 1)² = 10/4 = 5/2

Use the point-slope formula to get the equation of the tangent line:

y - 5 = 5/2 (x - 0)

===>   y = 5/2 x + 5

The ratio of girls to total students in math class is 13 to 20. Using this ratio, how many boys are in math class?​

Answers

9514 1404 393

Answer:

  girls : boys = 13 : 7

  7 boys in the math class

Step-by-step explanation:

We assume that the number of boys is the total number of students less the number of girls. In ratio units, that is ...

  girls : boys = girls : (total - girls) = 13 : (20 -13)

  girls : boys = 13 : 7

There are 7 boys in the math class.

_____

Additional comment

We are only told the ratio, not any actual numbers. In order to answer the question, we must assume a total for the number of students in the class. It is convenient to assume that total is 20. There is nothing in the problem statement to indicate it is not some multiple of 20. The number of boys will be 7/20 of the total number of students in the math class.

Which statement about this mapping is true?

The mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.

The mapping represents y as a function of x, because each x-value is related to exactly one y-value.

The mapping does not represent y as a function of x, because there are more x-values than related y-values.

The mapping represents y as a function of x, because each y-value is related to exactly one x-value.

Answers

Answer:

The mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.

Step-by-step explanation:

See it's not a function

Because In a function every c value has a unique y value.Here there is 4 values for one x .So it's a relation

The statement which is true about this mapping is the mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

WE have been given a domain figure.

We can see that the input values has more than one output values.

therefore, it cannot be a function Because in a function every input value has a unique y value.

Here there is 4 values for one x input.

x = 3

y = 2, 4, 5, 6

So it's a relation

Hence, the statement which is true about this mapping is the mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.

Please help! Suppose f(x)=-8x^7 +8x-6

then f(-x)=________

Answers

Answer:

f(-x) = 8x⁷ - 8x - 6

Step-by-step explanation:

f(x) = -8x⁷ + 8x - 6

To find f(-x), we'll need to plug in -x instead of x.

f(x) = -8x⁷ + 8x - 6

f(-x) = -8(-x)⁷ + 8(-x) - 6

f(-x) = 8x⁷ - 8x - 6

evaluate -(2-^6)(2^3)

Answers

Answer:

The answer = -512

Step-by-step explanation:

To find -(2-^6)(2^3)

We have that -(2-^6) = {-(-2*-2*-2*-2*-2*-2)}=

-(64) which is -64

For (2^3) = (2*2*2) =8

Therefore -(2-^6)(2^) = (-64)(8)

which is = -512

So therefore -(2-^6)(2^3) = -512
