The y-intercept represents the initial temperature, and the rate of change gives how the temperature changes per minute.

So the correct options are A and D.

Here we have a relation that shows how the temperature changes as a function of time.

So if F(x) is the temperature and x is the time, the y-intercept is given by:

F(0)

So the y-intercept is the initial temperature, the correct option is A.

And the rate of change tells us how the temperature changes as the time passes, so we can define the rate as "the change in temperature per minute" like on option D.

Let length of vector is 5 then the vector in the direction of  ⟨−3,−1,5⟩ will be ⟨−15/√35,−5/√35,25/√35⟩.

What is a Vector?

Vectors, in Maths, are objects which have both, magnitude and direction. Magnitude defines the size of the vector. It is represented by a line with an arrow, where the length of the line is the magnitude of the vector and the arrow shows the direction. It is also known as Euclidean vector or Geometric vector or Spatial vector or simply “vector“.

Two vectors are said to equal if their magnitude and direction are the same. It plays an important role in Mathematics, Physics as well as in Engineering. According to vector algebra, a vector can be added to another vector, head to tail. The order of addition of two vectors does not matter, because the result will be the same.

Now,

The idea is based on a concept of scaling and similarity.

Any vector that "has the same direction" as

⟨−3,−1,5⟩

has all the coordinates proportional to this given vector and, therefore, can be described by coordinates

⟨−3f,−1f,5f⟩

where f is a scaling factor.

All we need now is to find a scaling factor that leads to a vector with the length 5

The length of a vector with coordinates

⟨−3f,−1f,5f⟩

equals to√9f^2+f^2+25f^2=√35f

So, if we want the length to be equal to 5, we should choose

f=5/√35

Hence,

          The coordinates of a vector with the same direction as  ⟨−3,−1,5⟩ but with the length 5 will be ⟨−15/√35,−5/√35,25/√35⟩.

The value of the function (g o f) (x) = 12x + 49.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).

Given that the value of f(x) = x + 4 and g(x) = 12x + 1.

The value of (g o f)(x) is:

g(x) = 12x + 1

Substitute the value of f(x) in x for the function of g(x):

(g o f) (x) = 12(x + 4) + 1

(g o f) (x) = 12x + 48 +1

(g o f) (x) = 12x + 49

ax²+bx+c=0, with a not, equals to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.

Given,  the function f(x)= -x²- 6x - 8 Since the given equation is a parabola.

Rewrite the given equation in the vertex form.

f(x) = -x²- 6x - 8

f(x) = -(x² + 6x +8)

f(x) = -(x² + 2 * 3 *x + 9 -1)

f(x) = -(x +3)² +1

Compare this with the general equation of the vertex form

y = a(x - h)²  + k

We get,

a = -1

h = -3

k = 1

Thus the vertex of the given parabola will be (-3, 1)

Since the general form of the focus of the parabola (h, k +p)

Where,

k = 1/4a

k = -1/4

Thus, the coordinates of the focus of the parabola will be (-3, 3/4)

Since the equation of symmetry will be the equation of the line that passes through the points focus and vertex.

Answer:

The answer is 1000000.

The solution is Option A.

The value of the equation is x = -13/15 and x = 0

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

15x² + 13x = 0   be equation (1)

On simplifying the equation , we get

Subtracting 13x on both sides of the equation , we get

15x² = -13x

Divide by x on both sides of the equation , we get

15x = -13

Divide by 15 on both sides of the equation , we get

x = - ( 13/15 )

So , when x = 0

0 = 0

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

x = -13 ± √ ( 169 - 4 ( 15 ) ( 0 ) ) / 2 ( 15 )

x = -13 ± √ ( 169 - 0 ) / 30

x = ( -13 ± 13 ) / 30

So , we have 2 solutions to x ,

x = ( -13 - 13 ) / 30

x = -26 / 30

Using Laplace Transformation, the initial value problem y" - 2y' + y = 0 , y(0) = 1 , y'(0) = 2 is y(t) = e^t + te^t.

The differential equation is y" - 2y' + y = 0 and y(0) = 1 , y'(0) = 2

As we know that the Laplace Equation is:

[tex]L(y^n(t)) = s^nf(s) - s^{n-1}y(0) - s^{n-2}y'(0)-\dots-sy^{n-2}(0)-y^{n-1}(0)[/tex]

Now applying the Laplace Transformation in the differential equation

L(y") - 2L(y') + L(y) = 0........(1)

Now finding the value of L(y") using the equation

L(y") = s^2f(s) - s(1) - 2

L(y") = s^2f(s) - s - 2

Now finding the value of L(y') using the equation

L(y') = sf(s) - 1

Now finding the value of L(y) using the equation

L(y) = f(s)

Now putting the values in the equation 1

s^2f(s) - s - 2 - 2(sf(s) - 1) + f(s) = 0

Now solving

s^2f(s) - s - 2 - 2sf(s) + 2 + f(s) = 0

s^2f(s) - s - 2sf(s) + f(s) = 0

Taking common f(s) in term terms of f(s)

(s^2 - 2s + 1)f(s) - s = 0

Add s on both side, we get

(s^2 - 2s + 1)f(s) = s

We can write (s^2 - 2s + 1) as (s - 1)^2

(s - 1)^2f(s) = s

Divide by (s - 1)^2 on both side, we get

f(s) = s/(s - 1)^2

The inverse Laplace of f(s) = s/(s - 1)^2 is

Equation 1: 7y = 2x - 47  ==> add 2x on both sides

Equation 2: y = 9x + 2

7 * (y = 9x + 2)

Equation 3: 7y = 63x + 14

Equation 1: 7y = 2x - 47

Subtract equation 1 from equation 3:

  7y = 63x + 14

- (7y = 2x - 47)

7y-7y = 63x-2x + 14-(-47)

0 = 61x + 14 + 47

0 = 61x + 61  ==> solve for x

-61 = 61x  ==> subtract 61 on both sides to isolate x

x = -1

Now solve for y

y = 9(-1) + 2  ==> plugin -1 for x in y=9x+2`

y = -9 + 2  ==> simplify

y = -7
