Answer:

[tex]y = 3x - 6[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (4,6)[/tex]

[tex](x_2,y_2) = (3,3)[/tex]

Required

Equation in slope intercept

First, calculate the slope.

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{3-6}{3-4}[/tex]

[tex]m = \frac{-3}{-1}[/tex]

[tex]m = 3[/tex]

The equation is:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = 3(x - 4) +6[/tex]

[tex]y = 3x - 12+6[/tex]

[tex]y = 3x - 6[/tex]

The statement that is true for the retangular doors and windows is the area of the door is 3.24 times the area of the window.

The perimeter of a rectangle is the sum of the whole side of the rectangle.

Therefore,

perimeter of a rectangle = 2l + 2w

where

Therefore, each dimension of the door is 1.8 times the dimension of the window.

Hence,

let

the width of the window = x

the length of the window = y

Therefore,

perimeter = 2(x+ y)

The perimeter of the doors will be as follows:

perimeter of the doors = 2(1.8(x) + 1.8(y))

perimeter of the doors = 3.6(x + y)

area = lw

Therefore,

area of window = xy

area of doors = 1.8x(1.8y)

area of doors =  3.24xy

Answer:

A (x+y=2)

Step-by-step explanation:

in order to see the slope value and to turn the equation into the slope-intercept form (y=mx+b). Basically we just solve for y and look at the coefficient of x. Then to see the value of the x-intercept we need to give y zero and then solve for x.

a) x+y=2

y=-x+2 (slope is -1)

when y=0 ; 0=-x+2 ; x=2 (x-int=2)

b) x-y=-2

y=x+2 (slope≠-1, it is +1 so this not the answer)

c) x+y=-2

y=-x-2 (slope is -1)

when y=0 ; 0=-x-2 ; x=-2 (x-int≠2 it is -2 so this not the answer)

d) x-y=2

y=x-2 (slope≠-1, it is +1 so this not the answer)

the answer is A (x+y=2)

Answer:

x + y = 2.

Step-by-step explanation:

Using the standard form

y = mx + b

the equation is

y = -1x + b  

Now as the x intercept is (2, 0),  x = 2 when y = 0 so:

0 = -1(2) + b

2 = b

b = 2

so we have

y = -x + 2

y + x = 2.

Answer:

d

Step-by-step explanation:

From the above, it can be seen that the nature of polynomial functions is dependent on its degree. Higher the degree of any polynomial function, then higher is its growth. A function which grows faster than a polynomial function is y = f(x) = ax, where a>1. Thus, for any of the positive integers n the function f (x) is said to grow faster than that of fn(x).

Thus, the exponential function having base greater than 1, i.e., a > 1 is defined as y = f(x) = ax. The domain of exponential function will be the set of entire real numbers R and the range are said to be the set of all the positive real numbers.

It must be noted that exponential function is increasing and the point (0, 1) always lies on the graph of an exponential function. Also, it is very close to zero if the value of x is mostly negative.

Exponential function having base 10 is known as a common exponential function. Consider the following series:

Derivative of logarithmic and exponential function 5

The value of this series lies between 2 & 3. It is represented by e. Keeping e as base the function, we get y = ex, which is a very important function in mathematics known as a natural exponential function.

For a > 1, the logarithm of b to base a is x if ax = b. Thus, loga b = x if ax = b. This function is known as logarithmic function.

Derivative of logarithmic and exponential function 2

For base a = 10, this function is known as common logarithm and for the base a = e, it is known as natural logarithm denoted by ln x. Following are some of the important observations regarding logarithmic functions which have a base a>1.

   The domain of log function consists of positive real numbers only, as we cannot interpret the meaning of log functions for negative values.

   For the log function, though the domain is only the set of positive real numbers, the range is set of all real values, i.e. R

   When we plot the graph of log functions and move from left to right, the functions show increasing behaviour.

   The graph of log function never cuts x-axis or y-axis, though it seems to tend towards them.

Derivative of logarithmic and exponential function 3

   Logap = α, logbp = β and logba = µ, then aα = p, bβ = p and bµ = a

   Logbpq = Logbp + Logbq

   Logbpy = ylogbp

   Logb (p/q) = logbp – logbq

Exponential Function Derivative

Let us now focus on the derivative of exponential functions.

The derivative of ex with respect to x is ex, i.e. d(ex)/dx = ex

It is noted that the exponential function f(x) =ex  has a special property. It means that the derivative of the function is the function itself.

(i.e) f ‘(x) = ex = f(x)

Exponential Function Properties

The exponential graph of a function represents the exponential function properties.

Let us consider the exponential function, y=2x

The graph of function y=2x is shown below. First, the property of the exponential function graph when the base is greater than 1.

Exponential Functions

Exponential Function Graph for y=2x

The graph passes through the point (0,1).

   The domain is all real numbers

   The range is y>0

   The graph is increasing

   The graph is asymptotic to the x-axis as x approaches negative infinity

   The graph increases without bound as x approaches positive infinity

   The graph is continuous

   The graph is smooth

Exponential Functions

Exponential Function Graph y=2-x

The graph of function y=2-x is shown above. The properties of the exponential function and its graph when the base is between 0 and 1 are given.

   The line passes through the point (0,1)

   The domain includes all real numbers

   The range is of y>0

   It forms a decreasing graph

   The line in the graph above is asymptotic to the x-axis as x approaches positive infinity

   The line increases without bound as x approaches negative infinity

   It is a continuous graph

   It forms a smooth graph

Exponential Function Rules

Some important exponential rules are given below:

If a>0, and  b>0, the following hold true for all the real numbers x and y:

       ax ay = ax+y

       ax/ay = ax-y

       (ax)y = axy

       axbx=(ab)x

       (a/b)x= ax/bx

       a0=1

       a-x= 1/ ax

Exponential Functions Examples

The examples of exponential functions are:

   f(x) = 2x

   f(x) = 1/ 2x = 2-x

   f(x) = 2x+3

   f(x) = 0.5x

Solved problem

Question:

Simplify the exponential equation 2x-2x+1

Solution:

Given exponential equation: 2x-2x+1

By using the property: ax ay = ax+y

Hence, 2x+1 can be written as 2x. 2

Thus the given equation is written as:

2x-2x+1 =2x-2x. 2

Now, factor out the term 2x

2x-2x+1 =2x-2x. 2 = 2x(1-2)

2x-2x+1 = 2x(-1)

2x-2x+1 = – 2x

Answer: (b)- 41.57

Step-by-step explanation:

Given

Dimension of Parallelogram is

[tex]\text{base b=8\ units}[/tex]

[tex]\text{length l=6 units}[/tex]

The area of a parallelogram is given by

[tex]\Rightarrow A=b\times h[/tex]

we need height for the area

From the figure, we can write

[tex]\Rightarrow \cos 30^{\circ}=\dfrac{AB}{6}\\\\\Rightarrow AB=6\cos 30^{\circ}=5.196[/tex]

and AB is the height of the parallelogram

[tex]\Rightarrow A=8\times 5.196=41.569\approx 41.57[/tex]

Answer:

y=a+be^(-1/4t)

Step-by-step explanation:

We can solve the characteristic equation, 4r^2+r=0 to help.

Factor:

r(4r+1)=0

This implies r=0 or 4r+1=0.

The second equation can be solved by subtracting 1 on both sides and then dividing boths sides by 4 like so:

4r+1=0

4r+1-1=0-1

4r=-1

4r/4=-1/4

r=-1/4

So r=0 and r=-1/4 which means the general solution is y=ae^(0t)+be^(-1/4t)

Simplifying gives y=a+be^(-1/4t) since e^0=1.

Let's check our solution.

y=a+be^(-1/4t)

y'=0+-1/4be^(-1/4t)

y''=0+1/16be^(-1/4t)

Plug in:

4y''+y'=0

4*1/16be^(-1/4t)+-1/4be^(-1/4t)=0

1/4be^(-1/4t)+-1/4be^(-1/4t)=0

0=0 is a true equation so the solution has been verified.
