Consider Points A, B, And C In The Graph. Determine Which Of These Points Is Relative Minima On The Interval
Answer 2

The required minima on the graph in the interval x = -1 and x = -2 is A. Option 4) is correct.

Given that,
A Curve is shown on the graph,
In the interval of x = -1 and x = -2, relative minima is to be determined.

What is a graph?

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.


Since,
A minimum of the curve it that point where the slope of the curve is zero and at that point where the slope is zero the neighboring values must be greater to the point on the curve.

So point a is required minima where the slope is zero and also neighboring values are greater than a

Thus, the required minima on the graph in the interval x = -1 and x = -2 is A. Option 4) is correct.

How to determine the characteristics of rigid transformations by comparing two functions

In this problem we have two functions related to each other because of the existence of rigid transformations. Rigid transformations are transformations applied to geometric loci such that Euclidean distance is conserved at every point of the geometric locus.

Let be f(x) = - 2 · cos (x - 1) + 3, then we use the concept of horizontal translation 4 units in the + x direction:

f'(x) = - 2 · cos (x - 1 + 4) + 3

f'(x) = - 2 · cos (x + 3) + 3     (1)

Now we apply a reflection over the x-axis:

g(x) = - [- 2 · cos (x + 3) + 3]

g(x) = 2 · cos (x + 3) - 3

Therefore, the function g(x) is created by applying an horizontal translation 4 units left and a reflection over the x-axis. (Correct choices: Third option, fifth option)

x-2(x+1)+3(x-2)+2(x-6)=0

Answers

Answer:

x = 5

Step-by-step explanation:

Simplifying the expression:

                       x - 2(x +1) + 3(x -2) + 2(x - 6) = 0

x + (-2)*x  + (-2)*1 + 3*x +3*(-2) + 2*x + 2*(-6) = 0

                            x - 2x -2 + 3x - 6 + 2x - 12 = 0

                          x - 2x + 3x + 2x - 2 - 6 - 12 = 0

Combine like terms. Like terms have same variable with same power.

                                                          4x - 20 = 0

Add 20 to both sides.

                                                                 4x  = 20

Divide both sides by 4

                                                                   x = 20/4

                                                                   x = 5

Answer:

x = 5

Step-by-step explanation:

x  -2(x+1) + 3(x-2) + 2(x-6) =  0

here, we need to distribute the numbers on the outside of the parentheses to the inside numbers.

As you may know, when two numbers are in parentheses, they are to be multiplied--and it is the same idea here.

When we have a number, say 3, multiplied by parentheses, say (x - 2), we multiply all inside numbers by the outside number, which is called distributing.

We know that 3(x) = 3x, and that 3(-2) = -6, so we distribute

3(x  - 2)       to be        3x - 6

let's do that for all of our parentheses:
x  -2(x+1) + 3(x-2) + 2(x-6) =  0

-2( x  + 1 )

-2x   -  2

3(x  - 2)

3x   -  6

2( x  - 6)

2x  - 12

Now, let's rewrite our problem:

x  -2(x+1) + 3(x-2) + 2(x-6) =  0

x     - 2x  - 2    + 3x -6     + 2x - 12    = 0

First, we should combine like terms:

x - 2x  + 3x + 2x          - 2 - 6 - 12    = 0

(x - 2x = -x;  -x + 3x = 2x;  2x + 2x = 4x)

( - 2 - 6 = -8; -8 - 12 = -20

So, we are left with:

4x  -  20 = 0

At this point, we want to get x alone (so that we can find what "x" is)

4x - 20 = 0  

    + 20    + 20       ( add 20 to both sides of the equation to isolate x )  

   4x     =    20

  ÷ 4          ÷ 4           (divide both sides by 4 to find "1"x)

     x  =  5

So, we know that the value of x is 5, or x = 5

Applying the linear pair theorem and the sum of interior angles of hexagon, we have:

Angle 7 = 92°

Angle 1 = 107°

What is the Linear Pair Theorem?

According to the linear pair theorem/postulate, when two angles lie on a straight line, the sum of their measures equals 180 degrees.

Angle 7 lie on a straight line with 88°, therefore, applying the linear pair theorem, we have:

Angle 7 + 88 = 180

Subtract both sides by 88

Angle 7 + 88 - 88 = 180 - 88

Angle 7 = 92°

Also, using the linear pair theorem, we have:

Angle 5 = 180 - 64

Angle 5 = 116°

Angle 3 = 180 - 57

Angle 3 = 123°

Sum of interior angles of hexagon equals 720°, therefore:

Angle 1 + angle 3 + angle 5 + angle 7 + 118 + 164 = 720°

Plug in the known values

Angle 1 + 123 + 116 + 92 + 118 + 164 = 720

Angle 1 + 613 = 720

Subtract both sides by 613

Angle 1 + 613 - 613 = 720 - 613

Angle 1 = 107°

What is the net force acting on the crate? 352 n to the left 176 n to the left 528 n to the right 440 n to the right

Answers

The net force acting on the crate is the sum of all the forces acting in the different directions on the crate, which is 176 N to the left.

What is net force?

The net force is defined as the sum of all the forces acting on an object.

From the figure given that,

Upward force = 440 N

Downward force = - 440 N

Rightward force = 176 N

Leftward Force = - 352 N

The net vertical force acting on the crate = Upward force + Downward force

                                                                       =  440 N + (-440 N)

                                                                       = 0 N

The net horizontal force acting on the crate = Rightward force + Leftward force

                                                                       =176 N + (- 352 N)

                                                                       = - 176 N

The formula C=59(F−32), where F≥−459.67 expresses the Celsius temperature C as a function of Fahrenheit temperature F.
1. Find the formula for the inverse function.
Answer: C^−1(F)=
9F/5+32 (I'm right about this one)
2. What is the domain of the inverse function C^−1 ?
Answer (in interval notation):(for some reason it keep telling me wrong :( )

Answers

Answer:

[tex]\textsf{1.} \quad C^{-1}(F)=\dfrac{9}{5}F+32[/tex]

2.   [-273.15, ∞)

Step-by-step explanation:

Given:

[tex]C=\dfrac{5}{9}(F-32), \quad \text{where }F \geq -459.67[/tex]

To find the inverse of the given function, make F the subject:

[tex]\begin{aligned}C & =\dfrac{5}{9}(F-32)\\\implies \dfrac{9}{5}C & =F-32\\\implies F & = \dfrac{9}{5}C+32 \end{aligned}[/tex]

[tex]\textsf{Replace the } F \textsf{ with }C^{-1}(F)\textsf{ and the }C \textsf{ with } F:[/tex] :

[tex]\implies C^{-1}(F)=\dfrac{9}{5}F+32[/tex]

Domain: set of all possible input values (x-values)

Range: set of all possible output values (y-values)

The given domain of the function C(F) is F ≥ -459.67

Therefore, the minimum value of the function is:

[tex]\implies C(-459.67)=\dffrac{5}{9}(-459.67-32)=-273.15[/tex]

This means the range of the function C(F) is C(F) ≥ -273.15

The domain of the inverse function is the range of the function.

Therefore, the domain of the inverse function in interval notation is:  [-273.15, ∞)

Answer: -273.15

Tumbleweed, commonly found in the western united states, is the dried structure of certain plants that are blown by the wind, kochia, a type of plant that turns into tumbleweed at the end of the summer is a problem for farmers because it takes nutrients away from soil that would otherwise go to more beneficial plants. scientists are concerned that ko:hia plants are becoming resistant to the most commonly used herbicide, glyphosate. in 2014, 19.7 percent of 61 randomly selected kochia plants were resistant to glyphosate. in 2017, 38.5 percent of 52 randomly selecteikochia plants were resistant to glyphosate. do the data provide convincing statistical evidence, at the leve of 0.05, that there has been an increase in the proportion of all kochia plants that are resistant to glyphosale?

Answers

Since we are dealing with a proportion, it is determined by using the z-distribution that there is insufficient evidence to draw the conclusion that the proportion of all kochia plants that are resistant to glyphosate has increased because the test statistic is less than the critical value for the right-tailed test.

In this problem, we consider that:

[tex]p_{1}[/tex] is the proportion in 2014.[tex]p_{2}[/tex] is the proportion is 2017.

What are the hypothesis tested?At the null hypothesis, we test if there has been no increase, that is, the subtraction is of 0.

[tex]$H_{0}: p_{2}-p_{1}=0$[/tex]

At the alternative hypothesis, we test if there has been an increase, hence:

[tex]$H_{1}: p_{2}-p_{1} \neq 0$[/tex]

What is the distribution of the difference of sample proportions?

The proportions and standard errors are given by:

[tex]p_{1}=0.197, s_{1}=\sqrt{\frac{0.197(0.803)}{61}}=0.0509\\p_{2}=0.385, s_{2}=\sqrt{\frac{0.385(0.615)}{52}}=0.0675[/tex]

Hence, the distribution has mean and standard error given by:

[tex]\bar{p}=p_{2}-p_{1}=0.0675-0.0509=0.0166\\s=\sqrt{s_{1}^{2}+s_{2}^{2}}=\sqrt{0.0509^{2}+0.0675^{2}}=0.0845[/tex]

What is the test statistic?

It is given by:

[tex]$z=\frac{\bar{p}-p}{s}$[/tex]

In which p = 0 is the value tested at the null hypothesis, hence:

[tex]z=\frac{0.0166}{0.0845}\\$z=0.2$[/tex]

What is the decision?Considering a right-tailed test, as we are testing if the proportion is greater than a value, with a significance level of 0.05, the critical value is of [tex]$z^{*}=1.645$[/tex]There is insufficient information to establish that the fraction of all kochia plants that are resistant to glyphosate has increased because the test statistic is smaller than the crucial value for the right-tailed test.
