Answer:

4

Step-by-step explanation:

In the graph of the function, between the interval (-4, 4), there are 4 values of x for which the given function is not differentiable.

The method of determining the derivative of an implicit function by differentiating each term separately, expressing the derivative of the dependent variable as a symbol, and solving the resulting expression for the symbol.

here,
The function from observation seems to be a discontinuous function,
And the function is not differentiable at x = -1, 0, 1, and 3.
So there are 4 points in the interval (-4, 4) where the function is not differentiable.

Thus, In the graph of the function, between the interval (-4, 4), there are 4 values of x for which the given function is not differentiable.

ANS:2113

Answer:

Domain:  (-∞, 2] U (3, 6]
Range: (-∞ , 1] U (-1, 4]

Step-by-step explanation:

This is a piecewise function. It has a discontinuity at x=2 and x = 3

The domain of a piecewise function is the union of the domains of each piece of the function. Similarly the range for a piecewise function is the union of the ranges for each piece of the function

Looking at the graph, we can see two subdomains. When x ≤ 2 , we have one subdomain and when x > 3 there is another subdomain. We state this as
D = - ∞ < x  ≤ 2 or 3 < x ≤ 6
In interval notation we represent this as

D =  (-∞, 2] U (3, 6]

The nature of the brackets is important a [ or ] bracket means that the value to which it is attached is included whereas an open bracket, (    or     ) means that value is not included

For example,  (-∞, 2] means that everything below x = 2 to -∞ is part of the domain but it does not include -∞; since at -∞, a function is not defined. However it does include 2 in the domain as can be seen by the closed bracket on the right

The other subdomain is for x > 3 (note: a filled circle means the value is included, an empty circle denotes the value is excluded)

The second subdomain is
3 < x ≤ 6
In interval notation, it is (3, 6]

So the total domain is the union of the two intervals

The range is also discontinuous and there are two distinct ranges. The range is nothing but all the set of values generated by the function. So we look at all possible values for y that the function produces

The Range of this function is  -∞ < f(x) ≤ 1 or -1 < f(x) ≤ -4
In interval notation this is
R = (-∞ , 1] U (-1, 4]

Answer:

Margret need to get 4 boxes of cookies.

Step-by-step explanation:

Total friends = 3

Cookies each friend will get = 8

Each box has cookies = 6 cookies

How many boxes does Margret need to get?

Total cookies will be= Total friends x Cookies each friend will get

Total cookies will be= 3 x 8 = 24

If one box has 6 cookies and we need total 24 cookies so, divide 24 by 6 to get number of boxes

Number of boxes = Total cookies/ number of cookies in one box

Number of boxes = 24/6

Number of boxes  = 4

So, Margret need to get 4 boxes of cookies.

By subtraction of functions, the length of the line segment BC is equal to 79 - 2 · x units.

In this question we find to two line segments that are collinear to each other. Each line is represented by a linear functions, whose length equations are:

AB = 4 · x + 17             (1)

AC = 96 + 2 · x            (2)

AB + BC = AC  

BC = AC - AB               (3)

Then, by (1) and (2) on (3):

BC = (96 + 2 · x) - (4 · x + 17)

BC = 79 - 2 · x

By subtraction of functions, the length of the line segment BC is equal to 79 - 2 · x units.

After a quick investigation, we conclude that the statement has typing mistakes, correct form is shown below:

If AB = 4 · x + 17 and AC = 96 + 2 · x, then find the expression of BC.

as both points lie on x-axis

The value of 'r' in terms of 'V' is calculated as 0.99√V.

The square root of a number is a value that, when multiplied by itself, yields the original number. The square root is the opposite of squaring a number.

Now, the given expression in the question is;

V= 1/3(3.14)r²

This can be written in the term of V as;

r² = (V×3)/3.14

Taking square root on the both sides;

r = √[(V×3)/3.14]

r = 0.99√V

Thus, the value of the r is obtained as 0.99√V.

Answer:

P(45<X<81) = P(-3<z<3)=0.9974 or 99.74%

Step-by-step explanation:

Mean = 63

Standard Deviation =6

We need to find probability that X lies between 45 and 81 i.e P(45<X<81)

First we will find z-score for X=45 and X=81

For X=45 the z-score can be found using formula:  [tex]z-score=\frac{X-\mu}{\sigma}[/tex]

Putting values and finding z-score

[tex]z-score=\frac{X-\mu}{\sigma}\\z-score=\frac{45-63}{6}\\z-score=-3[/tex]

For X=45, z-score is -3

For X=81 the z-score can be found using formula:  [tex]z-score=\frac{X-\mu}{\sigma}[/tex]

Putting values and finding z-score

[tex]z-score=\frac{X-\mu}{\sigma}\\z-score=\frac{81-63}{6}\\z-score=3[/tex]

For X=81, z-score is 3

Now finding the probability of P(-3<z<3)

It can be solved as:

P(-3<z<3)=P(z<3)-P(z<-3)

Looking at the z-score table to find

P(z<3)= 0.9987

P(z<-3)=0.0013

So, P(-3<z<3)=P(z<3)-P(z<-3)

P(-3<z<3)=0.9987 - 0.0013

P(-3<z<3)=0.9974

or P(-3<z<3)= 99.74%

So, P(45<X<81) = P(-3<z<3)=0.9974 or 99.74%

Triangle X with vertices (−2, 4), (2, 4), and (−2, 2)

Two similar triangles have the same corresponding ratio thus the triangle similar to{ (−1, 2), (1, 2), and (−1, 1) } is { (−2, 4), (2, 4), and (−2, 2) } thus option (A) will be correct.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

As per the given vertices of a triangle (−1, 2), (1, 2), and (−1, 1).

The plot of the triangle using the above vertices plotted below,

The triangle with vertices (−2, 4), (2, 4), and (−2, 2) also has been plotted.
