​

Answers

Answer 1
Answer:

Answer:

The graph is attached below.

Step-by-step explanation:

Given the function

f\left(x\right)\:=\:\left(1/3\right)^x+1

Exponentiation function have a horizontal Asymptotes.

Finding the horizontal Asymptotes

\mathrm{Exponential\:function\:of\:the\:form}\:f\left(x\right)\:=c\cdot \:n^(ax+b)+k\:

\mathrm{has\:a\:horizontal\:asymptote}\:y=k\:

k=1

\mathrm{The\:horizontal\:asymptote\:is:}

y=1

Finding y-intercepts

y\mathrm{-intercept\:is\:the\:point\:on\:the\:graph\:where\:}x=0

y=\left((1)/(3)\right)^0+1

\mathrm{Apply\:rule}\:a^0=1,\:a\ne \:0

\left((1)/(3)\right)^0=1

y=1+1

\mathrm{Add\:the\:numbers:}\:1+1=2

y=2

\mathrm{Y\:Intercepts}:\:\left(0,\:2\right)

The graph is attached below.

How many integers are there between √15 and √68? A. Four
B. Five
C. Six
D. Seven

Answers

There are five integers between √15 and √68

This sign - √ - represents square root.

Th square root is a number when multiplied by itself produces another number.

For example. 7 is the square root of 49 because 7 x 7 = 49

The square root of 15 is 3.87  

The square root of 68 is 8.25

The integers between these values are 4, 5, 6, 7, 8. There are five integers

√(15) =3.9\n√(64) =8\n4,5,6,7

Match the pairs of polynomials to their products. (xy + 9y + 2) and (xy – 3) x2y2 + 3x2y – 7xy – 27x – 18 (2xy + x + y) and (3xy2 – y) 6x2y3 – 2xy2 + 3x2y2 – xy + 3xy3 – y2 (x – y) and (x + 3y) x3y + 3x2 + 3x2y2 + 7xy – 6 (xy + 3x + 2) and (xy – 9) x2 – 9y2 (x2 + 3xy – 2) and (xy + 3) (x + 3y) and (x – 3y)

Answers

Answer:

Step-by-step explanation:

1) (xy+ 9y + 2) and (xy – 3)

Each term of second expression will be multiplied by first bracket.

xy(xy+9y+2) -3(xy+9y+2)

x²y²+9xy²+2xy-3xy-27y-6

x²y²+9xy²-xy-27y-6

2)(2xy + x + y) and (3xy2 – y)

3xy²(2xy+x+y) -y(2xy+x+y)

6x²y³+3x²y²+3xy³-2xy²-xy-y²

6x²y³ – 2xy² + 3x²y² – xy + 3xy³ – y²

3)  (x – y) and (x + 3y)

x(x-y) +3y(x-y)

x²-xy+3xy-3y²

x²+2xy-3y²

4) (xy + 3x + 2) and (xy – 9)

xy(xy + 3x + 2) -9(xy + 3x + 2)

x²y²+3x²y+2xy-9xy-27x-18

x²y²+3x²y-7xy-27x-18

5) (x2 + 3xy – 2) and (xy + 3)

xy(x2 + 3xy – 2) +3(x2 + 3xy – 2)

x³y+3x²y²-2xy+3x²+9xy-6

x³y+3x²+3x²y²+7xy-6

6) (x + 3y) and (x – 3y)

x(x + 3y) -3y(x + 3y)

x²+3xy-3xy-9y²

x²-9y² ....

Answer: (xy + 9y + 2) and (xy – 3) —> x3y + 3x2 + 3x2y2 + 7xy – 6

(2xy + x + y) and (3xy2 – y) —> 6x2y3 – 2xy2 + 3x2y2 – xy + 3xy3 – y2

(x – y) and (x + 3y) —> (x + 3y) and (x – 3y)

 (xy + 3x + 2) and (xy – 9) —> x2y2 + 3x2y – 7xy – 27x – 18

What is 5d=470 and what is 8a=47

Answers

5d=470:

in this case we have to divide both sides by 5:

d=94

8a=47:

in this case we have to divide both sides by 8:

a=5.875

as a general rule, if you want to find out a value of a in
ab=c

you have to divide both sides of the equation by b (if it's not zero); then you will have left:

a=c/b

and if you calculate c/b, this will give you the answer
5d= 470 \n \n d=470:5 \n \n \boxed{\boxed{d= 94}} \n \n 8a=47 \n \n a=47:8 \n \n \boxed{\boxed{a=5.875}}

Which of the following describes a one-to-one function?

Answers

Option C) is correct.

Step-by-step explanation:

One to one function can be checked by using horizontal line test and vertical line test.

A) y = \left | x \right |

the graph of this function ia attached below named as Graph 1.

The above function did not pass the horizontal line test therefore it is not a one to one function.

\rm B) \;y = \left\{\begin{matrix}4 & , & x<0\n 5 & , & 0\leq x\leq 2\n 6 & , & x > 2\end{matrix}\right.

the graph of this function is attached below named as Graph 2.

The above function did not pass the vertical line test therefore it is not a one to one function.

\rm C)\;y = \left\{\begin{matrix}5x-1 & , & x<-2\n x-9 & , & x \geq -2\n \end{matrix}\right.

the graph of this function is attached below named as Graph 3.

The above function pass the horizontal line test as well as vertical line test and therefore this function is one to one function.

\rm D)\; y=[[x]]

the graph of this function ia attached below named as Graph 4.

The above function is a floor function and fail the vertical line test.

Therefore, correct answer is option C).

check the picture below.


bearing in mind that a one-to-one function must pass the horizontal line test as well as the vertical line test.


now, |x| is the graph of a letter V more or less, and that'd fail the horizontal line test.


the first piecewise function, has say 4 : x < 0, namely for all values before 0, "y" is a steady constant of 4, that will be a horizontal line and will definitely fail the vertical line test.


[[x]] is pretty much the "floor function", and you can do a quick google search on it, or do it in your calculator, it should have a floor function, but that one will definitely fail the vertical line test as well.
