Answer:

  D.  (x² -2x -3) +(-x² +4x +2)

Step-by-step explanation:

The tiles on the first row model (x² -2x -3).

The tiles on the second row model (-x² +4x +2).

If the difference is being modeled, it will show as ...

  (x² -2x -3) -(-x² +4x +2) = (x -2x -3) +(x² -4x -2) . . . . . matches none

If the sum is being modeled, it will show as ...

  (x² -2x -3) +(-x² +4x +2) . . . . . matches D

As is often the case, you can select the correct answer without even any understanding of the question. You can do that because the correct answer is the only one that is a true statement. All of the other answer choices are incorrectly "simplified."

Answer:

x^1 = 1, x^2 =2

Step-by-step explanation:

its hard to explain but there's the answer

Answer:

30 degree

Step-by-step explanation:

x + x + 60 + 60 = 180 degree (being sum of interior angles of a triangle )

2x  120 = 180

2x = 180 - 120

x = 60/2

x = 30 degree

Answer:

I'm not quite sure but there is 180 degrees in a triangle and they give us two 60 degrees which add up to 120. So, I'm assuming x = 60 or either 30 degrees if we're solving for both the x's at the top.

I'm really sorry if this is wrong.

Answer:

D

Step-by-step explanation:

The radius of a circle refers to a segment connecting the center of the circle to the circumference of the circle. This can be seen in selection D), as a segment connects the center of the circle (O) to the circumference or outer edge of the circle.

Answer:

The trade discount is

$235.4

Step-by-step explanation:

Given data

Slacks= $22

Jumpers= $37

Number of orders for Slacks= 30

Number of orders for Jumpers= 40

Total cost

22*30=$660

37*40=$1480

=$2140

11% discount can be computed as

=11/100*2140

=$235.4

Answer:

x = 3

Step-by-step explanation:

Assuming the acute angle are 45degrees

Hypotenuse = 3√2

Opposite = x

According to SOH CAH TOA

Sin 45 = opposite//hypotenuse

Sin 45 = x/3√2

1/√2 = x/3√2

Cross multiply

√2x = 3√2

x = 3

Hence the value of x is 3

Answer:

21 times 660 and then you will get the answer

Step-by-step explanation:

Answer:

The seelijg price is $48.

Step-by-step explanation:

Markup is the amount a store adds to its cost of an item to come up with the selling price.

store cost + markup = selling price

If the markup on an item is 50%, then the store adds 50% of its cost to its cost to arrive at the selling price.

$32 + 50% of $32 =

= $32 + 0.5 * $32

= $32 + $16

= $48

Answer:

50% of 32 is 16 so it it 16$

Answer: 15268.1403 unit^3 (unit: cm,m,mm)

Step-by-step explanation:

volume of a cone= 1/2*pi*r^2*h

r= radius (unit: cm,m,mm)

h= perpendicular height (unit: cm,m,mm)

volume= 1/2*pi* (9)^2* 120 = 15268.1403 unit^3

Answer:

Options (1) and (5)

Step-by-step explanation:

Expression that defines the function is,

[tex]f(x)=\frac{1}{2}x+\frac{3}{2}[/tex]

Option 1

[tex]f(-\frac{1}{2})=\frac{1}{2}(-\frac{1}{2})+\frac{3}{2}[/tex]

          [tex]=-\frac{1}{4}+\frac{3}{2}[/tex]

          [tex]=-\frac{1}{4}+1+\frac{1}{2}[/tex]

          [tex]=1+\frac{1}{4}[/tex]

          [tex]=1\frac{1}{4}[/tex]

So, [tex]f(-\frac{1}{2} )=-2[/tex] is false.

Option 2

f(0) = [tex]\frac{1}{2}(0)+\frac{3}{2}[/tex]

     = [tex]\frac{3}{2}[/tex]

True.

Option 3

f(1) = [tex]\frac{1}{2}(1)+\frac{3}{2}[/tex]

    = [tex]\frac{3+1}{2}[/tex]

    = 2

Therefore, f(1) = -1 is false.

Option 4

[tex]f(2)=\frac{1}{2}(2)+\frac{3}{2}[/tex]

       [tex]=1+1+\frac{1}{2}[/tex]

       [tex]=2\frac{1}{2}[/tex]

Therefore, f(2) = 1 is false.

Option 5

f(4) [tex]=\frac{1}{2}(4)+\frac{3}{2}[/tex]

     [tex]=2+\frac{3}{2}[/tex]

     [tex]=\frac{4+3}{2}[/tex]

     [tex]=\frac{7}{2}[/tex]

True.

Options (1) and (5) are the correct options.

Answer:

A is the answer........

Answer:

[tex]y - 0= \frac{ - 1}{5}( x + 15)[/tex]

Answer:

The function is as follows:

def count_bases(DNA_str):

   retDNA = {}

   for i in DNA_str:

       if i in retDNA:

           retDNA[i]+=1

       else:

           retDNA[i] = 1

   return retDNA

Step-by-step explanation:

This defines the function

def count_bases(DNA_str):

This initializes a dictionary

   retDNA = {}

This iterates through the dictionary

   for i in DNA_str:

If an item exists in the dictionary

       if i in retDNA:

The count is updated by 1

           retDNA[i]+=1

Otherwise

       else:

The count is set to 1

           retDNA[i] = 1

This returns the DAN

   return retDNA

Answer:

Step-by-step explanation:

11.04 = 10(1.02)^n

1.104 = 1.02^n

ln 1.104 = ln 1.02^n

ln 1.104 = n ln 1.02

n = ln 1.104/ ln 1.02

n = 4.99630409516

4.99 can be rounded to 5.

So a reasonable domain would be 0 ≤ x < 5

PART B)

f(0) = 10(1.02)^0

f(0) = 10(1)

f(0) = 10

The y-intercept represents the height of the plant when they began the experiment.

f(1) = 10(1.02)^1

f(1) = 10(1.02)

f(1) = 10.2

(1, 10.2)

f(5) = 10(1.02)^5

f(5) = 10(1.1040808)

f(5) = 11.040808

f(1)=10(1.02)^1

f(1)=10.2

Average rate= (fn2-fn1)/(n2-n1)

                     =11.04-10.2/(5-1)

                    =0.22

the average rate of change of the function f(n) from n = 1 to n = 5 is 0.22.  

Answer:

Part A

The domain should be 0 ≤n≤5

Part B

f(n) = 10(1.02)^n

The function is in the form y =a b^x  where a is the y intercept

The y intercept is 10.  This is the value when n =0 days.

Part C

The average rate of growth over the 4 days is .21 cm per day

Step-by-step explanation:

f(n) = 10(1.02)^n

Part A

Let f(n) = 11.04

11.04 = 10 * 1.02 ^n

Divide each side by 10

11.04/10 = 1.02^n

1.104 = 1.02^n

Taking the log of each side

log 1.104 = log 1.02^n

We know log a^b = b log a

log 1.104 = n log 1.02

log 1.104 / log 1.02 = n

4.99630=n

Rounding n to 5

The domain should be 0 ≤n≤5

Part B

f(n) = 10(1.02)^n

The function is in the form y =a b^x  where a is the y intercept

The y intercept is 10.  This is the value when n =0 days.

Part C

To find the average rate of change

f(5) - f(1)

-----------

5-1

f(5) = 11.04  

f(1) = 10 *1.02 =10.2

11.04 - 10.2

-----------

5-1

.84

-----

4

.21 cm per day

The average rate of growth over the 4 days is .21 cm per day
