Answer:

He gets 42 visitors 4 weeks after starting to build his website.

He gets 10 new visitors per week.

Step-by-step explanation:

Equation for the number of visitors:

The equation for the number of visitors Timmy's new website receives after t weeks is:

[tex]v(t) = 10t + b[/tex]

In which b is the number of visitors rightly after he starts.

Timmy is building a new website. Right after he starts, he has 2 visitors.

This means that [tex]b = 2[/tex], so:

[tex]v(t) = 10t + 2[/tex]

How many visitors does he get 4 weeks after starting to build his website?

This is v(4). So

[tex]v(4) = 10(4) + 2 = 40 + 2 = 42[/tex]

He gets 42 visitors 4 weeks after starting to build his website.

How any new visitors does he get per week?

After 0 weeks:

[tex]v(0) = 10(0) + 2 = 0 + 2 = 2[/tex]

After 1 week:

[tex]v(1) = 10(1) + 2 = 10 + 2 = 12[/tex]

2 weeks:

After 2 week:

[tex]v(2) = 10(2) + 2 = 20 + 2 = 22[/tex]

22 - 12 = 12 - 2 = 10

He gets 10 new visitors per week.

Answer:

9.12%

Step-by-step explanation:

Yield to maturity is also known as the internal rate of return of a bond

Internal rate of return is the discount rate that equates the after-tax cash flows from an investment to the amount invested

YTM can be calculated with a financial calculator

Cash flow in year 0 = -950  

Cash flow each year from year 1 to 5 = 80

Cash flow in year 6 = 100 + 80 = 1080

YTM = 9.12%

To determine YTM using a financial calculator:

1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.

2. After inputting all the cash flows, press the IRR button and then press the compute button.  

Answer:

( -1 , 5 )

Step-by-step explanation:

Solution = Coordinate where the two lines intersect

The two lines intersect at ( -1 , 5 )

Thus solution = ( -1 , 5 )

Answer:

Step-by-step explanation:

Then,

(i) Breadth of upper rectangle = 2 units

Length of upper rectangle = 8 - 1 = 7 units

Therefore,

Area of the upper rectangle = 7 × 2 = 14 units2

(ii) Breadth of lower rectangle = 1 unit

Length of lower rectangle = 5 units

Therefore,

Area of the lower rectangle = 5 × 1 = 5 units2

Since,

Area of the figure is = Area of upper rectangle + Area of lower rectangle

= 14 units2 + 5 units2

= 19 units2 (Ans) (4th option)

Answer:

The bottom is  11

The median is  12

Step-by-step explanation:

The median is the average of the top and bottom

(13+ 2x-3) /2 = 4x-16

Combine like terms

(10+2x)/2 = 4x-16

Divide by 2

5+x = 4x-16

Subtract x from each side

5+x-x = 4x-16-x

5 = 3x-16

Add 16 to each side

5+16 = 3x-16+16

21 = 3x

Divide by 3

21/3 = 3x/3

7 =x

The bottom is 2x-3 = 2*7-3 = 14-3 = 11

The median is 4x-16 = 4*7-16 = 28 -16 = 12

Answer:

YZ =  12, ML = 11

Step-by-step explanation:

The median is half the sum of the parallel bases, that is

YZ = [tex]\frac{KN+LM}{2}[/tex]

4x - 16 = [tex]\frac{13+2x-3}{2}[/tex] ( multiply both sides by 2 to clear the fraction )

8x - 32 = 10 + 2x ( subtract 2x from both sides )

6x - 32 = 10 ( add 32 to both sides )

6x = 42 ( divide both sides by 6 )

x = 7

Then

YZ = 4x - 16 = 4(7) - 16 = 28 - 16 = 12

ML = 2x - 3 = 2(7) - 3 = 14 - 3 = 11

Answer:

all incorrect

Step-by-step explanation:

I did it in my head so I'm sorry if wrong

Answer:

The last one is incorrect

Step-by-step explanation:

-4c^2 - 2c^2 = -6c^2

9c - c = 8c

9c - c is equal to 8c so that means the polynomial is wrong since they put 10c instead of 8c.

Answer:

The area of the rectangle is 0.0875  sq ft.

Step-by-step explanation:

Given that,

The length of the rectangle, L = 0.35 feet

The breadth of the rectangle, B = 1/4 feet

We need to find the area of the rectangle. The formula for the area of a rectangle is given by :

A = LB

Put all the values,

[tex]A=\dfrac{1}{4}\times 0.35\\\\A=0.0875\ ft^2[/tex]

So, the area of the rectangle is 0.0875  sq feet.

Answer:

Step-by-step explanation:

The probability that a birth in the United States is male during 2018 is 0.511. So there are slightly more males than females born.

In 300  simulated trials, 171 of the births are female and 129 are male. More females are born so it is not consistent with the model.

The expected number of male birth for 300 trials should be 300*0.511 = 153.

The expected number of female = 300-153 = 147

Answer:

C. Both are forthright and confident.

Explanation:

Emily Dickinson's poems "Some Keep the Sabbath Going to Church" and "Because I Could Not Stop for Death" are poems that reflect the poet's real feelings towards things or issues that are accepted to be normal behavior or accepted norms.

But in expressing her own take on both issues, be it attending church as a show of one's religiousness, or death, Dickinson asserts her own beliefs and opinions against the 'normal'. And in both poems, she is forthright and confident in what she believes and shows.

Thus, the correct answer is option C.

Answer:

[tex]x = 2[/tex]

Step-by-step explanation:

Let's solve:

[tex]4x+22=6(x+3)[/tex]

Step 1: Simplify both sides of the equation.

[tex]4x+22=6(x+3) \\ 4x+22=(6)(x)+(6)(3)\\ (Distribute) \\ 4x+22=6x+18[/tex]

Step 2: Subtract 6x from both sides.

[tex]4x+22−6x=6x+18−6x\\ −2x+22=18[/tex]

Step 3: Subtract 22 from both sides.

[tex]−2x+22−22=18−22 \\ −2x=−4[/tex]

Step 4: Divide both sides by -2.

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

Answer:

  735.6 in³

Step-by-step explanation:

The formula for the volume of a sphere is ...

  V = 4/3πr³ . . . . where r is the radius

The radius is half the diameter, so we can write this in terms of diameter as ...

  V = (4/3)π(d/2)³ = (π/6)d³

Using the given diameter, the volume is ...

  V = (π/6)(11.2 in)³ ≈ 735.6186 in³

The volume is about 735.6 cubic inches.
