Answer:

2.)4n>(n/2)^2

3. (The problem isn't clear)

4.)n^2+2n-3=129

5.)n-5=171

Step-by-step explanation:

2.)

4n(four times the number) >(larger than) (n/2)^2 (half the number squared)

4.)

Sum=addition

n^2 (number squared) +2n (twice the number)-3=129

5.)

N(unknown number of pages) -5(amount of pages already read)= 171(the number of pages it took her to finish)

2. Rainey graphed a function with exponential growth and an initial value of 15. Which of the following could represent the equa
Mars2501 [29]

Exponential equation are functions defined by y =ab^x

The equation that could represent Rainey graph must take the form y =15b^x

<h3>How to determine the equation</h3>

An exponential equation is represented as:

y =ab^x

Where:

  • a represents the initial value
  • b represents the rate

The initial value (a) is 15.

So, the equation becomes

y =15b^x

The graph is not given;

So, the equation cannot be determined.

Assume that the rate is 2.

Then the function would be: y =15(2)^x

Find the area of the kite.<br> 13<br> 12<br> 8<br> 主<br> A=<br> lin²
rewona [7]

Answer:

100㏑²

Step-by-step explanation;

first of all you find the base using the pythagoras theorem

that is, √13² - 12² =√25 = 5

so 5 is the base of the right angle in the big isoceles triangle

so the base of the isoceles triangle is 10 [5 + 5]

so for the first triangle the area is 60㏑²

the second triangle is 40㏑²

therefore 60 + 40 = 100㏑²

The length of a rectangle is 4 centimeters more than twice its width of the perimeter of the rectangle is 86centimeters find the
lana66690 [7]

Answer:

Width= 13 cm

length=30cm

Step-by-step explanation:

Let the length of the rectangle be 'L'

And the width of the rectangle be 'W'

Perimeter= 86 cm

According to the statement:

        Length= 2*Width+4\\L=2W+4

Perimeter of a rectangle= 2(Length+Width)

86=2(2W+4+W)\\86/2=3W+4\\43=3W+4\\3W=43-4\\3W=39\\W=39/3\\W=13 cm\\\\Length(L)=2W+4\\=2(13)+4=26+4=30 cm\\Length=30 cm

                               Width= 13 cm

                                length=30cm
