T_n = a_1 + d(n - 1)&#10;

T_n = 52 + 12(n - 1)

T_n = 52 + 12n - 12

T_n = 40 + 12n

When n = 102,
T_{102} = 40 + 12(102) = 1264

Answer: 1264

Noah is thinking of two fractions that have a sum of 35. Each fraction has a numerator of 1.
Zinaida [17]

The denominators of the fractions are 2 and 10.

<h3>The fractions with numerators of 1 that have sum of 3 / 5  is calculated below</h3>

The sum of the fractions are 3 / 5. Each of the fractions have a numerator of 1. Therefore, let the denominators be x and y

  • 1 / x + 1 / y = 3 / 5

Therefore,

1 / x  + 1 / y = 3 / 5

y + x / xy = 3 / 5

cross multiply

5y + 5x = 3xy

Using hit and trial method,

5(2) + 5(10) = 3(10)(2)

10 + 50 = 60

60 = 60

The values are same.

Therefore, the denominators are 2 and 10.

A line passes through the point (-1, - 8) and has a slope of -6. Write an equation for this line.In slope intercept form
Alenkasestr [34]

      \rule{50}{1}\large\blue\textsf{\textbf{\underline{Question:-}}}\rule{50}{1}

    <em>A line passes through the point (-1, -8) and has a slope of -6. Write an </em>

<em>      equation for the line in slope-intercept form.</em>

<em />

<em />\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}

First, let's write the equation of the line in Point-slope form:-

       \Large\text{$y-y_1=m(x-x_1)$}

Replace y₁ with -8, m with -6, and x₁ with -1:-

          \Large\text{y-(-8)=-6(x-(-1)}

\bigstar On simplification,

         \Large\text{y+8=-6(x+1)}

\bigstar Now let's convert it into slope-intercept form:-

                     \Large\text{y+8=-6x-6}

\bigstar<em> </em>On further simplification,

\Large\text{y=-6x-6-8}

\bigstar Finally, We get

\Large\textit{y=-6x-14}

\Uparrow\textsf{Our equation in slope-intercept form}

A bouncing ball reaches a height of 27 feet at its first peak, 18 feet at its second peak, and 12 feet at its third peak. Descri
dexar [7]
The sequence:
a 1 = 27 ft,  a 2 = 18 ft,  a 3 = 12 ft.
a 2 = a 1 * q
q = a 2 / a 1 = 18 / 27 = 2 / 3
a 4 = a 3 * q = 12 * 2 / 3 = 8 ft

Reduce the rate 100miles per 4 hours to its unit rate and write the miles portion of your answer in the space provided
Reika [66]
The unit rate would be number of miles per hour ( 1 hour).

 Divide the total number of miles by the total number of hours:

100 miles / 4 hours = 25 miles per hour.

The unit rate is 25 miles.
