Question 3 of 13 Which represents the explicit formula for the arithmetic sequence a n = 15 + 5 ( n − 1 ) a n = 15 + 5 n - 1 in

tatyana61 [14]

Answer:

$\textbf{Option C: \mathmode{\mathit{f(n) = 5n + 10}}}\\$

Step-by-step explanation:

$\textrm{There are two simple ways to solve the equation:}\\{\underline{\textbf{Method I:}}\hspace{3mm} \textup{\textrm{ Substitute \mathmode{n = 1} in the equation{\mathit{a} = 15 + 5(n - 1)}}}}\\\textup{\textrm{i.e., \mathrm{a = 15 + 5(0) = 15}}}\\\\$

$\textup{\textrm{In the options, again substitute \mathbf{n = 1}.}}\\\textup{\textrm{We can easily see that only Option \mathbf{C} satisfies the equation and renders 15. }}\\\textup{\textrm{Now for \textbf{\underline{Method II:}}\textup{\textrm{Simplify the given equation into \mathit{a = 15 + 5n - 5}}}}}\\\implies \textup{\textrm{a = 5n + 10}}\\$

What is the equation of a line in slope intercept form that is perpendicular to y=2/3x+2 and passes through the points (-2,2)? H

JulijaS [17]

Answer:

$y = -\frac{3}{2}x -1$

Step-by-step explanation:

Given

Perpendicular to $y = \frac{2}{3}x + 2$

Pass through $(-2,2)$

Required

Determine the line equation

First, we need to determine the slope of $y = \frac{2}{3}x + 2$

An equation is of the form:

$y = mx + b$

Where

$m = slope$

In this case:

$m = \frac{2}{3}$

Next, we determine the slope of the second line.

Since both lines are perpendicular, the second line has a slope of:

$m_1 = \frac{-1}{m}$

$m_1 = \frac{-1}{2/3}$

$m_1 = -\frac{3}{2}$

Since this line passes through (-2,2); The equation is calculated as thus:

$y - y_1 = m_1(x - x_1)$

Where

$(x_1,y_1) = (-2,2)$

This gives:

$y - 2 = -\frac{3}{2}(x - (-2))$

$y - 2 = -\frac{3}{2}(x +2)$

$y - 2 = -\frac{3}{2}x -3$

Add 2 to both sides

$y - 2+2 = -\frac{3}{2}x -3 + 2$

$y = -\frac{3}{2}x -1$
