Look at the picture.

\cos 75^\circ =\frac{x}{25} \\
25 \cos 75^\circ = x \\
25 \times 0.2588 \approx x \\
x \approx 6.47

The base of the ladder is 6.47 feet from the house.

Does (-2)^n/( 3^n+1) converge or diverge?
hodyreva [135]
\left|\dfrac{(-2)^n}{3^n+1}\right|=\dfrac{2^n}{3^n+1}

As n\to\infty, the sequence a_n=\left(\dfrac23\right)^n converges to zero.

If you're talking about the infinite series

\displaystyle\sum_{n\ge0}\dfrac{(-2)^n}{3^n+1}

well we've shown by comparison that this series must also converge because we know any geometric series \sum\limits_n r^n will converge as long as |r|.

Answer: 14

Step-by-step explanation:

Okay so it asks in all, which means morning distance + afternoon distance

We got the afternoon distance so now we have to find the morning one

it says the afternoon distance (6), is 25% less than the morning distance.

Which means the afternoon distance is 0.75 of the morning distance.

so 0.75x = 6, x = 6/0.75 = 8

Then you add 8 to 6 to get 14

a hiking path is represented by the equation y=3/8x on a coordinate map. The county would like to create a parallel path for bik
stepladder [879]

Answer:

The equation of the bike path on a coordinate map is represented by y = \frac{3}{8}\cdot x +1.

Step-by-step explanation:

From Analytical Geometry, we know that resultant parallel line is a translated version of parent line. Two lines are parallel to each other when they share the same slope. The resultant line can be construted from slope-point form:

y-y_{o} = m_{\parallel}\cdot (x-x_{o})

Where:

x_{o}, y_{o} - Components of known point, dimensionless.

m_{\parallel} - Slope of the parallel line, dimensionless.

In addition, a line has also this form:

y = m\cdot x + b

Where:

x - Independent variable, dimensionless.

y - Dependent variable, dimensionless.

m - Slope, dimensionless.

b - y-Intercept, dimensionless.

Given that parent function is y = \frac{3}{8}\cdot x, the slope of the resulting line is m_{\parallel} = \frac{3}{8}. Now, if x_{o} = 16 and y_{o} = 7, we obtain the equation of the line:

y-7 = \frac{3}{8}\cdot (x-16)

y = \frac{3}{8}\cdot x +1

The equation of the bike path on a coordinate map is represented by y = \frac{3}{8}\cdot x +1.
