To find her speed, divide the total distance by the total time:

12.5 miles / 5 hours = 2.5 miles per hour.

[2/SEC(¶/3)•[lim x→0 x^3+8x+10]^2]/[lim θ→0 sinθ/θ]

Oliga [24]

Assuming the pilcrow is supposed to represent pi:

$\frac{\frac{2}{sec(\frac{\pi}{3})}*(\lim_{x \to 0} x^3+8x+10)^2}{ \lim_{\theta \to 0} \frac{sine(\theta)}{\theta}}\\\frac{\frac{2}{\frac{1}{cosine(\frac{\pi}{3})}}*((0)^3+8(0)+10)^2}{\frac{sine((0))}{(0)}}\\\frac{\frac{2}{\frac{1}{\frac{1}{2}}}*(0+0+10)^2}{\frac{0}{0}}\\\frac{\frac{2}{2}*(10)^2}{ \lim_{\theta \to 0} \frac{cosine(\theta)}{1}}\\\frac{100}{cosine((0))}\\\frac{100}{1}\\100$

Point C does not lie on line xy. Can point C lie in the same plane as live xy? Explain

uysha [10]

The answer is yes.

A line and a point outside the line define a unique plane. In other words, there is a single plane that contains a line and a point outside the line. If you are given line XY and point C outside the line, there is a single plane containing both line XY and point C. Therefore, line XY and point C must lie in the same plane.

the first and last term arithmetic sequence are 9 and 165 respectively.if the sum of all the terms of the arithmetic sequence is

diamong [38]

Answer:

40 terms

Step-by-step explanation:

<u>Sum of n terms formula:</u>

Sn = 1/2n(a1 + an)

<u>Solving for n</u>

3480 = 1/2n(9 + 165)
3480 = 87n
n = 3480/87
n = 40

Given 3 sides of a triangle - how to tell it right, acute, or obtuse 8,11, 16

user100 [1]

Using Pythagorean theorem, we can justify our answer.
if c^2 = a^2 + b^2 then triangle is right one,
if c^2 > a^2 + b^2 then triangle is obtuse and
if c^2 < a^2 + b^2 then triangle is acute triangle.

Here a=8, b=11 and c=16
Put these values in the equation
16^2 = 8 ^2 + 11^2
256 = 64 +121
256> 185
So here c^2 > a^2 + b^2 Which means triangle is obtuse triangle.

Answer: Obtuse Triangle

Ainat [17]

According to the given passage the most appropriate option is: C.

A single text produced by a previously unknown society.

<h3>The definition of a single text:</h3>

A single document that ties together the frequently disparate interests of parties involved in a conflict is used in a single-text negotiating strategy, a type of mediation.

<h3>What exactly is a paragraph?</h3>

1. A paragraph with only one brief sentence that clearly states the main idea.

2. A paragraph that consists of a single lengthy sentence that could support three, four, or five sentences.
