In Bolandia, the streets are constructed from 10-metre pieces. A lamppost must be placed at both

nadezda [96]

Answer: 340m

Explanation:

Given that:

Streets are constructed from 10 m pieces;

A lamppost is placed at both ends and at every 10 m along its length ;

A lamppost is also placed at every notice board along its length :

Given that:

Einstein Street has 42 lamppost and 7 notice boards :

So,

7 lamppost for 7 notice boards :

Lamppost left = 42 - 7 = 35 lamppost

2 lamppost placed at both ends :

Lamppost left = 35 - 2 = 33 lamppost

Hence, the remaining is placed at 10 m along its length:

Hence, length of Einstein street :

33 lamppost each placed 10m from the starting lamppost = (33 * 10) = 330m

Distance between 33rd lamppost and the ending lamppost = 10m

Hence, total length = (330 + 10) = 340 m

Aloiza [94]

Considering the situation described above, some of how September 11th affected North Carolina’s economy include "<u>it led to the creation of thousands of military jobs in the state</u>."

The other way September 11th affected North Carolina’s economy is that <u>"it encouraged more defense and military spending."</u>

<h3>September 11, 2001, Terrorist Attack</h3>

September 11, 2001, Terrorist Attack was an attack on the United States targeting significant buildings such as Pentagon, World Trade Centers, and U.S Capitol.

Following the saddened incident that led to the immediate death of about 3,000 people, its effects were felt across the United States, including North Carolina.

Some of the effects led to increment in the militarization of North Carolina, making the state become the fourth-ranked state with military personnel in the United States with 166,000 troops.

Hence, in this case, it is concluded that the correct answer is options B and D.

HEYY I NEED HELP WITH AN AP CALC ASSIGNMENT ASAP

Vladimir79 [104]

CALCULATOR PART

1. The area of R + S is unsigned, meaning you want to find

$\displaystyle\int_a^b\left|f(x)-g(x)\right|\,\mathrm dx$

where $[a,b]$ is the interval between the leftmost and rightmost intersections of $f$ and $g$ .

First use your calculator to find these intersections:

$\cos x=\dfrac{x+1}3\implies x\approx-3.64,x\approx-1.86,x\approx0.889$

so that $a=-3.64$ and $b=0.889$ . Now compute the integral using your calculator:

$\displaystyle\int_a^b\left|f(x)-g(x)|\,\mathrm dx\approx1.662$

2. The volume, using the washer method, is given by the integral

$\displaystyle\pi\int_{-1.86}^{0.889}(|2-g(x)|^2-|2-f(x)|^2)\,\mathrm dx\approx12.078$

3. A circle of radius $r$ has area $\pi r^2$ ; a semicircle with the same radius thus has area $\frac{\pi r^2}2$ . Each cross section of this solid is a semicircle whose diameter is the vertical distance between $f(x)$ and $g(x)$ , or $|f(x)-g(x)|$ . In terms of the diameter $d=2r$ , the area of each semicircle would be $\frac{\pi d^2}8$ . Then the volume of the solid is

$\displaystyle\frac\pi8\int_{-3.64}^{-1.86}|f(x)-g(x)|^2\,\mathrm dx\approx0.0425$

NON-CALCULATOR PART

4. The mean value theorem says that for a function $F$ continuous on an interval $[a,b]$ and differentiable on $(a,b)$ , there is some $c\in(a,b)$ such that

$F'(c)=\dfrac{F(b)-F(a)}{b-a}$

If this $F$ happens to be an antiderivative of $f$ , then we end up with

$f(c)=\displaystyle\frac1{b-a}\int_a^bf(x)\,\mathrm dx$

$\cos x$ is continuous and differentiable everywhere, so the MVT applies. We have $F'(x)=f(x)=\cos x$ , so the MVT tells us there is some $c\in[0,\pi$ such that

$\cos c=\dfrac{\sin\pi-\sin0}{\pi-0}=0$

That is, the average value of $f(x)$ on $[0,\pi]$ is 0. The MVT says there is some $c$ in the interval such that the function takes on the average value itself; this happens for $c=\frac\pi2$ .

5. This question seems to be incomplete...
