<h3><u>Answer</u> :</h3>

It is clear from the diagram that,

ㄥ6 + ㄥ8 = 180

⇒ (2x - 5) + (x + 5) = 180

⇒ (2x + x) + (5 - 5) = 180

⇒ 3x + 0 = 180

⇒ x = 180/3

⇒ x = 60°

◈ From the geometry of figure,

ㄥ3 = ㄥ6

⇒ ㄥ6 = (2x - 5)

⇒ ㄥ6 = (2×60 - 5)

⇒ ㄥ6 = 120 - 5

⇒ <u>ㄥ6 = 115°</u>

Why does pi continue infinitely

Anton [14]

It's an irrational number so that means it's value is virtually indiscernible. That's why it seems to go on forever but its most basic form is 3.14.

Use the following functions for 10–12:

Step2247 [10]

h(x) = f(x) + g(x) = $h(x) = 18.5x-16$
h(x) = g(x) – f(x) = $h(x) = 23.5x-40$
h(x) = 4g(x) = $h(x) = (84x-112)$

<u>Step-by-step explanation:</u>

Here we have , f(x) = -2.5x + 12; g(x) = 21x - 28 or $f(x) = -2.5x + 12, g(x) = 21x - 28$ .

10. Find h(x) = f(x) + g(x).

⇒ $h(x) = f(x) +g(x)$

⇒ $h(x) = ( -2.5x + 12)+( 21x - 28)$

⇒ $h(x) = ( 21x-2.5x )+( 12 - 28)$

⇒ $h(x) = 18.5x-16$

11. Find h(x) = g(x) – f(x).

⇒ $h(x) = g(x)-f(x)$

⇒ $h(x) = ( 21x - 28)-( -2.5x + 12 )$

⇒ $h(x) = ( 21x+2.5x )+( -12 - 28)$

⇒ $h(x) = 23.5x-40$

12. Find h(x) = 4g(x).

⇒ $h(x) = 4g(x)$

⇒ $h(x) = 4( 21x - 28)$

⇒ $h(x) = (84x-112)$

What is the vertex of the graph of y = 2(x - 3)2 + 4?

Dvinal [7]

Answer:

(3, 4)

Step-by-step explanation:

vertex is (h, k)

this equation is written in the form of

y = a(x -h) +k

which is why the vertex is (3, 4)

The university police department keeps track of the number of tickets it write in a year. Last year the campus police wrote 1460

AlladinOne [14]

Answer:

Step-by-step explanation:

We are given that Ticket writing on campus follows a Poisson process.

Last year the campus police wrote 1460 tickets

So, $X \sim Poisson (1460 / year)$

1 year = 365 days

So, E(Y) = $\frac{1460}{365}=4$

So, the standard deviation of the number of tickets written per day by the campus police = $\sqrt{4} =2$

Hence the standard deviation of the number of tickets written per day by the campus police is 2
