If the arc is 60, the inscribed angle is 1/2 (60) = 30

If the arc is 70, the inscribed angle is 1/2 (70) = 35

the triangle is 30+35 +x=180

65+x =180

subtract 65 from each side

x=115

Find f(x) and g(x) so that the function can be described as y=f(g(x))<br> y=(9/x^2)+2

eduard

there are many combinations for it, but we can settle for say

$\bf \begin{cases} f(x)=x+2\\[1em] g(x)=\cfrac{9}{x^2}\\[-0.5em] \hrulefill\\ (f\circ g)(x)\implies f(~~g(x)~~) \end{cases}\qquad \qquad f(~~g(x)~~)=[g(x)]+2 \\\\\\ f(~~g(x)~~)=\left[ \cfrac{9}{x^2} \right]+2\implies f(~~g(x)~~)=\cfrac{9}{x^2}+2$

The formula sa

sergeinik [125]

Answer:

The correct option is (b).

Step-by-step explanation:

The formula for the side of a cube of surface area SA is as follows :

$s=\sqrt{\dfrac{SA}{6}}$

When SA = 180 m²

$s=\sqrt{\dfrac{180}{6}}\\\\s=\sqrt{30}$

When SA = 120 m²

$s=\sqrt{\dfrac{120}{6}}\\\\s=\sqrt{20}\\\\=2\sqrt5$

Difference,

$=30-2\sqrt5$

So, the correct option is (b).

Write four numbers that round to 700000 when rounded to the nearest hundred thousand

ruslelena [56]

you need to look at the number in the spot to the right of the hundred thousands place to determine what to do. If it is 4 or below, they all drop to 0. If it is 5 or above, they all drop to 0 and the hundred thousands place goes up by 1.

651000, 663200, 723000, 749999

Solve 2(3a² - 1) - 6a = 5a {-1/2, 2/3} {-1/6, 2} {}

kirill [66]

6a^2 - 2 -6 a -5a = 0

6a^2 -11 a - 2 = 0

a = 2 , a= -1/6
