Answer:

C. x = -1 ; x ~8.1

Step-by-step explanation:

First we graph $f(x)= -\sqrt{x+2} -3$

Here we have x+2 under the square root. x+2>=0, x>=-2

So we take some x values greater than -2 and find out f(x) to make a table for graphing

x f(x)

-2 $-\sqrt{-2+2} -3=-3$

-1 -4

2 -5

Graph it and extent the graph

Now we graph $g(x)= -2|x-3| + 4$

Given equation is in the form of g(x) = a|x-h| + k

where (h,k) is the vertex

here h= 3 and k = 4, so vertex is (3,4)

Now make a table, pick some numbers for x less than and greater than vertex

x y

-1 $-2|-1-3| + 4=-4$

0 $-2|0-3| + 4=-2$

3 4

6 -2

Both graphs are attached below

The graph of f(x) and g(x) interests at x= -1 and x=8.1

Simplify the following rational expression without using a calculator: (12².6³.5²)/(18².15).

prohojiy [21]

Answer:

160

Step-by-step explanation:

$\dfrac{12^2\cdot 6^3\cdot 5^2}{18^2\cdot 15}=\dfrac{(2^2\cdot 3)^2\cdot (2\cdot 3)^3\cdot 5^2}{(2\cdot 3^2)^2\cdot (3\cdot 5)}\\\\=\dfrac{(2^4)(3^2)(2^3)(3^3)(5^2)}{(2^2)(3^4)(3)(5)}=(2^{4+3-2})(3^{2+3-4-1})(5^{2-1})=32\cdot 5\\\\=\bf{160}$

answer

11.3 cm

steps

what is h cm to angle 37°=it is an opposite side

what is 15 cm to angle 37°=it is an adjecent side

opposite and adjecent form a tan

.°. opp/adj = tan(37°)

h/15 = tan(37°)

h = 11.3 cm
