Answer: x=40/3

Step-by-step explanation: 12=0.9x

0.9x=12

0.9x(10)=12(10)

9x/9=120/9

x=40/3

The height of water shooting from a fountain is modeled by the function f(x) = −4x2 + 24x − 29, where x is the distance from the

Komok [63]

Answer:

the maximum height of the water is 7 ft

Step-by-step explanation:

Using " ^ " to indicate exponentiation, we have −4x^2 + 24x − 29.

Rewrite -4x^2 + 24x as -4(x^2 - 6x) and then complete the square of (x^2 - 6x). We get:

(x^2 - 6x + 9 - 9), which is exactly equivalent to (x^2 - 6x).

Going back to the original equation: −4x^2 + 24x − 29, or

−4(x^2 - 6x) − 29.

Now replace (x^2 - 6x) with (x^2 - 6x + 9 - 9):

-4(x^2 - 6x + 9 - 9) - 29, which simplifies to:

-4(x - 3)^2 + 36 - 29, or

-4(x - 3)^2 + 7, whose vertex is (3, 7). Thus, the maximum height of the water is 7 ft.

Answer:

$7$

Step-by-step explanation:

Because the leftmost triangle is a 45-45-90 isosceles right triangle, $a = b =\frac{7\sqrt2}{\sqrt2} = 7\\$

The rightmost triangle is a 30-60-90 triangle, and the side lengths are in the proportion $1:\sqrt3:2$ from shortest to longest. Therefore, $c = 7\cdot\frac{\sqrt3}{1} = 7\sqrt{3} \implies \boxed{7}$
