Use the pythagorean theorem (a^2 + b^2 = c^2)

4^2 + 4^2 = c^2

16+ 16 = c^2

32 = c^2

sqrt(32) = c

The third option you have listed is the right answer (its 4sqrt(2) simplified)

Hello can someone please help me in these question please?

Andrej [43]

Answer:

Answer: B

Step-by-step explanation:

$f(x) = \frac{12}{x} - 18 \\$

let its inverse be m :

$m = \frac{12}{x} - 18 \\ \\ m + 18= \frac{12}{x} \\ \\ x = \frac{12}{m + 18} \\ \\ { \boxed{ \boxed{f {}^{ - 1}(x) = \frac{12}{x + 18} }}}$

Solve the equation x^2+17x+12=-3x^2 to the nearest tenth.

mote1985 [20]

Answer:

$x=-\frac{17}{8}+\frac{\sqrt{97} }{8}$ or $x=-\frac{17}{8}-\frac{\sqrt{97} }{8}$

Step-by-step explanation:

$x^2+17x+12=-3x^2$

Add $3x^2$ on both sides.

$x^2+17x+12+3x^2=-3x^2+3x^2$

$x^2+17x+12+3x^2=0$

Combine like terms;

$4x^2+17x+12=0$

Use the quadratic formula;

a=4

b=17

c=12

$x=\frac{-b\frac{+}{}\sqrt{b^2-4ac} }{2a}$

$x=\frac{-(17)\frac{+}{}\sqrt{(17)^2-4(4)(12)} }{2(4)}$

$x=\frac{-17\frac{+}{}\sqrt{289-192} }{8}$

$x=\frac{-17\frac{+}{}\sqrt{97} }{8}$

$x=-\frac{17}{8}+\frac{\sqrt{97} }{8}$ or $x=-\frac{17}{8}-\frac{\sqrt{97} }{8}$

Clayton is at most 2 meters above sea level. Using C for Clayton, which inequality correctly represents this statement?

Nataly [62]

Answer:

C ≤ 2

Step-by-step explanation:

Given that :

Clayton is at most 2 meters above sea level ;

Let Clayton = C

Clayton's distance can be represented by the inequality :

2 meters above sea level is positive, +2

At most 2 meters above sea level means, Clayton could be anywhere between + 2 metwrs but not more than 2 meters

Hence, Clayton's distance can be represented by the inequality :

C ≤ 2
