IF=2x+2, IZ=2x+12 solve for x
Digiron [165]
ANSWER

The value of x is

9


EXPLANATION

F is the point of intersection of the medians of the triangle,

The ratio is

IF:IZ=2:3


This implies that,

(2x + 2): (2x + 12) = 2: 3


We can write this as a fraction to get,

\frac{2x + 2}{2x + 12}  =  \frac{2}{3}


We cross multiply to get,

3(2x  + 2) = 2(2x + 12)

Let us expand the brackets yo obtain,

6x + 6 = 4x + 24


We group like terms to get,

6x - 4x = 24 - 6


2x = 18


We divide both sides by 2 to get,

x = 9

The correct answer is B.

Lim x—&gt; -2 <br> sqrt(3x+10) -2/ x+2
snow_lady [41]

\displaystyle\lim_{x\to-2}\frac{\sqrt{3x+10}-2}{x+2}

Rationalize the numerator:

\dfrac{\sqrt{3x+10}-2}{x+2}\cdot\dfrac{\sqrt{3x+10}+2}{\sqrt{3x+10}+2}=\dfrac{(3x+10)-4}{(x+2)(\sqrt{3x+10}+2)}=\dfrac3{\sqrt{3x+10}+2}

where the x+2 factors in the numerator and denominator cancel. Then the limit is

\displaystyle\lim_{x\to-2}\frac{\sqrt{3x+10}-2}{x+2}=\lim_{x\to-2}\frac3{\sqrt{3x+10}+2}=\frac3{\sqrt4+2}=\boxed{\frac34}

The minute hand of a clock is 8 inches long and moves from 12 to 2 o'clock how far does the top of the minute hand move? express
oksano4ka [1.4K]
The perimeter in 60 minutes is:
 2 * pi * r
 2 * pi * 8
 50.26548246 inches
 It moves from 12 to 2:
 The perimeter will be:
 (10/60) * (50.26548246)
 Rewriting:
 = (2/12) * (50.26548246)
 = (1/6) * (50.26548246)
 = 8.37758041
 round to two-decimal places:
 = 8.38 inches
 Answer:
 the top of the minute hand moves 8.38 inches
