x,y, and z to the nearest tenth .(hint: use altitude and leg rules) PLEASE HELP FAST !!! please solve and show steps

madreJ [45]

Use the Pythagorean theorem to find z:

z = √(6^2 + 9^2)

z= √(36 + 81)

z = √117

z = 3√13 = 10.8

Use leg rule to find x:

x/6 = 6/9

Cross multiply:

9x = 36

Divide both sides by 9:

x = 36/9

x = 4

Use Pythagorean theorem to find y:

y = √(6^2 + 4^2)

y= √(36 + 16)

y = √52

y = 2√13 = 7.2

Find the difference quotient of f(x)=5x+4

Aleonysh [2.5K]

The differnce quotient is basically taking the derivitive (result will be f'(x)=5, but anyway)

here is the disffernce quotient
$lim_{h\rightarrow0}\frac{f(x+h)-f(x)}{h}$

so
for your equation
$lim_{h\rightarrow0}\frac{(5(x+h)+4)-(5x+4)}{h}$
$lim_{h\rightarrow0}\frac{5x+5h+4-5x-4}{h}$
$lim_{h\rightarrow0}\frac{5h}{h}$
h's cancel and you are left with 5
the differnce quotient is 5
