Answer:

Step-by-step explanation:

2x² - 4x - 3 = 0

$x= \frac{-b+/-\sqrt{b^{2}-4ac} }{2a} \\\\x= \frac{-(-4)+/-\sqrt{(-4)^{2}-4*2*(-3)} }{2*2} \\\\x= \frac{4+/-\sqrt{16+24} }{4} \\\\x= \frac{4+/-\sqrt{40} }{4} = \frac{4+/-2\sqrt{10} }{4}=\frac{2+/-\sqrt{10} }{2}$

Answer:

SA = 2520 ft^2

Step-by-step explanation:

a = 21ft

b = 29ft

c = 20ft

h = 30ft

SA = 2 $A_{B}$ + (a+b+c)h

$A_{B}$ = s(s﹣a)(s﹣b)(s﹣c)

s = $\frac{a + b + c}{2}$

SA= ah + bh + ch + $\frac{1}{2}$ $\sqrt{-a^4 + 2(ab)^2 + 2(ac)^2 - b^4 + 2(bc)^2 - c4}$

SA= (21 * 30) + (29 * 30) + (20 * 30) +

$\frac{1}{2}$ $\sqrt{-(21)^4 + 2(21 * 29)^2 + 2(21 * 20)^2 - (29)^4 + 2(29 * 20)^2 - (20)^4}$

SA = 2520 ft^2

Is {(-5,1),(4,9),(6,10)} a function

sladkih [1.3K]

Yes it is a function!, all the first numbers are none repeating, for example it says -5,4,6 since they are not the same this is a function
