Step-by-step explanation:

The probability of an event happening is between 0 and 1 inclusive.

How would I find the Max/min of this function f(x) = 2x squared +18x +16
slamgirl [31]
F(x)=2x²+18x+16
1) we have to calculate the first derived.

f´(x)=4x+18

2) Now, we equalize the first derived to "0" and find out the value of "x"
4x+18=0
4x=-18
x=-18/4=-4.5

3)we calculate the second derived
f´´(x)=4>0  ⇒we have a minimum at x=-4.5

4) Now we calculate the value of "y".
f(-4.5)=2(-4.5)²+18(-4.5)+16=40.5-81+16=-24.5

Therefore; Exist a minimum at (-4.5 , -24.5)

Help me pls it’s urgent
earnstyle [38]

Answer:

<A = 115

<C = 50

Step-by-step explanation:

<A + <B + <C = 180

SO

(4X -13) +15 +(X+18) =180

5X +20 =180

5X = 160

X= 32

LOG IN TO <A = 4*32 -13 = 115

<C = 32+18 = 50

(3-20i)-(14+6i)-(8-2i)
ollegr [7]

Because there are parentheses we distribute the negative signs:

3 - 20i + (-14) - 6i + (-8) + 2i

Next combine like terms:

3 + (-14) + (-8) and -20i - 6i + 2i

-19 -24i
