Answer:
91
Step-by-step explanation:
Multiplication first, so 7x4 = 28
28+63=91
I've heard of milliseconds, microseconds and nanoseconds, but never a megasecond. By the way:
<span>1 second = 1000 milliseconds </span>
<span>1 second = 1,000,000 microseconds </span>
<span>1 second = 1e+009 nanoseconds
</span>
Trinomial 2x² + 4x + 4.
It's of the form ax²+bx+c and it's discriminant is Δ=b² - 4.a.c
(in our case Δ = 4² - (4)(2)(4) → Δ = - 32
We know that: x' = -1 + i and x" = -1 - i
If Δ > 0 we have 2 rational solutions x' and x"
If Δ = 0 we have1 rational solution x' = x"
If Δ < 0 we have 2 complex solutions x' and x", that are conjugate
In our example we have Δ = - 16 then <0 so we have 2 complex solutions
That are x'= [-b+√Δ]/2.a and x" = [-b-√Δ]/2.a
x' =
Answer:
19.44
Step-by-step explanation:
We have the following information:
3 red balls, 5 green balls, and 1 yellow ball
In total there are 3 + 5 + 1 = 9 balls.
We calculate the probability of each:
Network: 3/9
Green: 5/9
Yellow: 1/9
Each one corresponds a price in profit or losses:
Network: 4
Green: -3
Yellow: 10
So in total it would be the sum of the multiplication of the probability and the price and then multiply everything by 25:
(4 * 3/9 + -3 * 5/9 + 10 * 1/9) * 25 = (0.777) * 25
= 19.44
Step-by-step explanation:
b) y=x+1
table:
_x _|_2x_|_y_|(x, y)|
0 |2(0) |1 |(0, 1)|
1 | 2(1) |2 |(1, 2)|
2 | 2(2) |3 |(2, 3)|
3 | 2(3) |4 |(3, 4)|
c) y=3x+2
_x _|_2x_|_y_|(x, y)|
0 |2(0) |2 |(0, 2)|
1 | 2(1) |5 |(1, 5)|
2 | 2(2) |8 |(2, 8)|
3 | 2(3) |14 |(3, 14)|
To graph, plot the x, y points and connect all of them
