8.4 dhndyshshsjsjs yup that’s it’s 778 it indicates
You can calculate that as (x * 50)/100 = 37
x*50 = 3700
x=74
Answer:
is there a figure for this question?
Answer:
Solutions are 2, -1 + 0.5 sqrt10 i and -1 - 0.5 sqrt10 i
or 2, -1 + 1.58 i and -1 - 1.58i
(where the last 2 are equal to nearest hundredth).
Step-by-step explanation:
The real solution is x = 2:-
x^3 - 8 = 0
x^3 = 8
x = cube root of 8 = 2
Note that a cubic equation must have a total of 3 roots ( real and complex in this case). We can find the 2 complex roots by using the following identity:-
a^3 - b^3 = (a - b)(a^2 + ab + b^2).
Here a = x and b = 2 so we have
(x - 2)(x^2 + 2x + 4) = 0
To find the complex roots we solve x^2 + 2x + 4 = 0:-
Using the quadratic formula x = [-2 +/- sqrt(2^2 - 4*1*4)] / 2
= -1 +/- (sqrt( -10)) / 2
= -1 + 0.5 sqrt10 i and -1 - 0.5 sqrt10 i
Answer:
140 feet
Step-by-step explanation:
If the first time she dropped the ball was from 160 feet then the second time she dropped the ball is would bounce back up 80 feet. The third time it would bounce 40 feet. And the 4th time it would bounce 20 feet
So the total distance the ball traveled from the first time it hit the ground is 140 feet
