Answer:
<u>The correct answer is that 4√- 2 is the simplest radical form of this mathematical expression and 8i (i = imaginary unit) is the solution if we want to find out the square root of a negative signed number.</u>
Step-by-step explanation:
1. Let's write in a mathematical expression the information given:
Sum square root of -2 and the square root of - 18
√- 2 + √ - 18
√- 2 + √ 9 . - 2 ( 9 * -2 = - 18)
√- 2 + 3 √ - 2 (√ 9 = 3)
4 √- 2
This is the simplest radical form of this mathematical expression. If we want a concrete number, we should remember that if we refer to the imaginary numbers we can find the solution for √-2 = 2i, or for any other negative number, where i is the imaginary unit. This unit can be used for the development of the square root of negative signed numbers.
Then,
4 √- 2 = 4 (2i) = 8i
<u>The correct answer is that 4√- 2 is the simplest radical form of this mathematical expression and 8i (i = imaginary unit) is the solution if we want to find out the square root of a negative signed number.</u>
Answer:
28
Step-by-step explanation:
AB
4(7)=28
Answer:
The slope is 2
The y-intercept is 3
The equation is y = 2x +3
Step-by-step explanation:
The equation goes up 2 squares and over 1 square. 2/1 = 2
For y-intercept, look at the y-axis
The equation is supposed to be written as y = mx + b
m being the slope and b being the y-intercept.
Answer:
Step-by-step explanation:
n=8 f(x) = x² - 4x
convert [0,2] into 8 subintervals
width of each interval is
All subintervals are:
[0, 0.25], [0.25, 0.5], [0.5, 0.75], [0.75, 1], [1, 1.25], [1.25, 1.5], [1.5, 1.75] and [1.75, 2]
Let, 
be the right end point of each interval i=1,..8
Reiman sum is
![R_8=\delta x[f(x_1)+f(x_2)+...f(8)]\\\\0.25[f(0.25)+f(0.5)+...+f(2)]\\\\0.25\times[-23.25]\\=-5.8125](https://tex.z-dn.net/?f=R_8%3D%5Cdelta%20x%5Bf%28x_1%29%2Bf%28x_2%29%2B...f%288%29%5D%5C%5C%5C%5C0.25%5Bf%280.25%29%2Bf%280.5%29%2B...%2Bf%282%29%5D%5C%5C%5C%5C0.25%5Ctimes%5B-23.25%5D%5C%5C%3D-5.8125)
