Answer:
The values of x are x= 2i and x= -2i
Step-by-step explanation:
We need to solve the equation:
2x^2 + 8 =0
Taking 2 common
2(x^2 +4) =0
Dividing both sides by 2
x^2+4 =0
Adding -4 on both sides
x^2 +4 -4 = 0-4
x^2 = -4
Taking square root on both sides we get
√x^2 = √-4
we know √4 = 2 and √-1 = i so answer is:
x = ± 2i
The values of x are x= 2i and x= -2i
The graph is shown in figure attached.
Answer: 4
Step-by-step explanation:
Since it's the absolute value of -12 then it turns positive always so 12 - 8 equals 4
In 805 tens this would result to 8,050 wherein 805 is multiplied by 10.
In using the place value chart, you put the 5 in the tens place still resulting to 8,050.
Therefor, eight thousands and 0 hundreds and 5 tens and 0 ones.
Answer:
Cos C = a/h
= 21/35
Step-by-step explanation:
since cos is equal to adjacent angle over hypotenuse angle, so from the question we conclude Cos C = 21/35
Step-by-step explanation:
could the conditional statement be written in another way
