Answer:
√35i
Step-by-step explanation:
i is an imaginary number. It represents the square root of negative one. By pulling it out, we pull out the negative, and our answer uses the unit i. Because 35 cannot be simplified, we are done.
Answer:
We know that √-1 = i, where "i" is the imaginary unit
± √(-35) = ± √(35) i
± √(35) i is the right answer.Related Questions
Solve the equation
x2 + 4x - 7 = 0
by completing the square.
Give your answers correct to 2 decimal places.
Answers
Answer:
x ≈ - 5.32, x ≈ 1.32
Step-by-step explanation:
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2) x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ± [tex]\sqrt{11}[/tex] ( subtract 2 from both sides )
x = - 2 ± [tex]\sqrt{11}[/tex]
Then
x = - 2 - [tex]\sqrt{11}[/tex] ≈ - 5.32 ( to 2 dec. places )
x = - 2 + [tex]\sqrt{11}[/tex] ≈ 1.32 ( to 2 dec. places )

Find the 25th term in the arithmetic sequence: 23, 223, 423, 623,...
Answers
Answer:
Step-by-step explanation:
Assuming that 23 is the first term
4823
25th term of arithmetic sequence is 4,823
Given arithmetic sequence:
23, 223, 423, 623,...
Find:
25th term of arithmetic sequence
Computation:
First term a = 23
Common difference d = A2 - A1
Common difference d = 223 - 23
Common difference d = 200
Number of term n = 25
So,
An = a + (n - 1)d
A25 = 23 + (25 - 1)(200)
A25 = 23 + (24)(200)
A25 = 23 + 4,800
A25 = 4,823

Please help, and plz don't be saying this is the right answer if u dont know for sure.
Answers
The answer you’ll put in the box is 1, because it doesn’t ask you to solve for x, just fill in the number.
Answer:
The blank in the equation is 1.
x = 7 and the vertical angles measure out to 64 degrees.
Step-by-step explanation:
When solving for x, you always want to keep the variables on one side. So you'll subtract 9x from both sides. That gives you 1=3x-20. Then you'll add 20 to both sides. This gives you 21=3x. After you'll divide by 3 on both sides. This gives you 7=x.
Now you'll plug in 7 for x. This gives you 12*7-20=9*7+1. First, you'll multiply which gives you 84-20=63+1. Add and you'll get 64 on both sides.

many years will it be before the man's age is just twice that of
his daughter?
ver:
years
Answers
Answer:
Step-by-step explanation
x+38=2(x+14)
The man is 38 and daughter is 14. They both will age in same years (x).
So, in how many years(x) will they both age until man is equal(=) to 2 times his daughters age?
x+ 38=2(x+14)
x+38=2x+ 28
10= x
In 10 years, the man will be 2twice as old as his daughter.

Which point is the image of (-7,1) reflected across the y-axis? "-enter answer as an ordered pair without
spaces**
Answers
Answer:
The image point of (-7, 1) after reflection across the y-axis is:
(7, 1)Step-by-step explanation:
When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.
Thus,
The rule to reflect a point across the y-axis is:
P(x, y) → P'(-x, y)
In our case, we are given the point (-7, 1)
Let say the point is A(-7, 1).
Thus, using the rule to reflect a point across the y-axis is:
P(x, y) → P'(-x, y)
A(-7, 1) → A'(-(-7), 1) → A'(7, 1)
Therefore, the image point of (-7, 1) after reflection across the y-axis is:
