How do you find the square root of a negative number? Explain the process

IrinaK [193]

Answer:

A. $\sqrt{-64}$ = 8i

B. 8i + 5i = 13i

C. 8i - 5i = 3i

D. 8i x 5i = -40

Step-by-step explanation:

A. The square root of any negative number would lead to a complex number. Complex numbers are number which consist a complex part denoted by i.

-1 = $i^{2}$

$\sqrt{-1}$ = $\sqrt{i^{2} }$ = i

Example: 1. What is the square root of -64?

square root of -64 = $\sqrt{-64}$

= $\sqrt{-1 *64}$

= $\sqrt{-1}$ x $\sqrt{64}$

= i x 8

= 8i

$\sqrt{-64}$ = 8i

2. find the square root of -25.

$\sqrt{-25}$ = $\sqrt{-1*25}$

= 5i

B. To add two complex numbers, they are considered as algebraic expressions.

Example, the sum of 8i and 5i can be determined as;

8i + 5i = 13i

C. To add two complex numbers, they are considered as algebraic expressions.

Example, the subtraction of 8i and 5i can be determined as;

8i - 5i = 3i

D. To multiply two complex numbers, the complex part is considered.

Example, determine the product of 8i and 5i.

8i x 5i = 8 x 5 x i x i

= 40 $i^{2}$

= -40 (∵ $i^{2}$ = -1)

8i x 5i = -40

Emilie rides her bike x miles before she gets a flat tire. She walks 1/3mile to a bus stop and then takes a bus for 2 1/2miles.

ICE Princess25 [194]

Given :

Emilie rides her bike x miles before she gets a flat tire.

She walks 1/3 mile to a bus stop and then takes a bus for 2 1/2 miles.

To Find :

Which expression shows how many miles Emilie travels in all.

Solution :

We know, total distance covered is given by sum of all the distance she travelled.

Distance covered, D = x + 1/3 + 2 1/2

D = x + 1/3 + 5/2

D = (6x + 2 + 15)/6

D = (6x + 17)/6

Therefore, total distance travelled by Emilie is (6x + 17)/6 .

NEED HELP ASAP 30 POINTS WILL BE GIVEN TO BRAINLIEST

WINSTONCH [101]

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$G(-1,3)\ H(1,2)\ J(-3,-1)$

Step 1

Find the slope GH

$G(-1,3)\ H(1,2)$

substitute in the formula

$m=\frac{2-3}{1+1}$

$m=\frac{-1}{2}$

$mGH=-\frac{1}{2}$

Step 2

Find the slope HJ

$H(1,2)\ J(-3,-1)$

substitute in the formula

$m=\frac{-1-2}{-3-1}$

$m=\frac{-3}{-4}$

$mHJ=\frac{3}{4}$

Step 3

Find the slope JG

$J(-3,-1)\ G(-1,3)$

substitute in the formula

$m=\frac{3+1}{-1+3}$

$m=\frac{4}{2}$

$mJG=2$

Step 4

Verify if triangle GHJ is a right triangle

we know that

if two lines are perpendicular, then the product of their slopes is equal to minus one

$m1*m2=-1$

compare slope GH with slope JG

we have

$mGH=-\frac{1}{2}$

$mJG=2$

$-\frac{1}{2}*2=-1$ -----> side GH and side JG are perpendicular

The triangle GHJ is a right triangle

9 1/3 to a fraction show me

alekssr [168]

Answer:

$\frac{28}{3}$

Step-by-step explanation:

If you mean an improper fraction, then $9\frac{1}{3}=\frac{(9*3)+1}{3}=\frac{27+1}{3}=\frac{28}{3}$
