Pls answer this quick! Thank you!

Answer:

+/- 8i

Step-by-step explanation:

x^2 = -64

square root (x^2) = square root of (-64)

x =  +/- 8* the square root of (-1)

x = plus or minus 8i

The solution for the given quadratic equation are 8i and -8i.

The given quadratic equation is x²=-64.

A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z.

Here, square root on both the sides of an equation

That is, x=√(-64)

Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.

= ±8i

Therefore, the solution for the given quadratic equation are 8i and -8i.

The area of given figure is, 35 meter².

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

We have to given that;

The figure is shown in figure.

Now, We know that;

⇒ Area of rectangle = Length × Width

So, The area of figure is,

⇒ 9 × 3 + (7 - 3) × 2

⇒ 27 + 4 × 2

⇒ 27 + 8

⇒ 35 meter²

Answer:

$3.23

Step-by-step explanation:

Given that,

Principal, P = $2,000

Rate of interest, r = 1.96%

Tie, n = 1 month = (1/12) years

The formula of compound interest is given by :

[tex]CI=P[(1+\dfrac{R}{100})^n-1]\\\\CI=2000\times [(1+\dfrac{1.96}{100})^{1/12}-1]\\\\CI=3.23[/tex]

So, the interest will she earn at the end of 1 month is $3.23

The amount she earns at the end of 1 month is 200,326cents

The formula for calculating the compound amount is given as:

A = 2000(1 + 0.0196/12)^(12*1/12)

A = 2000 (1+0.00163)^1

A = 2000(1.00163)

A = $2,003.26

Hence the amount she earns at the end of 1 month is 200,326cents

Answer:

5km/hr

Step-by-step explanation:

Given

Distance = 3km and 2km

Time = 30 mins, 15 mins, 15 mins

Required

Determine the average speed

To answer this, we need to determine the total distance.

Distance =3km + 2km = 5km

Then, we calculate the total time

Time = 30 mins + 15 mins + 15 mins = 1 hr

Next, we can now determine the average speed using:

Average Speed = Total Distance/Total Time

Average Speed = 5km/1 hr

Average Speed = 5km/hr

Step-by-step explanation:

Answer:

A. A rotation of 72º around the center, point D.

C. A reflection across line b through one vertex, the center d.

E. A reflection across line c, and the midpoint of the opposite side

Step-by-step explanation:

From Euclidean Geometry we get that sum of internal angles inside a polygon equals 360º and there is the following relationship in regular polygons:

[tex]\theta = \frac{360^{\circ}}{n}[/tex] (Eq. 1)

Where:

[tex]\theta[/tex] - Internal angle, measured in sexagesimal degrees.

[tex]n[/tex] - Number of sides, measured in centimeters.

If we know that [tex]n = 5[/tex], then internal angle of regular pentagon is:

[tex]\theta = \frac{360^{\circ}}{5}[/tex]

[tex]\theta = 72^{\circ}[/tex]

In consequence, rotating the regular pentagon 72º around the pentagon carries the figure onto itself due to angular symmetry. (Correct answer: A)

By adding any line passing the center of the regular pentagon (i.e. line cc', line bb'), which is collinear to any vertex and any point of the figure, we guarantee conditions of length symmetry so that reflection carries the figure onto itself. (Correct answers: C, E)

Answer:

1.7n +28.5

Step-by-step explanation:

you compare like terms first

1.5n add it to 2n

it will equal to 1.7

then add 16.5 to 12

it will equal to 28.5

Your new equation will be

1.7n+ 28.5 if it was equal to something let's say it was equal to 180 as an example:

your equation will be

1.7n + 28.5= 180

-28.5= -28.5

1.7n= 151.5 you would divide it

it would equal 89.1 and change.

  y = mx +b

  y = -x +b . . . . . with the coefficient of x filled in

  -4 = -(3) +b . . . with the given point filled in

  b = -1 . . . . .add 3 to both sides
