What is the standard form of a quadratic with a root of
[tex]2i \sqrt{3} [/tex]
​

I am so sorry i cant help but good luck

Answer:

D.77

Step-by-step explanation:

I forgot the technical name, but basically the measure of the angle is half of the arc.

For example 90 + 64 is 154, so half that is 77.

Good Luck!

Step-by-step explanation:

Answer:

r = -23

Step-by-step explanation:

A slope of 1/2 means that for every y-value increase of 1, the x value will increase by 2.

Between -7 and 5, there was an increase of 12. So, the x value will increase by 24.

To find r, subtract 24 from 1

1 - 24

= -23

So, r = -23

Answer:

Number of Bacteria, B(t)   2    4      8      16

Step-by-step explanation:

To find the B(t) values when t equals 0 through 3, look at the diagram and count the number of bacteria: when t is 0, B(t) is 2, when t is 1, B(t) is 4; when t is 2, B(t) is 8; and when t is 3, B(t) is 16.

Every second of video time equals 20 minutes of real time. So, one hour, or 60 minutes, of real time is 3 seconds of video time, which results in 16 bacteria.

Number of Bacteria, B(t)   2    4      8      16

The total number of bacteria after the first hour(60 minutes) is 16.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

According to the question

He is taking screenshots of the video after every second of video time, with each second of video time correlating to 20 minutes of real time.

In the video, each bacteria cell splits into two cells with each passing second, as seen in the images from the video.

To find the B(t) values when t equals 0 through 3, look at the diagram and count the number of bacteria: when t is 0, B(t) is 2, when t is 1, B(t) is 4; when t is 2, B(t) is 8; and when t is 3, B(t) is 16.

Every second of video time equals 20 minutes of real time. So, one hour, or 60 minutes, of real time is 3 seconds of video time, which results in 16 bacteria.

Number of Bacteria, B(t)   2    4      8      16

Hence,

The total number of bacteria after the first hour(60 minutes) is 16.

Answer:

y = 1/4x + 7

Step-by-step explanation:

A perpendicular line will have an opposite reciprocal slope, so the slope will be 1/4

Plug in the given point and slope into y = mx + b, then solve for b

y = mx + b

5 = 1/4(-8) + b

5 = -2 + b

7 = b

Plug in b and the slope into y = mx + b

y = 1/4x + 7

So, the equation of the line is y = 1/4x + 7

Answer:

6i

Step-by-step explanation:

Answer:

16 units

Step-by-step explanation:

We need to find the distance between (-4, 8) and (12, 8) on the coordinate plane.

We know that the distance between two points on the coordinate plane is given by :

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Put x₁ = -4, x₂ = 12, y₁ = 8 and y₂ = 8

So,

[tex]D=\sqrt{(12-(-4))^2+(8-8)^2}\\\\=16\ units[/tex]

So, the distance between the two points is equal to 16 units.

Answer:

We know length of one quarter of a circle = 2πr/4 = πr/2

So here we can make the equation for to find thr value of radius r

length of one quarter given = 25 cm

so πr/2 = 25 cm

=> πr = 50 cm

=> r = 50/π cm

So the entire circumference of circle =

2πr

= 2 π 50/π cm

= 100π/π cm (ans)

Here we dont substitute the value of π due to represent the answer in terms of pi.

Answer:

Angular velocity: [tex]\omega = \frac{7\pi}{18} \,\frac{rad}{s}[/tex] ([tex]1.222\,\frac{rad}{s}[/tex])

Linear velocity: [tex]v = \frac{14\pi}{3}\,\frac{m}{s}[/tex] ([tex]14.661\,\frac{m}{s}[/tex])

Step-by-step explanation:

The gear experiments a pure rotation with axis passing through its center, the angular ([tex]\omega[/tex]), in radians per second, and linear velocities ([tex]v[/tex]), in inches per second, of a point on the outer edge of the element are, respectively:

[tex]\omega = \frac{2\pi}{60}\cdot \dot n[/tex] (1)

[tex]v = R\cdot \omega[/tex] (2)

Where:

[tex]\dot n[/tex] - Rotation rate, in revolutions per minute.

[tex]R[/tex] - Radius of the gear, in inches.

If we know that [tex]\dot n = \frac{35}{3}\,\frac{rev}{min}[/tex] and [tex]R = 12\,in[/tex], then the linear and angular velocities of the gear are, respectively:

[tex]\omega = \frac{2\pi}{60}\cdot \dot n[/tex]

[tex]\omega = \frac{7\pi}{18} \,\frac{rad}{s}[/tex] ([tex]1.222\,\frac{rad}{s}[/tex])

[tex]v = R\cdot \omega[/tex]

[tex]v = \frac{14\pi}{3}\,\frac{m}{s}[/tex] ([tex]14.661\,\frac{m}{s}[/tex])

When x=6

f(6) =(6)2-2(6)=12-12=0

Answer:

firstly... substitute x for 6 in the equation..

=(6)2 -2(6)

=12-12=0

103 + 38 = 141

180 - 141 = 39

The third angle is 39 degrees.
