In this picture B and F are
midpoints.
x=[ ? ]

Answers

Answer 1

Answer: x = 10

see in the picture, ΔACE has:

+) BF//AE

+) B and F are midpoints.

=> BF is the median line of the triangle ACE

=> BF = 1/2. AE

=> AE = 2BF

⇔ 5x - 4 = 2.23 = 46

⇔ 5x = 46 + 4 = 50

⇔ x = 50/5 = 10

need help.. The midpoint of GH is M(-6,-3). One endpoint is H (-4,4) Find the coordinates of endpoint G.

Answers

Answer:

The coordinates of G are: (-8, -10)

Step-by-step explanation:

Mid point formula:

[tex]x = \dfrac{x_1+x_2}{2}\\y = \dfrac{y_1+y_2}{2}[/tex]

Where,

[tex](x,y)[/tex] are the coordinates of the mid point of the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex].

As per question statement, we are given that:

[tex]x_2=-4\\y_2=4[/tex]

and

[tex]x=-6\\y=-3[/tex]

To find:

[tex]x_1 = ?\\y_1 = ?[/tex]

Solution:

Let us use the mid point formula:

[tex]-6 = \dfrac{x_1-4}{2}\\\Rightarrow -12=x_1-4\\\Rightarrow x_1=-12+4\\\Rightarrow \bold{x_1=-8}[/tex]

[tex]-3 = \dfrac{y_1+4}{2}\\\Rightarrow -6=y_1+4\\\Rightarrow y_1=-6-4\\\Rightarrow \bold{y_1=-10}[/tex]

The coordinates of G are: (-8, -10)

What is the rate of change for the line that goes through the points (8,14) and (11, 19.25)

Answers

Answer:

1.75

Step-by-step explanation:

The rate of change for the line that goes through the points (8,14) and (11, 19.25) is known as the slope expressed as;

slope m = y2-y1/x2-x1

Substitute the coordinate pairs into the formula;

m = 19.25-14/11-8

m = 5.25/3

m = 1.75

Hence the rate of change for the line is 1.75.

Answer:

9:5

Step-by-step explanation:

112 - 40 = 72. 112 represents the total time, but you are comparing music to commercials, so you have to subtract the commercial time from the total time.Find the GCF of 72 and 40, which is 8. Divide 72 and 40. The simplified ratio is 9:5.

The hours a week people spend answering and sending emails is normally distributed with a standard deviation of Ï = 150 minutes. How large of a sample size would you need to estimate the mean number of minutes people spend answering and sending emails with an error of 1 minutes with 99% confidence? What would be the practical problem with attempting to find this confidence interval?

Answers

Answer:

sample size n would be 149305 large

Value of n (149305) is too high, this will be the practical problem with attempting to find this confidence interval

Step-by-step explanation:

Given that;

standard deviation α = 150 min

confidence interval = 99%

since; p( -2.576 < z < 2.576) = 0.99

so z-value for 99% CI is 2.576

E = 1 minutes

Therefore

n = [(z × α) / E ]²

so we substitute

n = [(2.576 × 150) / 1 ]²

n = [ 386.4 ]²

n = 149304.96 ≈ 149305

Therefore sample size would be 149305 large

Value of n is too high, that would be the practical problem with attempting to find this confidence interval

Use the skills demonstrated in this lesson to define any unfamiliar words and make sure you understand the passages main ideas.Cold gas falls toward the central black hole, like water entering the pump of a fountain. Some of this infalling gas . . . eventually reaches the vicinity of the black hole, where the black hole's gravity causes the gas to swirl around with ever-increasing speeds, and the gas is heated to temperatures of millions of degrees. This swirling motion also creates strong electromagnetic forces that launch high-velocity jets of particles that shoot out of the galaxy.What is the MOST accurate summary of this excerpt?A)Cold gas moves rapidly toward the black hole. When it is close enough to be affected by the black holes gravity, the gas begins to pulse faster and faster as it becomes very hot. The pulsing motion produces forces from the electric field that cause particles to bounce around the galaxy at very low speeds.B)Cold gas moves toward the black hole. When it is close enough to be affected by the black holes gravity, the gas begins to swirl faster and faster as it becomes very hot. The swirling motion produces forces from the electric and magnetic fields that cause particles to shoot out of the galaxy at very high speeds.C)Cold gas moves slowly toward the black hole. When it is close enough to be affected by the black holes gravity, the gas begins to flare up and becomes very cold. The flares produce forces from the magnetic field that cause particles to shoot out of the galaxy at very moderate speeds.D)Hot gas moves toward the black hole. When it is close enough to be affected by the black holes gravity, the gas begins to build up and it becomes very bright. This buildup produces forces from the electric and magnetic field that cause particles to disappear into the galaxy in a matter of seconds. Fill in the blanks with proper or common noun.1.
