One day an e-mail is sent to 7 people. That day each person who receives the e-mail sends the email to two friends. Each friend who receives the email sends it to two more people on the following day

Answers

On the second day 28 people will have received the email.

Exponential functions

To determine the expression that graphs this situation and determine the number of people who will have received the e-mail, the following calculation must be made:

X = Number of days the email is forwarded.7 x 2^X = People who would have received the e-mail.

Thus, if the email is forwarded two days in a row, this formula operates as follows:

7x2^2 = X7 x 4 = X28 = X

Therefore, on the second day 28 people will have received the email.

A pentagon has angle measures of 105°, 101°, 112° and 113°. What must the fifth angle measure?

The fifth angle measures is what?

Answers

Add them. Pentagram interior angle is 540. 105+101+112+113=431. 540-431=109 Hence, 109 is the answer. Please brainliest.

Answer:

109

Step-by-step explanation:

Pentagon can be represented with 3 triangles:

A+B+C+D+E=3×180

105+101+112+113+E=540 => E=109

I need to figure out how exactly to solve this and find the answer to x

Answers

Answer:

Since a triangle has 180 interior degrees, and 81+57=138, and 180-138=42, you need to find _*2+18=42. (Hint, you can subtract the 18 from the 42, and find _*2=24).

Pemba is 5 yrs older than her sister.If the sum of their ages is 35 yrs, find their ages

Answers

his sister 15 and he 20

Answer:

Pemba is 20 and her sister 15

Step-by-step explanation:

Let the sisters age be x. As pemba is five years older, her age is x+5.

Now, the sum of their ages is 135. So, by combining the two ages we get:

=>X+(x+5)=35

x+x+5=30

2x=30

x = 15

Then, substitituing this value of x into our equations for the ages of the sisters we get

sisters age 15 years old

Pemba age (15)+5=20 years old

Trust me I took the test right now

The accurate angle relationships are (b) <1 = <3 and <4 = <6

When a transversal cuts through parallel lines, it forms pairs of congruent angles that are related by several relationships.

From the parallel lines l and m, we have the following angles:

Angle 1 = Angle 3

Angle 4 = Angle 6

Hence, the accurate angle relationships are (b) <1 = <3 and <4 = <6

What is the equation in point-slope form of the line that passes through the point (-5, 6) and has a slope of 2/3

Answers

Answer:

y - 6 = ²/₃(x + 5)

Step-by-step explanation:

The point-slope form of the equation of a line: y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.

m = ²/₃

(-5, 6) ⇒ x₁ = -5, y₁ = 6

So the point-slope form of the equation:

y - 6 = ²/₃(x - (-5))

or: y - 6 = ²/₃(x + 5)

In the xy-plane, a circle with center at point (6,-8) has a radius of 20 units. If the radius of the circle is halved, which of the following points will NOT be inside the circle?

A) (-1/20 , 0)
B) (1/20 , 0)
C) (-1/10 , -6)
D) (8 , 10)

Answers

D) (8, 10) because with a radius of units, anything with a y value higher than 8 is outside the circle

There is a circle with the center [tex](6,-8)[/tex] and radius = [tex]20[/tex] units

We have to find whether the points given in the options will not lie inside the circle if the radius of the circle is halved.

"If a point lies inside the circle, distance between the center and the given point will be less than the radius of the circle".

To find the distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

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

If a point lies inside the circle with radius 10 units, distance between the point and the center will be less than 10 units.

Option A

Distance between the points [tex](-\frac{1}{20},0)[/tex] and [tex](6, -8)[/tex]

= [tex]\sqrt{(6+\frac{1}{20})^2+(-8-0)^2}[/tex]

= [tex]\sqrt{100.6025}[/tex]

= [tex]10.03[/tex] units

Since, [tex]10.03>10[/tex] units

Therefore, [tex](-\frac{1}{20},0)[/tex] will lie outside the circle.

Option B

Distance between [tex](\frac{1}{20},0)[/tex] and [tex](6,-8)[/tex] = [tex]\sqrt{(6-\frac{1}{20})^2+(-8-0)^2}[/tex]

= [tex]\sqrt{99.4025}[/tex]

= [tex]9.97[/tex] units

Since, [tex]9.97<10[/tex] units

Therefore, [tex](\frac{1}{20},0)[/tex] will lie inside the circle.

Option C

Distance between [tex](-\frac{1}{10},-6)[/tex] and [tex](6,-8)[/tex] = [tex]\sqrt{(6+\frac{1}{10})^2+(-6+8)^2}[/tex]

= [tex]\sqrt{41.21}[/tex]

= [tex]6.42[/tex] units

Since, [tex]6.42<10[/tex] units

Therefore, [tex](-\frac{1}{10},-6)[/tex] will lie inside the circle.

Option D

Distance between [tex](8,10)[/tex] and [tex](6,-8)[/tex] = [tex]\sqrt{(8-6)^2+(10+8)^2}[/tex]

= [tex]\sqrt{328}[/tex]

= [tex]18.11[/tex] units

Since, [tex]18.11>10[/tex] units

Therefore, [tex](8, 10)[/tex] will lie outside the circle.

Now we can conclude that [tex](-\frac{1}{20},0)[/tex] and [tex](8,10)[/tex] will lie outside the circle.

Options (A) and (D) will be the correct options.
