Enter the letters of the points that lie on the line $y = \frac{1}{2} x + 3.$[asy]unitsize(0.4 cm);pair A, B, C, D, E, F, G, H,
igor_vitrenko [27]

The points that lie on the line are C(-4, 1), E(-6, 6) and  I(2, 4)

Given the equation of a line expressed as y=\frac{1}{2}x + 3

We need to find which of the points from A to J lies on the line.

To do that, we will substitute the x-coordinate point into the equation to see if we are going to get the y-coordinate

For the coordinate C(-4, 1)

when x = -4

y = 1/2(-4) + 3

y = -2 + 3

y = 1

This shows that the point C(-4, 1) is on the line

For the point E(6, 6)

when x = 6

y = 1/2(6) + 3

y = 3 + 3

y = 6

This shows that the point E(-6, 6) is on the line

For the point I (2, 4)

when x = 2

y = 1/2(2) + 3

y = 1 + 3

y = 4

This shows that the point I(2, 4) is on the line

This shows that the points that lie on the line are C(-4, 1), E(-6, 6) and  I(2, 4)

Which of the following lists the three named stars in order of increasing mass (lowest mass first)?
Helga [31]

Answer:

Option (A)

Step-by-step explanation:

The Barnard's Star is usually considered to be a red dwarf, that is approximately six light-years away from the location of earth. It is present in the Ophiuchus constellation and forms the 4th proximate star to the sun.

Altair refers to the bright shining star present in the Aquila constellation. It forms the 12th brightest star that occurs in the night sky.

Spica is one of the proximate stars to the earth and that is extremely large having a mass of almost ten times the mass of the sun.

The mass of Barnard's star is= 2.864 × 10^29 kg

The mass of the Altair is= 3.56 × 10^30 kg

The mass of the Spica= 19.89 × 10^30 kg

The arrangement of these given stars in the increasing order are as follows-

Barnard's star (minimum) < Altair star < Spica star (maximum)

Hence, the correct answer is option (A).

16. How much money will I need to have at retirement so I can withdraw $60,000 a year for 20 years from an account earning 8% co
Lady_Fox [76]

Answer:

  • starting balance: $636,215.95
  • total withdrawals: $1,200,000
  • interest withdrawn: $563,784.05

Step-by-step explanation:

a) If we assume the annual withdrawals are at the beginning of the year, we can use the formula for an annuity due to compute the necessary savings.

The principal P that must be invested at rate r for n annual withdrawals of amount A is ...

  P = A(1+r)(1 -(1 +r)^-n)/r

  P = $60,000(1.08)(1 -1.08^-20)/0.08 = $636,215.95

__

b) 20 withdrawals of $60,000 each total ...

  20×$60,000 = $1,200,000

__

c) The excess over the amount deposited is interest:

  $1,200,000 -636,215.95 = $563,784.05
