I want to withdraw 400.00 for 9 years at 8%. How much do I need to deposit

Answers

Answer:

The principal investment required to get a total amount, principal plus interest, of $400.00 from simple interest at a rate of 8% per year for 9 years is $232.56.

Step-by-step explanation:

Given

Total accrued Amount A = 400.00 (Let say $)Time period t = 9 yearsInterest rate r = 8% = 0.08

To determine

Principle P = ?

Using the formula

P = A / (1 + rt)

substituting A = 400.00, t = 9 and r = 0.08 in the formula

P = 400 / ( 1 + (0.08 × 9))

P = $232.56

Therefore, the principal investment required to get a total amount, principal plus interest, of $400.00 from simple interest at a rate of 8% per year for 9 years is $232.56.

Answers

Answer:

[tex]\frac{f(x+h)-f(x)}{h}[/tex][tex]=2x - h[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 8 - x^2[/tex]

Required

Determine: [tex]\frac{f(x+h)-f(x)}{h}[/tex]

First, we calculate f(x + h)

[tex]f(x) = 8 - x^2[/tex]

[tex]f(x+h) = 8 - (x+h)^2[/tex]

[tex]f(x+h) =8- x^2-2xh-h^2[/tex]

So, we have:

[tex]\frac{f(x+h)-f(x)}{h}[/tex] [tex]= \frac{8- x^2-2xh-h^2 - 8 + x^2}{h}[/tex]

[tex]\frac{f(x+h)-f(x)}{h}[/tex] [tex]= \frac{8 - 8 + x^2- x^2-2xh-h^2}{h}[/tex]

[tex]\frac{f(x+h)-f(x)}{h}[/tex] [tex]= \frac{-2xh-h^2}{h}[/tex]

[tex]\frac{f(x+h)-f(x)}{h}[/tex][tex]=2x - h[/tex]

The point
P
is on the unit circle. If the y-coordinate of
P
is

, and
P
is in quadrant IV , then

Answers

If the y-coordinate of P is −3/5, and P  is in quadrant IV, then x = 4/5

How to find the coordinate of a unit circle?

In Trigonometry, the unit circle is a special circle that is centered on the origin of a coordinate grid, with a radius equal to 1 unit.

Now, we are told that the point P is on the unit circle and also we know that the length of the line from P to the origin is exactly 1 unit.

We're also given a y-coordinate as, y = -3/5.

The y-coordinate denotes the length of a perpendicular line from point P to the x-axis.

If x is the x-coordinate, y is the y-coordinate, and h is the hypotenuse length, we can set up the equation vis Pythagoras theorem as:

x² + y² = h²

Making x the subject gives;

x = √(h² – y²)

Plug in the relevant values h = 1 and y = -3/5 to get;

x = √(1)² – (-3/5)²

x = √1 – 9/25

x = √16/25

x = 4/5

We are told that P is in quadrant IV, which has negative values for both y and positive values for x and as such  x is positive.

Thus, x = 4/5

Step-by-step explanation:

Step 1: Define

4y + 4 = 2y - 10

Step 2: Solve for y

[Subtraction Property of Equality] Subtract 2y on both sides:                    2y + 4 = -10[Subtraction Property of Equality] Subtract 4 on both sides:                      2y = -14[Division Property of Equality] Divide 2 on both sides:                                y = -7

Answer:

[tex]y = - 7[/tex]

Step-by-step explanation:

1. Subtract 2y from both sides.

[tex]4y + 4 - 2y = - 10[/tex]

2. Simplify 4y + 4 - 2y to 2y + 4.

[tex]2y + 4 = - 10[/tex]

3. Subtract 4 from both sides.

[tex]2y = - 10 - 4[/tex]

4. Simplify -10 - 4 to -14.

[tex]2y = - 14[/tex]

5. Divide both sides by 2.

[tex]y = - \frac{14}{2} [/tex]

6. Simplify 14/2 to to 7.

[tex]y = - 7[/tex]

Therefor, the answer is, Y = -7

Two-ninths of the bracelet is gray. Since five-ninths of the bracelet is white, four-ninths of the bracelet is red and gray. The word problem says that there is an equal amount of red and gray, so you divide four in half. Two-ninths of the bracelet is gray, two-ninths of it is red, and five-months of it is white.

WILL MARK BRAINIEST!!!IK ITS A LOT BUT I INCLUDED THE EXCERPTHow does the word choice/ diction affect the tone of the overall text?Use specific and accurate textual evidence to support your answerExcerpt from Common Sense by Thomas PaineIn order to gain a clear and just idea of the design and end of government, let us suppose a small number of persons settled in some sequestered part of the earth, unconnected with the rest; they will then represent the first peopling of any country, or of the world. In this state of natural liberty, society will be their first thought. A thousand motives will excite them thereto; the strength of one man is so unequal to his wants, and his mind so unfitted for perpetual solitude, that he is soon obliged to seek assistance and relief of another, who in his turn requires the same. Four or five united would be able to raise a tolerable dwelling in the midst of a wilderness, but one man might labour out the common period of life without accomplishing any thing; when he had felled his timber he could not remove it, nor erect it after it was removed; hunger in the mean time would urge him to quit his work, and every different want would call him a different way. Disease, nay even misfortune, would be death; for, though neither might be mortal, yet either would disable him from living, and reduce him to a state in which he might rather be said to perish than to die.Thus necessity, like a gravitating power, would soon form our newly arrived emigrants into society, the reciprocal blessings of which would supersede, and render the obligations of law and government unnecessary while they remained perfectly just to each other; but as nothing but Heaven is impregnable to vice, it will unavoidably happen that in proportion as they surmount the first difficulties of emigration, which bound them together in a common cause, they will begin to relax in their duty and attachment to each other: and this remissness will point out the necessity of establishing some form of government to supply the defect of moral virtue.Some convenient tree will afford them a State House, under the branches of which the whole Colony may assemble to deliberate on public matters. It is more than probable that their first laws will have the title only of Regulations and be enforced by no other penalty than public disesteem. In this first parliament every man by natural right will have a seat.But as the Colony encreases, the public concerns will encrease likewise, and the distance at which the members may be separated, will render it too inconvenient for all of them to meet on every occasion as at first, when their number was small, their habitations near, and the public concerns few and trifling. This will point out the convenience of their consenting to leave the legislative part to be managed by a select number chosen from the whole body, who are supposed to have the same concerns at stake which those have who appointed them, and who will act in the same manner as the whole body would act were they present. If the colony continue encreasing, it will become necessary to augment the number of representatives, and that the interest of every part of the colony may be attended to, it will be found best to divide the whole into convenient parts, each part sending its proper number: and that the ELECTED might never form to themselves an interest separate from the ELECTORS, prudence will point out the propriety of having elections often: because as the ELECTED might by that means return and mix again with the general body of the ELECTORS in a few months, their fidelity to the public will be secured by the prudent reflection of not making a rod for themselves. And as this frequent interchange will establish a common interest with every part of the community, they will mutually and naturally support each other, and on this, (not on the unmeaning name of king,) depends the STRENGTH OF GOVERNMENT, AND THE HAPPINESS OF THE GOVERNED. is 3 1/2 greater than 1 1/15 I am having trouble!!!!
