Jake put the money in the savings account for about 17.5 years.

Simply explained, a savings account is a place where you can deposit funds and earn interest.

Most people won't pay any tax on their savings interest because it is paid tax-free. Only people with extremely big sums of savings would need to be concerned about this, which is less than 5% of us as basic-rate taxpayers can earn £1,000/year tax-free and higher-rate taxpayers £500.

The interest calculated in a savings account is compound interest:

So let us now calculate the savings rate of interest at 3.5% for the whole time

We know that

[tex]A=P(1+r)^n[/tex]

Where A is the amount , P is the principal , r is the rate and n is the time.

Substituting the values we calculate the value of x.

6400 = 3500 ( 1+0.035 )ⁿ

or, n = 17.54..

So the time required will be about 17.5 years in the savings account.

If the cost of fabric be at $10.99 a yard, then a 5% yards would cost $0.55

The given parameters are

Cost of fabric = $10.99 per yard

This means that the unit rate of a yard of fabric is $10.99

So, the cost of a 5% yard cost of fabric would be

Cost = 5% * Cost of fabric

The above equation becomes

Cost = 5% * 10.99

Evaluate the product

Cost = $0.55

Hence, if the cost of fabric be at $10.99 a yard, then a 5% yards would cost $0.55

The true statement concerning the vertex and the axis of symmetry of g(x) = 5x^2 − 10x is that both values are equal

Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

The equation of the function is given as

g(x) = 5x^2 - 10x

Differentiate the above equation

So, we have

g'(x) = 10x - 10

Set to 0

So, we have

10xx - 10 = 0

Divide through by 10

So, we have

x - 1 = 0

Solve

x = 1

The above is the x coordinate of the vertex and the axis of symmetry

Hence, the true statement concerning the vertex and the axis of symmetry of g(x) = 5x^2 − 10x is that both values are equal

Subtract $30 from both sides

$.40x = $28.80

Divide both sides by $.40

Answer:

f(2) = -9, and f(-2) = 19

Step-by-step explanation:

Just plug it in.

If  [tex]f(x) =2x^{2} -3x+5[/tex], and you have f(2), and f(- 2), you can do, [tex]f(2) = -2(2^{2} )-3(2)+5[/tex], and [tex]f(-2)=-2(-2^{2} )-3(-2)+5[/tex].

Once you do all the math, you get f(2) = -9, and f(-2) = 19.

The correct expression is  6^(-11).

Exponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner.

Given:

6^(-5) / (6^2)^3

Now, using laws of exponents

(a^m)^n = a^(mn)

6^(-5) / (6^6)

again using laws of exponents

a^m/ a^n= a^(m-n)

So, 6^(-5-6)

=6^(-11)

4(x-3) = 0.5x +2

Multiply both sides by 10

40(x-3) + 5x + 20

Simplify (multiply 40 by x-3)

40x - 120 = 5x + 20

Add 120 to both sides

40x = 5x + 140

Subtract 5x from both sides

35x = 140

Divide 35 on both sides

The square of the imaginary number i is -1.

If you multiply a real number by the imaginary unit I which has the characteristic i2 = -1, you get an imaginary number. The imaginary number bi is squared as -b2. Zero is, by definition, both real and fictional.

A number that results from multiplying a non-zero real number by the iota I is an imaginary number. I in this case Equals (-1) or i2 = -1. Finding the square root of negative integers is made easier by using these values. -4i, 6i, I etc. are some instances of imaginary numbers.

i is an imaginary number where,  [tex]i=\sqrt{-1}[/tex]

The most cost-effective choice for buying the item is buying it at a 10 percent discount without sales tax.

A percent discount on a product means that the price of the product is reduced by that percentage.

The full question is that, You want to buy an item that costs $100. Which of these is the most cost-effective choice for buying the item?.

a. using a paid membership card to buy it at a 10 percent discount.

b. buying it online at a 10 percent discount with a $5 shipping charge.

c. buying it at a 10 percent discount without sales tax.

we will calculate the final price in each case to analyze the most cost-effective choice,

In in first case, when using a paid membership card to buy it at a 10 percent discount. we get,

10% of $100 = 10/100×100 = $10

cost = $100 - $10 = $90

On top of this $90 there is the charges of the membership card, therefore the price increases. ( price in first case)

In second case, when buying it online at a 10 percent discount with a $5 shipping charge.

100%-10% = 90%

90% of 100 = $90

Cost: $90 + $5 = $95 ( price in second case)

In third case, when buying it at a 10 percent discount without sales tax.

100% - 10% = 90%

90/100 × 100 = $90. ( price in third case which is minimum as compared to rest of the cases)

Therefore, buying the item at a 10 percent discount without sales tax is the most cost effective method since there is no other cost involved.
