What is compound interest?

Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.

The formula for the final amount with the compound interest formula can be given as,

[tex]A=P\times\left(1+\dfrac{r}{100n}\right)^{nt}\\[/tex]

Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.

$13,000 is deposited into a savings account with an annual interest rate of 3% compounded continuously.

The amount in account after 5 years can be calculated with the above formula as,

[tex]A=13000\times\left(1+\dfrac{3}{12\times100}\right)^{12\times5}\\A=15101.02[/tex]

dollars) does she have if she has z dimes and y quarters?
Total value, 12 dimes and 5 quarters (dollars):
Total value, x dimes and y quarters (dollars):

Answers

Answer:

1) $2.45

2) $(0.25y + 0.1z)

Step-by-step explanation:

dimes are 0.10 in value, quarters are 0.25

1) How much money in dollars does she have if she has 12 dimes and 5 quarters? 12(0.1) + 5(0.25) = 1.2 + 1.25 = $2.45

2) How much money in dollars does she have if she has z dimes and y quarters?

z(0.10) + y(0.25)= 0.25y + 0.1z

I rearranged it because we put variables in alphabetical order.

LMK if you have questions.

a) The total value of 12 dimes and 5 quarters is  $ 2.45

b) The total value of x dimes and y quarters is  0.10x + 0.25y

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the value of 1 dime = 10 cents

                                      = $ 0.10

Let the value of 1 quarter = 25 cents

                                          = $ 0.25

Now the equation will be

a)

The value of 12 dimes = 12 x value of 1 dime

                                     = 12 x 0.1

                                     = $ 1.2

The value of 5 quarters = 5 x value of 1 quarter

                                       = 5 x 0.25

                                       = $ 1.25

So , the value of 12 dimes and 5 quarters is =
value of 12 dimes + value of 5 quarters

The value of 12 dimes and 5 quarters is = $ 1.2 + $ 1.25

                                                                   = $ 2.45

b)

The equation will be

The value of x dimes = 0.10x

The value of y quarters = 0.25y

So , the value of x dimes and y quarters is =
value of x dimes + value of y quarters

The value of x dimes and y quarters is = 0.10x + 0.25y

Hence , a) The total value of 12 dimes and 5 quarters is $ 2.45

b) The total value of x dimes and y quarters is 0.10x + 0.25y

Find the coordinates for B, C, and D. Note line 1 must be perpendicular to line 2.

Answers

Answer:

B = (-b, a)

C = (a, 0)

D = (-b, 0)

Step-by-step explanation:

Line 1(L₁) passes through the point O(0, 0) and A(a, b). Hence the equation of L₁ is:

[tex]y-y_1=\frac{y_2-y_}{x_2-x_1}(x-x_1) \\\\y-0=\frac{b-0}{a-0} (x-0)\\\\ay -bx=0[/tex]

Point C has the same x coordinate as point A. Since point C is on the origin line (y = 0 line), its y coordinate is 0.

The coordinate of C = (a, 0)

L₁ has a slope of b/a. Since L₂ is perpendicular to L₁, the product of their slope is -1. Hence slope of L₂ = -a/b

L₂ has a slope of -a/b and pass through  the origin. The equation of L₂ is:

[tex]y-y_1=m(x-x_1)\\\\y-0=\frac{-a}{b}(x-0)\\\\y= \frac{-a}{b}x[/tex]

But OD = AC

AC = b

Hence OD = AC = b

The y coordinate of D is 0. Let its x coordinate be -x. Hence D = (-x, 0)

[tex]OD=\sqrt{(-x-0)^2+(0-0)^2} \\\\OD=x\\\\OD=x=b\\\\x=b;-x=-b[/tex]

The coordinate of D is (-b, 0)

B has the same x coordinate as D. The y coordinate of B is gotten by using L₂ equation and substituting x = -b

y = (-a/b)(-b)

y = a

Coordinate of B = (-b, a)

The lid will have a base area of 55 1/4 square inches. The long sides of the lid will each have an area of 17 square inches. The short sides of the lid will each have an area of 13 square inches. The total surface area of the lid will be 115 1/4 square inches.

So, for the base, you have w = 6.5 and l = 8.5. Area = 6.5 * 8.5 = 55.25 = 55 1/4.

For the long sides, you have l = 8.5 and h = 2. Area = 8.5 * 2 = 17

For the short sides, you have w = 6.5 and h = 2. Area = 6.5 * 2 = 13

For the total surface area, you have one base which is 55.25, you have two long sides which are 2 * 17 = 34, and you have two short sides which are 2 * 13 = 26. 55.25 + 34 + 26 = 115.25 = 115 1/4.
