In general an annual rate of $r$ compounded monthly will multiply the amount by a factor of $1+\frac{r}{12}$ each month.

Each month of 4.3% is a factor of $1+\frac{.043}{12}$ . That goes for five months, so is multiplied by itself five times, so gets a fifth power.

Each month of 13.7% is a factor of $1+\frac{.137}{12}$ . He pays this for 12-5=7 months, so it gets an exponent of seven.

We started the year owing $2600 of principal, so after the year we owe

$2600(1+\frac{.043}{12})^5(1+\frac{.137}{12})^7$ .

Choice A.

Answer:

To expand a polynomial, multiply its factors (often by using the distributive property) or perform the indicated operations. Then combine all like terms. Example. Expand the following expression. 3x(4 - x) + (2x - 5)2.

how to do it, if you dont know use the steps.

Using the data: 2, 2, 3, 3, 3, 4, 5, 6, 6, 19 What is Q1 and Q3

Anettt [7]

Answer:

$Q_1=2$

$Q_3=6$

Step-by-step explanation:

Notice that we already have the data sorted from least to greatest.

Now to find Q1 and Q3 we can use the following formulas

For a set of data ordered from least to greatest of the form $X_1, X_2, ..., X_n$

Where n is the total number of data

$Q_1=X_{\frac{1}{4}(n+1)}$

In this case $n=10$

So:

$Q_1=X_{\frac{1}{4}(10+1)}$

$Q_1=X_{2.75}$

Round the nearest whole and get:

$Q_1=X_{3}$

$Q_1=3$

For Q3 we have:

$Q_3=X_{\frac{3}{4}(n+1)}$

$Q_3=X_{\frac{3}{4}(10+1)}$

$Q_3=X_{8.25}$

Round the nearest whole and get:

$Q_3=X_{8}$

$Q_3=6$

1 less than 1/4 Question: Peggy is pp years old. Maggie is 11 year less than \frac{1}{4} 4 1 of Peggy's age. What is Mag

Nonamiya [84]

Answer:

$M=\dfrac{(p-44)}{4}\ \text{years}$

Step-by-step explanation:

Given that,

Peggy is p years old.

Maggie is 11 year less than 1/4 of Peggy's age.

It means,

Maggie's age,

$M=\dfrac{1}{4}\times p-11\\\\M=\dfrac{p}{4}-11\\\\M=\dfrac{(p-44)}{4}$

So, Maggie's age is $\dfrac{(p-44)}{4}$ years.

The value of y varies directly with x. When y = 8.4, x = 3.5. What is the value of x when y is 12?

iris [78.8K]

Answer:

the value of x will be 7.1 when y = 12

Step-by-step explanation:

first you would find the difference between the y value 8.4 and see how far it is from 12. you should get 3.6 after that, add 3.6 and the x value and that'll give you your x for when y = 12.

Choose all the rigid mapping rules that hold congruence.

Ulleksa [173]

Rigid mapping is used to illustrate rigid transformation.

The rigid mapping rules are:

(a) (x, y)->(y,x)
(c) (x, y)->(-y, x)
(d) (x, y)-> (-y +4, X-6)
(e) (x, y)->(x + 4, y-5)
(f) (x, y)->(x, x+y)

All transformations are rigid except dilation.

This is so, because dilation changes the size of the function that is being transformed, while others do not.

Dilations are represented by scale factors (product or division)

From the list of given options

(b) (x, y)->(3x, y) and (c) (x,y)-> (3) are non-rigid mapping because they represent dilations.

Hence, the rigid mapping rules are:

(a) (x, y)->(y,x)
(c) (x, y)->(-y, x)
(d) (x, y)-> (-y +4, X-6)
(e) (x, y)->(x + 4, y-5)
(f) (x, y)->(x, x+y)
