If $10,000 is invested at 6% annual interest compounded yearly, what is the account balance after 4 years, assuming no additiona

Aleks04 [339]

Answer:

a = $12,600

Step-by-step explanation:

Formula for Compound interest :

$a = p{(1 + \frac{r}{100} )}^{n}$

a = Amount

p = Initial Principal

r = Interest rate per annum

n = number of years

$a \: = 10000(1 + 0.06)^{4}$

a = 10,000 * (1.26)

a = $12,600

As notas de dois alunos X e Y estão representadas no quadro abaixo. Por meio da variância, qual deles apresentou ser o mais regu

Reil [10]

Answer:

Aluno X

Step-by-step explanation:

A nota média para os alunos X e Y são, respectivamente:

$X_m=\frac{5+3+5+7}{4}=5 \\Y_m=\frac{4+9+4+3}{4}=5$

A variância é definida pela seguinte expressão:

$V=\frac{\sum(X_i-X_m)^2}{n-1}$

Onde n é o numero de termos, neste caso, n = 4.

As variâncias para cada aluno são:

$V_x=\frac{(5-5)^2+(3-5)^2+(5-5)^2+(7-5)^2}{4-1} \\V_x= 2.7\\V_y=\frac{(4-5)^2+(9-5)^2+(4-5)^2+(3-5)^2}{4-1} \\V_y= 7.3$

O aluno X apresentou uma variância menor do que o aluno Y em suas notas e, portanto, apresentou ser o mais regular.

Need help with this

Stells [14]

Answer:

38 = D

Step-by-step explanation:

The 3 angles of a triangle equal 180 degrees

<B + <C + <D = 360

7x+ 12 + 2x+13 + 2x+ 12 =180

Combine terms

11x+37 = 180

Subtract 37 from each side

11x+37-37 = 180-37

11x =143

Divide by 11

11x/11 = 143/11

x =13

We want to find angle D

2x+12 = D

2(13) + 12 = D

26+12 = D

38 = D

What does an isometric transformation do?

BaLLatris [955]

Answer:

Option: B is correct.

( Preserves the shape and size of the figure )

Step-by-step explanation:

An ISOMETRIC TRANSFORMATION (RIGID MOTION) is a transformation that preserves the distances and/or angles between the pre-image and image.
The isometric transformations are reflection, rotation and translation and combinations of them such as the glide, which is the combination of a translation and a reflection.

Hence, option B is correct.

Preserves the shape and size of the figure.
