Margot preformed a refection. A reflection is a rigid transformation.

A rigid transformation does not change the size nor the shape of the figure. Rigid transformations only change the position of the shape.

The parallel lines stay 4 centimetres apart after the transformation.

Answer:

$3050.48

Step-by-step explanation:

If 4% is compounded quarterly, that means it's 1% every quarter. since we have 5 years, that's 1.01^20, which is approx. 1.2202. We multiply this by the orignal $2500, so our investment at the end of 5 years is $3050.48 (rounded to nearest cent)

The amount of money that Tia's investment would be worth at the end of 5 years is equal to $3050.5.

Given the following data:

To determine how much is the investment worth at the end of 5 years:

Mathematically, compound interest is given by the formula:

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]

Where;

Substituting the given parameters into the formula, we have;

[tex]A = 2500(1 + \frac{0.04}{4})^{4\times 5}\\\\A = 2500(1 +0.01)^{20}\\\\A = 2500(1.01)^{20}\\\\A = 2500(1.2202)[/tex]

Future value, A = $3050.5

Answer:

[tex]P(System) = 0.73304[/tex]

Step-by-step explanation:

Given

Reliability of:

A = 0.98

B = 0.85

C = 0.88

Required

Determine the overall reliability

The overall system reliability is calculated by multiplying the individual reliability of each subsystems;

i.e.

[tex]P(System) = P(A) * P(B) * P(C)[/tex]

[tex]P(System) = 0.98 * 0.85 * 0.88[/tex]

[tex]P(System) = 0.73304[/tex]

Hence, the overall reliability is  0.73304

Step-by-step explanation:

6(x - 2)² + 7 = 223

PEMDAS

expand (x - 2)² first using FOIL

(x - 2)(x - 2)

x² - 2x - 2x + 4

x² - 4x + 4

rewrite equation

6(x² - 4x + 4) + 7 = 223

distribute the 6 through the parentheses

6x² - 24x + 24

rewrite equation

6x² - 24x + 24 + 7 = 223

combine like terms

6x² - 24x + 31 = 223

subtract both sides by 223

6x² - 24x - 192 = 0

divide both sides by 6

x² - 4x - 32 = 0

factor with factoring X

x² - 8x + 4x - 32 = 0

factor by grouping

(x² - 8x) + (4x - 32) = 0

x(x - 8) +4 (x - 8) = 0

(x - 8)(x + 4) = 0

x = 8 or -4

Answer:

Step-by-step explanation:

Given Tyler test grades to be 77%, 62% 85% and 80%, to find its average in the class, we will find the mean of his grades.

Mean is the ratio of the sum of the grades to the total number of grades given.

[tex]mean (\overline x) = \frac{\sum Xi}{N}[/tex]

Xi are the individual grades

N is the total number of grades = 4

[tex]\overline x = \dfrac{77+62+85+80}{4} \\\overline x = \frac{304}{4}\\ \overline x = 76 % \\[/tex]

Hence his average in the class is 76%

Answer: (8)($4)

Answer with an explanation:

What we need to know: Any number 5 or higher is automatically rounded up, any number 4 or lower is automatically round down. Also if the number is after the decimal you can say 5 or higher with a zero because it doesnt do anything to the number, so you could say .50 or higher or .40 or lower and if it has three decimal places just add another zero so it would be .500 higher or .400 lower.

So, 7.9 is rounded up to 8.0 because 9 is 5 or higher.

$3.89 is rounded up to $4.00 because .89 is higher than .50.

Now just take off the zeros from 8.0 and $4.00 to get (8)($4)

Answer:

Susan has a total of 660 nails

Step-by-step explanation:

John box contains 65 small nails, 40 medium nails, and 45 large nails.

The proportion of John nails is

65/5:40/5:45/5

13:8:9

Total = 30

If Susan has 176 medium nails and same proportion to John's nails

8/30(x) = 176

Where x is the total number of nails for Susan box

X= (176*30)/8

X= 22*30

X= 660 nails

Susan has a total of 660 nails

Answer:

7x^2 - 3y + 9

Step-by-step explanation:

   2y - y + 7 - 1 + 3 + 7x^2 - 4y          [Combine like terms]

= (2y - y - 4y) + (7- 1 + 3) + 7x^2

= -3y + 9 + 7x^2                 [Order the terms from most exponents to least]

= 7x^2 - 3y + 9
