Answers

Answer:

NG ( first and last letter of NBG)  = WS ( first and last letter of WTS).

BG = TS

G = S

N =W or NG = WS; BG = TS; G = S; N = W.

Step-by-step explanation:

We use the congruence statement to answer these questions.  From the way the congruence statement is written, we can see that N = W (they are in the same relative position in the congruence statement).  We also see that G and S are in the same relative position, so G = S.

Since N = W and G = S, this means that NG = WS.

From the congruence statement we can also see that B = T (they are in the same relative position).  Since G = S, this means that BG = TS.

Answers

The answer is a negative correlation. We can observe that as the x-coordinates (inputs) increase, the y-coordinates (outputs) decrease. We can see that this line would have a negative slope, and thus a negative correlation between the points.
Answers:

B.

Examples:

Data sets are often depicted as scatter plot graphs. This is because the purpose of these scatter plots is to check for a linear correlation between the two variables. The two variables are usually denoted as independent and dependent variables. independent variable: x, horizontal axis.

What's Now?

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).

Find the value or expression for 0.
1. sin(55) = cos( )
2.sin( )=cos(28)
3. cos(y) = sin( - )

Answers

1.

sin55 = cos35 = 0.8192

sin(55) = cos( )

Since sin and cos are complementary,

sinθ = cos(90 - θ)

Since θ = 55

sin55 = cos(90 - 55)

sin55 = cos35

So, sin55 = cos35 = 0.8192

2.

sin62 = cos28 = 0.8829

sin() = cos(28 )

Since sin and cos are complementary,

sin(90 - θ) = cosθ

Since θ = 28

sin(90 - 28) = cos28

sin62 = cos28

So, sin62 = cos28 = 0.8829

3.

cos0 = sin90 = 1

cos(y) = sin(-)

Since sin and cos are complementary,

cosy = sin(90 - y)

Since y = 0

cos0 = sin(90 - 0)

cos0 = sin90 = 1

So, cos0 = sin90 = 1

Robert is comparing prices of boxes of napkins. He sees that 2 boxes of Softeez
napkins are $1. Which of the following has a lower unit price than the Softeez
napkins?
o 12 boxes of napkins for $5.88
o 4 boxes of napkins for $2.04
o 6 boxes of napkins for $3.18
o 8 boxes of napkins for $4.16

Answers

Answer:

12 boxes of napkins for $5.88

Step-by-step explanation:

The softeez napkins are $0.50 each. Each pair of "cheaper" napkins should be at least one cent less than a dollar to be cheaper than the softeez napkins.

Dividing each price by the number of boxes of napkins, we get the price per box - 0.49, 0.51, 0.53, and 0.52 (in that order, going down).

The only ones cheaper than the napkins that are two boxes for a dollar are the first ones, which he can buy two boxes of for $0.98.

A sightseeing company charges $16.75 for a scooter rental, plus an additional $5.50 per hour that the scooter is rented. Partial hour
rentals are allowed. The total charge for a certain rental is $30.50.
How long was the scooter rented?
Enter your answer in the box.

Answers

Answer:

2.5 hours

Step-by-step explanation:

The cost of the rental - the scooter rental = 30.50 - 16.75, which equals 13.75.

Divide the additional per hour by that number.

13.75 / 5.5 = 2.5

Therefore, the scooter was rented for 2.5 hours.

Answer:

2.5

Step-by-step explanation:

13.75 / 5.5 = 2.5

125x^3-27 factor polynomials

Answers

Answer:

The answer is (5x - 3) (25x² + 15x + 9)

Step-by-step explanation:

125x³ - 27

5 × 5 × 5 × x × x × x - 3 × 3 × 3

Rewrite 125x³ as (5x)³.

(5x)³ - 27

Rewrite 27 as (3)³.

(5x)³ - (3)³

Here, Both terms are perfect cubes, factor using the difference of cube formula,

a³ - b³ = (a - b) (a² + ab + b²)

where,

a = 5x

b = 3

Now,

(5x - 3) [(5x)² + (5x)(3) + (3)²]

Now, Simplify

(5x - 3) (25x² + 15x + 9)

Thus, The answer is (5x - 3) (25x² + 15x + 9)
