Step-by-step explanation:

10^3 in scientific notation means to move the decimal 3 places to the right.

The complementary solution is Ус = C₁е¯ + C₂е¯ -6x

Consider the differential equation

=y" + 7y' + 6y = 30...(1)

Rewrite the equation,(D² + 7D + 6)y = 30 where

d /D = dx

Auxiliary equation is,

f(m) = 0

3 m³ +7m+6=0

m² + 6m+m+6=0

m(m+6) +1(m+6) = 0

(m +6)(m + 1) = 0

m = −1, −6 -6

Hence,

The complementary solution is Ус = C₁е¯ + C₂е¯ -6x

What is the overtime pay rule?

The civil overtime vittles are contained in the Fair Labor norms Act,  Unless pure, workers covered by the Act must admit overtime pay for hours worked over 40 in a workweek at a rate not lower than time, and That's an illustration of total pay for a hand who worked 42 hours in a workweek Regular pay rate x 40 hours = Regular pay, plus. Regular pay rate x1.5 x 2 hours = Overtime pay, equals.

Usual earning Earning = $8.5 for 30 hours for a week

Overtime = 47 hours-30 =17 hours

Overtime rate = $8.5 + $8.5/2 = $ 12.75 for hour for a week

Gross pay= ($8.5*30)+($12.75*17)

Step-by-step explanation:

Women make up 64% of the sample and are typically the household's main investment.

There is a correlation between American women and being the main provider in their home.

Descriptive statistics, also known as brief informative coefficients, are used to summarize a specific data collection, which may be a sample of a population or a representation of the entire population. Descriptive statistics include measures of variability and central tendency (spread). Measures of central tendency include the mean, median, and mode, whereas measures of variability include the standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.

For instance, the sum of the following data set is 20: (2, 3, 4, 5, 6). A 4 (20/5) is the mean. A data set's mode is the number that appears most frequently, while its median is the value that is in the middle of the range of values. It is the value that separates a data set's higher values from lower values. There are many less common ways to use descriptive statistics, but they are nevertheless essential.

Astronauts brought back 500 lbs rock samples from the moon they brought back 227 kilograms of sample. The correct option is D.

Who, in brief, is an astronaut?

As the astronaut brought 550 lbs sample,

2.20lbs = 1 kg.

1 lbs = 1/2.20

1 lbs = 0.45

so, 500 lbs nearly implies 227kgs.

Answer:64y^2 −80y+25

Step-by-step explanation:

DE is parallel to ST as ∠ EAT = ∠ AED which are alternate interior angles.

∠TAC = ∠ABC  (The angle between the chord and the tangent is equal to the angle in the alternate segment)

Since, EDCB is a cyclic quadrilateral,

     ∠CBD + ∠CED = 180  ----- I

-      ∠CED + ∠AED = 180   -----II

----------------------------------------------------

   ∠ CBD =  ∠AED

Also, ∠ CBD = ∠ EAT( A is tangent to the circle)

So, ∠ EAT = ∠ AED ( Alternate interior angle)

So, DE || ST

Therefore, DE is parallel to ST as ∠ EAT = ∠ AED which are alternate interior angles.

The height of the boat floating above the seafloor at high tide is 17.5 feet.

In this question, we have been given a boat which is anchored in the water.

At low tide, the boat is floating 20 feet above the seafloor and is a horizontal distance of 40 feet away from its anchor.

And at high tide, the boat is a horizontal distance of 35 feet away from its anchor.

We need to find the distance the boat floating above the seafloor at high tide.

Consider the following diagram.

Let the boat floating m feet above the seafloor when the boat is a horizontal distance of 35 feet away from its anchor.

Since both the triangle are similar triangles, the corresponding sides must be in proportion.

⇒ 20/40 = m/35

We need to find the value of m.

⇒ 20 × 35 = m × 40

⇒ m = 35 / 2

⇒ m = 17.5 feet

Therefore, the height of the boat floating above the seafloor at high tide is 17.5 feet.

The transformed equation is:

F(x) = G(x + 2) = (x + 2)^2

So we can se that the correct option is D.

We know that the graph of F(x) has the same shape of G(x) = x^2, but shifted to the left 2 units.

Remember that for a random function f(x), a shift of 2 units to the left is written as:

h(x) = f(x + 2).

Then, in this case, we can write:

F(x) = G(x + 2)

Replacing G(x), we can get the transformed equation:

F(x) = G(x + 2) = (x + 2)^2

So we can se that the correct option is D.
