Write an equation of each line in standard form.the line parallel to y=-3 x+4 through (0,-1)

The value of the expression for x² + yz when x = 7, y = 5, and z = 3 is 64.

It should be noted that from the information, we are to evaluate x² + yz for x = 7, y = 5, and z = 3.

This will be illustrated as:

= x² + yz

= 7² + (5 × 3)

= 49 + 15

= 64

Therefore, the value of the expression for x² + yz when x = 7, y = 5, and z = 3 is 64.

The values of a9 and a10 are 52 and 58 respectively.

An ordered group of integers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6. An arithmetic progression is another name for an arithmetic sequence.

For the arithmetic sequence,

4,10,16,22, . . . .

a = 4

d = 6

an = a + (n - 1)d

a9 = 4 + (8)6

a9 = 4 + 48

a9 = 52

a10 = a + 9d

a10 = 4 + 9(6)

a10 = 4 + 54

A circle is a curve sketched out by a point moving in a plane. The length of the side AD is 30.6 units.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.

The Diagram for the given details is shown below.

The length of the different sides of the triangle can be written as,

AJ = JC = Radius of circle J = 10 units

BK = KD = Radius of circle K = 8 units

BC = 5.4 units

JB = JC - BC

    = Radius of circle J - BC

    = 10 units - 5.4 units

    = 4.6 units

KC = KB - BC

    = Radius of circle K - BC

    = 8 units - 5.4 units

    = 2.6 units

Now, the length of AD can be written as,

AD = AJ + JB + BC + CK + KD

= 10 units + 4.6 units + 5.4 units + 2.6 units + 8 units

= 30.6 units

Hence, the length of the side AD is 30.6 units.

Answer:

a₂ = 101.5

Step-by-step explanation:

the nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

given a₁ = 104 and a₃ = 99 , then

104 + 2d = 99 ( subtract 104 from both sides )

2d = - 5 ( divide both sides by 2 )

d = - 2.5

then

a₂ = 104 - 2.5 = 101.5

The real interest rate is 1 percent.

The inflation rate is 3 percent.

Inflation rate is a rate that estimate the rise on prices of goods and services. The interest rate is a gain rate per unit time associated to invested capital. There are two kinds of interest rates: (i) Nominal interest rate - Inflation is neglected, (ii) Real interest rate - Inflation is not neglected.

Please notice that the difference between nominal interest rate (i) and the real interest rate (i') is the inflation rate (i''). That is:

i'' = i - i'

Now we proceed to find each missing variable:

(i = 4, i'' = 3)

i' = i - i''

i' = 4 - 3

i' = 1

The real interest rate is 1 percent.

(i' = 3, i = 6)

i'' = i - i'

i'' = 6 - 3

i'' = 3

The inflation rate is 3 percent.

a) 1.515  is the distance in Angstrom between the two hydrogen atom.

b) 0.01515 mm is the value in millimetres of 1.515

The angstrom is a metric length unit equal to 1010 m; that is, one ten-billionth (US) of a metre, one hundred-millionth of a centimetre, 0.1 nanometre, or 100 picometres. Its symbol is  is a letter from the Swedish alphabet. The unit is named after Swedish physicist Anders Jonas Ångström.

As Both H atom is equidistance from O atom The triangles shown here is isosceles triangle, where two sides are equal

So, H0 = 0H = 0.958 Angstrom

And therefor Both angle of H = 37.75°

Now using the Law of Cosines for SAS triangles

c² = a² + b² - 2ab cos(c)

Here c is the distance of H and H atoms

c² = 0.958² + 0.958² - 2(0.958)(0.958) cos(104.5°)

c² = 1.835528 + 0.45958

c²  =2.295108

c = √2.295108

c = 1.514961

Thus, 1.514961  is the distance in Angstrom between the two hydrogen atom.

Point K is located at (-6, -3) on the coordinate plane. Point K' is produced by reflecting point K over the y-axis. The ordered pair of the described location is K'(6,-3).

Given that,

Point K is located at (-6,-3) on the coordinate plane.

The sign of the x-coordinate is altered by reflection across the y-axis:

When a point is reflected across the x-axis, the x-coordinate stays constant, but the y-coordinate is thought to be the additive inverse. The x-axis shows a reflection of the point (x, y) as (x, -y).

When a point is reflected across the y-axis, the y-coordinate remains constant, but the x-coordinate is believed to be the additive inverse. The y-axis shows a reflection of the point (x, y) as (-x, y).

The summation or sigma notation is used to express long summation into a single formula.

The series, given in a summation notation, is:

The formula inside the sum notation represent the nth term, a(n).

Let evaluate the terms for some n

a(2) = (-2)²⁻¹ = (-2)¹ = -2

a(3) =  (-2)³⁻¹ = (-2)² = 4

a(4) =  (-2)⁴⁻¹ = (-2)³ = -8

This form a new geometric series, with the first term, let say f(1) = -2 and common ratio = -2.

The number of terms in this new geometric series is 5.

Use the sum formula for a geometric series,

S(n) = a(1) . (rⁿ - 1)/(r - 1)

Substitute n = 5, a(1) = -2, and r = -2 into the formula:

Time of loan in years = 3.167 = 3.2 years rounded to 1 decimal

Step-by-step explanation:

The question is only asking for the number of years, not the accrued principal. This should be straightforward:

38 months = 38/12 years = 3.166.... = 3.2 years rounded to 1 decimal point

Here are the accrued amount and interest computations in case you need them:

14% interest annually = 0.14 decimal

Since it is compounded daily we have to divide by 365, the number of days in a year

Also the time period will now be 365 x number of years = 365 x 3.2 = 1168 since it is being compounded daily

At 14% compounded daily, the accrued amount will be

[tex]A = \left( 1 + \dfrac{0.14}{365}\right)^{(365)( 3.2)} = \$4,695.13\\\\\mathrm{Interest } = \$4,695.13 - \$3000 = \$1,695.13[/tex]

The first paycheck payment to the independent contractor is $4,615.38

Dr. salaries and wages expense $4,615.38

Cr. salaries and wages payable                     $4,615.38

What is the amount of first  bi-weekly pay to the contractors?

On the basis that there are 52 weeks in a year, hence, there would be 26 bi-weeks in a year, in order to determine the amount of first paycheck payment to the independent contractor, we simply divide the annual cost of contract by 26 bi-weeks in a year.

first paycheck payment =annual contract fees/26 bi-weeks

first paycheck payment =$120,000/26

first paycheck payment =$4,615.38

The paycheck refers to first 2 weeks which ends on on  12th January, whereas the actual payment would occur a week later on 19th of January, as a result, the amount is owed until 19th January, which means that salaries and wages expense would be debited and salaries and wages payable would be credited until actual payment is made on the 19th of January.

Step-by-step explanation:

The equation of the line in point-slope form, with slope equal to -3/5 and passing through the point located at (-4 , 0), is (y - 0) = -3/5(x + 4).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Using the point slope form, plug in the values to set up the equation.

(y - y1) = m(x - x1)

where m = -3/5 and (x1 , y1) = (-4 , 0)

(y - 0) = -3/5(x - -4)

(y - 0) = -3/5(x + 4)

In slope-intercept form, the equation of the line is:

(y - 0) = -3/5(x + 4)

y = -3/5 x - 12/5

In standard form, the equation of the line is:

y = -3/5 x - 12/5

3/5 x + y = -12/5

Multiplying both sides by 5,

3x + 5y = -12
