The finance charge is. s= 80/3 m.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

The price of a stove is s dollars.

Pedro makes 10% down payment for a two year installment purchase.

The monthly payment is m dollars.

Also, 2 years= 24 month

Then, the finance charge is

s x(1- 10%) / 24 = m

m= s ( 1- 0.10) / 24

24m = 0.9s

s= 24m/ 0.9

s= 80/3 m

The graph of an absolue value function is V shaped, symmetric about y-axis or any line parallel to y-axis.

We know that an absolute value of any number describes the distance from zero of that a number is on the number line, without considering its sign (negative / positive number).

Consider an absolute value function f(x)

f(x) = |x|

This means, |x| = x              .......(if x ≥ 0)

            and |x| = -x              .......(if x < 0)

We know that the graph of the absolute value function is V shaped and symmetric about the y -axis or any line parallel to y-axis.

The graph makes a right angle at the origin.

The graph of absolute value consists of two pieces: one with a negative slope and the one with a positive slope.

Also, in the graph of absolute value function a vertex is the point at which the graph of the function changes its direction.

The figure has an image of right triangle and the dimensions are solved to get

The right triangle's sides are solved using SOH CAH TOA

Sin = opposite / hypotenuse - SOH

Cos = adjacent / hypotenuse - CAH

Tan = opposite / adjacent - TOA

From the question it can be deduced that

opposite = 12 ft

adjacent = b

hypotenuse = c

Using tan, TOA the adjacent is solved

tan 30 = Opposite / Adjacent

tan 30 = b / 12 ft

b = 12 / tan 30

b = AC = 20.784 ft

The hypotenuse is calculated using cos, CAH

cos 30 = Adjacent / hypotenuse

cos 30 = 20.784 / c

c = 20.784 / cos 30

c = AB = 24 ft

What you can do in this case is the following rule of three to find the result:

1 light year ---> 5.88 * 10 ^ 12 miles

3.2 * 10 ^ 2 light year ---> x

Clearing x we have:

x = ((3.2 * 10 ^ 2) / (1)) * (5.88 * 10 ^ 12)

x = 1.88 * 10 ^ 15 miles

answer:

In scientific notation, approximately it is 1.88 * 10 ^ 15 miles

The equation of the line that passes through the points (36,-30) and (-12,34) is  y = - 4 / 3 x + 18.

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

Therefore, let's find the equation of the line  that passes through the points (36, -30) and (-12, 34).

Hence, the slope can be found as follow:

slope = y₂ - y₁ / x₂ - x₁

slope = 34 + 30 / -12 - 36

slope = 64 / -48

slope = - 8 / 6 = - 4 / 3

Therefore, let's find the y-intercept of the line using (-12, 34)

y = - 4 / 3 x + b

34 = - 4 / 3 (-12) + b

34 = 16 + b

b = 34 - 16

b = 18

Therefore, the equation is y = - 4 / 3 x + 18.

A triangle's perimeter is determined by the sum of its three sides. The perimeter of triangle is 16

Sum of the three sides determines a triangle's perimeter.Additionally, the units used to measure the lengths of a triangle's sides and perimeter are the same.If the sides of it have lengths that are measured in various units, convert them to that unit first.

The lengths of all four side edges must be added up in order to determine the rectangle's perimeter.Since there are two of each side length, it is easy to accomplish this by simply multiplying the sum of the length and width by two.

(Length + Width)2 is the perimeter calculation formula.

The perimeter is the sum of the lengths of all sides.

Using the distance formula, determine the lengths of the sides:

d  = √ ( x2 - x1 ) ² + ( y2 - y1 )²

Adrian need to invest $2041.88,  to the nearest hundred dollars for the value of the account to reach $3900 in 14 years.

Let principal amount is x

And interest is y

Then, according to question

X + y = 3900    --------------eq(1)

and formula of interest

I = (P*t*R)/ 100

Y = (x * 14 * 6.5) / 100   ----------------------eq(2)

3900 – x = (x * 14 * 6.5) / 100  from eq(1) and eq(2)

390000 – 100x = 91x

191x = 390000

X = 2041.88

So, therefore principal amount = $2041.88

and interest = $1858.12

You can earn interest on interest by using compound interest. Compound interest is interest that is earned on both the initial principal and interest that builds up over time in a savings account.

You get interest based on the amount you deposit when you add money to a savings account or other account of a similar nature. For instance, if you deposit $1,000 in an account that offers 1% yearly interest, after a year you would have received $10 in interest.

There may be a difference in the timing of when interest is paid out and compounded. For instance, interest on a savings account may be paid monthly but compounded daily. The account balance plus any interest that has accrued but has not yet been paid out are used by the bank to determine your daily interest earnings.

The point estimate from a confidence interval can be found by taking the midpoint of the interval.

The formula for the point estimate is (lower bound + upper bound) / 2. For example, the 95% confidence interval for a sample mean of 25 is (23, 27). The point estimate for this sample mean is (23 + 27) / 2 = 25. This point estimate is the best estimate of the true population mean.

In essence, the point estimate is the best guess of the population mean given the data. It is calculated by taking the midpoint of the confidence interval, which is the range of values that is believed to contain the population mean with a certain degree of confidence. The point estimate is usually the most reliable estimate and is used to make decisions in statistical analysis.

2 and 3 has a multiplicative inverse of -3 and 2, which is 2. A number that, when multiplied by the inputted number, produces the result 1 is said to be the multiplicative inverse of that number.

When a number is multiplied by another, the result is 1, this is known as the multiplicative inverse of the original number . It is the reciprocal of a number per multiplicative inverse definition. A-1 or is used to denote the multiplicative inverse of a number "a".

According to the multiplicative inverse property, a multiplies with its reciprocal, 1/a, to get 1, for any number a. It follows that 1/a is a number's multiplicative inverse. The multiplicative inverse of 5, when applied to the integer 5, is 1/5, according to this characteristic. Dividing 1 by a real number yields the multiplicative inverse of that number.

If tangent of x degrees equals four-thirds, and measures of triangle is 10. 5 units, and NM measures 2b units then the value of b is equals to seven. So, last option is correct, b = 7 here.

Right angled triangle : A triangle is defined as a regular polygon, with three sides and the sum of any two sides is always greater than the third side. Right angled triangle is one type of triangle. When the angle between a pair of sides is equal to 90 degrees it is called a right-angle triangle. See in above figure ∆LMN is a right angled triangle with m∠LMN = 90° . Also, we have m∠MLN = x° so, m∠LNM = 180° - 90° - x° = 90° - x° ( Since, sum of interior angles of triangle = 180°)

Length of side LM = 10.5

length of side, NM = 2b

tangent of x, tan x = 4/3

We have to determine the value of b. For considering angle x° as centre point then

base of triangle = LM = 10.5

As we know Tangent of any angle is equals to ratio of perpendicular/base.

so, tan x = 4/3 = LM/NM

=> 4/3 = 2b / 10.5

=> 4× 10.5 = 2b × 3

=> b = 42.0/6
