To turn $900 into $900 over the course of two and a half years at the rate of 3.5%, we can use the following formula:

Copy code

investment = (900 * (1 + 0.035)) ^ (2.5 / 1)

In this formula, investment represents the amount of money you need to invest, 900 represents the final amount you want to end up with, 0.035 represents the interest rate of 3.5%, 2.5 represents the number of years you want to invest for, and 1 represents the number of times per year that the interest is compounded.

Plugging in the values from the problem into the formula, we get:

Copy code

investment = (900 * (1 + 0.035)) ^ (2.5 / 1)

investment = ($900 * 1.035) ^ (2.5 / 1)

investment = $931.75 ^ 2.5

investment = $1434.24

Therefore, to turn $900 into $900 over the course of two and a half years at the rate of 3.5%, you will need to invest $1434.24.

The required simplified value of the given expression is 120.

Given that the expression as;

(50 + 30) + 40.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here, we have;

= (50 + 30) + 40

Now, using associative property, in parenthesis 50 + 30 become 80.

Therefore , the height of the given square pyramid is 12 cm.

The area occupied within an object's three-dimensional bounds is referred to as its volume. The object's capacity is another name for it.

Here,

To calculate a square pyramid's volume in terms of h, use the formula h = [tex]\frac{3V}{s^{2} }[/tex]

With V = 400 and s = 10 cm, a square pyramid's height is 12 cm.

The equation for calculating the volume of a square pyramid is:

=> 1/3 [tex]s^{2}[/tex]h =V

=> h = [tex]\frac{3V}{s^{2} }[/tex]

Therefore we can rewrite the formula in terms of h you need to:

=> h = [tex]\frac{3V}{s^{2} }[/tex]

You must substitute these numbers into the following formula to determine the height of a square pyramid with volume V = 400 and side lengths s = 10 cm:

=> h = 3 * 400 / [tex]10^{2}[/tex]

=> 3* 400/100

Answer:

[tex]\textsf{A)} \quad -1\dfrac{3}{20}y+4[/tex]

Step-by-step explanation:

Given expression:

[tex]\left(11-9 \dfrac{3}{5}y\right)+\left(8 \dfrac{9}{20}y-7 \right)[/tex]

Remove the parentheses:

[tex]11-9 \dfrac{3}{5}y+8 \dfrac{9}{20}y-7[/tex]

Collect like terms:

[tex]8 \dfrac{9}{20}y-9 \dfrac{3}{5}y+11-7[/tex]

Subtract the numbers 11 - 7:

[tex]8 \dfrac{9}{20}y-9 \dfrac{3}{5}y+4[/tex]

Factor out y:

[tex]\left(8 \dfrac{9}{20}-9 \dfrac{3}{5}\right)y+4[/tex]

Partition the mixed numbers into fractions and whole numbers, and then subtract them separately.

Subtract the whole numbers:

[tex]\implies 8-9=-1[/tex]

Subtract the fractions by changing both fractions into equivalent fractions so both fractions have the same denominator:

[tex]\implies \dfrac{9}{20}-\dfrac{3}{5}[/tex]

[tex]\implies \dfrac{9}{20}-\dfrac{3 \cdot 4}{5 \cdot 4}[/tex]

[tex]\implies \dfrac{9}{20}-\dfrac{12}{20}[/tex]

[tex]\implies -\dfrac{3}{20}[/tex]

Put the two answers from the whole numbers and fractions back together:

[tex]\implies -1-\dfrac{3}{20}=- \left(1+\dfrac{3}{20}\right)=-1\dfrac{3}{20}[/tex]

Therefore:

[tex]\left(8 \dfrac{9}{20}-9 \dfrac{3}{5}\right)y+4=\left(-1\dfrac{3}{20}\right)y+4=-1\dfrac{3}{20}y+4[/tex]

The required Polynomial equation is − 5x²+ 19x + 4.  

Factorization is the process of determining the factors of a given value or algebraic statement. The numbers or the algebraic expressions that are multiplied to create the original number or original expressions are known as factors.

If p(x) is polynomial, with factors (x + a) and (x - a) then p(x) will equal to product of (x + a) and (x - a) => p(x) = (x + a)(x - a)

Here we have

The factorization of a polynomial is −1(x − 4)(5x+1)

To find the Polynomial we need to multiply given factors as given below

=> −1(x − 4)(5x+1)

Yes subtracting a number is the same as adding its inverse. We have to find the additive inverse of a function.

The additive inverse of a number is the number which when we add to the number results zero.

Complex numbers are made up of both real and fictitious numbers. A + iB, where A is the real number and B is the imaginary number, is a complex number.

The additive inverse of A + iB should now be a value that, when added to a given complex number, produces the result zero. It will therefore be -(A + iB).

Suppose we have to find additive inverse of 5.

Let the additive inverse of 5 be x.

So,5+x=0

x=-5

So the additive inverse of 5 is -5.

Hence to find additive inverse of a positive number we have to just put a negative mark and for a negative number we have put positive mark in front of the number.

Answer:

  A:) T(t) = 305(230/305)^(t/10) +70

  B:) T(20) ≈ 243.4 °F

Step-by-step explanation:

You have a pie removed from a 375° oven to a room temperature of 70° that has cooled to 300° after 10 minutes. You want to know its temperature after 20 minutes.

Newton's law of cooling tells you the rate of change of an object's temperature is proportional to the difference between the object's temperature and that of its surroundings. The differential equation describing this has an exponential function as its solution. That exponential function can be written as ...

  temperature = (initial temperature difference)·(cooling factor)^(time/(cooling time)) + (final temperature)

Here, the initial temperature difference between the pie and room temperature is ...

  initial temperature difference = 375° -70° = 305°

The final temperature is the room temperature:

  final temperature = 70°

The cooling factor is the multiplier applied to the temperature difference in the time period "cooling time". Here, the pie is at 300°, a temperature difference of 300° -70° = 230° after a cooling time of 10 minutes. The cooling factor is ...

  cooling factor = 230/305

These values let us write the equation as ...

  T(t) = 305(230/305)^(t/10) +70

The temperature after 20 minutes is found using this equation:

  T(20) = 305(230/305)^(20/10) +70 = 305(46/61)^2 +70 = 243 27/61

  T(20) ≈ 243.4 . . . . degrees F

__

Additional comment

The cooling factor can be expressed as a value that lets the exponent be t. Often, it is written as (e^k), where ...

  k = 1/10·ln(230/305) ≈ -0.0282232

Then the equation is ...

  T(t) = 305·e^(-0.0282232t) +70

It could also be written as ...

  T(t) = 305(0.972171^t) +70

where 0.972171 = (46/61)^(1/10).
