Nasim needs  to  invest $20203.5 for the value of the account to reach $27000.

It is the interest that a person can earn from a particular amount of deposit money. And the deposit is increased gradually over the time.

given, interest rate = r = 5.8%

final amount = A = $27000

time period elapsed, t = 5 years

number of times interest applied per time period, n= 365 times

as the interest compound daily so per year interest applied = 365 days = 365 times [ as 1 year = 365 days]

we need to determine the initial invested money, P.

From the compound interest formula, A = P (1 +r/n) ∧nt

                                                  $27000 = P (1+ 0.058/365) ∧365×5

The sum of first square number and the first cube number would be 2.

What is the cube of a number?

A cube of a number is the number multiplied by itself three times. For example, the cube of 2 is 2 x 2 x 2 = 8. It can also be represented mathematically by raising the number to the power of 3, such as x^3 where x is the number you want to find the cube of.

The first square number is 1^2 = 1 and the first cube number is 1^3 = 1. Therefore, the sum of the first square number and the first cube number is 1 + 1 = 2.

The probability of having a total of more than 180 arrivals at the toll in the next two hours is 0.84.

The time taken to assemble follows the normal distribution.

Given mean i.e. μ = 100

Given standard deviation i.e. σ = 40

The normal random variable of a standard normal distribution is called a standard score or a z-score. Every normal random variable X can be transformed into a z score via the following equation:

z=(X−μ)/σ

where X is a normal random variable, μ is the mean of X, and σ is the standard deviation of X.

For X=180

Z=(180−100)/40= 2

For X=2

Z=(2-2)/2=0

P(a<X<b)=P(X<b)–P(X<a)

P(20<X<22)=P(X<180)−P(X<2)

Here we have given that the number of arrive at a highway toll in an hour is independent of other hours and is well-estimated by a Normal distribution with an average of 100 cars per hour and standard deviation 40 cars.

Which means that

mean  = 100

And the value of standard deviation = 40

Now, we have to use the normal random variable of a standard normal distribution is called a standard score or a z-score.

Then the value of z score is calculated as

The system does appear to have a solution after the changes.

The equation of the orange line after the changes is y = -x - 3. The system appears to have a solution after the changes because the equations for both lines are in the same form. The blue line has a slope of -5 and the orange line has a slope of -1. This means that the lines have the same slope and the same y-intercept. This means that the two lines are parallel and will intersect at the point (-3,3).

To calculate the point of intersection, we can plug in -3 for x in both equations and solve for y.

For the blue line: y = -(-3)^5 = 3

For the orange line: y = -(-3) - 3 = 3

The transformation of the function is a reflection along the vertical y axis

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.

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

Given data ,

Let the function be represented as f ( x )

Now , the transformed function is given as g ( x )

The function g ( x ) has the x coordinates as the additive inverse

So , it must be a reflection transformation

And , the axis of transformation is y axis

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

The simple interest gained on $1050 deposited at an interest rate of 2% for 9 months = $ 15.75.

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.

The formula for simple interest is given by

Simple interest = PRT/100  

Where, P = Principal amount

R = Rate of interest

T = Time period

Here we have

$1050 deposited at an interest rate of 2% for 9 months.  

=> Principal amount, P = $ 1050

=> Time period, T = 9 months = 9/12 years

=> Rate of interest, R = 2 %

By the given formula,

Simple interest = 1050(2)(9/12)/100  

= 105(9/6)/10  

= 105(3/2)/10  

= 105(1.5)/10

= 15.75

The expression startroot 64 r superscript 8 baseline endroot can be written as (64)1/8r8.

This expression is asking for us to take the eighth root of 64, and then multiply it by 8. To solve this we can use the formula for radicals, which states that the nth root of a number a is equal to a1/n. In this case, n is equal to 8, and a is equal to 64. Therefore, the expression can be rewritten as 641/8 x 8. This simplifies to 8r2.

To calculate this, we first need to calculate the eighth root of 64, which can be done by raising the number to the power of the reciprocal of the root. In this case, we need to calculate 64^1/8. We can use a scientific calculator to find that the eighth root of 64 is 2. To finish the calculation, we simply multiply 2 by 8, which gives us 16. We can rewrite 16 as 8r2, which is the answer to the expression.

We know that 64 is square of 8.

8^2 = 64

So, we can write given expression as,

√(64r^8)

= √(8^2r^8)

We know that for the properties of exponents i.e., non-zero numbers a, m,n

(a^m)^n = a^(m * n)                    ............(1)

So, √[8^2r^(2 * 4)]

= √[8^2(r^4)^2]            

= √((8r^4)^2)

Square-root is nothing but the 1/2 power of number/expression.

i.e., √((8r^4)^2)

Therefore, exterior angle theorem can be used to find the angle x.

The triangle is a right angle triangle.

A right angle triangle is a triangle that has one of its angles as 90 degrees.

Therefore, let's find the angle x using exterior angle theorem.

Using sine and cosine law, the value of x is 7.2 unit

Cosine law is a mathematical formula used to calculate the sides and angles of a triangle when the lengths of all three sides are known. It states that the square of a side of a triangle is equal to the sum of the squares of the other two sides minus twice the product of those sides and the cosine of their included angle.

Using cosine law, we can find the length of A which will in turn assist us in finding the value of x

a² = 12² + 10² -2(12)(10) cos80

a² = 202.32

a = √202.32
