Step-by-step explanation:

The satellites Sputnik, Yeltsin, and Plekov are in a great circle, which is a circular path on the surface of a sphere that passes through the center of the sphere. The circumference of this great circle is 24,900 miles, and the satellites orbit at a height of approximately 200 miles above the surface of the sphere.

If Sputnik is 2 miles from Yeltsin, and Yeltsin is 11,500 miles from Plekov, then the total distance from Sputnik to Plekov can be found by adding the distance between Sputnik and Yeltsin to the distance between Yeltsin and Plekov. So, the total distance is 2 miles + 11,500 miles = 11,502 miles.

However, this distance is not the direct distance between Sputnik and Plekov, since they are not on a straight line but on a curved path on the surface of the sphere. To find the actual distance between Sputnik and Plekov, we can use the formula for the great-circle distance between two points on a sphere, which is:

d = acos(sin(lat1) * sin(lat2) + cos(lat1) * cos(lat2) * cos(long2 - long1)) * R

where lat1 and lat2 are the latitudes of the two points, long2 - long1 is the difference in longitudes of the two points, R is the radius of the sphere, and acos is the inverse cosine function.

Using this formula, we can calculate the distance between Sputnik and Plekov to be approximately 26,156 miles.

The only way to graph or sketch a function by hand, is by finding some points on the graph and then connecting them.

To find the points we need to evaluate the quadratic equation.

if x = 0

y = 5*0^2 + 2 = 2

So we have the point (0, 2)

if x = 1

y = 5*1^2 + 2 = 7

So we have the point (1, 7)

if x = -1

y = 5*(-1)^2 + 2 = 7

So we have the point (-1, 7)

The number of inches Sami is taller to his younger sister as per their respective given heights is equal to 9 inches.

Height of Sami in feet and inches is equal to 5 feet 8 inches

Height of Sami's younger sister is equal to 4 feet 11 inches

Convert all height into inches we get,

1 feet = 12inches

5 feet = 5 × 12 inches

          = 60 inches

4 feet = 4 × 12 inches

          = 48 inches

Number of inches Sami's is taller than his younger sister is equal to

= ( 5 feet 8 inches ) - ( 4 feet 11 inches )

= ( 60 + 8 ) inches - ( 48 + 11 ) inches

Answer:

Step-by-step explanation:

Let's call the present value of the loan P. The payments of $1,550 in 1 year and $2,400 in 4 years can be expressed as an ordinary annuity with semi-annual payments. We can calculate the present value of this annuity using the formula:

PV = A * (1 - (1 + r)^-n) / r

where

A = $1,550 / 2 = $775 (semi-annual payment)

n = (4 x 2) + 2 = 10 (number of semi-annual periods)

r = 0.045 / 2 = 0.0225 (semi-annual interest rate)

So,

PV = $775 * (1 - (1 + 0.0225)^-10) / 0.0225 = $8,100.40

Thus, the present value of the loan is P = $8,100.40.

Next, we can calculate the present value of the payment of $1,050 in 24 months and the balance in 30 months.

The payment of $1,050 in 24 months can be expressed as a single amount due in 24 months. The present value of this payment can be calculated as:

PV = $1,050 / (1 + 0.0225)^(24/2) = $1,000.54

So, the balance of the loan after this payment would be P - $1,000.54 = $8,099.86.

The balance in 30 months can be expressed as an ordinary annuity due with semi-annual payments. We can calculate the present value of this annuity using the formula:

PV = A * (1 - (1 + r)^-n) / r

where

A = ($8,099.86) / 6 = $1,349.98 (semi-annual payment)

n = 6 (number of semi-annual periods)

r = 0.0225 (semi-annual interest rate)

So,

PV = $1,349.98 * (1 - (1 + 0.0225)^-6) / 0.0225 = $7,999.86

Therefore, the payment required in 30 months for the rescheduled option to settle the loan is $1,349.98 per semi-annual period.

The solutions to the quadratic equation 25 = (x + 9)² are x = -4 and x = -14.

What is quadratic equation?

A quadratic equation is a polynomial equation of degree 2, which means that the highest power of the variable in the equation is 2. The general form of a quadratic equation is:

ax^2 + bx + c = 0

where x is the variable, and a, b, and c are constants, with a not equal to 0. The quadratic equation can have two solutions, one solution, or no real solutions, depending on the values of a, b, and c.

Starting with the given equation:

25 = (x + 9)²

We can start by taking the square root of both sides of the equation, which gives us:

±5 = x + 9

Next, we can isolate x by subtracting 9 from both sides of the equation:

x = -9 ± 5

This gives us two solutions:

x = -9 + 5 = -4

or

x = -9 - 5 = -14

Therefore, the solutions to the quadratic equation 25 = (x + 9)² are x = -4 and x = -14.

Answer:

the least possible number of marbles in the bag is 12.

Step-by-step explanation:

As for the question about the marbles, let's call the number of red marbles "x". Then the number of white marbles is 4x, the number of blue marbles is 5x, and the number of green marbles is (1/2) * 5x = 2.5x.

The total number of marbles in the bag is x + 4x + 5x + 2.5x = 12.5x.

To find the least possible number of marbles, we need to find the smallest possible value of x, which will give us the smallest total number of marbles. Since x represents the number of red marbles, it must be a positive integer. The smallest positive integer value of x is 1.

So, if there is one red marble, there are 4 white marbles, 5 blue marbles, and 2.5 green marbles. The total number of marbles in the bag is 1 + 4 + 5 + 2.5 = 12.5.

Therefore, the least possible number of marbles in the bag is 12.

The balance in the account after 1 year due to continuous compounding is approximately $1030.45 and AYP is 3.04%.

What is meant by continuous compounding?

If compound interest is calculated and reinvested into the balance of an account across an essentially unlimited number of periods, continuous compounding is the mathematical limit that compound interest can reach. Continuous compounding determines interest by assuming constant compounding across an infinite number of periods, as opposed to computing interest on a finite number of periods, such as annually or monthly.

Given,

rate per period  = 3%

Principal amount = $1000

Compounding is done after 1,5 and 20 years.

But we are asked to find the amount after continuous compounding after 1 year.

The formula of the amount after continuous compounding is:

[tex]A = Pe^{rt}[/tex]

where A = amount after continuous compounding

        r = rate of period

     t = time period

    P  = principal amount

[tex]A = Pe^{rt} = 1000e^{0.03*1}[/tex] = $1030.45

Annual yield formula (AYP) = [tex](1+\frac{r}{n} )^n-1[/tex]

n = times it compounds per year = 365

r = 0.03

AYP = [tex](1+\frac{0.03}{365} )^{365}-1 = 0.0304[/tex]

                                  = 3.04%

In the vertex form the equation can be rewritten as x = 1×(y - 2)² + 5

The equation is given in the standard form y²-4y-x+9 = 0 and we have to convert it into vertex form

So basically, the general vertex form of any equation is x = a(y - k)² + h

⇒ y²-4y-x+9 = 0

Shifting the x to RHS,

⇒ x = y²- 4y + 9

Writing y²- 4y in the form of (a-b)²,

⇒ x = y²- 4y + 4 + 5

Angles that are complementary are those whose sum is 90 degrees. If the smaller angle has a measure of x, then the complementary angle's measure is 90 - x.

The issue shows that the greater angle (x + 17.4) is 17.4 degrees larger than the corresponding angle's measurement (90 - x). To find x, we can construct the following equation:

x + 17.4 = 90 - x + 17.4
