The balance after 6 years on an account that pays 5.5% annual interest compounded continuously with an initial deposit of $975 is $1,356.19.

Continuous compounding involves calculating the interest earned on a principal amount continuously over time, which results in a higher overall balance than other compounding frequencies.

Using the formula A = Pe^(rt), where A is the final balance, P is the initial deposit, r is the interest rate, and t is the time, we can calculate the balance after 6 years as A = 975e^(0.055*6) = $1,356.19. Therefore, the correct answer is option D, $1,356.19.

So, the standard parametric equations for the line are: x = -7 + 3t; y = -5 + 6t; z = 8 + 6t.

To find the standard parametric equations for the line, we can use the point-slope form of the equation of a line.

The given point on the line is (-7, -5, 8), and the line is parallel to the vector 3i + 6j + 6k.

Using the point-slope form, the equations can be written as:

x = x₁ + at

y = y₁ + bt

z = z₁ + ct

where (x₁, y₁, z₁) is the given point and (a, b, c) are the components of the parallel vector.

Substituting the values:

x = -7 + 3t

Answer:

Step-by-step explanation:

The problem shows a 90° angle split by a ray, we know that both angles are equal to 90° because the whole is equal to the sum of its parts therefore adding 6b+7 and 7b-8 gives us 90° which is simplified as

13b°-1°= 90°

add 1  to both sides

13b°-1° + 1° = 90° +1°

13b° = 91°

divide by 13

13b°/13 = 91°/13

b= 7°

Answer:

-2

Step-by-step explanation:

The value of c is -4, therefore the additive inverse should be added to get the answer 0

The roots of the quadratic equation x² – 2x + c = 0 are a and –b. Then the value of c is a² – 2a.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

For which values of c does the quadratic equation

x² – 2x + c = 0 ...1

Two roots of opposite signs

Let the two roots of the opposite signs be a and –b

x = a, –b

Then we have factorized the equation,

(x + b)(x – a) = 0

On solving, we have

x² + (b – a)x – ab = 0 ...2

In comparing equation 2 with equation 1, we have

⇒  b – a = –2

⇒ b = –2 + a

and

⇒ c = a(a – 2) = a² – 2a

The area of the remaining rectangular plot of land is 4680m²

Area of rectangle:

Area of rectangle means the area covered by the rectangle.

The formula for area of rectangle is

A = l x b

where,

l is the length of the rectangle

b is the breadth or width of the rectangle

Given,

A rectangular plot of land measures 40.0 m by 120.0 m, with a parcel 10.0 m by 12.0 m out of one corner for an electrical transformer.

Here we need to find the remaining area of the rectangular plot land.

For that first, we have to find the area of each separately,

Like,

The area of the rectangular plot is,

A₁ = 40.0 x 120.0 m²

A₁ = 4800m²

Similarly, the area of the electric transformer is,

A₂ = 10.0 x 12.0 m²

A₂ = 120m²

Now the remining area is,

A = A₁ - A₂

A = 4800 - 120 m²

A = 4680m²

Therefore, the area of the remaining rectangular plot is 4680m².

Answer:

  P = 0.14t +2.25

Step-by-step explanation:

The statement that "the price of a school lunch ... has risen at a constant rate" is telling you that the price can be modeled by a linear equation. If P is the price, and t is years after 2012, you are given two points on the line:

  (t, P) = (0, 2.25) and (7, 3.20)

You can use these points to find the equation of the line in the usual way.

  m = (y2 -y1)/(x2 -x1) . . . . . . slope of a line through (x1, y1) and (x2, y2)

  m = (3.20 -2.25)/(7 -0) = 0.95/7 ≈ 0.14

To solve this problem, let us first find the probability that x < y when point (x, y) is randomly selected from inside the rectangle. Then, using the area of the rectangle, normalize the probability.

The probability that x < y is 1/8.

To find the probability that x < y when a point is randomly chosen from within the rectangle. Let A be the area of the region where x < y, and B be the area of the rectangle. Then, the probability that x < y is given by P(x < y) = A/B. To find A and B, let us first look at the line x = y, which passes through (0,0) and (1,1) and separates the rectangle into two regions: Region I: The area to the right of the line x = y, where x > y. Region II: The area to the left of the line x = y, where x < y. region xy plane Region I has area B - A, and Region II has area A. Hence, B - A + A = B, which implies A/B = A/(B - A) = 1/2. Therefore, we only need to find A.

Let C be the triangle with vertices (0,0), (1,0), and (1,1). This triangle has area 1/2. Since the rectangle has height 1, the line x = y intersects the rectangle at a height of 1/2, which means that A is the area of the trapezoid with vertices (1/2, 0), (1, 0), (1, 1), and (1/2, 1/2).trapezoid xy plane. To find the area of this trapezoid, we can split it into a rectangle and a right triangle, as shown below: split trapezoid xy plane. The rectangle has base 1/2 and height 1, so its area is 1/2. The triangle has base 1/2 and height 1/2, so its area is 1/8. Hence, the area of the trapezoid is 1/2 + 1/8 = 5/8. Therefore, the probability that x < y is P(x < y) = A/B = (5/8) / 4 = 1/8.

The solution of the equation is x=±i or x=±i√2.

Given that the equation is x⁴+3x²+2=0 and use u substitution method to solve.

We can rewrite our given equation as:

(x²)²+3x²+2=0

Let's assume that the (x²)=u.

The given equation is rewritten as u²+3u+2=0.

Factorize the quadratic equation by adding or subtracting two number that gives the sum of 3u and product 2u² as

u²+2u+u+2=0

u(u+2)+1(u+2)=0

Taking out (u+2) as common and get

(u+2)(u+1)=0

Compare each equation with 0 and get

u+2=0 or u+1=0

u=-2 or u=-1

Performing back substitution by substituting the values of u in x²

when u=-1 then x is

x²=-1

x=±√(-1)

As we know that √(-1)=i.

So, we get

x=±i

And when u=-2 then x is

x²=-2

x=±√(-2)

As we know that √(-1)=i.

So, substituting this, we get

x=±i√2

Answer: P(t) = $1000*2^t

Step-by-step explanation:

Ok, we know that in the week 1 the price is: p = $1000

After one week, the price doubles, so here we have: p = 2*$1000

After another week, the price doubles again, here the price is:

p = 2*(2*$1000) = $1000*2^2

Here we already can see the relation, for each week, we multiply the previous price by two, which will increase the exponent in the two by 1 unit.

Then, for week number t, the price will be:

P(t) = $1000*2^t

By respecting the given ratio:

2) 4 of blue paint and 6 of yellow.

3) 2 cans of blue paint and 3 of yellow.

We know that on day 1 he uses:

On day 2 he uses:

Adding that we get:

He initially has 20 cans of yellow, so he has left:

20 - 15 = 5 cans of yellow.

He initially has 14 cans of blue, so now he has:

14 - 10 = 4

4 cans of blue paint.

The original ratio is:

6 yellow to 4 blue.

The quotient gives: 6/4 = 3/2

The time the plane arrives at the London airport from the airport in Manchester, found using the kinematic equation for speed, and the conversion of the units from hours to minutes is 11:40 a.m.

The kinematic equations describe the motion of an object that moves with constant acceleration.

Distance from the London airport to the Manchester airport, D = 200 miles

The average speed of the plane, v = 120 mph

Time the plane leaves Manchester airport = 10 a.m.

The kinematic equation that can be used to find the time of flight is presented as follows;

\(Speed, \, v = \dfrac{Distance, \, D }{Time, \, t}\)

Therefore;

\(t = \dfrac{D}{v}\)

The time of flight is therefore;

\(t = \dfrac{200}{120} = \dfrac{5}{3} = 1\dfrac{2}{3}\)

The time of flight is \(1\frac{2}{3}\) hours or 5/3 hours which in minutes is therefore:

\(t = \dfrac{5}{3} \, hr \times 60 \, min/hr= 100 \, min\)

The time of arrival is 10 a.m. + 1 hour 40 minutes = 11:40 a.m.

The probability of a penny falling out is 0.3 or 30%.

The study of probability is a branch of mathematics that focuses on calculating the possibility or chance that an event will occur. It is expressed as a number between 0 and 1, with 0 denoting impossibility and 1 denoting certainty, and numbers in between denoting likelihood.

The number of favourable outcomes for an event A divided by the total number of possible outcomes is the definition of P(A), which stands for probability. The classical definition of probability is this.

From the given table we see that, the total coins in the cup are:

3+5+2+1=11.

Now, for the number of penny are: 3

Thus,

P(penny falls out) = 3/10 = 0.3

C) indicates the difference in the slopes of the two regressions.

In the given regression model, ß3 is the coefficient of the interaction term between X and D, which is (Xi x Di). The interaction term shows how the effect of X on Y changes when D changes from 0 to 1.

Therefore, the coefficient ß3 indicates the difference in the slopes of the two regressions (when D = 0 and D = 1), which represents the effect of the interaction between X and D on Y.

Option A is incorrect because the slope of the regression when D=1 is given by the coefficient ß1 (the coefficient of X), not by ß3.

Option B is incorrect because the standard error of the coefficient ß3 can be normally distributed in large samples, even if D is not normally distributed.

To show that the general term of the quadratic number pattern is given by \(tn = n^2 + 4n - 12\) , we need to find a quadratic expression that fits the given pattern.

Let's examine the given sequence: -7, 0, 9, 20. We notice that each term is increasing by a certain amount.

First, let's find the differences between consecutive terms:
0 - (-7) = 7
9 - 0 = 9
20 - 9 = 11

We observe that the differences between consecutive terms are not constant, so this indicates that the sequence is not linear.

To determine if the sequence follows a quadratic pattern, let's find the second differences:
9 - 7 = 2
11 - 9 = 2

The second differences are constant, which suggests a quadratic pattern.

Now, let's find the quadratic expression. We know that the general term of a quadratic sequence can be written as \(tn = an^2 + bn + c\), where a, b, and c are constants to be determined.

Using the given terms, we can form three equations:

1.\(For n = 1: -7 = a(1)^2 + b(1) + c\)
2. \(For n = 2: 0 = a(2)^2 + b(2) + c\)
3.\(For n = 3: 9 = a(3)^2 + b(3) + c\)

Simplifying these equations, we get:
1. a + b + c = -7
2. 4a + 2b + c = 0
3. 9a + 3b + c = 9

Solving this system of equations, we find a = 1, b = 4, and c = -12.

Therefore, the general term of the quadratic number pattern is given by\(tn = n^2 + 4n - 12\).

The general term of the quadratic number pattern is \(tn = n^2 + 4n - 12\).
