===============================================

Work Shown:

(1 inch)/(40 miles) = (5 inches)/(x miles)

1/40 = 5/x

1*x = 40*5 .... cross multiply

x = 200 miles

------------

We could also look at it like this:

1 inch = 40 miles

5*(1 inch) = 5*(40 miles) .... multiply both sides by 5

5 inches = 200 miles

In the first line, we are going to have that if you put 7 then to have the sum rigth the next space have to be 9, following that idea the space down of the 9 have to be also 7 and the first space on the second line have to be 19. So we are going to have 7 + 9 = 16 in the first line and in the second line 19 - 7 = 12, and the other two operations are going to be solve also 7 + 19 = 26 and 9 + 7 = 16.

Then the answer is 7 + 9 = 16 in the first line and in the second line 19 - 7 = 12.

A 1x25 Playfair matrix results in a substitution system called the "Playfair Cipher."

This cipher is a digraph substitution cipher, where pairs of letters are encrypted using a 5x5 matrix created from a keyword. The matrix is filled with unique letters of the alphabet, and "I" and "J" are typically combined into one slot. The Playfair Cipher encrypts pairs of letters by following specific rules: if the letters are in the same row or column, they're replaced by the letters to their immediate right or below, and if they form a rectangle, they're replaced by the letters on the same row but in the opposite corners. This cipher provides a more secure encryption compared to simple substitution ciphers, as it encrypts pairs of letters instead of single characters.

Step-by-step explanation:

The formula for calculating future value:

FV = P (1 + r/n)^nm

FV = Future value  

P = Present value  

R = interest rate  

m = number of compounding

N = number of years  

1. 1( 1 + 0.24 /12)^12 = $1.27

2. 5000 ( 1 + 0.12 /4)^( 5 x 4) = $9030.56

You have the following expression:

2.5 x 10⁴ - 1.5 x 10³

in order to simplify the previous expression, consider that the factors with base 10 have to have the same exponent. You can write the second term as a factor with 10⁴ if you write 1.5 as 0.15 (if you increase the exponent you move the decimal point to the left). Then, you can subtract the coefficients of the term and put the same factor x 10⁴:

Then, you have:

1.5 x 10³ = 0.15 x 10⁴

2.5 x 10⁴ - 0.15 x 10⁴ = 2.35 x 10⁴

Hence, the asnwer is:

2.35 x 10⁴

A scatter chart is a graphical representation of a set of observations where one variable is plotted on the x-axis and the other variable is plotted on the y-axis. Scatter charts are useful in identifying patterns and relationships between the two variables. The strength and direction of the relationship between the variables can be determined by examining the pattern of the scatter chart. If the data points are tightly clustered around a straight line, then there is a strong linear relationship between the two variables. On the other hand, if the data points are scattered without any pattern, then there is no relationship between the two variables.

The expression √(1 - cos^2θ) represents the positive square root of the difference between 1 and cos^2θ. Since sine can be positive or negative depending on the quadrant, the sign of sinθ will depend on the quadrant in which θ lies.

To express the first trigonometric function sinθ in terms of the second trigonometric function cosθ, we can utilize the fundamental trigonometric identity known as the Pythagorean identity. This identity relates the values of sine and cosine and is given by:

sin^2θ + cos^2θ = 1

Rearranging this equation, we can solve for sin^2θ:

sin^2θ = 1 - cos^2θ

Taking the square root of both sides, we get:

sinθ = √(1 - cos^2θ)

Therefore, we have expressed sinθ in terms of cosθ using the Pythagorean identity.

This expression allows us to find the value of sinθ when we know the value of cosθ. By substituting the given value of cosθ into the expression, we can calculate the corresponding value of sinθ.

It is important to note that the expression √(1 - cos^2θ) represents the positive square root of the difference between 1 and cos^2θ. Since sine can be positive or negative depending on the quadrant, the sign of sinθ will depend on the quadrant in which θ lies.

In summary, sinθ can be expressed in terms of cosθ using the Pythagorean identity as sinθ = √(1 - cos^2θ). This expression provides a way to find the value of sinθ when the value of cosθ is known, allowing us to establish a relationship between the two trigonometric functions.

The correlation coefficient of 0.90 indicates a strong positive linear correlation between happiness and GPA of high school students.

A correlation coefficient measures the strength and direction of the relationship between two variables. In this case, the correlation coefficient of 0.90 indicates a strong positive linear correlation between happiness and GPA of high school students.

A positive correlation means that as one variable (in this case, happiness) increases, the other variable (GPA) also tends to increase. The magnitude of the correlation coefficient, which ranges from -1 to 1, represents the strength of the relationship. A value of 0.90 indicates a very strong positive linear correlation, suggesting that there is a consistent and significant relationship between happiness and GPA.

This means that as the level of happiness increases among high school students, their GPA tends to be higher as well. The correlation coefficient of 0.90 suggests a high degree of predictability in the relationship between these two variables.

It is important to note that correlation does not imply causation. While a strong positive correlation indicates a relationship between happiness and GPA, it does not necessarily mean that one variable causes the other. Other factors or variables may also influence the relationship between happiness and GPA.

Hope I could help :)

the values of a and b are a = 3/2 and b = -1/6, respectively.

To find the values of a and b, we need to use the given equation of the tangent line and the information about the graph of the function.

First, let's find an expression for f'(x), the derivative of the function f(x) = br².

Differentiating f(x) = br² with respect to x, we get:

f'(x) = 2br

Next, we can find the slope of the tangent line at x = 2 by evaluating f'(x) at x = 2.

f'(2) = 2b(2) = 4b

We know that the equation of the tangent line is 2x + 3y = a. To find the slope of this line, we can rewrite it in slope-intercept form (y = mx + c), where m represents the slope.

Rearranging the equation:

3y = -2x + a

y = (-2/3)x + (a/3)

Comparing the equation with the slope-intercept form, we see that the slope, m, is -2/3.

Since the slope of the tangent line represents f'(2), we have:

f'(2) = -2/3

Comparing this with the expression we derived earlier for f'(2), we can equate them:

4b = -2/3

Solving for b:

b = (-2/3) / 4

b = -1/6

Now that we have the value of b, we can substitute it back into the equation for the tangent line to find a.

Using the equation 2x + 3y = a and the value of b, we have:

2x + 3y = a

2x + 3((-1/6)x) = a

2x - (1/2)x = a

(3/2)x = a

Comparing this with the slope-intercept form, we see that the coefficient of x represents a. Therefore, a = (3/2).

So, the values of a and b are a = 3/2 and b = -1/6, respectively.

8. Image below!

9. 134 feet

10. Below.

11. The answers represent the timings at which the rocket was at height 164 feet.

12. 5.702s

Step-by-step explanation:

8. Image below

9. \(f(1)= -16(1)^2+100(1)+50 = 134\)

I'm doing this in a rush but I can tell you what you can do for the rest.

10. Use the quadratic formula

\(164 = -16x^2+100x+50\\\\0 = -16x^2+100x-214\\\\\)

And set a= -16, b=100, c=-214

You'll get two x-values.

11. The answers represent the timings at which the rocket was at height 164 feet.

12. Hitting the ground means the height is equal to 0. So...

\(0 = -16x^2+100x+50\\\)

Using the quadratic formula you get

x=5.702s

and

x= 0.548s

This means the rocket hits the ground at 5.702s.

Step-by-step explanation:

1.

the indicated point in the middle is the center point of the circle.

the line perpendicular to a chord going through that center solid the chord in half.

so,

x = 9

2.

Pythagoras

c² = a² + b²

13.5² = x² + 10.4²

182.25 = x² + 108.16

x² = 74.09

x = 8.607554821...

3.

Intersecting Chords Theorem

(part one of chord 1)×(part two of chord 1) =

= (part one of chord 2)×(part two of chord 2)

6x = 10×9 = 90

x = 90/6 = 30/2 = 15

4.

Intersecting Chords Theorem again

x(x+3) = 4×10 = 40

x² + 3x = 40

x² + 3x - 40 = 0

generation solution to a quadratic equation

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 3

c = -40

x = (-3 ± sqrt(3² - 4×1×-40))/(2×1) =

= (-3 ± sqrt(9 + 160))/2 = (-3 ± sqrt(169))/2 =

= (-3 ± 13)/2

x1 = (-3 + 13)/2 = 10/2 = 5

x2 = (-3 - 13)/2 = -16/2 = -8

negative values for a length do not make sense, so x = 5 is our solution

Intersecting Chords Theorem

(x+1)×4 = (x-1)×5

4x + 4 = 5x - 5

If a single card is drawn from a standard deck of 52 cards, the probability it will be a card with a number less than 5 is 4/13.

Probability measures how likely an event occurs. The probability of an event A is defined as:

P(A) = number of ways A can occur / total possible outcomes

In the given problem, let an ace card is considered as 1. Then, for each suit of cards, the card numbers which are less than 5 are cards number: 1, 2, 3, 4.

There are 4 suits, hence:

number of ways the event can occur = 4 x 4 = 16

total possible outcomes = 52

The sum of all two-digit numbers that have exactly three factors is 126.

To find the sum of all two-digit numbers that have exactly three factors, we need to determine which numbers satisfy this condition.

A number has exactly three factors if it is a perfect square. In other words, the number must be the square of a prime number.

The prime numbers less than 10 that have two-digit squares are 4, 5, 6, and 7. So we need to find the sum of their squares: 4^2 + 5^2 + 6^2 + 7^2 = 16 + 25 + 36 + 49 = 126.
