The variables x and y are related proportionally. When x = 6, y = 16. Find y when x = 33.

Answers

Answer 1

Answer:

y=43

Step-by-step explanation:

y=x+10

y=33+10

y=43

Answer 2

To find the value of y when x=33, knowing that x and y are directly proportional, we first calculate the proportionality constant from the given values and apply it to find y=88 when x=33.

The task is to find the value of y when x is given, knowing that x and y are directly proportional. Thus, we first find the proportionality constant using the given values of x=6 and y=16. The formula for direct proportionality is y = kx, where k is the proportionality constant. Solving for k we get k = y/x => k = 16/6. Once we have the value of k, we can find y for x=33 by rearranging the formula to y = (16/6) * 33.

After performing the calculation, we find:

k = 16/6y when x=33 is y = (16/6) * 33

Therefore, y is 88 when x is 33, as they are directly proportional.

(x + 10) + (x + 10) = 90

90 - (10 + 10) = 70

70/2 = 35

x = 35

Have a great day!

Answer:

x = 35

Step-by-step explanation:

Since we know that this is a right angle, we know that the total has to equal 90 degrees. From there, we can make an equation:

(x+10) + ( x+10) = 90

2x +20 = 90

2x = 70

x = 35

By applying the Pythagorean theorem to both triangles and connecting them, we find that x is roughly 11.547 cm, establishing the relationship between the side lengths in these right triangles.

Let's explore the relationship between two right triangles, ABC and ACF, and calculate the value of x using the Pythagorean theorem.

Triangle ABC is a right triangle with sides BC and AB both measuring x cm. By applying the Pythagorean theorem (a^2 + b^2 = c^2), where c is the hypotenuse, in this case, AC, we find:

AC² = x² + x² = 2x²

This equation relates the lengths of the sides of triangle ABC.

Now, consider triangle ACF. It's also a right triangle with side CF measuring x cm and a hypotenuse AC, which is 20 cm long. Applying the Pythagorean theorem again:

20² = AC² + x²

Since we already established that AC² is 2x² from the first triangle, we can substitute it in:

20² = 2x² + x²

This equation connects the two triangles. To find the value of x, we need to solve this equation:

20² = 3x²

Now, isolate x:

x² = (20²) / 3

x² = 400/3

x = √(400/3)

x ≈ 11.547 cm

So, x is approximately 11.547 cm.

The Pyramid of Khafre in Egypt stands 471 feet tall. The sides of its square base are 705 feet in length. Find the lateral surface area of the Pyramid of Khafre. (Hint: Use the Pythagorean Theorem to find the pyramid’s slant height)

Answers

Answer:

Lateral surface area = 4 (1/2 × 705 × 588.30) = 829503 ft²

Step-by-step explanation:

The pyramid is a square base pyramid. The height = 471 ft. The sides of the square base pyramid = 705 ft.

To calculate the lateral area of the square base pyramid we have to know the slant height. The slant height can be known by using Pythagoras theorem to solve for it.

c² = a² + b²(Pythagoras theorem)

base = b = 705/2 = 352.50 ft

c² =  352.50² + 471²

c² = 124256.25 + 221841

c² = 346097.25

square root both sides

c = √346097.25

c = 588.300305966

c ≈ 588.30 ft

slant height = 588.30 ft

Lateral surface area  = sum of area of the 4 triangular faces

lateral surface area = 4 (1/2 × base × height)

Lateral surface area = 4 (1/2 ×705 × 588.30) = 829503 ft²

Numbers greater than or equal to 15950 and less than 16050.

Step-by-step explanation:

Given:

The town Diego lives in has a population of about 16,000

To fill: the blanks

Solution:

Numbers 15950, 15951, 15952, 15953,...., 16000, 16001, 16002,..., 16049 are rounded off to 16,000 when rounded to the nearest hundred.

In other language, numbers greater than or equal to 15950 and less than 16050

Numbers greater than or equal to 15950 and numbers less than or equal to 16049 will round round to 16000 when rounded to the nearest hundred.

To round to the nearest hundred :

When the value of the tens digit is greater than or equal to 5, it is rounded up to 1 and added to the hundred digit If the tens digit is less than 5, it is rounded to 0.15950, tens digit is 5, when rounded to 1 and added to the hundred digit, we have 16,00016049 ; tens digit is 4, it is rounded to 0 a d we have 16000

Therefore, Values below 15950 and beyond 16049 will not round to 16000(to the nearest hundred).

Graph a line that contains the point ( 3 , -6) and has a slope of 1/2

Answers

1/2x - 7.5Step-by-step explanation:The image below shows proof that the equation y = 1/2x - 7.5

Step-by-step explanation:

The equation of the line contains the point ( 3 , -6) graph is shown below.

Since the point (3, -6) lies on the line, we can use the point-slope form of linear equations to find the equation of the line, which is:

[tex]y - y_1 = m(x - x_1)[/tex]

where [tex](x_1, y_1)[/tex]  is the point on the line and m is the slope of the line.

Substituting in (3, -6) and m = 1/2, we get:

y - (-6) = 1/2(x - 3)

y + 6 = 1/2x - 3/2

y = 1/2x - 3/2 - 6

y = 1/2x - 9/2

To graph the line, we can start by plotting the point (3, -6). Then, we can use the slope to find another point on the line.

Since the slope is 1/2, it means that for every 1 unit we move up, we must also move 2 units to the right.

Therefore, we can move 2 units to the right and 1 unit up from (3, -6) to find the point (5, -5). We can then plot this point and connect the two points with a line.

Here is a graph of the line that contains the point (3, -6) and has a slope of 1/2:

The graph shows that the line passes through the point (3, -6) and has a positive slope.

What is the value of the discriminant of f?
How many distinct real number zeros does f have?

Answers

The discriminant of the quadratic function f(x) = -4x^2 + 10x - 8 is -28. Since the discriminant is negative, there are no distinct real number zeros for this function.

Your question involves finding the discriminant of the quadratic function f(x) = -4x2 + 10x - 8 and determining how many distinct real number zeros it has. The discriminant of a quadratic equation in the form ax2 + bx + c is given by b2 - 4ac. In your case, a = -4, b = 10, and c = -8. Let's calculate the discriminant:

b2 - 4ac = (10)2 - 4(-4)(-8)

b2 - 4ac = 100 - 128

b2 - 4ac = -28

Since the discriminant is negative (b2 - 4ac < 0), the quadratic function f(x) has no real number of zeros. Therefore, the graph of the function does not cross the x-axis, and there are no distinct real roots.

there is actually a formula to find the measurement of the hypotenuse called the pythagorean theorem

where a=measurement of one side

b=measurement of other
