Final answer:
To determine the measures of two complementary angles with a 46-degree difference, you can set up an equation and solve for the angles, resulting in approximately 22.0 degrees and 68.0 degrees.
Explanation:
Complementary angles are two angles that add up to 90 degrees. If the difference between them is 46 degrees, we can set up an equation to find their measures:
Let one angle be x. The other angle would then be 90 - x.
Given that the difference between them is 46, we have the equation: 90 - x - x = 46.
Solving the equation, the angles are approximately 22.0 degrees and 68.0 degrees.

which natural phenomenon is the best example of periodic behavior
Answer: The answer is the number of hours of daylight each day.
Step-by-step explanation: We are to give the best example of a natural phenomenon of periodic behavior.
A periodic behavior means the behavior which repeats itself in equal intervals of time or periods. Since we are talking about a natural phenomenon, so the rotation of earth around the sun can be an example.
In other words, we can say the number of hours of daylight each day will be the proper example, because the sun gives light for almost same number of hours each day.
Thus, the natural phenomenon is the number of hours of daylight each day.

A line has slope 56 and y–intercept −3. Which answer is the equation of the line? y=−3x+5/6 y=5/6x−3 y=3x+5/6 y=5/6x+3
Answer:
The answer is the second one for sure y=5/6x−3.
Step-by-step explanation:
The equation of the line is y = (5/6)x - 3 which is the correct answer would be option (B).
What is the equation?The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.
We have been given a line that has a slope of 5/6 and a y-intercept is -3.
Let the required line of the equation would be as
y = mx + c
Where m is the slope of the line
We have given the y-intercept is -3 which means the x-coordinates will be zero.
Substitute the value of x = 0 and y = -3 in the above equation to get c.
⇒ -3 = m(0) + c
⇒ -3 = c
The slope of the line m = 5/6 which is given in the question,
Substitute the value of m = 5/6 and c = -3 in the equation y = mx + c
⇒ y = (5/6)x - 3
Therefore, the equation of the line is y = (5/6)x - 3.

Alex had (3x + 1) yards of silk. He then purchases (x2 + 5x + 4) packages each containing (2x + 1) yards of silk. If he uses (2x3 + 8x2 + 10x + 4) yards of silk to make a kite, how much silk remains?
Final answer:
To find out the amount of silk remaining, we need to subtract the amount of silk used to make the kite from the total amount of silk Alex had before purchasing the packages. After performing the calculations, we find that Alex doesn't have any silk remaining.
Explanation:
To find out how much silk remains, we need to subtract the amount of silk used to make the kite from the total amount of silk Alex had before purchasing the packages. Let's first simplify the expressions:
Total silk Alex had = 3x + 1
Total silk purchased = (x^2 + 5x + 4) × (2x + 1)
Silk used for kite = 2x^3 + 8x^2 + 10x + 4
Now, substitute the given values of x:
Total silk Alex had = 3(1500) + 1 = 4501 yards
Total silk purchased = (1500^2 + 5*1500 + 4) * (2*1500 + 1) = 22537500 yards
Silk used for kite = 2(1500^3) + 8(1500^2) + 10(1500) + 4 = 53910002004 yards
Finally, subtract the silk used for the kite from the total silk Alex had:
Silk remaining = Total silk Alex had - Silk used for kite = 4501 - 53910002004 = -53910001403 yards
Since the result is negative, it means that Alex doesn't have any silk remaining.

Using the approximation 3.14 for pi, what is the radius of a circle with circumference 28.3 m?
Using π ≈ 3.14, the radius of a circle with circumference 28.3 m is approximately 4.5 meters.
Step 1:
Write down the formula for the circumference of a circle.
The formula for the circumference (C) of a circle is given by:
[tex]\[ C = 2 \pi r \][/tex]
Step 2:
Substitute the given value for the circumference into the formula.
Given [tex]\(C = 28.3\)[/tex] m, we use the approximation [tex]\(\pi \approx 3.14\)[/tex]:
[tex]\[ 28.3 = 2 \times 3.14 \times r \][/tex]
Step 3:
Solve for the radius (r).
Divide both sides of the equation by [tex]\(2 \times 3.14\)[/tex]:
[tex]\[ r = \frac{28.3}{2 \times 3.14} \][/tex]
Step 4:
Calculate the value of (r).
[tex]\[ r = \frac{28.3}{6.28} \][/tex]
[tex]\[ r \approx 4.5 \text{ m} \][/tex]
So, the radius of the circle with a circumference of 28.3 m, using the approximation [tex]\(\pi \approx 3.14\)[/tex], is approximately 4.5 meters.

Kristen lives directly east of the park. The football field is directly south of the park. The library sits on the line formed between Kristen’s home and the football field at the exact point where an altitude to the right triangle formed by her home, the park, and the football field could be drawn. The library is 2 miles from her home. The football field is 8 miles from the library.
Using Pythagoras theorem, we can find that the library is approximately 7.746 miles from the football field, which forms a right-angled triangle with Kristen's home and the park.
Explanation:This problem is a classic example of use of Pythagoras theorem in right-angle triangle. Here, the distances of Kristen's home, the park, and the football field form a right-angle triangle, with the distance from the park to the library acting as the altitude of the triangle. To find the distance from the library to the football field, we can use the relation:
[tex]\text{(Hypotenuse)}^2 = \text{(Base)}^2 + \text{(Perpendicular)}^2[/tex]According to the problem, The library is 2 miles from her home (Base), The football field is 8 miles from the library (Hypotenuse). So the distance from the library to the football field can be calculated as:
[tex]\text{Perpendicular} = \sqrt{(\text{Hypotenuse})^2 - (\text{Base})^2} = \sqrt{(8\text{ miles})^2 - (2\text{ miles})^2} = \sqrt{60} \approx 7.746 \text{ miles}[/tex]
So, the library is approximately 7.746 miles from the football field.
