Sam is using a repeating pattern. The rule is "Blue Tile, White Tile, Black Tile." If he uses 85 tiles, how many will be black?
Answers
the answer is 42 times because he uses blue before black so you just needs to divide two by 85 which gives you 42.5 but 42 is the answer because when you reach 85 he will use blue tile so 42 is the answer so the answer is half of 42

Graph the image of S(-7,-1) after a rotation 270° clockwise around the origin
Answers
The graph of the image point S' is (2.24, -6.93) on the coordinate plane.
Describe Graph?A graph is a visual representation of data that shows the relationship between different variables or sets of data. Graphs can be used to display information in a way that is easy to understand and interpret, and they are often used to summarize complex data sets.
There are many different types of graphs, including:
Line graphs: These graphs show changes in data over time by connecting data points with straight lines.
Bar graphs: These graphs use bars to represent different categories or data sets, with the height or length of each bar indicating the value of the data.
Pie charts: These graphs use slices of a circle to represent different proportions of a data set, with each slice representing a different category or value.
Scatter plots: These graphs show the relationship between two different variables by plotting each data point on a two-dimensional plane.
To graph the image of S(-7,-1) after a rotation of 270° clockwise around the origin, we can use the following steps:
Plot the point S(-7,-1) on the coordinate plane.Draw the line connecting the origin (0,0) and the point S(-7,-1).The angle between the x-axis and the line connecting the origin and S is θ = arctan(-1/-7) = 8.13° (measured counterclockwise from the x-axis).To rotate the point 270° clockwise around the origin, we need to add 270° to the angle θ, which gives us a new angle of 278.13° (measured counterclockwise from the x-axis).The distance from the origin to the point S is r = √((-7)² + (-1)²) = √(50).Using polar coordinates, we can represent the point S as (r, θ) = (√(50)., 8.13°) in standard position.To rotate the point S by an angle of 270° clockwise, we can subtract 270° from the angle θ, which gives us a new angle of -261.87°.Using polar coordinates again, we can represent the image point S' as (r, θ) = (√(50)., -261.87°) in standard position.Converting back to rectangular coordinates, we get S'(2.24, -6.93), which is the image of S(-7,-1) after a rotation of 270° clockwise around the origin.Therefore, the graph of the image point S' is (2.24, -6.93) on the coordinate plane.

Answers
Step-by-step explanation:
it seems you solved the tricky part yourself already.
just to be sure, let's do the first derivative here again.
the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...
f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =
= 3t⁴ + 18t³ + 24t² + 18t + 21
f'(t) = 12t³ + 54t² + 48t + 18
and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).
we simply put the input number (2) at every place of the input variable (t).
so,
f'(2) = 12×2³ + 54×2² + 48×2 + 18 = 96 + 216 + 96 + 18 =

which earns 11% per year. In 20 years, how
much will Natalie's investment be worth if
interest is compounded monthly? Round to the

Answers
Answer:
We can use the formula for compound interest to find the future value (FV) of Natalie's investment:
FV = P * (1 + r/n)^(n*t)
Where:
P is the principal amount (the initial investment), which is $2,000 in this case
r is the annual interest rate as a decimal, which is 11% or 0.11
n is the number of times the interest is compounded per year, which is 12 since interest is compounded monthly
t is the number of years, which is 20
Substituting the values into the formula, we get:
FV =

By translation, the image of the triangle X is equivalent to the triangle E.
How to determine the image of a figure by rigid transformations
Herein we find the representation of a triangle, whose vertices are described below:
A(x, y) = (5, 5), B(x, y) = (5, 6), C(x, y) = (7, 5)
Whose image must be determined by a rigid transformation known as translation:
P'(x, y) = P(x, y) + T(x, y)
Where:
P(x, y) - Original point.P'(x, y) - Image of the point.T(x, y) - Translation vector.Now we proceed to determine the images of the vertices of the triangle:
A'(x, y) = (5, 5) + (4, - 3)
A'(x, y) = (9, 2)
B'(x, y) = (5, 6) + (4, - 3)
B'(x, y) = (9, 3)
C'(x, y) = (7, 5) + (4, - 3)
C'(x, y) = (11, 2)

The measures of the angles of △ABC are given by the expressions in the table.
Answers
The angles of the triangle are 125 degrees, 20 degrees, and 35 degrees.
Define triangles.A triangle is a closed geometric shape with three sides, three angles, and three line segments. Three non-collinear points are joined by line segments to create the simplest polygon, which has three non-collinear points.
Triangles can be categorized according to the size of their sides and angles. Triangles can be categorized as equilateral (all sides are equal in length), isosceles (both sides are equal in length), or scalene based on their sides (all sides are different in length). Triangles can be categorized as acute (all angles are less than 90 degrees), obtuse (one angle is greater than 90 degrees), or right (one angle is greater than 90 degrees) (one angle is exactly 90 degrees).
In any triangle, the sum of the three interior angles is always 180 degrees. Therefore, we can write:
a + b + c = 180
Substituting the given values, we get:
(6x-1) + 20 + (x+14) = 180
Simplifying and solving for x, we get:
7x + 33 = 180
7x = 147
x = 21
Now that we have the value of x, we can substitute it back into the expressions for the angles to find their values:
angle a = (6x-1) = (6*21-1) = 125 degrees
angle b = 20 degrees
angle c = (x+14) = (21+14) = 35 degrees
Therefore, the angles of the triangle are 125 degrees, 20 degrees, and 35 degrees.

3 6 9 12 15 18 21 24 27 30 is odd or even numbers?
Answers
Answer: Half of them are even and half of them are odd.
Step-by-step explanation:
The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.
The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.
Therefore, out of the given numbers, half of them are even and half of them are odd.

Find the probability of no more than 2
successes in 5 trials of a binomial
experiment in which the probability of
success in any one trial is 18%.
Answers
Answer:
To find the probability of no more than 2 successes in 5 trials of a binomial experiment in which the probability of success in any one trial is 18%, we can use the formula for the probability mass function of the binomial distribution:
P(X = k) = (n choose k) * p^k * (1 - p)^(n-k)
Where:
X is the number of successes in the binomial experiment
n is the number of trials
p is the probability of success in any one trial
k is the number of successes we are interested in
So, in this case, we want to find the probability of X being equal to 0, 1, or 2 successes. We can do this by summing the probabilities of each of these events:
P(X = 0) + P(X = 1) + P(X = 2)
Plugging in the values from the problem, we get:
P(X = 0) = (5 choose 0) * (0.18)^0 * (1 - 0.18)^(5-0) = 0.3199
P(X = 1) = (5 choose 1) * (0.18)^1 * (1 - 0.18)^(5-1) = 0.4199
P(X = 2) = (5 choose 2) * (0.18)^2 * (1 - 0.18)^(5-2) = 0.2082
So the probability of no more than 2 successes in 5 trials of a binomial experiment in which the probability of success in any one trial is 18% is:
0.3199 + 0.4199 + 0.2082 = 0.948

In 2015, the average distance from Earth to the moon was about 3.74 x 105 km. The distance from Earth to Mars was about 9.25 x 107 km. How much farther is traveling from Earth to Mars than from Earth to the moon? Write your answer in scientific notation.
Answers
Traveling from Earth to Mars is approximately 9.249626 x 10^7 km farther than traveling from Earth to the moon.
Earth to Mars is compared to traveling from Earth to the moon, we need to calculate the difference between the distances.
The distance from Earth to the moon is approximately 3.74 x 10^5 km.
The distance from Earth to Mars is approximately 9.25 x 10^7 km.
To find the difference, we subtract the distance to the moon from the distance to Mars:
9.25 x 10^7 km - 3.74 x 10^5 km
To subtract these numbers, we need to make sure the exponents are the same. We can rewrite the distance to the moon in scientific notation with the same exponent as the distance to Mars:
3.74 x 10^5 km = 0.374 x 10^6 km (since 0.374 = 3.74 x 10^5 / 10^6)
Now we can perform the subtraction:
9.25 x 10^7 km - 0.374 x 10^6 km = 9.25 x 10^7 km - 0.374 x 10^6 km
To subtract, we subtract the coefficients and keep the same exponent:
9.25 x 10^7 km - 0.374 x 10^6 km = 9.25 x 10^7 - 0.374 x 10^6 km
Simplifying the subtraction:
9.25 x 10^7 - 0.374 x 10^6 km = 9.249626 x 10^7 km
Therefore, traveling from Earth to Mars is approximately 9.249626 x 10^7 km farther than traveling from Earth to the moon.
Scientific notation is a convenient way to express very large or very small numbers. It consists of a coefficient (a number between 1 and 10) multiplied by a power of 10 (exponent). It allows us to write and manipulate such numbers in a compact and standardized form.
