Answer:
x= 31.0°
Step-by-step explanation:
for this you have to use SohCahToa
as 9cm is opposite the x° this makes the 9cm the opposite
the longer side is always the hypotenuse but we don't need to worry about that side in this case
this means that the 15cm is the adjacent
from the SohCahToa we can find out whether we use sin, cos or tan
the sides we have are a (adjacent) and o ( opposite)
this means we use tan
as we are finding an angle we use tan^-1
tan^1(9/15)=30.96375653
so our angle is 31.0°
If the perimeter of a square is 280 feet, how long is each side of the square?
The length of each side of the square is 280/4 = 70 feet.
The perimeter of a square is the total length of all the sides of the square added together. Since the perimeter of this square is 280 feet, this means that if we add up the length of all four sides, the total length is 280 feet. Therefore, we can divide the perimeter (280 feet) by the number of sides (4) in order to calculate the length of each side. This means that the length of each side of the square is 280/4 = 70 feet. Therefore, the length of each side of the square is 70 feet. By dividing the perimeter of the square by the number of sides, we can easily calculate the length of each side of the square.

The function y = f(x) is graphed below. What is the average rate of change of the
function f(x) on the interval -6 ≤ x ≤-3?
Answer:
- 5
Step-by-step explanation:
the average rate of change of f(x) in the closed interval [ a, b ] is
\(\frac{f(b)-f(a)}{b-a}\)
here [ a, b ] = [ - 6, - 3 ] , then
f(b) = f(- 3) = - 15 ← point (- 3, - 15 ) from graph
f(a) = f(- 6) = 0 ← point (- 6, 0 ) from graph
then
average rate of change = \(\frac{-15-0}{-3-(-6)}\) = \(\frac{-15}{-3+6}\) = \(\frac{-15}{3}\) = - 5

Explanation:
Select any two points from the diagonal line. I'll pick (0,-10) and (2,-4).
Use these points in the slope formula
m = (y2 - y1)/(x2 - x1)
m = (-4 - (-10))/(2 - 0)
m = (-4 + 10)/(2 - 0)
m = 6/2
m = 3
The slope is 3.
The y intercept is b = -10 since this is the location where the diagonal line crosses the vertical y axis.
The values m = 3 and b = -10 have us go from y = mx+b to y = 3x-10

what is the result of 2.130 x 10³ - 6.6 x 10² =
Answer:
The answer you're looking for is 1470.
Step-by-step explanation:
The method I used was PEMDAS
Since there was no parenthesis, I simplified the exponents.
2.130 x 10³ - 6.6 x 10² = ?
2.130 x 1000 - 6.6 x 100 = ?
After that, I multiplied all terms next to each other.
2.130 x 1000 - 6.6 x 100 = ?
2130 - 660 = ?
The final step I did was to subtract the two final terms and ended up with 1470 as my final answer.

Given a collection of 2023 closed squares of total area 4, prove that they can be arranged to cover a unit square (overlaps are allowed)
We can arrange the 2023 squares to cover the unit square, with overlaps allowed.
We can prove that a collection of 2023 closed squares of total area 4 can be arranged to cover a unit square by using the pigeonhole principle. Since the total area of the squares is 4, the average area of each square is 4/2023. Let's take a unit square and divide it into 2023 smaller squares of area (1/2023) each. By the pigeonhole principle, we can assign one of the 2023 squares to each of the smaller squares. Since the average area of each square is 4/2023, each of the assigned squares will overlap with at most 4 other squares. Therefore, we can arrange the 2023 squares to cover the unit square, with overlaps allowed.

b. 6y + 4x units
c. 5x units
d. 16x + 12 units
The area of the square is 9x² units²
How to find the area and perimeter of a figure?The perimeter of a shape is defined as the total length of its boundary. In other words, the perimeter of a shape is the sum of the whole sides of the figure.
Therefore, let's find the perimeter of the shapes as follows:
a.
perimeter = x + 9 + x + 9 + x + x
perimeter = 4x + 18
b.
perimeter = 3y + 3y + 2x + 2x
perimeter = 6y + 4x
c.
perimeter = 2x + 2x + x
perimeter = 5x
d.
perimeter = 4x + 1 + 2x + 3x + 5 + 2x + 1 + 3x + 5 - 2x + 4x + 1 - (2x + 1)
perimeter = 16x + 12

statistical power is a measure of the ability to reject the null hypothesis when:
Statistical power is a measure of the ability to reject the null hypothesis when it is false. It represents the probability of correctly identifying a true effect or relationship in a statistical hypothesis test.
A high statistical power indicates a greater likelihood of detecting a significant result if the null hypothesis is indeed incorrect. The power of a statistical test depends on several factors, including the sample size, the effect size (the magnitude of the true effect or difference), the chosen significance level (often denoted as α), and the variability or noise in the data. Increasing the sample size or effect size generally increases the statistical power, while a lower significance level or higher variability decreases it.
Power analysis is commonly used to determine an appropriate sample size for a study, ensuring that it is adequately powered to detect the desired effect. A higher power is desirable as it reduces the chances of a Type II error (failing to reject the null hypothesis when it is false) and increases the chances of correctly detecting real effects or relationships.

Step-by-step explanation:
The solution of the systems of equations in the graph is 'the point of intersection'
The point of intersection is the point at which two lines meet or intersect.
For this graph, the point of intersection is the point where the the red and blue graph meet. The x and y values (or coordinates) have to be read from the graph.
From the graph:
x = 2
y = \(-1\)
Together these x and y values form an ordered pair

there are two important properties of probabilities. 1) individual probabilities will always have values between and . 2) the sum of the probabilities of all individual outcomes must equal to .
1.) Probabilities range from 0 to 1, denoting impossibility and certainty, respectively.
2.) The sum of probabilities of all possible outcomes is equal to 1.
1.) Individual probabilities will always have values between 0 and 1. This property is known as the "probability bound." Probability is a measure of uncertainty or likelihood, and it is represented as a value between 0 and 1, inclusive.
A probability of 0 indicates impossibility or no chance of an event occurring, while a probability of 1 represents certainty or a guaranteed outcome.
Any probability value between 0 and 1 signifies varying degrees of likelihood, with values closer to 0 indicating lower chances and values closer to 1 indicating higher chances. In simple terms, probabilities cannot be negative or greater than 1.
2.) The sum of the probabilities of all individual outcomes must equal 1. This principle is known as the "probability mass" or the "law of total probability." When considering a set of mutually exclusive and exhaustive events, the sum of their individual probabilities must add up to 1.
Mutually exclusive events are events that cannot occur simultaneously, while exhaustive events are events that cover all possible outcomes. This property ensures that the total probability accounts for all possible outcomes and leaves no room for uncertainty or unaccounted possibilities.

Find the time. Round to the nearest month given the following:Principal: $3,500Rate: 8.25%Interest: $143.50
In order to find the time required, we can use the formula below for compound interest:
\(I=P(1+r)^t-P\)Where I is the interest, P is the principal, r is the rate and t is the time.
So, for I = 143.5, P = 3500 and r = 0.0825, we have:
\(\begin{gathered} 143.5=3500(1+0.0825)^t-3500 \\ 143.5+3500=3500(1.0825)^t \\ 3643.5=3500(1.0825)^t \\ 1.0825^t=\frac{3643.5}{3500} \\ 1.0825^t=1.041 \\ \ln (1.0825)^t=\ln (1.041)_{} \\ t\cdot\ln (1.0825)=\ln (1.041) \\ t=\frac{\ln (1.041)}{\ln (1.0825)} \\ t=\frac{0.0401818}{0.07927318} \\ t=0.5 \end{gathered}\)Therefore it will take 0.5 years to achieve this interest.

30 POINTS! Find an explicit formula for the geometric sequence −1,−7,−49,−343
d(n)=
Answer:
\(d(n) = { - 7}^{n - 1} \)Step-by-step explanation:
Since the sequence above is a geometric sequence
For an nth term in a geometric sequence
\(d(n) = a ({r})^{n - 1} \)where
a is the first term
r is the common ratio
n is the nth term
To find the common ratio divide the previous term by the next term
That's
\(r = \frac{ - 7}{ - 1} = 7 \: \: \: \: or \\ r = \frac{ - 49}{ - 7} = 7 \: \: \: or \\ r = \frac{ - 343}{ - 49} = 7\)So the common ratio / r = 7
the first term is - 1
Substitute the values into the above formula
\(d(n) = - 1( {7})^{n - 1} \\ \)We have the final answer as
\(d(n) = { - 7}^{n - 1} \)Hope this helps you
