Answers
Answer:
b) y = -2/3 + 1
Step-by-step explanation:
The format for the equation is y = mx + b
(m is the slope, and b is the y intercept)
Slope is rise over run (the units the line moves up and the units the line moves to the right)
In this case, the slope is: -2/3 because it goes down 2 and to the right 3.
The y intercept is 1.
This makes our equation:
y = -2/3 + 1

A.f(x)=(0.5)^x
B.f(x)=5*x
C.f(x)=(1/15)^x
D.f(x)=(1/5)^x
Answers
The answer will be f(x) = 5*. If f′(x)>0 on an open interval, then f is increasing on the interval and If f′(x)<0 on an open interval, then f is decreasing on the interval.
Which function is making f X larger?For a given function, y = F(x), the function is known as an increasing function if the value of y increases as the value of x increases, and the function is known as a decreasing function if the value of y decreases as the value of x increases.The order of the numbers is said to be growing if they are written from smallest to largest, but decreasing order is used when the numbers are written from largest to smallest.You must first compute the derivative, then make it equal to 0, and then determine which zero values the function is negative between in order to determine whether a function is decreasing. In order to determine when the function is negative and, consequently, decreasing, test values on all sides of these.Hence, The answer will be f(x) = 5*. If f′(x)>0 on an open interval, then f is increasing on the interval and If f′(x)<0 on an open interval, then f is decreasing on the interval.

Ms Chen wants to purchase Christmas lights to decorate her house. The lights cost 13$ and she saved 360$ dollars for the project. How many boxes can she buy
Answers
With the $360 she has saved, Ms. Chen is able to purchase 27 boxes of Holiday lights.
To determine how many boxes of Christmas lights Ms. Chen can buy, we need to divide the amount of money she has saved by the cost of each box of lights.
The cost of each box of lights is given as $13.
We can set up a division problem to find the number of boxes:
360 ÷ 13 = 27.69
Since we cannot buy a fraction of a box, we round down to the nearest whole number to get the maximum number of boxes Ms. Chen can buy:
27
Therefore, Ms. Chen can buy 27 boxes of Christmas lights with the $360 she has saved.

The inequality which is used to represent normal "temperature-range" for "human-body", is (d) |t − 98.6| ≤ 1.8.
The "average-temperature" of body is = 98.6° F, and it can vary by 1.8°F.
The inequality |t − 98.6| ≤ 1.8 indicates that the absolute difference between the body temperature and the average temperature is less than or equal to 1.8° F.
This means that the body temperature t can vary within a range of 1.8° F from the average temperature of 98.6° F.
Which means, the temperature cam range from :
⇒ 98.6-1.8 ≤ t ≤ 98.6+1.8,
⇒ 96.8 ≤ t ≤ 100.4;

The test statistic of zequalsnegative 3.25 is obtained when testing the claim that pequals3 divided by 5.
a. Using a significance level of alphaequals0.01, find the critical value(s).
b. Should we reject Upper H 0 or should we fail to reject Upper H 0?
Answers
a. Using a significance level of α = 0.01, the critical values for a two-tailed test are ±2.576.
b. To determine whether to reject or fail to reject the null hypothesis, we compare the test statistic (-3.25) to the critical values. Since -3.25 is less than -2.576, we can reject the null hypothesis at the 0.01 significance level. This means we have evidence to support the claim that p = 3/5.
What is significance level?
Significance level, denoted as alpha (α), is the probability threshold used to determine whether a statistical hypothesis is rejected or not. It represents the maximum level of Type I error that a researcher is willing to accept.
A test statistic is a numerical value calculated from a sample of data that is used in hypothesis testing to determine whether to reject or fail to reject a null hypothesis.
The test statistic is compared to a critical value to make this determination. The critical value is a threshold value determined by the level of significance and the degrees of freedom of the sample.
If the test statistic falls within the rejection region determined by the critical value, the null hypothesis is rejected. If the test statistic falls outside the rejection region, the null hypothesis is not rejected.
a. Using a significance level of α = 0.01, the critical values for a two-tailed test are ±2.576.
b. To determine whether to reject or fail to reject the null hypothesis, we compare the test statistic (-3.25) to the critical values. Since -3.25 is less than -2.576, we can reject the null hypothesis at the 0.01 significance level. This means we have evidence to support the claim that p = 3/5.

State the domain, the range, and the intervals on which function is increasing decreasing, or constant in interval notation. State the domain and range using interval notation.
Answers
Answer:
\(Domain = (-\infty, \infty)\)
\(Range = (-\infty, 4]\)
Increasing interval is: \((-\infty, 0)\)
Decreasing interval is: \((0, \infty)\)
Constant at no interval
Step-by-step explanation:
Given
See attachment for graph
Solving (a): The domain
From, the attached graph, we have:
\(y = -x^2 + 4\)
The degree of the polynomial (i.e 2) is even.
Hence, the domain is the set of all real numbers, i.e.
\(Domain = (-\infty, \infty)\)
Solving (b): The range
The curve of \(y = -x^2 + 4\) opens downward, and the maximum is:
\(y_{max} = 4\)
This means that the minimum is:
\(y_{mi n} = -\infty\)
Hence, the range of the set is:
\(Range = (-\infty, 4]\)
Solving (c): Interval where the function increases/decreases/constant
In (a), we have:
\(Domain = (-\infty, \infty)\)
Split to 2 (at vertex x = 0)
\((-\infty, 0)\) and \((0, \infty)\)
So:
The increasing interval is: \((-\infty, 0)\)
The decreasing interval is: \((0, \infty)\)
The function has a tangent at \(x = 0\) but at no interval, was the function constant

The area of the polygon JKLMNO is 68.5 square units
The area of triangle MNOThe coordinates of the triangle are:
M = (-1, -5)
N = (-8, -6)
O = (-5, -2)
Calculate the base and the height of the triangle using:
\(d = \sqrt{(y_2 -y_1)^2 +(x_2 -x_1)^2\)
So, we have:
\(ON = \sqrt{(-5+ 8)^2 +(-2 + 6)^2\)
ON = 5
\(OM = \sqrt{(-5+ 1)^2 +(-2 + 5)^2\)
OM = 5
The area is:
Area = 0.5 * ON * OM
This gives
Area = 0.5 * 5 * 5
Evaluate
Area = 12.5
Hence, the area of the triangle MNO is 12.5 square units

\(d = \sqrt{(y_2 -y_1)^2 +(x_2 -x_1)^2\)
So, we have:
\(OM = \sqrt{(-5+ 1)^2 +(-2 + 5)^2\)
OM = 5
\(ML = \sqrt{(-1 - 5)^2 + (-5 - 3)^2\)
ML = 10
The perimeter is:
Perimeter = 2 * (OM + ML)
This gives
Perimeter = 2 * (5 + 10)
Evaluate
Perimeter = 30
Hence, the perimeter of the rectangle JLMO is 30 units
The area of the polygonIn (a), we have:
The area of the triangle MNO is 12.5 square units

the largest number in the sequence is 23, and the correct option is (j) 23.
How to find?
The sum of a sequence of consecutive odd numbers, where the smallest term is 1, can be expressed as the square of the number of terms in the sequence. Let n be the number of terms in the sequence. Then the sum of the sequence is:
1 + 3 + 5 + ... + (2n - 1) = n²2
We are given that the sum of one of these sequences is 144, so we can solve for n:
n²2 = 144
n = 12
Therefore, the sequence has 12 terms. To find the largest number in the sequence, we can use the formula for the nth term of a sequence of consecutive odd numbers:
a_n = 2n - 1
Substituting n = 12, we get:
a_12 = 2(12) - 1 = 23
Therefore, the largest number in the sequence is 23, and the answer is (j) 23.

A standing wave can be mathematically expressed as y(x,t) = Asin(kx)sin(wt)
A = max transverse displacement (amplitude), k = wave number, w = angular frequency, t = time.
At time t=0, what is the displacement of the string y(x,0)?
Express your answer in terms of A, k, and other introduced quantities.
Answers
The mathematical expression y(x,t) = Asin(kx)sin(wt) provides a way to describe the behavior of a standing wave in terms of its amplitude, frequency, and location along the string.
At time t=0,
the standing wave can be mathematically expressed as
y(x,0) = Asin(kx)sin(w*0) = Asin(kx)sin(0) = 0.
This means that the displacement of the string is zero at time t=0.
However, it is important to note that this does not mean that the string is not moving at all. Rather, it means that the string is in a state of equilibrium at time t=0, with the maximum transverse displacement being A.
As time progresses, the standing wave will oscillate between the maximum positive and negative transverse displacement values, creating a pattern of nodes (points of zero displacements) and antinodes (points of maximum displacement).
The wave number k and angular frequency w are both constants that are dependent on the physical properties of the string and the conditions under which the wave is being produced.
