To solve this problem, we can use the Law of Cosines. The Law of Cosines states that for a triangle with sides a, b, and c and the angle C opposite side c, the following equation holds:
c^2 = a^2 + b^2 - 2abcos(C)
In this problem, we are given the measure of angle C and the lengths of sides b and c. We can use this information to find the length of side a and the measures of angles A and B.
First, we can use the Law of Cosines to find the length of side a. Plugging in the given values, we get:
a^2 = c^2 - b^2 + 2bc cos(C)
Substituting in the given values, we get:
a^2 = 151^2 - 181^2 + 2 * 151 * 181 * cos(60.0°)
Solving this equation gives us a = 143 m.
Now that we have the length of side a, we can use the Law of Sines to find the measures of angles A and B. The Law of Sines states that for a triangle with sides a, b, and c and angles A, B, and C opposite these sides, the following equation holds:
a/sin(A) = b/sin(B) = c/sin(C)
We are given the lengths of sides a and b and the measure of angle C. We can use this information to find the measures of angles A and B.
First, we can use the Law of Sines to find the measure of angle A. Plugging in the given values, we get:
a/sin(A) = b/sin(B)
Solving for sin(A), we get:
sin(A) = a * sin(B) / b
Substituting in the given values, we get:
sin(A) = 143 m * sin(B) / 181 m
To find the measure of angle A, we can use the inverse sine function (sin^-1). This gives us:
A = sin^-1(sin(A))
= sin^-1(143 m * sin(B) / 181 m)
Similarly, we can use the Law of Sines to find the measure of angle B:
B = sin^-1(143 m * sin(A) / 181 m)
Since we have two unknowns (A and B) and two equations, there is a unique solution for this triangle.
Therefore, the number of solutions is 1, and the measures of angles A and B are A = 38.5° and B = 101.5°. The length of side a is 143 m.

what is modified Euler method?Modified Euler's method is a numerical method used to solve ordinary differential equations (ODEs). It is a variation of Euler's method that is more accurate than the original, but still relatively simple to implement. It works by taking a single iteration of the Euler method, then using the midpoint between the current and previous points to calculate the next point in the sequence. This is done in order to reduce the error.
Solution
We have, y(0) = 0
dy/dt = 1 – y
h = 0.1
Using modified Euler's method,
y(0.1) = y(0) + (1/2) h (f(t0, y0) + f(t0 + h, y0 + hf(t0, y0)))
= 0 + (1/2) (0.1) [(1 - 0) + (1 - 0 + 0.1)]
= 0.05
Similarly,
y(0.2) = 0.1 + (1/2) (0.1) [(1 - 0.05) + (1 - 0.1 + 0.1)]

The end behavior of the polynomial is, rises to the left and falls to the right.
What is end behavior of polynomial?
A polynomial function typically behaves at its end in the same way that its leading term, or the term with the largest exponent, does at its end.
Look at the leading term of the polynomial function to understand its end behavior. Given that the leading term has the highest power, its behavior will dominate the graph because it will grow much more quickly than the other terms as x gets very large or very small.
Consider, the given polynomial g(x) = x^2 (6 - x)
From the graph of the polynomial function we can see that the maximum point of the polynomial is at its vertex.
The vertex of the polynomial is (10, 90).
So this is the maximum value of the function is (10, 90).

b. Find the maximum height of the arrow.
The maximum height of the arrow is
feet.
c. How long does it take the arrow to hit the ground? Round your answer to the nearest second.

b) The maximum height if the arrow is; 198 feet
c) The time that it takes the arrow to hit the ground is; 16 seconds
How to write the quadratic equation in vertex form?We are given the function as;
y = -16t² + 112t + 2.
where;
y is the height (in feet) of an arrow
t is the time in seconds after it is shot from a bow
This is the equation of a vertical parabola open downward
The vertex is a maximum
The general form of a quadratic equation in vertex form is;
y = a(x - h)² + k²
where (h, k) is the vertex coordinate
a) y = -16t² + 112t + 2
This is in standard form and using completing the square, we can write in vertex form as;
y = -16(x - 3.5)² + 198
b) The vertex is the point (3.5, 198)
The maximum height of the arrow represents the y-coordinate of the vertex of the function
Thus, the maximum height of the arrow is 198 feet
c) We know that when the arrow hits the ground, the value of y is equal to zero. Thus, at y= 0, we have;
-16(x - 3.5)² + 198 = 0
Rearranging gives;
(x - 3.5)² = (198/16)
(x - 3.5) = ±√(198/16)
(x - 3.5) = ±12.375
x = 12.375 + 3.5
x = 15.875 ≈ 16 seconds which is the time it will take to hit the ground.

Answer:
y = [tex]\frac{3}{4}[/tex] x - 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + b ( m is the slope and c the y- intercept )
given
- 3x + 4y = 4 ( add 3x to both sides )
4y = 3x + 4 ( divide through by 4 )
y = [tex]\frac{3}{4}[/tex] x + 1 ← in slope- intercept form
with slope m = [tex]\frac{3}{4}[/tex]
• Parallel lines have equal slopes , then

A machine is designed to dispense 20 mg of d-desoxyephedrine into each capsule of a medicine. 13
pills are tested, and it's found that they have a mean drug content of 20.2 mg, with a standard
deviation of 2.4 mg. To a 1% level of significance, can it be asserted that the standard deviation of
the process (in general) is over 2 mg?
[Assume that the drug contents of all the pills are normally distributed.]
Answer: To answer this question, we need to perform a hypothesis test. The null hypothesis is that the standard deviation of the process is 2 mg or less, and the alternative hypothesis is that the standard deviation of the process is over 2 mg.
To test this hypothesis, we need to calculate the test statistic, which is the z-score. The z-score tells us how many standard deviations a given data point is from the mean. In this case, the z-score is calculated by subtracting the mean of the sample from the hypothesized mean of the population, and dividing that difference by the standard deviation of the sample:
z = (20.2 - 20) / 2.4 = 0.1
Since the z-score is positive, we know that the mean of the sample is greater than the hypothesized mean of the population. However, we need to compare this z-score to the critical value to determine whether it is statistically significant.
The critical value is the z-score that marks the cutoff between the region of acceptance and the region of rejection of the null hypothesis. For a 1% level of significance, the critical value is the z-score that marks the 99th percentile of the normal distribution. Since the normal distribution is symmetrical, this means that the critical value is 2.58 standard deviations from the mean.
Since the z-score we calculated is less than the critical value, we cannot reject the null hypothesis. This means that we cannot assert that the standard deviation of the process is over 2 mg at a 1% level of significance.

write an equation for the money they collect,y,as a function of the number of t-shirts they sell,x.
Answer:
Step-by-step explanation:
There are several ways to write an equation for the money collected as a function of the number of t-shirts sold. One possible equation is $y = x \cdot p$, where $p$ is the price of each t-shirt. This equation says that the total amount of money collected is equal to the number of t-shirts sold multiplied by the price of each t-shirt.Another possible equation is $y = p \cdot (x - c)$, where $c$ is the cost of producing each t-shirt. This equation says that the total amount of money collected is equal to the price of each t-shirt multiplied by the number of t-shirts sold minus the cost of producing each t-shirt.These are just two examples of how to write an equation for the money collected as a function of the number of t-shirts sold. The exact equation will depend on the specific details of the situation.

The final cost of a skateboard after all the discounts and reductions is $53.775.
Given that, during a clearance sale at a sporting goods store, skateboards were marked down 30%. On Saturday, an additional 25% was taken off already reduced prices of skateboards.
We need to find the final price after all discounts had been taken.
What is the discount?
The basic way to calculate a discount is to multiply the original price by the decimal form of the given percentage rate. To calculate the sale price of any item, we need to subtract the discount from the original price.
Given, that the original cost of the skateboard is $119.50.
Now, 30+25=55
So, the total decrease in percentage is 55%.
The final cost of a skateboard=119.50-55% of 119.50
=119.50-0.55 × 119.50
=119.50-65.725

A hypothesis test is used to test a claim. On a right-tailed hypothesis test with a 1.6257 critical value, the collected sample's test statistic is calculated to be 1.3994. Which of the following is the correct decision statement for the test?
a. Claim the null hypothesis is true
b. Claim the alternative hypothesis is true
c. Reject the null hypothesis
d. Fail to reject the null hypothesis
The correct part is (d) i.e. Fail to reject the null hypothesis.
What is hypothesis testing?
By evaluating whether or not the observed test statistic is more extreme than would be anticipated if the null hypothesis were true, the critical value approach determines whether something is "likely" or "unlikely." This means that the alternative hypothesis is accepted in place of the null hypothesis when the observed test statistic is more extreme than a cutoff number, known as the "critical value." The null hypothesis is not disproved if the test statistic does not deviate significantly from the crucial value.
Here, The critical value is 1.6257 and the sample's test statistic value is 1.3994.
We can see that the sample's test statistic value is not extreme as the critical value, So the null hypothesis should not be rejected.
Hence, It fails to reject the null hypothesis.

Adult tickets to the fall play cost $8 and student tickets cost $4. The drama class sold 20 more adult tickets than student tickets to the fall play. If
the class collected $880 from ticket sales, how many adult tickets were sold?
The drama class sold
adult tickets.
The solution is
Answer: 110
Step-by-step explanation: If the drama class sold 20 more adult tickets than student tickets to the fall play, and adult tickets cost $8, then the number of adult tickets sold can be calculated by adding 20 to the number of student tickets sold and multiplying by $8. We can set up an equation to represent this relationship, where A represents the number of adult tickets sold and S represents the number of student tickets sold:
A = S + 20
A * 8 = $880
We know that the total amount collected from ticket sales was $880, and we know that adult tickets cost $8, so we can divide $880 by $8 to find the number of adult tickets sold:
A = $880 / $8
A = 110
Therefore, the drama class sold 110 adult tickets to the fall play.

What is a linear equation?An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation forms a straight line.
A linear equation can have one or two variables. For example 5 = y+ 3y is an example of linear equation with one variable and y = 5 +3x is an example of linear equation with two variables.
8x-4= 2(4x+1)-6
8x-4= 8x+2-6
8x-4= 8x-4
Therefore the error is made where the parentheses is been solved, 2 is to multiply both 4x and 1.
