The values of the following are:
Sin A = 0.71
Cos A = 0.71
Sin B = 0.71
Cos B = 0.71
What are trigonometric identities?There are three commonly used trigonometric identities.

Tan x = 1/ cot x or sin x / cos x
Cot x = cos x / sin x
We have,
Right triangle ABC.
∠C = 90
The other two sides are a = 8 and b = 8
This means,
The angle opposite to the side a = 8 and b = 8 are equal.
Now,
∠A = ∠C
∠C + ∠A + ∠B = 180
90 + ∠A + ∠B = 180
2∠A = 180 - 90
∠A = 90/2
∠A = 45
∠B = 45
Now,
c² = a² + b²
c² = 64 + 64
c² = 128
c = √128

Assume that for dry rice and beans:

40 basins ≈ 1 sack
(a) A sack contains 100 kg of rice.
Estimate the number of kilograms of rice in 1 başin.
Estimate the number of grams of rice in 1 cup.
(b) A trader buys a sack of rice for 6 000 and sells it at 200 per basin.
Estimate the profit on a sack of rice.
(c) A trader charges #5 000 for a sack and 140 for a basin for beans.
Four women buy a sack of beans between them. They share the beans equally.
How many basins does each woman get?
How much does each woman save by buying the beans in this way?
(a) 1 sack of rice contains 100 kg of rice. If 1 basin of rice is equal to 20 cups, then 1 sack is equal to 40*20 = 800 cups.
Therefore, 1 basin of rice contains 100/40 = 2.5 kg of rice.
1 cup of rice contains 2.5/20 = 0.125 kg of rice.
(b) A trader buys a sack of rice for 6 000 and sells it at 200 per basin. If 1 sack contains 800 cups of rice, then the total revenue from a sack of rice is 800*200 = 160,000.
Therefore, the profit on a sack of rice is 160,000-6,000 = 154,000
(c) A trader charges #5 000 for a sack of beans and 140 for a basin. If four women buy a sack of beans between them, they share the beans equally, so each woman gets 1/4 of a sack of beans, which is equal to 1/440 = 10 basins of beans.
Each woman gets 10 basins of beans which cost 14010 = 1,400. If they had bought the beans individually at 140 per basin, they would have spent 140*10 = 1,400.

A group of researchers establish a p-value of 0.05 for their hypothesis test. What does this mean?
a. The probability of getting a significant result for the test is 5%.
b. There is 5% probability that a true null hypothesis will be rejected.
C. The chi-square critical value for their dataset is 0.05
d. Only measured values of 0.05 or greater will be included in the test.
Answer:
b
Step-by-step explanation:
b. There is 5% probability that a true null hypothesis will be rejected.
A p-value of 0.05 represents the probability of obtaining a test statistic as extreme or more extreme than the one observed under the assumption that the null hypothesis is true. In other words, it is the probability of observing the data or more extreme data assuming the null hypothesis is true. It is also the threshold level of significance beyond which the null hypothesis is rejected in favor of the alternative hypothesis. A p-value of 0.05 means that there is a 5% probability that the observed results occurred by chance under the null hypothesis and that there is a 95% probability that the observed results occurred due to a real effect.

The square root is eight times 18 and the squared root is six times six. It is the square to 36 over. It's eight times 18. There are 44 items.
The square to 36 is a question. I don't know what time it gives me. There were 36. 36 times six is 6. Six Over would be this. What time gives me 1 44?

A bottle of liquid laundry detergent priced at $16.99 for a 52-load bottle has been changed to $16.49 for a 48-load bottle. By what percentage has the price per load changed?
Answer:
5.1% increase
Step-by-step explanation:
You want the percentage change in price per load when the price of detergent went from $16.99 for 52 loads to $16.49 for 48 loads.
Percentage changeThe percentage change is given by the formula ...
((new price)/(old price) -1) × 100%
Price per loadThe price per load is found by dividing the price of the bottle of detergent by the number of loads it will wash.
old price per load = $16.99/52 ≈ $0.32673
new price per load = $16.49/48 ≈ $0.34354
ApplicationThen the percentage change is ...
(0.34354/0.32673 -1) × 100% ≈ 0.05145 × 100% ≈ 5.1%
The price per load has increased by about 5.1%.

Then use the orange line segments (square symbol) to plot the economy's short-run aggregate supply (AS) curve at each of the following price levels: 90, 95, 100, 105, and 110
The purple line would be plotted at the level of output $60 billion, and the orange line segments would be plotted at 90, 95, 100, 105, and 110 respectively.
1. Plot the purple line at the level of output $60 billion.
2. Plot the orange line segments at 90, 95, 100, 105, and 110 respectively.
The long-run aggregate supply (RAS) curve is used to represent the natural level of output for an economy. In this case, the natural level of output is $60 billion of real GDP with a price level of 100. Therefore, the purple line should be plotted at the level of output $60 billion on the graph. The short-run aggregate supply (AS) curve is used to show how the level of output reacts to the price level. Therefore, the orange line segments should be plotted at 90, 95, 100, 105, and 110 respectively. This will show how the level of output changes when the price level is different from the natural level. This will help to illustrate how the economy may react when the price level is different than expected.

What is a pentagon?A pentagon is a 2D polygon with five sides and five angles.
Pentagon is formed from three triangles, so the sum of angles in a pentagon = 3 × 180° = 540°.
We are given in the figure , following information about a pentagon:
3 angles are 90 degrees, one angle is (6x+1) degrees, and the other angle is (8x-11) degrees.
To solve for x, we need to add all of the angles together.
The sum of the angles in any polygon is always equal to (n-2)*180, where n is the number of sides in the polygon.
In this case, n=5, so the sum of the angles is (5-2)*180 = 540 degrees.
We can now solve for x by substituting our known values into the equation.
540 = 90 + (6x + 1) + (8x - 11)

y= –x+z
1. 16= –4+z
16+4=z
20=z
z=20
2. 15= –5+z
15+5=z
20=z
z=20
z=20 is true
Find the average rate of change if the function f(x)=7x from x1=0 to x2 =4
The average rate of change of the function f(x) = 7x from x1 = 0 to x2 = 4 is solved to be 7
How to solve for the rate of changeThe rate of change is solved using the formula
= change in y / change in x
In the problem, the function is f(x) = 7x from x1 = 0 to x2 = 4
hence y = f(x) =
For x = 0, y = 7 * 0 = 0
For x = 4, y = 7 * 4 = 28
rate of change
= 28 - 0 / 4 - 0
= 28 / 4
= 7
the rate of change is 7

A test plane flies in a straight line with positive velocity v(t), in miles per minute, at time t minutes, where v is a differentiable function of t. Selected values of v(t) are shown in the table below. t (minutes) 0 5 10 15 20 25 30 35 40
v (t) (miles per minute) 7.0 9.2 9.5 7.0 4.5 2.4 2.4 4.3 7.3 Based on the values in the table, what is the smallest number of instances at which the acceleration of the plane could equal zero on the open interval 0
our function v(t) is differentiable in the interval 0 to 40, by mean value theorem a(t)=0 at least two value of t. it can be t=0 and t=5, which is smallest.
A test plane files in a straight line with positive velocity v(t), v is a differentiable function of t.
selected value of v(t) for 0≤ t≤ 40are shown in the table.
We have to justify that what is that smallest number of instances at which the acceleration of plane could equal to zero on the interval (0,40).
We are aware about mean value theorem.
somewhere between t=0 , t=5, v'(t) =0
because v(t) is a differentiable function.
also, t=25 and t=30
v'(t)=0 because
[tex]\frac{v(30)-v(25)}{30-25} =0[/tex],
this means a(t) =0 for at least two value of t.
So, our function is differentiable in the interval 0 to 40, by mean value theorem a(t)=0 at least two value of t. it can be t=0 and t=5.

The exponential depreciation rate to the nearest tenth of a percent is -0.2%.
How to calculate the exponential depreciation rate?we need to use the exponential decay formula to find exponential rate.
A = A0 * e^(-rt)
where:
A0 = initial value of car (52,000)
A = final price of the car (45,000)
t = elapsed time (32 months)
r = exponential depreciation rate
Rearrange the formula to solve for the exponential depreciation rate "r".
r = -ln(A/A0) / t
Insert value:
r= -ln(45,000 / 52,000) / 32
r = -0.067115074/32
r = -0.002097288
The exponential depreciation rate, expressed as a percentage to the nearest tenth of a percent, is obtained by multiplying by 100.
r = -0.002097288 * 100
r = -0.21D
44 Therefore, the exponential depreciation rate to the nearest tenth of a percent is -0.2%.
