\(2\sin{\theta} = -\sqrt{2}\)
We must isolate the desired variable, hence:
\(\sin{\theta} = -\frac{\sqrt{2}}{2}\)
Then we must apply the arcsine function, which is the inverse cosine, hence:

Step-by-step explanation:
Find the diagram to the question attached. Two congruent triangles has all its sides to be equal. This means that the sides of ΔABM will be equal to that of ΔDCM (SSS rule).

a car is driving at 100 kilometers per hour. how far, in meters, does it travel in 2 seconds? meters
Answers
A car travels 500/3 meters in 2 seconds.
What is speed?
The speed at which an object's location changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined. Given that it just has a direction and no magnitude, speed is a scalar number.
Here, we have
Speed of car = 100 KM/ hour
1 km= 1000m
1 hour = 3600 seconds
Let's find the speed of the car in Meters/second
Speed of car in m/sec = 100*1000 m/3600 second
Here we have taken 1000 for km and 3600 for an hour
Speed of car in m/sec = 100*1000 m/3600 second = 500/18 m/second
Speed of car in m/sec = 250/9 m per sec
We know that
Distance = speed*time
Speed = 250/9 m per sec
Time = 2 second
Distance = 250/9 * 2 meters = 500/3 meters
Hence, a car travels 500/3 meters in 2 seconds.

On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the way. Which decimal number shows the portion of the distance Sandy skips?
Answers
Answer:
0.2
Step-by-step explanation:
Convert the walking to percent
\(\frac{1}{2} \times 100 = 50\)
Add both skateboarding and walking
\(30\% + 50\%\\\\= 30 + 50\\\\= 80\)
Now, subtract that from a whole percent
\(100 - 80 = 20\\\\20\%\)
Convert it to a decimal
\(20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2\)
Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.

Step-by-step explanation:
they are similar, that means for our case here that they're is one central scaling factor for all sides between the 2 triangles.
by looking at the forms of both triangles, we see that
ET corresponds to TR.
FT corresponds to TS.
FE corresponds to RS.
for TE and TR we have the length information :
25 and 40
so, the scaling factor between these 2 corresponding sides can then be used for the other pairs of corresponding sides.
the scaling factor to go from the large to the small triangle is
25/40 = 5/8
therefore,
FT = TS × 5/8 = 22 × 5/8 = 11×5/4 = 55/4 = 13.75
FE = RS × 5/8 = 54 × 5/8 = 27×5/4 = 33.75
the perimeter of TFE is therefore
25 + 13.75 + 33.75 = 72.5

Answers
The false statement is: "The researchers would come to the conclusion that the programme was successful if they used a significance level of 1%."
What is significance level?
A significance level, denoted by α, is the threshold chosen by researchers to determine the level of evidence required to reject the null hypothesis. It represents the maximum acceptable probability of making a Type I error (incorrectly rejecting the null hypothesis when it is true).
In this case, the given p-value is 0.003. If the null hypothesis is true, the p-value represents the likelihood of obtaining a test statistic that is equally extreme to or more extreme than the one that was observed. It offers proof that the null hypothesis is false.
We can conclude that there is strong evidence to reject the null hypothesis in favour of the alternative hypothesis because the p-value is 0.003, which is lower than any often used significance level like 0.05 or 0.01. Thus, if the researchers apply a 5% level of significance, they would draw the conclusion that the programme was successful.
However, if the researchers use a significance level of 1%, they would require even stronger evidence to reject the null hypothesis. Since the p-value of 0.003 is greater than 0.01, they would not be able to reject the null hypothesis at the 1% significance level and would not conclude that the program was effective.

Draw a rectangle that is 8 squares long and 1 2 of a square wide. Then add up the partial squares to find the area. Multiply to check your answer. (i got it wrong, and my teacher told me to redo it so may someone help me?-)
Answers
Answer:
To draw a rectangle that is 8 squares long and 12 squares wide, you can draw a rectangle with 8 squares in one row and 12 squares in each column.
To find the area of the rectangle, you can count the number of squares in the rectangle. In this case, there are 8 rows and 12 columns, so the area of the rectangle is:
8 x 12 = 96
Therefore, the area of the rectangle is 96 square units.
To check your answer, you can multiply the length and width of the rectangle. The length is 8 and the width is 12, so:
8 x 12 = 96
As you can see, this is the same answer we got by counting the squares, so our answer is correct.
give the equation of a line that goes through the point ( 27 , 2 ) and is perpendicular to the line − 9 x 2 y
Answers
The equation of a line that passes through the point (27, 2) and is perpendicular to the line -9x + 2y = 0 can be found using the properties of perpendicular lines. The equation is -9x + 2y = 0 is y - 2 = (-2/9)x + 6.
To obtain the equation, we need to determine the slope of the given line and then find the negative reciprocal of that slope. The negative reciprocal of a slope is a property of perpendicular lines. Once we have the new slope, we can substitute it into the point-slope form of a linear equation.The given line has the equation -9x + 2y = 0. To find its slope, we can rearrange the equation in the slope-intercept form (y = mx + b), where m represents the slope. By isolating y, we have 2y = 9x, which simplifies to y = (9/2)x. Comparing this equation with y = mx + b, we can see that the slope of the given line is m = 9/2.
To find the negative reciprocal of this slope, we take the reciprocal of 9/2 (which is 2/9) and then negate it (change the sign). Therefore, the slope of the perpendicular line is -2/9.Now that we have the slope (-2/9) and the point (27, 2), we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1). Plugging in the values, we get y - 2 = (-2/9)(x - 27). Simplifying this equation gives us the final result: y - 2 = (-2/9)x + 6.
The equation of the line that passes through the point (27, 2) and is perpendicular to the line -9x + 2y = 0 is y - 2 = (-2/9)x + 6. This equation was obtained by finding the negative reciprocal of the slope of the given line and using point-slope form of a linear equation.
