Please help I don't understand Pythagorean theorem

Mathematics
1 answer:
Karolina [17]3 years ago

So the Pythagorean Theorem is a²+b²=c² pretty much all you do is plug in what you know. So for number 3 you would plug in the numbers that you know into the formula. 
20²+b²=25²
BD isn't needed in the formula because it's not apart of the legnth we are looking at so you dont need to worry about that. 
Now do what the formula says.. 
400+b²=625
then you would subtract
625-400= 225
and "un-square" the answer by finding the square root 
√225 = 15 
AB= 15
you can always check your answer 
20²+15²=25²
400+225=625

Which of the following is true of the data represented by the box plot
zmey [24]

Answer:

The data is skewed to the bottom and contains an outlier.  

Step-by-step explanation:

1. Test for outlier

An outlier is a point that is more than 1.5IQR below Q1 or above Q3.  

IQR = Q3 - Q1 = 74 - 51 = 23

1.5 IQR  = 1.5 × 23 = 34.5

51 - 15 = 36 > 1.5IQR

The point at 15 is an outlier.

2. Test for normal distribution

The median is not in the middle of the box.  

Rather, it cuts the box into two unequal parts, so the data does not have a normal distribution.

3. Test for skewness

The longer part is to the left of the median, so the data is skewed left.

A ladder 10 ft long rests against a vertical wall. If the bottom of the ladder slides away from the wall at a rate of 1.1 ft/s,
pishuonlain [190]
 <span>let: 
X = the distance of the bottom of the ladder from the wall at any time 
dX/dt = rate of travel of the bottom of the ladder = 1.1 ft/sec 
A = the angle of the ladder with the ground at anytime 
dA/dt = rate of change of the angle in radians per second 

X = 10 cos A 

dX/dt= -10 sin A dA/dt = 1.1 

dA/dt = -1.1/(10 sinA) 

When X = 6; cosA = 6/10; sinA = 8/10 

Therefore: 

dA/dt = -1.1/(10 x 0.8) = -0.1375 radiant per second. </span>
