A right triangle has a leg length of 12 and a hypotenuse length of 18. What is the length of the other leg?
lord [1]

Answer:

The length of the leg is 13.416

Step-by-step explanation:

To calculate one side of a right triangle from the other 2 sides we have to use Pythagoras

h = hypotenuse  = 18

a = leg 1 = 12

b = leg 2 =

h² = a² + b²

we replace the known values  and solve

18² = (12)² + (a)²

324 = 144 + (a)²

324 - 144 = (a)²

324 - 144 = (a)²

√180 = a

13.416 = a

The length of the leg is 13.416

The time taken to prepare the envelopes to mail a weekly report to all executives in a company has a normal distribution, with a
telo118 [61]

Answer:

Mailing preparation takes 38.29 min max time to prepare the mails.

Step-by-step explanation:

Given:

Mean:35 min

standard deviation:2 min

and 95%  confidence interval.

To Find:

In normal distribution mailing preparation time  taken less than.

i.eP(t<x)=?

Solution:

Here t -time and x -required time

mean time 35 min

5 % will not have true mean value . with 95 % confidence.

Question is asked as ,preparation takes less than  time means what is max time that preparation will take to prepare mails.

No mail take more time than that time .

by Z-score or by confidence interval is

Z=(X-mean)/standard deviation.

Z=1.96 at  95 % confidence interval.

1.96=(X-35)/2

3.92=(x-35)

X=38.29 min

or

Confidence interval =35±Z*standard deviation

=35±1.96*2

=35±3.92

=38.29 or 31.71 min

But we require the max time i.e 38.29 min

And by observation we can also conclude the max time from options as 38.29 min.

Find the amplitude and the equation of the midline of the periodic function.
Masja [62]

Answer:

Option B. Amplitude =3 midline is y =2.

Step-by-step explanation:

In the graph attached we have to find the amplitude and midline of the periodic function.

Amplitude of the periodic function = (Distance between two extreme points on y asxis)/2

=  (5-(-1))/2 = (5+1)/2 =6/2 =3.

Since amplitude of this function is 3 and by definition amplitude of any periodic function is the distance between the midline and the extreme point of wave on one side.

Therefore midline of the wave function is y=2 from which measurement of the amplitude is 3.

How is the additive inverse property used to subtract rational numbers? Use the property to solve the following: (-2) - 4 = 5 -
Vika [28.1K]
The additive inverse of a number is what you can add to that number for the sum to be zero. For real numbers, such as rational numbers, that means the additive inverse can be found by just flipping the sign of the number.

The additive inverse property says if you add a number and its additive inverse, then the sum is zero.
 
For example, let's use the number 3. The additive inverse of 3 is -3, since 3 + (-3) = 0. This is also true the other way around. The additive inverse of -3 is 3.

When subtracting rational numbers, remember that subtracting is the same as adding a negative! That means 3 - 3 is the same as 3 + (-3) or -3 - (-3) is the same as -3 + 3. Both of these sums involve a number and its additive inverse and they add up to zero.

For the problem, I don't think you gave me the complete problem, or perhaps there's a typo? Let me know and then I can edit my response to help you out :)
