to simplify the fraction just divide the numerator by the denominator;
35 ÷ 6 = 5 5/6 as a mixed number.
Answer:
Number 14 is a function and Number 16 is NOT a function.
Step-by-step explanation:
To check if a set of numbers form a function, you can look at the x values or the imput values.
For number 14 the x values are : 4,-3,-4,5,6. When looking at these values, there can only be one of each number.
For example in number 16, there's two 0's and we cannot allow that! So therefore, number 16 is not a function.
Also note, the y values are called the outputs.
A function is only allowed to have ONE imput with each output.
Hope this helps! :)
Answer:
<em>The height of the building is 21.38 m</em>
Step-by-step explanation:
<u>Trigonometric Ratios</u>
The ratios of the sides of a right triangle are called trigonometric ratios.
The image attached shows the measures and angles provided in the problem. The first angle of elevation is y=22°, the man walks B=20 m and finds the new angle of elevation is x=33°.
It's required to find the height of the building H.
The tangent ratio relates the opposite side with the adjacent side of a given angle. Applying it to the larger triangle:
Multiplying by D+B:
Dividing by tan 22°
Subtracting B:
Applying to the smaller triangle:
Multiplying by D:
Substituting from [1]:
Substituting values:
Operating:
H = 21.38 m
The height of the building is 21.38 m
To calculate the circumference,the equation is : 2丌r
Thus,the equation of the above would be
2丌(1)
=2丌
2丌 should be the answer,however if you cannot type that,try the ones below:
If you are to find a value,we generally use 3.14 or 7/22 for 丌
therefore the answer could be 6.28 or 7/11 as well.
Hope it helps!
