Answer:
Sin, Cos, Tan and others are used to calculate the ratios of the sides of a right angled triangle by taking a certain angle as the angle of reference.
On the other hand, Sin‐¹, Cos‐¹ and Tan-¹ are used to find the reference angle used to calculate the ratio of sides.
For this question,
we need to find which option should used to calculate the angle the slide makes with the vertical support.
So the option will have to be either A, C or E.
here, the base is 2.81m and hypotenuse is 3.64m.
we know, Cos = base / hypotenuse
So the angle is given by Cos-¹(2.81/3.64)
Option C
Answer:
Step-by-step explanation:
Use the attached given data to make a scatter plote. The diagram attached will aid you to do the plot.
please note you will have to merge each figure against each other.
<u>Step 1</u>
when number of quartz is = 1 , Price per quartz = 2. This will be merge against each other.
This step will be repeated for the remaining figure.
<u>Conclusion</u>
Since its a scatter plot we are not expecting a staright line graph.
Answer: No.
Step-by-step explanation: Sub -1/2 in for u in the equation:
8(-1/2) - 1 =6(-1/2)
=-4-1 = -3
=
-5=-3 which is false, so it is not a solution
Answer:
0.1056
Step-by-step explanation:
okay so using a table of standard normal probabilities:
1.) look for 1.2 on the left column and .05 (which will give you .8944)
2.) this will give you the area before it so do
1- 0.8944
3.) You have your answer!
