Answer:
$ 21
Step-by-step explanation:
Money spent = (2/5) * 60 + (1/4) * 60
= 2*12 + 1*15
= 24 + 15
= $ 39
Money save = 60 - 39 = $ 21
Answer:
40%.
Step-by-step explanation:
Write it as a fraction then multiply by 100:
(36/90) * 100
= 3600/90
= 40%.
Answer:
The graph of y=-3x^n is the reflection of the graph of y=3x^n about the x axis.
Step-by-step explanation:
If you graph these two functions, then you will notice that they look similar. for example the points of (1,-3) on graph y=-3x^n and point (-1,-3) on graph y=3x^n. They have the same y value but just the reflection of the x value. I hope this helped !!
I would try using Photomath or Desmos both great graphing apps!
Make a drawing of the situation:
Recalling the tangent trigonometric relationship, if the angle of inclination is A, then:
Use the inverse tangent function to find the value of A:
Use a calculator to find the numerical value of the inverse tangent of 6:
Therefore, the angle of inclination of the Sun is approximately 80.5°.
