<u>4 less than n is -15</u>
<u>four is less than -15</u>
4<15
Since we need an angle measure we have to use an inverse trig ratio, sin^-1, cos^-1, or tan^-1.
Setting up the right triangle we have the opposite and adjacent so we use tan.
tan angle = 28/32
tan^-1 (28/32) = 41 degrees
Answer:
Investment with interest rate 0.1872 is better
Step-by-step explanation:
Given as :
George investment principal = $20,000
The Rate of interest (R1) = 18 % = %
I.e R1 = 18.67 %
Again The The Rate of interest (R2) = 0.1872 = 18.72 %
Let the time period for both rate of interest = 1 years
Now from compound interest method
Amount = Principal ×
Or, A 1 = $ 20 , 000 ×
Or, A 1 = $ 20 ,000 × 1.1867
∴ A 1 = $ 23,734
And A 2 = $ 20 , 000 ×
Or, A 2 = $ 20 ,000 × 1.1872
∴ A 2 = $ 23,744
Hence From the calculation of both amount it is clear that , investment with interest rate 0.1872 is better . Answer
Answer:
Step-by-step explanation:
Use trigonometry
<u>Let the height of the cloud be x, then we have:</u>
- tan 35° = x/525
- x = 525 tan 35°
- x = 367.6 (rounded)
The height of the cloud layer is 367.6 m
Answer:
- 22.5
Step-by-step explanation:
Answer:
90 decreased by 25% = 67.5
Absolute change (actual difference):
67.5 - 90 = - 22.5
