Answer:
Question 1:
cos a = 0.2195
tan a = 4.445
Question 2:
sin a = 0.8
tan a = 1.333
Step-by-step explanation:
<h3 /><h3>Question 1:</h3>
Given that;
sin a = 40/41
a = sin ⁻¹ (40/41)
a = 77.32°
Now we have to find the value of cos a and tan a:
a = 77.32°
cos 77.32° = 0.2195
tan 77.32° = 4.445
<h3>Question 2:</h3>
Given that;
cos a = 0.6
a = cos ⁻¹ (0.6)
a = 53.13°
Now we have to find the value of cos a and tan a:
a = 53.13°
sin 53.13° = 0.8
tan 53.13° = 1.333
Answer:
240 km.
Step-by-step explanation:
The car travels 200km per hour. so multiply it by 1.2 and you get 240km.
I don’t understand this can you explain please
With this inverse functiion, you would want to replace f(x) with y for now.
so new equation
y = 1/4^x - 12
then change positions of y and x
x = 1/4^y - 12
Then try to get Y by itself
x + 12 = 1/4^y
So then use Logarithm
Log Base_ 1/4 _ (x+12) = y
It would be B. -6.
f(x) = 3x-12
f(2) = 3(2)-12
f(2) = 6-12
f(2) = -6
