Answer:
sin 60° = 0.9
Step-by-step explanation:
sin 60° = cos 30°
cos 30° = 0.866025403
0.866025403 to one significant figure
0.866025403 ~ 0.9
~. means approximately.
therefore sin 60° = cos 30°
sin 60° = 0.9
Answer:
4 hours
Step-by-step explanation:
y= 40x +225
$385 money to spend - $225 that go for hard drive = $160
40* x can be maximum 160 so x= 160 /40= 4
The range of the exponential function f(x) = 2.7ˣ will be from zero to infinity that is (0, ∞).
<h3>What are domain and range?</h3>
The domain means all the possible values of x and the range means all the possible values of y.
The exponential function is given below.
f(x) = 2.7ˣ
We know the value of the exponential function is always positive.
Then the range of the exponential function f(x) = 2.7ˣ will be from zero to infinity that is (0, ∞).
More about the domain and range link is given below.
