Answersadfs:
Domain of the exponential function is (-∞, ∞)
the range is (0, ∞)
Stasdfep-by-step explanation:
Domain is the set of x values for which the function is defined. there is no restriction for x in exponential function.
Domain of the exponential function is (-∞, ∞)
Range is the set of y values for which the function is defined
For range, of we plug in positive or negative number for x the value of y is always positive because we have exponent x
Hence the range is (0, ∞)
Answer: The value of y is 39.6 when x = 11 and the required expression is y(11) = 39.6
Step-by-step explanation:
Since we have given that
y varies directly as x.
If y = 18, when x = 5.
So, we need to find the value of y when x is 11.
According to question, we get that
Hence, the value of y is 39.6 when x = 11 and the required expression is y(11) = 39.6
Answer:
23.6
Step-by-step explanation:
<u><em>Finding AC:</em></u>
Cos 61 =
0.48 × 10 = Adjacent
AC = 4.8
<u><em>Now, CB:</em></u>
Cos 29 =
0.87 × 10 = CB
CB = 8.8
<u><em>The perimeter:</em></u>
=> 10+4.8+8.8
=> 23.6
