Answer:
Question 18
=$3.33
Step-by-step explanation:
i)
26/100 x 4.5
=1.17
(the discount price)
ii)
$4.5-$1.17
=$3.33
The sinusoid makes a complete oscillation (i.e. 360°) every 3 seconds. So, in one second it makes 1/3 of a turn, leading to 360°/3 = 120°.
So, the correct answer is the last one.
Answer:
The correct answer is f(x)
Step-by-step explanation:
The answer is f(x) because is the result of the quadratic sum, once the function is evaluated. Example:
Let be x= 2
Then f(2)= 4+2+1=7
Therefore the output is f(2) which is equal to 7.
Answer:
r = 5 ft
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
We are given the circumference
10 *pi = 2 * pi *r
Divide each side by 2 *pi
10 pi/ 2 pi = 2*pi*r/2pi
5 =r
