Answer:
There is sevral answers for one answer is David is blind another is far sighted
but the answer your looking for is C
Step-by-step explanation:
The formula for the general sin function is
where b is the period and c is the phase shift. We are given a period of
and the formula to solve for b is
. We set up to solve for b:
. Cross multiply to get
and b = 8. Now for the phase shift. The formula for that is -c/b, and since we already know b, and we have a phase shift value of pi/2, we solve for c:
and
. Therefore,
. Putting all that together into the equation with the A value of 6, we have
. Factoring out the 8 then, the final equation is
, third choice down.
1.2x10^4
Step-by-step explanation:
2.
negative exponent means it's a fraction so
4.5x10^-3 is 1/4500 or 0.0045 so
it's a very small number
1.
^4 means means move the decimal 4 spots
12×10^4 = 12,000
3.
^3 means move the decimal 3 spots
3.8 x 10^3 =
3800
4.
7.5x10^3 =
7500
