Answer:
Step-by-step explanation:
To add the two fractions, you need a common denominator. In this case, the lowest common denominator (LCD) is 9y. That's because 9y is divisible by both 3y and 9y.
The first fraction must be changed so that its denominator is 9y. Do this by multiplying both numerator and denominator by 3.
Finally, this answer can be simplified ("reduced") by dividing both numerator and denominator by 3, their greatest common factor.
The only way to do it is 1.8x1.8x1.8x1.8x1.8x1.8x1.8x1.8x1.8. Or just use a calculator. Sorry to let you down
Answer:
24
Step-by-step explanation:
s2+t2=r2
(7cm)2+t2=(25cm)2
49cm2+t2=625cm2
t2=625cm2
t2=625cm2-49cm2
t2=576cm2
t=24cm2

Answer: A. The period is 2pi/b</h3>
Explanation:
The value of 'a' out front in y = a sin(bx) determines the amplitude.
The b term helps us compute the period, which is 2pi/b for sine, cosine, secant, and cosecant functions.
For example, y = 2sin(3x) has an amplitude of 2 and period of 2pi/3
For tangent and cotangent functions, the period would be pi/b.
