Answer:
20
Step-by-step explanation:
Divide 4 by 1/5 in decimal form, 1/5 in decimal form is 0.20. You can get the decimal form by dividing 1 by 5.
So 4/0.20 = 20.
The answer is C
5.76 x 10 ^3 means you move the decimal 3 times:
57.6> 576.0> 5760
The amplitude here would be 5
Should have subtracted 3x
Start with y = 2x. Subst. a for x and a+sqrt(3) for y:
a+sqrt(3) = 2a
Subtracting a from both sides: sqrt(3) = a
