Answer:
A: f(x)=10cos(2π/5 x)+10
Step-by-step explanation:
The coefficient of x in the cosine argument of the function will be 2π/period. Since the period is 5, the coefficient is 2π/5. This observation eliminates choices B and C.
The description "not a reflection of the parent function over the x-axis" means the multiplier of the cosine function is not negative, eliminating choice D.
The remaining choice A matches the description.
1/3x + y = 4....subtract 1/3x from both sides
y = -1/3x + 4 <===
7 is digit for hundred thousands and 6 is for ten thousands so the answer is 800,000
Answer:
6.12
Step-by-step explanation:
tan 27≈0.51
Know that tan=
0.51=
Multiply 12 on both sides
6.12=x
No, not all of these questions are statistical.
The first question does Mary like snacks is a Yes or No question which doesn't provide any statistics.
