Question

Mathematics i hope you help me with this​

Answer 1

Answer: B.
`0 < a_2 < a_1`

Step-by-step explanation:

The coefficients tacked onto the trig functions tell us how vertically stretched the curves are. The dashed curve, representing
`y_1(t)`, is taller than the solid curve. Therefore
`a_1` must be larger than
`a_2`

For the sine curve, note how it is increasing after we pass through t = 0. This indicates we have
`a_1` as a positive number. The value of
`a_2` is positive because the point (0,k) on the cosine curve has k being positive.
