Hello,
1) cos t* tan t=cos t* sin t/cos t =sin t (if cos t≠0)
2)cos t * cosec t =cos t /sin t =√(1-sin² t) / sin t.
Answer:
D) Up on the left, up on the right
Step-by-step explanation:
When looking at the end behavior, the only term that matters is the 3x^4 term
as x goes to negative infinity
3 *(- inf)^4 = 3 * positive number = positive infinity
so as x goes to negative infinity f(x) increases
as x goes to infinity
3 *( inf)^4 = 3 * positive number = positive infinity
so as x goes to infinity f(x) increases
Answer:
If x = time in seconds, the answer is 1 second.
Step-by-step explanation:
The question is asking for the maximum height and the time it was achieved, so in terms of a graph, it is the vertex coordinates. Luckily this equation is in vertex form, so it gives us those points. The -1 in the equation is the x, but you invert this sign, because even thought the value on the graph is positive, it tells you to subtract 1, therefore adding -1, so for this part (the x part of the equation) remember to invert the sign.
The other part (the height) comes from the equation adding 45 at the end. This is the highest y point, and therefore the answer is (1,45), 1 second for 45 meters high.
