Answer:60
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.
Answer:
29
Step-by-step explanation:
7x + yz = 7 x 2 + 3 x 5 = 14 + 15 = 29
