Answer:
5 feet
Step-by-step explanation:
7.How could you find how many papers Mason delivers in a year without doing any multiplication? What is the answer?
You can add 52 papers to Clare's total. She delivered 1 more paper a week for 52 weeks. 5,044+52=5,096
8. Ray needs to know the area of his floor so he can buy the right amount of carpet. The floor is 21 feet by 17 feet. What is the area of the floor?
If you multiply 21 by 17, you will get 357 square feet or 357 feet ²
9. Maria is buying flowers. Each tray of flowers cost $24. If she buts 15 trays, what will the total cost be?
If you multiply 24 by 15, you will get $360.

I pretty sure that if you want to make 5+4=3^2+x2, you just have to find a way to make 3^2, 9. So the value of x would have to be 0, because 0*0 is still zero. So the question would become 5+4=9+0, which is true.
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.
Requied equation is (x - 0)^2 = 4p(y - 0)
x^2 = 4py
But 0 + p = 0.75 => p = 0.75
Therefore, equation is x^2 = 4(0.75)y
x^2 = 3y
y = 1/3 x^2
