all i can tell ya hope it helps!!
Answer:
f(x) = -x²
Step-by-step explanation:
Writing f(x) = -x² in vertex form gives f(x)=-(x-0)^2+0 which shows that the vertex (h,k) is at (0,0)
The other equations written in vertex form do not have (h,k) = (0,0)
Answer:
B is the correct answer
Step-by-step explanation:
Let’s write the equation for Tim according to the question, that is t = 14h
Now for sheri, looking at the table, we can see that in two hours, he sells 14 tickets . This means that he sells at an average rate of 7 tickets per hour
Modeling his selling rate, with t being the number of tickets and h being the number of hours, we have;
t = 7h
Tim’s rate is t/h = 14
While sheri’s rate is t/h = 7
We can see that Tim’s rate is double Sheri’s rate
Answer:
t = 3.4285 or 24/7
Step-by-step explanation:
Sub f = 2t + 1 into the other equation
7(2t + 1) = 55
Expand
14t + 7 = 55
Rearrange
14t = 55 - 7
14t = 48
t = 3.4285 or 24/7
Answer:
219
Step-by-step explanation:
The figure has the shape of a trapezoid. We find the area of the trapezoid and subtract the area of the rectangular door.
area of trapezoid = (base1 + base2)h/2
area of trapezoid = (20 ft + 12 ft) * 15 ft / 2
area of trapezoid = 32 ft * 15 ft /2
area of trapezoid = 240 ft^2
area of rectangle = length * width
area of rectangle = 7 ft * 3 ft
area of rectangle = 21 ft^2
area to be painted = area of trapezoid - area of rectangle
area to be painted = 240 ft^2 - 21 ft^2
area to be painted = 219 ft^2
Answer: 219 ft^2
