Answer:
The initial goal was $25019.154.
Step by step Explanation:
Assuming the original goal is denoted as x.
As stated
Another Kickstarter initiative for an iPad stylus secured 1,253% of its target, accumulating a total of $313,490.
1253% can be expressed as a decimal.

= 12.53
Thus, the equation is rearranged to
12.53 × x = 313490
12.53x = 313490

x = $ 25019.154
This means the initial goal stands at $25019.154.
Answer:
a. Alice
b. Briana
c. 0.51 minutes
Step-by-step explanation:
a. Alice's formula is applicable for any t > 0 minutes, while Briana’s is only applicable when
2t - 1 > 0
2t > 1
t > 1/2 minutes
b. They complete the race when their total distance equals 5 kilometers. For Alice:
t/4 = 5
t = 20 minutes
For Briana:
√(2t - 1) = 5
2t - 1 = 25
2t = 26
t = 13 minutes
c. They reach the same point when they have traveled the same distance, expressed as:
t/4 = √(2t - 1)
(t/4)² = 2t - 1
t²/16 = 2t - 1
t² = 16(2t - 1)
t² = 32t - 16
t² - 32t + 16 = 0
Using the quadratic formula:







Only the second solution fits this scenario because the race concluded before they took 31.49 minutes.
In a step graph plotted on a coordinate plane, each horizontal section is precisely 1 unit wide. The left endpoint of each segment displays a closed circle, while the right endpoint shows an open circle. The leftmost segment stretches from (-3, -5) to (-2, -5). Every subsequent segment is positioned 1 unit higher and shifted 1 unit rightward compared to the one prior. The rightmost segment extends from (4, 2) to (5, 2). The representation is a direct reflection of the floor function, which produces horizontal segments with closed circles on the left and open circles on the right.

Begin by subtracting 379 from both sides of the equation.
This results in: 
Next, divide both sides by -24, which gives us: x = 13.
That corresponds to 13 weeks.
