558.7 , because 74 x 7.55 = 588.7 , it would be his total for the two weeks
18
Because 6•3= 18
Hope this helped
Answer:
![y = 2x^2 + 1](https://tex.z-dn.net/?f=y%20%3D%202x%5E2%20%2B%201)
Step-by-step explanation:
The graph you see there is called a parabola. The general equation for the graph is as below
![y = a*x^2 + b](https://tex.z-dn.net/?f=y%20%3D%20a%2Ax%5E2%20%2B%20b)
To find the equation we need to find the constants a and b. The constant b is just how much we're lifting the parabola by. Notice it's lifted by 1 on the y axis.
To find a it's a little more tricky. Let's use the graph to find a value for a by plugging in values we know. We know that b is 1 from the previous step, and we know that when x=1, y=3. Let's use that!
![3 = a * (1)^2 + 1\\2 = a](https://tex.z-dn.net/?f=3%20%3D%20a%20%2A%20%281%29%5E2%20%2B%201%5C%5C2%20%3D%20a)
Awesome, we've found both values. And we can write the result.
![y = 2x^2 + 1](https://tex.z-dn.net/?f=y%20%3D%202x%5E2%20%2B%201)
I'll include a plotted graph with our equation just so you can verify it is indeed the same.
To be honest the correct answer would be just 5 because of estimation
so it would be 5.1754386 circle the 5 underline the 1 and Badda bing Badda boom because if something is bigger than 5 you round up one if its lower than leave your beautiful number
Answer:
The second one. The -2y should have been +2y
Step-by-step explanation:
a negative multiplied by a negative gives you a positive
