Answer:
52 cents
Step-by-step explanation:
0.88 times 4 is 3.52, which is buying 4 boxes separately which means you'd save 52 cents if you bought 4 at once
Answer:
- (-1, -5), (-1/2, -3), (-1, -9)
Step-by-step explanation:
<u>The function in vertex form is:</u>
- f (x) = a(x - h)² + k, where (h, k) is the vertex
- f(x) = (x - 1)² - 3
i) y = f(x) - 2 = (x - 1)² - 3 - 2 = (x - 1)² - 5 ⇒ h = 1, k = -5
<u>Minimum point:</u>
ii) y = f(2x) = (2x - 1)² - 3 = 4(x - 1/2)² - 3 ⇒ h = 1/2, k = -3
<u>Minimum point:</u>
iii) y = 3f(x) = 3((x - 1)² - 3) = 3(x - 1)² - 9 ⇒ h = 1, k = -9
<u>Minimum point:</u>
Answer:
13
Step-by-step explanation:
First find the average the numbers (40 / 4 = 10)
2 are more and 2 are less
7, 9, 11, 13
Answer:
![\textsf{C)}\quad g(x)=\dfrac{1}{2}(x-8)^2-8](https://tex.z-dn.net/?f=%5Ctextsf%7BC%29%7D%5Cquad%20g%28x%29%3D%5Cdfrac%7B1%7D%7B2%7D%28x-8%29%5E2-8)
Vertex = (8, -8)
Step-by-step explanation:
<u>Standard form</u>: ![y=ax^2+bx+c](https://tex.z-dn.net/?f=y%3Dax%5E2%2Bbx%2Bc)
<u>Vertex form</u>: ![y=a(x-h)^2+k](https://tex.z-dn.net/?f=y%3Da%28x-h%29%5E2%2Bk)
where (h, k) is the vertex
<u>Intercept form</u>: ![y=a(x-p)(x-q)](https://tex.z-dn.net/?f=y%3Da%28x-p%29%28x-q%29)
where p and q are the x-intercepts
Therefore, the form that most quickly reveals the vertex is
![g(x)=\dfrac{1}{2}(x-8)^2-8](https://tex.z-dn.net/?f=g%28x%29%3D%5Cdfrac%7B1%7D%7B2%7D%28x-8%29%5E2-8)
The vertex is (8, -8)
Answer:
432 flights are expected to arrive at time.
Step-by-step explanation:
48/50= 0.96
0.96 x 450= 432
