Answer:
down
Step-by-step explanation:
y = -3x^2 +x +1
The coefficient of the x^2 term is negative so it opens facing down
X^2 coeffient
- means down
+ mean up

<h3>First,</h3><h3>Change the fraction to decimal. 2½=2.5</h3><h3 /><h3>Second,</h3><h3>Simply Multiply it by 3! 2.5×3=7.5</h3>
<h3>Therefore, you need 7.5 (7½) scoop of sugar to make 3 glasses of lemonade.</h3>
Step-by-step explanation:
1) the required equation in common form is:
(x-x₀)²+(y-y₀)²=r², where (x₀;y₀) - coordinates, where Michael is standing; r - the social distance;
According to the common form and given coordinates (x₀=-5; y₀=2; r=6) it is possible to make up the required equation:
<u>(x+5)²+(y-2)²=6².</u>
2) if the distance between two friends is:
![d=\sqrt{(-5-1)^2+(2-1)^2}=\sqrt{37}, \ then](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28-5-1%29%5E2%2B%282-1%29%5E2%7D%3D%5Csqrt%7B37%7D%2C%20%5C%20then)
this distance is longer than social (6 ft). For more info see the attachment.
The answer is 800000 because if the number before the number you want to round is 4 or less the number stays the same and all tue other numbers get chnges to 0's
