F(x) = a(x-h)²<span> + k
</span><span><u>Given that the vertex is (-3 -6):</u>
</span>f(x) = a(x + 3)² -6
<span>
<u>Given that it passes through (0.0), find a:</u>
a(0 + 3)</span>² - 6 = 0
<span>
9a - 6 = 0
9a = 6
a = 6/9 =2/3
<u>So the equation is :</u>
</span>f(x) = 2/3(x + 3)² -6
<span>
<u>Write the equation in standard form:</u>
</span>f(x) = 2/3(x² + 6x + 9) - 6
f(x) = 2/3x² + 4x + 6 - 6
f(x) = 2/3x² + 4x
<span>
Answer: </span>f(x) = 2/3x² + 4x<span>
</span>
The correct answer is 6/7.
Answer:
Step-by-step explanation:
To do this you have to figure each out in gallons per minute.
25/3 = 8 1/3. This means that the gas is going into the truck at a rate of 8 1/3 gallons per minute.
40/5 = 8. This means that the water is going into the tub at a rate of 8 gallons per minute.
The gas is flowing into the truck faster.
Answer:
Step-by-step explanation:
a. true because there are 0 cookies in the box at that point
b. true because the slope is the average weight of a cookie
c. false because the number of cookies will determine the weight of the box
d. false the box is 1oz and box+1 cookie=1.25 oz so the cookie is 1.25-1= .25oz
e. true if you continue the line until 13 cookies you have about 3.75oz
