Answer:
(2, 1).
Step-by-step explanation:
f(x)=2x^2-8x+9
Find -b/2a first, it's -(-8)/2(2)=8/4=2.
Then find the y-coordinate of the vertex.
2(2)^2-8(2)+9=2(4)-16+9=8-16+9=-8+9=1
Answer:

Step-by-step explanation:
I took the test got a 100
There are four banana, one strawberry and one water-melon smoothies, six in all.
Assuming all smoothies are identical when we pick, then the probability of picking a particular one is one divided by the total number (of smoothies).
Since there are four banana smoothies, the probability of picking a banana smoothie is four divided by six, or four-over-six, or two-thirds.
There are now five smoothies remaining, of which three are banana. Therefore the probability of picking another banana is three-over-five, or three fifths.
The final probability is the product of the individual (we call it a two-step experiment), or two-third multiplied by three-fifths, equal to two-fifths, or forty percent.
Recall that if the first banana smoothie had been put back in the batch, the probability would come out different.
A = Ao(x)^t
Ao = 500
A = 500(x)^t
400 = 500 (x)^1
x = 4/5
A = 500(4/5)^t << The exp eqn
Answer:
100 times larger
Step-by-step explanation:
The digit 3 in 832,719 has the value of 30,000.
The digit 3 in 824,319 has the value of 300.
30,000/300 = 100
