F(−2)=14. Explanation: substitute x=− 2 into f(x). f(−2)=(3×(−2)2)−(−2). ××=(3×4)+2=12+2=14 .
.45 times 80
8 times 4 =32
8 times 0.5 =4
Just add these together to get 36.
Answer: y = -1x/5 -1
Step-by-step explanation:
Answer:
f(x) = -(x-3)^2 + 4
Step-by-step explanation:
(h; k) are the coordinates of the vertex.
On the graph are (3, 4), therefore we have:
f(x) = a(x-3)^2 + 4
We have the x- intercept (1,0) -> x=1; y=0.
Substitute them into the equation:
0 = a(1 - 3)^2 + 4
0 = a(-2)^2 + 4
4a + 4 = 0 | -4
4a = -4 |-4
a = -1
So, we have the answer:
f(x) = -(x-3)^2 + 4
Answer: Mike bought 120 pounds of fish and Millie bought 30 pounds of fish.
Step-by-step explanation:
If the ratio is 8 to 2 then 8/10 will be the probability of Mike buying fist and 2/10 will be the probability of Millie buying fish.
Now multiply each fraction by the total number of pounds to find how many pounds each bought.
8/10 * 150 = 1200/10 = 120
2/10 * 150 = 300/10 = 30
In this case, Mike bought 120 pounds of fish and Millie bought 30 pounds of fish.
