Answer: 3 1/2 ( mixed number)
Step-by-step explanation:
- First you have to put 3.5 into na fraction
- In a fraction it is 35/10
- as a mixed number, it would be: 3 5/10 ( a mixed number )
- Bur we still have to simplify so simplified would be: 3 1/2 ( mixed number)
Answer:
D
Step-by-step explanation:
When iron reacts with air and water, it forms Iron (III) oxide, also known as rust, which is reddish-brown.
BDC is adjacent (Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap.)
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
