Answer:
See below
Step-by-step explanation:
Remember that quadratic functions are parabolas when graphed. The solutions are where the parabola crosses the x-axis.
1. The vertex of the parabola in f(x) is (0, 9) which is above the x-axis and the parabola opens up. So the parabola does not cross the x-axis. Therefore the solutions are imaginary.
2. The vertex of the parabola in g(x) is (9, 0) which is on the x-axis and parabola opens up. Therefore, there is a double solution.
3. The vertex of the parabola in h(x) is (-1, -9) which is below the x-axis and the parabola opens up. Therefore, there are two real solutions.
I know this is a long explanation, but that is a way of looking at the problem.
<h2>Answer:</h2>
13.391 ft
<h2>Explanations:</h2>
The schematic diagram of the given question is shown below;
The height of the tree is expressed as:
H = h +5
Determine the value of h using the SOH CAH TOA identity
Determine the height of the tree
Hence the height of the tree is 13.391ft
Answer:y=5
Step-by-step explanation:
Answer:
A. 25
Step-by-step explanation:
25 split into 5 groups, 5 in each of them.
There are 5 20's in 100 (the total)
25 = 5 + 5 + 5 + 5 + 5
I hope the explanation makes sense!
500% of 120
We can set up a proprtion
120/x=100/500<span> </span>
<span>120=0.2*x </span>
<span>120/0.2=x </span>
<span>600=x </span>
<span>x=600
Final answer: 600
