Answer:
5
Step-by-step explanation:
26 × 10 ÷ 100 = 52 · x ÷ 100
260 = 52 · x
x = 5

Add the following polynomials:
All polynomials are already ordered according to their degree (exponent), and therefore you can just add straight down in columns.
For x3: 2 + 1 - 3 = 0
For x2: -4 + 6 + 2 = 4
For x: 6 - 8 -4 = -6
Constants: -3 + 12 - 7 = 2
The answer is:
4x^2 - 6x + 2
4/9 is smaller than 4/8 so the other fractions should be 4/8.____
This is what I did:
I used the fractions 4/8.5 and 4/8.4
Now we need to get rid of the decimal point for each of those fractions.
Find out what number you need to multiply the denominator so it is a whole number, not a decimal.
Take that number and multiply it by both numerator and denominator.
8.5 x 2 = 17
4/8.5 = (4*2)/(8.5*2) = 8/17 (This is your first fraction)
8.4 x 5 = 42
4/8.4 = (4*5)/(8.4*5) = 20/42 (This is your second fraction.
We conclude that the interval in which the function decreases is (1.5, 3]
<h3>
In which interval is the ball's height decreasing?</h3>
The ball is decreasing when the graph, reading from left to right, is going downwards.
Particularly, in this parabola that opens downwards, the graph will decrease after the vertex.
And we can see that the vertex is at x = 1.5
And we also see that the graph of the function ends at x = 3.
Then we conclude that the interval in which the function decreases is (1.5, 3]
