Answer:
Factsssssssssssssssssssssssssssssssssss
Step-by-step explanation:
1) don't do it
So let’s say the equation is x^2 (x squared) -4x + 8 = 0. So you have to eventually graph a palabara. So to get the vertex, you have to find the line of symmetry (this plays a big part). So the formula for the line of symmetry is x= -b/2a. So A is this equation is 1. B is -4. C is 8. So you would plug these numbers in and you get 2. So (2,0) is your like of symmetry. Now you have to plug 2 back in for x. So when you do that you get 4 so the vertex is (2,4). So the vertex is (2, 4) and basically what the vertex is is it is the highest or lowest point of a palabara. So you can tel if it opens up or down by looking is A is negative or positive. If A is negative the it opens down. If it is positive then it opens up. So now you just put points in. Create a t chart. Like x/y. So when X is 1 for example, y is 5. So you graph (1, 5) and you graph the point that is the same distance from the line of symmetry. You do this until you have 5 points. I hope this helps. It’s hard to teach this over text.
Base = (Percentage/Rate)
B = 119/0.85 = 140
There were 140 items on the test.
Y=-2/3x + 4 would be an equation that would fit
Answer:
It is 27.35 ft up the house
Step-by-step explanation:
The hypotenuse of the right triangle is 28 and the base is 6
We can use the pythagorean theorem to find how high it is
a^2 + b^2 = c^2
6^2 + b^2 = 28^2
36 + b^2 = 784
Subtract 36 from each side
36-36 + b^2 = 784-36
b^2 = 748
Take the square root of each side
b =sqrt(748)
b =27.34958866
It is 27.35 ft up the house
