Answer: Lower right corner
============================================
Explanation:
The information that the temperature rises 3 degrees per hour will tell us the slope here. The slope is rise/run = 3/1 = 3. Each time we move up 3 on the y axis, we move 1 spot to the right.
As you can see in the bottom right hand corner graph, we start off at a temperature of 20 degrees. This is the point (x,y) = (0,20)
Then one hour later (x = 1), the temperature y bumps up to y = 23. Another hour passes by (x = 2) and y becomes y = 26. And so on.
I hope this helps you
-cos²x= sin²x-1
4.sinx = sin²x-1+4
sin²x-4.sinx +3=0
(sinx-3)(sinx-1)=0

Answer:
<em>-4 4/5 deg F</em>
Step-by-step explanation:
3 pm: 5 1/5 deg
2 1/2 deg per hour for 4 hours = 2 1/2 deg * 4 = 10 deg
7 pm: 5 1/5 deg - 10 deg = -4 4/5 deg
Degree: 2
Leading coefficient: 1
Constant term: -30
Horizontal/X intercepts: (-6, 0) and (5, 0)
Vertical/Y intercept: (0, -30)
Here's a quick rundown: Distribute to find the standard form quadratic. Because it is quadratic, its degree must be 2. There isn't any number before the first variable, so it can be assumed to be 1. The last term, which doesn't have a variable and therefore the constant, is -30. By reversing the signs of the signs of the numbers in the factors, you can easily find the horizontal intercepts/X-intercepts/zeros/roots which are (-6, 0) and (5, 0). The constant term will in most cases also be the Y-intercept/horizontal intercept. Therefore the Y-intercept is (0, -30) This applies to this equation because there is nothing being multiplied across the entire equation.
