Which is the graph of f(x) = x2 – 2x + 3?
Answers
Answer:
Step-by-step explanation:
We cannot factor this function out which tells us that there are no zeros. The graph backs this up because we can see that there are none. The easiest way to graph this would start by plugging in points and making a table for yourself.
Lets start by plugging in -1.
(-1)^2-2(-1)+3 =6, this means we have a point at (-1,6).
Now lets plug in 0.
(0)^2-2(0)+3= 3 (0,3)
For plugging in 1
(1)^2-2(1)+3=2 (1,2) (this happens to be the vertex)
And lastly lets plug in 2
(2)^2-2(2)+3=3 (2,3)
Depending on how many points are needed, keep plugging in numbers like we did above.

Consider the following points on the graphs of y = cos(x) and y = cos(x + \pi/6), with the added vertical dashed lines:
Then what are 10c and 10d in that order?
Answers
Note that \(\cos a=\frac{4}{5}\). Since \(-\pi<a<0\), [tex)\sin \alpha<0\). So, by the Pythagorean theorem, \(\sin \alpha=-\frac{3}{5}\).
\(c=\cos \left(a+\frac{\pi}{6} \right) \\ \\ c=\cos a \cos \frac{\pi}{6}-\sin a \sin \frac{\pi}{6} \\ \\ c=\frac{4}{5} \cdot \frac{\sqrt{3}}{2}+\frac{3}{5} \cdot \frac{1}{2} \\ \\ c=\frac{4\sqrt{3}+3}{10} \\ \\ \therefore 10c=4\sqrt{3}+3\)
Note that \(\cos b=\frac{4}{5}\) and that \(0<b<\pi\), meaning \(\sin b>0\). So, by the Pythagorean identity, \(\sin b=\frac{3}{5}\).
\(d=\cos \left(b+\frac{\pi}{6} \right) \\ \\ d=\cos b \cos \frac{\pi}{6}-\sin b \sin \frac{\pi}{6} \\ \\ d=\frac{4}{5} \cdot \frac{\sqrt{3}}{2}-\frac{3}{5} \cdot \frac{1}{2} \\ \\ d=\frac{4\sqrt{3}-3}{10} \\ \\ \therefore 10d=4\sqrt{3}-3\)

When you have a graph, you can find the slope or coefficient next to x, by finding rise over run on the graph or using slope formula.
On the graph, from 0, 0, we go up or rise +6 and go right or run +1. Slope is 6/1 or 6.
Or, you have (0, 0) and (1, 6) as two definite points. Using slope formula
y2 - y1 over x2 - x1
6 - 0 over 1 - 0 = 6/1 or slope of 6.

Answer:
225 and 243.4
Step-by-step explanation:
Area of triangle = bh/2
A = 4*4.6/2
A = 9.2 cm sq
A of 2 triangles = 9.2*2 = 18.4 cm sq
Now, Area of 1 rectangle = lb --> 15*5 = 75 cm sq
A of 3 rectangles = 75*3 = 225 cm sq
Now, LSA = 225 cm sq. (excluding the triangles)
TSA = A of tr. + A of rec. = 18.4 + 225 = 243.4 cm sq

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.
Starting at 1:00 p.m., the temperature changes -4 degrees Fahrenheit per hour. Write an equation to find how many hours it will take to reach -1 *F.
Answers
Answer:
35 x (-4x) = -1 (9 hours)
Step-by-step explanation:
If your original temperature is 35, you can place that as your first term. Knowing that the temperature changes by -4 degrees per hour, we can make "x" = the number of hours until we get to -1° F.
35 x (-4x) = -1
-4x = -36
x = 9
35 x (-4x) = -1 (9 hours)
Step-by-step explanation:
If your original temperature is 35, you can place that as your first term. Knowing that the temperature changes by -4 degrees per hour, we can make "x" = the number of hours until we get to -1° F.
35 x (-4x) = -1
-4x = -36
