Answer:
True False True
Step-by-step explanation:
1. A circle has 360 degrees in its interior. 360 - 130 (this is given) degrees = 230 degrees. This means it's TRUE
2. The area of the shaded sector is the degrees in the central angle that contains the sector, multiplied by the area of the circle. This means that the area is pi*r^2*angle. The radius is 10, and the angle is 230 degrees, so the answer is 100*230/360 pi = 23000/360 pi, which simplifies to 575/9 pi. This is FALSE.
3. The area of the shaded sector is area of the circle - area of the shaded sector. The area of the circle is pi r^2, which is 100 pi. 100 pi - 575/9 pi = 325pi/9, so this is TRUE
A linear regression equation is a line so it has a form of y = mx + b, which is an equation of a line. You will also see it as Y = a + bX. In the form of Y= a +bX the b is the slope.
There are different methods to fitting a line and the most common method is the method of least-squares.
10 in the first power
so yeah
Answer: 13300
Step-by-step explanation:
Part C: Treat these two expressions as separate functions. Then f(x) = 4^(-x) and g(x) = 2^x + 3. Graph these functions separately on the same set of coordinate axes. Determine the coordinates of the point of intersection of the two graphs. That's your "solution," or at least the x-component of it. To find the y-component, substitute your "solution" into either f(x) or g(x). Write your final solution in the form (x,y).
