F(x) has exactly one intercept at the origin. g(x) is transformed from f(x) by flipping it (the minus sign at the x2) and then lifting it by 7 units. This means that the resulting mountain parabola will have two x-intercepts. Mathematically, a parabola has exactly one x-intercepts when its discriminant equals 0, it has 2 intercepts for D>0.

D= b^{2} -4ac

For g(x), a=-1, b=0 and c=7, so D=28, meaning 2 intercepts!

Answer:

The function started facing up with a vertex at (0,0) since 7 was added before squaring , the graph shifts 7 units up so the vertex at (7,0) also , the function is negative do the graph is pointing down.


This means that there are two x- intercepts in g(x) and there was one x- intercepts in f(x).

In a circle an arc length 10 is intercepted by a central angle of 2/3 radius
djverab [1.8K]

We have been given that in a circle an arc length 10 is intercepted by a central angle of 2/3. We are supposed to find the radius of the circle.

We will use arc-length formula to solve our given problem.

l=r\theta, where,

l = Arc length,

r = Radius,

\theta = Central angle corresponding to arc length.

Upon substituting our given values in arc-length formula, we will get:

10=r\cdot \frac{2}{3}

10\cdot \frac{3}{2}=r\cdot \frac{2}{3}\cdot \frac{3}{2}

5\cdot \frac{3}{1}=r

15=r

Therefore, the radius of the given circle would be 15 units.
