Answer:
c. number shows the proportional relationship between x and y...
the answer is multiply the previous value by 2
Step-by-step explanation:
The quadratic equation is in factored form, which is f(x) = (x - a)(x - b), where a and b are the x-values for the x-intercepts.
The x-values for the x-intercepts are 4 and -2. We know that the y-value at any x-intercept must be 0 (otherwise it isn't an x-intercept).
Thus, either the points (4,0) or (-2,0) must be your answer (the question is only asking for one x-intercept).
Answer:
14 units
Step-by-step explanation:
We are given that the area between two concentric circles is 
We have to find the length of chord in the larger circle that is tangent to the smaller circle.
Let
be the radius of two circles.
be the radius of small circle and
be the radius of large circle
We know that area pf circle=
Area of large circle =
Area of small circle =
Area between two circles =
Area of large circle -Area of small circle=


By pythagorus theorem




Length of chord=
Hence, the length of chord of the larger circle =
units
