Answer:
When AB coincides with AC, the boundary of EAF maps exactly onto the boundary of CAD, implying that EAF dilates into CAD. So, the boundaries of EAF and CAD are similar.
The proportional relationship may be stated in different forms, but should be equivalent to this equation:
radius of Ab/ radius of Ac= length of arc EF/ length of arc CD
Explanations will vary, but should be based on the similarity of EAF and CAD. The proportional relationship follows from the fact that corresponding pairs of lengths in two similar figures have the same ratio.
Step-by-step explanation:
This is the exact answer so make sure you change it up a little.
The answer is 32.
Explanation:
Vertical opposite are equal.
The vertical opposite of angle 4 is 57.
<4 = 2x - 7
57 = 2x - 7
57 + 7 = 2x
64 = 2x
x = 64/2
x = 32
Answer:
2
Step-by-step explanation:
he value of K would be 2 because the function f(x) is the equation of a line. K is represented as the y-intercept. When a line is shifted down 2 units, the y-intercept also gets shifted down 2 units. In f(x) the y-intercept is zero. So the difference would be 2 units
Answer:
A. 3 < t < 9
Step-by-step explanation:
You have successfully found the values of t where the motion turns around (t=3 and t=10). Your knowledge of odd-degree polynomials tells you that the value of s(t) is decreasing for t < 3 (because the leading coefficient is negative), and is also decreasing for t > 10.
That is, the value of s(t) is increasing between t=3 and t=10, which means the particle is moving to the right in that interval. Since the function is only defined on the interval [0, 9] the particle is moving to the right on the interval (3, 9).
_____
At t=3 and t=10, the particle is stationary, moving neither right nor left.
