Answer: Nobody knows the trouble ive seen
Step-by-step explanation:
You don't need to understand the construction or why it works. You only need to accept the fact that it does. You can figure out the answers to this question by looking at the picture.
RT is tangent to circle Q -- TRUE. That is the point of the construction.
QT is a radius of circle Q -- TRUE. Q is the center and T is on the circle. A line segment from the center to a point on the circle is a radius.
m∠QSR = 90° -- FALSE. Those points lie on the same line. The measure of the angle is 180°.
QS = QT -- FALSE. S lies inside circle Q, so is closer to the center than T, which lies on the circle. (For some choice of point R, S might lie on the circle, but because this statement is not always true, it must be considered false.)
ΔRTQ is a right triangle -- TRUE. A tangent line is always perpendicular to the radius to the point of tangency. The construction succeeds because RTQ is inscribed in semicircle RTQ (centered at S). Such a triangle is always a right triangle.
Answer:
The y-intercept is (0,0), obtained by setting x = 0 in the given function.
The x-intercepts are (0,0) and (0.4/0.008, 0), or (0,0) and (0,50).
Step-by-step explanation:
It's best to label a quantity like this one: y = x(0.4 - 0.008x). Perform the indicated multiplication so as to obtain a quadratic equation of the form y = ax^2 + bx + c: 0.4x - 0.008x^2; here, that works out to y = -0.008x^2 + 0.4x + 0. The y-intercept is (0,0), the value of the function when x = 0.
The x-intercepts are found by setting y=0 and solving for x: (0,0) and (50,0)
