Answer:x=90
Step-by-step explanation:100+2x=10+3x
100-10=3x-2x
90= x
The slope is -4 and another point would be (19,12) and the equation for the line (in slope-intercept form) is y=-4x+88
The standard equation of the circumference is given by:
(x ─ a) ^ 2 + (and ─ b) ^ 2 = r ^ 2
Where,
The ordered pair (a, b) represents the center of the circle.
The radius of the circumference is r.
In this case to find the radius of the circumference we must find the distance between the points (1, -6) and (7, -2).
We have then:
r = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
r = root ((7-1) ^ 2 + (-2 - (- 6)) ^ 2)
r = 2 * root (13)
The equation of the circumference will be:
(x ─ 7) ^ 2 + (y + 2) ^ 2 = (2 * root (13)) ^ 2
(x ─ 7) ^ 2 + (y + 2) ^ 2 = 52
Answer:
(x ─ 7) ^ 2 + (y + 2) ^ 2 = 52
Answer:
The correct option is 1.
Step-by-step explanation:
The given parent function is
1. Domain of the function is all positive real number including 0.
2. Range of the function is all positive real number including 0.
3. It is an increasing function. It increases at decreasing rate.
First graph increase at decreasing rate and it starts from (-4,-1), therefore the required function is
Therefore graph 1 is an example of a function whose parent graph is of the form y = √x.
Second graph is a parabola, so it is the graph of a quadratic function.
Third graph is a rectangular hyperbola, so it is the graph of a rational functions.
Fourth graph is increasing at increasing rate, so it is the graph of an exponential function.
Therefore options 2, 3 and 4 are incorrect.
