Answer:
EF
Step-by-step explanation:
A chord is a line segment whose endpoints both lie on the circle.
EF is the chord.
AC is the radius.
DC is a tangent.
FC is a secant.
The correct answer is the first choice.
Answer:
The slope is -5/7
Step-by-step explanation:
Slope is rise / run. In other words, the change in y / change in x:
![m= \frac{\Delta y}{\Delta x}\\m= \frac{y_2-y_1}{x_2-x_1}\\m= \frac{4-(-1)}{-2-5}\\m= \frac{5}{-7}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B%5CDelta%20y%7D%7B%5CDelta%20x%7D%5C%5Cm%3D%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5Cm%3D%20%5Cfrac%7B4-%28-1%29%7D%7B-2-5%7D%5C%5Cm%3D%20%5Cfrac%7B5%7D%7B-7%7D)
Answer:
47 days
Step-by-step explanation:
Since the patch of pads doubles in size every day, the lake would be half covered just one day before it was covered entirely.
Answer:
B. (3,0)(0 ,-6)
Step-by-step explanation:
What is intercept.?
Intercept are those points where a given line cuts across a given axis.
So for the equation y = 2x - 6
To find the intercept we will bear in mind that we are looking for two points.
The point where the line cuts both the x axis and the y axis .
And to determine that, we will set both x and y to be equal to zero and then solve for both.
So let x = 0
Y = 2x -6
Y = 2(0) -6
Y = -6
One point = (0 ,-6)
Let y = 0
Y = 2x -6
0 = 2x -6
6 = 2x
X = 3
One point = (3,0)
The two points are
(3,0)(0 ,-6)
