Answer: The radius is half the diameter and the diameter is double the radius
Step-by-step explanation:
The diameter is a straight line across the center of a circle. It goes from one side to another. The radius is half that, so a line starting from the center that goes to just one side.
Answer:
The answer is B
Step-by-step explanation:
Answers talk about rate of change meaning slope.
For function 1 we choose two points, they specify [1,2].
Use the slope formula for points (1,-3) & (2,3) = 6
For function 2, the equation is shown in y-intercept, basically the slope is (1/4)^x and if you replace x with [1,2] you get really low values.
For function 3 is easy since you can count the units with rise/run giving and slope of 2 or 2/1. <em>(2 and 2/1 is the same thing)</em>
265÷106=2.5,2.5×,100=250, so before tax, the cost would be 250$
<span>4/5 x for x = 5/8
= 4/5 * 5/8
= 4/8
=1/4
answer is </span><span>C) 1/4</span>
This is the point-slope formula:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
We know:
x=1
y=3
m=slope=2
plug those into the formula and get
Final answer:
