Answer:
A coordinate plane is shown. Points are graphed at negative 3 comma 2 and negative 1 comma negative 1. The points are connected by a line. −3 over 2 −1 over 2 3 over 2 Undefined
Step-by-step explanation:
Answer:
4.399231874 or radical (60.8/pi)
btw radical is square root
Step-by-step explanation:
Since the area of 1/4 (90/360) of the circle is 15.2 ft^2, the area of the whole circle must be
15.2*4 = 60.8.
Now, we can work backwards to find the radius using the are formula. Let's say the radius is x.
x^2pi = 60.8
x^2 = 60.8/pi
x = radical(60.8/pi)
550 grams because 3.85/7 = 0.55 and converted to grams is 550 grams per day
<h3>Given</h3>
- a line through (2, 7.5) and (-1, 0)
<h3>Find</h3>
- the line's equation in slope-intercept form
<h3>Solution</h3>
You can start with the 2-point form of the equation for a line:
... y = (y₂ -y₁)/(x₂ -x₁)·(x -x₁) +y₁
Filling in the given values, you get
... y = (0 -7.5)/(-1 -2)·(x -(-1)) +0
... y = 2.5(x +1) . . . . . simplify a bit
... y = 2.5x +2.5 . . . . slope-intercept form
