When a linear equation is in the form y = mx + c, the c, or constant, is the intercept on the y axis, meaning it crosses the y axis at (0, 1).
The gradient (1/3 in this case) is how much the y increments (or decrements) per increase of 1 of the value of x.
This would mean that there would be one point at (0, 1), and another at (3, 2). Draw a line from these two points and beyond, and that is the graph sketched.
Answer:
B would be your best choice
Step-by-step explanation:
X^2−9=0
Add 9 to both sides.
x^2−9+9=0+9
x^2=9
Take square root.
x=±√9
x=3 or x=−3
Answer:
x=3 or x=−3
V = (4/3)π*r^3
V' = 4π*r^2*r'
600 cm^3/min = 4π(30 cm)^2*r'
r' = (600 cm^3/min)/(4π(30 cm)^2) = 1/(6π) cm/min
The rate of change of radius is about 0.05305 cm/min.
Answer:
<u><em>300ft²</em></u>
Step-by-step explanation:
Step 1)
<u>Multiply The Walkway</u>
<u><em>(3 × 30)2 = 180ft²</em></u>
<u><em>(3 × 20)2 = 120ft²</em></u>
Step 2)
<u>Add The Walkway</u>
<u><em>180ft² + 120ft² = 300ft²</em></u>
Step 3)
<em><u>Multiply The Whole Area Including The Walkway and The Garden</u></em>
<u><em>30 × 20 = 600ft²</em></u>
Step 4)
<em><u>Subtract The Whole Area By The Walkway</u></em>
<u><em>600ft² - 300ft² = 300ft²</em></u>
Step 5)
<u><em>The Area Of The Garden is 300ft²</em></u>
