Answer:
y'(x) = 8x
Step-by-step explanation:
Simplifying gives:
y = 4x^2
y'(x) = 8x
Answer:
First Graph:
Slope = - 4/5
Point-Slope Form: y - 3 = - 4/5 (x + 2)
Point: (-2, 3)
Second graph:
Slope = 4
Point-Slope Form: y + 6 = 4 (x + 1)
Point: (-1, -6)
Step-by-step explanation:
First graph has two points: (-2, 3) & (8, -5)
Use the two points to find the slope using the Slope-Formula
Slope-Formula: y2 - y1/x2 - x1
m = slope
m = - 5 - 3/8 - - 2
m = - 8/10
m = - 4/5
The slope of the line will be - 4/5
Now for Point-Slope Form, we’ll need to use the two points with the slope to identify the Point-Slope Form of the graph
Two points: (-2, 3) & (8, -5)
Slope: - 4/5
Point-Slope Formula: y - y1 = m (x - x1)
Point-Slope Form: y - 3 = - 4/5 (x + 2)
The point will be: (-2, 3)
I understand by "ratio less then 1" for example this:
0.4:1
You can read this scale like this: 0.4 cm on the map corresponds to 1 cm of the actual object.
so let's say the object is 0.4 cm on the map: then it's 1 cm in reality, bigger!
so a ratio less than one means the actual object is bigger!
Answer:
Answer is in bold form
Step-by-step explanation:
Given
radius = 3feet
Height = 6feet
Volume of the cylinder = πr²h
Volume of the cylinder = 3.14 * 3² * 6
Volume of the cylinder = 169.56ft³
volume of the cone = Volume of cylinder/3
volume of the cone = 169.56/3
volume of the cone = 56.52ft³
Volume of the sphere = 4/3πr³
Volume of the sphere = 4/3*3.14*(3)³
Volume of the sphere = 4 * 3.14* 9
Volume of the sphere = 113.04ft³
65 miles per hour means that for each hour, it goes 65 miles
65 miles*2 hours= 130 miles
Final answer: 130 miles
