Answer:
v = 1
u = 2
Step-by-step explanation:
Given is a special right triangle with angle measures as follows:
90-60-30
The side lengths would be :
2x- x
-x
in the image it shows that the second side length (the one that sees angle measure 60) is from this we can conclude x = 1 so:
v = 1 and
u = 2
Dr /dt = 7
A = pi r^2
dA / dr = 2pir
dA/dt = dA/dr * dr/dt = 2pir * 7 = 14pir
when r = 12 rate of change of the area = 14*pi*12 = 168pi
= 527.79 cm^2 / minute to nearest hundredth
Answer:
242 m³ of space is there in the fort.
Step-by-step explanation:
Given that,
The dimensions of first box is 4 meters long, 8 meters wide, and 8 meters high.
The dimensions of the second box is 2 meters long, 7 meters wide, and 1 meter high.
Space left = Volume of first box - volume of second box
= (4)(8)(8) - 2(7)(1)
= 242 m³
So, 242 m³ of space is there in the fort.
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)
