Answer:
Yes, the solids are similar.
Step-by-step explanation:
To figure this out you have to test the ratios of the corresponding dimensions. If they are all equal, they are similar.
28/21=1.33333
22/16.5=1.33333
24/18=1.33333
As they all equal 1.33333, the solids are similar
Answer:
36
Step-by-step explanation:
N = 6
S = 0 n = 1
2(1) - 1 = 1
S = 0 + 1 = 1
n = n + 1
n = 1 + 1
n = 2
S = 1 n = 2
2(2) - 1 = 3
S = 1 + 3 = 4
n = n + 1
n = 2 + 1
n = 3
S = 4 n = 3
2(3) - 1 = 5
S = 4 + 5 = 9
n = n + 1
n = 3 + 1
n = 4
S = 9 n = 4
2(4) - 1 = 7
S = 9 + 7 = 16
n = n + 1
n = 4 + 1
n = 5
S = 16 n = 5
2(5) - 1 = 9
S = 16 + 9 = 25
n = n + 1
n = 5 + 1
n = 6
S = 25 n = 6
2(6) - 1 = 11
S = 25 + 11 = 36
n = n + 1
n = 6 + 1
n = 7 > N

-3x4=-12
9+-12=-4
So the y-intercept is -4
Since you already know the gradient you can form:
y = -3x -4
Answer:
The solution of the system of equations are the points (-2,-6) and (4,6)
Step-by-step explanation:
we have
----> equation A
----> inequality B
we know that
The solution of the system of equations is the intersection point both graphs
To graph the linear equation, find the intercepts
<em>Find the y-intercept</em>
The y-intercept is the value of y when the value of x is equal to zero
For x=0
The y-intercept is the point (0,-2)
<em>Find the x-intercept</em>
The x-intercept is the value of x when the value of y is equal to zero
For y=0
The x-intercept is the point (1,0)
Plot the intercepts to graph the linear equation and find the intersection points with the quadratic equation
The intersection points are (-2,-6) and (4,6)
see the attached figure
therefore
The solution of the system of equations are the points (-2,-6) and (4,6)
