Answer:
it would be 3
Step-by-step explanation:
because when you do 5×3=15 then +12= which gives you 27 and then do 3×3=8 then +18=which also gives you 27.
Answer:
(x)^2 (y)^2
---------- + --------- = 1

Step-by-step explanation:
The standard equation for an ellipse is
(x-h)^2 (y-k)^2
---------- + --------- = 1
a^2 b^2
The center is at (h,k)
The vertices are at (h±a, k)
The foci are at (h±c,k )
Where c is sqrt(a^2 - b^2)
It is centered at the origin so h,k are zero
(x)^2 (y)^2
---------- + --------- = 1
a^2 b^2
The center is at (0,0)
The vertices are at (0±a, 0)
The foci are at (0±c,0 )
The vertices are (±2,0) so a =2
The foci is 1
c = sqrt(a^2 - b^2)
1 = sqrt(2^2 - b^2)
Square each side
1 = 4-b^2
Subtract 4 from each side
1-4 = -b^2
-3 = -b^2
3= b^2
Take the square root
b=sqrt(3)
(x)^2 (y)^2
---------- + --------- = 1

Is that the math question?
7(2e - 1) - 3 = 6 + 6e
14e - 7 - 3 = 6 + 6e
14e - 10 = 6 + 6e
- 6e
8e - 10 = 6
+ 10
8e = 16
÷ 8
e = 2
Hope this helps!
Answer: maximum "safe" Force = 415.58 N
Step-by-step explanation:
<u>Length = 1.2 m</u>
lower bound is 1.15 (because it rounds up to 1.2)
upper bound is 1.24 (because it rounds down to 1.2)
<em>Note: 1.25 would round up to 1.3</em>
<u>width = 2.5 m</u>
lower bound is 2.45 (because it rounds up to 2.5)
upper bound is 2.54 (because it rounds down to 2.5)
<em>Note: 2.55 would round up to 2.6</em>
<u>Pressure = 150 N/m²</u>
lower bound is 147.5 (because it rounds up to 150)
upper bound is 152.4 (because it rounds down to 150)
<em>Note: 152.5 would round up to 155</em>
<u>Max "safe" Force means minimum Area and minimum Pressure (lower bounds)</u>
Force = Area x Pressure
= length x width x Pressure
= 1.15 x 2.45 x 147.5
= 415.58
