Answer:
k<3.5 or k>3.5
Step-by-step explanation:
k²-7k+12.25>0
(k-3.5)²
k²-7k+12.25
k²-2k·3.5+(√12.25)²
(k-3.5)²
k-3.5<0 or k-3.5>0
k-3.5 or k-3.5
Answer:
Percent error = 6.25%
Step-by-step explanation:
Percentage error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
<u>Given the following data;</u>
Experimental value = 4.5cm
Theoretical value = 4.8cm
<em>Substituting into the equation, we have;</em>
Percent error = 6.25%
Answer:
3 1/3
Step-by-step explanation:
2 1/2 = 5/2
1 1/3 = 4/3
5/2×4/3
5×4/2×3=
20/6=
10/3 = 3 1/3
Answer:
its 12
Step-by-step explanation:
Answer:
first option is correct
Step-by-step explanation:
finding area for upper rectangle
length = 16 miles
breadth = (2x - 1) miles
area of rectangle = l*b
=16 *(2x - 1)
16*2x - 16*1
=32x - 16
finding area for another rectangle
length = (5x + 5) miles
breadth = 4 miles
area of rectangle = l*b
= (5x + 5) * 4
=5x*4 + 5*4
=20x + 20
area of the figure = area of upper rectangle + area of another rectangle
=32x - 16 + 20x + 20
= (52x + 4) sq mi
